I'll go briefly on that issue.
It seems to me that when you're talking about the enforceability of trade agreements you're always talking some combination of law and some combination of political will. It is not difficult. We write contracts every single day that are quickly enforceable. It shouldn't be difficult in these circumstances to conceive of and draft mechanisms that can be enforced independently, judicially, transparently, and quickly to provide meaningful rights for everyone. In order to do that you need the political will of the signatories themselves, and then you need to actually come up with the mechanisms by which to do it.
Those are my thoughts on that question.
