Contrary to what prevails in the context of the Canadian and Quebec charters of rights, constitutional judges in India and South Africa have clearly recognized the justiciability and enforceability of social and economic rights. To explain this normative phenomenon, the author advance a hypothesis according to which the socio-economic conditions and the level of development of a country and the ideological context in which constitutional standards were adopted and are interpreted constitute factors that inevitably influence the courts and the conception judges have of human beings. The author therefore bring to light the formal conception of the person that Canadian judges promote by over-valuing individual autonomy in the interpretation of sections 7 and 15 of the Canadian Charter of Rights and Freedoms, and note that in countries marked by extreme poverty, the case law on socio-economic rights is more vibrant, since the Indian and South African supreme courts recognize human beings in all their dimensions.
