Forum shopping is a colloquial term for the practice of litigants having their legal case heard in the court thought most likely to provide a favorable judgment. Some jurisdictions have, for example, become known as "plaintiff-friendly" and so have attracted litigation even when there is little or no connection between the legal issues and the jurisdiction in which they are to be litigated.
Examples include the attraction of foreign litigants to the United States due to its expansive acceptance of personal jurisdiction and favorable litigation climate, and the United Kingdom for its stricter defamation laws and generous divorce settlements.
The term has become adopted in a wider context for the activity of repeatedly seeking a venue or willing listener for a concern, complaint or action, until one is found.
When a case is filed before a court, the court decides whether it has personal and subject matter jurisdiction, and if so, whether it is the most appropriate forum or venue. Under the doctrine of forum non conveniens, Latin for "inappropriate forum", a judge has a discretion to transfer a case if the court selected is not the most convenient one. If the courts in two states would accept civil jurisdiction, the plaintiff must be able to show that justice requires the trial to take place in the forum suggested by the plaintiff.
The plaintiff might have selected one forum on the following grounds:
The forum is not convenient to the defendant or his witnesses. There may be problems of expense of travel, health, or visa or entry permit.
The court, the judge, or the law is most likely to favour the plaintiff's case.
The defendant may take the following actions to seek a change of venue:
The defendant may petition the forum court that it should reject the jurisdiction and petition to transfer the case to an allegedly more convenient forum; or
If a case has been filed in another jurisdiction, the defendant may seek injunctive relief against the plaintiff in a second state, requiring that the plaintiff discontinue the action in the first forum and instead submit the case for hearing in this allegedly more convenient forum.
