I'll say a couple of things, and I'll pass it to Daphne.
I guess the federal government certainly can use its funding power to shape national policy for universities and post-secondary institutions. That's certainly what has happened in the United States. They use the threat of withdrawal of funding as their weapon to clobber universities that do not conform to federal guidelines.
Beyond the mechanism, the issue of leadership is really important here because, as we've all been emphasizing, there's a great deal of disparity. I think every university is afraid of being picked off. As they develop their policy, all the university offices are anxious: “What if we get sued by a disgruntled student?” I'm not sure if they're as afraid of the women suing them, but I think they're certainly afraid of being sued by the men.
I think we could really use the resources and the brain power to come up with a really good model that balances the different interests that universities have, as opposed to the criminal justice system, and come up with a policy that can survive a challenge in the courts.
Last, you referred to policing and criminal prosecution. The federal government can use its federal powers to declare certain issues within federal authority. The feds could, in fact, intervene to ensure some uniformity around policing across the country, and around prosecution across the country. That argument is better developed legally by a scholar named Lucinda Vandervort at the University of Saskatchewan. I will provide the reference to that piece if you're interested in looking at it.
