The AAP government's plans to enact the Jan Lokpal Bill in Delhi at a public venue next week faced fresh hurdles with Solicitor General Mohan Parasaran insisting that Lt Governor's prior approval is necessary.

Its key ally Congress has also toughened its opposition. Parasaran's opinion was sought by Lt Governor Najeeb Jung on the constitutionality of the Delhi Government's proposal to enact the Bill without seeking Centre's clearance. Parasaran is understood to have conveyed to him that it will be illegal if enacted without the consent.

Meanwhile, the Congress, without whose support the AAP government cannot survive, yesterday decided to oppose the Bill at the introduction stage itself.

Unfazed by criticism, the AAP government has declared that it will go ahead with enacting the law. It plans to introduce the bill in the Delhi assembly on February 13 and discuss it for two days before shifting the proceedings to a sports stadium for passage of the bill.

Information and Broadcasting Minister Manish Tewari has stressed on observing constitutional propriety. Responding to Solicitor General Mohan Parasaran’s remarks on Delhi Government's Jan Lokpal bill , he said if there is a legal or constitutional provision , it needs to be observed and followed. Mr. Tewari said, even the Aam Aadmi Party Government in Delhi has taken oath under the constitution.
