Abstract: This Insight briefly analyses ten most significant untenable assumptions underlying the Court of Justice’s ruling in Tjebbes (judgment of 12 March 2019, case C-221/17 [GC]), where the Court departed from earlier case-law by essentially tolerating the annulment of EU citizenship ex lege as a result of a non-renewal of a Member State passport, thus introducing direct discrimination between different groups of EU citizens and legitimizing the treatment of law-abiding EU citizens worse than known terrorists and ISIS wives. EU citizenship has thus lost its proverbial ‘fundamental status’, downgraded to outright irrelevance for no tenable reason.
Keywords: Tjebbes – dual nationality – expatriation – proportionality – EU federalism – EU citizenship.
In this Insight I explain how far the case of Tjebbes, where the Court of Justice has agreed in principle with ex lege stripping some EU citizens residing abroad of their EU citizenship status and EU democratic rights based solely on non-renewal of the passport, showcases the dangerous limits to the understanding of the concept of citizenship by the Grand Chamber of the Court of Justice. This Insight is a first reaction as opposed to a detailed case-note. The reader is advised to familiarize himself with the case before continuing with this text: I do not summarize what the Court has done. The case is so deeply problematic and most principally antagonistic to the logic of EU integration and meaningful EU citizenship that no summary will do justice to the intellectually vacant nature of the Court’s reasoning and approach. The Grand Chamber has to speak for itself. It is clear at this point that scholars and judges will no doubt need some time to come to terms with the huge negative implications of the case at hand. My goal in this Insight is to provide initial input for such reflection and outline merely the key flaws plaguing the reasoning of the Court as well as the underlying assumptions informing such reasoning.
The tension between EU citizenship and EU (internal market) law has been occupying the leading commentators for more than two decades, and has been summarized best by Prof. J.H.H. Weiler’s take on the Court’s early citizenship case-law: “L’aspetto problematico di questa giurisprudenza è che precisamente omette di compiere la transizione concettuale da una libera circolazione basata sul mercato ad una libertà basata sulla cittadinanza”. The uneasy story has reached its troublesome climax when the Grand Chamber rendered Tjebbes on March 12, 2019, making the possession of the status of EU citizenship potentially dependent, for a randomly selected group of citizens, on a non-hypothetical use of the rights it grants, thus rendering key case-law on the fundamental nature of the status and the crucial importance of defending its essence irrelevant. Both internal market law and EU citizenship law emerged as losers as a result.
Absent any necessity to do so, the Court nevertheless managed to open the EU law door to endorsing the downgrade of EU integration to irrelevance for a large number of individuals selected based on a combination of untenable logic denying citizenship’s abstract legal nature and the operation of foreign – Iranian, Canadian, and Swiss law in the context of depriving EU citizens themselves of any agency. The concept of dignity here is forgotten, since the holders of several citizenships are stigmatized in principle, made second class EU citizens for the sole reason of possessing a second nationality. Proportionality, which the Court calls for, is entirely deprived of the legally sound moral starting point.
It is old news that the logic of apartheid européen, to quote Balibar, is at the core of the EU integration project, where the whole idea of the EU as a common working-living space is only open to those in possession of the formal status of citizenship. Unlike in any other constitutional system around the world, in the EU the rights to reside, work, and not to be discriminated against in the whole territory of the Union are de facto and also de jure purely citizenship- as opposed to residence-based. Applying this same logic to dual national EU citizens is quite new, however.
To downgrade EU citizenship, while its significance is so absolutely all-encompassing, to an unfriendly subscription service under the pretext of respecting the separation of powers between the Member States and the EU is an unwelcome move pointing in the direction of the probable workability of Niamh Nic Shuibhne’s respect of the “federal bargain” thesis: the Court stays away from what is perceived as the national sphere of competences, again, potentially ignoring the language and the spirit of the Treaty (and adding more questions concerning the essential meaning of its earlier case-law). The fact that this has been done by the Court in an almost elegant nonchalant fashion makes it tragically comical, pace Coutts. Akin to Bulgakov’s Poligraph Poligraphovich, the main protagonist in The Heart of a Dog, caring to acquire a passport and a municipal housing registration while failing to grasp the limits of own humanity – the proletarian was a laboratory dog turned semi-human – the Court steers clear of the core ideas underlying the issue at hand, as I explain below outlining a selection of ten tragic misunderstandings earning this case a solid place in the hall of fame of the most intricately dubious tours de force of the highest Court in Europe.
