The report was submitted following the August 5 direction given by a division bench of justices Jayant Patel and Abhilasha Kumari.
The next hearing is slated for Friday when the court would review progress in the seven-year-old case. During the last hearing, the court had said, "Efforts shall be made by the SIT to try and complete the investigation, and submit progress report along with conclusion (if encounter was fake or genuine) by September 8."
"We have submitted a progress report to the high court on the Ishrat encounter case. But we are yet to finish investigations," an official associated with the matter said.
The court, during the last hearing, had also directed SIT chief R R Verma to investigate the retraction of statements by some of the key witnesses.
Ishrat, a 19-year-old college girl, along with Javed Sheikh alias Pranesh Pillai, Amjad Ali Rana and Zeeshan Johar, were allegedly killed in a police encounter on June 15, 2004. The city crime branch claimed the deceased were members of the Lashkar-e-Tayiba and were on a mission to kill Gujarat Chief Minister Narendra Modi.
The probe is being supervised by the high court, which had constituted the SIT last year to investigate genuineness of the encounter after petitions were filed by Ishrat's mother and Gopinath Pillai, father of Pranesh.
