Public law refers to a certain type of law or a category of law that governs the relationships between individuals (legal persons or citizens) and the state. This category of law can be subdivided into Administrative law, constitutional law, and criminal law. The constitutional law governs the state i.e., the executive, judiciary, and legislative. The administrative law governs all the administrative agencies of a particular government. The criminal law pertains to crime and punishment in order to strengthen social order.
Private law, on the other hand, is a category of law that pertains to the relationships between individuals i.e., private persons, citizens, and corporations. This type of law governs the legal relations between companies and people under contracts. Another name for private law is civil law. As a result, it addresses civil issues and helps to protect the civil rights of individuals that are under any contractual obligation. Unlike public law that is broad in its scope, private law is narrow.
