#Scope of the Court's jurisdiction on a second appeal against sentence
The appeal being on sentence only, the Court could interfere only on grounds of law; no such ground was established.
Section 361(1) CPC confines a second appeal to matters of law. Sentencing is discretionary, and an appellate court interferes only where the trial court acted on wrong principles, overlooked material facts, or the sentence is manifestly excessive. The appellant, having pleaded guilty after four cautions and the sentence being that prescribed by statute, showed no basis for interference.
Whether the constitutionality of the mandatory life sentence could be raised on second appeal
No. The issue was raised for the first time on second appeal and was precluded; the Court also lacked jurisdiction to interfere with the statutory sentence.
Relying on the Supreme Court's decision in Republic v Joshua Gichuki Mwangi, where the constitutionality of a sentence was not raised before the trial court or the High Court, the litigant is precluded from raising it before the Court of Appeal. The record showed no such challenge before the High Court. Moreover, section 8(2) of the Sexual Offences Act remains valid and its mandatory sentence lawful.
