The prosecutors were unable to produce the documents during proceedings conducted by Judge Rana Nisar Ahmed behind closed doors at Adiala Jail in Rawalpindi, sources told PTI.
The judge had earlier directed the prosecution to provide the documents at today`s hearing.
After the prosecutors sought more time to produce the documents, the judge gave them time till June 18 and adjourned the proceedings, the sources said.
At the last hearing on May 28, the prosecutors had told the judge that the Indian government had said it will cooperate with a Pakistani judicial commission and allow it to question witnesses and officials.
The judge had asked them to substantiate their contention with any written communication sent by Indian authorities.
This matter is also expected to be taken up at the next hearing, the sources said.
