[A] particular social group means (1) a natural or non-natural group of persons with (2) similar shared background, habits, social status, political outlook, education, values, aspirations, history, economic activity or interests, often interests contrary to those of the prevailing government, and (3) sharing basic, innate, unalterable characteristics, consciousness and solidarity, or (4) sharing a temporary but voluntary status, with the purpose of their association being so fundamental to their human dignity that they should not be required to alter it.
This test was approved by La Forest J, writing for the Supreme Court of Canada in Attorney-General (Canada) v Ward [10] . His Lordship refined the "possible categories" emerging from the application of the "particular social group" criterion to three, after taking into account "the general underlying themes of the defence of human rights and anti-discrimination that form the basis for the international refugee protection initiative" [11] . The three categories which La Forest J discerned were [12] :
(1) [G]roups defined by an innate or unchangeable characteristic; (2) groups whose members voluntarily associate for reasons so fundamental to their human dignity that they should not be forced to forsake the association; and (3) groups associated by a former voluntary status, unalterable due to its historical permanence. The first category would embrace individuals fearing persecution on such bases as gender, linguistic background and sexual orientation, while the second would encompass, for example, human rights activists. The third branch is included more because of historical intentions, although it is also relevant to the anti-discrimination influences, in that one's past is an immutable part of the person.
