An association to which section 25 applies is within this subsection if the main object of the association is to enable the benefits of membership (whatever they may be) to be enjoyed by persons of a particular racial group defined otherwise than by reference to colour; and in determining whether that is the main object of an association regard shall be had to the essential character of the association and to all relevant circumstances including, in particular, the extent to which the affairs of the association are so conducted that the persons primarily enjoying the benefits of membership are of the racial group in question.
In the case of an association within subsection (1), nothing in section 25 shall render unlawful any act not involving discrimination on the ground of colour.
