Williams v. Roffey Bros [1990] 1 All ER 512
Study notes for Williams v. Roffey Bros: professor notes, cold call prep, exam angles, and memory aids.
A promise to perform an existing duty may be enforceable if it ensures a practical benefit for the promisor.
The case of Williams v. Roffey Bros is significant in contract law as it explores the doctrine of consideration, particularly in the context of existing contractual duties. The court, in this case, identified that a promise can be enforceable even if it alters the terms of an existing obligation, provided that the promisor gains a practical benefit. Professors often emphasize how this decision marks a shift in the traditional view that consideration must consist of a new benefit or detriment, providing insight into modern contractual arrangements. Additionally, it's crucial to consider how this case illustrates the balance between enforceability and public policy in contract law.
Practical Benefit = Enforceable Promise
| Case | Distinction |
|---|---|
| Stilk v. Myrick | Stilk ruled that existing duties cannot constitute consideration, whereas Williams v. Roffey Bros allowed for practicality to create enforceability. |
| Foakes v. Beer | Foakes established that part payment of a debt is not consideration, while Williams illustrates that additional performance of an existing duty can be valid consideration. |
| Re McArdle | Re McArdle requires consideration to be in exchange for a benefit at the time promised, whereas Williams v. Roffey Bros emphasizes practical benefits derived from promises made regarding existing duties. |
Allowing enforceability of promises that offer practical benefits aligns with modern commercial realities and promotes fairness in transactional relationships.
This rule may encourage coercion or pressure in renegotiations of contracts, as parties may feel compelled to agree to new terms for fear of losing a contract.
This case is often used in exams to illustrate contemporary applications of consideration and to examine how courts interpret practical benefits in contract disputes. Students should be prepared to analyze the implications of its holding in different contractual contexts.
