Which legal code covers criminal laws in California?

The Penal Code is the legal code that specifically addresses criminal laws in California. It outlines various criminal offenses, penalties, and general principles of criminal law, including definitions of crimes and the legal procedures relevant to criminal justice. This code serves as a foundational legal framework for the prosecution and defense of criminal cases within the state, establishing rules that govern criminal conduct and the legal processes that follow when laws are violated.

The other options represent different areas of law. The Health and Safety Code primarily governs issues related to public health, safety regulations, and substance control. The Business and Professions Code deals with the regulation of professions and businesses, including licensing requirements. The Welfare and Institutions Code focuses on laws regarding social services, child welfare, and mental health, none of which pertain directly to criminal laws as defined by the Penal Code.
