Quasi-Delict Legal Definition:
Civil law: a delict (wrong) caused by negligence.
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."
