THE STRUCTURE OF THE NEW EUROPEAN PRIVATE LAW Martijn W. Hesselink** I B 1 1 Introduction For more than ten years there has been a debate going on in Europe on the future of European private law, and especially on the desirability and feasibility of a European Civil Code. This debate has recently gained special focus when the European Commission placed the need for a European Code of Contracts on the political agenda. 1 Assuming that at least part of private law could and should be common in the future2 , the question arises what structure this future common European private law should have. For most participants in the debate the default model for such a structure would be a European civil code3 . In this paper I address the question whether a classical code in the sense of the French Code civil of 1804, the German Bürgerliches Gesetzbuch of 1900 or indeed the Dutch Burgerlijk Wetboek of 1992 would be the most appropriate form for the new European private law. I will discuss eight aspects of the structure of European private law which cast some doubt on the desirability today of a civil code (or a code of contracts) in the classical sense. Some of these considerations are very practical, some others are more theoretical. In my paper I will pay special attention to Dutch law since this is meant to be a Dutch national report. 2 A Classical Civil Code The two main characteristics of a classical civil code are its (presumably) comprehensive and coherent character4 . Comprehensive in the sense that, as a result of abstraction, it deals in principle with all matters of private law (as opposed to public law), not in the sense of exclusivity: the legislator (or the courts) may come up with specific rules outside the code (e.g. in separate statutes). The code is presumed to be coherent in the sense that there is no contradiction between the rules contained in it, that each rule has one true meaning, and that it provides only one right answer ** Martijn W. Hesselink is Professor of Private Law and the Director of the Amsterdam Institute for Private Law (AIP) at the Universiteit van Amsterdam, the Netherlands. 1. Communication from the Commission to the Council and the European Parliament, COM(2001) 398 final (11.07.2001), No. 52. 2. I have addressed this question elsewhere. See my The Politics of European Contract Law: Who Has an Interest in What Kind of Contract Law for Europe? (Paper presented at the conference entitled Communication from the Commission on European Contract Law organised by the Society of European Contract Law on November, 30th and December, 1st, 2001 in Leuven, Belgium; the contributions will be published in 2002 by Stephan Grundmann (ed.)). In brief, my position is that it may be worthwhile to substitute national private law by European private law where the latter is better in substance. For me, that means, among other things, that it should be sufficiently social. 3. See e.g. ARTHUR HARTKAMP, MARTIJN HESSELINK, EWOUD HONDIUS, CARLA JOUSTRA, EDGAR DU PERRON, Towards a European civil code, 2nd ed., Nijmegen and The Hague/London/Boston 1998. 4.

to each legal question. Other characteristics of a classical code include its systemat character and its use of abstract rules and concepts. The new Dutch civil code of 1992 has the characteristics of a classical civil code The Private/Public divide The assumption that a civil code deals with all matters of private law and is pplicable to all conflicts between private parties is based on anotherassumption,ie that it is possible(and indeed useful)to distinguish between private hw and public law. Private aw is usually defined as the aw which govems relationships between citizens as opposed to public law, which is the law which deals with the relationships between citizens and the state or among state institutions. However, this clear-cut distinction does give rise to some doubt. Not only as a result of the development of dm inistrative law and, especally, of functional fields of the law which do not seem to fit in very well with this distinction; there is also a more fundamental critique First, in many countries the cases where the state acts asa private problematic. Classical examples include the case where a municipality buys new office equipment. In many countries private law(the civil code)applies directly or by way of analogy to such cases. However, if a European Civil Code were to be enacted should that code then also apply to(some)national (and European) public authorities? Moreover, in some countries national administrative law and private law are increasingly intertwined. For example, the recent Dutch Algemene Wet Bestuursrecht(1994), which codifies the general part of administrative law contains many structural and conceptual aspects which resemble the general part of private law(patrimonial law) conta ined in Books 3, 5, and 6 of the civil code which were enacted in 1992. With the enactment of a European Civil Code this strong link between national private law and national administrative law would be broken Unless, of course, national adm inistrative law was to beadapted to the new European Civil Code. This would mean, however, thatadministrative law in Europe would also indirectly undergo further harmonisation Even more problematic in this respect are the so-called functional fields of the law. In many European countries private law is rapidly disintegrating into functional fields of law. Usually, these functional fields are the most dynam ic branches of the law labour law. medical law. env ironmental law information law. construction aw to name but a few. Their main characteristic, apart from their functional, pragmatic and non-dogmatic approach, is that they usually contain a mix between private and public lawaspects Some nostalgic civil law scholars will say that all these fields are in essence private law. However, they essentially miss the point. First, because these fields are mixes of private and public law(the relative quantity depending on the politico-economic climate of the day: reguation/deregulation). Secondly, because the approach to the aw in those functional fields is much more pragmatic and less dogmatic. They have, as it were, abandoned the general part of private aw. It would be anachronistic to dissect these fields into a private part, to be regulated on See generally on the Europeanisation of administrative law JH JANS, R. DE LANGE, S RECHAL,RJ.G M.

