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.
