Legal realismLegal realism is a naturalistic approach to law; it is the view that jurisprudence should emulate the methods of natural science, that is, it should rely on empirical evidence. Hypotheses must be tested against observations of the world. Legal realists believe that legal science should only investigate law with the value-free methods of natural sciences, rather than through philosophical inquiries into the nature and meaning of the law that are separate and distinct from the law as it is actually practiced.
Comparative lawComparative law is the study of differences and similarities between the law (legal systems) of different countries. More specifically, it involves the study of the different legal "systems" (or "families") in existence in the world, including the common law, the civil law, socialist law, Canon law, Jewish Law, Islamic law, Hindu law, and Chinese law. It includes the description and analysis of foreign legal systems, even where no explicit comparison is undertaken.
Codification (law)In law, codification is the process of collecting and restating the law of a jurisdiction in certain areas, usually by subject, forming a legal code, i.e. a codex (book) of law. Codification is one of the defining features of civil law jurisdictions. In common law systems, such as that of English law, codification is the process of converting and consolidating judge-made law or uncodified statutes enacted by the legislature into statute law. Ancient Sumer's Code of Ur-Nammu was compiled circa 2050–1230 BC, and is the earliest known surviving civil code.
Law and economicsLaw and economics, or economic analysis of law, is the application of microeconomic theory to the analysis of law, which emerged primarily from scholars of the Chicago school of economics. Economic concepts are used to explain the effects of laws, to assess which legal rules are economically efficient, and to predict which legal rules will be promulgated.
Legal formalismLegal formalism is both a descriptive theory and a normative theory of how judges should decide cases. In its descriptive sense, formalists maintain that judges reach their decisions by applying uncontroversial principles to the facts; formalists believe that there is an underlying logic to the many legal principles that may be applied in different cases. These principles, they claim, are straightforward and can be readily discovered by anyone with some legal expertise. Supreme Court Justice Oliver Wendell Holmes Jr.
Constitutional economicsConstitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics.
OriginalismIn the context of United States law, originalism is a theory of constitutional interpretation that asserts that all statements in the Constitution must be interpreted based on the original understanding. This concept views the Constitution as stable from the time of enactment and that the meaning of its contents can be changed only by the steps set out in Article Five. This notion stands in contrast to the concept of the Living Constitution, which asserts that the Constitution should be interpreted based on the context of current times, even if such interpretation is different from the original interpretations of the document.
De factoDe facto (deɪ_ˈfæktoʊ,_di-,_də- ; de facto deː ˈfaktoː, in fact) describes practices that exist in reality, regardless of whether they are officially recognized by laws or other formal norms. It is commonly used to refer to what happens in practice, in contrast with de jure ("by law"), which refers to things that happen according to official law, regardless of whether the practice exists in reality. In jurisprudence, it mainly means "practiced, but not necessarily defined by law" or "practiced or is valid, but not officially established".
Living ConstitutionThe Living Constitution, or judicial pragmatism, is the viewpoint that the U.S constitution holds a dynamic meaning even if the document is not formally amended. The Constitution is said to develop alongside society's needs and provide a more malleable tool for governments. The idea is associated with views that contemporary society should be considered in the constitutional interpretation of phrases. The Constitution is referred to as the living law of the land as it is transformed according to necessities of the time and the situation.
Legal historyLegal history or the history of law is the study of how law has evolved and why it has changed. Legal history is closely connected to the development of civilisations and operates in the wider context of social history. Certain jurists and historians of legal process have seen legal history as the recording of the evolution of laws and the technical explanation of how these laws have evolved with the view of better understanding the origins of various legal concepts; some consider legal history a branch of intellectual history.
