Quasi-tort is a legal term that is sometimes used to describe unusual tort actions, on the basis of a legal doctrine that some legal duty exists which cannot be classified strictly as negligence in a personal duty resulting in a tort nor as a contractual duty resulting in a breach of contract, but rather some other kind of duty recognizable by the law. It has been used, for example, to describe a tort for strict liability arising out of product liability, although this is typically simply called a 'tort'.
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 conflict of laws, the choice of law rules for tort are intended to select the lex causae by which to determine the nature and scope of the judicial remedy to claim damages for loss or damage suffered.
History.
The first attempts to establish a coherent choice of law rule for tort cases involving a foreign law element varied between favouring the lex fori (for example the law of the court) and the lex loci delicti commissi (for example the law of the place where the tort was committed). The public policy of territorial sovereignty was always the principal consideration. Hence, the forum courts claimed their right to apply their laws to determine whether any lawsuit initiated in their jurisdiction allowed a remedy. Equally, it is the commission of a tort that vests a right of action in a claimant and therefore, it should always be for the law of the place where that right was created to determine the extent of any remedy flowing from it. In the end, a compromise emerged where the lex loci delicti was the first point of reference but courts retained a discretion to substitute the lex fori if the foreign law was deemed unfair and other practical considerations pointed to the application of forum law.
In the U.S., see the New York decision in Babcock v Jackson, (1963) for a discussion of the issues. This led to a debate in which state interests, rather than strict territorial connections, were suggested as the basis of a new test. In 1971, the American Law Institute produced the Second Conflicts Restatements and section 6 provides that the applicable law should be the one with the "most significant relationship" to the tort. In other common law states, a parallel movement occurred and resulted in the adoption of a proper law test. In substance, both forms are similar in their approach.
