Riverlate Properties Ltd v Paul (1974) CA
Case Summary: This case concerns a unilateral mistake in a lease agreement. Riverlate Properties (plaintiff) leased a shop and maisonette to Paul (defendant) for £6,250. The 99-year lease, drafted by Riverlate, incorrectly placed the burden of all structural repairs solely on the landlord (Riverlate). Riverlate later claimed this was a mistake and sought to rescind the lease or have it rectified to share repair costs equally.
Key Issue: Can a party rescind a contract due to their own unilateral mistake (a mistake made by only one party) when the other party was unaware of the mistake and acted without sharp practice (unfair or deceptive conduct)?
Court's Decision (Held): The Court of Appeal, through Russell LJ, held that rescission was not possible. Because the defendant neither knew nor should have known about Riverlate's mistake, and engaged in no sharp practice, the mistake was purely unilateral. Therefore, Riverlate was not entitled to rescind the lease, even if offering the defendant the option to rectify the mistake.

Key Legal Principles:
- Unilateral Mistake: A mistake made by only one party to a contract. This is distinct from a mutual mistake (both parties mistaken) or a common mistake (both parties make the same mistake).
- Rescission: The unwinding of a contract, returning the parties to their pre-contractual positions. This is an equitable remedy (granted at the court's discretion).
- Rectification: Correcting a written contract to reflect the parties' actual agreement. This is also an equitable remedy.
- Sharp Practice: Unfair or deceptive conduct, implying dishonesty or manipulation. The absence of sharp practice was crucial to the court's decision.
- Burden of Proof: The plaintiff (Riverlate) had the burden of proving the defendant knew of the mistake or acted with sharp practice. They failed to do so.
Study Questions:
- What is the difference between unilateral, mutual, and common mistake?
- Under what circumstances might a court grant rescission for a unilateral mistake?
- What is the significance of the absence of "sharp practice" in this case?
- Why did the burden of proof rest on Riverlate Properties?
- What are the implications of this case for contract drafting and due diligence? (Hint: Consider the importance of clear and accurate contract language and thorough legal review)
