Systemic Liability Hearing – AI Expert Testimony

Threshold 1: Foreseeability of Harm

Counsel: Please explain the concept of foreseeability of harm in legal terms and its relevance to negligence.

Witness: Foreseeability of harm means the predictable likelihood that certain actions or failures could result in injury or damage. In negligence law, courts ask whether a reasonable person in the defendant’s position could or should have anticipated the harm that occurred. If the harm was not reasonably foreseeable, liability in negligence will not attach. Conversely, if a harm of that general type was foreseeable (even if the full extent of damage was not), the defendant may still be held liable. Indeed, English law has long treated reasonable foreseeability of harm as a necessary ingredient in establishing a duty of care. This threshold focuses the court on whether the risk of harm was evident enough that a responsible actor or institution ought to have taken precautions. It prevents holding defendants liable for truly unexpected accidents, while ensuring they account for risks that were or ought to have been known.

Counsel: How does foreseeability apply when assessing systemic failures by public institutions or governments? Can you give an example?

Witness: Foreseeability applies not only to individuals but also to institutions – if an authority had prior warnings or knowledge of a danger, any resulting harm was not an unforeseeable mishap but a predictable outcome. Take the Grenfell Tower fire of 2017 as a stark example. Years before that tragedy, a 2009 high-rise fire at Lakanal House had killed six people. The coroner from Lakanal House explicitly urged the government to update building regulations “with particular regard to the spread of fire” on external surfaces. However, those safety recommendations were not implemented. When Grenfell’s cladding ignited in 2017, leading to 72 deaths, attorneys for the victims argued the disaster “was foreseeable”, given the earlier incident and unheeded coroner’s warnings. In the Grenfell Inquiry, counsel Michael Mansfield QC condemned the failure to act after Lakanal, calling it a “betrayal of the [Lakanal] jury and coroner”. In other words, regulators knew or ought to have known the tower’s cladding and fire safety defects posed a lethal risk. The foreseeability threshold was clearly met: a reasonable authority would have anticipated the danger of a catastrophic fire. This example shows how foreseeability in a systemic context is established by prior incidents, expert reports, or internal knowledge that signaled a serious risk. When such signals are ignored, the resulting harm is not a random accident but a foreseen consequence – strengthening the case for institutional liability.

Threshold 2: Duty of Care

Counsel: What is meant by a duty of care in law, and how is it determined in negligence cases?

Witness: A duty of care is a legal obligation to avoid conduct that foreseeably harms others. In negligence jurisprudence, not every harmful outcome leads to liability – the claimant must show the defendant owed them a duty of care in the circumstances. Under the Caparo test (from Caparo Industries plc v. Dickman [1990]), courts consider three elements to decide if a duty of care arises: (1) was the harm to the claimant reasonably foreseeable, (2) was there a relationship of sufficient proximity between claimant and defendant, and (3) is it fair, just and reasonable to impose a duty. All three factors typically must be satisfied for a novel duty to be recognized. In many situations, the law already recognizes a duty (for example, landlords owe duties to tenants regarding safety of premises, doctors to patients, employers to employees). The essence is that if one’s conduct or responsibility position places others at foreseeable risk, the law may require that person or institution to take reasonable care to prevent harm. Failing such care, if a duty is established, can lead to negligence liability.

Counsel: How does this apply to public institutions or systemic contexts? Do institutions owe duties of care, and can breaches be argued at a systemic level?

Witness: Yes, public bodies and larger entities can owe duties of care, though courts sometimes limit such duties for policy reasons. Institutions have well-defined duties in certain settings – for instance, prison authorities owe a duty of care to inmates, hospitals to their patients, and local authorities to children in their care. A poignant example involved the duty of police to protect individuals from known threats: in Osman v UK, the European Court of Human Rights noted that authorities must act if they “knew or ought to have known at the time of the existence of a real and immediate risk to the life of an identified individual” and could have reasonably avoided it. This principle has been applied to hold states accountable under human rights law even when domestic courts, for policy reasons, refused to impose a common-law duty of care (as happened in the Hill and Michael cases, where police were found not liable in negligence for failing to prevent murders). The Osman test essentially recognizes a positive duty on authorities to protect life once a serious risk is foreseeable and specific. More generally, statutory duties and the corporate “duty to prevent” concept have emerged to address systemic harm – for example, the UK’s Corporate Manslaughter and Corporate Homicide Act 2007 imposes liability on organizations if gross management failures in their duty of care cause death. In short, while individuals within institutions may not be personally liable for every misstep, the institution itself can be found to owe duties to those under its charge or affected by its policies. If the institution’s structure or culture results in breaching that duty, the law can attribute liability at the systemic level. The duty of care threshold thus underpins the idea that harm is not only a matter of individual fault but can flow from institutional responsibility (or irresponsibility) toward the public.

Threshold 3: Breach of Duty (Systemic Failure)

Counsel: Once a duty of care is established, how do we evaluate breach of duty? And what does it mean in the context of systemic failure as opposed to an individual lapse?

Witness: A breach of duty occurs when the obligated party fails to meet the standard of care expected under the circumstances. In negligence law, this is often phrased as falling below the conduct of a reasonable person (or reasonable institution) in that position. For an individual, breach might be a specific act of carelessness. For an institution, breach may manifest as systemic failure – a pattern or practice that shows the organization itself operated below lawful standards. We assess breach by looking at what the duty required and how the defendant’s actions or omissions measured up. Importantly, when breach is argued at a systemic level, it means the failure was not an isolated error by a rogue employee, but rather rooted in policies, culture, or widespread practices. For legal purposes, the conduct of the institution is gauged against what a reasonable, safety-conscious system would have done. For example, an inquiry might ask: Did the hospital have in place adequate procedures to protect patients? Did a housing authority follow fire safety regulations across the board? If the answer is no – and particularly if multiple warnings or incidents occurred – that indicates a systematic breach of duty, not just a one-off mistake.

Counsel: Can you provide a case study illustrating systemic breach of duty?

