Despite the fact that persons with disabilities comprise, according to current statistics, a significant portion of conflict-affected communities and are disproportionately affected by armed conflict, the lack of inclusion in accountability mechanisms for acts amounting to crimes under international law is notable. The Convention on the Rights of Persons with Disabilities (CRPD) provides a framework for mainstreaming inclusive investigation practices and promoting greater accountability, through application of the principles of autonomy, non-discrimination and accessibility. This article makes suggestions for the operationalization of this CRPD framework through specific recommendations for accountability mechanisms, alongside legal opportunities for recognition of crimes affecting persons with disabilities and crimes resulting in disability. A case study of the so-called Islamic State of Iraq and the Levant and persons with disabilities in Iraq is used to illustrate the application of recommendations to ensure that persons with disabilities are no longer the “forgotten victims of armed conflict”.