The new Dutch civil code of 1992 has the characteristics of a classical civil code. 3 The Private/Public Divide The assumption that a civil code deals with all matters of private law and is applicable to all conflicts between private parties is based on another assumption, i.e. that it is possible (and indeed useful) to distinguish between private law and public law. Private law is usually defined as the law which governs relationships between citizens as opposed to public law, which is the law which deals with the relationships between citizens and the state, or among state institutions. However, this clear-cut distinction does give rise to some doubt. Not only as a result of the development of administrative law and, especially, of functional fields of the law which do not seem to fit in very well with this distinction; there is also a more fundamental critique. First, in many countries the cases where the state acts as a private person are problematic. Classical examples include the case where a municipality buys new office equipment. In many countries private law (the civil code) applies directly or by way of analogy to such cases. However, if a European Civil Code were to be enacted, should that code then also apply to (some) national (and European) public authorities? Moreover, in some countries national administrative law and private law are increasingly intertwined. For example, the recent Dutch Algemene Wet Bestuursrecht (1994), which codifies the general part of administrative law, contains many structural and conceptual aspects which resemble the general part of private law (patrimonial law) contained in Books 3, 5, and 6 of the civil code which were enacted in 1992. With the enactment of a European Civil Code this strong link between national private law and national administrative law would be broken. Unless, of course, national administrative law was to be adapted to the new European Civil Code. This would mean, however, that administrative law in Europe would also indirectly undergo further harmonisa tion5 . Even more problematic in this respect are the so-called functional fields of the law. In many European countries private law is rapidly disintegrating into functional fields of law. Usually, these functional fields are the most dynamic branches of the law: labour law, medical law, environmental law, information law, construction law, to name but a few. Their main characteristic, apart from their functional, pragmatic and non-dogmatic approach, is that they usually contain a mix between private and public law aspects. Some nostalgic civil law scholars will say that all these fields are in essence private law. However, they essentially miss the point. First, because these fields are mixes of private and public law (the relative quantity depending on the politico-economic climate of the day: regulation/deregulation). Secondly, because the approach to the law in those functional fields is much more pragmatic and less dogmatic. They have, as it were, abandoned the general part of private law. It would be anachronistic to dissect these fields into a private part, to be regulated on 5. See generally on the Europeanisation of administrative law J.H. JANS, R. DE LANGE, S.

THE STRUCTURE OF THE NEW EUROPEAN PRIVATELAW the European level in a European Civil Code, and a public part, to be regulated on the ational (and maybe sometimes the European or another international)level. In addition, such an approach would also be un-European: the European legislator has not demonstrated any great sensitiv ity to the public/private divide. On the contrary the eu has consistently adopted a functional approach to the aw, in which private law as much as public law is instrumental to the political aims which the EU means to achieve by way of its directives and regulations. The difference between the various Directorates-General of the European Commission seems to have been more detem inant of the structure of European private aw than a dogmatic, esthetical political dedication to the private/public divide As said, private aw is usually defined as the law which governs reltionships between citizens as opposed to public law, which is the law that deals with the relationships between citizens and the state, or among state institutions. This definition is quite descriptive. However, there is another recurrent definition of private law which is much more political. In this definition private law is the law relating to the private area which is free from State intervention In the latter view the only function of private law is allocation: suum cuique tribuere In that view private law has an intemal logic of its own which is politically neutral and is only concemed with giv ing every person what she or he is entitled to. Especially, private aw in that view has no distributionist nor any other paternalistic function: rather it is held that private aw should not be instrumenta lised for political aims. In that view the main pillars of private law are absolute property, freedom of contract and fault liability This view has been forcefully attacked, especially in the United States, by the Sociological, Realist and Critical Legal Studies movements. They challenged the idea that a bsolute property, freedom of contract, fault liability and party autonomy were the natural, apolitical foundations of private law, and they showed that this view of private law was instead closely linked to a laissez-faire Liberal( Conservative) view of the economy and society at large. Instead, they argued that there is no pre-legal entitlement and that all law is public law%. This second definition does indeed seem to be untenable in Europe today. There is no reason to accept any pre-legalright to property or binding force of contract or limitation of liability to fault uld by the courts. Even if( variant of n law or another, that people have pre-legal rights to property, that promises(or agreements)should be binding or that no -one should be liable except when she or he has caused damage by her or his fault, as soon as one is of the opinion that the State should protect and enforce such a right with the aid of the law, the State shall do so only to the extent and in the way agreed upon democratically(including the democratically accepted rigid constitutions and international treaties which protect See further my The New European Legal Culture, p. 37ff Compare Daniela Caruso, The Missing View of the Cathedral: The Private Law Paradigm of European Legal Integration 3 European Law oumal(1997) pp 3-32 See M.

