HOUSTON — Fort Hood shooting suspect Maj. Nidal Hasan should be forcibly shaved of his beard before his trial begins to avoid a “distracting and disruptive sideshow” that is “flagrantly disrespecting the Army,” military prosecutors said Wednesday.

Military prosecutors, in a response to a court of appeals ruling staying Hasan’s court-martial, argue that Hasan’s refusal to follow orders to shave is not a question of religious freedom but one of decorum and authority.

“This is a direct challenge to the military judge’s authority,” prosecutors said in court documents. “… The military has long recognized the authority of the court martial to compel an accused to appear in the proper uniform to maintain the decorum of the court.”

A military appeals court stayed the trial last week after judges found that forcibly shaving Hasan, as the military trial judge Col. Gregory Gross had ordered, would violate his religious freedom.

The United States Court of Appeals for the Armed Forces — a panel of four civilian judges appointed by the president and based in Washington — issued the order at the same time Hasan was appearing in court last Wednesday at the base in central Texas. The appeals panel, the highest court in the military system, is the equivalent of a federal Circuit Court of Appeal.

Hasan, 41, a Muslim American born to Palestinian parents, had appeared in court that day with a full salt-and-pepper beard, in uniform. He is charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the November 2009 attack on the Army base. He did not have a beard when he was arrested. If convicted, he could face the death penalty.

Hasan’s defense team argued in a court filing last week that forcibly shaving their client would violate his First Amendment right to freedom of religion. Hasan, they said, “is a practicing Muslim and has recently had a premonition that his death is imminent. He does not wish to die without a beard as he believes not having a beard is a sin,” according to his petition to the appeals court.

The lawyers noted that Hasan had “discussed his premonition and reasons for growing his beard” with a member of his military defense team who is an imam and who vouched for the fact that Hasan’s refusal to shave is because of “a sincere, personal religious conviction.”

Prosecutors noted Wednesday that Hasan had previously requested a religious exemption to wear a beard, but his request was denied by superiors, who cited the need for “discipline, unit cohesion and morale.”

They also noted that “forced shaving is not a novel concept in the military. Army regulations expressly authorize non-consensual haircutting and face-shaving for recalcitrant incarcerated soldiers.”

They go on to liken forced shaving to restraints imposed on disruptive defendants in court and upheld by the U.S. Supreme Court, including binding and gagging.

“If the judge has the authority to bind and gag a disruptive accused, then certainly he has the authority to forcibly shave” Hasan, they argued.

Prosecutors also noted that the military judge gave Hasan several chances to comply with his order to shave, that Hasan was held in contempt at five hearings, fined $1,000 each time and removed from court to watch the proceedings from a trailer via closed circuit television.

“It is clear that nothing sort of forcibly shaving (Hasan) will end the disruption,” they wrote.

In the end, prosecutors argued, forcibly shaving Hasan is the best remedy to address his “fundamental rights to attend trial; to confront the witnesses against him; and to communicate with his defense team while at the same time maintaining a full and fair proceeding by foreclosing any possible prejudice by [jury] members seeing the accused with a full beard.”

If Hasan is not forced to shave, prosecutors argue, he “injects potential error into the court martial” and the court will “run the risk that the accused will further inflame the panel to his own detriment” — laying the groundwork for an appeal.

They also note that allowing Hasan to keep the beard would set a dangerous precedent to other defendants and soldiers “that it is acceptable to be in non-compliance with judicial orders and Army regulations.”

Hasan’s court-martial was on hold Wednesday pending a ruling from the appeals court. It was not clear how soon the court will rule.

Some military legal experts said the outcome of the court-martial, and appeals, could hinge on the decision.

“It’s a test of will: Who’s going to run the show in that courtroom,” Geoffrey Corn, a retired lieutenant colonel and law professor at South Texas College of Law in Houston told the Los Angeles Times.

Corn, a former classmate of Gross, said the military judge is trying to establish a “line in the sand.”

“If he lets Hasan dictate his own course of action, the risk of losing control of Hasan and the defense increases exponentially,” he said.

“Maj. Hasan is a soldier. He has a legal duty to comply with all orders and regulations,” including uniform regulations, Corn said, noting that as a soldier, Hasan is still receiving full pay and benefits while incarcerated.

“Perhaps Maj. Hasan is going to attempt to use the court-martial as a sort of last stand on who he is and what he believes,” Corn speculated. “That’s not its function.”

If Hasan is forcibly shaved, however, Corn said prosecutors will probably try to prevent the military jury, or panel, from finding out.

“You can’t stop Hasan from talking about it if he testifies,” Corn said, but if he did, the judge could explain the reasoning behind the shaving as part of jury instructions.