A substantive issue of fundamental importance for the very essence of EU integration is misrepresented as a procedural discussion, where anything – especially the denial of legally-endorsed Europeanness, i.e. EU citizenship – is in principle allowed for no EU-law-compatible reasons. Proportionality is deployed to undermine the essence of the law: what the late Professor Tsakyrakis was weary of and what George Letsas has problematized with splendid precision: proportionality is meaningless without a defensible starting point, the minimal moral ground. Deaf to Vicky Jackson’s warning calls, the Court of Justice is not “proportionate about proportionality”. Tjebbes is thus in line with the dubious case-law showcased best by Opinion 2/13, where the core substantive constitutional question is ignored in favour of largely irrelevant procedural considerations, as Piet Eeckhout has brilliantly demonstrated. By sacrificing the very legal nature of its citizenship while safeguarding no substantive interest, EU law emerges, yet again, as lacking the rule of law, pushing the EU in the direction of taking up a role of a powerful actor of injustice: a possibility of which Gráinne de Búrca warned with sadness and clarity.
II. Annihilating the “fundamental” in the “fundamental legal status”
At issue was the fact that under the Dutch law the state does not remind you that you are about to be thrown out of the body of citizenry for no reason other than failure to submit non-self-evident paperwork. Somewhat similar to a well-known Slovenian example (see Kurić et al.), the Dutch State simply erases you in some cases. Of course, your Europeanness goes too, together with your Nederlanderschap. All those residing outside of the EU, who got several citizenships and have not renewed the passport for ten years or have not filled in an online form that they are interested in remaining Dutch, as it were, are potentially affected. ‘The right to have rights’, as well as the very membership of the national political community – pace Delvigne and all the high-brow talk of the EU’s democratic essence – is thus made dependent on some kind of a renewal, which is new (the law has been effective since 2013), counterintuitive (other Member States do not require anything similar), and, crucially, of which the State does not remind you: erasure happens by stealth. At the deepest level Tjebbes is direct denial of both the “sovereign citizen” logic, akin to the one formulated by the US Supreme Court in Afroyim v. Rusk (the branches of government are but custodians of popular sovereignty, so undoing citizens is not in their power) and the “citizenship as a human right” logic, as formulated, most recently, by Peter Spiro. In the words of Mr Justice Black, writing for the US Supreme Court, “In our country the people are sovereign and the Government cannot sever its relationship to the people by taking away their citizenship”. By contrast, EU citizens – thanks to Tjebbes – emerge as hostages at the whim of those in power.
What makes the whole story trickier is that an ordinary Dutch passport is valid precisely for 10 years (unlike the 5 year term, in force when the law in question entered into effect). Not renewing your passport ahead of expiration can thus result in the annulment of citizenship ex lege if you reside abroad and have some other citizenship. Ironically, renewing a passport or an ID card is not required to vote in the Netherlands, as expired documents are accepted for this purpose, which makes the loss of citizenship provision particularly incomprehensible. Indeed, not renewing a passport ahead of its expiration date is a particularly low-threshold test for losing nationality, making Dutch citizenship easier to lose even than the British – one of the global leaders on this count. In the context of the “hostile environment” for those disliked by the Government of Miss May, in Brexit UK it is enough that the Secretary of State is of the opinion that your being a citizen is not in the interests of the UK: we all heard abundantly about it in the recent cases of ISIS wives and other terrorists and active terror-sympathizers, now repentant, in some cases (e.g. Shamima Begum). The UK is not alone on this count of course, Cypriot citizenship, in another example, is also easy to lose: on Cyprus it is apparently enough in some cases to sell a house to be expatriated – another absurd rule with clear EU dimension likely to withstand EU scrutiny after Tjebbes. Compared with taking part in and actively supporting rape, pillage and killings by radical islamists, or selling a house you promised to keep, the Dutch standard seems to be a joke, which is not funny: fail to renew the passport before the expiration date and your citizenship evaporates. The Court of Justice has agreed in principle to allow the treatment of law-abiding EU citizens, which is worse than the treatment reserved for known terrorists.