fundamental rights including private property ) Therefore, property is protected promises (agreements)are bindingand people are liable for their torts only when and to the extent that the law says so( Constitutional lawand private law). In that sense all law, including private law, is indeed public law there is no area of the law which free from paternalistic, distributionist and other functional and instrumenta intervention by the State. Also in practice it has become obvious in the course of the 20th century that large parts of private la ware subject to State intervention, which is worker s, tenant s and consumer protection in the special part, whereas objective causation rules, the doctrines of abuse of right and of good faith in the general part have similar effects). Moreover, as said, the whole acquis communautaire is Instrumental, also in the case of private law. These developments raise the question whether it still makes sense to uphold a sharp distinction between private and public law. Moreover, within the English legal system there has never been a strong tradition of distinguishing private law and public law, although some scholrs- who incidenta lly share an interest in Civil Law have recently made use of this term inology. Therefore, it may be worthwhile to go ahead with the functional and piecemealapproach which the European legislator has adopted and to address functional fields of the law rather than to embrace the grand idea of includingall private law within a civil code, and thus reviving a distinction which does not seem desirable neither from a political nor from a practical perspective. Instead, it may be adv isa ble to enact one or more functional European codes, for example in the area of distribution law, company law, or la bour law Civil Law. Commercial Law. Consumer Law Another instance of the fragmentation of private law is not new at all. Indeed, it has been present from the first codif ications the div ision of private law according to the status of the persons involved In many European countries different(or additional) rules apply depending on whether the parties are ordinary citizens or merchants. In addition, more recently a newcategory has developed: the consumer In the first wave of codifications most continental European legal systems dopted both a civil code and a commercial code. However, since the first half of the Oth century the significance of this distinction has gradually decreased. And some countries, notably Italy(1942)and the Netherlands(1992), officially abolished the distinction on the occasion of the implementation of their new civil codes 2 Interestingly, however, during the ast de f the 20th counter-development started to arise asa result of the birth of consumer aw.

Therefore, property is protected, promises (agreements) are binding and people are liable for their torts only when and to the extent that the law says so (Constitutional law and private law). In that sense all law, including private law, is indeed public law: there is no area of the law which is free from paternalistic, distributionist and other functional and instrumental intervention by the State. Also in practice it has become obvious in the course of the 20th century that large parts of private law are subject to State intervention, which is driven by political concerns many of which are distributionist (strict liability, worker s, tenant s and consumer protection in the special part, whereas objective causation rules, the doctrines of abuse of right and of good faith in the general part have similar effects). Moreover, as said, the whole acquis communautaire is instrumental, also in the case of private law. These developments raise the question whether it still makes sense to uphold a sharp distinction between private and public law. Moreover, within the English legal system there has never been a strong tradition of distinguishing private law and public law, although some scholars - who incidentally share an interest in Civil Law - have recently made use of this terminology10. Therefore, it may be worthwhile to go ahead with the functional and piecemeal approach which the European legislator has adopted and to address functional fields of the law rather than to embrace the grand idea of including all private law within a civil code11, and thus reviving a distinction which does not seem desirable neither from a political nor from a practical perspective. Instead, it may be advisable to enact one or more functional European codes, for example in the area of distribution law, company law, or labour law. 4 Civil Law, Commercial Law, Consumer Law Another instance of the fragmentation of private law is not new at all. Indeed, it has been present from the first codifications: the division of private law according to the status of the persons involved. In many European countries different (or additional) rules apply depending on whether the parties are ordinary citizens or merchants. In addition, more recently a new category has developed: the consumer. In the first wave of codifications most continental European legal systems adopted both a civil code and a commercial code. However, since the first half of the 20th century the significance of this distinction has gradually decreased. And some countries, notably Italy (1942) and the Netherlands (1992), officially abolished the distinction on the occasion of the implementation of their new civil codes 12 . Interestingly, however, during the last decades of the 20th century a counter-development started to arise as a result of the birth of consumer law . Thus 10.

