Mahkamah Agong dalam kes Mohamad Radhi bin Yaakob v. Public Prosecutor [1991] 1 CLJ (Rep) 311; [1991] 3 MLJ 169 telah menjelaskan seperti berikut: “To earn an acquittal, the court may not be convinced of the truth of the defence story or version. Raising a reasonable doubt in the guilt of the accused will suffice. It is not, however, wrong for the court to be convinced that the defence version is true, in which case the court must order an acquittal. In appropriate cases it is also not wrong for the court to conclude that the defence story is false or not convincing, but in that instance, the court must not convict until it asks a further question, that even if the court does not accept or believe the defence explanation, does it nevertheless raise a reasonable doubt as to his guilt? It is for this reason that in dealing with the defence story or explanation, the majority of judges rightly prefer to adopt straightaway the legally established 'reasonable doubt' test, rather than to delve in the 'believable and convincing' test before applying the 'reasonable doubt' test.”.
