## Facts

- The Duke of Somerset sought judicial relief for the recovery of a silver cup alleged to have been wrongfully retained by Cookson after a series of transactions whose details are not material to the legal principle ultimately addressed.
- The cup was no ordinary chattel: it possessed considerable historical, aesthetic, and sentimental significance to the Duke’s family lineage. It was, therefore, classified by the court as “special property” rather than fungible personalty.
- The Duke maintained that an award of money would fail to compensate him adequately because the cup’s value lay predominantly in its provenance and familial association, qualities that could not be replicated through a monetary equivalent.
- Evidence placed before the court described the cup’s distinctive engravings, its age, and its links to prior holders within the Somerset family. Witnesses and documents established a chain of title and attested to its irreplaceable character.
- The defendant did not contest the cup’s distinctiveness but advanced the position that any loss could be compensated by damages, urging the court to refuse equitable relief and remit the claimant to an action at law.
- The proceeding was brought in the Court of Chancery, where equitable jurisdiction allowed the Chancellor to decree the surrender of property rather than merely assess damages.

## Issues

1. Whether a claimant who seeks the return of an item classified as special property is entitled to an order of specific performance (or, more precisely, specific delivery) instead of an award of damages.
2. What quality and quantity of proof are required to satisfy the court that the property is truly unique and that ordinary damages would be inadequate for complete justice.

## Decision

- Lord Chancellor Talbot held that the appropriate remedy was an order compelling the defendant to deliver the silver cup to the Duke of Somerset.
- The court reasoned that the basis of equity is to grant relief where the common law is deficient. Because damages could not replicate the sentimental and historical attributes of the cup, the legal remedy was plainly inadequate.
- The Chancellor indicated that jurisdiction to compel delivery of unique chattels already existed in earlier precedent but clarified the doctrinal line between cases involving goods readily obtainable on the market and those involving singular items.
- The evidentiary burden was expressed as “clear and convincing,” requiring the claimant to establish with precision both the item’s uniqueness and the inadequacy of damages. The Duke met that burden through documentary proof of provenance and testimonial corroboration.
- Consequentially, a decree issued directing Cookson to return the cup forthwith, failing which the court would entertain coercive measures typical of Chancery practice, such as attachment for contempt.

## Legal Principles

- Distinction between general property and special property: General property refers to goods that can be replaced by purchase on the open market. Special property refers to items with individual characteristics—historical, artistic, sentimental, or symbolic—that render them not fungible.
- Adequacy of damages: Equity acts only where remedies at common law are insufficient. Because the loss of a unique object cannot be made good by a financial substitute, equitable intervention is justified.
- Evidentiary standard: The claimant must provide evidence that goes beyond mere assertion. Authenticating documents, expert testimony on historical value, or proof of family association are typical means of discharging that burden.
- Discretionary nature of equitable orders: Even when uniqueness is proven, equitable relief may still be refused if the claimant’s own conduct is tainted by laches, unclean hands, or undue delay. The Duke’s prompt resort to the court and absence of wrongful conduct satisfied the court’s conscience.
- Precedential effect: The case articulated an early and influential statement that specific performance (or delivery) is not confined to land contracts but extends to movable property when uniqueness demands it, thereby shaping later jurisprudence on art objects, heirlooms, and closely held shares.

## Conclusion

Somerset v Cookson firmly established that where personal property is shown to be unique—whether by its history, craftsmanship, or personal association—specific performance in the form of delivery is the appropriate remedy. The case articulated the dual requirements of demonstrating the item’s singular nature and the insufficiency of money damages, thereby setting a durable standard for equitable intervention in property disputes that continues to inform modern doctrine.
