#Key legal issues
#Power of the first appellate court to convict on a more serious charge or enhance sentence absent cross-appeal and warning
Although section 354 of the Criminal Procedure Code empowers the High Court to alter or even enhance sentence, that power may only be exercised after the appellant has been warned, or a cross-appeal filed, so the appellant can prepare; failure vitiates the enhanced conviction and sentence.
The Court of Appeal relied on its earlier decision in J.J.W v Republic, where an enhancement from seven to ten years was set aside because the prosecution neither sought enhancement nor cross-appealed, and the judge gave no warning. The rationale is fair hearing: the appellant must have the opportunity to persuade the court against enhancement. Here the DPP supported the 5-year sentence at the High Court, filed no cross-appeal, and the appellant was never warned, yet the High Court convicted him of robbery with violence and imposed the death sentence.
Fair trial rights where sentence of death imposed without fresh mitigation
Sentencing the appellant to death without taking or considering his mitigation again contravened his fair trial rights.
Because the appellant was not warned, he did not prepare to meet the robbery charge at the appeal level; the sudden conviction on the main charge and imposition of the death penalty were made without any mitigation from him being taken or considered, offending fair-hearing guarantees.
Legal principles established
#- Before the High Court may enhance a sentence or convict on a more serious charge on a first appeal, the appellant must be warned in advance (or served with a prosecution cross-appeal seeking enhancement) so as to be able to prepare and argue against it; enhancement without such warning is unlawful.
- An appellant before the High Court has a right to be informed, before the hearing of the appeal, of the danger of having the sentence enhanced if the appeal fails.
