According to the well-known “claimability objection” posed by O’Neill, it is unjustified to hold that each individual has a human right to socioeconomic goods because the duty-bearers are not sufficiently determined. Even though this objection has been defended in the literature from many counter-arguments, at-tacks against the claimability objection based on non-conventional conceptions of human rights remain unexplored. In this paper, I aim to fill this significant gap in the philosophical literature. I defend the claimability objection from arguments that aim to undermine such an objection on the basis of non-conventional conceptions of human rights. By doing so, I reinforce the defence of the claimability objection.