If citizenship’s one right is the right to return home (and not to be deported from there) – in the case of EU citizenship, to return to the EU and remain in its territory, as per Ruiz Zambrano and its progeny – after Tjebbes we now know that this right alongside with all the other rights of importance abroad, such as voting in European elections and, where available, diplomatic protection, now can simply expire. That “Article 20 TFEU, read in the light of Articles 7 and 24 of the Charter of Fundamental Rights of the European Union, must be interpreted as not precluding legislation of a Member State such as that at issue in the main proceedings” is the new low of EU citizenship law, which will be difficult for the Court of Justice to beat in the future.
It is unquestionable, as the Court of Justice has underlined on numerous occasions, that EU citizenship’s acquisition and possession must have due regard of EU law even though it follows a ius tractum – derivative – logic with the Member States themselves obviously responsible for the grant, both of the national and of European citizenship to those who do not have another EU nationality. EU citizenship’s independent existence, scholarly calls for it notwithstanding, is currently impossible, which Tjebbes equally confirms. As per Micheletti, Rottmann and the very logic of EU federalism, as Daniel Sarmiento, among others, has explained in abundant detail and as has been discussed by the Court of Justice in depth in Rottmann, Member States’ competences in this field, although of fundamental importance, are not absolute. The crucial lesson of Rottmann is that EU citizenship is maturing into a possible trigger of the Court of Justice’s jurisdiction. Independent of the classical cross-border triggers, as reconfirmed in Tjebbes, those situations where EU citizenship status is potentially jeopardized by the issuing Member State fall, “by reason of [their] nature and [their] consequences, within the ambit of EU law”. Tjebbes does not formally contradict the established case law. It renders it substantively irrelevant. The far-reaching poisonous potential of Tjebbes is clear: EU citizenship made dependent on the renewal of a passport before its expiration is not a fundamental status of the nationals of the Member States. Tjebbes thus tacitly overturns all the case law, from Grzelczyk and Baumbast, to Rottmann and Ruiz Zambrano.
It is, in principle, OK, the Court of Justice tells us, to punish the non-renewal of a passport – a document that merely attests to the status of citizenship rather than granting or terminating the status, of course – with the annulment of citizenship as such. In failing to build on the spirit of the law as it stands and de facto erasing the long-cherished fundamental nature of the legal status at issue, Tjebbes boasts humongous negative potential in our populist times: only the ‘real’ Dutchmen will remain citizens. By definition instead of killing off EU citizenship as such, as the learned AG seemingly proposed in his Opinion marked by absolute deference to the Member States, the Court of Justice opted for vagueness poorly masking the absolute lack of principle. While the basic approaches outlined in Rottmann, Eman and Sevinger and Micheletti (an approach, which Sir Richard Plender and I have critically analysed elsewhere) seemingly hold, the Court, by not making a principled stance against an indefensible discriminatory policy of a Member State, turned all the possible arguments on their head. The disaster of losing EU citizenship based on an ex lege annulment, which comes without any warning and based on no wrong-doing or any citizenship-related developments in persons' lives, is presented as reasonable per se, since the form to retain citizenship is so easy to fill in to remain a citizen: the fact, which the AG has so clearly and misguidedly underlined. The absurdity of a presumption that someone is less Dutch and less European as a result of staying outside of the Union if – and only if – that person has another citizenship and does not fill in some obscure form (a real trap, with no reminder from the state) does not strike the Court as somewhat frivolous.
The Dutch submission concerning the lack of “genuine link” with the State of those who do not reside in the EU is recited uncritically. This is a radical departure from Eman and Sevinger, where the same Member State deployed the same logic with the only difference that instead of discriminating against those with no “genuine link” concerned the Dutch citizens residing in the Dutch Caribbean, as opposed to anywhere else in the world. This approach to equality was not accepted by the Court of Justice, which deployed the general principle of equality between the Dutch on Aruba and Melbourne and New York, to strike down the absurd “genuine link” logic. In Tjebbes, by contrast, the Court agrees that EU citizens with a Swiss citizenship residing abroad are radically different, from EU citizens without Swiss citizenship residing abroad, making the continuous enjoyment of the supranational status dependent on the lack of a foreign citizenship. EU citizenship, thus, is not at all idiot-proof for an idiotic reason: a Swiss-Dutch in Switzerland is apparently less European than a Dutch in Switzerland and the Court does not see any problem with this.
