Many civil-law systems contain provisions relating to unjustified enrichment: as in the BGB, the Civil Code of the Netherlands, the Swiss Code of Obligations, the Austrian Civil Code, and the Italian Civil Code after 1941; as well as the Portuguese and Greek civil codes; some Latin-American codes such as the federal Mexican one, and the Cuban one of 1987. In the Spanish and French law, the provision is a jurisprudential creation (except that in Navarre there is specific regional legislation dealing with the issue). In Roman law, the abstract formula of the condictio allowed a great variety of claims. I analyse a text of the Institutes of Gaius, 1,79 and D. 46,3,66, a complicated text of Pomponius ad Plautium that has given rise to diverse interpretations.
