The binding legal principle is that in criminal prosecutions for illegal foreign currency dealing, the mere fact that accused persons are seen counting or handing over money does not, without more, establish that they were dealing in foreign currency. Where an accused's version of events (such as a legitimate business transaction) is reasonably possibly true, it must be accepted and the accused acquitted. The standard of proof beyond reasonable doubt requires actual evidence of illegal currency exchange, not mere inference from innocent acts. The absence of malice on the part of arresting officers is not a proper basis for preferring the State's version over a reasonably possibly true defence version.
