The Supreme Court today ordered that a floor test be conducted in the Karnataka Assembly tomorrow at 4 p.m. for BJP’s B.S. Yeddyurappa, who was sworn-in on Thursday as Chief Minister, to prove his majority. Yeddyurappa cannot take any major decision before the floor test, said the top court. The pro-tem Speaker will take decisions in accordance with the law on floor test. The court was hearing a petition filed by the post poll Congress-JD(S) combine against the decision of Governor Vajubhai Vala to invite the BJP to form a government. The drama started after the karnataka assembly results showed a fractured mandate with no clear majority to any party. However, BJP emerged as the single largest party with the 104 seats. Now the party has to prove the majority within 24 hours.
