What is the significance of case law in the legal system?

Case law holds significant importance in the legal system as it establishes precedents for future cases. When courts interpret laws and reach decisions in individual cases, those rulings can serve as a reference for similar cases that arise later. This principle is known as "stare decisis," which means that lower courts are bound to follow the rulings of higher courts in similar situations. By setting these precedents, case law ensures a degree of consistency and predictability in the application of the law, allowing individuals and attorneys to understand how laws may be interpreted and enforced.

In addition, case law evolves as courts make new decisions, adapting the legal system to changes in society, technology, and public policy. This dynamic nature of case law complements statutory law by filling in gaps and offering clarity where legislation may be vague or ambiguous.

While updating legal procedures, outlining rights, and the relationship to statutory law are important components of the legal system, their roles are distinct from the primary function of case law, which is to create binding precedential decisions that guide future case resolutions.
