I Introduction
In the spring of 2015 the District Court of The Hague issued a ruling that had a tremendous impact across the globe.Footnote 1 In the case of Urgenda ea v the State of the Netherlands the Court issued an injunction against the Dutch government to reduce the emission of greenhouse gases (GHGs) before 2020 by 25% compared to 1990, whilst the government policy aimed at a reduction of (not more than) 17%.Footnote 2 Perhaps even more surprising than the decision – taken only six months before the UN Conference on climate change in Paris in December 2015 – was the reasoning of the Court. After allowing standing to Urgenda as plaintiff, the Court reasoned its way through the key concepts of tort law to motivate its decision that the State had violated its duty of care towards its citizens. In doing so, the Court used international and European obligations to construct wrongfulness under national tort law on the one hand, and displayed all available scientific knowledge to substantiate that wrongfulness on the other. In fact, the Court attributed responsibility for a sustainable development of the atmosphere to the Dutch government, and did this on the demand of a rather haphazard organization of worried citizens. Therefore the Urgenda ruling raises questions with regard to the role of the civil court as risk regulator, especially with regard to the legitimacy of this role.
The Urgenda ruling raised many reactions, of course, some of them critical.Footnote 3 Is this ruling not a clear violation of the principle of the separation of powers? Is the Court not misusing tort law to trespass the domain of the politically legitimised legislator? If the judiciary does not hesitate to correct politics on a sensitive topic like climate change, what will be next? Other reactions were more favourable, however, praising the Court for its courage to step in where politics left off.Footnote 4 Is this not a clear signal that politics is losing control on the emission of GHGs, since they are too busy fighting about the question of who is to pay for it? Did the Court not understand the signs of the times correctly, as the Warren Court did when it called a halt to segregation in Brown v Board of Education?Footnote 5 Although there were also more neutral commentsFootnote 6 , the ruling of the Court divides commentators. What is lacking most of the time, however, is a critical reflection on the principles to decide who is right and who is wrong in this debate. What (kinds of) principles are involved? How are they to be interpreted? What effect do these interpretations have in the issue of the legitimacy of this ruling? And what do they imply for the role of the civil court as risk regulator more generally? Is the civil court just there to apply a pre-established scheme by the legislator? Is the scope of its decisions restricted to restore corrective justice between two litigants? Or may its decisions have a wider scope, displaying a more ambitious role? And if so, what limits are to be taken into account here?
In researching these questions, I will try to construct some building blocks of the normative/theoretical framework that provides the background of my answers. This means that I have a smaller and a bigger project on my hands. The smaller one is the question into the legitimacy of the Urgenda ruling. The bigger one concerns the issue of the legitimacy of risk regulation by the civil court, or perhaps of civil adjudication as such. Which principles determine the legitimacy of the civil court’s participation, especially in the domain or societal risk regulation? I will put my charts right on the table. My claim will be that these principles concern (amongst many other things) the position of the court, the tools of the court, and the attitude of the court. In other words, they have their source in constitutional law, in civil (procedural) law, and in professional ethics respectively.Footnote 7 Therefore I will first address the constitutional principles (Section II), then the civil (procedural) law principles (Section III), and finally the moral attitudes with which they are both interpreted (Section IV).
In doing so my presupposition is that there is an element of choice in judging, which may be used for strategic reasons.Footnote 8 This implies that within the normative/theoretical framework developed here, different choices may be legitimate, even irreconcilable ones, as long as they stay within the framework. This seems to be in line with the common legal sense that different judicial decisions in one case may be correct, and are in fact the subject of continuous debate, as long as they do not fall outside the scope of legal reason. One of my conclusions will be that the Urgenda ruling is legitimate in this sense, since it falls within the scope of our framework (Section V). It is my contention that this framework may be used in other cases as well, and as such contributes to the bigger project referred to above.
II Constitutional principles
The argument most often used against the Urgenda ruling is that it violates the principle of the separation of powers (“Trias Politica”). The central idea is, of course, that the doctrine of the separation of powers specifies a certain division of labour between politics and the judiciary, and that the Court in the Urgenda ruling trespasses the political domain.Footnote 9 The Court reviews such a highly sensitive topic for governmental policy as the emission of GHGs, and even gives an injunction to the government to adapt its democratically established policy. In doing this, the Court makes decisions that are essentially political by nature and therefore ought to be taken by the legislator or the government, but in any case not by the judiciary. One of the main arguments of the State was therefore that the debate on the emission of GHGs belongs in Parliament, not in a court of law.
