Introduction

Much has been written in praise of the Court of Justice’s role in promulgating legally binding obligations pertaining to judicial independence on the basis of Article 19(1) TEU. To ensure effective legal protection in the fields covered by Union law, Member States must ensure that all national courts which may rule on the interpretation or application of Union law meet the requirements of independence, impartiality and previous establishment by law.

But might there be a trap door built into the rather impressive stage that the Court has been constructing in recent years? I happen to think so. Simply stated, my concern is this – what happens when national courts try to interpret and apply the manifold legal principles flowing from the CJEU’s judicial independence case law and get things wrong?

The stakes have recently been raised by the CJEU’s confirmation in AW “T” that provisions of national law may need to be declared null and void as a matter of domestic law whenever they infringe EU judicial independence standards. This includes lower-instance courts being obliged to find decisions of hierarchically superior national courts to be null and void.

Thus, in the name of protecting the rule of law, one now faces the very real prospect of national courts (either in good or in bad faith) expunging measures from their domestic legal systems on the basis of an erroneous application of EU judicial independence standards.

The Risk of National Courts (incorrectly) Policing Judicial Independence

The recently decided Daka case offers a good illustration of the concerns at play here. The case concerned decisions taken by the President of a national court to re-assign judges from one chamber to another chamber of that court. Those re-assignment decisions were taken without the consent of the re-assigned judges, did not contain any reasons and did not seem to be open to judicial challenge. Furthermore, the appointment of the court President issuing the relevant decisions was itself incompatible with Article 19(1) TEU. These factors prompted a national court, composed of re-assigned judges, to refer questions on the compatibility of the above with Article 19(1) TEU. In response, the CJEU surprised commentators (here and here) by finding that the re-assignment decisions of the non-independent court President were compatible with judicial independence standards flowing from Article 19(1) TEU.

But what if, instead of seeking guidance from the CJEU, the national court in Daka had concluded, not unreasonably in my view, that the re-assignment decisions were contrary to EU standards of judicial independence? In light of the abovementioned development in AW “T.” , a national court in a position similar to that in Daka might plausibly conclude that that national measure must be declared null and void.

The problem, however, is that we know that in Daka itself such a finding would have been incorrect as a matter of EU law. And it is here, I submit, that a possible trap door becomes partially visible. The problem stems from the role that EU law requires national courts to play in defending judicial independence on the ground in the Member States. According to settled case law, “the guarantees of access to an independent and impartial tribunal previously established by law, and in particular those which determine what constitutes a tribunal and how it is composed, represent the cornerstone of the right to a fair trial. That right means that every court is obliged to check whether, as composed, it constitutes such a tribunal where a serious doubt arises on that point…such a check is an essential procedural requirement, compliance with which is a matter of public policy and must be verified of the court’s own motion,.” There is also an “inextricable link” between the requirement of access to a court or tribunal previously established by law and the guarantees of independence and impartiality of judges. Finally, the requirements of judicial independence flowing from Article 19(1) TEU are capable of direct effect and must, therefore, be dutifully applied by national courts. It follows that the main responsibility for ensuring compliance EU judicial independence standards lies with national courts, whether in relation to their own independence, or the independence of other courts.

Consider in this regard the recent judgment on whether Article 19(1) TEU precluded national rules on setting national judicial salaries. In that case, the CJEU set down several very detailed principles that must henceforth be considered when national authorities enact rules for setting national judicial salaries. These principles also form the basis of any subsequent judicial review. They are intended to be applied by national courts to national rules and practices. Accordingly, what would prevent a national judge from incorrectly applying those principles in a future case and deciding, as a result, that national rules on judicial salaries must be disapplied or even declared null and void? And what if that national judge erroneously finds a violation of Article 19(1) TEU in such a case, without ever having referred the matter to Luxembourg? Crucially, the wide-ranging scope of application of Article 19(1) TEU means that virtually all national laws and practices touching upon the organization of justice within the State could now suffer a similar fate. Thus, far greater disruption can be caused to national legal orders by a misapplication of EU judicial independence principles than in other areas of EU law. There is a world of difference between a national court erring in its application of EU law governing free movement of workers, say, and the same national court erring in its conclusion that the national supreme court lacks independence under Article 19(1) TEU standards, with all the consequences that that may now entail.

It is worth dwelling on what those consequences might now be for national justice systems. As Dougan points out, disapplication is an individual remedy provided by a national court to resolve a particular dispute. Once disapplied, the national law in question remains in existence and operation for all other purposes. In contrast, declaring a provision of national law to be null and void is a remedy of general effect and application. The relevant national provision, once nullified, ceases to exist, including for all other purposes. Thus, Dougan notes that nullity is “a very different, more robust and more far-reaching, response to incompatibility than disapplication.” The former “carries potentially widespread and more penetrating implications within and across the national legal system, for example as regards the impact on other relationships, and for other powers or actions, as well as for third parties.” Admittedly, the circumstances in which this novel remedy of nullity will be required as a matter of Union law remain uncertain. Nonetheless, there would appear to be more at stake for the functioning of national justice systems in a world where national courts may declare measures of national law to be null and void.

