What Is Law?

Law is the system of rules that a society or government creates in order to ensure a safe and just society. It can refer to a general set of guidelines that governs behavior, such as contracts or business transactions, or it can be applied to specific topics such as criminal behaviour or the rights of a citizen. It can also be used to refer to the people or groups who enforce those guidelines through penalties.

The laws of a nation differ greatly from one to the next, as do the purposes that they serve. Some of the most basic functions include establishing standards, maintaining order, resolving disputes and protecting liberty and rights. Many laws have deeper dimensions, however. For example, a debate continues over whether judges should be free to express their own personal values or beliefs as part of their judgments.

Laws are made by government bodies, which may be sovereign states or local councils. They may be written or unwritten, and they are typically compiled from precedents (case law). The way that different legal systems organize their law can also be complex. Some countries use a common law system, in which the law is derived from judicial decisions, while others, such as Japan, have a civil law system based on the Napoleonic Code and other sources.

Each area of law is defined by the specific requirements in that field. Banking and financial law, for example, sets minimum capital levels that banks must hold, and regulations about best practice in investment. Water and energy laws deal with the management of these essential resources. Aviation law is framed by national civil aviation acts, which are generally aligned with the recommendations or mandatory standards of the International Civil Aviation Organisation or ICAO.

In the case of civil and commercial laws, a judge’s decision on a particular case may bind all subsequent courts in that jurisdiction, according to the principle of stare decisis. This is different from a statute, which may be enacted by a legislature and thus imposes binding authority on all future courts.

The social aspects of law are also important, and this is reflected in areas such as criminal law, where judges have the power to impose fines and imprisonment for a range of offences. Other areas of law include family law, which deals with marriage and divorce; medical jurisprudence; the law of war, which regulates military conflict and the military; and property law, which defines a citizen’s right to property and the conditions under which it can be acquired and held.

While the complexities of law can seem overwhelming, it is a vital part of human life and enables people to interact in a stable and peaceful environment. The law provides a framework for a country to develop, and it can be applied to many issues, from the treatment of immigrants to the ownership of property. In the most stable societies, laws are enforceable and enforced by a sovereign authority, and those who break them are penalised.
