The binding legal principles established are: (1) Compliance with section 163A of the Criminal Procedure and Evidence Act, requiring magistrates to inform accused persons of their right to legal representation before taking a plea, is peremptory and non-compliance vitiates the proceedings; (2) Compliance with section 271(2)(b) read with section 271(3), requiring the charge to be explained and the content of that explanation to be recorded, is mandatory and non-compliance constitutes a gross irregularity; (3) Failure to comply with these peremptory procedural provisions renders a trial unfair in contravention of section 69 of the Constitution; (4) Section 29(3) of the High Court Act cannot save proceedings that are unconstitutionally unfair because section 86(3)(e) of the Constitution prohibits legislative limitations on the right to a fair trial; (5) An unfair trial cannot stand on the basis that there has been no substantial miscarriage of justice when fundamental procedural safeguards have been violated.