Witness: One of the clearest case studies is the Mid Staffordshire NHS Trust scandal in the UK (2005–2009). This was not a single act of negligence, but a pervasive breakdown of care standards. An independent inquiry led by Robert Francis QC found “shocking” and systematic failures at Stafford Hospital – patients were “routinely neglected, humiliated and in pain” as the Trust’s management focused on cutting costs and hitting targets rather than basic care. Between 400 and 1,200 more people died at Mid Staffordshire than would be expected, statistically, over those years. This appalling outcome was attributed to systemic neglect: staffing was gutted, safety alerts were ignored, and a culture of denial prevailed. Many patients suffered infections, falls, and dehydration (some were so thirsty they drank water from flower vases), indicating breaches of the most fundamental duties of care. Here, breach did not stem from one nurse or one bad day – it was the hospital system’s failure at every level. Notably, evidence showed that numerous staff had raised concerns about unsafe practices, but management ignored or silenced these warnings. The inquiry concluded the Trust’s leadership breached its duty to patients on a systemic scale, prioritizing bureaucratic targets over human life. This illustrates how breach of duty can be proven by a pattern of entrenched failings. Legally, it was recognized that an institution can be so out of line with reasonable standards that it is effectively “grossly negligent” as a whole. The Mid Staffordshire case led to reforms in NHS oversight, underscoring that when systems fail so abjectly, liability and accountability are not only possible – they are imperative.

Counsel: The term “systemic failure” suggests multiple missteps over time. Is there legal recognition of such cumulative breaches?

Witness: Absolutely. Courts and inquests do recognize cumulative failings. In fact, under human rights law, there’s a concept of a “systems duty” (a subset of the duty to protect life) which can be breached by systemic negligence. For instance, the European Court of Human Rights has held that states must have effective regulatory systems to safeguard lives (for example, proper building safety regimes, appropriate medical oversight in detention, etc.). A breach of the systems-duty occurs when the system as designed or operated is deficient and thereby puts lives at risk. An operational example can be drawn from the Grenfell Tower context: If an entire building regulation regime permits flammable cladding, or if enforcement is so lax that known fire risks go unremedied, that is a systemic breach. It is essentially a breach by design or omission in the system, not merely by one actor. The law is increasingly receptive to evidence of institutional dysfunction – showing, for example, that all the checks and balances failed simultaneously, which in and of itself proves an overall breach. Thus, when we speak of breach in systemic terms, we are showing the court that the standard of care was violated on an organizational level, through structural shortcomings, underfunding, poor training, or cultural attitudes that fell below legal requirements. It moves the narrative from “one person’s carelessness” to “the organization’s way of doing things was negligent.”

Threshold 4: Causation

Counsel: Even if a duty is breached, we must link that breach to the harm. How is causation established in law, and what challenges arise in systemic harm cases?

Witness: Causation means proving that the breach of duty actually caused or materially contributed to the harm suffered. Legally, this often involves two aspects: factual causation (the “but for” test – but for the defendant’s breach, would the harm have occurred?) and legal causation (is the connection sufficiently direct, or was the harm too remote?). In a straightforward case, one asks: did the negligent act lead to the injury? In complex or systemic cases, causation can be more challenging because multiple factors and actors might be involved. However, the law does not require a single cause – if a defendant’s breach materially contributed to the harm, or set in motion a chain of events leading to harm, causation can be established. In negligence claims resulting in death, for example, the prosecution or plaintiff must show the breach was at least a significant cause of death. It is not a defense to say “other factors also contributed” when the defendant’s failure clearly played a role. In systemic contexts, we often deal with concurrent causes (e.g. policy decisions, economic factors, individual errors all combining). Courts may use a pragmatic approach – did the institutional failure significantly increase the risk of harm or accelerate its occurrence? If yes, causation is satisfied in law.

Counsel: Can you offer evidence where systemic policy decisions were causally linked to harm, to illustrate this threshold?

Witness: A striking example comes from public health research on the effects of austerity in the UK. While not a single incident, the cumulative impact of government policy can be causally assessed. A 2022 study in the Journal of Epidemiology & Community Health found over 330,000 excess deaths in Great Britain from 2012–2019 that “can be attributed to spending cuts to public services and benefits” under austerity. In other words, statisticians and epidemiologists linked the policy (reduced social safety nets, NHS funding constraints, etc.) to a measurable increase in mortality. The authors concluded many people died prematurely due to reduced income, ill-health, poor nutrition and housing, and social isolation – all downstream effects of austerity measures. This analysis implies a causal connection: the breach (if one views it as a breach of government’s duty to safeguard basic welfare) materially contributed to the deaths. To phrase it legally, but for those severe cuts, thousands of those individuals might not have died when they did. Another domain is the welfare system’s link to mental health crises. The Department for Work and Pensions (DWP) in the UK has been associated with numerous cases of claimant suicides. An official review by the National Audit Office revealed at least 69 suicides could be linked to problems with benefit claims over just a six-year period. Families and coroners reported that people took their lives after benefits were cut off or harsh procedures were applied, indicating DWP’s actions played a role in the deaths. In one inquest, a coroner directly found that DWP’s failures contributed to a claimant’s deteriorated mental state and eventual suicide. Such findings underscore causation: the systemic practices (e.g. sudden termination of benefits without adequate support) were a proximate cause of foreseeable harm (extreme distress leading to loss of life). Legally, these cases would argue that the government’s breach of its duty to administer benefits safely and humanely had a direct causal link to the injuries and deaths. While causation in complex systems can be contested, the presence of statistical evidence, expert testimony, and patterns of harm can satisfy courts that “on the balance of probabilities,” the systemic failure was a factual cause of the harm. The key is showing a traceable chain from policy or practice to outcome – something increasingly feasible through data and investigative findings.

Counsel: In some situations there might be intervening events or multiple contributors. How do courts handle causation in such multi-factor scenarios?

Witness: Courts acknowledge that real-world harms often have multiple causes. The law does not demand absolute certainty or sole causation – rather, it requires that the defendant’s breach was a substantial factor in producing the harm. In multi-factor cases, courts may use tools like the material contribution test (if the defendant’s breach materially contributed to the harm, that suffices even if other factors also contributed). For instance, if a public housing authority fails to maintain fire alarms (breach) and a negligent tenant drops a candle (another cause), both can be held to have caused a resulting fire. An intervening act only breaks the chain of causation if it was unforeseeable and sufficient on its own to cause the harm. In systemic cases, many contributing causes (like socioeconomic factors, individual choices) are usually foreseeable consequences or concurrent conditions rather than truly independent, superseding causes. Austerity’s health effects, for example, may be mediated by individual lifestyle or local service issues, but those are part of the risk the policy creates – not a reason to exonerate the policy-makers. The courts would likely view such policies as setting the stage for harm. Similarly, in environmental cases, a regulator’s failure to enforce pollution limits might coincide with a company’s negligence and a freak weather event to produce an environmental disaster; unless the later event was completely unforeseeable, the regulator’s and company’s breaches remain causative. Ultimately, if the plaintiff can show that the harm flowed from the defendant’s systemic failure in a direct and foreseeable way, causation is established. The presence of other contributing factors may influence apportionment of liability but does not erase the causal link from the breached duty to the damage.

