Mr Modi, along with RK Raghavan, were members of the Supreme Court-appointed Special Investigation Team that ruled out the involvement of then Gujarat chief minister Narendra Modi in the riots that swept the state in 2002, leaving 1,000 people, mostly Muslims, dead. Their report was accepted by the top court in 2013.
