The party's chief spokesman Randeep Surjewala told reporters that the move was "unfortunate" and "smacks of growing authoritarian tendencies".
His remarks came in the wake of reports that President Pranab Mukherjee on Sunday signed an ordinance or executive order for the fourth time to amend a law that the government has been unable to pass in Parliament, but is reportedly upset as it was sent to him this time without being routed through the Union Cabinet.
This is the first time since Independence that an ordinance has been sent to the President without the Cabinet first clearing it
Lok Sabha had passed a bill to amend the act earlier this year, but opposition parties want it reviewed and have stalled it in Rajya Sabha, where the government is in a minority, forcing it to keep it alive by issuing ordinance after ordinance.
