Roscorla v Thomas (1842)
Case Summary: This case establishes a crucial principle of contract law concerning past consideration.
Facts:
Holding (Decision): The court held that the defendant's promise was not binding.
Reasoning:
The core problem lies in the timing of the consideration. The plaintiff's consideration (paying £30) occurred before the defendant's promise that the horse was sound. This is known as past consideration. Past consideration is generally not good consideration to support a new contract.
The act of buying the horse was complete before the promise of soundness was made. Therefore, there was no "bargain" or exchange between the two parties regarding the soundness promise. The promise was a gratuitous undertaking (a promise made without any exchange of something of value), and thus, unenforceable.
Key Principle: For a contract to be valid, there must be a valid consideration that is given in exchange for a promise. This consideration must be present or future – given or promised in exchange for the promise in question. Past consideration, where the consideration pre-dates the promise, is insufficient to form a legally binding contract.

Case Summary: This case establishes a crucial principle of contract law concerning past consideration.
Facts:
- The plaintiff (Roscorla) bought a horse from the defendant (Thomas) for £30.
- After the sale was completed, the defendant promised the horse was "sound and free from vice."
- This promise was made after the plaintiff had already provided consideration (the £30) for the sale of the horse.
Holding (Decision): The court held that the defendant's promise was not binding.

Study Points & Practice Questions:
- Define "consideration" in contract law. (An act, forbearance, or promise made by one party in exchange for a promise by another)
- Explain the difference between past, present, and future consideration. Provide examples.
- Why is past consideration generally insufficient? (Because there is no bargain or exchange; it's a gratuitous promise)
- What would the outcome be if the defendant had promised the horse was sound before the sale was finalized? (This would be good consideration as the promise would be part of the initial bargain.)
- Find other cases which exemplify the rules of consideration. (e.g., Eastwood v Kenyon)
- Illustrate with examples how this case affects everyday transactions. (e.g., a promise made after the purchase of a car to cover repair costs; a promise made after services have been rendered.)