For this reason, the Court explicitly addresses the argument, but refutes it.Footnote 10 The Court reminds us that under Dutch constitutional law there is no strict separation of powers, but a balance of powers. With regard to lawmaking the role of the judiciary is a subordinate one. Although it is generally recognised that the judiciary is legitimised to interpret statutes and even to fill the gaps in the legal system, this still restricts its role to that of a substitute for the legislator. When it comes to the grand design of society and the formulation of policy, the Court has to show restraint. With regard to legal protection, however, the judiciary is in the lead. The government is the defendant and its conduct is subject to judicial review. Since this system of legal protection is guaranteed by law, it is democratically legitimised. Urgenda’s claims do not stretch outside the judicial domain since they do not ask for an order to legislate (which is prohibited under Dutch case law).Footnote 11 Furthermore, the requested injunction may be executed by different means, which is left to the discretion of the State. For these reasons, the Court itself sees no violation of any constitutional principle or rule if it orders the State to adjust its climate policy.
Although this is a subtle enough reasoning, it clearly has not convinced the critics. The core of their criticism still is (and will be) that the Court ought to have rejected the claims of Urgenda under the separation of powers doctrine. The discussion focuses largely on the independent position and the impartial role of the judiciary, especially in cases of legal protection against the government. An activist court in politically sensitive issues runs the risk of jeopardising its impartiality. There is a clear phrasing of this risk: “The extra man on the field: Hey! Wasn’t that the umpire?”Footnote 12 Of course, if the umpire becomes an extra player, this distorts the whole logic of impartial conflict resolution. From then onwards, it will no longer be a game of one against one, decided by a third party, but a game of two against one.Footnote 13 For a court wanting to execute its own legal policy there may be strong reasons to step in, especially in case of government failure. On the other hand, this temptation may – according to some: must – be tempered by institutional concerns about the legitimacy of the decision.Footnote 14
What strikes me in this debate is that the critics have overlooked an important change in the legal landscape, namely the development from a single- to a multilayered legal system. In the Urgenda case, the Court was not only confronted with national tort law, of course, but also with norms of international law, European law, and human rights law, to mention only the most important ones. What is more, these systems of norms are not separated ball-games anymore; they mutually influence one another and have to be interpreted into one coherent applicable legal framework. To continue on the metaphor of sports: “The extra field to play: Hey! Wasn’t that a separate game?” Less metaphorically, the Court sees itself confronted with norms of different legal systems, each with their own legal sources, institutions, norms, conditions of satisfaction, legal consequences, and binding force. Although most of the norms of transnational origin are not directly applicable under Dutch law, the Court argues that they may have “reflex effect” on the open norms of national tort law.Footnote 15 This means that they substantiate the open norms of national tort law and thus have an indirect but substantive and normative effect on the case at hand. As such, they do bind the government’s policy on the emission of GHGs, and it is for the Court to interpret and execute this amalgam of norms.Footnote 16
This change in the legal landscape does not just effect substantive law, it has wider implications for the principle of the separation of powers as well. In a multi-layered legal system like this one, the Court is not only engaging with the national government and parliament, but also with European courts, international courts, and other European and international institutions. There are many more players on the field now, each with their own mission and responsibilities. If we take the principle of the separation of powers seriously – not just referring to the relation between the national legislator and judiciary, but to the idea and value of checks and balances – we must extend its scope to these new players as well.Footnote 17 This extension of the principle of the separation of powers to the transnational stage has two, intertwined implications, for the dialogue between the institutions involved.Footnote 18 The first is that the transnational institutions involved share a common responsibility to establish and maintain a system of checks and balances between them. This common responsibility underlines the need for cooperation. The second implication, however, is that if this balance is disturbed for whatever reason, this may justify for each institution to operate strategically, in order to restore the balance.Footnote 19
At this point Eyal Benvenisti has claimed that this implies that national courts may be justified to engage in a counter-veiling coalition against new political powers at the transnational stage.Footnote 20 The Urgenda ruling provides a perfect illustration. The reason for the Court to correct the government’s policy on the emission of GHGs might very well have been that supranational decision-making was failing accross the board (apart from its judgment that the national reduction policy was substandard). If so, the decision of the Court does not violate the principle of the separation of powers, on the contrary, it is legitimised by this principle, now understood in its new extended application at the transnational stage. If all other institutions fail to develop a common policy that really addresses excessive global warming, the court is justified in its attempt to initiate a judicial counterveiling move that does just that. So I conclude, for now, that taking the transnational context into account sheds new light on the debate about the principle of the separation of powers, as well as on its role in the debate on the Urgenda ruling. Therefore the relevance of this change in the legal landscape is not restricted to the substantive law to be applied; it affects the constitutional position of the courts as such.
