The party has said that it would move court against the ordinance as it contends that the state Assembly had duly passed the Appropriation Bill on March 18 and the Speaker had declared it so.
"Can there be two budgets? One passed by the state Assembly and the other promulgated through an ordinance by the central government?"
"How can the central govt be the arbiter of proceedings in a Vidhan Sabha? The Centre's move is unconstitutional," party spokesman Manish Tewari said.
"It is the Modi government's sinister conspiracy to obstruct and annul implementation of public welfare schemes and programmes, funds for which were allotted in the Budget," he alleged.
Terming the move as "legislative dishonesty" of the BJP government to deny genuine developmental aspirations of the people of Uttarakhand, he claimed that this was done first by proroguing Parliament and then "following the ordinance route to perpetuate illegalities".
Congress has accused the Centre of having "murdered democracy" by imposing President's rule in the state.