III. 10 select absurdities underlying the fail
Defiance to national rules, however absurd, is the key guiding star of the Grand Chamber in Tjebbes. Not a behaviour one would expect of a constitutional court acting as a truly insightful and responsible custodian of its legal system, if it leads to the denial of the only thing the EU legal order can offer a citizen: the status of citizenship on which all its rights and protections are based.
The judgment raises a number of (interrelated) burning questions/problematic assumptions about the nature of citizenship, which are of immediate importance including (but not limited to, given its all-round disastrous impact) the following ten:
1) Renewed ideological mischaracterization of citizenship as a “Special relationship of solidarity and good faith”: if EU citizens are those who are nationals of the Member States, it is clear that the status cannot depend, legally speaking, on any bonds of solidarity, since not feeling such a bond does not undo a nationality of a Member State, making the statement – an ideologically charged submission of the German government repeated from Rottmann – factually incorrect. What is at stake in Tjebbes is whether failing to renew a passport should undo one’s EU citizenship: the Court does not do the job of explaining how someone’s Swiss or Iranian citizenship undermines solidarity and good faith anywhere in the Union or outside of its territory. The answer why the Court does not go there is clear: because it is obvious that the possession of Swiss or Iranian nationality does not undermine any special legal relationship between the EU and its citizens. And if this is true, then it is precisely the task of the Court of Justice to defend EU citizens stripped of the status on a phony pretext, when the situation by its very nature and consequences falls within the scope of EU law. The law is such, once again, that citizenship is an abstract legal bond: those who believe in solidarity are citizens and those who do not, are citizens as well, meaning that solidarity is a purely ideological logically irrelevant reference.
2) Regrettable goal of the protection of “reciprocity of rights and duties”: while it could be tenable in the context of some Member State nationalities, for instance the Greek one, given that Greece boasts one of the largest per capita conscript militaries in the world, this 19th-century-inspired reciprocity cannot apply to EU citizenship, which knows no duties as per the text of Part II TFEU. In this context national claims to the existence of such reciprocities should be scrutinized critically: what if a Member State is simply willing to disenfranchise a particular group under this pretext (which has always been a classical deployment of citizenship duties since Dred Scott)? Even if the harmful legend is somehow convincing to some, it remains unclear how turning EU citizenship into a subscription operation based on the obligation of regular renewals for no reason and expirations without a warning would actually further such reciprocity? If the only duty that arises in Tjebbes is the duty to renew the passport, can it be wholeheartedly argued that this duty really be commensurable with the rights of EU (and national) citizenship? And what if there were no such duties (consider the case of mono-national Dutch EU citizens abroad) – would the Court of Justice then exclude such duty-less citizens from rights?
3) Regrettable connection between EU citizenship and residence. Why does residence in a particular place suddenly come to be of crucial significance for the enjoyment of the status of EU citizenship? None of the relevant provisions in the Treaties makes such a connection, rendering it dubious from the outset; presupposing that EU law frowns at its citizens’ travel and living a life around the world would be equally unacceptable outright: the Treaties nowhere state that the EU should be a cage, similar to North Korea or some of the Central Asian dictatorships. The Court has already pointed at the legal difficulty relating to such framing of EU citizenship in Eman and Sevinger. In that case the Court unconditionally confirmed that EU citizenship does not expire upon leaving the territory of the Union and continues as a fundamental legal status of the nationals of the Member States. In contrast, Tjebbes presents leaving the Union as potentially problematic in the light of the possession of the status of EU citizenship, which is a position as clearly untenable in its absurdity, as it is ultra vires, should the Treaties be taken seriously. The conceptual separation between the status of citizenship and the concept of residence unquestionably requires avoiding the confusion between the two. This is in particular due to the fact that many EU citizenship rights are not territorial in essence and can thus be enjoyed abroad too, including the right to benefit from the general principle of non-discrimination, as in Eman and Sevinger, which the Grand Chamber seems to have totally forgotten.
