This Article develops what we call a “topographical approach” to accountability in migration control. Drawing on different strands of scholarship, including legal geography, “legal black holes,” and work on strategic litigation, we approach accountability by perceiving the site of a violation from a bird's-eye view and mapping different accountability structures across diverse legal regimes and via a broadened geographic lens. Rather than advocating for accountability in regard to particular regimes or jurisdictions, we argue that multi-pronged approaches are likely to remain the best starting point for ensuring accountability for human rights violations in the context of current migration control practices. The topographical approach thus offers a general framework for identifying existing blind spots, critically assessing existing trajectories, as well as exploring the wider grid of potential accountability mechanisms.
