I haven't read the opinion yet myself.
What the Panel found was that blocking Antiguan companies access to the US consumers was in violation of the GATT Treaty which was signed by the US and ratified by Congress.
Under the terms of the treaty the Antiguan companies have a right to provide internet and telephone gambling services to consumers in the United States.
That's the jist of it. The US will appeal the decusion. Fortunately, the entire appelate process only takes 4-5 months.
We are certainly closer to ending the harrassment of Antiguan companies and Antiguan commerce.
