“(1) there are conflicting authorities as to whether the ‘principe de non-cumul’ should be extended to amount to a ‘principe de non option’; (2) there are local authorities which have endorsed the French authorities to the effect that a party to a contract may sue another party to the contract in tort if the breach of contract amounts to a faute lourde, the idea behind this rule being to allow a party to a contract to benefit from certain advantages of an action in tort when he is able to prove that the breach amounted to a faute lourde on the part of the other party concerned; (3) having regard to our rules and tradition in relation to pleadings and the spirit of fairness and justice, a plaintiff who wishes to plead faute lourde rather than breach of contract should be allowed to proceed in accordance with that option; …”
“A contractor may not treat as a delict the breach of any obligation contained in the contract; tortious liability can exist only where contractual liability does not; the rule is not concurrence but incompatibility. The Court of Cassation has said on many occasions ‘que les articles 1382 et suivants ne sont pas applicable lorsqu’il s’agit d’une faute comprise dans l’exécution d’une obligation résultant d’un contrat.’ Legal writers are almost unanimous that this is the positive law and a clear majority approve of it, though some would prefer the distinctions in the regulation of the two regimes [contract and tort] to be diminished or abolished. It has been suggested that a contractor may be sued in delict if his breach was deliberate or criminal or an abuse of rights; Savatier has contended that concurrence is admissible unless the only harm complained of is the failure to receive the promised performance. But the overwhelming view is that concurrence is quite excluded.”
“Principe dit du non-cumul - Ce principe, dont la dénomination n’est pas suffisamment claire, interdit à la victime, non seulement de cumuler ou de combiner les deux régimes de responsabilité, mais encore de choisir l’un ou l’autre. Si les conditions de mise en jeu de la responsabilité contractuelle sont réunies, ses règles doivent s’appliquer, sinon il convient de se référer à celles de la responsabilité delictuelle.”
“Jurisprudence. La jurisprudence, après avoir hésité, s’est prononcée, en principe, contre le ‘cumul’ des responsabilités. Elle a décidé que les dispositions des articles 1382 et suivants sont sans application lorsqu’il s’agit d’une faute commise dans l’exécution d’une obligation résultant d’un contrat.”
“On a parfois proposé d’admettre le cumul des responsabilités en cas de faute intentionnelle d’un contractant, le dol permettant alors l’application des règles délictuelles … Des partisans du ‘cumul’ ont prétendu que les règles ordinaires de la responsabilité contractuelle ne jouent pas en cas de dol, celui-cí faisant naître une responsabilité délictuelle. Le raisonnement est inexact: en cas d’inexécution dolosive, les règles de la responsabilité sont certes différentes, mais cela ne tient pas à ce que la responsabilité cesse d’être contractuelle. Comment le cesserait-elle, puisqu’il y a toujours inexécution du contrat?”
“I find that [the] plaintiff is entitled to go beyond the contract and to ground his claim in tort, but I accept that the tort arises out of the non-performance of the normal obligations contained in the contract.”
“Our system of civil liability which is set down in our civil code which is of French origin does not permit a ‘Cumul de la responsabilité contractuelle et de la responsabilité délictuelle’. In fact the problem is one of ‘option’ and not ‘cumul’ since according to certain authors and a number of decided cases a breach of contract would give an aggrieved party an option between an action in tort or in contract at his choice depending on which of the two is deemed to be the more favourable. The problem of ‘option’ has however been widely abandoned now. Liability is either based on contract or on tort and the basis of liability is an exclusive one. There is now a well established doctrine and jurisprudence whereby parties who are linked by contract must ground any claim they may have on the basis of contractual liability and not in tort - Vide Starck, Droit Civil Obligations, 1972, par 2058; P Le Tourneau, la responsabilité civile, 3e éd, 1982, Dalloz no 164 et s; Civ 1re,16 nov 1965 , D 1966.61.”
“There is no doubt that there exists between the parties a contractual relationship of client and banker and more specially with regard to the operation of the Global Access Card which is the subject matter of the present litigation. Any matter whereby one party would be in breach of his obligation would therefore have to be governed by the contractual terms existing between them. Pursuant to the ‘non-cumul’ rule, liability can be based either in tort only or in contract only. The two types of liability cannot be mixed up.”
“The concept of the ‘faute lourde’ in the execution of obligations under a contract has been developed by the French courts to temper the strict application of the principle of ‘non-cumul des responsabilités’ which may in instances lead to unjust results … The French courts have developed a notion of ‘faute lourde’ and have assimilated it to the notion of ‘dol’ under article 1150 which would give rise to damages not foreseen or foreseeable under a contract and as a result, rendering ‘clauses de non-responsabilité’ and ‘clauses limitative de responsabilité’ which may be found in a contract, null and void. The action remains one on the contract and not in tort. The question whether an action based on the non-execution of a contractual obligation albeit on the commission of a ‘faute lourde’ is an action under article 1382 of the Code Civil has not been without controversy as attested to by the numerous views of the French doctrine. However the general view is that the action is still one of breach of contractual obligation ...”
