"The post-offence conduct of the applicant in disposing of the weapon and thereafter pretending to the police that the deceased was shot by an intruder was heavily relied upon by the Crown in proof of that issue. It was evidence upon which the jury was inherently likely to rely in determining the issue. I use the term `post-offence' conduct advisedly because it extended to the disposal of the weapon, and thus, went beyond lies told to the police. In this sense, it was open to be used by the jury, as the Crown was asserting, as part of the circumstantial evidence upon which the jury could find that the gun was discharged voluntarily and with the relevant intent by the accused. It was conduct which, as the Crown said, invited the logical query: why would he act in this way if it was an accident? It has often been recognised that, while post-offence conduct is capable of being used by the jury as evidence of guilt it is also capable of being misused. The Supreme Court of Canada in the recent case of White[34] put it in these terms: `It has been recognized, however, that when evidence of post-offence conduct is introduced to support an inference of consciousness of guilt, it is highly ambiguous and susceptible to jury error. As this Court observed in Arcangioli, the danger exists that a jury may fail to take account of alternative explanations for the accused's behaviour and may mistakenly leap from such evidence to a conclusion of guilt. In particular, a jury might impute a guilty conscience to an accused who has fled or lied for an entirely innocent reason, such as panic, embarrassment or fear of false accusation.' The probative strength of post-offence conduct, such as concealment of weapon or flight, with or without `covering lies', will depend upon many factors including the circumstances in which the conduct occurred and the issue in proof of which the evidence is tendered. If it is open to be used by the jury for the purpose of drawing an inference as to the state of the accused's mind at the relevant time, the conduct will have to be assessed in the light of the probabilities. But, because such evidence is capable of being misused by the jury, the interests of a fair trial to the accused require, as I think they required in this case, a careful direction from the trial judge of the type referred to in Edwards. Such a direction should have involved a specific identification by the trial judge of the conduct being relied upon by the Crown to prove murderous intent; a direction that they could only use such conduct as proof of guilt if they were satisfied that there was no other explanation, consistent with innocence for it; and that the accused only engaged in the conduct because he knew that revelation of the truth would implicate him in the offence charged. Properly directed, the jury should also have been told that conduct such as that relied upon by the Crown could stem from reasons other than realisation by the accused of his guilt of the crime charged, what those other reasons might be, and that, if they accepted that a reason of that kind was the explanation for the conduct, they should not use the evidence as probative of guilt."
