Usage in regard to contracts Generally speaking, in the civil law system there are four principal methods of nullifying a contract or of bringing it to an end: (1) annulation, anulación, where there is a fundamental defect in its formation; (11) rescision, rescisión, where the contract causes lesion to one of the parties; (iii) résolution, resolución, where one of the parties fails to perform or cannot perform his obligations; (iv) résiliation, denuncia, where the parties agree to end a contract part of which has been performed. - 1168 - In the first three cases, the contract is made void ab initio, i.e. generally speaking it has no legal effect whatsoever; in the last case its legal effects cease when it is brought to an end. In the Civil law system, situations (i), (ii) and (iii) are all covered under English law by the term avoidance: (i) and (ii) correspond to rescission 1/ used in its strict sense, ¿/ in which the contract is rendered void ab initio, and (iii) to rescission used in a broader sense deprecated by some writers. Situation (iii) does not render the contract void ab initio and alternative descriptions of it are avoidance for breach, discharge by breach or simply termination, commonly called cancellatioia. especially in the
