What is a Legal Authority?
A rational legal authority, commonly referred to as an authority or legal authority, is a form of leadership in which the authority of a ruling is tied to another to legal authority which has been established.
To explain, if a case comes before the court and it contains a set of circumstances which are known to have occurred in the past and are more likely than not will occur in the future, it's advantageous to look at the issue and determine an authority. Therefore if it happens again the judges can dispense with considering evidence and documentation. Example: if a trader entices you to his shop with an offer that does not exist and then proceeds to sell you something you had never heard of, sought nor wanted; that is “bait and switch” a banned practice, therefore an authority which others can rely upon is reported. That authority if delivered by the High Court will impart a duty on the lower courts to rely upon it, however, the higher courts may rule differently setting a higher authority, which the lower and higher courts must rely upon.