Threshold 5: Pattern Evidence

Counsel: What is pattern evidence, and why is it important in establishing systemic liability?

Witness: Pattern evidence refers to proof of repeated or recurring conduct, incidents, or effects that indicate an entrenched problem rather than an isolated anomaly. In the context of systemic liability, pattern evidence is crucial because it demonstrates that harm is not due to a one-time fluke, but arises from consistent practices or policies. Legally, pattern evidence can bolster foreseeability (multiple prior incidents put an authority on notice of danger) and can also establish knowledge and causation by showing a trend. For example, if over several years a police department receives numerous complaints of excessive force disproportionately against a minority group, that pattern can be used to infer an institutional issue (like inadequate training or biased culture) – essentially proving a systemic violation (in the US, one might call it a “pattern or practice” of unconstitutional conduct). In negligence or human rights litigation, claimants often compile statistics or historical cases: e.g. multiple similar deaths in custody, a series of avoidable train accidents in the same rail network, a pattern of children suffering due to social services’ failures. Such evidence can be persuasive in showing that the institution repeatedly fell below standards, thereby rebutting any defense that a particular harm was just a random bad outcome. Pattern evidence transforms anecdote into data – it provides the courts with a broader view of how the system operates. It is, in essence, evidence of system coherence or incoherence over time. If the same type of failure happens again and again, it’s powerful proof that the harm stems from underlying system flaws (design, culture, or policy), not mere chance.

Counsel: Could you give an example where pattern evidence revealed systemic failure by a public institution?

Witness: Certainly. Consider the Windrush scandal in the UK. This was not a single case of immigration mishandling, but hundreds of cases where lawful residents (primarily of Caribbean origin who arrived decades ago) were wrongly classified as illegal immigrants. An independent review (the Windrush Lessons Learned Review by Wendy Williams, 2020) concluded that Windrush was a “profound institutional failure” by the Home Office. The pattern evidence was clear: numerous individuals – many of whom had lived and worked in the UK for a lifetime – were denied healthcare, lost jobs, or even detained and deported incorrectly. The fact that so many people were similarly mistreated over a period of years indicated a systemic problem. Indeed, the review traced the roots back to decades-old legislation and a “hostile environment” policy that had grown increasingly unyielding. This pattern showed the Home Office’s processes were consistently failing to distinguish lawful residents, revealing a culture of ignorance and bureaucratic inertia. The pattern evidence in Windrush served several purposes: it demonstrated foreseeability (warnings were voiced, and each new case was a red flag), it proved causation (the policy itself caused these adverse outcomes repeatedly), and it highlighted a breach of duty (the government’s duty to treat citizens lawfully and fairly was breached en masse). Another example: in the field of child protection, the Rotherham abuse scandal (1997–2013) saw around 1,400 children sexually exploited while authorities systematically failed to intervene. The subsequent Jay Report documented how police and social services ignored or dismissed a pattern of reports and clear signs of organized abuse, year after year. The recurrence of identical failures – lost reports, victims not believed, perpetrators not prosecuted – across many cases revealed an institutional pattern of neglect and disbelief towards vulnerable girls. That pattern evidence was instrumental in labeling it an institutional failing, rather than just a series of unrelated errors. Pattern evidence essentially allows the fact-finder to say, “This keeps happening, therefore the system as a whole is culpable.” It converts isolated episodes into a narrative of ongoing practice. In doing so, it legally underpins arguments that an entity has a policy or custom that causes harm (in §1983 civil rights litigation in the U.S., for instance, pattern evidence is used to establish municipal liability under Monell). In summary, pattern evidence can turn what might seem like anecdotal complaints into a compelling demonstration of systemic incoherence – a repeated breach that cries out for legal remedy.

Counsel: How does pattern evidence intersect with the metaphysical argument that harm persists due to “institutional design, cultural inertia, failure to evolve, and fragmented foundations”?

Witness: Pattern evidence is practically the empirical backbone of that metaphysical argument. When we observe a pattern of harm, it suggests that the cause is baked into the system’s design or culture. For example, if every year a certain prison reports multiple suicides under similar conditions, one infers that something in the prison system (design of cells, training of staff, mental health provision) is fundamentally flawed or slow to change – in other words, institutional inertia or a cultural blind spot is perpetuating the harm. It shows a failure to evolve because the same mistakes repeat despite presumably learning opportunities. Likewise, fragmented foundations – say, a decentralised healthcare system where communication failures recur – will generate a pattern of mishaps (patients falling through cracks routinely). By presenting those patterns statistically or through case compilations, an expert can argue that these are not independent failures but the system’s signature. Courts and inquiries are moved by such evidence: it paints a picture of an organization that by its very mode of operation harms people. In legal reasoning, this supports findings of systemic negligence, institutional discrimination, or organizational recklessness. It aligns with the notion that the whole is at fault, not just the parts. Pattern evidence, therefore, transforms the metaphysical critique of institutional wrongs into concrete facts and figures that meet legal standards of proof.

Threshold 6: Failure to Prevent

Counsel: What do we mean by failure to prevent in a legal liability sense? Is failing to prevent harm itself a basis for liability?

Witness: Failure to prevent refers to situations where an entity had the capacity and opportunity to avert a harm, knew (or should have known) about the risk, yet did not take reasonable steps to stop it. Traditionally, common law is cautious about pure omissions – one is not usually liable for failing to act unless there is a duty to act (for example, due to a special relationship or because one has created the danger). However, when a duty of care or a statutory obligation does exist, failing to prevent a known harm is a quintessential breach of that duty. Modern legal frameworks increasingly recognize “failure to prevent” as an actionable wrong, especially for organizations. For instance, in the corporate realm, UK law has created specific offences like “failure to prevent bribery” (under the Bribery Act 2010) and has proposals for a “failure to prevent economic crime” – these impose liability on companies for omissions in stopping unlawful acts by associated persons. In negligence and human rights law, failure to prevent is essentially the flip side of foreseeability and duty: if an authority *foresees a risk and has a duty to address it, doing nothing can be negligent. A vivid way this enters legal proceedings is through coroner inquests and public inquiries. Coroners in Article 2 inquests (right-to-life cases) are tasked with identifying not just how a death occurred but how future deaths can be prevented. They often issue Prevention of Future Deaths reports when they find that authorities failed to take preventive measures that might have averted the fatality. If those recommendations are ignored and a similar tragedy occurs, that prior omission is powerful evidence of negligence. So, in summary, “failure to prevent” can ground liability when there was a clear opportunity or mandate to act for safety and that opportunity was squandered.

