The binding legal principles established are: (1) Failure to put a critical version to the employer's witness during cross-examination is fatal to the employee's case, and unchallenged evidence may become the bedrock of findings against the employee. (2) When a suspect denies possession of stolen property, he cannot offer an explanation for possession as an alternative defence once possession is successfully proven. An explanation regarding the circumstances of receipt must be preceded by at least an admission of possession. (3) To prove guilt under section 36 of the General Law Amendment Act 62 of 1955, there must be possession of stolen or suspected stolen property without giving reasonable account of possession or without reasonable cause to believe that at the time of acquiring it, it belonged to the person it was received from. (4) For the common law offense of receiving stolen property, a person must have acquired or received the stolen property knowing it to be stolen. (5) An arbitration award will not be set aside on review if it falls within the band of reasonableness as established in Sidumo, even if the reviewing court might have reached a different conclusion.
