Interest Representatives' Obligation to Register in the Transparency Register: EU Competences and Commitments to Fundamental Rights

The following study examines whether the EU is entitled to the powers to apply regulations that oblige interest representatives to register in the Transparency Register. The limitations that apply by virtue of fundamental rights to the application of such regulations will also be outlined. The study arrives at the conclusion that an obligation to register could only be established on the basis of Article 352 of the Treaty on the functioning of the European Union. Compliance with fundamental rights depends on the scope of application, the nature of the obligations and the sanctions.
