O'Grady V. Sparling - Opinion of The Court

Opinion of The Court

The opinion of the Court was written by Judson J., with Kerwin, Taschereau, Fauteux, Abbott, Martland, and Ritchie concurring.

Judson held that “the power of a provincial legislature to enact legislation for the regulation of highway traffic is undoubted”. He reaffirmed the principle that there exists a "general area" or "domain" of criminal. Thus the two governments can make law on the same matter by creating a distinction between the types of culpability.

There is a fundamental difference between the subject-matter of these two pieces of legislation which the appellant's argument does not recognize. It is a difference in kind and not merely one of degree. This difference has been recognized and emphasized in the recent writings of Glanville Williams on Criminal Law, para. 28, p. 82, and by J. W. C. Turner in the 17th edition of Kenny's Outlines of Criminal Law. I adopt as part of my reasons Turner's statement of the difference to be found at p. 34 of Kenny:

"But it should now be recognized that at common law there is no criminal liability for harm thus caused by inadvertence. This has been laid down authoritatively for manslaughter again and again. There are only two states of mind which constitute mens rea, and they are intention and recklessness. The difference between recklessness and negligence is the difference between advertence and inadvertence; they are opposed and it is a logical fallacy to suggest that recklessness is a degree of negligence. The common habit of lawyers to qualify the word "negligence" with some moral epithet such as "wicked", "gross", or "culpable" has been most unfortunate since it has inevitably led to great confusion of thought and of principle. It is equally misleading to speak of criminal negligence since this is merely to use an expression to explain itself.’’

On the facts, Judson found that there was overlap between the laws however “there is no conflict between these provisions in the sense that they are repugnant”. The provincial law extended to include “inadvertent negligence” as well as regular negligence. It was enough that “the two pieces of legislation differed both in legislative purpose and legal and practical effect” to justify both of them.