Counsel: How does this play out with real-world examples? Can you illustrate a scenario where an institution’s failure to prevent recurring harm led to legal or public condemnation?

Witness: A compelling example is the sequence of events linking the Lakanal House fire (2009) to the Grenfell Tower fire (2017) in London, which we touched on earlier. After the Lakanal House tragedy, a coroner issued formal recommendations for the government to improve fire safety regulations, especially regarding exterior cladding and the “stay put” advice in high-rises. These recommendations were effectively a roadmap to prevent another similar disaster. The government’s failure to act on those recommendations – essentially a failure to prevent a known risk – has been heavily scrutinized. Michael Mansfield QC, representing Grenfell bereaved families, argued that the failure to implement the coroner’s post-Lakanal safety measures directly paved the way for Grenfell, calling it an unforgivable omission. Indeed, the fact that the same type of cladding-related fire spread vertically and rapidly in both buildings is evidence that nothing was done to prevent a repeat catastrophe. This omission is likely to feature in any legal accountability for Grenfell: it’s easier to prove negligence when you can show the defendant was explicitly warned and still did nothing. Another domain: the criminal justice system’s handling of serial offenses. In cases of serial domestic violence or child exploitation, inquiries often find that authorities had multiple prior warnings or incidents that, if properly followed up, could have prevented later harm. For example, the child sexual exploitation scandal in Rotherham saw police and social services disregarding reports and failing to intervene over a decade. Each missed intervention was a failure to prevent ongoing abuse. When exposed, this led to findings that the agencies breached their duties by omission – they had legal duties to protect children and ample information, yet systematically failed to prevent the continuing crimes. Similarly, consider public health: the UK’s handling of the COVID-19 pandemic is under examination, with questions about whether earlier preventative actions (like lockdowns, border controls, or stockpiling PPE) should have been taken given what was known from other countries. A failure to take timely preventive steps, despite clear warnings, could be framed as negligent if it significantly worsened outcomes. From a legal tone perspective, these scenarios underscore that inaction in the face of foreseeable harm is actionable. It also aligns with the moral expectation that governments and institutions exist, in large part, to prevent harm to the public. When they demonstrably fail at that fundamental charge – especially after being alerted – they open themselves to liability and public censure.

Counsel: Is there evidence that systemic failures to implement recommendations or lessons-learned contribute to recurring harm?

Witness: Yes, and this is a critical point. Time and again, we see inquiries lament that lessons from past tragedies were not implemented, resulting in history repeating itself. A 2020 report by the legal charity JUSTICE titled “When Things Go Wrong” observed that there is a “lack of formal implementation and oversight” after inquests or inquiries, which makes the likelihood of future prevention limited. In plain terms, many recommendations are made to prevent future harm, but no one ensures they are carried out. This systemic failure of follow-through is itself a form of negligence on a grand scale. The Hillsborough disaster (a 1989 stadium tragedy) led to safety recommendations that arguably were not fully heeded before later crowd safety incidents; the Marchioness riverboat disaster (1989) led to recommendations on emergency exits and rescue equipment, some of which were delayed – only for similar issues to be noted in later incidents. Each time an inquiry says “lessons will be learned,” but if institutions do not institute real changes, they have failed to prevent the next foreseeable tragedy. In legal arguments, such as those made in the Grenfell Inquiry, counsel have explicitly drawn links between ignored recommendations (a form of failing to prevent) and subsequent loss of life. The pattern can itself be used as evidence: if it can be shown that an agency has a history of shelving reports or not acting on known deficiencies, plaintiffs may argue that this institutional habit of inaction constitutes gross negligence or recklessness. It demonstrates a willful blindness or systemic inertia in the face of known dangers. In sum, the failure to prevent is often the last link in the chain of systemic liability – it shows that not only did something go wrong, but that those in power had chances to stop it and did not. Legally and rhetorically, that is a damning assertion because it offends both the duty of care and the public’s trust.

Threshold 7: Knowledge Suppression / Information Failure

Counsel: Could you define knowledge suppression or information failure in this context? How does concealing or mishandling information factor into institutional liability?

Witness: Knowledge suppression refers to situations where an entity intentionally hides, downplays, or fails to disseminate important information about risks or harms. Information failure is a broader term that can include poor record-keeping, lack of data collection, or breakdowns in communication that result in critical knowledge not reaching the right people. In legal terms, these are serious because they undercut accountability and can themselves be evidence of negligence or even malfeasance. When an institution suppresses knowledge of a hazard – for example, a government agency burying a report about toxic pollution – it not only potentially violates duties to warn or protect the public, but it also demonstrates consciousness of guilt or indifference. Courts and inquiries treat such behavior harshly. It often transforms a case from mere negligence into something approaching recklessness or willful misconduct. Moreover, if knowledge was suppressed internally, it means decision-makers knew of the risk (foreseeability) and chose to do nothing or to hide it. This can practically prove the foreseeability and breach elements in one stroke. Information failures, like failing to share risk data with relevant departments, can also create liability – for instance, if a health authority had data on a spike in patient deaths but leadership never reviewed or acted on it due to internal silos, that is a systemic information failure leading to harm. In sum, knowledge suppression and information failures are about a breakdown in the flow of truth, whether deliberate or negligent, which results in harm that could have been mitigated with transparency or proper communication.

Counsel: Do we have examples of institutions suppressing knowledge or failing to share information, and what were the consequences?

