Gegenseitiges Vertrauen als Rechtsprinzip des Unionsrechts.

'Mutual Trust as a General Principle of EU Law': The thesis seeks a dogmatic clarification of mutual trust as a general principle of EU law which applies in any area that is subject to EU law. It also sheds light on the challenges that trust-based cooperation is confronted with in light of the so-called 'polycrisis' of the Union and points out approaches to stabilize trust-based cooperation even in times of crisis.