One must also be attentive to an altogether more worrying prospect that, I believe, is now in play here. In the name of EU judicial independence standards, lower-instance courts may utilise these developments to disapply or invalidate judgments of hierarchically superior national courts. It is perfectly foreseeable that, in some national legal orders, first instance courts and tribunals will be far more susceptible to having their independence eviscerated by the ruling executive than apex courts in that state. In circumstances where the constitutional or supreme court remains independent, but the lower courts do not, Article 19(1) TEU, coupled with the primacy principle, can now be used (in bad faith) by those captured lower courts to effectively neutralize decisions of their (independent) superior courts that would otherwise be binding upon them. Again, this can be done (disingenuously of course) in the name of upholding EU standards of independence.

Case C‑448/23, Commission v Poland (Polish Constitutional Tribunal) as a Possible Solution?

Now, the response here might be to fall back on the classic doctrines of EU law. The risk that national courts might err in their application of EU law has always been a structural feature of the EU legal system. There is nothing novel or surprising about EU law disrupting national judicial hierarchies. The above may be nothing more than an extension of Simmenthal to the rule of law context.  Moreover, tools such as Article 258 TFEU infringement proceedings and actions for state liability in damages serve to mitigate against these risks. It may also be possible to appeal against a judgment of a national court that allegedly misapplies Article 19(1) TEU, and for any appellate court to subsequently refer the matter to Luxembourg. However, all these corrective mechanisms have shortcomings that will be familiar to readers of this blog.

It is with this in mind that we can turn, in closing, to the recent CJEU judgment concerning the Polish Constitutional Tribunal. In my view, the judgment makes some important points about the role of national courts in ensuring compliance with Article 19 TEU standards, particularly in light of the problem I have identified above. The judgment hints in places (paras 102-120) at a solution to those problems that would centralize review in Luxembourg. The Court stresses that it has exclusive jurisdiction to give definitive and binding interpretations of EU law, including the requirements flowing from Article 19(1) TEU. Then, “in order to ensure the uniform application of EU law in all the Member States, as is required by Article 19(1) TEU, those requirements cannot depend on the interpretation of provisions of national law, or on the interpretation of provisions of EU law by a national court, which does not correspond to that of the Court (para 210, emphasis added). Thus, Article 267 TFEU sets up a system of judicial dialogue between national courts and the CJEU with the aim of securing the uniform interpretation of EU law.This is consequently the path that a national court must take when it has doubts as to the compatibility of national law with a provision of EU law requiring interpretation of the latter.” (para 212, emphasis added). Moreover, the obligation upon national courts to disapply any national rule that is inconsistent with Article 19 TEU arises “in the event of an established infringement of the second subparagraph of Article 19(1).” (para 115, emphasis added). Finally, the obligation to declare provisions of national law to be null and void is said to arise when “a national court or tribunal which has referred a question to the Court for a preliminary ruling” and subsequently “concludes that it is apparent from all the conditions and circumstances” that national law is incompatible with Article 19(1) TEU (para 120).

To my mind, these passages hint in the direction of finding that national courts must refer questions to Luxembourg whenever they harbour doubts as to the compatibility of national law with Article 19 TEU standards. How else would a national court ensure that it did not arrive at an interpretation of Article 19(1) TEU that does not correspond to that of the CJEU? How else might a national court determine that there had been an “established infringement” of Article 19(1) TEU before disapplying or nullifying the infringing provision of national law? Such a centralized solution, if confirmed, would essentially extend the Foto-Frost obligation to refer to Luxembourg questions of validity of national law when they arise in relation to Article 19(1) TEU. Such a solution would certainly mitigate against the risks of national courts causing major disruption to the organization of national justice systems whenever they incorrectly apply EU judicial independence standards. However, it would sit uncomfortably with the structure and wording of Article 267 TFEU, which affords lower-instance national courts with a discretion to refer (or not refer) questions of interpretation to Luxembourg. It would also sit uncomfortably with the obligation that direct effect and primacy place on all national courts to give full and immediate effect to Article 19(1) TEU standards by disapplying inconsistent provisions of national law. The alternative reading is that determinations of whether national rules and practices comply with Article 19(1) TEU standards remains a task that is primarily for national courts, most of whom are not obliged to refer such matters to Luxembourg.

Conclusion

The above is an attempt to articulate what I take to be a difficulty in the law of judicial independence as it currently stands. There is always a risk in such endeavours that one is identifying a problem that does not really exist. Perhaps there is no trap door built into the stage. It is also possible that the problem identified does exist, but is not as significant or difficult to solve as the above analysis might suggest. To be corrected on either of these points would be very helpful. It would mean that the stage rests on a firmer foundation than first feared. Alternatively, the above analysis might well be on to something. If that proves to be true, it will at least offer the consolation of being persistently troubled about the right sort of thing.
