A breach of contract occurs where a party to a contract fails to perform, precisely and exactly, his obligations under the contract. This can take various forms for example, the failure to supply goods or perform a service as agreed. Breach of contract may be either actual or anticipatory. Actual breach occurs where one party refuses to form his side of the bargain on the due date or performs incompletely. For example: Poussard v Spiers and Bettini v Gye. Anticipatory breach occurs where one party announces, in advance of the due date for performance, that he intends not to perform his side of the bargain. The innocent party may sue for damages immediately the breach is announced. Hochster v De La Tour is an example. Effects of breach A breach of contract, no matter what form it may take, always entitles the innocent party to maintain an action for damages, but the rule established by a long line of authorities is that the right of a party to treat a contract as discharged arises only in three situations.
