What are decisions of the highest court in a state an example of?

Decisions of the highest court in a state are an example of common law. Common law is developed through judicial decisions rather than through legislative statutes or executive branch action. It consists of principles and rules established through court rulings, and these decisions create binding precedents that lower courts must follow. As the highest court interprets and applies laws, its decisions contribute to the evolving body of common law, guiding future cases and establishing legal principles that affect both the courts and the public.

Conversely, statutory law is comprised of laws enacted by a legislative body, and administrative law involves regulations created by governmental agencies. International law governs the relationships between nations rather than domestic legal matters. Thus, the classification of state court decisions as common law highlights their role in shaping legal precedents and interpretations within a state's judicial system.
