GUANTÁNAMO BAY, Cuba — A very long-serving loss of life penalty defense lawyer for a person of the 5 adult males accused of plotting the Sept. 11, 2001, terrorist assaults has asked to be eradicated from the situation, stirring new uncertainty about when the demo may possibly start out.

It is in the end up to the demo decide to come to a decision whether the law firm, Cheryl Bormann, or any protection attorney can resign. If she is allowed to depart, the decide could be confronted with the conundrum of no matter if to slow or halt pretrial proceedings till her replacement is hired and brought up to velocity.

Or the choose could decide that the man she represents, Walid bin Attash, be tried out separately as an accused conspirator in the assaults, which killed just about 3,000 people.

Ms. Bormann very first appeared at the court docket in Could 2012 for the arraignment of Mr. bin Attash and the 4 other accused plotters, including Khalid Shaikh Mohammed, the accused mastermind of the assault. The only female capital defense lawyer on the case, she drew attention by wearing a head scarf and a black abaya, a regular robe worn by women of all ages in Saudi Arabia, in which her consumer grew up.

In time, most other ladies operating on the defense groups would observe her instance and address their hair some also wore loosefitting clothing, in what they have explained as a signal of respect for the religion of the adult men, whom they take into account to be victims of C.I.A. torture. The attire has angered some family of Sept. 11 victims, who interpreted the gesture as submissiveness to the accused terrorists.

It is not apparent why Ms. Bormann abruptly resigned. But she a short while ago filed a court docket pleading that disclosed that her “performance and conduct” have been less than investigation by the Navy Commissions Protection Corporation, the Pentagon business that delivers methods and legal professionals to armed service commissions case.

Ms. Bormann said that she could not ethically signify the prisoner although the investigation was underway and requested that hearings this month be canceled. Rather, the judge, Col. Matthew N. McCall, has postponed the start out of the hearings till March 21.

The judge gave lawyers and prosecutors until following week to file pleadings on whether he ought to launch Ms. Bormann from the circumstance.

Prior to Guantánamo, she practiced money defense in Chicago, where by she attained a track record as a dogged fighter at the Cook County general public defender’s murder job drive. She joined the war court docket bar just after Gov. Pat Quinn of Illinois abolished the death penalty in 2011, and has used the simple-spoken language of a death-penalty defender in court docket arguments to make crystal clear what is at stake.

“This is a situation where the authorities seeks to eliminate Mr. bin Attash and these other four adult males,” Ms. Bormann reminded the judge in November. Defense lawyers were urgent Colonel McCall to get the authorities to launch more details from the C.I.A.’s so-called black sites, exactly where the Sept. 11 defendants have been held and tortured right before their transfer to Guantánamo in 2006.

She has referred to prosecutors as “the federal government that wishes to eliminate him.” At just one level, protesting the confined hrs she could commit with her client, Ms. Bormann famous that “no exception is manufactured for a commissions lawyer who is defending a man where the govt needs to destroy him.”

At the heart of the situation confronting the judge is that Ms. Bormann serves as a so-termed learned counsel, a lawyer with specific capabilities and expertise in defending persons at loss of life-penalty trials. By law, each and every defendant in a capital case at Guantánamo is entitled to a realized counsel.

But no replacement is waiting in the wings, reported Brig. Gen. Jackie L. Thompson Jr. of the Army. As the chief defense counsel for army commissions, he can employ the service of lawyers for Guantánamo cases but does not have authority to hearth them. He oversaw the investigation of Ms. Bormann.

Neither Standard Thompson nor Ms. Bormann would elaborate on the substance of the investigation.

“My ongoing problem for Mr. bin Attash helps prevent me from commenting,” she mentioned.

The general claimed that he had taken no actions versus Ms. Bormann in light-weight of the investigation and that she nonetheless experienced safety clearances and whole access to her workplaces. Ms. Bormann fulfilled with the judge on Monday her team associates have twice satisfied with him individually, when with Mr. bin Attash. Typical Thompson said that the judge “has what he needs” to make your mind up no matter if to enable her go.

In his look at, he mentioned, the other lawyers on her group — a few civilians and two customers of the military services — do not qualify as uncovered counsel.

Right after the learned counsel for an additional defendant, Ramzi bin al-Shibh, obtained permission to go away the situation in 2020 because of a heart condition, the Pentagon took many months to seek the services of, fund and acquire protection clearances for the new law firm, David I. Bruck.

Mr. Bruck, a person of the nation’s top funds defenders, explained no 5-individual money case had been experimented with to verdict in the modern-day historical past of the demise penalty and questioned for 30 months to put together. The ask for was never dominated on simply because the Guantánamo court docket was closed for more than 500 times due to the fact of the coronavirus pandemic.
