Law is a system of rules enforced by governmental and social institutions. Its various purposes include maintaining peace, protecting minorities from majorities, promoting social justice, and providing orderly social change. Some legal systems are more effective at serving these purposes than others. For example, authoritarian governments often use the law to oppress minorities and political opponents. In the early years of colonialism, European powers used law to impose peace in their colony. In the 20th century, legal systems evolved to incorporate utilitarian theory.
Law affects almost every aspect of human life. Its three basic branches are civil law, criminal law, and evidence law. Civil law deals with the rights of citizens, such as a right to trial and to a fair trial, while criminal law deals with court procedures and admissible evidence. As you can see, there are numerous sub-branches of law.
The court system also plays a vital role in maintaining the rule of law. It is also a mechanism to address grievances and disputes of minority groups and opinions. It is a vital element of American government and ensures that all citizens have access to justice. Although there are various types of courts, the administrative office of the U.S. Courts provides information and educational materials on the rule of law. However, it is important to note that the AO does not provide legal advice or commentary on pending cases.
The United States has a strong tradition of anti-trust laws. These laws protect consumers and companies from unfair trade practices. Competition law traces back to Roman decrees that forbid price fixing and has developed into modern anti-monopoly laws. Consumer law, which regulates advertising and unfair contractual conditions, is another form of competition law.
