Mukta Dabholkar, a lawyer, and Hamid Dabholkar, a doctor by profession, have also requested that the probe by this special investigation team be monitored by the High Court. The petition may come up for hearing soon.
Dabholkar, a staunch rationalist and anti-superstition activist, was shot dead by unidentified assailants while on a morning walk in Pune on August 20, 2013.
After the police investigation made no headway, the case was handed over to CBI by the High Court last year in response to a PIL by former journalist Ketan Tirodkar. But the central agency too has failed to crack the case.
The bill was opposed by some political parties for being 'anti-Hindu'. However, four days after Dabholkar's murder, Maharashtra government brought it into force through an ordinance and the bill was passed by the legislature in December 2013.
Mukta and Hamid claim in the petition that their father's campaign for the bill incurred him the wrath of some people and he had received death threats.
The website of a religious organisation had displayed Dabholkar's photograph with a red cross on it. After the murder, the photograph disappeared, says the petition.
