"I am thinking of approaching the Supreme Court against the JD(S) as it went back on its promise of support even after pledging unconditional support by filing sworn affidavits of its MLAs," he said addressing a convention organised to facilitate BJP members elected from the Urban Local Bodies.

Yeddyurappa, whose week-old Government collapsed on the floor of the state Assembly on November 19 following a whip issued by the JD(S) to vote against it, asked his partymen to expose the acts of "betrayal" by the former coalition partner, with which the BJP shared power for 20 months.

He said BJP would contest all the 224 seats in the coming Assembly elections and ruled out any truck with any political outfit, including the Janata Dal (United).

BJP had fought the 1999 Assembly election on seat sharing basis with the JD(U) and the experience had proved disastrous for both the parties.

Yeddyurappa came down heavily on a section of dissidents in the party and asked them to shun anti-party activities.

A compact disc on JD(S)' refusal to transfer power to BJP and bringing down of its government was released on the occasion as a campaign material in the run up to the assembly elections.
