What Is Law?
Law is a set of rules that a society or government establishes to regulate behavior and enforce penalties when the rules are broken. There are many different kinds of laws: criminal, civil, constitutional, administrative, and environmental, among others. Laws are used to punish offenders, protect citizens’ rights and freedoms, and promote order and fairness in a society. Laws are also a tool for economic development and social progress.
While laws are necessary for human society, their precise nature is subject to debate. The concept of law has evolved over time and varies from culture to culture. Some nations use a common law system, where the legal framework is derived from judicial decisions (often called case law). Other nations have statutory systems, where the laws are written down by a legislature or other authority.
The laws of a nation vary widely and are influenced by the political and economic environment in which they are developed. In general, countries with a stable political system tend to have well-developed laws. Countries in turmoil often have disorganized or incomplete legal systems.
Generally, the law reflects the values and beliefs of the people who create it. For example, a country’s law may reflect the value of equality and respect for individuals regardless of their race or religion. However, a particular law may be challenged by the people who believe it discriminates against or unfairly treats one group of citizens over another. The principle of equality before the law is fundamental to Western legal systems, though not always adhered to in practice.
Laws are usually written in a legal language that is difficult for ordinary people to understand. For instance, a lawyer might use terms like “precedent” or “evidentiary proof.” Precedent refers to a previous court decision that must be followed by a new court unless it can show that the earlier ruling was wrong or significantly different. Evidentiary proof refers to evidence that supports the claim of a party in a lawsuit. A court’s docket or record consists of brief entries of the acts and proceedings of a trial. A judge might also refer to a decision made by a court of appeals that has the power to review its decisions as a “binding precedent.”
In addition to laws, there are a variety of institutions and professionals involved in interpreting and enforcing the law. These include police, judges, prosecutors, and lawyers. Some of the functions of the legal system are screening applicants for pretrial release, monitoring convicted offenders released on probation, and presenting the facts in a criminal trial. Other important functions of the legal system are determining guilt or innocence, providing compensation, and protecting private property and personal liberties. The law’s relationship to politics is illustrated by the fact that, in most countries, those with military or political power are the ones who make and enforce the laws. However, revolutions against existing political-legal structures are a regular feature of modern society.
