The question "What is law?" has troubled people for many years. Many definitions of law exist for our purposes; however, law can be defined as the rules and regulations made and enforced by government that regulate the conduct of people within a society.
As a child, you learned about rules first at home and later at school. At home, your parents or guardians made and enforced rules concerning issues such as chores and bedtimes. Later teachers and principals established rules about behavior in school, Rules made and enforced by the government are called laws. The government makes laws that affect almost every aspect of daily life.
Everything is certain: Every society that has ever existed has recognized the need for laws. These may have been unwritten, hut even preindustrial societies had rules to regulate people's conduct. Without laws, there would be confusion and disorder. This point does not mean that all are fair or even good, but imagine how people might take advantage of one another without rules.
Democratic system of government cannot function effectively unless its laws are known and inspected by the people the laws are intended to govern. In other words, society must be based on “rule of law” The rule of law requires that the rules by which we are governed be known in advance and created through democratic processes. Rules should not he made up after the fact by arbitrary actions or decrees. All members of society - average citizens and government officials such as senators, judges, and even the president - are required to support the legal system and obey laws.
Here rule of law exists, no one is above the law.
