What Is Law?

Law is the set of rules that form a framework to ensure a peaceful society. It also defines what is acceptable behavior and punishes those who break the laws. This is why many people consider a career in the legal field to be so appealing.

The word law comes from the Latin lege, which means “to command.” However, the precise definition of law has long been a source of dispute. Some scholars have argued that law is simply an aggregate of rules created and enforced by social or governmental institutions to regulate human behavior. Others have suggested that law should be defined in terms of the principles of justice and fairness.

A country’s laws are governed by the constitution, which outlines how government agencies operate and how citizens can appeal decisions made by those bodies. The law is then implemented by a judiciary, which resolves disputes between people and determines whether or not charged criminals are guilty of committing a crime. A judicial body can also remove laws that are considered unconstitutional.

Civil law covers most issues involving people and their interactions, from the way marriages and divorces are handled to the legality of abortion. It also includes torts, which are disputes that involve damage to property or personhood. Criminal law and civil rights are two other areas of law that deal with specific types of situations.

Property law is a large area of the law and encompasses ownership of land (called real property or real estate) and movable objects (called personal property). It covers mortgages, leases, liens, licences, covenants and easements. Intellectual property and commercial law are other related topics. Medical law is an important area of the law and includes physician-patient privilege, informed consent, negligence and malpractice.

Other areas of the law include immigration and nationality law, which cover the rights of foreigners to live in a nation-state that is not their own and to acquire or lose citizenship; family law, which deals with marriage and divorce proceedings; and the law relating to money and business transactions (called transactional law). The law can be further broken down into specialized fields. For example, biolaw focuses on the intersection of law and the biosciences. Environmental law is a growing field, covering issues such as toxic waste and global climate change. There is also a special branch of law that covers international law, which relates to the rights of nations as they interact with each other and other countries around the world.
