This essay aims to describe the contrasting approaches to disability described by international humanitarian law (IHL) and international human rights law (IHRL) with the aim of pointing out the approaches/models of disability underpinning two legal regimes. The limits of those approaches/models in the treatment and protection of persons with disabilities shall be investigated and established. Ultimately, the paper considers the possibility of recommending a unified approach/model that should underpin both IHL and IHRL in addressing aspects of disability.
