  By-law n.
  1. A local or subordinate law; a private law or regulation made by a corporation for its own government.
     There was likewise a law to restrain the by-laws, or ordinances of corporations.   --Bacon.
     The law or institution; to which are added two by-laws, as a comment upon the general law.   --Addison.
  2. A law that is less important than a general law or constitutional provision, and subsidiary to it; a rule relating to a matter of detail; as, civic societies often adopt a constitution and by-laws for the government of their members. In this sense the word has probably been influenced by by, meaning secondary or aside.
