For a conviction of stock theft under section 114(2)(a) of the Criminal Law (Codification and Reform) Act (Chapter 9:23), the prosecution must prove beyond reasonable doubt that the accused possessed the requisite mens rea, namely: (1) knowledge that another person is entitled to own, possess or control the livestock, or realization that there is a real risk or possibility that another person may be so entitled; and (2) intention to deprive that person permanently of ownership, possession or control, or realization of the real risk of so doing. Where an accused raises the defence of genuine mistake of fact under section 233 of the Criminal Code - that they were genuinely mistaken or ignorant as to an essential fact of the crime (in this case, the ownership of the beast) - and this defence is not controverted by the evidence, the essential elements of the offence are not proven and the accused must be acquitted. The standard of proof in criminal cases requires that guilt be established beyond reasonable doubt.
