      itself with trifles; -- a principle of law, that even if a
      technical violation of a law appears to exist according to
      the letter of the law, if the effect is too small to be of
      consequence, the violation of the law will not be
      considered as a sufficient cause of action, whether in
      civil or criminal proceedings.
