Law is a collection of rules governing social and political behavior that can be enforced by governments, courts, or private organizations. It also refers to the profession of advising people about legal matters or representing them in court. The precise definition of Law is a matter of debate, but it generally encompasses the idea that there are certain things that are right and wrong.
Blackstone, for example, defined Law as the judicial decisions made by judges and the “depositories of the common law” and considered the opinions of other judges to be evidence of that law. He argued that judges should not make decisions inconsistent with the law of God or nature and that they should follow established laws in their interpretations of the law.
Another definition of Law is a statement of a natural process in which an event or thing always leads to a particular result. The law of gravity is an example of this. It is considered a law because we can observe the effect and predict its future results, even if the circumstances around the phenomenon change.
A law can also be a power granted to one person by another in which the first party has a legal obligation to fulfill the claim. Such a power is called a claim-right and can be found in all four Hohfeldian positions. However, it is puzzling that rights of one normative kind can violate duties of the same normative sort (such as a legal right to do something that we morally have a duty not to do). This is sometimes described as a paradox.
