A World Trade Organization arbitrator has given the United States until April 3 to comply with the panel’s April 7 decision ordering the United States to cease discrimination against foreign online casinos.

Attorneys for the Office of the U.S. Trade Representative said Monday that the U.S would comply, but suggested any legislative remedy adopted by Congress isn’t likely to throw open the doors to the offshore cyber-gambling industry. If anything, they said, that door might be slammed shut even tighter.

“It is the position of the U.S. Justice Department that Internet gambling is illegal,” said trade representative attorney Bruce Hirsh.

“All we need to do to comply is to clarify” that Internet gambling prohibitions apply equally to offshore operators, he said. “We don’t need to let Antigua have access for horse racing.”

The WTO ruling last spring against the United States turned in large part on exceptions in the federal Interstate Horseracing Act.
