Supreme Court of the United Kingdom
Supreme Court of the United KingdomMay 5, 2026

Why It Matters

The ruling will set a precedent on whether collective agreements can be legally corrected, impacting wage obligations and dispute resolution for public transport employers and unions across the UK.

Key Takeaways

  • Court of Appeal rejected rectification of Nexus‑union collective agreement.
  • Appellant claims rectification applies despite statutory unenforceability in practice.
  • Jurisdiction of employment tribunals on contract rectification contested.
  • Abuse‑of‑process argument pivotal to limiting further claims in litigation.
  • Decision could reshape pay obligations for Nexus employees.

Summary

The appeal concerns Nexus, the Tyne and Wear Passenger Transport Executive, seeking to rectify a letter of agreement that records a collective bargaining deal with the RMT and Unite unions. The Court of Appeal held that, because collective agreements are statutorily presumed unenforceable, the equitable remedy of rectification could not be applied, effectively dismissing the appellant’s claim. The appellant argues that rectification is a flexible equitable tool that can correct the written record of a transaction even when the underlying agreement is unenforceable, especially where the document influences contractual obligations such as employee pay. He also raises three ancillary grounds: the employment tribunal’s jurisdiction to consider rectification, the potential abuse‑of‑process in limiting further claims, and issues of privity and estoppel. Key excerpts highlight the contention that the appellate judges erred in restricting rectification and that the abuse‑of‑process analysis should be left to a higher court or tribunal. The appellant stresses that the collective agreement, though not directly enforceable, shapes the terms of employment contracts and therefore warrants judicial correction. If the Supreme Court overturns the appellate ruling, it could open the door for unions to seek rectification of collective agreements, altering how pay and conditions are enforced and potentially exposing employers like Nexus to renewed liability for past and future wage disputes.
