I. Introduction
“[T]hree correcting words of the legislator and entire libraries are turned into maculature.”Footnote 1 Worse: three additional words and entire libraries will be filled again! Libraries have literally been filled since the introduction of the “principle of subsidiarity” into the European legal order.Footnote 2
Subsidiarity – the quality of being “subsidiary” – derives from subsidium. The Latin concept evolved in the military context. It represented an “assistance” or “aid” that stayed in the background. Figuratively, an entity is subsidiary where it provides a “subsidy” – an assistance of subordinate or secondary importance. In political philosophy, the principle of subsidiarity came to represent the idea “that a central authority should have a subsidiary function, performing only those tasks which cannot be performed effectively at a more immediate or local level”.Footnote 3 The principle was invoked in 1891 by the Catholic Church and received its celebrated form forty years later in the Encyclical Quadragesimo Anno.Footnote 4 When did the subsidiarity principle become a constitutional principle? The legal principle of subsidiarity emerged as a – contested – principle of German constitutional law.Footnote 5 And, it is through the medium of German constitutionalism that the principle of subsidiarity enters into the European legal order.Footnote 6
The Community principle of subsidiarity surfaces in 1975,Footnote 7 but would only find official expression in the text of the EC Treaty after the Single European Act (1986). The (then) newly inserted Article 130 r (4) EEC restricted Community environmental legislation to those actions whose objectives could “be attained better at Community level than at the level of the individual Member States”. The Treaty on European Union (1992) finally lifted the subsidiarity principle beyond its environmental confines. It became a general constitutional principle of the European Union. Article 5 (2) EC states: “In areas that do not fall within its exclusive competence, the Community shall take action, in accordance with the principle of subsidiarity, only if and in so far as the objectives of the proposed action cannot be sufficiently achieved by the Member States and can therefore, by reason of the scale or effects of the proposed action, be better achieved by the Community”. This formulation was ambiguous, and subsequent constitutional clarifications culminated in a special Protocol on the Application of the Principles of Subsidiarity and Proportionality added by the Amsterdam Treaty (1997).Footnote 8
Despite its literary presence, the principle of subsidiarity has remained a subsidiary principle of European constitutionalism. Why? The reason for its shadowy existence lies in the continued absence of clear conceptual contours. While the principle's ambiguity may have “save[d] Maastricht”,Footnote 9 its protean character defied concrete application as a new safeguard against European centralisation. If subsidiarity was everything to everyone, how should the Community institutions apply it? Furthermore, the assessment of subsidiarity has, in the past, been largely left to the Community legislator. This constitutional arrangement meant that subsidiarity was not taken very seriously by European constitutionalism.Footnote 10 In the light of this failure, various reforms were proposed to strengthen the subsidiarity principle as a “safeguard of federalism”.Footnote 11 Two reform options crystallised in the last decade. The first option concentrates on the procedural nature of the principle and attempts to reinforce subsidiarity as a political safeguard of federalism. The second option tries to “substantiate” the principle by strengthening subsidiarity as a judicial safeguard of federalism. In what ways would the Lisbon Treaty – if it enters into force – take up these proposals? Would the subsidiarity principle emerge strengthened? This is the question this (short) article will try to answer.
II. Strengthening the Political Safeguards of Federalism
The Amsterdam Protocol confirmed the “procedural” nature of the subsidiarity enquiry. Each institution was called upon to ensure that it complies with the principles of subsidiarity and proportionality.Footnote 12 “For any proposed Community legislation, the reasons on which it is based shall be stated with a view to justifying its compliance with the principles of subsidiarity and proportionality; the reasons for concluding that a Community objective can be better achieved by the Community must be substantiated by qualitative or, wherever possible, quantitative indicators.”Footnote 13 These procedural obligations are subsequently specified for each institution. The Commission must “justify the relevance of its proposals with regard to the principle of subsidiarity; whenever necessary, the explanatory memorandum accompanying a proposal will give details in this respect”.Footnote 14 The Council and the Parliament “shall, as an integral part of the overall examination of Commission proposals, consider their consistency with Article 5 of the Treaty”.Footnote 15 The Protocol was infused, through and through, with the philosophy of process federalism. Subsidiarity was – predominantly – a “political question”.Footnote 16
How could this procedural dimension be reinforced? The beloved proposal in the last decade has been to integrate national parliaments into the decision-making process of the European Union.Footnote 17 It was hoped that this idea would kill two birds with one stone. The procedural involvement of national parliaments promised to strengthen the federal and the democratic safeguards within Europe. This could be done in two ways. First, one could create a new European institution – a Senate – that would assemble national parliamentarians. Second, national parliaments as such could be integrated in the European legislative process.
