I am very (very, very) proud to see my first book published! Such a pleasure to hold this in my hand as a hard-copy version. Feel free to let me know if you would like to discuss the role of discretion for migration decision-making in Europe! @groningeneulaw.bsky.social @rug.nl @uni-konstanz.de

This is our take regarding a currently pending case before the @eucourtofjustice.bsky.social concerning the Italy-Albania protocol and the possibility of externalisation of EU migration processing! /w the impeccable Eleonora Frasca for @verfassungsblog.de

So proud to see our work published, now also with page numbers! /w @detershenning.eupolicy.social.ap.brid.gy

Council of Europe countries adopt Chisinau declaration on ECHR and migration www.coe.int/en/web/porta...

My article examines detention in the current draft of the EU Return Regulation, which was supported by right-wing and far-right parties in the EU Parliament. The desperate attempt to increase return rates relies on deterrence rather than effectiveness and violates human rights.

Wonderful to see this comment on the Italy-Albania Protocol, together with Eleonora Frasca out with @verfassungsblog.de.

🇪🇺⚖️🇵🇱 Revenge is a dish best served cold (and after five years). Moments ago, CJEU, in the case Commission v. Poland, found that the Polish Constitutional Tribunal has not only violated EU law with its anti-EU rulings, but also was (is) not an independent court established properly by law. 1/

🧵 Let's break down the six security guarantees that European leaders have just committed to Ukraine as part of a future peace deal. Note: this is a commitment on paper for now.

🚨🚨Major #EU news: More than 80 percent of Europe’s companies will be freed from environmental reporting obligations after @europarl.europa.eu and @consilium.europa.eu reached a deal on a proposal to cut green rules on Monday. 🧵 www.politico.eu/article/eu-s...

This afternoon, we had a meeting of the Coalition of the Willing. I updated President Zelenskyy and leaders present on two key priorities - support for Ukraine and increasing European defence preparedness.

Today, the EU has shown that we can deliver. The Council reached a general approach on the safe third country concept and the first EU safe country of origin list. These are all measures that will help process claims more effectively and reduce pressure on asylum systems.

Unglaublich‼️Schon wieder reißt die EVP die Brandmauer ein – diesmal beim Waldschutz. Statt Kompromisse mit der Mitte zu suchen, peitscht sie ihre Maximalposition mit extrem Rechten durch‼️ Das schwächt das EU-Entwaldungsgesetz, bestraft vorbildliche Unternehmen & gefährdet bis zu 150.000 Hektar Wald.

Some positive elements included, such as a the principle of voluntary return. So-called 'return hubs' still in, raising significant legal problems.

Commission adopts stricter visa rules for Russian nationals

The @ec.europa.eu just adopted rules banning new multiple-entry visas for Russian nationals. From now on, only single-entry visas will be issued, with rare exceptions. The move aims to tighten security and pressure Moscow over its war in Ukraine but may be legally and politically problematic:

🇪🇺⚖️🇵🇱 On 2 December, CJEU will hear the case of European judicial associations challenging the Commission's assessment that Poland met the rule of law milestones for unlocking the RRF (recovery fund). Ahead of the hearing, the Court has asked the Polish government an extremely difficult question:

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 […] [Original post on eupolicy.social]

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 […] [Original post on eupolicy.social]

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 […] [Original post on eupolicy.social]

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 […] [Original post on eupolicy.social]

Russia launched more than 800 drones and missiles at Ukrainian targets overnight, with at least one strike damaging the government’s main building in Kyiv.

⚡️Update: At least 10 killed, 48 injured in Russian mass attack on Kyiv. The Russian attack also damaged a building of the EU mission to Ukraine, Foreign Minister Andrii Sybiha said on X. "This requires not only the EU’s, but worldwide condemnation," he added.

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’ @ecprtheloop.bsky.social 👇️

Poland is the latest to institute temporary border checks. What does that mean for the European Union's freedom of movement?

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. 🔗 www.amnesty.eu/news/eu-safe...

🇵🇱🇩🇪 There goes the other half of my fun during Poznań-Berlin trips. A predictable move, after the far-right established "citizen border patrols" on PL-DE border to stop German authorities from returning people to Poland.

The only welcome aspect of this is that it's finally some retort for Germans making the life of citizens of Zgorzelec, Słubice and Gubin harder, but it only comes now after Tusk's party dips in polls and the far right "take matters into their own hands".
