If you are wondering what's going on with the Cloves, Tuna, and COOL WTO disputes, Jamie Strawbridge has an ASIL Insight with some details on the implementation status of each. From the conclusion:
If the WTO upholds U.S. compliance steps in some or all of these cases, the United States will have navigated around fears that adverse rulings necessarily lead to weakened regulatory standards. In fact, if the U.S. approaches are affirmed, it could be said that these challenges encouraged “pro-consumer” and “pro-health” outcomes and did not lead to increased access for imports - an ironic twist that may make other WTO members think twice before mounting similar challenges under the TBT Agreement.
He also notes that: "The U.S. approach to compliance in U.S.—Tuna II (Mexico) is perhaps the most likely to survive further scrutiny." I agree with him there, although predicting how specific cases will turn out can be difficult.
(For those who don't know him, Jamie spent many years reporting on WTO disputes and other trade issues at Inside U.S. Trade. Even without a legal background, he did a great job with this. He is now a J.D. student at Georgetown Law, and I'm eager to see what he comes up with after arming himself with some actual legal knowledge!)
