PESHAWAR, Pakistan - A Pakistani court called Wednesday for the government to review an ordered retrial of a doctor who helped the U.S. search for Osama bin Laden. The retrial involves a separate case.

The tribunal's ruling called the retrial order for Shakil Afridi too ambiguous. Afridi was convicted of "conspiring against the state" in May 2012 and sentenced to 33 years in prison.

The doctor's conviction was related to allegations that he gave money and provided medical treatment to Islamic extremists, not for helping the CIA track down bin Laden. His family and the extremists denied the allegations.

The decision did not make it clear whether Afridi would be tried under regulations that govern Pakistan's tribal areas or those of the rest of the country, the court order said.

There are hardly any legal rights in tribal areas. The region is governed by regulations that mostly rely on tribal councils to decide judgments on crimes and other social issues.

Afridi ran a fake vaccination campaign to collect DNA samples, which helped the CIA track down bin Laden and his family in a compound near the Pakistani army's officers training academy in Abbottabad.

Pakistani officials were outraged by the 2011 U.S. operation that killed bin Laden, which led to international suspicion that they had been harboring al-Qaeda's founder. In their eyes, Afridi was a traitor who had collaborated with a foreign spy agency in an illegal operation on Pakistani soil.

But the doctor - who is being held in a prison - was never charged by Pakistan with helping the CIA, and U.S. officials have demanded his release.

The case has caused friction between Pakistan and the United States, complicating a relationship that Washington views as vital for fighting the Taliban and al-Qaeda, as well as negotiating an end to the war in neighboring Afghanistan.

The ordered retrial overturned Afridi's 33-year sentence. He also faces a murder charge stemming from a complaint over a teenage boy who died after the doctor performed an appendectomy in 2006.
