The Civil Code (Section 6:145.) excludes the possibility of parallel delictual claims of compensation for damages arising from breach of contract (non-cumul). This essay deals with the concept of concurrence of law and the concept of cumulation of causes of action and the relationship between contractual remedies and other sanctions grounded on a non-contractual basis. It examines the French doctrine of non-cumul, the proposal of DCRF and certain methods among the European legal systems. This essay analyzes briefly the two situations where the contractual and delictual bases could compete with each other and the application of the above mentioned provision may generate problems.
