Transnational intermunicipal cooperation in the EU

Intermunicipal cooperation has become widespread in Europe. Most of them are organized exclusively within the territory of a region or a member state and subject to national rules of administrative law.
However, there has long been a need to extend the scope of action of intermunicipal partnerships to the territory of two or more different states. The regulation of cross-border (intermunicipal) cooperation is also part of the European integration process, as the European grouping of territorial cooperation (EGTC) Regulation tried to facilitate transnational intermunicipal cooperations.
However, numerous legal obstacles and challenges remain. The purpose of the paper is to analyse, from an administrative law perspective, the possible causes of underutilization and pitfalls when using those frameworks and instruments. The administrative law bottlenecks are also tested by means of empirical research against the cross-border cooperation practice.
