“Don’t Ask Don’t Tell” may soon go the way of canon barrages, cavalry charges and bayonet charges. In a ruling today by a US Appellate Court, the military must prove that discharging gays improves both military readiness and unit cohesion.

From The Associated Press:

The military cannot automatically discharge people because they’re gay, a federal appeals court ruled Wednesday in the case of a decorated flight nurse who sued the Air Force over her dismissal.

The three judges from the 9th U.S. Circuit Court of Appeals did not strike down the military’s “don’t ask, don’t tell” policy. But they reinstated Maj. Margaret Witt’s lawsuit, saying the Air Force must prove that her dismissal furthered the military’s goals of troop readiness and unit cohesion.

Wednesday’s ruling led opponents of the policy to declare its days numbered. It is also the first appeals court ruling in the country that evaluated the policy through the lens of a 2003 Supreme Court decision that struck down a Texas ban on sodomy as an unconstitutional intrusion on privacy.

When gay service members have sued over their dismissals, courts historically have accepted the military’s argument that having gays in the service is generally bad for morale and can lead to sexual tension.

Under Wednesday’s ruling, military officials “need to prove that having this particular gay person in the unit really hurts morale, and the only way to improve morale is to discharge this person,” said Aaron Caplan, a staff attorney with the American Civil Liberties Union of Washington state who worked on the case.

“When the government attempts to intrude upon the personal and private lives of homosexuals, the government must advance an important governmental interest … and the intrusion must be necessary to further that interest,” wrote Judge Ronald M. Gould.

One of the judges, William C. Canby Jr., issued a partial dissent, saying that the ruling didn’t go far enough. He argued that the Air Force should have to show that the policy itself “is necessary to serve a compelling governmental interest and that it sweeps no more broadly than necessary.”

It would also appear that the military might not fight this ruling either, according to Chairman of the Joint Chiefs Admiral Mullen. It seems practicality has finally caught up with even the most conservative backwards thinking.

The next step will be to allow women to serve openly in mixed units. Maybe President Obama will work on that one now that this won’t be an issue.
