Islamabad , Pakistan ( CNN ) -- Pakistan 's all-powerful spy agency could face an unprecedented challenge from the nation 's high court after a lawyer representing seven victims urged contempt of court charges Friday . The Supreme Court had given the Inter-Services Intelligence ( ISI ) agency until midnight Friday to produce the seven men , who according to attorney Tariq Asad , were arrested without due process and injured while in custody . The ISI has also been ordered to explain the deaths of four other detainees . Asad said he filed a petition after the Supreme Court adjourned Friday 's hearing without the presence of the seven detainees . A three-judge panel gave the ISI a new Monday deadline to produce the men . `` The court wants the detainees in court today and they 're not accepting any excuses , '' said Asad . `` The court has said they have until midnight to produce the detainees , even if it means bringing them to court in a helicopter . '' The court did not spell out consequences if the ultimatum is not heeded . But the case breaks new ground in that the ISI has long been thought untouchable . Legal proceedings could expose the inner workings of the highly secretive agency like never before . On Thursday , the spy agency 's lawyer presented the court with medical certificates for four of the seven detainees to show they were hospitalized , and he asked permission from the court to present confidential letters explaining the whereabouts of the other three men , Asad said . The ISI blamed the death of detainee Abdul Saboor , 29 , on natural causes , but his mother said scars on his body prove the agency tortured and killed her son . `` He had so many marks on his body , '' Rohaifa Bibi said , pointing to numerous scars in a picture of her son 's corpse . `` When they showed me the body , he was just skin and bones . '' Saboor and his brothers made a living by printing Korans at a Lahore shop , Asad said . He said they were law-abiding but did acknowledge that all of the detainees were suspects in several militant attacks , though they were acquitted of the charges in 2010 . A lawyer for the ISI told the Supreme Court that the spy agency did detain the men for further questioning but said they were set free . The ISI denies any role in the four deaths they have been ordered to explain . Human rights groups have documented ISI-sanctioned intimidation , torture , enforced disappearances , and killings . The Asian Human Rights Commission urged Pakistan 's judiciary to prosecute those who are responsible for keeping the people under illegal custody . Otherwise , it said , the courts will be complicit . Journalist Nasir Habib contributed to this report .
