Nullity \Nul"li*ty\, n.; pl. {Nullities}. [LL. nullitias, fr. L.
   nullus none: cf. F. nullit['e] . See {Null}.]
   1. The quality or state of being null; nothingness; want of
      efficacy or force.

   2. (Law) Nonexistence; as, a decree of nullity of marriage is
      a decree that no legal marriage exists.

   3. That which is null.

            Was it not absurd to say that the convention was
            supreme in the state, and yet a nullity ?
                                                  --Macaulay.
