Which law interprets statutes and constitutional provisions?

The correct choice is case law, as it refers to the body of law created by judicial decisions made by courts, which interpret statutes and constitutional provisions. When courts render opinions on legal issues, they clarify how laws should be understood and applied in specific circumstances. This process often involves analyzing statutes and constitutional texts, providing a legal backbone that evolves with each judicial ruling.

Case law plays a crucial role in establishing precedents that guide future cases, ensuring consistency in legal interpretations. Through this developed body of legal rulings, the judiciary interprets the meaning and implications of existing laws, shaping how they are applied in real-world scenarios. This ongoing dialogue between statutes and judicial interpretation is essential for the fluidity of the legal system.

The other options, while related to legal contexts, have different functions. Regulatory law, for instance, pertains to rules created by governmental agencies, while constitutional law focuses specifically on the interpretation and application of the Constitution. Statutory law consists of written laws enacted by legislative bodies but does not involve judicial interpretation. Hence, case law is the most fitting answer to the question regarding the interpretation of statutes and constitutional provisions.
