  In his review of the international treaties that outlaw discrimination, Wouter Vandenhole finds that “[t]here is no universally accepted definition of discrimination” (2005: 33). In fact, the core human rights documents fail to define discrimination at all, simply providing non-exhaustive lists of the grounds on which discrimination is to be prohibited. Thus, the International Covenant on Civil and Political Rights declares that “the law shall prohibit any discrimination and guarantee to all persons equal and effective protection against discrimination on any ground such as race, color, sex, language, religion, political or other opinion, national or social origin, property, birth or other status” (Article 26). And the European Convention for the Protection of Human Rights declares, “The enjoyment of the rights and freedoms set forth in this Convention shall be secured without discrimination on any ground such as sex, race, color, language, religion, political or other opinion, national or social origin, association with a national minority, property, birth or other status” (Article 14). Left unaddressed is the question of what discrimination itself is.
