All aspects of law possess scaler elements, but critiques from the ‘politics of scale’, a concept well established in political geography, remain rare in legal analysis. Brexit, especially as regards Northern Ireland, provides a key opportunity to consider scaler analysis both in a descriptive and theoretical sense. Scale deepens our understanding of how law co-constitutes multiple scales but also highlights where a flat understanding of law tied to vertical jurisdictional frames foils attempts to garner a full understanding of its operation. Northern Ireland, a legal and political space that from one perspective lends itself to an apparently clear-cut vertical description of legal scales, actually presents a rich space where networked, rhetorical and nodular scales and structures continuously (re)contest scaled solutions. The Brexit outcome of what used to be known as the Protocol on Ireland/Northern Ireland and is now known as the Windsor Framework – and specifically how the Framework is intended to operate in practice – provides an opportunity to not only understand Northern Ireland within a scale and law frame, but also to highlight the shortcomings of law's traditional scaler approach and what lessons may be learned when analysing or engaging with the intersection of law and politics in similar future situations.
