Robinson (Appellant) v The State (Respondent) (Trinidad and Tobago)

Robinson (Appellant) v The State (Respondent) (Trinidad and Tobago)

The conviction for murder was unsafe because the combination of cross-examination, prosecution speech, and the judge's summing up deprived the jury of necessary guidance on the real issue of diminished responsibility, leaving them with unresolved and misleading criticisms of the psychiatric evidence. The conviction for murder must be quashed and substituted with a conviction for manslaughter on the grounds of diminished responsibility.
