The European Court of Human Rights has struggled to integrate the lived experience of migrants into the legal reasoning that underlies a determination of human rights violations. This article introduces the concept of migratory vulnerability in an effort to remedy that shortcoming by making an already existing legal principle fit for the daunting task posed by migration cases. The objective is to preserve (and potentially expand) the legal effects of the principle of vulnerability whilst approximating it to the more consistent conception of vulnerability theorists, which would remove some of its ambiguities and negative side effects.
