   Qualified negative (Legislation), a limited veto power, by
      which the chief executive in a constitutional government
      may refuse assent to bills passed by the legislative body,
      which bills therefore fail to become laws unless upon a
      reconsideration the legislature again passes them by a
      certain majority specified in the constitution, when they
      become laws without the approval of the executive.

          used with respect to native endowments and general
          ability suited to the performance of a task or duty;
          qualified with respect to specific acquirements and
          training.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

QUALIFIED FEE, estates. One which has a qualification subjoined to it, and
which must be determined whenever the qualification annexed to it is at an
end. A limitation to a man and his heirs on the part of his father, affords
an example of this species of estate. Litt. Sec. 254; 2 Bouv. Inst. n. 1695.