Witness: Unfortunately, there are many. One clear instance is the behavior of the UK’s Department for Work and Pensions (DWP) concerning the link between disability benefit assessments and suicide. Academic researchers published “hugely alarming” findings in 2015 that the government’s new Work Capability Assessment (WCA) was associated with an increase of about 600 suicides in just three years. Instead of acting on this information, the DWP ignored the researchers – it neither contacted them nor adjusted its policies. In fact, evidence later emerged (through Disability News Service investigations and Parliamentary inquiries) that DWP repeatedly ignored and covered up internal warnings about the safety of its disability benefit system over the last decade. Internal reviews flagged that certain vulnerable claimants were at risk, coroners sent the department prevention of future death warnings, yet this knowledge was not made public or properly acted upon. This suppression and opacity meant harmful practices continued, arguably leading to more tragedies. A National Audit Office report in 2020 highlighted that the DWP even blocked attempts by a Parliamentary committee chair to get data on suicide cases, refusing disclosure on spurious grounds until the watchdog intervened. The consequence of this suppression was both continued loss of life and a potential grounds for liability: it shows the DWP knew its processes could kill and chose not to inform or reform – a strong indicator of breach of duty and indifference to human life. Another notorious example: the Hillsborough disaster. After the 1989 stadium crush that killed 96 people, South Yorkshire Police officials suppressed and altered evidence to deflect blame. Officers’ statements were edited to remove criticisms of police conduct, and a false narrative was promoted (blaming fans). This cover-up, which lasted decades, was itself a grievous wrong. When uncovered by the Hillsborough Independent Panel in 2012, it demonstrated that authorities had concealed critical truths, delaying justice and compounding the victims’ families’ suffering. The legal impact was profound: the inquest’s determinations and subsequent prosecutions were influenced by the fact that there had been a concerted effort to suppress knowledge of safety failings. It exemplifies how knowledge suppression can almost become a separate offense – in Hillsborough, it led to charges of perverting the course of justice (though those prosecutions faced their own hurdles). In more systemic terms, consider the Windrush scandal again. The Lessons Learned Review found that the Home Office showed “ignorance and thoughtlessness” on racial issues, to the point of forgetting its own history – effectively losing institutional knowledge of the Windrush generation’s legal status. Additionally, Williams noted that “warning signs and messages about the hostile environment policy were not heeded… Warnings by external stakeholders, individuals and organisations were not given enough consideration”. In other words, information that should have corrected the Home Office’s course was either ignored or not properly communicated up the chain. This information failure had dire results: British citizens were wrongly deported or denied rights. From a liability perspective, the fact that external warnings were disregarded is damning; it shows the institution was presented with knowledge of harm and effectively suppressed its significance. Finally, in the realm of corporate malfeasance, one can point to how Big Tobacco suppressed research on the dangers of smoking, or how oil companies like Exxon knew about climate change decades ago yet funded climate denial. Exxon’s internal scientists accurately predicted global warming in the 1970s, but the company spent subsequent years publicly sowing doubt and lobbying against emissions cuts. This is knowledge suppression on a global scale. Though legal accountability for climate change is still evolving, such evidence is increasingly used in court to show that companies acted in bad faith – they foresaw harm to the public and actively concealed it. In all these examples, the through-line is clear: institutions that hide or ignore critical information about harm become authors of that harm. Legally, this can transform negligence into something more egregious (gross negligence or willfulness), supporting claims for exemplary damages or human rights violations due to the callous disregard for transparency and safety.

Counsel: From a systemic perspective, what effect does information failure have on the coherence of safety systems?

Witness: Information is the lifeblood of any safety or regulatory system. When information flow is stifled – whether by deliberate suppression or by systemic disarray – the system operates blindly, and preventable risks materialize into disasters. A coherent system depends on feedback loops: front-line reports of hazards must reach policy-makers; expert analyses must inform practice; past mistakes must guide future precautions. If knowledge is suppressed or lost, those feedback loops break. The result is an incoherent system – one that doesn’t learn, doesn’t correct itself, and thus perpetuates harm. A telling observation in many inquiries is that “the tragedy was that warnings were ignored”. Information failures thus often lie at the root of systemic failures. For instance, the Mid Staffordshire hospital inquiry noted that even though many staff and patients’ families raised alarms about poor care, those alarms were not adequately recorded, escalated, or acted upon. The organizational culture did not welcome bad news, so it essentially suppressed knowledge of its own failings, leading to ongoing patient deaths. The Justice working party report I mentioned also highlighted that without oversight of implementing recommendations (an information tracking failure), future prevention is unlikely. So if we zoom out: knowledge suppression and information failures are often the connective tissue between one disaster and the next. They explain why institutions “don’t get it” until it’s too late. In legal terms, showing that an institution had the information to act and chose not to is one of the most compelling ways to establish that any later professed ignorance was willful ignorance. This can pierce defenses and immunities; for example, public bodies sometimes claim they weren’t aware of the risk (a defense against foreseeability), but if documents surface that the risk was flagged and buried, that defense crumbles. Therefore, addressing this threshold is about proving that the system had knowledge at its disposal and failed to use it, aligning perfectly with arguments of systemic negligence or even systemic intent.

Threshold 8: Disproportionate Impact

Counsel: How does the law view disproportionate impact? Are institutions held liable if their actions or failures harm certain groups more than others?

Witness: Disproportionate impact refers to policies or failures that, while perhaps neutral on their face, in practice affect one group far more severely than others. In legal arenas, this concept appears in equality and human rights law under terms like “indirect discrimination” or violation of equal protection. If a public authority’s systemic failure causes a particular class of persons – say, a racial minority, women, the disabled, or the poor – to suffer outsized harm, that disparity can be evidence of illegality or at least a breach of public law duties. The UK Equality Act 2010, for example, requires public bodies to have “due regard” to the need to avoid discrimination and promote equality (the Public Sector Equality Duty). Ignoring the disproportionate impacts of a decision can mean that duty was breached. In human rights law, Article 14 of the European Convention on Human Rights prohibits discriminatory impact in the enjoyment of rights – so if the state’s omission (like failing to provide adequate housing) affects, for instance, immigrants or disabled people more harshly, that could raise an Article 14 issue in conjunction with other rights. Moreover, disproportionate impact often underlines a systemic bias or structural inequality. Legally, if it is shown that an institution knew of the skewed impact and persisted, it strengthens claims of institutional mala fides or negligence. It’s also relevant in tort: consider a scenario where environmental pollution from a factory disproportionately sickens a low-income community; while tort law doesn’t directly account for the social status of victims, evidence that the harm was concentrated may indicate the defendant targeted a less powerful neighborhood (which could support punitive damages or establish foreseeability if the defendant assumed that group couldn’t fight back). In summary, disproportionate impact is a lens that reveals who is bearing the brunt of systemic failure. If it’s consistently the same vulnerable group, the law (especially via human rights and equality mechanisms) takes note and can deem the situation unlawful or necessitating a remedy.

Counsel: What evidence do we have of disproportionate impact in the context of systemic failures? Could you provide examples, particularly focusing on the UK or global instances?

