Geys v Société Générale is an important case of the Supreme Court which rules on the question of whether a unilateral step by one party – say, a summary dismissal by an employer - can end a contract of employment without the other party accepting that repudiation, or whether the contract does not end until the employee does or says something to indicate that he accepts that the contract is at an end. The Supreme Court, by a majority, opted for the latter.
