Conflict of laws is the set of rules or laws a jurisdiction applies to a case, transaction, or other occurrence that has connections to more than one jurisdiction. This body of law deals with three broad topics: jurisdiction, rules regarding when it is appropriate for a court to hear such a case; foreign judgments, dealing with the rules by which a court in one jurisdiction mandates compliance with a ruling of a court in another jurisdiction; and choice of law, which addresses the question of which substantive laws will be applied in such a case. These issues can arise in any private-law context, but they are especially prevalent in contract law and tort law.
Forum non conveniens (FNC) is a mostly common law legal doctrine through which a court acknowledges that another forum or court where the case might have been brought is a more appropriate venue for a legal case, and transfers the case to such a forum. A change of venue might be ordered, for example, to transfer a case to a jurisdiction within which an accident or incident underlying the litigation occurred and where all the witnesses reside.
Choice 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, 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." Dépeçage is an issue within choice of law.
In contract law, a forum selection clause in a contract with a conflict of laws element allows the parties to agree that any disputes relating to that contract will be resolved in a specific forum. They usually operate in conjunction with a choice of law clause which determines the proper law of the relevant contract.
In conflict of laws, renvoi is a subset of the choice of law rules and it may be applied whenever a forum court is directed to consider the law of another state.
Characterisation, or characterization, in conflict of laws, is the second stage of the procedure to resolve a lawsuit that involves foreign law. The process is described in English law as Characterisation, or classification within the English judgments of the European Court of Justice. It is alternatively known as qualification in French law.
In all lawsuits involving conflict of laws, questions of procedure as opposed to substance are always determined by the lex fori, i.e. the law of the state in which the case is being litigated.
Incidental questions in private international law with respect to the problems and elements discussed below. In the Roman conflict of laws, an incidental question is a legal issue that arises in connection with the major cause of action in a lawsuit. The forum court will have already decided that it has jurisdiction to hear the case and will be working through the next two stages of the conflict process, namely: characterisation and choice of law. For example, the court may classify the cause as "succession", but it notes that the plaintiff brings the claim for relief as the deceased's widow. Before the court can adjudicate on the main issue, it must first decide whether the plaintiff actually has the status claimed, i.e. the incidental question would be the validity of the claimed marriage. The inconvenient reality is that many lawsuits involve a number of interdependent legal issues. In purely domestic cases, this poses no difficulty because a judge will freely move from one domestic law to another to resolve the dispute. But in a conflict case, the question is whether the incidental question is resolved by reference either to its own choice of law rules, or to the same law that governs the main issue. States have not formulated a consistent answer to this question.
In conflict of laws, the choice of law rules for tort are intended to select the lex causae by which to determine the nature and scope of the judicial remedy to claim damages for loss or damage suffered.
Conflict of laws in the United States is the field of procedural law dealing with choice of law rules when a legal action implicates the substantive laws of more than one jurisdiction and a court must determine which law is most appropriate to resolve the action. In the United States, the rules governing these matters have diverged from the traditional rules applied internationally. The outcome of this process may require a court in one jurisdiction to apply the law of a different jurisdiction.
In law, the enforcement of foreign judgments is the recognition and enforcement in one jurisdiction of judgments rendered in another ("foreign") jurisdiction. Foreign judgments may be recognized based on bilateral or multilateral treaties or understandings, or unilaterally without an express international agreement.
In conflict of laws, the term lex loci is a shorthand version of the choice of law rules that determine the lex causae.
The doctrine of the proper law is applied in the choice of law stage of a lawsuit involving the conflict of laws.
In modern society, the role of marriage and its termination through divorce have become political issues. As people live increasingly mobile lives, the conflict of laws and its choice of law rules are highly relevant to determine:
Conflict of marriage laws is the conflict of laws with respect to marriage in different jurisdictions. When marriage-related issues arise between couples with diverse backgrounds, questions as to which legal systems and norms should be applied to the relationship naturally follow with various potentially applicable systems frequently conflicting with one another.
The Hague Convention on the Law Applicable to Trusts and on their Recognition, or Hague Trust Convention is a multilateral treaty developed by the Hague Conference on Private International Law on the Law Applicable to Trusts. It concluded on 1 July 1985, entered into force 1 January 1992, and is as of September 2017 ratified by 14 countries. The Convention uses a harmonised definition of a trust, which is the subject of the convention, and sets conflict rules for resolving problems in the choice of the applicable law. The key provisions of the Convention are:
The Convention on the Law Applicable to Contractual Obligations 1980, also known as the Rome Convention, is a measure in private international law or conflict of laws which creates a common choice of law system in contracts within the European Union. The convention determines which law should be used, but does not harmonise the substance. It was signed in Rome, Italy on 19 June 1980 and entered into force in 1991.
A maritime lien, in English and US law and elsewhere, is a specific aspect of admiralty law concerning a claim against a ship for services rendered to it or injury caused by it.
Tolofson v Jensen, [1994] 3 S.C.R. 1022 is a landmark decision of the Supreme Court of Canada on conflict of laws in tort. The Court held that the primary determiner in selecting a country's law in tort should be the lex loci. The case was decided with Lucas v Gagnon.
Huber v Steiner (1835) 2 Bing (NC) 202 was a judicial decision of the English Court of Common Pleas relating to choice of law issues in connection with a promissory note.
