The formulations by Gibbs C.J. and Brennan J. are suggestive of differences, but are reconcilable if refraining from making inquiry is regarded in appropriate circumstances as an example of knowledge of likelihood sufficient to establish the necessary criminal intent. However, the notion of refraining from making inquiries is sometimes erected into a doctrine of wilful blindness. In that respect it is the subject of an article by Professor Lanham. "Wilful Blindness and the Criminal Law", Criminal Law Journal, vol. 9 (1985), p. 261. In our view there are real dangers, as Professor Lanham recognizes, in seeking to apply some doctrine of wilful blindness to the criminal law and in particular to a prosecution under s. 233B(1)(b) of the Customs Act. The basic question for the jury is whether the Crown has discharged the onus of proving that the accused intended to import a prohibited import, which requires at the least knowledge of the likelihood that what is being imported is a prohibited import. If there was nothing to arouse the accused's suspicion, it is hard to see how the Crown could discharge the onus of proof. If there was evidence from which the jury might reasonably conclude that the accused's suspicions were aroused but that he deliberately refrained from making further inquiries, the jury might properly conclude in all the circumstances that he knew that the goods were likely to be prohibited imports, or where, as here, the goods were in a container, that it was likely to contain narcotic goods. But it would have done so, not by applying a doctrine of wilful blindness, but simply by treating the question as an evidentiary one - and deciding whether the Crown had proved beyond reasonable doubt that the accused intended to bring into the country a prohibited import. That approach is in accord with what was said by Brennan J. in He Kaw Teh, and is not inconsistent with what was said by Gibbs C.J."
