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.
TextualismTextualism is a formalist theory in which the interpretation of the law is primarily based on the ordinary meaning of the legal text, where no consideration is given to non-textual sources, such as intention of the law when passed, the problem it was intended to remedy, or significant questions regarding the justice or rectitude of the law. The textualist will "look at the statutory structure and hear the words as they would sound in the mind of a skilled, objectively reasonable user of words.
Judicial activismJudicial activism is a judicial philosophy holding that the courts can and should go beyond the applicable law to consider broader societal implications of its decisions. It is sometimes used as an antonym of judicial restraint. The term usually implies that judges make rulings based on their own views rather than on precedent. The definition of judicial activism and the specific decisions that are activist are controversial political issues. The question of judicial activism is closely related to judicial interpretation, statutory interpretation, and separation of powers.
Judicial restraintJudicial restraint is a judicial interpretation that recommends favoring the status quo in judicial activities and is the opposite of judicial activism. Aspects of judicial restraint include the principle of stare decisis (that new decisions should be consistent with previous decisions); a conservative approach to standing and a reluctance to grant certiorari; and a tendency to deliver narrowly tailored verdicts, avoiding "unnecessary resolution of broad questions." Judicial restraint may lead a court to avoid hearing a case in the first place.
Statutory interpretationStatutory interpretation is the process by which courts interpret and apply legislation. Some amount of interpretation is often necessary when a case involves a statute. Sometimes the words of a statute have a plain and a straightforward meaning. But in many cases, there is some ambiguity in the words of the statute that must be resolved by the judge. To find the meanings of statutes, judges use various tools and methods of statutory interpretation, including traditional canons of statutory interpretation, legislative history, and purpose.
Judicial reviewJudicial review is a process under which executive, legislative and administrative actions are subject to review by the judiciary. A court with authority for judicial review may invalidate laws, acts and governmental actions that are incompatible with a higher authority: an executive decision may be invalidated for being unlawful or a statute may be invalidated for violating the terms of a constitution. Judicial review is one of the checks and balances in the separation of powers: the power of the judiciary to supervise the legislative and executive branches when the latter exceed their authority.
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.
