Law is a system of rules enforced by social or governmental institutions to regulate behavior and has been described as both a science and an art. It is a foundation for societies and has been central to political life for millennia. Law is a subject of scholarly inquiry in the fields of history, philosophy and sociology, as well as an important source for public policy debate.
Despite its centrality, the definition of law is complex and varied. In its most fundamental sense, it is a set of social precepts that are accepted as binding by a community and enforced through the coercive power of the state. It also serves multiple purposes – establishing standards, maintaining order, resolving disputes and protecting rights and liberties.
A key challenge of the study of law is to understand how it relates to other normative domains such as morality, religion or social conventions. These are often similar in nature to laws but differ from them in that they can be formulated in the form of principles and injunctions rather than as prohibitions and commands.
While there are many different theories of law, they are generally categorized into two broad areas: natural and normative. Natural laws are empirical in nature and can be proven scientifically, such as the law of gravity or the law of supply and demand. Normative laws, on the other hand, are based on an evaluation of the moral and ethical aspects of human behaviour. These cannot be proven with certainty, and they are not as objectively meaningful as the laws of nature.
For example, a court decision imposing a fine on an individual for speeding is an expression of the rule of law and a natural law but does not have the same objective validity as a legislative statute. The distinction is based on the difference in how law is constructed and the types of goals it seeks to achieve.
Depending on the purpose of the law, it may be established by a group or a single legislature, resulting in statutes; by the executive through decrees and regulations; or judicially through the principle of stare decisis (to stand by previous decisions). In common law systems, court judgments are explicitly recognized as law and placed on an equal footing with legislative statutes and administrative regulations.
Many of the world’s cultures have laws and a legal system that provides a structure for people to live together in peace and harmony. For example, criminal law deals with behaviour that disrupts society and may result in imprisonment or fines; while civil law regulates the resolution of lawsuits between individuals or organisations. International law concerns the relations between states, including international treaties and agreements. Other branches of law include commercial law, family law, immigration law and biolaw. It is important for students of law to select an area of research that resonates with their passion and enthusiasm. This will make the learning journey more rewarding and enjoyable.