4) Regrettable exclusion of those residing abroad from body politic. Besides general non-discrimination where EU law applies, those residing abroad enjoy full membership of body politic – since, even in the Netherlands – voting from abroad is a citizenship right as well, thus extending to European Parliament elections. Tjebbes’s silence on this matter is very problematic, since the body politic is obviously not a fully territorial idea in EU law, while the deprivation of EU citizenship is now potentially territorialized. Following Delvigne the Court could be expected to be at least theoretically interested in a secret arbitrary disenfranchisement of a vaguely-defined group of EU citizens through ex lege expatriation.
5) Regrettable misrepresentation of the link with the State. Why is it that the legal link with the EU – EU citizenship – remains a legal bond only for those who do not have any other citizenship, turning into a check of residence for all the dual nationals? Should the genuine link imply some cultural baggage – like the humiliating knowledge of the answers to the dull Dutch naturalization tests – the possession of a different nationality cannot matter. Even more: EU languages and cultures obviously cannot die out on a 1h 20min KLM City Hopper flight from Schiphol to Switzerland with an open return date. Even a flight to Curaçao or Aruba would not suffice, as we know from Eman and Sevinger. It follows that the genuine link implied in Tjebbes is thus obviously not substantively linguistic or cultural. This said – and given that the body politic is not necessarily territorial, just as the rights of EU citizenship are not – the claim of the Dutch government that the genuine link connecting the Kingdom of the Netherlands with its citizens is in some way dependent on residence in a particular place in the world is not a logical conclusion. Tjebbes is an approving nod in the direction of an argument that does not stand, failing to capture the essence of citizenship: an obvious misrepresentation of facts.
6) Direct discrimination based on second nationality as a starting point emerges as a related problem. Why is direct discrimination between different groups of nationals of a particular Member State residing outside of the EU – the one outlawed in Eman and Sevinger – now allowed in principle? While Micheletti prohibited the undermining of EU rights of EU citizens who also have a third country nationality in the territory of the Union, the Court has reversed this in Tjebbes for those who are resident outside of EU territory, taking discrimination, rather than non-discrimination as the starting point, the soundness of which is dubious.
7) Regrettable misrepresentation of the geography of European integration is another puzzling point to mention. Why is the territory of rights confined to EU Treaty-based rights, as opposed to EU international agreements-based rights? Given that residence and work in Switzerland is one of the rights which EU citizens enjoy under the relevant bilateral agreement, to present Switzerland (or any EEA county with the sole exception of Liechtenstein) as radically different from an EU Member State on this count seems to amount to a misrepresentation of the legal-political reality on the ground, which is regrettable, given the depth of the level of integration achieved between Switzerland and the EU and, especially, the crucial role that free movement of persons has to play in this context.
8) Regrettable presumption of desirability of mono-nationality. EU law is mute on the number of nationalities EU citizens should be allowed to hold to remain connected to the Union. While the Member States could have different ideas on this matter – as they legitimately do – the Court of Justice could be reasonably expected to protect the interests of the Union by ensuring that one does not face a situation of being forced to renounce other nationalities which have been acquired in full compliance with the law in order not to be subjected to unjustifiable, unnecessary, and discriminatory EU citizenship annulments. Para. 46 of Tjebbes, where the Court lists examples of the circumstances to be taken into account in the context of the deployment of the proportionality text, thus sends a deeply problematic signal, especially given the growing toleration of the cumulation of nationalities all around the world and the solid nature of both human rights and sovereignty arguments in favour of such toleration as discussed above.
