MURDER, DIMINISHED RESPONSIBILITY, VOLUNTARY INTOXICATION, PARTIAL DEFENCE
Facts
The defendant, Dowds (D), killed his partner with a knife by inflicting 60 wounds on her. He sought to rely on the partial defence of diminished responsibility for ‘recognised medical conditions’ under s. 2(1) Homicide Act 1957 as substituted by s. 52(1) Coroners and Justice Act 2009. Dowds claimed that he was a binge drinker and was so drunk at the time of the killing that he could not remember any of it. According to him, acute intoxication amounted to ‘recognised medical condition’ under s. 2(1)(a) Homicide Act 1957 as substituted by the Coroners and Justice Act 2009. Therefore, it was capable of causing abnormality of mental functioning and thus, to found a partial defence. The judge ruled that voluntary drunkenness was not capable of founding a partial defence and did not raise the issue before the jury. Dowds was consequently convicted of a murder and appealed the decision before the Court of Appeal.
Issues
Is voluntary acute intoxication capable of founding a partial defence of diminished responsibility under s. 2(1) Homicide Act 1957?
Decision/Outcome
(1) Voluntary acute intoxication cannot by itself found a partial defence of diminished responsibility to manslaughter.
(2) S. 2(1) Homicide Act 1957 was not amended by s. 52(1) Coroners and Justice Act 2009 with the intention of going against this established practice of law.
(3) If Parliament had had such an intention, it would have made it explicit.
(4) Such an intention cannot be inferred from introducing the term ‘recognised medical condition’ into the law of diminished responsibility. The term was introduced as a response to new developments in medicine and psychiatry, not as an alteration of the law on voluntary intoxication.

This case summary accurately reflects the decision in R v Dowds [2012] EWCA Crim 281. The Court of Appeal’s ruling that voluntary acute intoxication cannot by itself found a partial defence of diminished responsibility under s. 2(1) of the Homicide Act 1957 (as amended by s. 52 of the Coroners and Justice Act 2009) remains good law. No subsequent legislation or appellate authority has overturned or materially qualified this position. The article is legally accurate and up to date. Note that the article contains a minor imprecision: the partial defence of diminished responsibility reduces liability from murder to manslaughter (not the other way around as the phrasing in point (1) could suggest), but this does not affect the core legal principles stated.
