Cook v Deeks [1916] UKPC 10 is a Canadian company law case, relevant also to UK company law, concerning the illegitimate diversion of a corporate opportunity. It was decided by the Judicial Committee of the Privy Council, at that time the court of last resort within the British Empire, on appeal from the Appellate Division of the Supreme Court of Ontario, Canada.

In UK company law, the case would now be seen as falling within the Companies Act 2006 section 175, with a failure to have ratification of breach by independent shareholders under section 239.

GM Deeks, GS Deeks, and Hinds took a contract with the Canadian Pacific Railway Company (for building a line at the Guelph Junction and Hamilton branch) in their own names. They then passed a shareholder resolution declaring that the company had no interest in the contract. Cook claimed that the contract did belong to the Toronto Construction Co and the shareholder resolution ratifying their actions should not be valid because the three directors used their votes to carry it.
Decision
The Privy Council advised that the three directors had breached their duty of loyalty to the company, that the shareholder ratification was a fraud on Mr Cook as a minority shareholder, and invalid. Giving the advice, The Lord Chancellor, Lord Buckmaster held the result was that the profits made on the contractual opportunity were to be held on trust for the Toronto Construction Co.
Lord Buckmaster said that the three had,