In the past, the idea to create a European Senate as a second parliamentary chamber had high political support.Footnote 18 “At the root of all of the proposals for a second chamber there seems to lie a perception that there is a problem with the democratic legitimacy of the EU and its institutions.”Footnote 19 National parliaments were not directly involved in the European legislative process and they lacked control over national ministers voting in the Council. But is the creation of a European Senate the best constitutional medicine for the alleged democratic malaise? Would its involvement add a third source of democratic legitimacy to the European Union?Footnote 20 Serious doubts are in order. The Senate idea would simply not solve the practical problems which it seeks to address.Footnote 21 And from a theoretical point of view, it makes little sense. “[I]f the Council makes the law, and if Ministers in the Council represent their national parliaments, how can their parliaments be given a separate, valid legislative role”?Footnote 22 Why should there be two European institutions representing the national peoples? If the reason for this functional doubling is the increased independence of national governments from their national parliaments, why not strengthen the national safeguards of democracy? A European Senate would thus not add much democratic legitimacy to the European Union. The better view has therefore concentrated on its potential function as a political safeguard of federalism.Footnote 23. Yet, the idea of a European Senate was soon discarded on the road to reform.Footnote 24
The idea of involving national parliaments in the European legislative procedure was – not unsurprisingly – celebrated as the best solution by the European Convention.Footnote 25 “Such a mechanism would enable national parliaments to ensure the correct application of the principle of subsidiarity by the institutions taking part in the legislative process through a direct relationship with the Community institutions.”Footnote 26 This procedural vision of subsidiary would find its way into the (failed) Constitutional Treaty and now the (suspended) Lisbon Treaty. National Parliaments are to be accorded an active role in the functioning of the European Union “by seeing to it that the principle of subsidiary is respected in accordance with the procedures provided for in the Protocol on the application of the principles of subsidiarity and proportionality”.Footnote 27
What would the Lisbon Protocol change?Footnote 28 Did it offer the national parliaments a veto right (hard constitutional solution) or only a monitoring right (soft constitutional solution)? In addition to reaffirming the procedural hurdles of the Amsterdam Protocol,Footnote 29 the new Protocol will strengthen the political safeguards of federalism by involving the national parliaments as “watchdogs of subsidiarity”.Footnote 30 According to Article 6, each national parliament may, within eight weeks, produce a reasoned opinion stating why it considers that a European legislative draft does not comply with the principle of subsidiarity. Each national Parliament will thereby have two votes;Footnote 31 and where the negative votes amount to one third of all the votes allocated to the national parliaments, the European Union draft “must be reviewed”. This is called the “yellow card” mechanism, since the Union legislator “may decide to maintain, amend or withdraw the draft”.Footnote 32 The mechanism is strengthened in relation to legislative proposals under the co-decision procedure; albeit, here, only a majority of the votes allocated to the national parliaments will trigger it.Footnote 33 Under this “orange card” mechanism, the Commission's justification for maintaining the proposal as well as the reasoned opinions of the national parliaments will be submitted to the Union legislator. The latter will have to consider whether the proposal is compatible with the principle of subsidiarity. Where one of its chambers finds that the proposal violates the principle subsidiarity, the proposal is rejected.Footnote 34 While this arrangement makes it – slightly – easier for the European Parliament to reject a legislative proposal on subsidiarity grounds, it makes it – ironically – more difficult for the Council to block a proposal on the basis of subsidiarity than on the basis of a proposal's lack of substantive merit.Footnote 35
The Lisbon Protocol rejects the idea of a “red card” mechanism. The rejection of a hard procedural solution is bemoaned by some as the chosen procedural safeguards would “add very little” to the federal control of the Union legislator.Footnote 36 Others have – rightly – greeted the fact that the envisaged mechanism will leave the political decision on subsidiarity ultimately to the European legislator. “[T]o give national parliaments what would amount to a veto over proposals would be incompatible with the Commission's constitutionally protected independence”.Footnote 37 Indeed, “a veto power vested in national Parliaments would distort the proper distribution of power and responsibility in the EU's complex but remarkably successful system of transnational governance by conceding too much to State control.”Footnote 38 To have made national parliaments “co-legislators” in the making of European law would have aggravated the “political interweaving” of the European and the national level and thereby further deepened joint-decision traps.Footnote 39 Lisbon will thus continue to “proceduralise” subsidiarity without turning the principle into a hard and fatally efficient political safeguard of federalism. The soft constitutional solution will thereby channel national parliaments' scrutiny to where it can be most useful and effective: on their respective national governments.
