 Although it is not to be found in most legal dictionaries, it has been used by some scholars such as Sri Lankan Lakshman Marasinghe.Lakshman proposes that the doctrine provides legal relief that falls outside tort or contract, but with some of the characteristics of tort or contract, as can be found in restitution (including unjust enrichment), equity (including unconscionable conduct), beneficiaries under a trust of the benefit of a promise, people protected by the valid assignment of promise, fiduciary duty, and contracts of insurance.In "Tort Theory", Lakshman Marasinghe posits that "quasi-delict", a doctrine in civil law jurisdictions, exists as well in common law.