III Civil (procedural) law principles
I switch now from the Court’s position to its tools, and from the constitutional principles to the civil (procedural) law principles.Footnote 21 The starting point is that Urgenda displays both resemblances and differences to classical tort cases. The Urgenda case resembles classical tort cases in the sense that the Court reasons its way through familiar tort law concepts and standards. The Court applies the Learned Hand formula to establish the conclusion that the State has a duty of care towards its citizens to prevent a dangerous temperature rise of 2°C or more (compared to industrial times).Footnote 22 However, the government’s policy is to the best of our knowledge not sufficient to prevent this from happening, as the Court argued extensively. The conclusion of the Court is therefore that this policy is substandard, which constitutes a wrongful act that justifies an injunction to adjust the policy of the defendant on the emission of GHGs. This whole argument finds its home in the context of national tort law, the very substance of which is, of course, the attribution of risks.Footnote 23
However, Urgenda differs from classical tort cases in the sense that it is a class-action as well as a case of public interest litigation.Footnote 24 As class-action it started off as a claim of the Urgenda foundation and 886 individual plaintiffs, filed against the State of the Netherlands.Footnote 25 This combination already blurs the differentiation between individuals involved. A Dutch supporter of Urgenda may rightly identify herself with both the plaintiff and the defendant. Besides, the public interest at stake is phrased in the by-laws of Urgenda as “to stimulate and steer up transition-processes to a sustainable society, to start in the Netherlands”. For the definition of “sustainability”, Urgenda refers to the Bruntland-report, which reads: “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own ends.”Footnote 26 The public interest of a sustainable society encompasses both an international and an intergenerational dimension. The decision of the Court to grant access to Urgenda implies that it is allowed to represent citizens of this country, people abroad, as well as future generations. This unlimited representation is not just an accident, it is the “raison d’être” of Urgenda. This poses serious problems for the traditional patterns of legitimation in tort law.
As far as the legitimation of the Court’s decision is concerned, there are roughly two options, of which one justifies too little, and the other too much. If we stick to the deontic paradigm of tort law, our traditional legitimations stop short.Footnote 27 First, liability of the State cannot be justified by any compensatory scheme within the framework of the principle of corrective justice.Footnote 28 This can be illustrated by the Court’s rejection of the defence of the State that the contribution of the Netherlands in the worldwide emission of GHGs is too small to be significant (only 0.5%, which is not more than “a drop in the ocean”). Starting from the notion of proportional liability, the Court argues that the State cannot escape responsibility for its fair share by pointing to its small contribution. This fair share is substantiated by the commitments the Netherlands has undertaken on the transnational stage on the one hand, and the relative high proportion of emissions per capita of the Dutch population on the other. Whatever the merits of these standards, they are applications of the principle of distributive justice and a far cry from the regular patterns of legitimation of tort liability that stick to the principle of corrective justice.Footnote 29
Next, the liability of the State in Urgenda cannot be justified by the notion of satisfaction either. Generally we take the notion of satisfaction to include an element of recognition of the plaintiff’s suffering, mirrored in the penance the remedy inflicts upon the defendant. But whose suffering is recognised by this ruling, and who does penance? If everybody is a victim as well as a perpetrator of excessive GHG emissions, then no one in particular is. We simply lack an identifiable victim or perpetrator here – or a group of victims or perpetrators – except for those who favour or oppose a sustainable society. So again, the traditional legitimation patterns within the deontic paradigm of tort law stop short.
