Summarise judgment in Payzu v Saunders [1919]

It was held that the plaintiff had permitted himself to sustain a large measure of the loss which, as prudent and reasonable people, they ought to have avoided. He had the cash available to meet the defendant’s demands and could have mitigated by purchasing off the defendant at the contract price as the defendant offered, instead of going into the market to purchase at a higher price. He was, therefore, not entitled to damages.
