LeT operations commander Zakiur Rehman Lakhvi, Abdul Wajid, Mazhar Iqbal, Sadiq, Shahid Jameel Riaz, Jamil Ahmed and Younas Anjum were arrested in 2009 for their alleged role in the attacks in which 166 people were killed and over 300 injured.
They have been charged with planning, financing and executing the attacks.
The trial is taking place at a slow pace and is one of the main bones of contention in resumption of full-fledged dialogue process between India and Pakistan.
The prosecution team is upbeat about the case but the defence team held a press conference last year punching holes into evidence on record.
Pakistan has acknowledged that the conspiracy behind the attacks was hatched on its soil.
India had recently handed over five key documents running into nearly 600 pages for use in the trial here so that prosecutors can proceed against the seven accused.
The documents include a certified copy of the Indian Supreme Court's judgment on the Mumbai case, depositions by two doctors who conducted the autopsy of nine slain terrorists and the chief investigating officer who probed the case, and summons to witnesses.
