New chapter 📕 examining how the Court of Justice of the European Union decides not to decide cases. I argue that it does so through procedural control, narrow rulings, and related techniques. 🏛️🇪🇺 URL doi.org/10.1093/9780... (eds @luigilonardo.bsky.social, Alezini Loxa) #Europeanlaw #EUlaw #CJEU

Is there a political question doctrine in EU law? The CJEU long took no position. No more! It has now discovered and applied it. By me: 'From Search to Discovery of the Political Question Doctrine in EU law' in European Law Review, 2025, 50(6), pp. 761-774. URL: uk.westlaw.com/Document/I29...

Another EU law institute has arrived on Bluesky! 👋 Starting with a blog post you can really sink your teeth into... 🦇

Can the High Representative of the EU 🇪🇺 be in CJEU proceedings ⚖️ in their individual capacity (i.e., not as Commission VP, Head of the EEAS, other 'hats')? Evidently, yes, though with nuances as intervener, applicant, and defendant. My contribution in a new Festschrift: doi.org/10.1163/9789...

Is the Court of Justice of the European Union (CJEU) leaning too heavily on 'solidarity' in its rulings? I argue yes, and that is problematic as a matter of legal reasoning. The full article is in current issue of the Maastricht Journal (MJ): doi.org/10.1177/1023...

An excellent European Affairs Committee’s session on the legal aspects of UK-EU reset with @cbarnard.bsky.social, @grahambutler.bsky.social & Sir Richard Aikens is now available on-demand parliamentlive.tv/event/index/...

Deposit return schemes (on drinks containers) Are they still justified in the interests of the environment, as long claimed? They are an impediment to the EU's internal market in the food/drink sector. My new article (open access) in @recieljournal.bsky.social doi.org/10.1111/reel... #EUlaw

Liberty Media (commercial rights holder of Formula One, motorcar racing) wants to now acquire the commercial rights of MotoGP, motorcycle racing. The Commission is concerned this will lead to over-concentrated in the motorsport broadcasting market. Today's OJ: eur-lex.europa.eu/legal-conten...

European (non-EU) international administrative tribunals of international organisations. On the ECMWF Appeals Board and and the broader development of international administrative law. I have a new article in the Journal of International Dispute Settlement: doi.org/10.1093/jnli...

Just thought I would shamelessly repost this, given I originally posted it before the Bluesky gold rush: my and @grahambutler.bsky.social’s considered take on the extent of the Commission President’s power to sack members of the Commission.

Pleased to see this piece with @grahambutler.bsky.social published in the CML Rev. It draws interesting conclusions about the Commission President’s power to dismiss Commissioners, a power we think is more extensive than has been realised in existing literature. kluwerlawonline.com/journalartic...

Judgment by the Grand Chamber of the CJEU in Case C-551/21, Commission v Council (Gabon) today. Big win for the Commission. For almost all international agreements (ex. CFSP matters, it is 'it' that signs the treaty (para. 81), and not the Council. curia.europa.eu/juris/fiche....

There are good days. There are great days. And there are days when an article is accepted by the Common Market Law Review. @drjohncotter.bsky.social & @grahambutler.bsky.social, "The President of the European Commission and the Power to Request a Commissioner’s Resignation", CMLRev, Vol. 60 (2024).

Is a CFSP Common Position 'binding'? Denmark has changed it view. Today's Information newspaper: "Civil service misunderstood arms exports rules and misinformed parliament" (Embedsværket misforstod regler for våbeneksport og fejlinformerede Folketinget). www.information.dk/indland/2024...

Today, we celebrated the PhD defense of Christian Thorning, welcoming ‘highly learned opponents’ from @grahambutler.bsky.social Ulla Neergard and others. Congrats to the new doctor! Proposition no. 7 will definitely be worth considering for the next writing crisis!

Can an Member State national/Union citizen (not a third country national) have restrictive measures (sanctions) imposed on them? No clear answer yet. But today's judgment in Case T-313/22, Abramovich (paras. 163-164) appears to say yes: curia.europa.eu/juris/fiche....

Judgment of the General Court in Case T‑233/22, Islentyeva v Council today A dual Lux-Russian national holding a Lux private pilots license loses the case. But at the same time, clarifies that Lux is wrongly interpreting the CFSP sanctions (and she can still fly). curia.europa.eu/juris/fiche....

CJEU jurisdiction over human rights and EU foreign policy missions Analysis of a recent Advocate General's opinion, by Antje Kunst eulawanalysis.blogspot.com/2023/11/judi...

Opinion. Could the pending Court of Justice (Grand Chamber) judgments in: - KS and KD (Joined Cases C-29/22 P and C-44/22 P), - Neves 77 Solution (Case C-351/22), pave the way for EU accession to the ECHR? In my view: no. eulawlive.com/op-ed-jurisd...

Major CFSP case. Joined Cases C-29/22 P and C-44/22 P, KS and KD v Council and Others. Opinion of AG Ćapeta delivered this morning: The CJEU has jurisdiction to hear an action for damages brought by individuals within the CFSP. curia.europa.eu/juris/fiche.... #EUlaw #CJEU #CFSP