9) Absurd reliance on foreign law at hand in Tjebbes is contrary to the message of the autonomy of EU law that the Court seemed to be trying hard to articulate over decades, carefully building supranational law as a separate legal order. In this sense Tjebbes is contrary to a whole line of cases, from Micheletti and Kadi, to the Opinion 2/13. Even accepting the problematic assumption of desirability of mono-national populations, why is the continuous possession of EU citizenship made dependent on the law of other states extending (or not) and/or allowing to renounce (or not) their particular nationalities to the Dutchmen residing abroad? How is the autonomous supranational legal order come to be subjected, in essence, to the law of the third countries? And if possessing a non-renounceable nationality has to be tolerated and is thus obviously not really harmful, how could the subjection of a continued possession of EU citizenship to a renunciation requirement applied to a renounceable nationality be justified?
10) Misconceived references to international law is the tenth point I would like to highlight. The Court refers to the Convention on the Reduction of Statelessness (Arts 6 and 7 paras 3 to 6) and Convention on Nationality (Art. 7, para. 1, let. e) and para. 2), in a most problematic fashion. While allowing for the loss of nationality in the contexts covered by the Dutch law, these have nothing to say about EU citizenship. The Court simply pretends as if EU citizenship is merely a couple of additional rights on top of the nationality of the Member State, denying it an independent status, thus saying goodbye to the prevalent characterization of the status in the literature, rooted in the Opinion of AG Poiares Maduro in Rottmann, where EU citizenship has rightly been characterized as ‘autonomous’. Instead of critically engaging with the essential principled short-comings of the rules of international law invoked by the Member State in defence of its policy having potentially harmful effects for the project of European unity, the Court simply restates the dubious provisions, which are by definition – EU citizenship not being a nationality of a state – not designed to take EU citizenship into account. Tjebbes is thus in stark logical opposition to Kadi or Micheletti, representing a worrisome account of a truly uncritical reading of international law potentially at the expense of EU law’s autonomy: a particularly high price to pay for the constitutional system of EU law.
IV. The puzzling nature of Court of Justice’s proportionality: individual circumstances of what?
Unwilling to confront the unjustifiable assumptions behind the directly discriminatory subscription EU citizenship in principle, the Court opted for a humble questioning strictly confined to their effects. Para. 41 of the judgment is crucial in this regard. The Court stated that “the loss of the nationality of a Member State by operation of law would be inconsistent with the principle of proportionality if the relevant national rules did not permit at any time an individual examination of the consequences of that loss for the persons concerned from the point of view of EU law”. But against which benchmarks? That not renewing your passport one day before it expired annuls one’s mystical “genuine link” with the Netherlands? From Micheletti we know that genuine links are not a tolerated part of EU law, which is in conformity with the framing of citizenship in international law, as Peter Spiro, among numerous others, has shown. Moreover, assessing genuine links would not be acceptable, since this would deny EU citizenship its abstract legal nature. As Christian Joppke has outlined in detail, where citizenship is legalistic and procedural, the only link one might have with a state is precisely the official decision granting citizenship, since residing in a particular place or speaking a particular language could not be framed as enforceable duties of citizenship outside of atrocious totalitarian regimes.
The check of the personal circumstances in the context of proportionality assessment is thus bound to amount to looking at the reasons why someone who possesses other nationalities than the Dutch has not renewed the passport of the Netherlands before the document expired. While seemingly accommodating and forward looking – on this Coutts is right – at its core the reasoning of the Court is thus devoid of substance at its best, since the Court failed to reaffirm any of the acceptable substantive principles in the context of EU law against which such individual assessment could possibly take place, thus undermining the very idea of a meaningful engagement. The fact that only dual nationals are presumed to have lost their genuine link with the EU as a result of not renewing the passport immediately is not even mentioned, just as the abstract and legal nature of the link required, reinforcing the intellectually vacant rationalizing of the Dutch government at the expense of the idea of European unity and law. A reference to the Dutch democracy and the will of the law-giver would be misplaced as a counter-argument, since this is precisely the idea behind the rule of law that the deployment of sovereign power should not be arbitrary, or justified by flawed, obviously non-sense reasons. Should the EU indeed be based on the rule of law, it definitely owes its citizens effective protection against arbitrary overreach of their national governments, where EU law is at play. EU citizenship, particularly as understood following Rottmann, is precisely such a domain. The idea of undoing European citizenship by stealth and for no objectively sound reason should be questioned in substance by the supranational Court of Law in charge of nurturing and preserving the status.
