EPSO EU Treaties & Law Questions

Test your knowledge of EU citizenship, fundamental rights, and the treaty framework that underpins the Union.

What are EU treaties & law questions?

These questions cover the legal foundations of the EU: the Treaty on European Union (TEU), the Treaty on the Functioning of the EU (TFEU), the Charter of Fundamental Rights, and key principles like subsidiarity, proportionality, and conferral. They also test EU citizenship rights.

EPSO often asks about specific treaty articles, when treaties entered into force, and what changes each treaty introduced. The Lisbon Treaty (2009) is particularly important as the most recent major treaty reform.
