The Purpose of an Inquest: What Coronial Investigations Are For (and Aren’t)

In medico-legal practice, particularly in clinical negligence and personal injury claims, the coronial inquest often represents a critical juncture. For solicitors acting on behalf of claimants, defendants, or interested parties, understanding the statutory purpose of an inquest is essential. It informs case strategy, shapes expert instruction, and clarifies the boundaries of what coronial investigations can—and cannot—achieve.

This article examines the legal and clinical frameworks governing inquests in England and Wales. It explains the statutory remit, the role of expert evidence, and the practical implications for solicitors and expert witnesses. The discussion is framed within the context of clinical negligence claims, where the findings of an inquest may influence subsequent civil proceedings, but where the coroner’s remit remains distinct from determinations of liability.

The Statutory Framework: What an Inquest Is For

Under the Coroners and Justice Act 2009, an inquest is a fact-finding inquiry conducted by a coroner to establish four key matters concerning a death:

• Who the deceased was;
• When and where the death occurred;
• How the deceased came by their death; and
• In certain cases, the particulars required by the Births and Deaths Registration Act 1953 to register the death.

The phrase “how the deceased came by their death” is interpreted narrowly. As established in R (Middleton) v West Somerset Coroner [2004], this does not extend to determining civil or criminal liability. Rather, it requires the coroner to identify the medical cause of death and, where relevant, the circumstances in which the death occurred. For example, in a case involving alleged delay in diagnosing aortic dissection, the coroner may record the immediate cause of death as “aortic rupture due to acute Type A dissection,” but will not determine whether the delay in diagnosis constituted a breach of duty.

Where a death engages Article 2 of the European Convention on Human Rights (the right to life), the inquest must adopt a broader approach. This is known as an Article 2 inquest or Middleton inquest. In such cases, the coroner is required to examine not only the immediate cause of death but also the systemic or operational failures that may have contributed to it. This may include scrutiny of NHS policies, staffing levels, or clinical pathways. However, even in Article 2 inquests, the coroner does not make findings of negligence or liability.

What an Inquest Is Not: Common Misconceptions

In clinical negligence claims, solicitors and their clients may view the inquest as an opportunity to “prove” negligence or to obtain a definitive ruling on causation. This is a fundamental misunderstanding of the coronial process. An inquest is not:

• A trial of liability. The coroner does not apply the Bolam/Bolitho test, nor does the inquest determine whether a clinician’s actions fell below the standard expected of a reasonably competent professional.
• A forum for apportioning blame. The coroner’s role is inquisitorial, not adversarial. While interested parties (including families and NHS trusts) may be represented, the process is not designed to attribute fault.
• A binding determination of causation for civil claims. Although the medical cause of death recorded on the Medical Certificate of Cause of Death (MCCD) may be persuasive in subsequent litigation, it is not conclusive. Expert evidence in civil proceedings may reach different conclusions, particularly where additional evidence emerges after the inquest.
• A substitute for a civil claim. Families may feel that the inquest provides closure, but it does not result in compensation. Separate civil proceedings are required to establish liability and quantify damages.

For solicitors, this distinction is critical. While the inquest may yield valuable evidence—such as witness statements, clinical records, or expert testimony—it should not be relied upon as the sole basis for a clinical negligence claim. The threshold for findings in an inquest is lower than in civil litigation, and the coroner’s conclusions are not subject to the same rigorous legal tests as a High Court judgment.

The Role of Expert Evidence in Inquests

Expert witnesses play a pivotal role in coronial investigations, particularly in cases involving complex clinical issues. The coroner may call upon medical experts to assist in determining the medical cause of death or to explain the clinical circumstances surrounding the death. In cases where the alleged index events span multiple specialties—for example, a cardiac arrest leading to anoxic brain injury—the coroner may instruct experts in cardiology, neurology, and intensive care to provide a comprehensive account.

