Personal Jurisdiction

A court's power over a particular defendant, measured by contacts with the forum, fair play, and proper notice. Without it, a judgment is void and unenforceable in other states.

Related: Minimum Contacts, In Rem Jurisdiction, Venue
Minimum Contacts

The purposeful connection between a defendant and the forum state that makes exercising jurisdiction fair. Isolated contacts generally do not suffice; systematic and continuous activity supports general jurisdiction.

Related: Personal Jurisdiction, Specific Jurisdiction, General Jurisdiction
Specific Jurisdiction

Jurisdiction over a claim that arises out of or relates to the defendant's purposeful contacts with the forum. Fairness factors such as burden and state interest are then weighed.

Related: Minimum Contacts, Personal Jurisdiction, Long-Arm Statute
General Jurisdiction

Jurisdiction over any claim against a defendant whose affiliations with the forum are so continuous and systematic as to render it essentially at home there, typically its place of incorporation or principal place of business.

Related: Minimum Contacts, Specific Jurisdiction, Domicile
Venue

The proper geographic location within a court system for filing suit, usually where a defendant resides or where events giving rise to the claim occurred. It is distinct from jurisdiction and can be waived.

Related: Personal Jurisdiction, Forum Non Conveniens, Removal
Forum Non Conveniens

A discretionary dismissal doctrine letting a court decline a case when another forum is substantially more convenient and the plaintiff has an adequate alternative remedy. Usually requires a strong showing of inconvenience.

Related: Venue, Personal Jurisdiction, Erie Doctrine
Erie Doctrine

The rule that a federal court sitting in diversity applies state substantive law but federal procedural rules. Courts decide whether a state rule is substantive by outcome determination, forum shopping, and inequitable administration concerns.

Related: Diversity Jurisdiction, Federal Question Jurisdiction, Forum Non Conveniens
Diversity Jurisdiction

Federal subject-matter jurisdiction over civil actions between citizens of different states (or citizens and aliens) where the amount in controversy exceeds $75,000. Complete diversity must exist when the complaint is filed.

Related: Federal Question Jurisdiction, Erie Doctrine, Supplemental Jurisdiction
Federal Question Jurisdiction

Federal jurisdiction over claims arising under the Constitution, treaties, or laws of the United States, as shown on the face of a well-pleaded complaint. It does not require a minimum amount.

Related: Diversity Jurisdiction, Supplemental Jurisdiction, Removal
Supplemental Jurisdiction

Federal jurisdiction over additional claims that are part of the same case or controversy as a claim with original jurisdiction. In diversity cases, it cannot extend to claims by plaintiffs against nondiverse parties.

Related: Diversity Jurisdiction, Federal Question Jurisdiction, Removal
Removal

A defendant's procedure for transferring a case from state to federal court within 30 days of service, available only if the federal court would have had original jurisdiction. In-state defendants generally cannot remove.

Related: Diversity Jurisdiction, Federal Question Jurisdiction, Venue

Issue preclusion: a fact or issue actually litigated and necessarily decided in a prior case cannot be relitigated against a party who had a full and fair opportunity to contest it.

Related: Res Judicata, Summary Judgment, Directed Verdict

Related: Directed Verdict, Res Judicata, Judgment as a Matter of Law

Related: Consideration, Mirror Image Rule, Promissory Estoppel
Consideration

A bargained-for exchange of legal detriment or benefit that makes a promise enforceable. Past acts, moral obligations, and illusory promises generally do not qualify.

Related: Offer and Acceptance, Promissory Estoppel, Statute of Frauds

Enforcement of a promise without consideration when the promisor reasonably expected reliance, the promisee actually relied, and injustice can be avoided only by enforcement. Recovery is often limited to reliance damages.

Related: Consideration, Detrimental Reliance, Offer and Acceptance
Statute of Frauds

A clear statement or act before performance is due indicating a party will not perform. The nonbreaching party may treat it as breach immediately or wait for performance.

Related: Perfect Tender Rule, Impracticability, Material Breach

Excuse when an unforeseen event destroys the principal purpose of the contract, so performance has no value to the party seeking relief. Both parties must have assumed the purpose would continue.

Related: Impracticability, Anticipatory Repudiation, Material Breach
Material Breach

A failure to perform that is substantial enough to excuse the other party's remaining duties and permit damages. Minor breaches allow continued performance but still support damages.

Related: Anticipatory Repudiation, Perfect Tender Rule, Expectation Damages
