Common law is basically common sense. There is a lot of misconception about common law. For example, some people claim that common law is based on case law and the judges opinion. Others report that it is based on the magna carta when in actuality the magna carta is based on common law. The magna carta can be used as common law if the plaintiff so chooses. It just makes it easier to give bureaucrats something to see in writing since they cannot seem to grasp concepts. While others claim that common law is a combination of statutes and case law.
