NEW DELHI: The battle between the Centre and the Delhi government over the alleged cricket scam intensified on Friday, following reports of Lieutenant Governor Najeeb Jung informing the home ministry that the Aam Aadmi Party government cannot legally set up an inquiry commission without the Centre’s approval.Chief Minister Arvind Kejriwal asked what the Centre had got to “hide” in the Delhi & District Cricket Association, and urged it to cooperate with the Gopal Subramaniam commission it announced to probe the matter.“Some channels are saying ‘Kejriwal’s commission illegal’. Is Modi’s raid legal then? We are not afraid of your raid, why are you afraid of enquiry commission Modi/Jaitley ji?” Kejriwal said. He asked them to “cooperate” with the inquiry, just as the Delhi government is doing with the CBI.Home ministry sources, meanwhile, said the Delhi government cannot institute an inquiry commission without getting the LG’s approval. “We will examine the recommendation made by the LG in coming days,” said a senior official.When ET sought to get their response, neither Jung nor his office responded officially to requests.Officials in the LG Secretariat, however, did not deny reports about Jung having written to the home ministry on Wednesday questioning the legality of the Delhi government ordering a Commission of Enquiry, under a 1952 law bearing the same name, without the Centre’s approval.In its official response to deny the need for such approval, the AAP cited the example of a previous commission set up by the Delhi government to probe the CNG scam, which it said had not been stopped from carrying out its probe by courts.“This action of the Hon’ble Lieutenant Governor clearly amounts to unjustified interference in the functioning of a democratically elected government; it is unconstitutional and violates the Transaction of Business Rules, 1993. This is the second instance within four months when the Hon’ble LG has unsuccessfully tried to block Delhi government’s decision to probe cases of corruption. Earlier, in August, the Hon’ble LG had sent a similar letter to the Union Ministry of Home Affairs, in which he had recommended that the commission of inquiry to probe the CNG scam be set aside,” a party statement said.It said the high court "refused to stay the proceedings of the said commission (the commission has only been asked by the Delhi High Court to restrain from using coercive methods pending proceedings).”
