This article argues that within the context of settler colonialism, the goal of transitional justice must be decolonisation. Settler colonialism operates according to a logic of elimination that aims to affect the disappearance of Indigenous populations in order to build new societies on expropriated land. This eliminatory logic renders the death of Indigenous peoples “ungrievable”. Therefore, this article proposes a decolonising transitional justice premised on a politics of grief that re-conceptualises Indigenous death as grievable, posing a challenge to the logic (...) of elimination and advancing a “decolonisation of the mind”, and resists a purely affective concept of grief in order to mobilise grief as a political resource to demand transformative structural justice. This article consider deaths at Canada’s Indian Residential Schools as a case study of ungrievability under settler colonialism and the Project of Heart as an illustration of a decolonising form of informal transitional justice.