III. Strengthening the Judicial Safeguards of Federalism
Past constitutional practice has concentrated on the procedural dimension of the subsidiarity principle. Has European constitutionalism thus rejected the judicial dimension and fully embraced the philosophy of “process federalism”? The Amsterdam Protocol had expressly acknowledged the possibility of judicial review in the Community legal order: “Compliance with the principle of subsidiarity shall be reviewed in accordance with the rules laid down by the Treaty”.Footnote 40 This had called on the European Court of Justice. Yet, the Court would only listen with one ear and leave the substantive subsidiarity analysis in the hands of the Community legislator.Footnote 41 However, the parallel application of political and judicial safeguards of federalism will be confirmed by the Lisbon Protocol.Footnote 42 But more than that: the European Convention had raised the argument that “judicial review carried out by the Court of Justice concerning compliance with the principle of subsidiarity could be reinforced”.Footnote 43
How could the judicial safeguards of federalism be reinforced? One idea has proposed an ex ante judicial review on subsidiarity grounds.Footnote 44 Modelled on the ex ante jurisdiction of the Court for international agreements,Footnote 45 this would allow the Court to subject a European bill to a subsidiarity review prior to its entry into force. A second proposal reified this idea by suggesting an independent new Court specialised in questions of competence and subsidiarity.Footnote 46 The Convention discarded both suggestions on the ground “that the introduction of a judicial review in the legislative phrase would be tantamount to the monitoring of subsidiarity losing its primarily political nature”.Footnote 47 But then, how could ex post judicial review of subsidiarity be reinforced? In order to answer this question, we need to take a step back and ask – again – what the subsidiarity principle is and what we want it to do.
The Court, and much of the academic literature,Footnote 48 makes a distinction between “whether” the Community should exercise its competence and “how” it does it. The former is conceptualised as subsidiarity the latter is viewed as proportionality. This distinction is misleading. Subsidiarity must be understood in terms of federal proportionality. Why? There are two reasons – one theoretical and one conceptual. Theoretically, a subsidiarity principle that concentrates on the “whether” of Community action operates within a philosophy of dual federalism. It is based on the either-or logic in which certain objectives should not involve the European Community or the Member States at all. By excluding the Community from the scene, subsidiarity sensu stricto protects a sphere in which the Member States can exclusively exercise their competences. And by insisting that certain objectives are “Community objectives” as they can only be achieved by the Community, the Court equally constructs a sphere in which only the European Union can operate.
But more importantly: on a conceptual level, it is impossible to reduce subsidiarity to “whether” the Community should exercise one of its competences. This follows from the constitutional structure of Article 5 EC, which distinguishes three constitutional principles: enumeration, subsidiarity, and proportionality. Where the Union enjoys a competence it is entitled to generally act within an area. The general “whether” of Union action is thus already answered for that policy area. The distinction between “competence” and “subsidiarity” – between Article 5(1) and 5(2) EC – will thus only make sense if the subsidiarity principle concentrates on the “whether” of the specific act at issue. But the “whether” and the “how” of the specific action are inherently tied together. The principle of subsidiarity will thus ask whether the European legislator has unnecessarily restricted national autonomy. A subsidiarity analysis that will not question the federal proportionality of a European law is bound to remain an empty formalism. Subsidiarity properly understood is federal proportionality.
What, then, is the difference between subsidiarity in Article 5(2) and proportionality in Article 5(3) EC? The answer is that both principles share a family resemblance.Footnote 49 The proportionality principle was historically designed to safeguard liberal values. Proportionality would protect private rights against excessive public interference.Footnote 50 The idea of excessive government interference can be extended into a federal context. But here it is not the individual autonomy of a person, but the collective autonomy of a people that is protected. In addition to its liberal dimension, the principle of proportionality may thus receive a federal dimension.Footnote 51 But this federal proportionality is the principle of subsidiarity; and to draw a line between proportionality and subsidiarity, the best solution would be to restrict the principle of proportionality in Article 5(3) EC to its liberal dimension. The constitutional triumvirate of Article 5 EC could thus be explained as follows: the enumeration principle will tell us whether the Community can act within a policy field. The subsidiarity principle would examine whether the European law disproportionally restricts national autonomy; and the principle of proportionality would, finally, tell us whether the European law unnecessarily interfered with liberal values.
