NAGESH SINGH vs B.D. VIRDI .

The Supreme Court held that the promotions of SC/ST candidates under Rule 13 of the IES Rules, 1961, without considering the claims of general category applicants, were legally unsustainable and violated Articles 14 and 16 of the Constitution. The retrospective amendment to Rule 13 was deemed unreasonable and arbitrary, leading to the Court striking it down. The Court directed a review of the promotions while ensuring that financial benefits already granted to the promoted candidates are protected.
