Conflict of laws refers to the body of law that resolves problems arising from the differences between legal systems. It is particularly pertinent in the United States, where many states have their own unique laws. Conflict of laws principles determine which jurisdiction's laws apply when there are competing legal rules, and they are especially important in cases involving contracts, torts, family law, and business disputes. The conflict can be between federal and state laws, among state laws, or between the laws of different countries. While there are no universal principles, there are international norms regarding jurisdiction, such as the principle of territoriality.

International conflicts of law
The term "conflict of laws" is primarily used in the United States, Canada, and, increasingly, the United Kingdom. On the other hand, the term private international law is more commonly used in other countries, including Switzerland and those with civil law systems. This term emphasises the differences between national legal systems, but it does not imply the existence of an international body of rules to bridge these differences. Instead, it refers to the portions of domestic private law that apply to international issues.
The "law of the conflict of laws" aims to resolve problems arising from the diversity of courts and laws across jurisdictions. While each country's legal system reflects its society's values, international conflicts of law recognise that nations are wholly sovereign within their borders and cannot be compelled to enforce foreign laws in their own courts. This principle of comity, recognised in many states, underpins the rational functioning of international conflicts of law.
To address international conflicts of law, jurisdictions consider three broad topics. The first is jurisdiction, which determines when a court can hear a case involving multiple jurisdictions. The second is foreign judgments, establishing when a court in one jurisdiction must comply with the ruling of another jurisdiction. The third is the choice of law, which addresses which substantive laws will be applied in a case with cross-border implications.
While there is no universal set of principles for international conflicts of law, consistent international norms have emerged in the theory regarding jurisdiction. Recognised bases of jurisdiction in international law include territoriality, where a country has jurisdiction over occurrences within its territorial boundaries. However, it's important to note that the applicability of these principles can vary based on the specific circumstances and the legal systems involved.

Enforcement of judgements
Conflict of laws, also known as private international law, pertains to the resolution of problems resulting from the diversity of courts and laws. It deals with legal situations or events that are not confined to a single country or jurisdiction, such as marriage, decedents' estates, torts, and business transactions.
When a legal problem involves multiple countries, one of the critical issues is the enforcement of judgements. This involves recognising and enforcing the ruling of a court in one jurisdiction in another jurisdiction. Each country's legal system reflects its societal values, resulting in variations in national laws and judicial structures.
In the context of enforcement of judgements, the principle of comity is significant. Comity refers to the recognition and enforcement of another state's laws and judgements, acknowledging their sovereignty. Many nations, including the United States of America and Australia, have incorporated the principle of comity into their constitutions.
To address enforcement, conflict of laws considers three main aspects: jurisdiction, foreign judgments, and choice of law. Jurisdiction determines when a court can exercise its authority over a foreign defendant or a dispute with minimal connection to the court's jurisdiction. Foreign judgments focus on the rules by which a court in one jurisdiction enforces the ruling of another jurisdiction. Finally, the choice of law addresses which substantive laws will be applied in a case involving multiple jurisdictions.
The recognition and enforcement of foreign judgements are crucial, especially in cross-border litigation. For example, in the English legal system, courses on Conflict of Laws aim to provide an understanding of the enforcement of foreign judgements and their effect within the English legal order.

Choice of law
There are several approaches to determining the choice of law. Classic theories of conflicts law used a number of connecting factors to determine the territorially applicable law. In matters of family law, Anglo-American law used the parties' domicile (narrowly defined). In civil-law countries, by contrast, a person’s nationality was the most important connecting factor. However, due to the influence of the Hague Conference on Private International Law, the reference is now more commonly to the law of a person’s “habitual residence”.
Another approach, known as the better-law approach, attempts to determine which of two potentially applicable laws is better as a solution to the problem at hand. The "traditional approach" looks to territorial factors, such as the domicile or nationality of the parties, where the components comprising each cause of action occurred, and where any relevant assets are located. It then chooses the law or laws with the greatest connection to the cause(s) of action.
In the United States, new approaches to the choice of law began to emerge in the 1950s, starting with the governmental-interest analysis developed by the American legal scholar Brainerd Currie. Currie's approach sought to determine whether a "true" or "false" conflict exists between the law of the forum state and that of the other involved state. A false conflict exists if the laws of both states do not differ; if, though ostensibly different, both laws are designed to effectuate the same policy; or if one law is construed to be inapplicable to cases such as the one before the court. In cases of "true conflict", Currie called for the application of forum law.

