What a Legal Authority
A Rational-legal authority is commonly referred to as authority or legal authority is a form of leadership in which the authority of a ruling tied other to legal rationality 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, its advantageous to look at the issue and determine an authority. Therefore if it happens a guard the judges can dispense with considering evidence and documentation, from example; if a trader entices you to his shop with an offer that does not exist and then proceeds to sell you somthing you had never heard of, sought nor wanted that is “bait and switch” a band practice, therefore an authority which others can rely upon is reporte. 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.
If we have the benefit of well thought out authorities and the law wanting to deliver constant fairness will apply previous authorities unless they are flawed.