For solicitors, the choice of expert is as important in inquest proceedings as it is in civil litigation. The expert must be:

• Subspecialty-matched. A general cardiologist may not be best placed to opine on the nuances of aortic dissection management, just as a general psychiatrist may lack the expertise to assess capacity in complex dementia cases. Multi-disciplinary medico-legal chambers can provide matched subspecialists, ensuring that the evidence is both clinically precise and legally robust.
• Experienced in coronial work. The format and remit of an inquest differ from civil proceedings. Experts familiar with coronial practice understand that their role is to assist the coroner in establishing facts, not to advocate for a particular outcome.
• Prepared to engage with the inquisitorial process. Unlike civil litigation, where experts may be instructed by one party, inquest experts are often called by the coroner and must maintain neutrality. They may be required to provide oral evidence at the inquest, where their testimony is subject to questioning by the coroner and interested parties.

In clinical negligence claims, the evidence given at an inquest can be highly relevant. For example, an expert’s opinion on the timing of a stroke thrombolysis window may inform both the coroner’s findings and the subsequent civil claim. However, solicitors should be aware that the scope of the expert’s remit in an inquest is narrower than in civil proceedings. The expert is not required to address breach of duty or causation in the same depth as they would in a Breach of Duty or Causation report for litigation.

Prevention of Future Deaths Reports: A Key Output

One of the most significant outcomes of an inquest is the coroner’s power to issue a Prevention of Future Deaths (PFD) report under regulation 28 of the Coroners (Investigations) Regulations 2013. Where the coroner believes that action should be taken to prevent future deaths, they may write to a relevant organisation—such as an NHS trust, a government department, or a regulatory body—setting out their concerns and requiring a response within 56 days.

For solicitors, PFD reports can be a valuable source of evidence in clinical negligence claims. They may highlight systemic failings that support allegations of breach of duty, such as:

• Inadequate staffing levels in emergency departments;
• Failure to follow NICE guidance on suspected cancer referrals (e.g., NG12);
• Deficiencies in sepsis recognition and management (e.g., failure to implement the Sepsis Six pathway); or
• Lack of adherence to fetal monitoring standards in obstetric care.

However, solicitors should exercise caution. A PFD report does not constitute a finding of negligence, nor does it bind a civil court. It is, instead, a recommendation for action. Where a PFD report identifies a systemic issue, instructing solicitors may wish to obtain expert evidence to assess whether the alleged failings meet the Bolam/Bolitho test for breach of duty.

Practical Considerations for Solicitors

For solicitors acting in clinical negligence claims where an inquest is pending or has concluded, the following considerations are key:

1. Timing of Expert Instruction

Instructing an expert early in the coronial process can be advantageous. The expert can assist in:

• Identifying gaps in the clinical records or witness evidence;
• Advising on the relevance of the coroner’s findings to a potential civil claim; and
• Preparing for the inquest, including the drafting of questions for witnesses.

However, solicitors should be mindful that the expert’s role in the inquest is distinct from their role in civil proceedings. The expert’s report for the inquest may not address breach of duty or causation in sufficient detail for a civil claim. A separate, more comprehensive report may be required for litigation.

2. Disclosure and Evidence Gathering

The coronial process can yield a wealth of evidence that may not otherwise be available. This includes:

• Witness statements from clinicians, family members, and other parties;
• Clinical records, including those from other healthcare providers not initially disclosed;
• Expert reports commissioned by the coroner; and
• Transcripts of oral evidence given at the inquest.

Solicitors should review this material carefully and consider whether additional expert evidence is required to address issues not covered by the coroner’s experts. For example, if the coroner’s expert opines on the medical cause of death but does not address the standard of care, a separate Breach of Duty report may be necessary.

3. Multi-Disciplinary Expertise

Cases involving complex clinical scenarios often require input from multiple specialties. For example:

• A death following a cardiac arrest may require expertise in cardiology (to assess the initial event), neurology (to evaluate anoxic brain injury), and intensive care (to review post-arrest management).
• A maternal death may require input from obstetrics, anaesthesia, and haematology (to assess coagulopathy management).
• A suicide in a psychiatric inpatient setting may require expertise in psychiatry (to evaluate risk assessment) and mental health law (to assess compliance with the Mental Health Act 1983).

Multi-disciplinary medico-legal chambers can provide matched subspecialists from a single panel, reducing instruction friction and ensuring coherence in the evidence. This is particularly valuable in cases where the coroner’s findings span multiple clinical domains.

