The binding legal principles established are: (1) Courts should exercise discretion liberally in granting condonation for late filing of appeals by unrepresented convicted persons who lack resources and knowledge of appellate procedures, particularly given the absence of automatic pro-deo representation on appeal; (2) Leave to appeal should be granted where an intended appeal raises arguable questions about the constitutional validity of statutory defences and where a trial court's findings on fundamental legal principles have far-reaching consequences requiring appellate consideration; (3) Provocation under s 239 of the Criminal Law (Codification & Reform) Act can never constitute a complete defence to a charge of murder, but at best reduces the crime to culpable homicide or serves as a mitigating factor; (4) Bail pending appeal will be refused where, even if the appeal succeeds, the applicant would still face a substantial term of imprisonment, making it contrary to the interests of justice to interrupt service of an otherwise appropriate sentence.
