Would the rights of the poor be poor rights? Acknowledging the legally binding character of fundamental social rights (or their juridicité) is one thing; fully recognising the possibility for rights holders to claim effective protection and remedy before the court (or “justiciability”) is another. If the former has become indisputable, the latter is still debated. This chapter examines the recognition of the legally binding character of socio-economic rights, and raises the general problem of the justiciability of such rights. While describing the long way to justiciability in France, it also sheds further light on the ongoing constitutionalisation of these rights, provides a comparative overview of the growing body of jurisprudence related to their protection, and focuses on the special case of the right to decent housing (enshrined in the legislation and enforceable). It also examines the importance of the various academic initiatives taken to convey a better sense of how the adjudication of social and economic rights operates in practice.