If we switch to the law and cconomics paradigm, however, we may find that it justifies too much. From this perspective, tort law is just another mechanism for deterrence and risk regulation, next to for example public law.Footnote 30 The decisions of a court in tort law may be assessed by its effects on the prevention of dangerous risks, or they may be judged by their consequences for the distribution of the benefits and burdens of risk-causing behavior. In this view, tort law is a focal point for the distribution of risks. Only when a redistribution is required – in case of disturbance – the principle of corrective justice comes in.Footnote 31 Although this may seem a plausible approach at first sight – especially from the standpoint of risk regulation – at closer inspection it turns out that it provides a distorted image of tort law adjudication. Of course, tort law adjudication may have implicit consequences for risk regulation, but it was not designed for that purpose.Footnote 32 Tort law was designed to right wrongs, not more or less. For that reason, the courts decide tort cases one by one, ex post facto, and on the ground of the concepts and doctrines of tort law. From the external point of view of the law and economics scholar, the court’s decisions may be justified by their deterrent effects, their consequences for rational risk regulation, or their contribution to a fair distribution of the burdens of precaution. From the internal point of view of the court itself, however, these legitimations are out of sight. They are not in the court’s toolkit and therefore not available as patterns of legal reasoning. In that sense, they legitimise too much, aiming at goals far out of reach for a regular court.Footnote 33
I hope this is sufficient to justify the conclusion that the available paradigms of tort law leave us empty handed. Of course, one could seek refuge in an alternative paradigm that focuses on the loss-spreading effects of tort law instead of its loss-shifting effects, and that assesses the distributive effects from some conception of social justice. But then the question is which conception of social justice, and on what grounds? This move would only shift our problem to the legitimation of the right theory of social justice, and would therefore still leave us empty handed. There are a few caveats though. First, this is not to say, of course, that tort law lacks legitimation, even from an internal point of view.Footnote 34 The development of tort law – and private law in general – displays the influence of both the principle of corrective and of distributive justice.Footnote 35 For this reason, all kinds of mixed theories have emerged, stressing the interplay between both founding principles.Footnote 36 The question for research is then what their respective jobs are, and how they both influence the regulation of risks in tort law.Footnote 37 In this context, we are warned, though, of the principle of distributive justice. Like a cuckoo in the nest, the principle of distributive justice has the tendency to dominate the deliberation process, squeezing out other considerations.Footnote 38 I will not elaborate on this here, however, since it is beside our project.Footnote 39
Next, if the paradigms of tort law leave us empty handed, this does not mean that no legitimations are available. If focusing on tort law turns out to be a dead-end street, we may have to look elsewhere. In my view, the key is to be found on the more general level of the view one holds on the role of civil courts in the political system.Footnote 40 For clarity we may distinguish two opposing paradigms here, which have been phrased the “problem-solving conception” and the “public life conception” of adjudication respectively.Footnote 41 In the problem-solving conception the civil court is there to litigate between opposing parties, roughly in the same manner an arbitration committee would do the job. This perspective on civil adjudication is dominant in neo-liberal policy-making, comparing adjudication with other mechanisms for conflict-resolution. In the public life conception, however, civil adjudication is claimed to have added value for society. In litigating conflicts civil courts develop new norms, enforce established ones, review public policies, and thus maintain the rule of law. Civil adjudication therefore has an inherently public dimension, which is lacking in the problem-solving conception.Footnote 42 In fact civil adjudication is part of the way a political community governs itself, and thus of the political decision-making process (where “political” is used in the broad sense of self-governance). Of course there are different responsibilities here. The grand design of society and the formation of policy belong to the political domain, but the review and even the correction of policy in the light of established rights and interests is a judicial responsibility.Footnote 43
The legitimation of the Urgenda ruling is to be found in this public life conception of civil adjudication. In this case the Court was not just litigating between opposing parties. The Court clearly pretended to offer legal protection to citizens against a government that infringed their right to protection against a dangerous temperature rise occurring. As such, the Court placed itself in a position to review the government’s policy on the emission of GHGs. Amongst many other things, tort law is an instrument for legal protection. So this is a legitimate use of tort law by a court that keeps an open eye for the limits of its reviewing role. It is important to note that there is a small but decisive difference between the design of a distribution scheme with regard to the burdens of precaution, and the review of such a scheme. The first is the prerogative of the government, the last is a judicial responsibility. Of course, the Court’s own conceptions of distributive justice may creep in its deliberations, as we have seen in its rejection of the State’s defence that it is only responsible for a small proportion of the worldwide emission of GHGs. This is just another example of the cuckoo effects of the principle of distributive justice. But as long as these conceptions back up the reviewing role of the Court, their application is legitimised by the public role of the Court as part of the political decision-making process.
