  POSSESSORY ACTION, old Eng. law. A real action in which the plaintiff called 
  the demandant, sought to recover the possession of lands, tenements, and 
  hereditaments. On account of the great nicety required in its management, 
  and the introduction of more expeditious methods of trying titles by other 
  actions, it has been laid aside. Finch's Laws, 257; 3 Bouv. Inst. n. 2640. 
       2. In Louisiana, by this term is understood an action by which one 
  claims to be maintained in the possession of an immovable property, or of a 
  right upon or growing out of it, when he has been disturbed: or to be 
  reinstated to that possession, when he has been divested or evicted. Code of 
  Practice, art. 6; 2 L. R. 227, 454.
