In Edwards v Chesterfield Royal Hospital N.H.S. Foundation Trust the majority of a seven-justice Supreme Court held that a common law claim for breach of express contractual disciplinary procedures was pre-empted by the statutory right to claim for unfair dismissal. Further, they held that one express term (the notice clause) should be prioritised over another (the contractual disciplinary procedure). In this article we argue that the application of the idea of statutory “trumping” of the common law misunderstands the complex evolution of the common law in this field and its interplay with statute. We also argue that the traditional pre-eminence given to notice clauses over all other express terms needs to be reconsidered.
