Law is a system of rules that are created by authorities and enforced by institutions such as courts and police forces. It regulates human behavior, regulates interactions between institutions and individuals, and establishes procedures for resolving disputes. All systems of law are codified, which means they are written down and published. There are three types of law: criminal law, civil law, and religious law. This category covers the world of law, from criminal convictions to intellectual property rights and everything in between.
