LawLaw is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions.
Judicial interpretationJudicial interpretation is the way in which the judiciary construes the law, particularly constitutional documents, legislation and frequently used vocabulary. This is an important issue in some common law jurisdictions such as the United States, Australia and Canada, because the supreme courts of those nations can overturn laws made by their legislatures via a process called judicial review.
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.
Purposive approachThe purposive approach (sometimes referred to as purposivism, purposive construction,Bourchard, Ron A. Living Separate and Apart is Never Easy: Inventive Capacity of the PHOSITA as the Tie that Binds Obviousness and Inventiveness in Pharmaceutical Litigation'. University of Ottawa Law & Technology Journal, January 2007 (Canada) purposive interpretation, or the modern principle in construction) is an approach to statutory and constitutional interpretation under which common law courts interpret an enactment (a statute, part of a statute, or a clause of a constitution) within the context of the law's purpose.
PrecedentPrecedent or stare decisis is a principle or rule established in a previous legal case relevant to a court or other tribunal when deciding subsequent cases with similar issues or facts. Common-law legal systems often view precedent as binding or persuasive, while civil law systems do not. Common-law systems aim for similar facts to yield similar and predictable outcomes, and observing precedent when making decisions is the mechanism to achieve that goal.
