What is the test for establishing a permissive prima facie case in a sexual assault case?

[57] As stated above, in my June 19th, 2009 decision in Regina v. Martin, supra., I determined that at the close of its case, the prosecution had adduced some evidence of each essential element of the actus reus of the subject offence, upon which a reasonable jury, properly instructed could return a verdict of guilty. I therefore determined that the prosecution evidence had established a permissive prima facie case in respect of the subject charge.
