In this paper the global stability of a Mathematical model of an Ammensal species with unlimited resources and the enemy species with limited resources is examined by Liapunovís stability criteria. It is extracted by constructing a suitable Liapunovís function for evaluating the global stability of the model at fully washed out state where the mortality rates of both the species are greater than their birth rates respectively.
