CONSTITUTION, INTERNATIONAL TREATIES, CONTRACTS AND TORTS Martijn van Empel* and Marianne de Jong** IV A 2 Although the title of this paper may seem extremely broad, a very particular topic is addressed in this paper. It focuses on the extent to which the Dutch legal order recognises norms of constitutional and international law as binding not only on the legislative and regulatory authorities, but also on private parties when acting either contractually or unilaterally. In other words, it examines whether constitutional and international law can impose limits on party autonomy under Dutch law. The paper has been divided into four sections. In the first section we will identify the material constitutional and international norms limiting party autonomy which have been applied in cases before Dutch courts concerning contracts and torts. In Section 2 we will elaborate on the manner in which these norms are being enforced before Dutch courts. The method of these norms producing effect as well as the circumstances of enforcement will be discussed. Subsequently, the non-judicial enforcement mechanisms ensuring respect for the constitutional and international limitations will be discussed in Section 3. In Section 4 finally the theoretical underpinnings for the enforcement of the constitutional and international limitations are addressed. 1 Constitutional and international limitations on party autonomy 1.1 Constitutional Norms In this paragraph we will describe whether under Netherlands law and if so, to what extent constitutional norms limit the freedom of a person (a) to enter into contracts with other private parties and (b) to take unilateral legal acts. 1.1.1 Public authority acting as a “private party” Whilst this paper focuses on “priva te parties”, it should be noted that under Netherlands law it is accepted that the State and other public entities are also, subject to certain conditions, subject to the law of contracts and the law of torts, as applicable to private parties in accordance with the Civil Code. In this regard attention should be drawn to Article 3: 14 Civil Code, according to which: “A right which a person has by virtue of the civil law, may not be exercised in violation of the written or unwrittten rules of public law”. It would appear that it is the prevailing opinion that this provision is addressed not to any “person” generally, both public and private, but rather specifically to public * Martijn van Empel is a Professor at LUISS Guido Carli University, Rome and attorney, partner at Stibbe Amsterdam ** Marianne de Jong L.L.M.

VAN EMPEL/DE JONG authorities. Consequently, it may be subm itted that in effect, this provision is onstructed as ensuring that public authorities, also when they act under the guise of private party capacity, should fully comply with their public law duties and respect the specific public law constraints imposed upon them. I An illustrative case in this regard relates to the refusal by a municipality, acting in its capacity as the owner of a theatre, to conclude a contract for a public "hypnosis-show"in that theatre. As it was established that the refusal was based on the finding by the municipality that hypnosis as a public show would not be in accordance with the Christan fath va lues which in that municipa lity were generally shared by the popultion, the Hoge Raad(Netherlands Supreme Court)ruled that this amounted to a ban on the basis of the content of the show and that it was therefore contrary to the fundamental right to the free expression of opinion, as guaranteed in Article 7 of the Constitution (HR 26 April 1996, AB 1996, no 372, m.o. G D. Rasti rastelli") Again, a case where a Congresshall refused to let a room to an association which was deemed to sympathise with South African"Apartheid "gave rise to the issue as to a ossible infringement of the freedom of assembly, as guaranteed under Article 9 of the Constitution. The Court found that it was relevant to the case that 30% of the share capital of the Congresshall was owned by the Municipality of The Hague, lich appointed 50% of the members of the Supervisory Board. In that light the Court expressed doubts as to whether the legal relationship between the Congresshall and the assocation concerned could be qualified as "horizontal. It went on to say If one wishes to confirm this, then one has to admit in any case a horizontal effect of the constitutional fundamental right".On that basis an injunction was issued to waive the tortuous refusal President Rechtbank(District Court) The hague, 9 June 1987,AB1987,580) Another noteworthy judgment in this regard is that of the Court of Appeals Leeuwarden of 1983, in which the latter found that public authority may make use of private law(contractual)means beyond what would be allowed under its public law powers, provided it would not, had it acted on a public law basis, have acted in olation of a provision of a higher rank, such as in casu Article 10, par 2, of the uropean Convention of Human Rights(ECHR)(Court of Appeals Leeuwarden, 23 March1983,AB1983,336) 1. 1. 2 Private parties as such As mentioned above it is generally understood that Article 3: 14 Civil Code is not addressed to private parties as such. As far as the latter are concerned, the issue has to be addressed on a different basis. therefore The issue as to what is the proper legal basis for the effects of constitutional and international noms, more particular fundamental human rights, on relations between private parties will be addressed in Section IV below. At this stage it seems adequate for the purpose of relating the state of affa irs in practice, to refer to this as the issue of horizontal effects offundamental human rights See JC.E.

