Both contracting parties in principle take responsibility for the application and implementation of the Swiss-EU bilateral agreements or of the political declarations of intent on their respective sovereign territories. In Switzerland, the agreements are implemented by the federal offices which have primary responsibility (supported by the Directorate for European Affairs DEA which has co-responsibility). In areas where cantonal competencies are involved, the cantons are responsible for implementation.
