PALURU RAMKRISHNAIAH & ORS. ETC. vs UNION OF INDIA & ANR.

The Supreme Court held that executive instructions cannot override statutory rules, specifically referencing the Indian Ordnance Factories (Recruitment and Conditions of Service of Class III Personnel) Rules, 1956, particularly Rules 8 and 12. The Court found that the promotion from Supervisor Grade 'A' to Chargeman II was governed by these rules, and any automatic promotion contrary to the prescribed procedure would be invalid. The Court upheld the dismissal of the writ petition, affirming that the petitioners had no right to promotion without adherence to the established rules.