Consequently, it may be submitted that in effect, this provision is constructed as ensuring that public authorities, also when they act under the guise of private party capacity, should fully comply with their public law duties and respect the specific public law constraints imposed upon them.1 An illustrative case in this regard relates to the refusal by a municipality, acting in its capacity as the owner of a theatre, to conclude a contract for a public “hypnosis-show” in that theatre. As it was established that the refusal was based on the finding by the municipality that “hypnosis as a public show would not be in accordance with the Christian faith values which in that municipality were generally shared by the population”, the Hoge Raad (Netherlands Supreme Court) ruled that this amounted to a ban on the basis of the content of the show and that it was therefore contrary to the fundamental right to the free expression of opinion, as guaranteed in Article 7 of the Constitution. (HR 26 April 1996, AB 1996, no. 372, m.o.v. Th.G.D. Rasti Rostelli”) Again, a case where a Congresshall refused to let a room to an association which was deemed to sympathise with South African “Apartheid” gave rise to the issue as to a possible infringement of the freedom of assembly, as guaranteed under Article 9 of the Constitution. The Court found that it was relevant to the case that 30% of the share capital of the Congresshall was owned by the Municipality of The Hague, which appointed 50% of the members of the Supervisory Board. In that light the Court expressed doubts as to whether the legal relationship between the Congresshall and the association concerned could be qualified as “horizontal”. It went on to say: “If one wishes to confirm this, then one has to admit in any case a horizontal effect of the constitutional fundamental right”. On that basis an injunction was issued to waive the tortuous refusal (President Rechtbank (District Court) The Hague, 9 June 1987, AB 1987, 580). Another noteworthy judgment in this regard is that of the Court of Appeals Leeuwarden of 1983, in which the latter found that public authority may make use of private law (contractual) means beyond what would be allowed under its public law powers, provided it would not, had it acted on a public law basis, have acted in violation of a provision of a higher rank, such as in casu Article 10, para 2, of the European Convention of Human Rights (ECHR) (Court of Appeals Leeuwarden, 23 March 1983, AB 1983, 336). 1.1.2 Private parties as such As mentioned above it is generally understood that Article 3: 14 Civil Code is not addressed to private parties as such. As far as the latter are concerned, the issue has to be addressed on a different basis, therefore. The issue as to what is the proper legal basis for the effects of constitutional and international norms, more particula r fundamental human rights, on relations between private parties will be addressed in Section IV below. At this stage it seems adequate for the purpose of relating the state of affairs in practice, to refer to this as the issue of horizontal effects of fundamental human rights. 1. See J.C.E.

CONSTITUTION, INTERNATIONAL TREATIES, CONTRACTS AND TORTS It would appear fair to say, that the courts in The Netherlands tended, through the years, to be rather reticent in their recognition of"horizontal effect". It should be stressed, however, that this did not leave necessarily the sub stance of fundamental rights unprotected at ahorizontal"level. Rather, reference was made, in some instances, to general principles and an equitable balancing of interests. Examples of such approach may be found in the following cases It has been established that a religious congregation acting as landlord cannot refuse to renew a lease contract with a tenant on the ground that the latter has ceased being a member of that congregation. Rather than a direct reference to the freedom of religion(Article 6, Constitution)this judgment was based on an equitable balancing of interests of both sides. In this regard it should be noted that the court distinguished between a situation where a lease contract would be concluded for the first time and that of a renewal of such contract. the interest of the lessee clearly being of more relevance in the katter case as opposed to the fomer.(Hof(Court of Appeal) Arnhem 15-11-1958, NJ 1959, 472, Hof Arnhem 24 June 1958, NJ 1959, 473) The freedom of education(Article 23(2), Constitution)was at issue in a case where it had been stipulated in a contract that under certain specif circumstances one party to the contract would be barred from certa in teaching activities("Mensendieck ) Again, the case was adjudged in terms of"public order and faimess"("openbare orde en goede zeden), rather than those of a direct applicability of the fundamental right to education as enshrined in the Constitution(HR 31 October 1969, NJ 1970, 57, m o.v. GJS)(a second dgment by the Hoge Raad in the same litigation rehted to the First Protocol of the ECHr, see p 7) On the other hand, in that same period an instance of an explicit reference to a fundamental right is to be found in a judgment of the Court of Appeals in Amsterdam of 30 October 1980(NJ 1981, 422). In that case the