THE STRUCTUREOF THE NEW EUROPEAN PRIVATELAW a new distinction arose, between general civil law, which was thought to be largely based on party autonomy, and specific consumer law, which exceptionally was more protective. In the course of the 1980s and 90s in many European countries consumer law developed into an important branch of the law(not least as a result of the many European directives), with a great deal of autonomy vis-a-vis general private law. In France, all consumer regulations have even been brought together in the Code de la Consommation(1997). This development was enhanced by the way in which European Union bureaucracy is organised in Brussels. Different Directorates-General are responsible for the Common Market and for Consumer Protection, a factor which has significantly increased the tendency to enact separate rules for consumers and commercal parties. However, there are also counter-developments: many countries have tried to integrate consumer law into their civil codes as faras possible, thus try ing to mainta in the integrity of civil law A clear example is the 1992 Dutch civil code. Another recent example is the Principles of European Contract Law which were drafted by the Lando Commission and which are meant to apply to all contracts independent of the status of the parties involved 4 There are some strong arguments against schizophrenic European priva te law as Ugo Mattei has called it 5. First, the distinction between consumer contracts and commercial contracts is very problematic. Compare Mattei6: Since there is no such thing as a separate market for consumers(demand) and a separate market for producers(supply ), contract hw has to face the problem of how to merge supply and demand into a single market. The creation of two different bodies of law at odds with each other would ignore this reality, and, as a result, reduce the chance of building efficient private law institutions for modem Europe. Secondly, by(re)introducing hizophrenic contract law the definition and proof of status(consumer professional) becomes all-important, whereas it seems much more efficient to concentra te on contract rather than on status However, adopting uniform European contract aw, as proposed, for example by the Lando commission in its Principles of European Contract Law, carries its own risks as well. That is, if one is concemed that European contract law should be sufficiently socal 7. If contract law is dealt with on a general, abstract level there See for the Netherlands R.P. JL.

In the course of the 1980s and 90s in many European countries consumer law developed into an important branch of the law (not least as a result of the many European directives), with a great deal of autonomy vis-à-vis general private law. In France, all consumer regulations have even been brought together in the Code de la Consommation (1997). This development was enhanced by the way in which European Union bureaucracy is organised in Brussels. Different Directorates-General are responsible for the Common Market and for Consumer Protection, a factor which has significantly increased the tendency to enact separate rules for consumers and commercial parties. However, there are also counter-developments: many countries have tried to integrate consumer law into their civil codes as far a s possible, thus trying to maintain the integrity of civil law. A clear example is the 1992 Dutch civil code. Another recent example is the Principles of European Contract Law which were drafted by the Lando Commission and which are meant to apply to all contracts independent of the status of the parties involved14 . There are some strong arguments against schizophrenic European private law, as Ugo Mattei has called it15. First, the distinction between consumer contracts and commercial contracts is very problematic. Compare Mattei16: Since there is no such thing as a separate market for consumers (demand) and a separate market for producers (supply), contract law has to face the problem of how to merge supply and demand into a single market. The creation of two different bodies of law at odds with each other would ignore this reality, and, as a result, reduce the chance of building efficient private law institutions for modern Europe. Secondly, by (re)introducing schizophrenic contract law the definition and proof of status (consumer or professional) becomes all -important, whereas it seems much more efficient to concentrate on contract rather than on status. However, adopting uniform European contract law, as proposed, for example, by the Lando Commission in its Principles of European Contract Law, carries its own risks as well. That is, if one is concerned that European contract law should be sufficiently social 17. If contract law is dealt with on a general, abstract level there 13. See for the Netherlands R.P.J.L.
