(CN) - Judges can't quietly sidestep EU law questions anymore. With Europe's top court ruling Tuesday, they must explain exactly why they chose not to send them to Luxembourg.
An immigration fight in the Netherlands ended up raising a bigger question about how EU law is handled in court. A Moroccan man living in Spain applied for a residence permit to join his wife and children in the Netherlands, who are Dutch nationals, but authorities turned him down, pointing to his existing residence permit in Spain.
He challenged that decision, arguing EU law gave him the right to stay with his family. When the case reached the Netherlands' highest administrative court, he asked judges to check with the Court of Justice of the European Union. They didn't. Instead, they shut the case down with a brief, standard explanation, teeing up the issue the EU court answered Tuesday.
The answer was no.
National courts can turn to Luxembourg when they need help interpreting EU rules, and for courts of last resort, that is usually required. They can step back only in narrow situations where the answer does not affect the case, has already been settled or is so clear there is no real doubt.
But they cannot skip the referral without explaining why.
As the judges put it, "that decision must, in all cases, comply with the requirement to state reasons ... namely to set out, specifically and concretely, the reasons why that exception applies."
That directly challenges how Dutch courts handle a large share of immigration cases. Under national law, they can dismiss appeals with summary reasoning, especially when arguments repeat or do not seriously challenge settled case law, a practice the referring court defended as efficient given heavy caseloads and the growing number of EU law questions.
The EU court was not persuaded.
It held that summary dismissals cannot satisfy the obligation to explain a refusal to refer unless they spell out, in concrete terms, why no referral is needed. The obligation also applies even if no formal request was made, as long as EU law is raised in the case.
Sacha Prechal, a professor of European law at Utrecht University and a former judge at the Court of Justice of the European Union between 2010 and 2024, said ahead of the ruling she did not expect judges to have to spell everything out in every case. In her view, it could still be clear from the procedure or context why no referral was made, calling it "a bit of a case-to-case approach."
Tuesday's judgment largely fits within that thinking, as it still allows for shorter, tailored explanations but makes clear that courts cannot leave their reasoning implicit and must spell out, in concrete terms, why they chose not to refer.
Jasper Krommendijk, professor of international and European law at Radboud University, said the ruling sharpens that line, stressing that the obligation applies "irrespective of whether or not that question is accompanied by an express request to make a reference for a preliminary ruling." In other words, it is enough that a party raises EU law for the duty to kick in. He added that the judgment is strikingly concise, given how heavily debated summary reasoning has been in the Netherlands for years, where courts have long relied on short, formula-style decisions.
That shift, in turn, is likely to be felt most by litigants. Guillermo Iniguez, a researcher in EU law at the University of Oxford, said the judgment is likely to increase transparency. Courts can no longer simply state that they decline to refer but must explain their reasoning, giving litigants a clearer understanding of why their case stays at the national level and, in some systems, potentially even allowing them to challenge that refusal on appeal.
Lorenzo Scarcella, a researcher at the University of Luxembourg, said the ruling ultimately tries to strike a balance, making sure people no longer have to guess why their case was not sent to Luxembourg while keeping the system workable, calling it a move that "balances the parties' right to an effective remedy and the public interest in the sound administration of justice."
He added that once EU law is in play, national judges must give reasons for not referring, even without a request, and showing that the answer is obvious can still be a demanding task.
From the applicant's side, lawyer Ellen Gelok, who represents the Moroccan man at the center of the case, called it "a wonderful ruling," emphasizing that it ties the obligation to give reasons directly to the EU treaty framework. She pointed in particular to the requirement that courts engage with both the facts and the legal issues, saying it effectively puts an end to standardized reasoning that does not reflect the specifics of a case.
The Dutch Ministry of Justice and Security said it has taken note of the judgment and is assessing its potential implications.
The case now returns to the Netherlands' highest administrative court, which must apply the ruling and decide again whether the Moroccan applicant can stay. The EU court's interpretation is final and cannot be appealed, so the judges will now have to rule on the residence permit, this time with a properly reasoned decision if they again choose not to send the case to Luxembourg.
