The law is very complex and ever-changing, but it is needed to regulate our day to day lives to prevent chaos. These traditions were passed on from generation to generation and at times altered to fit their way of life. These incorporated traditions became the common law. Common Law Common law is case law or judge-made law that is created by the judicial branch of government. Also, common law consist of principles and rules of action created by judges in the course of writing opinions about litigated matters.
Judicial opinions form the basis of our legal system.
The sources of law come from written judicial opinions, statutes and regulations. Common law was considered to be the law of the land. As judges decided more cases according to them, common law became more elaborate and complete. The prior decisions upon which judges interpreted new cases came to be called precedent. The judges devised the principle of stare decisis that bound them to follow these precedents.
