has the basic defect. >> do you think mr. clement and this goes back to justice ginsburg question that this treaty have itself regulated individual conduct? could the treaty have them self-executing? >> i think that's an interesting question and i don't think the court needs to answer. i would take the position that if there really were self-executing treaty that try to impose criminal prohibitions and i don't think there's any treaty like that but if there were one i would say here it violates the constitution for the same basic reasons that this implementing legislation does. >> where would you find that in the constitution because there is clearly a treaty power that does not have subject matter limitations and indeed if you go back to the founding history it's clear that they thought about all kinds of subject matter limitations in james madison and others decided quite consciously not to impose them. food where would you find that limitation the constitution?
