International lawInternational law (also known as public international law and the law of nations) is the set of rules, norms, and standards generally recognised as binding between states. It establishes normative guidelines and a common conceptual framework for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in that it is primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states.
Choice of lawChoice of law is a procedural stage in the litigation of a case involving the conflict of laws when it is necessary to reconcile the differences between the laws of different legal jurisdictions, such as sovereign states, federated states (as in the US), or provinces. The outcome of this process is potentially to require the courts of one jurisdiction to apply the law of a different jurisdiction in lawsuits arising from, say, family law, tort, or contract. The law which is applied is sometimes referred to as the "proper law.
Forum shoppingForum 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.
U.S. stateIn the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside.
Lex lociIn conflict of laws, the term lex loci (Law Latin for "the law of the place") is a shorthand version of the choice of law rules that determine the lex causae (the laws chosen to decide a case). When a case comes before a court, if the main features of the case (particularly the parties and the causes of action) are local, the court will then apply the lex fori, the prevailing municipal law, to decide the case. However, if there are "foreign" elements to the case, the court may then be obliged, under conflict of laws, to consider whether it has jurisdiction to hear the case (see forum shopping).
Personal jurisdictionPersonal jurisdiction is a court's jurisdiction over the parties, as determined by the facts in evidence, which bind the parties to a lawsuit, as opposed to subject-matter jurisdiction, which is jurisdiction over the law involved in the suit. Without personal jurisdiction over a party, a court's 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.
JurisdictionJurisdiction (from Latin juris 'law' + dictio 'declaration') is the legal term for the legal authority granted to a legal entity to enact justice. In federations like the United States, areas of jurisdiction apply to local, state, and federal levels. Jurisdiction draws its substance from international law, conflict of laws, constitutional law, and the powers of the executive and legislative branches of government to allocate resources to best serve the needs of society.
