(CNN) -- A decorated flight nurse dismissed under the "don't ask, don't tell" military policy will be reinstated with the U.S. Air Force, the American Civil Liberties Union of Washington said.
The ACLU of Washington represented Maj. Margaret Witt in a 4-year-long lawsuit seeking her reinstatement.
In September, the U.S. District Court for the Western District of Washington ordered the Air Force to reinstate Witt. The court found that Witt's sexual orientation does not negatively affect unit morale or cohesion.
On Tuesday, the Justice Department appealed that ruling, but it is not seeking a stay of the order to reinstate Witt, clearing the way for her to rejoin the service.
"I am thrilled to be able to serve in the Air Force again," Witt said in statement Tuesday. "The men and women in the unit are like family members to me, and I've been waiting a long time to rejoin them."
There was no immediate Justice Department response Tuesday to a CNN request for comment.
