#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the sentence of detention at the President's pleasure under section 25(2) and (3) of the Penal Code, imposed on an offender who was a child, was lawful
- 2.What sentencing order the Court should make in respect of the appellant in light of the High Court's declaration of unconstitutionality
Key legal issues
#Constitutionality of detention at the President's pleasure for child offenders
Sentencing under section 25(2) and (3) of the Penal Code, which committed the duration of a child's detention to the President's pleasure, is unconstitutional; sentencing is exclusively judicial and a child offender cannot be subjected to indefinite detention.
The Court accepted counsel's concession that the High Court in A.O.O. & 6 Others v Attorney General had declared section 25(2) and (3) of the Penal Code unconstitutional for violating Articles 53(1)(f)(i) and (ii), (2) and 160(1) of the Constitution. Although that decision was not itself on appeal before it, the Court endorsed its reasoning, stressing separation of powers in sentencing and the constitutional protection of child offenders from indefinite detention.
Appropriate sentence where an unconstitutional indefinite sentence has been served
Having served 18 years in detention from childhood with attendant mental anguish, the appellant had suffered enough; the sentence was set aside and immediate release ordered.
The Court noted the appellant was 17 at the time of the offence and under 18 at conviction, was not allowed to mitigate, and had endured 18 years of mental anguish, trauma and anxiety not knowing how long the President's pleasure would last. Concluding he had suffered more than enough for the crime, the Court set aside the sentence and ordered release forthwith unless otherwise lawfully held.