IV Moral attitudes
Finally, the constitutional and civil (procedural) law principles involved are to be interpreted in the light of the moral attitudes of the court. In any plausible account the legitimation of principles, rules, cases and other linguistic standards, ends in non-linguistic practices, customs, or forms of life.Footnote 44 It would exceed the purpose of this article, however, to go into depths in the form and substance of what might be called a “judicial form of life”, but one fragment needs to be mentioned. I am referring to the notion that courts and judges adjudicate with restraint or in an activist manner.Footnote 45 Judicial restraint is commonly defended on constitutional grounds (referring to the constitutional position of the judiciary) and on methodological grounds (concerning the craft of judging).Footnote 46 Judicial activism, on the other hand, is often justified by a selected choice of examples, which display a positive impact of judicial intervention on societal problems.Footnote 47 For some writers the choice between judicial restraint and judicial activism is an ideological credo, expressing their personal professional beliefs.Footnote 48 For others, however, they may be used descriptively, referring to opposing but legitimate judicial philosophies.Footnote 49 I use the predicates “restraint” and “activist” also in this neutral meaning.Footnote 50 In this sense, they may be helpful in clarifying diverging interpretations of the (constitutional and civil (procedural) law) principles. The moral attitudes of judicial restraint and activism therefore, constitute the rock bottom underlying the diverging interpretations of the principles involved.
An activist interpretation of the constitutional principles is nowadays generally connected with a transnational outlook, in which the court sees its own position as part of a transnational system of checks and balances.Footnote 51 The Urgenda ruling provides an example. The reference to transnational sources and their “reflex effect” on the open norms of national tort law, reflect a broader outlook than the national arena. Of course, under Dutch constitutional law European law and directly applicable provisions of international treaties are part of national law. But the eagerness with which the Court in Urgenda has interpreted the open norms of national tort law in the light of transnational law (through the use of the notion of their “reflex effect”) exceeds far beyond what is considered necessary. This outlook may even extend outside the strictly legal domain, since judicial activism is not only motivated by the ideal of legal protection, but also by that of responsiveness.Footnote 52 At the time, national and transnational political institutions failed to reach agreement on the reduction of GHGs, which in itself legitimises the courts to step in. From this perspective, it may be perfectly justified for the court to intervene if politics fails. One may even conceive Urgenda as an attempt to start a counterveiling judicial force to tip the balance. In an activist interpretation of the constitutional principles this is not a violation of the principle of the separation of powers, but on the contrary, a validation of this principle, since it restores the balance.
As we have seen, the Court received criticism for this approach. In their objection that the Court trespasses the borderline between the judicial and the political domain, the critics focused mainly on the national arena.Footnote 53 From this perspective, the Court should have exerted more restraint, even in the face of political failure. This argument might be backed up by referring to the virtues of judicial restraint (“the art of silence”). Civil courts are there to litigate conflicts, case by case. They perform this task in a subordinate position vis-à-vis politics. Their primary responsibility is the application of the law, not the solution of societal problems, nor the pursuit of political ideals. For all these reasons, the Court was way out of line with Urgend, at least in this restrictive interpretation of the constitutional principles involved.
The moral attitude of the Court is relevant for its interpretation of the civil (procedural) law principles involved as well. An activist interpretation of these principles is generally connected with the role of the civil court as part of the political decision-making process (in the sense of the self-governance of society). Of course, there are limitations here. A court is not there to formulate policies, but it has the legal responsibility to review the government’s policy, if called upon. Again, Urgenda provides an example. The review of the government’s policy on the emission of GHGs requires highly political decisions with regard to the distribution of the burdens of precautionary measures. Although these decisions transcend the regular case-load of the Court, this need not withhold it. Its intervention is legitimised by its reviewing role and is therefore restricted to the correction of the policy under consideration, if this infringes individual rights.
