Law is a set of rules and restrictions that a government or other authority enforces to determine right and wrong behavior. This body of rules defines what people can and cannot do, such as stealing or murdering. It also determines what punishment, if any, is owed to offenders. It is a fundamental aspect of human civilization.
Law, in the broadest sense of the word, can refer to any rules that a society or community recognizes as binding on its members. The discipline of law, or the study of it, covers a wide range of topics, from criminal and civil laws to international and family laws. It can also encompass a particular legal system, such as those of China or the United States.
One of the most important aspects of law is the fact that it has to be objective, that is, it has to be universally applicable and applied in all places and times. This is referred to as the rule of law, which contrasts with an autocracy or dictatorship, in which the rulers are above the law.
This principle of objectiveness in law is also reflected in the biblical command not to show favoritism in judgment. This principle is important because it ensures that the judges and other authorities who make the laws will treat all people equally. This is also the principle that underlies most western countries’ constitutions.
A natural process is a law in the sense that it is a scientific rule that explains what will happen under certain circumstances. For example, Boyle’s law describes what will happen to the volume of an ideal gas if its pressure changes but its temperature remains the same.
In the context of law, a legal norm is one that has been formally recognized by a legal institution such as a court or legislature. The legal validity of a norm typically flows from, or is grounded in, other legal norms, or laws (MacCormick 1977: 189-190; Sumner 1987: 68-70; Raz 1970: 162).
For example, a judge may declare that a specific type of contract is not valid, and this determination will have the force of law. Likewise, a governmental agency might establish a set of standards that must be met by an employer in order to qualify for a job.
A legal system is a framework of rules that governs a nation or group of nations and provides the basis for its justice systems, administrative organizations, and economic activities. The system includes the rules that determine how a country’s citizens are treated, as well as its military and police. It can include a body of statutes, regulations, and executive orders that are legally binding. It can also include more informal judicial decisions and customs. These are often based on religious or moral principles. Some are universal, such as the prohibition against stealing, while others are local, such as the customs of a tribe. Legal systems can differ dramatically between different countries.
