What Is Law?


Law is a system of rules that governs the actions of people within a nation or a community. A nation’s laws often keep the peace, protect individual rights, maintain the status quo, promote social justice and orderly change, and provide for a fair government.

Legal systems can be found in a variety of cultures, religions, and countries, but they all tend to share the same basic purposes. Some serve these needs better than others, but all provide some level of protection and security for individuals.

Generally, these systems are organized in codification and favor cooperation, order, and predictability over excessive detail or unpredictability. Civil codes are the most popular, but some nations have developed alternative models of governing and lawmaking.

Some forms of law are based on religious precepts and principles, such as Jewish Halakha (law of the Torah) or Islamic Sharia (law of the Quran). Christian canon law also survives in some church communities.

Other forms of law are created by legislatures, mainly in the United States and the European Union, as well as through judicial decisions. For example, laws that prohibit murder and other crimes are made by the government of a country.

A court officer who oversees administrative functions, especially managing the flow of cases through the courts. The clerk’s office is often called a court’s central nervous system.

Evidence law deals with what materials can be introduced in a court case and how they may be used to prove or disprove a plaintiff’s claim or defendant’s defense. It also concerns the procedure that is followed by a judge and jury as they build a case and decide the facts of the dispute.

Criminal law deals with how judges and juries should conduct trials of offenses that are considered serious or of significant public importance. It is a complex area of the law, and a good understanding of it can be essential to effective judicial practice.

Laws can also be designed to help a country’s citizens and businesses. Consumer law, for example, can regulate a company’s ability to set prices or limit the number of competitors it has in a market.

These laws may be written or tacitly accepted by the people as a whole. A constitution, for example, may be a written document that codifies the law of a particular nation or community and encodes its fundamental rights.

In some nations, a written code of laws is created by a legislature, mainly in the United States and the United Kingdom, to provide a legal basis for a country’s government. These documents often reflect the consensus of the governing body and are a valuable source of guidance for all citizens.

Typically, these laws are enacted by the government as laws of the land and can be changed or repealed by a legislature or the executive. They are usually enforceable through courts, and can include a variety of penalties and punishments for violations.

Legal rights are a common element in many nations’ laws and are some of the most important and pervasive building blocks of positive law. They are typically bestowed by legal rules and judicial decisions, but can also be established through unilateral actions intended to create a right, or by agreements (typically contracts) or gifts that bind the parties to abide by the rights.
