Significant changes can be seen in government and administration in recent years. Internationalisation, economisation, the changed self-image of citizens and new forms of public management are at the forefront. The following article asks, from an administrative science perspective, whether, and if so how, the constitutional and administrative law of Switzerland reflects these changes. It shows that both in constitutional law and in particular in administrative organisation law, and in the Confederation's budgetary planning law, fundamental changes have taken place. Nevertheless, further research and needed legislation are in required if the law is to keep pace with the dynamic developments.
