The binding legal principles established are: (1) Trial courts must properly discharge their statutory duties under sections 316-320 of the Criminal Procedure Act when dealing with special entries and further evidence applications, including considering all applications on their merits, making findings, settling terms of granted entries, and providing reports. (2) Under section 316(5), when a trial court grants an application for further evidence, it must itself receive and assess that evidence (including findings on cogency, sufficiency, demeanour and credibility) rather than delegating this to the appeal court. (3) A confession will be admissible where the accused was properly informed of constitutional rights (including right to silence and legal representation), made unequivocal responses denying inducement or influence, and the objective evidence contradicts claims of rights violations or undue influence. (4) An accused facing serious charges (particularly mandatory minimum sentences) has a right to reasonable opportunity to prepare and present mitigation evidence, including consulting expert witnesses, and refusing such postponement without proper justification constitutes a material irregularity affecting sentence. (5) For minimum sentencing under Schedule 2 based on common purpose to apply, the State must prove beyond reasonable doubt a common purpose to commit the specific scheduled offence (murder), not merely a common purpose to commit a lesser offence that results in the scheduled offence.
