Abstract The tensions between centralization and autonomy inherent in territorial conflicts can give rise to entrenched positions and stalemate. This Federalism Monitor article describes an attempt in Catalonia to find new ways to resolve the Spanish-Catalan conflict over self-determination, which culminated in a referendum and unilateral declaration of independence in 2017, followed by a backlash by the central authorities, including the suspension of political autonomy. We summarize the context, contents, and potential impact of the Report on the Clarity Agreement (2024). Our analysis draws on our experiences as members of the plural and independent council of academic experts appointed by the Catalan Government to produce the report. This experience, we argue, can guide and inspire other experiences of conflict resolution by offering a description and analysis of this case, which has many generalizable features.
