In a nutshell, law is a system of rules that govern behavior. There are many definitions of law, and some view it as a science, while others consider it an art. In a common-law jurisdiction, laws are formulated by a group of legislators or a single legislator. In other states, laws are created by an executive through decrees, or by judges. Private individuals can also create legally binding contracts or arbitration agreements, as long as these are accepted by the government.


The study of law involves practically all aspects of life. There are three primary categories of law: criminal, civil, and administrative. Labor law involves the tripartite industrial relationship, collective bargaining regulations, and the right to strike. Individual employment law involves the rights of individuals and workplaces. Criminal and civil procedure deal with the rules and procedures of courts. Evidence laws deal with admissible evidence in courts. Lastly, there are many other types of law.

Generally, there are many subfields of law. Small business law deals with regulation of corporate contracts, licensing, and tax classifications. Other areas of business law deal with intellectual property, patents, and securities. Immigration and labor laws are a few of the other areas that include legal matters involving a company’s activities. In addition, there are several other subfields within the field of law. The following are just a few.

Hart focuses on the social fact as a valid law. His concept of law includes secondary rules that determine the validity of the primary rules and how they are applied. As Hart notes, some countries’ legal systems have not served these purposes well. Authoritarian governments repress political opponents, while authoritarian governments oppress minorities and political opponents. The use of laws by colonial powers helped impose peace in countries that were not previously at peace.

A legal system can also serve to protect individuals from majorities or to maintain peace in a nation. In a common-law legal system, the decisions of a court are the same as the decisions of lower courts. The principle of stare decisis ensures that similar cases will be decided in the same manner. In a civil-law system, decisions are more detailed and require more detailed documentation. They only cover one case, but they can have a profound impact on society.

A legal system may be defined as a set of rights that a person can exercise. These rights, or “rights,” can be protected by a statutory law. In the United States, the constitution and statutes protect a person’s rights and liberties, and protect them against unreasonable intrusions. The First Amendment prohibits government from making laws that limit freedom of speech. If an individual believes that their free speech rights have been violated, they may file a lawsuit.
