This Article charts a “topographical” approach to accountability in migration control, whereby the site of a violation is perceived from a bird’s-eye view and accountability pursued through diverse legal regimes and via a broadened geographic lens. Drawing on scholarship on legal geography, legal black holes, and strategic litigation, we argue that accountability structures may usefully be approached topographically. Rather than advocating for accountability in regard to particular regimes or jurisdictions, the topographical approach offers a general framework for mapping and exploring the full grid of potential accountability mechanisms.
