Personal jurisdiction is a court's jurisdiction over the parties to a lawsuit, as opposed to subject-matter jurisdiction, which is jurisdiction over the law and facts involved in the suit. If a court does not have personal jurisdiction over a party, its rulings or decrees cannot be enforced upon that party, except by comity; i.e., to the extent that the sovereign which has jurisdiction over the party allows the court to enforce them upon that party. A court that has personal jurisdiction has both the authority to rule on the law and facts of a suit and the power to enforce its decision upon a party to the suit. In some cases, territorial jurisdiction may also constrain a court's reach, such as preventing hearing of a case concerning events occurring on foreign territory between two citizens of the home jurisdiction.
The forms of action were the different procedures by which a legal claim could be made during much of the history of the English common law. Depending on the court, a plaintiff would purchase a writ in Chancery which would set in motion a series of events eventually leading to a trial in one of the medieval common law courts. Each writ entailed a different set of procedures and remedies which together amounted to the "form of action".
In laws of equity, unjust enrichment occurs when one person is enriched at the expense of another in circumstances that the law sees as unjust. Where an individual is unjustly enriched, the law imposes an obligation upon the recipient to make restitution, subject to defences such as change of position. Liability for an unjust enrichment arises irrespective of wrongdoing on the part of the recipient. The concept of unjust enrichment can be traced to Roman law and the maxim that "no one should be benefited at another's expense": nemo locupletari potest aliena iactura or nemo locupletari debet cum aliena iactura.
In personam is a Latin phrase meaning "against a particular person". In a lawsuit in which the case is against a specific individual, that person must be served with a summons and complaint (E&W known as Particulars of Claim to give the court jurisdiction to try the case, and the judgment applies to that person and is called an "in personam judgment".
In rem jurisdiction is a legal term describing the power a court may exercise over property or a "status" against a person over whom the court does not have in personam jurisdiction. Jurisdiction in rem assumes the property or status is the primary object of the action, rather than personal liabilities not necessarily associated with the property.
Forum non conveniens (FNC) is a mostly common law legal doctrine whereby a court "acknowledges that another forum or court is more appropriate and sends the case to such a forum. A change of venue, where another venue is more appropriate to adjudicate a matter, such as the jurisdiction within which an accident occurred and where all the witnesses reside."
In a court of law, a party's claim is a counterclaim if one party asserts claims in response to the claims of another. In other words, if a plaintiff initiates a lawsuit and a defendant responds to the lawsuit with claims of his or her own against the plaintiff, the defendant’s claims are “counterclaims.”
Shaffer v. Heitner, 433 U.S. 186 (1977), is a United States corporate law case in which the Supreme Court of the United States established that a defendant's ownership of stock in a corporation incorporated within a state, without more, is insufficient to allow that state courts to exercise jurisdiction over the defendant. The case set forth a framework for evaluating when a defendant will be deemed to have minimum contacts with the forum state sufficient for the exercise of jurisdiction to be consistent with due process under the Fourteenth Amendment.
International Shoe Co. v. Washington, 326 U.S. 310 (1945), was a landmark decision of the Supreme Court of the United States in which the Court held that a party, particularly a corporation, may be subject to the jurisdiction of a state court if it has "minimum contacts" with that state. The ruling has important consequences for corporations involved in interstate commerce, their payments to state unemployment compensation funds, limits on the power of states imposed by the Due Process Clause of the Fourteenth Amendment, the sufficiency of service of process, and, especially, personal jurisdiction.
Minimum contacts is a term used in the United States law of civil procedure to determine when it is appropriate for a court in one state to assert personal jurisdiction over a defendant from another state. The United States Supreme Court has decided a number of cases that have established and refined the principle that it is unfair for a court to assert jurisdiction over a party unless that party's contacts with the state in which that court sits are such that the party "could reasonably expect to be haled into court" in that state. This jurisdiction must "not offend traditional notions of fair play and substantial justice". A non-resident defendant may have minimum contacts with the forum state if they 1) have direct contact with the state; 2) have a contract with a resident of the state; 3) have placed their product into the stream of commerce such that it reaches the forum state; 4) seek to serve residents of the forum state; 5) have satisfied the Calder effects test; or 6) have a non-passive website viewed within the forum state.
A quasi in rem legal action is a legal action based on property rights of a person absent from the jurisdiction. In the American legal system the state can assert power over an individual simply based on the fact that this individual has property in the state. Quasi in rem jurisdiction does not have much function in the United States any longer. However, in very specific cases, quasi in rem jurisdiction can still be effective.
Pennoyer v. Neff 95 U.S. 714 (1878) was a decision by the Supreme Court of the United States in which the Court held that a state court can only exert personal jurisdiction over a party domiciled out-of-state if that party is served with process while physically present within the state.
Calder v. Jones, 465 U.S. 783 (1984), was a case in which the United States Supreme Court held that a court within a state could assert personal jurisdiction over the author and editor of a national magazine which published an allegedly libelous article about a resident of that state, and where the magazine had wide circulation in that state.
A subpoena ad testificandum is a court summons to appear and give oral testimony for use at a hearing or trial. The use of a writ for purposes of compelling testimony originated in the ecclesiastical courts of the High Middle Ages, especially in England. The use of the subpoena writ was gradually adopted over time by other courts in England and the European continent.
Morguard Investments Ltd v De Savoye, [1990] 3 SCR 1077 is the leading decision of the Supreme Court of Canada on the enforcement of extraprovincial judgments. The Court held that the standard for enforcing a default judgment from a different province is not the same as if it were from another country; rather the Court adopts the test from Indyka v Indyka, [1969] 1 AC 33 (HL) and the Moran v Pyle National (Canada) Ltd, [1975] 1 SCR 393 where there must be a "real and substantial connection" between the petitioner and the country or territory exercising jurisdiction.
Colorado River Water Conservation District v. United States, 424 U.S. 800 (1976), was a case in which the Supreme Court of the United States created a new doctrine of abstention, to prevent duplicative litigation between state and federal courts.
In admiralty law, a maritime lien is a privileged claim upon sea-connected property, such as a ship, for services rendered to, or the injuries caused by that property. In common law, a lien is the right of the creditor to retain the properties of his debtor until the debt is paid.
Burnham v. Superior Court of California, 495 U.S. 604 (1990), was a United States Supreme Court case addressing whether a state court may, consistent with the Due Process Clause of the Fourteenth Amendment, exercise personal jurisdiction over a non-resident of the state who is served with process while temporarily visiting the state. All nine justices unanimously agreed that this basis for personal jurisdiction—known as "transient jurisdiction"—is constitutionally permissible. However, the Court failed to produce a majority opinion, as the members were sharply divided on the reasons for the decision, reflecting two fundamentally different approaches to how due-process issues are to be analyzed. Justice Scalia wrote the lead opinion, joined in whole or part by three other Justices. Justice Brennan wrote an opinion joined by three other Justices. Justices White and Stevens wrote separate opinions.
Tolling is a legal doctrine that allows for the pausing or delaying of the running of the period of time set forth by a statute of limitations, such that a lawsuit may potentially be filed even after the statute of limitations has run. Although grounds for tolling the statute of limitations vary by jurisdiction, common grounds include:
Rule B attachments are issued under Rule B of the Supplemental Rules for Certain Admiralty and Maritime Claims of the Federal Rules of Civil Procedure. Under that provision, the court is allowed to attach a defendant's property up to the value of the suit. Although these claims are filed during in personam actions, they are in rem in nature, as the Court is attaching property to the suit. This has been described as a "remedy quasi in rem."
