Law is a set of rules that a society or government develops in order to deal with crime, business agreements, and social relationships. The word is also used to describe the people who work in this system, including judges and lawyers. It is a very complex and highly specialised area, but its basic functions are to ensure that all individuals and businesses comply with the rules and that justice is served when these rules are broken.
This is a challenging task given the diversity of human societies and cultures. Laws can be influenced by many factors, from the way that they are perceived to reflect moral values to the specific idiosyncrasies of a particular language or culture. The fact that the law is based on human perceptions rather than natural or scientific principles can make it difficult to prove or disprove theories about the nature of law, although the logical structure of a legal system does provide some means of verifying the correctness of a legal statement.
Nevertheless, there are some important aspects of the nature of law that are inescapable. For example, the law cannot dictate behaviours which are impractical or impossible to achieve, as such a precept would be outside the scope of the law’s authority. Similarly, the law cannot impose burdens which are greater than a person’s capability to carry, as such a requirement would be unenforceable by any legal system.
The complexity of the law extends to a number of areas, such as international law and space law. This is a result of the vast differences between nation-states, which are governed by different types of political systems and laws. The main function of law is to define and enforce the rules that govern the activities of a state or a community, but it also has an important role to play in promoting economic development. In this context, it is vital to regulate the activities of banks, and to insure that investors receive the proper return on their investment.
Another important aspect of the law is the relationship between it and other systems of governance, especially politics. In a democracy, the law is created and enforced by a parliament or other elected body of representatives, which is subject to scrutiny and change through parliamentary elections or referendums. This type of democracy is a major feature of the law, and the concept of democratic rights has become part of the law in many countries.
Other types of governing systems are less democratised, and this is often reflected in the law. The law may be regulated by constitutional, religious or ethnic traditions, and the governing body may have special powers which it must exercise in certain situations. This can give rise to a variety of issues, such as whether the governing body should be subject to law itself, or how to check the legitimacy of decisions made by that body. This issue is particularly problematic when the governing body consists of military or political elites.
