The Union Cabinet on Sunday recommended President's Rule in Arunachal Pradesh after an unscheduled meeting in the morning chaired by Prime Minister Narendra Modi.

A Congress-led government was in power in the state, but following defections, when 21 out of 47 legislators had rebelled against the chief minister, the governor had advanced the session of the Assembly. The Congress had gone to court and obtained a stay on the proceedings.

The Bharatiya Janata Party (BJP) has 11 MLAs in a House of 60.

The Union Cabinet’s decision to impose Article 356 in the state comes even as the matter is being heard in the Supreme Court. A letter has been sent to the President's office conveying the Cabinet decision to impose President's Rule in the border state. The Assembly has been kept in suspended animation.

“The government knows it does not have majority in the Rajya Sabha. It did this so that it can alter the complexion of the Assembly before the matter comes up in Parliament,” said Congress leader Kapil Sibal.

A five-member Constitution bench is hearing the legal validity of the governor’s decision.

The governor’s message dated December 9 further instructed that the procedures related to the removal of the Speaker “shall be completed at the first sitting of the session itself” and that “until the session is prorogued, no presiding officer shall alter the party composition in the House”.

The Congress had argued there is no provision either under the Constitution or the Rules of Procedure and Conduct of Business, which empowers the governor to advance the session of the Assembly without consulting the chief minister and council of ministers.

It is the CM and the council of ministers that recommend convening of the Assembly.
