Introduction
In Regina v. Murray', the learned trial judge, Justice Gravely, errs in his
interpretation and application of the law of mens rea in the offence of wilfully
attempting to obstructjustice2. In view of his findings of fact and law, including the
determination that the accused knowingly and intentionally committed the actus
reus of the offence and the absence of any suggestion that he lacked awareness of
any relevant facts, there is no question in law but that Kenneth Murray was liable to
be, and actually should have been, convicted. Nonetheless, the trial judge concluded
that Murray's alleged belief, that his actions were required by his duty to his client,
raised a reasonable doubt about his intention to obstruct justice and entitled him to
be acquitted.
In his reasons for judgment, the trial judge analyzes mens rea as if there is a
colour of right defence to the offence of obstruction ofjustice. In law, however,
no such defence exists to this offence. Consequently, even if Mr. Murray did
honestly believe that he had a duty to his client not to disclose the existence of the
video tapes, that belief could not provide him with an exculpatory defence. In
Canada, mistakes of law do not excuse accused persons from responsibility for
criminal conduct in the absence of a statutory exception.' No exception exists to the
offence of obstruction of justice. Yet the Crown did not choose to appeal and
thereby signaled its acceptance of the legal analysis adopted by the trial judge. By
contrast, if the analysis proposed in this piece had been adopted, the Crown should
have prevailed at trial and, if unsuccessful at trial, would have had a right of appeal
on a question of law.
