Section 35(3)(o) of the Constitution does not confer an unqualified right to appeal in a technical sense, but rather requires provision for an appropriate reassessment of issues by a higher court, provided the statutory procedure is fair in all circumstances as demanded by section 35(3). The words 'appeal' and 'review' in section 35(3)(o) do not have technical meanings but should be interpreted broadly as requiring reassessment. There is no material difference between section 25(3)(h) of the interim Constitution and section 35(3)(o) of the final Constitution - the omission of the phrase 'to have recourse by way of' does not indicate an intention to create an absolute right of appeal. Sections 316 and 315(4) of the Criminal Procedure Act 51 of 1977, which require leave to appeal from High Court convictions, are constitutional because they provide for fair reassessment through a petition procedure involving at least two Supreme Court of Appeal judges, with various procedural safeguards, and preserve automatic appeal rights for certain irregularities and questions of law.