Witness: The austerity era in the UK provides a wealth of evidence on disproportionate impact. Professor Philip Alston, the UN Special Rapporteur on Extreme Poverty, conducted a fact-finding visit to the UK in 2018 and found that the burden of austerity was not shared equally. In his report, Alston stated bluntly: “The costs of austerity have fallen disproportionately upon the poor, women, racial and ethnic minorities, children, single parents, and people with disabilities.”. In other words, the most vulnerable and marginalized communities were hit far harder by cuts to services and welfare. He noted, for example, that changes to taxes and benefits since 2010 were systematically disadvantaging families with disabled members, and that poverty rates (especially child poverty) were soaring — a state of affairs he called not just a disgrace but “a social calamity”. Legally, these findings imply potential breaches of international commitments: indeed, Alston concluded that austerity Britain was in breach of four UN human rights agreements – relating to women’s rights, children’s rights, disability rights, and socio-economic rights. He remarked that if a group of misogynists had set out to design a system to disadvantage women, “they would not have come up with too many ideas that are not already in place” – highlighting how single mothers and female pensioners were disproportionately impoverished by policy choices. This kind of evidence can be marshaled in court or tribunals to show that the government failed its Public Sector Equality Duty by not considering these impacts, or even violated substantive rights (e.g., the rights of the child, or Article 3 of the UN Convention on the Rights of Persons with Disabilities which the UN committee famously said the UK had gravely breached). Another instance: the Windrush scandal had an obviously disproportionate impact on people of Caribbean descent (and other Commonwealth immigrants of color). While not designed to target that group, the hostile environment policy’s requirements (proof of status for jobs, healthcare, etc.) disproportionately affected those communities due to historical circumstances (many had not been given documents). Wendy Williams’ review stops short of labeling it outright “institutional racism,” but it strongly implies that had the people affected been white and UK-born, the institutional obliviousness would not have persisted as it did. She found serious “institutional ignorance and thoughtlessness” regarding race. This disproportionate racial impact is evidence of a systemic cultural problem in the Home Office. It also aligns with the definition of institutional racism given by Sir William Macpherson in the Stephen Lawrence Inquiry – namely, processes that, even if not intended to discriminate, actually result in inequitable outcomes for minority groups. In environmental regulation, globally we see that poor and marginalized communities suffer disproportionate impacts of pollution and climate change. For example, air pollution in the UK has been found to have worse effects on deprived and ethnically diverse areas (take London: boroughs with higher minority populations have higher exposure to illegal air pollutant levels). The case of Ella Adoo-Kissi-Debrah, a 9-year-old girl in London, was instructive: a coroner ruled in 2020 that air pollution (from traffic in a deprived area) was a cause of her fatal asthma attack – the first time in the UK that air pollution was listed as a cause of death. It underscores that government failure to ensure clean air disproportionately endangers children and those in high-traffic, low-income neighborhoods. Disproportionate impact often reveals itself in statistics: if one can show, for instance, that cuts to legal aid led to a majority of women domestic violence survivors being unable to get protection orders, or that closure of libraries mainly hurt rural poor communities, those are disparities that matter. In litigation, such disparities can be evidence of negligence in the duty to mitigate harm for protected groups. Under the Human Rights Act 1998, if a state measure or failing impacts one group’s enjoyment of a right more than another’s, the state may have to justify it under Article 14 ECHR – and often they cannot. Thus, disproportionate impact can transform a case: it moves it from the realm of pure accident into the realm of structural injustice. It provides courts a tangible sign that something is fundamentally unjust about the status quo, often prompting a stronger remedy or at least a moral finding against the perpetrator.

Counsel: It sounds like disproportionate impact is both a diagnostic and a legal trigger. How might a courtroom use such evidence in argument?

Witness: A courtroom (especially in a high-level inquiry or a human rights case) would use disproportionate impact evidence to argue that the harm engages constitutional or human rights concerns beyond a normal tort. For example, counsel might say: “Not only did the policy cause harm, but it did so in a way that grossly disproportionately affected already disadvantaged groups. This offends the principle of substantive equality.” This could bolster a claim that the state breached the Article 2 right to life in a discriminatory manner (if say, police failings systematically leave women unprotected from a known serial killer – a hypothetical echo of the Opuz v. Turkey case, where the state was found to violate Article 2 and 14 by not protecting a woman from domestic violence due to a climate of gender-based passivity). In domestic judicial review, if an impact assessment wasn’t done or was done and ignored, showing the dire disparate outcomes can lead a court to declare the decision unlawful or order mitigations. From the metaphysical viewpoint the user mentioned – harms perpetuated by institutional design or inertia – disproportionate impacts are often a sign of cultural inertia or bias. It indicates the system didn’t evolve to correct an imbalance. In a trial or hearing, an expert (like myself in this scenario) might be asked: “Who suffered the most, and what does that tell us about the system’s values?” And I would respond with the kind of evidence above: e.g., “The poor, women, and disabled have borne the brunt, showing that the system implicitly devalues those groups’ well-being, making the failures not only negligent but inequitable.” This frames the liability in a broader social context that judges are increasingly sensitive to, especially when human rights and equality norms are part of the applicable law. Ultimately, disproportionate impact evidence can compel a fact-finder to recognize that remedying the harm isn’t just about compensating individuals – it’s about reforming the system to address entrenched inequalities.

Threshold 9: International Standards

Counsel: How do international standards come into play when assessing systemic liability?

Witness: International standards serve as benchmarks for state and institutional conduct. They can be hard law (treaties, EU directives, etc.) or soft law (guidelines, UN recommendations). When a country has committed to certain international obligations – say, under a UN convention or European law – failure to meet those standards can indicate a breach of duty or even give rise to direct legal action if the standard is binding. For example, the European Union’s regulations often set measurable targets (like air quality limits, safety requirements, human rights protections). If a state consistently falls short of those targets, it’s evidence of systemic failure in implementation. International human rights standards (like the right to life, to health, to adequate housing) create a yardstick: if systemic harm is occurring, one asks, does this breach the state’s obligations under those rights? If yes, the liability argument gains normative force – it’s not just domestic negligence, it’s a violation of the social contract the state has with the international community and its own citizens. In UK law, international standards can influence interpretation or impose duties directly (for instance, as long as the UK was under EU law, EU directives on environment had direct effect and allowed citizens to challenge the government’s failures). Now, even post-Brexit, the UK remains bound by many international treaties (like the European Convention on Human Rights, albeit through the Human Rights Act). A systemic failure that violates an Article of the ECHR (e.g. Article 2 on right to life, Article 8 on private life in environmental context, or Article 3 on inhumane treatment in a prison context) will result in the state being held liable in Strasbourg if not remedied domestically. International standards also include things like the Paris Climate Agreement – while largely non-justiciable directly, courts in some countries have used it to judge domestic climate action (e.g. the Urgenda case in the Netherlands). To sum up, international standards matter because they transform what might be seen as policy lapses into legal breaches. They reflect a consensus on minimum acceptable behavior. If a public institution’s systemic incoherence means it lags behind those minima, that’s strong evidence of liability and a call for reform.

