The questions national courts ask, before Luxembourg answers them.

Preliminary references are EU law's early-warning system: every reference is a dispute a national judge could not resolve alone. EU Law Radar reports them as they are lodged — the questions quoted verbatim — and follows each case through to judgment.

Case C-318/25, Proschik – may a single judge be stopped from referring?

A judge in Erfurt hearing a GDPR claim against Meta alone wants to refer questions to Luxembourg. German procedure says a single judge who meets a question of principle must hand the case to the three-judge chamber — which may then decline to refer. The judge asks whether Article 267 tolerates a rule that lets a court's own colleagues stand between it and the Court.

Case C-496/23 P, Meta Platforms Ireland v Commission – how wide may a search term be?

In its Facebook investigations the Commission demanded every document held by named executives that matched broad search terms, over years, whatever it contained. The General Court found that 'necessary'. Meta's two appeals ask whether necessity is tested term by term or in the round, and what protects the personal information swept up. The Advocate General has proposed dismissing both.

Case C-523/25, Stichting Data Bescherming Nederland – who may sue Amazon for everyone?

A Dutch foundation is suing four Amazon companies for GDPR damages on behalf of everyone affected, without any of them having asked it to. The Rechtbank Rotterdam asks whether Article 80 of the GDPR — which lets a data subject 'mandate' a body to act — leaves room for the Dutch opt-out class action, and for the extra conditions Dutch law imposes on who may bring it.
