Procedural Posture

Employment and Labour Relations Constitutional Petition With Preliminary Objection / Ruling on Preliminary Objection

  1. 1 Whether the petition is res judicata
  2. 2 Whether the court is functus officio
  3. 3 Whether the petition raises a new cause of action on post-judgment fair representation

Ratio Decidendi

The court held that the petition is not res judicata because it raises a different question from the underlying ELRC Cause No. 41 of 2006: alleged breach of the union’s duty of fair representation in the post-judgment execution phase. That issue was not directly and substantially determined in the former proceedings. The court also held that it was not functus officio because it was being asked to determine a distinct post-judgment labour-rights dispute, not to reopen or vary the earlier judgment. The preliminary objection therefore failed.

Court Disposition

Preliminary objection dismissed with costs to the petitioners

Orders

  • The Notice of Preliminary Objection dated 1st December 2025 is dismissed.
  • Costs of the preliminary objection are awarded to the petitioners.