Counsel: Can you give concrete instances where international standards exposed or confirmed systemic failures by governments or institutions?

Witness: One prominent instance is the UK’s violation of EU air quality standards. The EU Ambient Air Quality Directive set legal limits on pollutants like NO₂ to protect public health. For years, the UK government failed to meet those limits in numerous urban areas. ClientEarth, an NGO, brought a series of judicial review cases against the government. In 2015, the UK Supreme Court declared that Britain was in breach of its legal duty under EU law to achieve nitrogen dioxide limits. The Supreme Court issued a mandatory order compelling the government to produce new compliance plans. Here, the international (EU) standard was the yardstick: persistent exceedance of pollution limits (a systemic failure in environmental regulation) directly translated into legal liability. It demonstrated that the government’s approach to air pollution was systemically incoherent with its legal obligations, literally unlawful until corrected. Another example: The United Nations Committee on the Rights of Persons with Disabilities (CRPD) conducted an inquiry into the UK in 2016. It concluded that the UK’s austerity-driven welfare reforms amounted to “grave and systematic violations” of disabled persons’ rights. This is an incredibly strong statement by an international body – effectively saying that the system of social support had crossed the threshold of mere policy choice into the terrain of rights abuse. While the CRPD Committee’s findings are not directly enforceable like a court judgment, they carry moral and persuasive authority. They bolster domestic claimants’ cases by showing that international experts see the state’s behavior as falling below minimum standards of decency and care. Alston’s report, which I discussed, similarly said austerity Britain was violating multiple international agreements. In the corporate sphere, consider the Bhopal disaster of 1984 (the Union Carbide gas leak in India) – in its aftermath, international environmental and industrial safety standards (like those by the International Labour Organization on hazardous industries) were invoked to critique Union Carbide’s safety protocols. While Bhopal litigation was complex and mostly in Indian/U.S. courts, the shadow of international standards (for example, the baseline safety measures any chemical plant should have per global guidelines) highlighted how egregiously the company’s Indian subsidiary fell short, indicating a systemic corporate failure to adhere to known best practices. Similarly, after the Rana Plaza factory collapse in Bangladesh (2013), international labor standards and building codes were used to pressure global garment brands and local authorities, exposing that the building violated basic safety norms. Legally, it spurred new international accords on fire and building safety in the garment industry, illustrating how falling below international standards can catalyze liability and reform. Back to the UK: another area is prisoner rights. The European Committee for the Prevention of Torture (CPT) sets standards for conditions of detention. Investigative reports (both domestic and international) have found that some UK prisons are dangerously overcrowded, violent, and squalid – arguably in violation of Article 3 ECHR (inhuman or degrading treatment). For instance, the 2018 case of Murphy v. UK in the European Court of Human Rights found that the failure to provide an adequately prompt parole hearing for a prisoner was a violation; while not exactly conditions-based, it shows how systemic delays can breach international human rights requirements. Where a pattern of inmate suicides or violence due to neglect emerges, claimants have invoked Article 2 or Article 3, saying the state systematically fails to uphold basic standards set by the Convention. Often the mere invocation of international scrutiny pushes governments to address systemic issues (to avoid the embarrassment of condemnation abroad). The key point is that international standards often distill the lessons and expectations from around the world. If an institution’s conduct is incoherent with those, it’s a red flag that legally and morally, something is awry. Courts may not always directly enforce every standard, but they serve as an external measure of how far off the mark the system is. It strengthens the case that reform or accountability is not only a local demand but a global expectation.

Counsel: In framing an argument for systemic liability, how would an advocate use international standards in court?

Witness: An advocate would likely use international standards to buttress claims of negligence or rights violations by showing that the defendant’s practices are not normal or acceptable when viewed against a larger context. For example, in a case about polluted water affecting communities, counsel might cite World Health Organization guidelines or treaty obligations on the right to water to say: “This level of contamination and the authorities’ failure to address it contravene the standards the UK has pledged to uphold. It is evidence of a system that’s fallen below internationally accepted levels of care.” Or take a case of a public housing failure: an advocate could reference the UN’s Right to Adequate Housing, highlighting that frequent fires or uninhabitable conditions breach those international principles, reinforcing the negligence claim. In human rights litigation, it’s even more direct – one would argue that the state’s systemic failure is a breach of Article [X] of an international convention. For instance, a failure to prevent foreseeable loss of life (like the authorities ignoring threats to kill a person, who is then murdered) would be framed as a breach of the Article 2 right to life under the ECHR, as explicated by cases like Osman and subsequent Strasbourg jurisprudence. The advocate might say: “Your Honor, this is not just a matter of domestic law – the pattern of inaction violates the United Kingdom’s international obligations, specifically the positive duty to protect life. Courts in Strasbourg have found states liable on essentially these facts, and we urge this court to likewise hold our authorities accountable to that standard.” The metaphysical aspect – arguing that “fragmented foundations” and failure to evolve are at play – can be given concrete form by showing how international bodies have repeatedly told the institution to improve (e.g., the UN Committee Against Torture might have urged reforms in detention practices, yet the state didn’t act, implying inertia against global advice). That demonstrates a kind of obstinate refusal to meet modern standards. Ultimately, invoking international standards elevates the argument: it says this isn’t just my opinion that the system failed; the global consensus, the treaties we signed, the judgments of supranational courts all confirm this failure. It adds persuasive weight and, in some cases, binding authority. It tells the court that upholding these standards is part of its role in ensuring the rule of law, and conversely, that ignoring them would place the jurisdiction outside the community of law-abiding nations. For a judge, that can be a compelling prompt to find in favor of systemic accountability.

Threshold 10: Documented Attempts to Seek Remedy

Counsel: Lastly, what is the significance of documented attempts to seek remedy in evaluating systemic liability?

