   Usage: {Precedent}, {Example}. An example in a similar case
          which may serve as a rule or guide, but has no
          authority out of itself. A precedent is something
          which comes down to us from the past with the sanction
          of usage and of common consent. We quote examples in
          literature, and precedents in law.