court held that was an infringement of the freedom of expression although this refusal was based on reasons related to the form, rather than to the content( "Outspan") In some other cases, the courts appeared prepared to hear argument based on fundamental rights but d ism issed the claims on the facts Aga inst that background it is interesting to note that at the occasion of the revision of the Constitution which entered into force in 198, not only was a catalogue of fundamental rights" put into prominence at the beginning of the text of the Constitution. but also the issue of "horizontal effect was addressed in the parliamentary discussions as a specific issue. Whilst it would seem that there was consensus as to a more flexible approach to the issue of horizontal effect", no clear guidelines could be distilled from the debates and the issue was in effect left to be dealt with by the courts on a case-by-case basis As it is, as from 1984, whilst the courts may have been more inclined to act upon a horizontal effect of fundamental rights, this by no means meant that this was now
CONSTITUTION,INTERNATIONAL TREATIES,CONTRACTS AND TORTS 3 It would appear fair to say, that the courts in The Netherlands tended, through the years, to be rather reticent in their recognition of “horizontal effect”. It should be stressed, however, that this did not leave necessarily the substance of fundamental rights unprotected at a “horizontal” level. Rather, reference was made, in some instances, to general principles and an equitable balancing of interests. Examples of such approach may be found in the following cases: - It has been established that a religious congregation acting as landlord cannot refuse to renew a lease contract with a tenant on the ground that the latter has ceased being a member of that congregation. Rather than a direct reference to the freedom of religion (Article 6, Constitution) this judgment was based on an equitable balancing of interests of both sides. In this regard it should be noted that the court distinguished between a situation where a lease contract would be concluded for the first time and that of a renewal of such contract, the interest of the lessee clearly being of more relevance in the latter case as opposed to the former. (Hof (Court of Appeal) Arnhem 15-11-1958, NJ 1959, 472; Hof Arnhem 24 June 1958, NJ 1959, 473). - The freedom of education (Article 23(2), Constitution) was at issue in a case where it had been stipulated in a contract that under certain specific circumstances one party to the contract would be barred from certain teaching activities (“Mensendieck”). Again, the case was adjudged in terms of “public order and fairness” (“openbare orde en goede zeden”), rather than those of a direct applicability of the fundamental right to education as enshrined in the Constitution. (HR 31 October 1969, NJ 1970, 57, m.o.v. G.J.S.) (a second judgment by the Hoge Raad in the same litigation related to the First Protocol of the ECHR, see p.7). - On the other hand, in that same period an instance of an explicit reference to a fundamental right is to be found in a judgment of the Court of Appeals in Amsterdam of 30 October 1980 (NJ 1981, 422). In that case the court held that under the circumstances a refusal to accept an anti-Apartheid advertisement, was an infringement of the freedom of expression although this refusal was based on reasons related to the form, rather than to the content (“Outspan”). In some other cases, the courts appeared prepared to hear argument based on fundamental rights but dismissed the claims on the facts. Against that background it is interesting to note that at the occasion of the revision of the Constitution which entered into force in 1983, not only was a catalogue of “fundamental rights“ put into prominence at the beginning of the text of the Constitution, but also the issue of “horizontal effect” was addressed in the parliamentary discussions as a specific issue. Whilst it would seem that there was consensus as to a more flexible approach to the issue of “horizontal effect”, no clear guidelines could be distilled from the debates and the issue was in effect left to be dealt with by the courts on a case-by-case basis. As it is, as from 1984, whilst the courts may have been more inclined to act upon a “horizontal effect” of fundamental rights, this by no means meant that this was now
VAN EMPEL/DE JONG the dominant line. Accordingly, there is a mixed harvest of cases, some making specific reference to one fundamental right or another, others rely ing on the more classic"balancing of interests within the canons of interpretation. An instance of the fomer is the judgment of the Court of Appeal, Amsterdam of 17 February 1984(NJ 1985, 96). It was alleged that the defendant Electricity company acted in tort in that it discrim inated aga inst certa n migrant persons living in campers by requiring certa in additional contractual guarantees as a condition for the supply of electricity to those persons On the facts it was established by the court that there was no instance here of treating cases differently, as would have been prohibited by virtue of Article 1. Const tution On the other hand, in its judgment of 30 March 1984 (Inan v De venhorst, AB 