(CNN) -- Col. Gregory Gross, the judge who will oversee the military trial of Maj. Nidal Hasan, ordered the Army psychiatrist to be forcibly shaved for his trial, according to Tyler Broadway, a spokesman at Fort Hood.
The order is likely to trigger an appeal that would further delay the case, which has dragged on now since 2009.
Hasan's attorney had filed an appeal when Gross threatened to order the shaving but the appeals court said it wouldn't issue a decision until the shaving was actually ordered. Thursday's order by Gross opens the door for that appeal.
The last time he was in court, Hasan told the judge, "Your honor, in the name of almighty Allah, I am a Muslim. I believe that my religion requires me to wear a beard."
