R v Adomako

Factual and Procedural Background

On 4 January 1987 an eye operation was performed at The Hospital in The City. During the latter part of the procedure the original anaesthetist, Doctor A, was replaced by the Appellant, who then became solely responsible for the patient’s anaesthesia. Approximately 25 minutes after the hand-over, the endotracheal tube became disconnected, cutting off the oxygen supply. Roughly 4½ minutes later an alarm on a blood-pressure monitor sounded, but the Appellant did not recognise that the patient was no longer ventilated. A cardiac arrest occurred at 11:14 a.m. and the patient died despite resuscitation efforts.

The Crown prosecuted the Appellant for manslaughter on the basis of gross negligence. Two expert witnesses (referred to here as Professor A and Professor B) characterised the standard of care as “abysmal” and “a gross dereliction of care.” The Appellant accepted civil negligence but denied criminal liability, adducing evidence from Doctor B that other physiological events could have distracted him.

A jury at first instance convicted the Appellant of manslaughter by an 11–1 majority. The Court of Appeal (Criminal Division) dismissed the ensuing appeal but certified a question of general public importance concerning the correct direction to a jury in cases of manslaughter by breach of duty. The Appellant obtained leave to appeal to the House of Lords, whose judgment of 30 June 1994 is summarised below.

Legal Issues Presented

1. Whether, in manslaughter cases involving a breach of duty outside the driving context, it is sufficient for a trial judge to direct the jury using the gross-negligence test formulated in R v Bateman and Andrews v DPP, without reference to the definition of recklessness set out in R v Lawrence.
2. Whether the Appellant’s conviction for manslaughter could stand on the basis of such a direction.

Arguments of the Parties

Appellant's Arguments

• The criminal law of involuntary manslaughter should employ a single, universally applicable test possessing clarity and coherence; the “recklessness” model adopted in R v Seymour for motor manslaughter should apply to all forms of involuntary manslaughter.
• The concept of “gross negligence” is impermissibly circular because a jury is asked, in effect, to decide whether conduct is criminal by deciding that it is criminal.
• Directions confined to gross negligence risk inconsistency and unpredictability; the more objective Lawrence definition of recklessness should therefore be mandatory.

Court's Reasoning and Analysis

Delivering the principal speech, Judge Mackay (the Lord Chancellor) held:

• Authoritative Framework: Bateman and Andrews remain the governing authorities; no subsequent decision of equal status has displaced them.
• Elements of the Offence: The jury must determine (1) the existence of a duty of care, (2) breach of that duty, (3) causation of death, and (4) whether the breach was gross. The final question hinges on whether the conduct was “so bad in all the circumstances” as to be criminal.
• Circularity Critique: While the gross-negligence test entails a degree of circularity, that characteristic is unavoidable and not fatal; attempting finer calibration would yield only “spurious precision.”
• Rejection of the Lawrence Requirement: Elaborate definitions of recklessness are unnecessary and potentially confusing when assessing gross negligence; judges may use the word “reckless” in its ordinary sense but are not obliged to do so.
• Disapproval of the Seymour Exception: Because the statutory framework underlying Seymour has been repealed, retaining a special rule for motor manslaughter would introduce unwarranted complexity.
• Summing-Up Endorsed: The trial judge’s directions correctly emphasised that only conduct falling below the minimum standard any reasonably competent doctor should meet, and doing so to a very high degree, could justify conviction.

Holding and Implications

APPEAL DISMISSED; CONVICTION AFFIRMED.

The House of Lords answered the certified question by declaring that, in manslaughter cases involving a breach of duty, a jury direction confined to the gross-negligence test of Bateman and Andrews is sufficient; reference to the technical definition of recklessness in Lawrence is unnecessary, though ordinary-language use of “reckless” remains permissible.

Practically, the judgment consolidates the law of involuntary manslaughter around a single gross-negligence standard and discontinues the separate “recklessness” framework created for motor manslaughter. Trial judges now have clearer guidance, and the decision is likely to reduce doctrinal complexity without establishing new causes of action.