1984 366)the Hoge Raad tested a claim for unfair dism issa because of absence from work forreligious reasons, not directly against the fundamental right to freedom of religion, but rather assessed whether this absence could be deemed a"pressing reason for dismissal under labour law provisions of the Civil Code A typical instance of judicial discretion in this regard is to be found in the Hoge Raad's judgment on a plea to the effect that the fundamental right to a free choice of work implied that an explicit written stipulation in the labour contract would be required under the circumstances of the case. The Court held that this view would grant to this fundamental right a wider horizontal effect than would be warranted (HR I July 1997, NJ 1997, 695, Kolkman) To wind up on this section, attention should be drawn to the sequence of judgments in what is referred to as the"aids -test case". This related to a case of rape where the victim fearing that she might have been infected with Hiv first had herself tested with negative outcome), but was then informed that for a conclusive result she would have to be tested a second time Not beingable to face the psychological stress of a second test she then sued for the perpetrator of the rape to have himself tested, on his part, which the latter refused to do. As it is, each side in the ensuing legal battle relied for its part on the same fundamental human right enshrined in the Constitution, in respectively Article 10(respect for private life)and Article 1 1(inviolability of the human body) In the first instance the court recognised that each side indeed could rely on those fundamental rights and that accordingly the respective interests of each side had to be weighted a ga inst each other. On that basis it found for the plaintiff (the victim of the rape).(Pres. District Court Amsterdam, 1l July 1991, KG 1991, 242: NJCM Bulletin 16.6(1991), p 560ev, m.n. A Sas) On appeal the Court of Appeals in Amsterdam appears to deny that in the issue of obta ining conclusive ev idence on the ads-risk as a consequence of the rape the fundamental human rights of the victim of the rape areat stake, which leaves only the defendant in a position to rely on his fundamental rights not to be subjected to a HIV-test against his will. Accordingly, the action by the victim of the rape was dismissed. Court of Appeals Amsterdam, 5 March 1992, RN 1992, 296) On further appeal(cassation)the Hoge Raad, however, in its turn found for the
VAN EMPEL/DE JONG 4 the dominant line. Accordingly, there is a mixed harvest of cases, some making specific reference to one fundamental right or another, others relying on the more “classic” balancing of interests within the canons of interpretation. An instance of the former is the judgment of the Court of Appeal, Amsterdam of 17 February 1984 (NJ 1985, 96). It was alleged that the defendant Electricity company acted in tort in that it discriminated against certain migrant persons living in campers by requiring certain additional contractual guarantees as a condition for the supply of electricity to those persons. On the facts it was established by the court that there was no instance here of treating cases differently, “as would have been prohibited by virtue of Article 1, Constitution” On the other hand, in its judgment of 30 March 1984 (Inan v De Venhorst, AB 1984, 366) the Hoge Raad tested a claim for unfair dismissal because of absence from work for religious reasons, not directly against the fundamental right to freedom of religion, but rather assessed whether this absence could be deemed a “pressing reason for dismissal” under labour law provisions of the Civil Code. A typical instance of judicial discretion in this regard is to be found in the Hoge Raad’s judgment on a plea to the effect that the fundamental right to a free choice of work implied that an explicit written stipulation in the labour contract would be required under the circumstances of the case. The Court held that “this view would grant to this fundamental right a wider horizontal effect than would be warranted” (HR 1 July 1997, NJ 1997, 695, Kolkman). To wind up on this section, attention should be drawn to the sequence of judgments in what is referred to as the “aids-test case”. This related to a case of rape where the victim fearing that she might have been infected with HIV first had herself tested (with negative outcome), but was then informed that for a conclusive result she would have to be tested a second time. Not being able to face the psychological stress of a second test she then sued for the perpetrator of the rape to have himself tested, on his part, which the latter refused to do. As it is, each side in the ensuing legal battle relied for its part on the same fundamental human right enshrined in the Constitution, in respectively Article 10 (respect for private life) and Article 11 (inviolability of the human body). - In the first instance the court recognised that each side indeed could rely on those fundamental rights and that accordingly the respective interests of each side had to be weighted against each other. On that basis it found for the plaintiff (the victim of the rape). (Pres. District Court Amsterdam, 11 July 1991, KG 1991, 242; NJCM Bulletin 16.6 (1991), p. 560 e.v., m.n. A. Sas). - On appeal the Court of Appeals in Amsterdam appears to deny that in the issue of obtaining conclusive evidence on the aids-risk as a consequence of the rape the fundamental human rights of the victim of the rape are at stake, which leaves only the defendant in a position to rely on his fundamental rights not to be subjected to a HIV-test against his will. Accordingly, the action by the victim of the rape was dismissed. (Court of Appeals Amsterdam, 5 March 1992, RN 1992, 296). - On further appeal (cassation) the Hoge Raad, however, in its turn found for the
