The Checkpoint That Wasn't

A court in Koblenz has ruled that Germany's border checks with Luxembourg are illegal under the Schengen Borders Code.[1] The ruling came in favor of a regular commuter who had been stopped multiple times between Schengen and Perl, arguing that the checks had become a predictable, recurring disruption rather than a genuine security measure.

The court found that Germany failed to meet the criteria required under the Schengen Agreement for implementing permanent border controls, at least for the period between 16 March and 15 September 2025. Those criteria include providing proper justification and informing neighbouring countries and European partners in sufficient detail. Germany, the court said, did neither.

This matters enormously for Luxembourg. Over 200'000 people cross the border daily from France, Belgium, and Germany to work in the Grand Duchy. That is nearly a third of the country's workforce. When Germany reintroduced border checks in September 2024 as part of a broader crackdown citing irregular migration, the impact was immediate: queues at the Moselle crossings, delayed buses, workers late for shifts, and a creeping sense that one of the EU's foundational promises, the free movement of people, was being quietly revoked.

The Schengen system allows member states to temporarily reintroduce border checks, but only under strict conditions: a genuine threat to public order or internal security, a time-limited duration, proper notification to the European Commission and neighbouring states, and a proportionality test. Germany's checks, initially announced for six months, have been repeatedly extended. The Koblenz court essentially said: you cannot call something temporary if you never stop doing it.

Germany retains the right to appeal. The German interior ministry has previously defended the checks as necessary for combating irregular migration and cross-border crime. But the ruling sets a significant precedent. If the decision stands, it undermines the legal basis for Germany's checks not just at the Luxembourg border, but potentially at all its internal Schengen frontiers with Poland, Czechia, Switzerland, Austria, France, the Netherlands, and Denmark.

For Luxembourg, the stakes are concrete. The country's economy depends on cross-border labour. Every minute spent at a checkpoint is a minute of productive work lost, a bus delayed, a delivery slowed. The Grand Duchy has long been one of the loudest voices in Brussels opposing the reintroduction of internal borders, and this ruling gives it legal ammunition.

The name of the town where the checks took place is almost too perfect for the story: Schengen, the Luxembourg village that gave the agreement its name. The place where European open borders were born now has a court confirming that those borders should still be open.
