The Supreme Court on Tuesday affirmed that a "floor test is the ultimate test" to decide who is in power, and asked the Centre to consider having a trust vote in the Uttarakhand Assembly to determine whether the Harish Rawat-led Congress government has a majority. A Bench of Justices Dipak Misra and Shiva Kirti Singh called the Uttarakhand case out-of-turn in the morning and asked Attorney-General Mukul Rohatgi to seek instructions from the government on the court's suggestion to have a floor test immediately, to end the constitutional impasse. The court said it would temporarily suspend President's Rule to facilitate the floor test. Mr. Rohatgi agreed to return on Wednesday with the government's response. The court has been suggesting a floor test since the previous hearing on April 27. It had expressed its displeasure to both parties - the Centre and Mr. Rawat - for trading allegations on horse trading and the airing of a sting operation featuring the former Chief Minister allegedly discussing pay-offs.
