Bangalore, May 19 (PTI): A special session of the Karnataka Assembly began on Saturday with Chief Minister B.S. Yeddyurappa set to take the floor test that would determine the fate of his three-day old government.

The session started with the singing of the national song, Vande Mataram, following which pro-tem speaker K.G. Bopaiah welcomed and congratulated the members elected to the 15th Assembly and started administering the oath to them.

Earlier, the Supreme Court, hearing the Congress-Janata Dal(Secular) alliance's petition challenging the appointment of Bopaiah as pro-tem speaker by Governor Vajubhai Vala, ordered the live telecast of proceedings of the floor test.

The Additional Solicitor General Tushar Mehta, who appeared for the Bharatiya Janata Party-led Karnataka government and the governor, said there would be a live telecast of the trust  vote. In view of his statement, the apex court said it was not necessary to go into all the prayers of the petitioners.

The Congress-JD(S) alliance in its petition has contended that the appointment of Bopaiah was contrary to the tradition of choosing the senior-most legislator for the post.

In the Assembly, Bopaiah read out the procedures to be followed during the oath taking of the members.

Yeddyurappa took the oath first, followed by Congress Legislature Party leader and his predecessor Siddaramaiah.

Then the other members started taking oath in batches of five one after the other.

The floor test is scheduled for 4pm as per the Supreme Court's Friday order that drastically reduced the 15-day window given by the governor to Yeddyurappa to prove majority.

Elections held on May 12 to 222 of the state's 224 seats resulted in a hung assembly with the BJP having 104 legislative assembly members, while the Congress won 78 seats and JD(S) 37. Polling in two seats will be held later.

The Congress-JD(S) alliance cited the support of 117 lawmakers, including one each from the Bahujan Samaj Party and the Karnataka Pragnyavantha Janatha Party, and one Independent.

The JD(S)'s effective strength will be 36 at the time of voting, as its leader H.D. Kumaraswamy has won from two seats.

This will also reduce the strength of the House to 221 and the BJP will require 111 votes for a simple majority.

At about 4pm, Yeddyurappa is expected to move the motion seeking a vote of confidence.

Earlier, Congress and JD(S) lawmakers who were staying at a hotel in Hyderabad, fearing alleged attempts of poaching by the BJP, came back to the city on Saturday morning.

As per the apex court's directions, the police have made massive security arrangements in and around the Vidhana Soudha, the seat of the state legislature, for the smooth conduct of the floor test.

Public entry to the Vidhana Soudha has been restricted, and officials and staff of the Secretariat are being allowed to enter the premises after thorough checks.

Yeddurappa was sworn in as chief minister on May 17, two days after the results were declared and the governor accepted his claim to form government.

The decision was challenged in the Supreme Court by the Congress and the JD(S) and passing interim orders on their petition, the court on Friday directed that the floor test be conducted on Saturday .

Yeddyurappa has asserted that he has “100 per cent confidence” that he would prove his majority in the Assembly.

With the BJP having only 104 seats, it remains to be seen how the party will rustle up the numbers and prove it’s majority.

Reports suggested that the BJP has reached out to Congress and JD(S)lawmakers, who are unhappy over the alliance of their parties for power, to abstain from attending the House.

The other plan is to ensure that at least seven members cross vote in BJP's favour.

Congress-JD(S) made the legal challenge against Bopaiah's choice as pro-tem speaker contending that the governor's action in appointing “a junior MLA” was “brazenly unconstitutional”.

A four-time legislative assembly member, Bopaiah was the Karnataka Assembly speaker from 2009 to 2013 and had disqualified 16 lawmakers and bailed out the then Yeddyurappa government ahead of a no-confidence vote in 2010.

The Supreme Court in 2011 had quashed Bopaiah's order disqualifying the 16 lawmakers.