That the Court of Justice sensed that this be the case cannot be doubted: para. 46, where it reaffirms discrimination between dual and single Member State nationals is the core element of the judgment. Among the “circumstances of the individual situation of the person concerned” outlined by the Court are “limitations when exercising […] right to move and reside freely within the territory of the Member States, including, depending on the circumstances, particular difficulties in continuing to travel to the Netherlands or to another Member State in order to retain genuine and regular links with members of his or her family, to pursue his or her professional activity or to undertake the necessary steps to pursue such activity. Also relevant are (i) the fact that the person concerned might not have been able to renounce the nationality of a third country […] and (ii) serious risk, to which the person concerned would be exposed, that his or her safety or freedom to come and go would substantially deteriorate because of the impossibility for that person to enjoy consular protection under Article 20(2)(c) TFEU in the territory of the third country in which that person resides”.
Besides hinting at substantive conditions to be met for the enjoyment of the very Arendtian right to have rights, i.e. the EU citizenship status, the Court states also that “[t]hose consequences cannot be hypothetical or merely a possibility”, thus disqualifying the abstract nature of the citizenship status. What is not abstract leads to the concrete, begging for a conclusion that following Tjebbes the neo-Mediaeval turn in EU citizenship law has received a renewed boost. Indeed, Tjebbes‘s para. 46 with the list drafted by the Court, which seems so logical at the first glance is thus absolutely irrelevant in essence. The very enjoyment of the legal status of EU citizenship is made dependent, for a heterogeneous minority group (10 percent of the population) of dual Dutch nationals, on the use of the rights the status brings. Consequently, even beyond the discriminatory essence of the rule, the Court denies in principle the abstract legal nature of a bond between the Union and its citizens. This move opposes the vector responsible for the emergence of the classical understanding of citizeship in modern law – an abstract status of equals – desribed so well by Keechang Kim in his Aliens in Mediaeval Law.
V. The untold story: dual EU citizenship
The negative effects of possessing a number of nationalities, rather than one, are well known and have been, in the case of EU nationalities, excellently documented by David de Groot as far as the enjoyment of EU citizenship rights is concerned. To hear that even the status of citizenship can be in jeopardy as a result of having a Moroccan grand-father or an Iranian background – as one of the applicants in Tjebbes – is something new however. To make matters worse, the Court of Justice is silent on the loss of EU nationalities, while the learned AG endorses this in principle on a number of occasions (e.g. para. 93 of the Opinion), where he speaks about the fact that the operation of the same law, which is at issue in Tjebbes to the citizens of several EU Member States simultaneously is not a problem. This approach, besides being deeply counterproductive from the point of view of EU values – it disregards both the human rights and the sovereign citizen logic – is short of shocking for two key reasons.
Firstly, it is based on the assumption that acquiring a second EU nationality is not worthy per se, thus undermining the very logic of the Union as a supranational constitutional system ensuring, through the unity in diversity, that the citizens benefit from the supranational law, their legal heritage, to refer to the classical van Gend en Loos directly, taking crucial decisions about where and how to live their lives in the context of the whole territory of the internal market: Member State nationalities thus give access to rights in the whole territory of the EU – not a particular Member State – forming an intricate web of “intercitizenships” as I have argued elsewhere. To imply that cumulation of Member State nationalities is somehow a hostile act on behalf of EU citizens, which should be frowned upon contradicts the very logic of integration and cannot, thus, be endorsed by the highest Court, even en passant, as if it does not matter. To treat dual nationality in the EU context in the same way as it is treated with Iran or Canada misses the special nature of the Union, ignoring what Allott called a move from “diplomacy” to “democracy” at the international plane.
Even worse, secondly, the endorsement of the loss of the original Member State nationality by EU citizens who make use of their free movement rights punishes those who chose to naturalize in a new Member State thus taking a decision to take full part in the political life of that Member State. Before the problem of disenfranchisement of EU citizens who use their free movement rights has not been solved and national elections are not within the realm of EU law – which might never happen of course – it is impossible to make a convincing argument, it seems, in favour of the toleration of the loss of the original nationality as a result of naturalizing elsewhere in the EU. Such toleration pushes EU citizens to make a choice between the original nationality and taking part in political life in the place where they reside. To make matters worse, EU citizens are presented with this choice for no defensible reason, which makes it unacceptable in principle.