Jurisdiction
Conflict of laws deals with three broad topics: jurisdiction, foreign judgments, and choice of law. Jurisdiction here refers to the rules determining which jurisdiction's laws apply when there are competing legal rules. This is also referred to as the "horizontal" choice of law. The rules can be complex, particularly in federal states where there may be different laws in each state or province, and where federal courts must follow a different set of rules to state courts. In the US, for example, federal jurisdiction is limited by the constitution, and federal courts must follow state conflict of laws rules.
There are several principles that guide the determination of jurisdiction in cases with competing legal rules. Lex fori, for example, uses the law of the court's jurisdiction for procedural matters, while Lex loci uses the law where the action occurred for substantive matters. In the EU, choice of law clauses are governed by the Rome I Regulation. In the US, the Full Faith and Credit Clause mandates that states must respect and enforce judgments from other states, except in penal law matters.
The determination of jurisdiction in cases with connections to multiple jurisdictions has evolved over time. In medieval Europe, local laws governed different territories, and in the 17th century, Dutch legal scholars contributed to the development of the jurisprudence of conflict of laws, asserting the sovereignty of nations within their borders. The expansion of international trade in the 19th and 20th centuries further emphasised the need for legal frameworks to manage disputes involving multiple jurisdictions.

Party autonomy
Conflict of laws refers to the body of law of each country or state that is designed to resolve problems arising from the differences between legal systems. The term primarily refers to rules that are solely national in origin and are explicitly not part of international law.
The principle of party autonomy allows the parties to a contract to select the law most appropriate to their transaction. This judicial acceptance of subjective intent excludes the traditional reliance on objective connecting factors. Party autonomy enhances certainty and predictability within the parties' primary contractual arrangement and recognises that parties to a contract may be in the best position to determine which set of legal principles is most suitable for their transaction.
The doctrine of party autonomy is particularly relevant in the context of internet-based commerce, where parties may not know each other or read each other's standard terms. In such cases, the parties are likely to begin performing their obligations based on their interpretation of the contract terms. If a dispute arises, the court or arbitrator will need to refer to the parties' choice of governing law, which may be complicated by the existence of contradictory terms.
The application of the party autonomy principle in resolving disputes varies across jurisdictions. For example, in Australia, courts have referred to the chosen law to resolve disputes in some cases, while in others, they have preferred to refer to the law of the forum (lex fori) to resolve issues related to contract formation, offer and acceptance, and the genuineness of consent.
The Hague Conference on Private International Law (HCCH) encourages the spread of the party autonomy concept to states that have not yet adopted it or have done so with significant restrictions. They believe that the advantages of party autonomy are significant and can serve as a guide to "best practices" in establishing and refining a comprehensive choice-of-law regime.

Frequently asked questions
The "law of the conflict of laws" pertains to the resolution of problems resulting from the diversity of courts and law. Each country's legal system reflects its societal values, and as such, national laws and domestic judicial systems vary. Conflict of laws principles determine which jurisdiction's laws apply when there are competing legal rules.
Conflict of laws can arise between federal and state laws, different state laws, or international laws. For example, in the US, federal courts follow state conflict of laws rules and must respect and enforce judgments from other states, except in penal law matters.
The principle of comity is the idea that every state is sovereign and that the most just exercise of one state's authority may be through the recognition and enforcement of another state's laws and judgments. This principle is written into the constitutions of some countries, such as the USA and Australia.
