A death sentence may not be imposed on a person who was under 21 years of age at the time of committing the offence, in accordance with section 338(b) of the Criminal Procedure and Evidence Act. Where the death penalty is precluded by age, the court must consider an appropriate alternative sentence, taking into account the seriousness of the offence, the youthful age of the offender, their prospects for rehabilitation, and whether a definite period of imprisonment (as opposed to life imprisonment) would better serve the interests of justice and allow for reform.
