Nothing in this Part renders unlawful discrimination against a person on the ground of disability, being discrimination consisting of the exclusion of the person from a sporting activity--
(a) if the person is not reasonably capable of performing the actions reasonably required in relation to the sporting activity, or
(b) if the persons who participate or are to participate in the sporting activity are selected by a method which is reasonable on the basis of their skills and abilities relevant to the sporting activity and relative to each other, or
(c) if the sporting activity is conducted only for persons who have a particular disability and the person does not have that disability.
