A federal judge in California has issued an injunction halting enforcement of “don’t ask don’t tell.”

Judge Virginia Phillips on Tuesday ordered the U.S. military “immediately to suspend and discontinue any investigation, or discharge, separation, or other proceeding, that may have been commenced” under DADT.

Phillips previously ruled that DADT violates servicemembers’ rights to due process and free speech. However, she delayed issuing an injunction in the lawsuit brought by the Log Cabin Republicans.

The Department of Justice now has 60 days to appeal the decision but has not said whether it will do so. In the meantime, the DOJ could also seek a stay of the decision from the U.S. Circuit Court of Appeals for the Ninth Circuit. DOJ has no obligation to appeal the ruling and could simply allow it to stand.

“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. “While this is certainly news to be celebrated, we would also advise caution in advance of a potential stay from the Ninth Circuit. If the appellate court wishes to put itself on the right side of history, however, it will allow this sound and long-over due decision to remain in effect.”

Christian Berle, acting executive director of Log Cabin Republicans, said in the wake of Phillips’ initial ruling, the injunction was the “only reasonable solution.”

“These soldiers, sailors, airmen and marines sacrifice so much in defense of our nation and our Constitution,” Berle said. “It is imperative that their constitutional freedoms be protected as well. This decision is also a victory for all who support a strong national defense. No longer will our military be compelled to discharge servicemembers with valuable skills and experience because of an archaic policy mandating irrational discrimination. The United States is stronger because of this injunction, and Log Cabin Republicans is proud to have brought the case that made it possible.”

Dan Woods, one of the attorneys representing Log Cabin, said he was “extremely pleased” with the injunction.

“The order represents a complete and total victory for Log Cabin Republicans and reaffirms the constitutional rights of gays and lesbians in the military who are fighting and dying for our country,” Woods said.

Aaron Tax, legal director, Servicemembers Legal Defense Network:

“We applaud Judge Phillips for putting an immediate stop to all investigations and discharges under this unconstitutional law. As explained by the judge, this order applies across the military. This order bars the Department of Defense from enforcing or applying the ‘Don’t Ask, Don’t Tell’ law against any person under its command. We have clients under investigation and facing discharge right now. We’ll be monitoring each case over the coming days. This order will likely be appealed by the Justice Department and brought to the U.S. Court of Appeals for the 9th Circuit where her decision may well be reversed. The law still has a chance of being repealed in the lame duck session of Congress. Service members must proceed safely and should not come out at this time. Anyone in the armed forces with questions or concerns should call our hotline.”
