Lumley v. Wagner, (1852) 1 De G.M. & G. 604; 42 Eng. Rep. 687 (Ch.)
Lumley v. Wagner is a foundational contracts-and-remedies decision from the English Court of Chancery that articulates a durable principle: while courts of equity will not specifically enforce affirmative personal service obligations, they may enforce a negative covenant that restrains the promisor from performing those services for others during the contract term.
May a court of equity enjoin a performer from appearing for others in breach of an exclusivity covenant in a personal services contract when the court cannot specifically compel the performer to render those services for the promisee?
Courts of equity will not grant specific performance of affirmative personal service obligations due to concerns about involuntary servitude, impracticability of supervision, and policy. However, where a personal services contract includes an express (or necessarily implied) negative covenant not to perform those services for others, equity may grant a negative injunction restraining the promisor from breaching that covenant if the services are unique, damages at law are inadequate, and the negative undertaking is clear, reasonable, and supported by consideration.
Yes. The Court of Chancery granted a negative injunction restraining Wagner from performing at any theatre other than Lumley's during the contract term, while declining to compel her to perform affirmatively for Lumley.
Lumley v. Wagner remains the cornerstone case on enforcing exclusivity in personal services contracts. It introduced the canonical blueprint for protecting unique services through negative injunctions and shaped the jurisprudence of equitable remedies across common-law jurisdictions. The case is frequently paired with Lumley v. Gye (recognizing a tort for inducing breach) to illustrate how both private ordering (contract) and deterrence of third-party interference reinforce exclusive service arrangements. For students, the case clarifies adequacy of remedies analysis, the limits of specific performance, the role of negative covenants, and the continuing relevance of tailored equitable relief in modern entertainment, media, and sports contracts.
