was bought and paid for, and was to have been delivered on
Saturday night. By mistake it was not delivered that night. Next morning the purchaser sent for it, and received it. The hotel-keeper was held guilty of "opening his premises for the sale" of the liquor, on the sole ground that there had been no appropriation of the liquor, and therefore no delivery before the Sunday, and as a material part of the contract was, according to the ordinary civil law, performed on Sunday the house was opened for the purpose of sale. The contractual result was the test of the offence. In the present case, not only the delivery but the whole transaction from beginning to end took place on the Sunday.
It was suggested in this case during the argument, and is adopted by the majority of the Court, as one reason for non- application of the section, that the only act attributable to the respondent himself was the filling of the machine prior to Sunday, and that whatever took place afterwards was not his act in law, because it was said it is a primary principle in criminal law that a crime must be committed personally. Now, if that is not accurate as to more serious crimes, it cannot be so as to an offence of this kind.
As I understand the law on this point, it is this. A principal in the first degree is the actual offender. If the culpable human agent of a person instigating him is alone the actual perpetrator, he, the agent, is the principal, and the person who instigated him is not, as the last mens rea preceding the crime was not that of the instigator: R v. Manley (1). But if the intermediary, that is, the actual perpetrator, be innocent-as, for instance, a child, or a lunatic, or an unsuspecting person doing what is, on the facts as he believes them to be, a lawful act, or an animal trained for the purpose (see Kenny's Outlines of Criminal Law, p. 85)- the instigator is himself the principal, and the unlawful act is his in point of law, as it is his morally: R. v. Michael (2); R. V. Butcher (3), and other cases. And the reason such an act is held to be the act of principals is stated in R. v. Brisac (4) to be this, that innocent intermediaries are " mere instruments in their hands for that purpose."
