Abstract

One of the main questions Gillian Brock takes up in Justice for People on the Move (2020) is whether it is morally permissible for states to enact migration policies that discriminate on the basis of religion against those who wish to enter. The main focus of her discussion is on the United States context, and, in particular, the so-called ‘Muslim Ban’ enacted by President Donald Trump in 2017. While Brock offers a powerful critique of this policy, I argue that it is insufficient on its own to support her claim that migration policies that discriminate on the basis of religion in general undermine the legitimacy of the states that enact them. I argue that this claim can be supported within her framework by showing that such policies necessarily display disregard for the human rights of existing members of the discriminating state. I conclude with some reflections on the strength of this account of the moral impermissibility of religious discrimination at the border.
