Which of the following is NOT one of the recognized origins of law?

The answer identifying "International" as not being one of the recognized origins of law is appropriate because the primary categories of law in the context of the question primarily include sources strictly pertaining to domestic law.

Constitutional law originates from the Constitution, providing the foundational legal framework within a jurisdiction. Statutory law is derived from statutes, which are laws enacted by legislative bodies. Case law, also known as judicial law or common law, comes from court decisions and interpretations which set precedents for future cases.

While international law indeed exists, it typically operates at a different level, focusing on agreements and treaties between nations rather than domestic legal sources applicable to a particular state. Therefore, in this context, international law does not fit into the traditional framework for sources of domestic law recognized within a specific legal system like California's, making it the best choice for this question.
