UNION OF INDIA vs DEO NARAIN .

The Supreme Court upheld the decision of the Central Administrative Tribunal (CAT) regarding the promotion of Lower Division Clerks (LDCs) to Upper Division Clerks (UDCs). The Court found that the non-consideration of the applicants for promotion based on their placement in the combined seniority list was arbitrary and irrational, violating principles of fair administrative action. The Court affirmed the CAT's directive to the Department to consider the applicants' cases for promotion in accordance with their past service, thereby dismissing the appeal of the Union of India.
