  • (n.) A reference to decided cases, or books of authority, to prove a point in law.

Null


Definition:

  • (a.) Of no legal or binding force or validity; of no efficacy; invalid; void; nugatory; useless.
  • (n.) Something that has no force or meaning.
  • (n.) That which has no value; a cipher; zero.
  • (v. t.) To annul.
  • (n.) One of the beads in nulled work.
