When a regional magistrate refers a matter to the high court for sentencing under section 52 of the Criminal Law Amendment Act 105 of 1997, the high court must confirm that the conviction by the regional magistrate was in accordance with justice before proceeding to sentence. Where an accused faces a charge that falls within the minimum sentence provisions of the Criminal Law Amendment Act, the accused must be notified either through the charge sheet or otherwise during trial but before sentence that the offence falls within the Act and that the possible sentence includes life imprisonment. Failure to so advise renders it incompetent for the court to impose life imprisonment under section 51(1) of the Act. Where age is an essential element of an offence under section 51(1) read with Part I of Schedule 2 of the Criminal Law Amendment Act, there must be admissible evidence to prove the complainant's age. A medical opinion in a J88 form that is not supported by facts and where the doctor does not testify is inadequate to prove age satisfactorily, even if admitted by consent. Where a minor testifies in criminal proceedings, before administering the oath under section 162 of the CPA, the presiding officer must conduct an enquiry to satisfy himself/herself that: (a) the minor understands and appreciates the distinction between telling the truth and a lie; and (b) the minor fully understands the nature and import of giving evidence under oath. Failure to conduct such enquiry renders the minor's evidence inadmissible. Where the record is so marred by inaudibles that the court cannot determine what the proper outcome should have been, and where there are multiple serious procedural irregularities that strike at the heart of the conviction and fairness of the trial, the cumulative effect may be such that it cannot be corrected by remittal and both conviction and sentence must be set aside.