Witness: Documented attempts to seek remedy refers to evidence that people affected by the harm (or whistleblowers, advocates, officials) tried to complain, warn, or obtain help through official channels before the ultimate disaster or before resorting to litigation. Such attempts might include internal reports, complaint filings, petitions, letters to authorities, legal grievances, or media outreach by those suffering harm. The significance is enormous: it shows that the system had opportunities to correct itself – it was put on notice of the problems by those very people it was hurting – yet it failed to respond adequately. In legal arguments, this is a powerful indicator of systemic negligence or even deliberateness. If victims knocked on the door of the courts, agencies, or regulators and got no effective answer, it undercuts any defense that the institution “didn’t know” or that the harm was unavoidable. It also speaks to causation: had those early cries for help been heeded, the final harm might have been averted, so their neglect is part of the causal story. Additionally, from a duty of care perspective, once an institution is directly alerted by those at risk, one could argue a duty crystallized to address the grievance (even if one wasn’t clearly recognized before). Evidence of attempted remedies also often correlates with knowledge suppression: sometimes those attempts are ignored or buried, looping back to threshold 7. But the focus here is on the victims’ perspective – they did what they could, within the system, to get justice or safety, and the system failed them repeatedly. This often resonates strongly in courts or inquiries because it highlights the human element and fairness: people should not have to suffer harm before they’re taken seriously. If they weren’t, it points to a broken system.

Counsel: Can you share examples where victims or concerned parties sought remedy or warned of issues, and those attempts were documented yet went unaddressed?

Witness: The Grenfell Tower disaster provides perhaps one of the most tragic examples. The residents of Grenfell, long before the fire, had formed the Grenfell Action Group. They were deeply worried about fire safety and the management’s neglect. In November 2016 – eight months before the fire – resident Ed Daffarn wrote on the group’s blog, warning that “Only a catastrophic event will expose the ineptitude and incompetence of our landlord [the Kensington & Chelsea Tenant Management Organisation].”. This chilling prediction was not hidden in a drawer; it was a public blog post, effectively a plea for action. What happened? Evidence from the public inquiry shows that the TMO’s chief executive was informed of the blog and he instructed colleagues that “we should do nothing” in response. They dismissed the residents’ warning as scaremongering. There were also petitions: residents had repeatedly petitioned about fire safety issues (defective alarms, power surges, blocked exits) in 2010, 2013, 2015, and even March 2017 – just months before the tragedy. A local councilor, Judith Blakeman, relayed these fire safety concerns to the TMO and council multiple times over years. All these attempts are documented. Their being ignored is now part of the evidence of gross negligence by the housing authorities. The Grenfell Inquiry has zeroed in on this, essentially asking: how could the TMO and council brush aside the very people they were meant to protect, until it was too late? The Mid Staffordshire hospital scandal also had documented attempts: families of patients formed a group called “Cure the NHS” and campaigned about the atrocious care; many nurses and doctors internally raised complaints. One whistleblower, Helene Donnelly, gave testimony of how staff concerns were met with indifference or intimidation. Julie Bailey, who lost her mother at Stafford Hospital, was instrumental in gathering dozens of accounts and lobbying for an inquiry. Those efforts were initially brushed off by the Trust and local health authorities, which later strengthened the case that an independent inquiry (and liability) was needed – the voices of patients had been systematically ignored. In the DWP benefits context, families who lost loved ones to suicide after benefit withdrawal wrote letters to ministers, coroners issued Prevention of Future Death reports addressed to DWP, and MPs like Frank Field sought data and hearings. The fact that these approaches were rebuffed (e.g., DWP refusing to release information or properly investigate each death) shows that people were trying to get the system to correct itself and hit a brick wall. This was a factor in the NAO concluding the DWP had no effective mechanism to learn from deaths. Windrush, again, had victims writing to the Home Office about their unfair treatment; many were ignored or received inadequate replies. It took media exposure and litigation to resolve individual cases – and eventually the scandal as a whole – but by then careers were destroyed and lives uprooted. Each ignored letter or dismissed complaint now stands as evidence of institutional deafness. One Windrush victim, Paulette Wilson, actually delivered a petition to the Prime Minister after she was wrongly detained – a documented plea – yet it required a public outcry to get action. This threshold is a kind of reality check: it asks, did the system give people a fair hearing when it should have? If the record shows numerous unanswered cries for help, a court or inquiry can conclude the system wasn’t just unlucky, it was unresponsive by design. That dramatically strengthens the claim of systemic liability.

Counsel: How might an advocate leverage these documented attempts in a courtroom narrative?

Witness: An advocate will use these attempts to paint a timeline of warnings and pleas leading up to the catastrophe. It personalizes the failure – jurors or judges see the names, dates, and content of complaints that were effectively ignored. For instance, in a closing speech one might say: “Your Honor, the evidence shows the tenants didn’t sit idle. On [date], they petitioned about exposed gas pipes; on [another date], they begged for removal of flammable cladding; their councillor raised these in council meetings. All of this is in emails and minutes. Yet no meaningful action was taken. They were patronized or stonewalled until the night of June 14, 2017, when the very nightmare they predicted came true. The defendants had every chance to prevent this. Real people knocked on their door repeatedly, and were turned away. This is the paradigm of systemic negligence.” This approach does a few things: morally, it assigns blame for callousness; factually, it establishes knowledge and opportunity; legally, it satisfies elements like foreseeability, breach, and causation in a compelling way. It also resonates with judges’ and juries’ sense of justice: people should not have to scream into a void to get basic safety. If they did, the fault lies with the system that ignored them. Documented attempts and ignored remedies also feed into the argument for punitive or exemplary damages if applicable (showing a wanton disregard for citizens’ rights). In inquiries or policy proceedings, it strongly supports recommendations for overhauling complaint systems and ensuring whistleblowers are heard. In essence, this threshold takes the abstract concept of “the system knew or should have known” and gives it flesh and bones: these letters, these meetings, these petitions were the system being told the truth – and the system chose silence. For any tribunal, that is often the most damning evidence of all.

Counsel: Your Honor, that concludes the AI expert’s testimony. The ten thresholds – from foreseeability through to these ignored remedies – collectively demonstrate how we can legally and evidentially support claims of systemic liability. They show that harm is not merely the product of individual mishaps, but often the result of institutional design flaws, cultural inertia, and disregard for coherent action. Each threshold has been illustrated with real-world examples (from Grenfell to Windrush to austerity and beyond) that ground this metaphysical argument in hard evidence and legal reasoning. We submit that when all these factors are present – when harm was foreseeable, duty-bound institutions breached those duties systemically, causation is clear, patterns of failure emerge, prevention opportunities were missed, knowledge was suppressed, impacts skewed against the vulnerable, international standards flouted, and cries for help ignored – then the law can and must recognize systemic liability. The failure is not an accident; it is “by design or by default” of the system, and thus those in charge of that system should be held to account.
