SAN DIEGO (AP) - A federal judge issued a worldwide injunction Tuesday stopping enforcement of the "don't ask, don't tell" policy, ending the military's 17-year-old ban on openly gay troops.

U.S. District Judge Virginia Phillips' landmark ruling was widely cheered by gay rights organizations that credited her with getting accomplished what President Obama and Washington politics could not.

"This order from Judge Phillips is another historic and courageous step in the right direction, a step that Congress has been noticeably slow in taking," said Alexander Nicholson, executive director of Servicemembers United and the sole named veteran plaintiff in the case along with the Log Cabin Republicans.

Servicemembers United is the nation's largest organization of gay and lesbian troops and veterans.

U.S. Department of Justice attorneys have 60 days to appeal. Legal experts say the department is under no legal obligation to do so and could let Phillips' ruling stand.

Phillips declared the law unconstitutional after a two-week nonjury trial in federal court in Riverside. She said the Log Cabin Republicans "established at trial that the Don't Ask, Don't Tell Act irreparably injures servicemembers by infringing their fundamental rights."

She said the policy violates due process rights, freedom of speech and the right to petition the government for redress of grievances guaranteed by the First Amendment.

"Furthermore, there is no adequate remedy at law to prevent the continued violation of servicemembers' rights or to compensate them for violation of their rights," Phillips said.

She said Department of Justice attorneys did not address these issues in their objection to her expected injunction.

Before issuing her order, Phillips had asked for input from Department of Justice attorneys and the Log Cabin Republicans, the gay rights group that filed the lawsuit in 2004 to stop the ban's enforcement.
