The Congress plans to move the Supreme Court to challenge Rajya Sabha Chairman M Venkaiah Naidu’s rejection of an impeachment notice filed by opposition parties against Chief Justice of India Dipak Misra.

Senior Congress leader Kapil Sibal reportedly said that Naidu’s order jeopardised the country’s legal system and said the government was not keen to see a probe into the case.

“To say the least, the order is unprecedented, illegal, ill-advised and hasty,” Sibal said, adding that it had been passed without a full-fledged enquiry. “We will certainly move a petition in the Supreme Court to challenge this order.”

Describing Naidu’s move as “unprecedented”, the Congress leader reportedly stressed that never before in India’s history had a motion moved by MPs been dismissed at the preliminary stage.

“It is illegal because the chairman has passed an order which is required to be passed after a full-fledged inquiry,” Sibal reportedly said, adding that the Rajya Sabha chairman had to only ascertain whether the motion was in order.

He wondered what the hurry was to reject the motion which had the valid signatures of 64 MPs, reported PTI.

“It is our privilege to move the motion. You cannot boot the privilege in this manner,” Sibal was quoted as saying.

The order had shattered the confidence of the people and jeopardised the legal system, he added.
