As per case facts, the Petitioners challenged an Industrial Court's interim Order that stayed a circular from September 2025. The Order directed the Petitioners to continue granting additional wage increments ... to employees for specific diplomas, a practice ongoing since 1967. Petitioners argued this was a discretionary policy, while the Respondent Union claimed it was a service condition requiring a notice of change under Section 9-A of the Industrial Disputes Act. The question arose whether prospectively stopping such long-standing additional increments, which had become a customary concession, required a notice of change under Section 9-A. Finally, the Court upheld the interim Order. It ruled that the consistent practice had become a customary concession, and its unilateral withdrawal without a Section 9-A notice altered service conditions, justifying the interim relief to preserve the status quo.
