Yes, except for the investment provisions. Of course, there is this choice a government has between whether they're going to use the WTO or a bilateral agreement.
If you're going to the WTO it has to be about a dispute that's covered by the WTO provisions. If it's one of these new provisions in TPP, for instance, then obviously you'd have to use the TPP because you can't litigate something if it's not part of the system.
