Europe's Highest Court Faces the Transparency Test It Long Demanded of Others

The revelation that more than 40% of judges and advocates general at the Court of Justice of the European Union hold private financial interests in sectors or companies affected by EU law would be notable on its own. Yet the shareholdings are only the visible part of a much larger institutional problem. The real issue is that Europe's highest court has built an ethics system almost entirely around trust in itself.

That distinction matters.

No evidence has emerged that the judges deliberately manipulated rulings to benefit their investments. But a supreme court does not depend only on actual impartiality. It depends on the public believing that impartiality exists. Once that confidence begins to erode, every controversial judgment risks attracting suspicion that would previously have been dismissed.

The CJEU's internal safeguards increasingly appear designed for another era. Judges evaluate their own potential conflicts. The allocation of cases remains largely opaque. Historical financial declarations are withheld from public scrutiny under the banner of judicial secrecy. External verification is virtually absent.

Independence, in other words, has gradually evolved into insulation.

That may once have seemed a reasonable trade-off. Courts require protection from political pressure, particularly those deciding disputes involving governments and powerful corporations. European integration itself relied on judges capable of acting without fear of retaliation from national capitals.

But independence is not the same as invisibility.

Modern governance expects institutions exercising immense authority to explain how conflicts are identified, monitored and resolved. Regulators disclose interests. Commissioners publish financial declarations. National governments increasingly face demanding transparency rules. The paradox is becoming difficult to ignore: the court responsible for interpreting many of those standards operates under weaker public accountability mechanisms than many of the bodies appearing before it.

The consequences extend well beyond ethics paperwork.

The CJEU sits at the centre of Europe's legal architecture. It settles disputes over competition policy, taxation, state aid, digital regulation, pharmaceutical markets and countless questions affecting billions of euros in economic activity. Every major judgment shapes investment decisions across the continent.

In such an environment, perceptions carry weight of their own.

Corporate litigants are unlikely to complain about predictable institutional structures. Member-state governments have little incentive to disrupt a system whose judges are nominated through national political processes and whose mandates remain renewable every six years. The existing model has powerful defenders precisely because it produces stability.

For the court itself, however, stability increasingly resembles stagnation.

One overlooked aspect of the debate concerns judicial mandates. Six-year renewable terms were originally intended to balance independence with accountability. Instead, they create an unusual dynamic. Judges inevitably know that another appointment depends, at least indirectly, on the governments that first nominated them.

That does not imply political influence over individual judgments. But institutional design rarely revolves around proven misconduct. It revolves around removing incentives that could reasonably invite doubt.

Other international courts have already moved in another direction, favouring longer non-renewable mandates specifically to reduce those pressures. Europe is now confronting the question of whether its own highest court has been left behind by governance standards it helped shape elsewhere.

Another shift is unfolding at the same time.

The European Ombudsman's decision to investigate the court's refusal to release historical financial declarations marks something larger than an administrative dispute. It signals that rule-of-law oversight within the European Union is beginning to look inward rather than exclusively outward.

For decades, Brussels evaluated judicial standards in member states, particularly where concerns arose over political interference. Today the debate has reached Luxembourg itself. The scrutiny no longer concerns governments resisting judicial independence. It concerns whether judicial independence has become so insulated that meaningful accountability is no longer possible.

That is an uncomfortable conversation for the European project.

The CJEU has accumulated enormous authority because member states accepted its legitimacy. Unlike elected institutions, courts possess neither armies nor budgets to enforce decisions. They depend on trust. Lose enough of it, and legal authority becomes progressively harder to sustain, even when judgments remain legally sound.

None of this suggests the court is facing a legitimacy crisis today.

But it does suggest that its current ethics architecture belongs to a previous generation - one built around assumptions that public confidence could simply be presumed rather than actively maintained.

The immediate controversy over judges' financial interests may eventually fade. Investigations conclude. Rules are clarified. New disclosure forms appear online. Institutions often survive such episodes with surprisingly little lasting damage.

The larger question will remain.

Europe must decide whether judicial independence should continue to be protected primarily through secrecy and internal discretion, or whether independence in the twenty-first century requires greater transparency precisely because courts exercise so much power.

Those are not opposing principles anymore.

The real policy failure exposed by this investigation is the assumption that they ever were.
