Pioneered by late Andhra Pradesh chief minister N.T. Rama Rao around 1984, resort politics has been used by political parties in states like Karnataka, Maharashtra, Tamil Nadu and Gujarat.
Governor Vajubhai Vala gave the BJP 15 days to get a vote of confidence in the Karnataka Assembly, which means that the party has to attain the support of at last 113 MLAs in the floor test or ensure enough abstentions of Congress or JD (S) MLAs to lower the half way mark.
Both the Congress and JD (S) have won 78 and 38 seats respectively.
Congress President Rahul Gandhi tweeted on Thursday, "The BJP's irrational insistence that it will form a Govt.in Karnataka, even though it clearly doesn't have the numbers, is to make a mockery of our Constitution".
He said the BJP has 104 legislators and the governor invited Yeddyurappa to form the government in an "unconstitutional manner". "We will seek time from the President", Shivakumar told CNN-News18.
Anand Singh was originally with the BJP before he switched side to join the Congress.
The JDS chief HD Kumaraswamy said that the central government was using the Enforcement Directorate to blackmail Singh into siding with the BJP, which desperately needs eight more MLAs' support to secure the majority in the Karnataka assembly.
Arguing for the Union of India, Attorney General K.K. Venugopal said: "we don't know what happened in exchanges between Governor and Yeddyurappa, or what he has said in his letter".
Yeddyurappa now has 15 days to prove his majority in the state legislative assembly. The party is likely to march with 16 of its MLAs to the Raj Bhawan tomorrow. In 2018 election, Congress had emerged as the largest party but invited BJP to form the government. Jethmalani said that Governor's decision has caused disrespect to the constitutional office that he resides in.
