Partial defence of diminished responsibility not debarred where defendant had been voluntarily intoxicated – . The Court of Appeal, Criminal Division, held, in circumstances where the defendants had suffered from schizophrenia and killed whilst under the influence of alcohol and/or drugs, that the law did not debar someone suffering from a recognised medical condition from relying on the partial defence of diminished responsibility where voluntary intoxication had triggered the psychotic state. However, the defendant would have to nonetheless meet the criteria in s 2(1) of the Homicide Act 1957.