But even if the Court comes to embrace subsidiarity as federal proportionality, what principles could assist it in reinforcing judicial review of subsidiarity? American federalism has never expressly recognised the existence of a principle of subsidiarity in theory or practice.Footnote 52 However, two indirect inspirations may still be distilled from the jurisprudence of the American Supreme Court. They are the “clear statement rule” and the “presumption against pre-emption”. The former is a judicial safeguard to maintain the political safeguards of federalism. Congress must state its intention to pre-empt State law clearly; for “to give the state-displacing weight of federal law to mere congressional ambiguity would evade the very procedure for lawmaking”.Footnote 53 The presumption against pre-emption goes slightly further than this.Footnote 54 It adds a substantive value in favour of State legislation and forms part of a “normative canon designed to protect federalism values”. “As such, the presumption against preemption is much like a number of other rules of construction derived from constitutional values, such as the rule of lenity in criminal law[.]”Footnote 55
These two American devices can, without much effort, be translated into European safeguards of federalism. The Court could insist on express pre-emption before concluding that a European law occupied the field. It could equally develop a judicial presumption against pre-emption in certain policy areas. Indeed, it has been argued that the subsidiarity principle as such should function as the textual foundation of a presumption in favour of national responsibility.Footnote 56 Yet, these two devices would only provide for a soft constitutional solution: the subsidiarity-inspired interpretation of European legislation. What about situations in which the European legislator spoke clearly and expressly field-pre-empted national legislators in violation of the subsidiarity principle? Then, the European Court would face a choice. It could conceive the judicial safeguards of federalism as mere “resistance norms”, that is “constitutional rules that make governmental action more difficult, but do not categorically exclude it”.Footnote 57 This is the present American solution.Footnote 58 Alternatively, it could – and should – outlaw disproportionate interferences into national legislative autonomy. However, this hard constitutional solution will imply that the Court abandons its manifest-error standard in relation to the question of subsidiarity. The Court would need to develop a stricter standard for the federal proportionality review. The fact that the latter may depart from the laxer standard for the liberal proportionality principle is no constitutional anomaly.Footnote 59 However, the hard constitutional solution would mean that the Court of Justice gets involved in fundamental political and social questions. But this is – after all – what constitutional courts do.
IV. Conclusion
The constitutionalisation of the principle of subsidiarity came at a time, when the European Community resolutely continued its path away from decisional intergovernmentalism. With the political safeguards of federalism in the Council loosened, a new constitutional principle was searched for to protect the Member States from the dangers of over-centralisation. As a constitutional principle, subsidiarity was designed to safeguard legislative space for the Member States by restricting European legislation to situations, where “the objectives of the proposed action cannot be sufficiently achieved by the Member States and can therefore, by reason of the scale or effects of the proposed action, be better achieved by the Community”.Footnote 60
In the past, the procedural dimension of subsidiarity has been the dominant perspective. Recent reform proposals have, consequently, aimed to strengthen this dimension by involving the national parliaments as watchdogs of subsidiarity. The Lisbon Protocol on the Application of the Principle of Subsidiary and Proportionality would create a “yellow” and an “orange” card mechanism. The rejection of the “red card” option is to be welcomed. The hard constitutional solution would not have offered a third source of legitimacy and the soft constitutional solution will channel the energy of national parliaments to where it primarily belongs: the control of their national governments. Lisbon would add an additional monitoring task, but this European task should only supplement their national responsibility.
The Lisbon arrangements may also call upon the Court to reinforce the judicial control of subsidiarity. The Court, too, would have a choice between a soft and a hard constitutional solution. The European Court could – like the American Supreme Court – essentially view the subsidiarity principle as a presumption against pre-emption. (While the Court has not pronounced on the issue, past judicial practice may be seen as a manifestation of its implicit acceptance.) However, presumptions can be overturned; and for that reason this article has argued in favour of a hard constitutional solution. In federal contexts, exclusively process-based theories of judicial review are misplaced as there are two democratic processes that claim authority.Footnote 61 A strengthened judicial commitment towards substantive subsidiarity will not mean revolutionary change. European constitutionalism has already made a commitment in that direction. Instead of leaving the federal philosophy to the political safeguards of federalism alone, the European legal order has already accepted substantive limits on the European legislator in the form of complementary competences.Footnote 62
