Since the turn of the century, the Commission has famously litigated ever fewer infringement cases. When the Commission was still increasing the number of cases, MS did not respond with more opposition right away. Later on, they continued to oppose the […]

MS also increasingly litigated against EU-level implementation decisions until the early 2000s, when the Commission relaxed its control over agricultural policy and subsidies. These policy areas are responsible for 3/4 of all annulment cases against the EU […]

EU legislation is subject to increasing legal mobilization in response to the pooling and delegation of law-making powers to the EU. Recently, mobilization has plateaued, but this may change as the new MS grow more confident. The corresponding annulment […]

The take-home message: Overall, mobilization against EU legislation, implementation, and enforcement is growing, but the salience and polarisation of the respective Court proceedings depends on how much authority the EU wielded in these domains in different […]

This work is the result of a truly inspiring interdisciplinary journey that began almost three years ago.
Thanks to @detershenning.eupolicy.social.ap.brid.gy, we found a research angle that allowed us to combine #politicalScience and #legalscience perspectives to explore MS litigation activity.

By analysing annulment and infringement cases involving Member States between 1954 and 2022, we observe that mobilisation against EU legislation, implementation is overall growing. We note that the number of governmental interventions and polarisation depend on the scope of authority transferred.

In our article, we ask whether the transfer of authority to EU institutions shapes Member States' legal contestation before the @eucourtofjustice.bsky.social. How do national governments mobilise against the transfer and exercise of EU authority?

In "Authority transfer and governmental legal contestation before the court of justice of the EU", @jonasbornemann.bsky.social and I ask a simple question. Does the transfer of authority to EU institutions shape Member States' (MS) legal contestation before the Court of Justice of the EU? We […]

The #EU Commission has proposed letting member states drop the ‘connection requirement’ from the ‘safe third country’ concept in #asylum cases.

@gaiaromeo.bsky.social and I argue this seemingly technical tweak marks a major shift — toward an ‘(un)safe fourth country’

The annual department uitje is a wonderful tradition; a one-day trip to explore the countryside around Groningen. This year’s destination: Schiermonnikoog! A day at the beach, but as you can see… academic discussions never stop! 🌊📚

The EU’s return & ‘safe country’ proposals weaken access to asylum, downgrade people’s rights & increase the risk of refoulement & arbitrary detention in countries outside the EU.

50+ NGOs call on EU to reject attempts to weaken protections further.