4. Article 2 ECHR Considerations

Where a death engages Article 2, the inquest will adopt a broader remit. Solicitors should consider whether the case meets the threshold for an Article 2 inquest, which may include:

• Deaths in state custody or detention;
• Deaths involving allegations of systemic failure in NHS care; or
• Deaths where the state may have failed in its positive obligation to protect life.

In such cases, the coroner may scrutinise NHS policies, staffing levels, and clinical governance arrangements. Expert evidence may be required to assess whether the alleged failings meet the threshold for an Article 2 breach. For example, in a case involving delayed diagnosis of sepsis, an expert in acute medicine may be instructed to opine on whether the trust’s sepsis pathway complied with NICE guidance and whether any deficiencies contributed to the death.

Common Pitfalls and How to Avoid Them

In medico-legal practice, several recurring issues can undermine the effectiveness of inquest evidence in subsequent civil claims. Solicitors should be alert to the following:

1. Over-Reliance on the Coroner’s Findings

While the coroner’s conclusions may be persuasive, they are not binding in civil proceedings. Solicitors should not assume that the coroner’s findings on the medical cause of death or the circumstances of the death will be accepted unchallenged in a civil claim. Expert evidence in litigation may reach different conclusions, particularly where additional evidence emerges after the inquest.

2. Instructing the Wrong Subspecialty

Instructing an expert who lacks the relevant subspecialty expertise can weaken the evidence. For example:

• A general cardiologist may not be best placed to opine on the management of hypertrophic cardiomyopathy (HCM) or arrhythmogenic right ventricular cardiomyopathy (ARVC).
• A general surgeon may lack the expertise to assess the nuances of bariatric surgery complications.
• A general psychiatrist may not have the specialist knowledge required to evaluate capacity in complex dementia cases under the Mental Capacity Act 2005.

Multi-disciplinary chambers can mitigate this risk by providing subspecialty-matched experts tailored to the clinical issues in the case.

3. Failing to Distinguish Between Coronial and Civil Remits

Experts instructed in both the inquest and civil proceedings must understand the different remits of each process. An expert’s report for the inquest may focus on the medical cause of death and the circumstances of the death, but may not address breach of duty or causation in sufficient detail for a civil claim. Solicitors should ensure that the expert’s instructions are clear and that separate reports are obtained where necessary.

4. Delay in Instructing Experts

Delay in instructing experts can result in missed opportunities to gather evidence or to influence the coroner’s findings. For example, if an expert is instructed after the inquest has concluded, they may be unable to request additional disclosure or to provide input on the questions posed to witnesses. Early instruction allows the expert to engage with the coronial process and to ensure that all relevant clinical issues are addressed.

Conclusion: A Strategic Approach to Inquests in Clinical Negligence Claims

The coronial inquest is a critical process in the medico-legal landscape, but its purpose is often misunderstood. For solicitors acting in clinical negligence claims, the inquest represents an opportunity to gather evidence, to identify systemic failings, and to inform case strategy. However, it is not a substitute for civil litigation, nor does it determine liability or causation.

To maximise the value of the inquest process, solicitors should:

• Instruct the right subspecialty-matched expert early, ensuring that the expert is matched to the clinical issues in the case;
• Review the evidence gathered during the inquest and consider whether additional expert reports are required for civil proceedings;
• Be mindful of the distinct remits of the coronial and civil processes, and ensure that expert evidence addresses the specific requirements of each;
• Consider the potential for Article 2 engagement, particularly in cases involving systemic failings or state responsibility; and
• Leverage the findings of the inquest—including PFD reports—to strengthen the civil claim, while recognising the limitations of coronial evidence.

Multi-disciplinary medico-legal chambers offering subspecialty-matched expertise can be pivotal in cases of this nature. Where the clinical issues span multiple domains—such as cardiology, neurology, and psychiatry—the ability to instruct a coordinated panel of experts from a single source ensures coherence in the evidence and reduces the risk of gaps or inconsistencies. For solicitors, this means greater confidence in the strength of the evidence and a more streamlined path to resolution.
