Legal Precedent and Stare Decisis
Legal precedent is a judicial decision that is used as an authoritative example in subsequent similar cases within a legal system. It is a cornerstone of common law legal systems, which are systems that derive their laws from judicial decisions and have their roots in the English legal system. The principle guiding the application of legal precedents is known as stare decisis, a Latin term meaning "to stand by things decided." This principle ensures consistency and predictability in the law by obligating courts to follow the rulings of previous decisions.
Stare Decisis
In common law, stare decisis is a central doctrine. It dictates that courts are bound to adhere to the rulings of previous cases when the facts and legal issues are similar. This practice of adhering to precedent ensures legal consistency and facilitates efficient case resolution.
The Supreme Court of the United States has often addressed the importance of stare decisis. For example, in the case of Planned Parenthood v. Casey, the Court underscored the role of stare decisis in maintaining the rule of law. The doctrine is also a subject of discussion among legal scholars and justices, including figures like Louis Brandeis, who emphasized its canonical authority, and Clarence Thomas, who is noted for his skepticism of the doctrine.
Operation and Impact
Legal precedent operates on two levels: horizontal stare decisis and vertical stare decisis. Horizontal stare decisis refers to a court adhering to its own previous rulings, while vertical stare decisis involves a lower court following the decisions of higher courts within the same jurisdiction.
The Federal Supplement is a series of federal court reports that illustrate the application of both horizontal and vertical stare decisis. In contentious legal areas, such as the legal status of fictional pornography depicting minors, precedents set in landmark cases like Ashcroft v. Free Speech Coalition have far-reaching implications.
Precedent in Civil Law Systems
Unlike common law systems, civil law systems do not base their legal rules primarily on judicial decisions or precedent. Instead, they rely on comprehensive legal codes. However, precedent may still influence rulings in civil law jurisdictions to a lesser degree.
Global Perspectives
The application of legal precedent can vary internationally. For instance, the Kosovo independence precedent is often viewed as a unique case rather than a standard for international law regarding secession. In South African constitutional law, the use of precedent is an important aspect of interpreting the country's Constitution.
