The de:border migration justice collective is a group of movement lawyers and researcher-activists engaging in collaborative research, advocacy, and legal interventions. We mobilise law to resist and challenge the systemic harms caused by the structural violence of physical and other borders, including those enshrined in and perpetrated through legal systems. Centering critical approaches to research, advocacy and litigation, de:border challenges border violence and its normalisation, pursuing accountability and transformation of the systems of oppression that produce and perpetuate rightlessness, racial and other socio-economic inequalities, and injustices that intersect with free movement and migratory rights.
