Understanding the vocabulary of foreign, comparative, and international law is helpful before approaching research. The following are basic working definitions of foreign, international, and comparative law.
Foreign Law
In legal research in the US, foreign law, or national law, refers to the domestic laws of a particular country. It is comprised of constitutions, statutes, regulations, and depending on jurisdiction, cases. An understanding of global legal systems is essential when conducting research outside of the US. Familiarity with the legal frameworks, sources of law, and judicial processes in different countries will help you navigate and interpret foreign legal materials effectively. It is generally accepted that there are five main legal systems: civil law, common law, customary law, religious law, and mixed legal systems. Mixed legal systems mean that there are features of two or more legal systems present in the same jurisdiction.
International Law
Public international law oversees relationships among governments and international organizations, while private international law (also known as conflict of laws) pertains to cross-border legal disputes between individuals.
Public international law does not have a single source. Instead, the International Court of Justice identifies four sources of international law according to Article 38 of its foundational statute: international conventions (treaties) whether general or particular, establishing rules expressly recognized by the contesting states; international custom, as evidence of a general practice accepted as law; the general principles of law recognized by civilized nations; and subject to the provisions of Article 59, judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.
Comparative Law
Comparative law is an approach to legal inquiry that involves the examination and analysis of legal systems across different countries or jurisdictions. This method seeks to uncover similarities, differences, and patterns within various legal frameworks, aiming to draw insights that can advance legal scholarship and practice. Researchers in comparative law delve into the legal principles, doctrines, jurisprudence, and often the cultural and historical contexts that shape these systems. In practice, conducting research in comparative law often resembles foreign law research, where the focus shifts to comprehending the intricacies of the legal systems of specific jurisdictions.
