Both Sreekumar and Sharma have, in the past, contradicted Gujarat government's version of events during the riots.
"Sharma was a part of a conspiracy with Sreekumar for fabricating evidence (against Narendra Modi government)," SIT lawyer R S Jamuar argued before metropolitan magistrate B J Ganatra.
"Argument put forward by lawyers of Zakia Jafri is that Sreekumar was tutored by G C Murmu, a government official, about the statement he was supposed to give before the Justice Nanavati Commission," he said.
"This pinpoints a larger conspiracy between Sreekumar and Sharma to fabricate evidence," the lawyer said, adding that the state government had the right to inform (government) witnesses about the statements they were supposed to give before the Nanavati Commission.
He was replying to issues raised by lawyers of Jafri, whose husband and former Congress MP Ehsan Jafri was killed during the riots. Jafri has filed a petition challenging SIT's clean chit to Modi and others over their alleged roles in facilitating riots.
