Aafia Siddiqui, who is serving an 86-year prison sentence for shooting at U.S. agents in Afghanistan, is appealing the decision.

AP reports: Siddiqui's lawyer, Dawn Cardi, told a three-judge panel of the 2nd U.S. Circuit Court of Appeals on Friday that even though her client was judged competent to stand trial, she was so disabled by paranoid schizophrenia that the court should have taken the unusual step of barring her from testifying.

"She had no intelligent understanding of what was going on," Cardi said. "She was not rational."
