Issuing a press statement on Sunday, NC President Deuba blamed that particular event had violated the constitution.
Chief Minister of Lumbini Province Shankar Pokhrel tendered his resignation from his post, ahead of the day when the voting on the no-confidence motion was scheduled to be held.
Deuba, also former Prime Minister, claimed that the resignation had been tendered after learning that the CPN-UML lost a clear majority and the move came as an act to ward off the no-confidence motion in the Province Assembly.
He asserted that the reappointment of Pokhrel as the Chief Minister following the resignation was illogical politically, constitutionally and morally.
Furthermore, Deuba argued that tendering resignation during the time when the process for a no-confidence motion was moving ahead but ending the session of Province Assembly was also against the spirit and values of constitutional and parliamentary, said Deuba in the statement.
