## Facts

- Dr. O’Flanagan, intending to sell his medical practice to Dr. With, represented in January 1934 that the practice made £2,000 per year.
- This statement was true when made.
- Subsequently, Dr. O’Flanagan became ill and the practice's income dropped substantially.
- By May 1934, when the sale contract was signed, the practice's earnings were significantly lower.
- Dr. O’Flanagan did not disclose the change in income to Dr. With before the contract was concluded.

## Issues

1. Whether a person who has made a statement of fact during contractual negotiations is under a duty to inform the other party if circumstances change, rendering the statement incorrect before the contract is signed.
2. Whether silence, in the context of a change to the truth of an initial representation, can constitute a misrepresentation actionable under contract law.

## Decision

- The Court of Appeal held that Dr. O’Flanagan was obliged to disclose the change in the practice's income.
- The court found that the original statement, though true at the time made, became false by the time of contract and continued to operate as a misrepresentation if not corrected.
- Lord Wright MR explained that failure to update the other party about a material change was equivalent to making a false claim.
- The decision confirmed that fairness in contract negotiations requires disclosure when facts behind a previous representation have materially changed.

## Legal Principles

- A party who makes a factual statement during contract negotiations has a continuing duty to correct that statement if it becomes untrue before contract formation.
- Silence is not ordinarily a misrepresentation, but when a previous true statement becomes false, remaining silent can amount to an actionable misrepresentation.
- The principle applies broadly to factual representations and to stated intentions or plans if those intentions change prior to contracting.
- Later cases, such as Spice Girls Ltd v Aprilia World Service BV [2002] EWCA Civ 15, have used similar reasoning, treating unspoken or continuing representations as actionable if rendered false by subsequent events.

## Conclusion

With v O’Flanagan [1936] Ch 575 established that parties must update or correct statements that become untrue during contractual negotiations, making it a foundational authority for the duty of honest disclosure and fair dealing in contract law.
