For circumstantial evidence to support a conviction for murder, there must be objective proved facts from which guilt can be inferred, and that inference must be the only one that can fairly and reasonably be drawn from those facts. Similar fact evidence is admissible in criminal cases where it has relevance beyond showing bad character, such as proving motive, and where its probative force is sufficiently strong to warrant reception despite potential prejudice. Extra-curial confessions cannot be admitted without proof that the accused was properly warned of constitutional rights under s70 of the Constitution, including the right to legal representation and the right to remain silent. Where there is reasonable doubt as to an accused's participation in a crime, the accused must benefit from that doubt and be acquitted.
