Bangalore: In the wake of Supreme Court’s order quashing the disqualification of 11 BJP rebel MLAs and five independents, Karnataka has plunged into a constitutional crisis. Congress and JDS in Karnataka on Saturday upped the ante demanding dismissal of the B S Yeddyurappa government on the ground that it has lost majority.

They urged the Governor H R Bhardwaj to recommend to the Centre to invoke Article 356 of the Constitution and dismiss the BJP government.

The government has no moral right to continue in office as it had been reduced to a minority following withdrawal of support by some BJP MLAs in a petition submitted to the Governor on October 6, 2010, Karnataka PCC President G Parameshwara and Congress opposition leader in the Assembly Siddaramaiah alleged that the state legislature session being planned from May 16 was with ‘political intent’ and it was not aimed at debating development issues in the House.

The Governor should not accept the government's request in summoning the legislature session from May 16, they said.

They also demanded Bopaiah's resignation in the light of observations made against him by the Supreme Court.

Referring to April 9 by-polls to three constituencies, which BJP won, Siddaramaiah alleged that the victory came about due to BJP using its money and muscle power.

"Let Yeddyurappa dissolve the state assembly and go to polls. We will also fight it. If we fail to win, we will take political sanyas", the leaders said.

JDS leader H D Revanna and party state unit spokesman Y S V Datta alleged that Yeddyurappa has launched ‘horse trades’ to woo 11 MLAs, whose Assembly membership was restored by a Supreme Court order.

They urged the Governor to dismiss the government and not to accept the government request in summoning the legislature session. JDS leaders also urged Bopaiah to quit.

Meanwhile BJP spokesman V Dhanajayakumar said, "There is no crisis in BJP. All the 11 MLAs are with us. Our strength has now swelled from 109 to 120. Yeddyurappa government enjoys clear majority (in the 224 assembly)”.

The 16 legislators, whose disqualification was set aside by the court, have been in touch with party leaders, he claimed.

The Apex Court had on Friday quashed the Karnataka Assembly Speaker's controversial decision to disqualify the 16 MLAs on the eve of the no-confidence motion last year which had ensured survival of the Yeddyurappa government.
