Constitutional law For example, if two people think a law is
unconstitutional, one might sue another in order to put the lawsuit before a
court which can rule on its constitutionality. Because courts generally reserve jurisdiction for situations in which there is an actual
case or controversy – i.e., a real dispute between the parties – where such a suit is suspected, the court may refuse to exercise
jurisdiction. For example, the
European Court of Justice does not hear preliminary references arising out of hypothetical disputes. Originally stated in
Chicago & Grand Trunk Railway Company v. Wellman (1892), the collusive lawsuit rule is one the seven rules of the
constitutional avoidance doctrine established in
Ashwander v. Tennessee Valley Authority (1936) that requires that the
Supreme Court of the United States to "not [rule] upon the constitutionality of legislation in a friendly, nonadversary, proceeding, declining because to decide such questions 'is legitimate only in the last resort, and as a necessity in the determination of real, earnest and vital controversy between individuals. It never was the thought that, by means of a friendly suit, a party beaten in the legislature could transfer to the courts an inquiry as to the constitutionality of the legislative act.
Tort fraud Another form of collusive lawsuit involves
fraud, where two persons agree to fake an
accident, so that the "victim" can sue the other person in order to collect from the other person's
insurance. This is a
crime, and insurance companies investigate claims to determine that no collusion is involved. Because of the fear of collusive suits, many jurisdictions have, at various times, prohibited spouses from suing one another or prohibited children from suing their parents. Also, many jurisdictions have had
guest statutes which make it difficult for a
passenger in a non-commercial vehicle to sue the driver if the passenger is injured due to the driver's
negligence.
At-fault divorce Another example is in
divorce, in those
jurisdictions where
fault remains as a condition before commencement of an action for breach of the marriage contract.
Marketing Sham friendly lawsuits can help further false advertising claims. In 2015, pharmaceutical corporation
Gilead Sciences was sued by an organization it funded, the
AIDS Healthcare Foundation, on the basis of statements of
Treatment Action Group, another organization Gilead funded, asserting Gilead's older drug
tenofovir disoproxil was "less safe" than its newer counterpart
tenofovir alafenamide. The old drug was going off-patent and by 2023, generic versions cost $400 vs. $2,160/month for the new branded version. The active ingredient in both drugs is exactly the same and both versions have virtually identical safety profile, but the friendly lawsuit lead to widespread market perception the old drug was not safe thus creating demand for the new expensive version. The lawsuit also spurred numerous recruitment advertisements from class action lawyers looking for tenofovir disoproxil victims - free false advertising against Gilead's generic competitor. ==See also==
