I'm not a huge international policy wonk, but I don't get how these suits (this one and Omega vs. Costco) reconcile with the rules of the WTO (of which the US and Thailand are charter members). Doesn't the National Treatment Policy state that imported goods shouldn't be treated differently than locally-produced ones? And doesn't restricting the first-sale doctrine on imported good break that very rule? I'd love for someone to explain how this relates to international law that we're supposed to be following. I'm always curious abou this stuff, and I can't find anything good in my Google searches. (I realize that the WTO is rather toothless, but still.)
