The correct answer is (c).
The Carry Forward Rule was held as ultra vires in the case of Pradeep Tandon Vs. State of up.P.
The Carry Forward Rule was a rule that allowed government employees to carry forward their unused leave to the next financial year. However, in the case of Pradeep Tandon, the Supreme Court held that this rule was ultra vires, as it violated the fundamental right to equality.
The Court held that the Carry Forward Rule was discriminatory, as it allowed only government employees to carry forward their unused leave, while private sector employees were not allowed to do so. The Court also held that the rule was arbitrary, as there was no reason why government employees should be allowed to carry forward their unused leave while private sector employees were not.
The Court’s decision in the case of Pradeep Tandon Vs. State of up.P. was a landmark decision, as it established the principle that government employees cannot enjoy any special privileges that are not available to private sector employees. The decision also had a significant impact on the Carry Forward Rule, as it led to the rule being abolished.
