Law is a set of rules that govern relationships among individuals and social institutions. It is sometimes described as a science or an art. Its scope is broad and it is used in many aspects of daily life. In some countries, laws are governed by constitutions, and they are used to shape politics, history, economy, and society. Law also helps people access justice and protects their rights.

Different types of law apply to different types of people. For example, immigration law deals with rights of foreigners living in the nation-state. It also deals with issues like statelessness and the right to asylum. In addition, there is social security law, which deals with rights to social insurance. Family law, on the other hand, addresses issues concerning marriage and divorce, child custody, and property. Finally, there is transactional law, which deals with businesses.

Law is composed of statutes and case law. Statutes and constitutions outline the rules that govern the country, and case law deals with how courts apply them. The federal government’s courts interpret the Constitution and federal laws. They also make decisions on individual rights and regulations. And the courts can impose sanctions on businesses that violate their laws.

A large part of regulation involves the provision of public services and utilities. The Department of Water and Power regulates water supplies and other utilities. Private companies have been forced to accept certain social responsibilities since privatisation took place. In OECD countries, energy, water, and telecomms are regulated industries.
