A Pakistan court on Friday rejected extradition of Taliban leaders to Afghanistan that has been under US-led occupation for years with thousands of troops.
Taliban's top military commander, Baradar, had been captured in the Pakistani city of Karachi in a secret raid by CIA agents.
The move comes as US-led forces across the border in Afghanistan undertake one of Nato's biggest offensives against the Taliban.
Rights activist Khalid Khawaja lodged a petition in the Lahore High Court expressing concern that Baradar and other captured Taliban leaders would be extradited to the United States.
"They should not be handed over to any other country," Judge Khawaja Mohammad Sharif said as he issued notices to authorities blocking the extradition of five people including Baradar.
Khawaja said in his petition the fighters were Muslims and had been arrested in Pakistan so they should be tried under Pakistani law.
Pakistan has only confirmed the arrest of Baradar but Afghan government officials have said three other senior Taliban members, Abdul Salam, Mir Mohammad and Abdul Kabir, had recently been arrested in Pakistan.
As well as those four, the fifth person on the list included in the petition was identified as Ameer Muawiya.
US President Barack Obama plans to send 30,000 more troops to Afghanistan, where the Taliban has made a steady comeback since a US-led invasion ousted it in 2001.
