This is the last paragraph of the report:
374. The Appellate Body recommends that the Dispute Settlement Body request the United States to bring its measures, found in this Report and in the Panel Report as modified by this Report to be inconsistent with the General Agreement on Trade in Services, into conformity with its obligations under that Agreement.
The measures that they are referring to are the Wire Act, the Travel Act, and the Illegal Gambling Business Act. The US can make all of the claims they like, they still lost. And changing their horse racing laws (which they probably won't even do) won't make them a winner. As long as they offer remote gambling in this country, whether it is horse racing, lotteries, or sports, they can't claim a moral aversion to it.
Last week, at the WTO meeting in Geneva, the other parties all agreed that Antigua won and the US lost.
I haven't seen any comments by actual international trade lawyers who say the US won. All I have seen are reports that the US claimed victory. And all the US continues to do is cling to one sentence in the report that says "these laws are necessary to protect public morals." They fail to mention the big HOWEVER a few lines later. One thing the US is very skilled at is "spin."
Maybe their spin will fly in the media, but it's not going to work in front of the compliance committee of the WTO.
I should have a comprehensive legal analysis that I can post in a few days.