The critics however, focus on a more restrictive interpretation of the principles involved. A civil court should restrict itself to conflict resolution; the rest is up to politics. In tort cases the court is there to right wrongs, nothing more or less. In classical tort cases the decision is legitimised by traditional patterns, such as a compensatory scheme on the ground of the principle of corrective justice, or perhaps the notion of the satisfaction of the plaintiff. Again, from this perspective Urgenda shows why one should exert restraint. The Court was engaged in highly political decisions, concerning the distribution of the burdens of precaution between different parts of the world and different nations. This exceeds the tools available to a civil court, both from a conceptual, regulatory, and legitimising point of view. The intervention of the Court in this case therefore cannot be justified in the restrictive interpretation of the civil (procedural) law principles involved.
In the end, the interpretation of both kinds of principles rests on a choice between an activist attitude and an attitude of restraint. Clearly, in Urgenda the Court has chosen for an activist attitude, both with regard to the interpretation of the constitutional principles and the civil (procedural) law principles involved. Of course, it could have chosen differently. The Court could have exerted restraint, sticking to a national outlook and to a traditional approach of tort law. That would have resulted in another decision and reasoning, perhaps more mainstream. Does this entail that the actual ruling lacks legitimation, that it falls outside the scope of legal reason? I wouldn’t think so: within an activist interpretation of the principles involved the decisions made are perfectly justified. Finally, the Court could have chosen for a purposeful regulation of risks as well, justified by its own assessment of the consequences, or its own standards of distributive justice. However, that would have led the Court outside the domain of tort law, with its distinctive concepts, principles, and legitimations.
V Conclusions
Our question was which principles determine the legitimacy of a judicial intervention in the domain of societal risk regulation. I have argued that the building blocks of a normative/theoretical framework for the assessment of the legitimacy of the participation by the judiciary in civil cases are provided by constitutional law, civil (procedural) law, and professional ethics. The legitimacy of participation of the civil courts is therefore determined by constitutional principles, civil (procedural) law principles, and moral attitudes. Of these determinants the moral attitudes are the most fundamental ones, although one may recognise the attitude displayed by the given interpretation of the principles involved.Footnote 54
With regard to the constitutional principles we have found that the principle of the separation of powers may be viewed in a national context (as is traditionally the case), or in a transnational context (as is relevant since the emergence of our multilayered legal system). When courts have an activist attitude they are generally more inclined to interpret this principle in its transnational context. This opens both coordinating and strategic perspectives for the court, engaging in judicial dialogues with other courts. As long as they use this discretion to maintain checks and balances, they are perfectly in line with the principle of the separation of powers. Courts that exert restraint, on the other hand, are inclined to stick to their subordinate role vis-à-vis the political institutions.
With regard to the civil (procedural) law principles we have found that the court may have a self-image as a civil litigator (the traditional view), or as part of the political decision-making process (as many courts do). When courts have an activist attitude, they are generally inclined to the last. For them, tort law may be (amongst many other things) an instrument to correct government’s policies if needed. This opens a perspective for the court to correct government’s policies with distributive implications, if they infringe individual rights. As long as the courts do not exceed their reviewing authority, they are perfectly in line with the principles involved. Courts that exert restraint, on the other hand, are inclined to stick to their self-image as civil litigator, as well as to the traditional conception of tort law in which legitimations like compensation and satisfaction dominate their decision-making.Footnote 55
It turns out that the choice between an activist and a restrictive interpretation of the principles involved, plays a key role. In general it limits the possibilities for a normative-theoretical framework to assess the legitimacy of judicial rulings. Although one may have a preference for one moral attitude over the other, it is generally recognised that they are both legitimate judicial philosophies.Footnote 56 A specific ruling that falls within the scope of one these moral attitudes – and its interpretations of the principles involved – may therefore be considered legitimate, although one may disagree with the decisions taken, or even consider them wrong.Footnote 57 The Urgenda ruling, for example, may be questioned by its opponents. But even if they are right that it is wrong, it does not fall outside the scope of legal reason, and is therefore legitimate.
