      [1913 Webster]

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.