VI. Conclusion: a shameful fail
The true essence of things tends to reveal itself at a certain point. Just as Poligraph Poligraphovich in The Heart of a Dog, then already in possession of a passport and a municipal housing registration, turned back into a stray dog towards the end of the novella, EU citizenship’s abstract legal nature will unquestionably survive the regrettable absurdity of Tjebbes. Awaiting common sense one can only restate that punishing those who fail to renew a passport worse than known terrorists, jihadists and ISIS wives, denying them the legal connection with the EU and the rights to be enjoyed in the internal market, while opening a possibility to weigh this punishment against the use of the rights they are precisely being deprived of for no reason at all and in the interest of no stated EU-related common good, in the context where such use cannot be hypothetical or merely a possibility is undoubtedly a moment significantly undermining the EU integration project. European citizens deserve better. Denying the abstract nature of citizenship, directly discriminatory and stripping dual nationals of dignity as a starting assumption, Tjebbes is without any doubt among the high points of intellectual shame.

 To be fair, it is necessary to point out that the Court of Justice has already indicated, in its case law on ethnic minorities in the context of the internal market, that EU law will not apply to them as long as the Member State deploys identity reasoning, as became clear from the judgment of 12 May 2011, case C-391/09, Malgožata Runevič-Vardyn.

 This is of course true of the Netherlands itself, where to lose nationality for fighting for ISIS is more difficult than for not renewing a passport. The Dutch Council of State (Raad van State) on April 17 2019 has rightly annulled the expatriation of returning Dutch-Moroccan Islamist fighters, who deserved full due process of law (Uitspraak 201806107/1/V6, available at www.rechtspraak.nl): a review, to which a Dutch-Swiss, a Dutch-Canadian, and a Dutch-Iranian in Tjebbes were not entitled, since the facts were clear: while someone can make an argument that he did not fight for the Islamic State or other radical islamists, just training with Jabhat al-Nusra on an active vacation, for instance, determining whether one's passport has expired or not leaves less room for an argument. While an obvious way to go would be to ban expatriations, the Dutch Kingdom prefers an Islamist terrorist returning from a Syrian vacation to a Dutch-Swiss housewive as a citizen and as a voter and we now know that there is essentially no problem with such preference under EU law.

 Crucially, niether the Court, nor the Advocate General seem to be interested in any connection between the EU citizen and the Union, what AG Poiares Maduro suggested, for instance, in Nerkowska. Where the approaches to connecting citizenship and territoriality differ between the Member States to a great degree, non-discrimination among EU citizens would seemingly require not allowing radically different EU citizenship deprivation rules to apply to EU citizens solely based on their nationality. After all, nationality discrimination is prohibited within the scope of EU law and Part II TFEU obviously qualifies. To push this firther, one can quote Miguel Poiares Maduro: “Citizenship of the Union must encourage Member States to no longer conceive of the legitimate link of integration only within the narrow bonds of the national community, but also within the wider context of the society of peoples of the Union” (Opinion of AG Poiares Maduro deliveded on 28 February 2008, case C-499/06, Nerkowska, para. 23, emphasis added). As long as the majority of the Member States does not view their peoples as purely terriorial entities, EU law has to scrutinise such views half-heartedly proposed by the Netherlands in connection to its dual nationals very critically.

 The Grand Chamber, quite astonishingly, seems to be on the same page with AG Mengozzi on this issue, as well as some Italian doctrine. Giuseppe Tesauro's textbook, to give one example, had this to say about EU citizenship ten years ago: “non esiste, né potrebbe allo stato ippotizzarsi, una nozione communitaria di cittadinanza, sì che le norme che ne prescrivono il possesso come presupposto soggettivo per la loro applicazione in realtà rinviano alla legge nazionale dello Stato la cui cittadinanza viene posta a fondamento del diritto invocato” (G. Tesauro, Diritto comunitario, Padova: CEDAM, 2008, p. 480). Tjebbes is in full agreement with this statement.
