If you're talking about who determines whether people are admissible or not, it's up to the member interpreting the law, and if it involves a foreign offence, interpreting the foreign offence and seeing if it's equivalent to an offence in Canada, comparing the Canadian and foreign offences. I think that's what the point of the evidence was. With someone convicted in the United States, you compare the American offence to the Canadian offence. That's the job of the member to do that at the immigration division.
