Suicide, Speculation, and the Limits of Judicial Review – Toogood v HM Senior Coroner for Somerset

Content Warning: This article discusses a case involving suicide and findings at inquest.

Overview

In Toogood v HM Senior Coroner for Somerset [2026] EWHC 634 (Admin), the High Court (Sweeting J) dismissed a challenge to a Coroner’s conclusion of suicide, providing a clear and practical restatement of three recurring themes in inquest law:

  • The post-Maughan approach to suicide determinations;
  • The limited role of alternative hypotheses; and
  • The high threshold for judicial review of evaluative findings.

Suicide is, by its nature, often a covert act. Direct evidence of intent will frequently be absent. Inquests must therefore grapple with the extent to which intent can properly be inferred from circumstances alone.

The case is particularly important for practitioners dealing with capacity-based challenges to suicide conclusions and arguments for narrative verdicts in “uncertain intent” cases.


The Facts in Brief

The inquest concerned the death of a 72-year-old farmer who died from a close-range shotgun wound beneath the chin. The Coroner concluded the act was self-inflicted and on the balance of probabilities, it was done with intent to end life, recording a conclusion of suicide (§2-3).

The Claimant (his daughter) advanced two central alternatives of lack of capacity / psychiatric impairment and accidental weapon discharge.

She argued that these possibilities were sufficiently realistic to prevent a finding of intentional self-harm.


The Challenge

Permission proceeded on four grounds (§14):

  • The Coroner’s summing up was inaccurate and speculative;
  • The Coroner’s findings on ‘intent’ were perverse;
  • There was sufficient evidence to conclude the inquest with a narrative conclusion (shotgun injury with intent unknown);
  • There was insufficient evidence to support the Coroner’s finding that the death was intentional.

The Legal Framework (Reaffirmed)

1. Suicide after R (Maughan) v HM Senior Coroner for Oxfordshire

The Court reaffirmed the position from Maughan that suicide requires a deliberate act and an intention to end one’s life (§45). The applicable standard of proof is the balance of probabilities.

Crucially, the Court rejected any suggestion that intent is no longer required or suicide can be found without addressing it (§46).


2. No need to exclude all alternatives

At §48 and §60, the case provides a central clarification – and a clear post-Maughan correction of earlier authority. The Coroner was required to determine what probably occurred, not to eliminate every remote or speculative possibility. 

Earlier authorities requiring coroners to exclude all other explanations reflected the former criminal standard of proof. Following Maughan, that approach can no longer survive.

So the correct question is “what probably happened?”, not whether every other possibility can be ruled out.

The dividing line is between inference and speculation: the former grounded in evidence, the latter not.


3. The Wednesbury threshold remains high

Applying classic public law principles, the question is not whether another conclusion was possible, but whether no reasonable Coroner could have reached this one (§52).

The Court emphasised that evaluative judgments following the airing of the evidence are rarely disturbed, particularly in fact-sensitive inquest contexts.


Key Findings

A. Intent can be inferred from the act itself

The Court endorsed a familiar but important principle that the nature of the act may itself justify an inference of intent (§61). In many cases, inference is not merely permissible but wholly unavoidable, given the absence of direct evidence.

Here, a shotgun was discharged under the chin by an experienced firearms user. This strongly supported an inference of fatal intent.

The judgment is also a reminder that, in an appropriate case, the mode or physical mechanism of death, may itself provide sufficient evidential foundation for a safe suicide conclusion, even in the absence of direct evidence of suicidal ideation.

Coroners are not confined to direct evidence of suicidal ideation and are entitled to draw rational inferences from circumstantial evidence viewed as a whole.


B. Capacity arguments must be evidence-based

The Claimant’s case relied heavily on suggestions of hypothyroidism, medication withdrawal and alleged hallucinations.

But the Coroner found there was no clinical evidence of psychosis, the psychiatric expert found no acute disorder and the GP evidence did not support incapacity. The result was that the capacity concerns were speculative rather than evidentially grounded.

Importantly, the Court rejected any suggestion that the Coroner had to apply a Mental Capacity Act framework (§51). The Court also rejected the suggestion that the Coroner bore any formal burden of proving capacity in the manner contemplated by adversarial proceedings.


C. “Possible but not probable” is not enough

The accidental discharge theory was possible; but described by the pathologist as “stretching possibility” (§22). That was determinative. A Coroner is entitled to reject explanations that are merely conceivable but not probable.

The existence of another, speculative possibility is not enough to prevent a Coroner reaching a positive conclusion on the balance of probabilities.


D. Ordinary behaviour and absence of a note carry limited weight

The Claimant relied on the absence of a suicide note and evidence of ordinary, forward-looking behaviour (large fuel purchase, lottery ticket).

However, the absence of a suicide note, or the presence of apparently ordinary behaviour shortly before death, carries limited weight where both the physical and circumstantial evidence strongly points in the opposite direction.


E. Narrative conclusions are not a fallback

The argument for a narrative conclusion (“died from a shotgun injury with intent unknown”) failed because once the Coroner finds intent on the balance of probabilities, a narrative conclusion is inappropriate (§62).

This is a useful corrective to a common instinct to default to narrative findings in difficult cases.


F. Scope of expert evidence remains discretionary

On the procedural challenge, it was held that the psychiatric report addressed relevant issues and there was no evidence that further questioning would have changed the outcome.

The Court held the mere possibility of asking more questions to an expert does not establish unfairness (§63). Coroners are not required to pursue every theoretical possibility or call every conceivable witness in order to conduct a fair investigation.


Practical Takeaways for Practitioners

1. Post-Maughan, “alternative possibilities” carry limited weight

To resist a suicide conclusion, it is not enough to show another explanation is possible. It must be shown it is realistically probable or the Coroner’s preference for suicide is irrational.


2. Capacity arguments require proper evidential foundation

This case underlines that lay evidence of behavioural change is not enough and courts will prioritise clinical records and expert psychiatric opinion. Absent evidence of psychosis or severe cognitive impairment capacity challenges will usually fail.


3. The act itself remains powerful evidence of intent

This is particularly so where the method is inherently lethal and the deceased had relevant knowledge (e.g. firearms).


4. Judicial review remains a blunt tool

This decision is a reminder that a judicial review is not an appeal on the facts and disagreement with the Coroner’s evaluation is insufficient. The threshold remains Wednesbury irrationality – and this is a very high bar.


5. Narrative conclusions are not a compromise option

Where intent is found a short-form conclusion of suicide should follow. Practitioners should be cautious about advancing narrative conclusions as a “middle ground”.


Final Thoughts

This case illustrates the courts’ continued reluctance to interfere with a Coroner’s evaluative conclusions absent a clear public law error.

Toogood is a firm and orthodox application of post-Maughan principles, but its value lies in its clarity. It confirms that:

  • Speculation will not defeat probability;
  • Inference is often unavoidable in suicide cases;
  • Lack of capacity must be evidenced, not inferred; and
  • Coroners are entitled to draw robust inferences from evidence.

For Solicitors advising families, this case is a sobering illustration of the limits of legal challenge, even in cases where alternative explanations feel compelling.
