Quasi-Delict Legal Definition: Civil law: a delict (wrong) caused by negligence. Related Terms: Tort , Delict , Civil Law , Civil Liability , Obligations A quasi-delict is a negligent act or omission which causes harm or damage to the person or property of another, and thus exposes a person to civil liability in civil law jurisdictions, as if the act or omission was intentional (a delict). Quasi-delicts were not recognized by early Roman law. Gaius, for example, defined obligations as comprised only of delicts and contracts. Quasi-delicts only received official recognition in the publication of Justinian's Institutes in about 533 and thereafter were part and parcel of Roman law and, later, civil law. Robert-Joseph Pothier defined a delict as intentional harm. But a quasi-delict, wrote Pothier is: " ... where a person, not with malice but by inexcusable carelessness, causes harm to another." In his 1967 Dictionaire de Droit, Barraine defines a quasi-delict as: "Any unintentional and unlawful act or omission which causes damages." French: quasi-délit.
