Public law governs the relationship between individuals and the state. It includes constitutional law, administrative law, and criminal law. It deals with issues that affect the public at large, including governmental authority, legal obligations of public officials, and the functioning of public institutions.
Explanation of other options:
- Civil law: Concerned with disputes between individuals (e.g., contracts, torts, property disputes).
- Substantive law: Defines rights and duties (both civil and criminal) but doesn’t specifically regulate the State's structure.
- International law: Governs relations between nations, not internal state functioning.
