ISLAMABAD, Pakistan — A special court on Friday issued a warrant for the arrest of Pervez Musharraf, the former military ruler of Pakistan, after he failed to appear in court for the proceedings in a treason case against him, lawyers said.

The court order said the warrant would take effect on March 31. It is a type known as “non-bailable,” which means that Mr. Musharraf cannot apply for bail and will be arrested if he does not show up for a court hearing that day.

“We will review the court decision and then decide whether to challenge it or not,” Faisal Chaudhry, one of the lawyers for Mr. Musharraf, told reporters after the court hearing.

Mr. Musharraf is currently in a military hospital in the neighboring garrison city of Rawalpindi and has repeatedly avoided appearing before the special court, citing medical and security concerns.
