The law and business go hand in hand. To run a business- without any or many problems- one has to know and understand the laws and where they came from and how they pertain to your organization. Common law was founded on common sense. But because many do not have common sense, case law and/or civil law has to take place. Let us try to figure out the common law tradition and the sources of the law . Common law tradition originated far from America. “The Common Law Tradition, in general terms, sometimes referred to as Anglo-American Law, is a body of customary law originating in the Common Law courts of Medieval England. The system is based upon judicial decisions which were then published in reports of decided cases”. And this is how the precedent for other cases is defined- all through this tradition of Common Law. First, to understand common law you must understand the law- why it is here and that it keeps changing- as the people needs and wants and technology keep changing. The concept of law is broad. Although it is difficult to state a precise definition, Black’s Law Dictionary states the definition of the law is-“that which must be obeyed and followed by citizens, subject to sanctions or legal consequences; a body of rules of action or conduct prescribed by controlling authority and having binding legal force”. Law, in its generic sense, is a body of rules of action or conduct prescribed by controlling authority, and having binding legal force. That which must be obeyed and followed by citizens subject to sanctions or legal consequences is a law. The definition of common law is common sense law. One has to use common sense and that will always prevail. Common law is uncodified- meaning there is no comprehensive compilation of legal rules and statutes. Civil law is codified- meaning civil law systems have comprehensive, continuously updated legal codes