CONSTITUTION, INTERNATIONAL TREATIES, CONTRACTS AND TORTS plaintiff. The supreme court based itself on the finding that both sides could indeed each rely on the fundamental human rights referred to and accordingly, in order to come to a solution of the conflict, a concession on the right of one of the opposing parties had to be accepted Whereas the Court of First Instance had not further explicited the basis for its weighting of the interests at stake, the Hoge Raad for its part held that the concession to be relating to tort law under the Civil Code. More particularly, the cout relie es required from one of the opposing parties had to be based on the principles the principle that the perpetrator a tort -action is bound in law to lim it as much he can the damaging consequences of his action. On that basis, derived from civil law, the fundamental human right of the defendant, enshrined in the Constitution had to suffer an exception in the case at hand(Hoge Raad, 18 June 1993, RvdW 1993, 136: NJ NJCM Bulletin 18-7-(1993)p. 786 m.n. L.F.M 1.2 International norms In this paragraph we will address the question whether under Netherlands law and if so, to what extent international norms lim it the freedom of a person(a)to enter into contracts with other private parties and (b)to take unilateral legalacts With regard to this question it should be stressed in the first place that th Netherlands Constitution expressis verbis provides for the precedence of directly effective binding provisions of international treaties and of decisions of public international law organisations(Articles 93 and 94). Accordingly the Dutch courts are bound to assess the possible conflict between self executing provisions of those international law instruments and provisions of Netherands national law. On the er hand, non-written public intermational law and non-self executing provisions of written public international law instruments will not be taken into account on the ame basis(hr 6 March 1959, NJ 1962, no. 2).2 impact which the law of the European Union, more particularly the lw of the uropean Community(fomerly the European Econom ic Community has had on the legal relations between private parties in the Netherlands. Indeed, that body of law permeated the Dutch legal system in such detail and in such scope that any meaningful discussion would require a separate report in its own right. Just to mention two instances, both with regard to competition awas well as the labour w regime as to the equal treatment of men and women the position of private parties has been fundamentally affected by EC law as it has developed over the years. Perhaps more mportant in this regard is the consideration that the body of ec law does not for its effect in Dutch aw, depend on the provisions of the Dutch Constitution(see Court of Justice, 5 February 1963, Case 26/62, (1993)ECR 1, (Van Gend loos) and 15 July 1964, Case 6/64, (1964)ECR 585 (Costa/ENEL ) For that matter, the Dutch courts have generally accepted the doctrines of autonomy and supremacy of EC Law as well as the enforcement mechanisms of direct effect. conform More on the technique of enforcing intemational norms in the Dutch context p 1 1-16

The supreme court based itself on the finding that both sides could indeed each rely on the fundamental human rights referred to and that accordingly, in order to come to a solution of the conflict, a concession on the right of one of the opposing parties had to be accepted. Whereas the Court of First Instance had not further explicited the basis for its weighting of the interests at stake, the Hoge Raad for its part held that the concession to be required from one of the opposing parties had to be based on the principles relating to tort law under the Civil Code. More particularly, the court relied on the principle that the perpetrator of a tort-action is bound in law to limit as much he can the damaging consequences of his action. On that basis, derived from civil law, the fundamental human right of the defendant, enshrined in the Constitution had to suffer an exception in the case at hand (Hoge Raad, 18 June 1993, RvdW 1993, 136; NJ NJCM Bulletin 18-7-(1993) p. 786 m.n. L.F.M. Verhey). 1.2 International norms In this paragraph we will address the question whether under Netherlands law and if so, to what extent international norms limit the freedom of a person (a) to enter into contracts with other private parties and (b) to take unilateral legal acts. With regard to this question it should be stressed in the first place that the Netherlands Constitution expressis verbis provides for the precedence of directly effective binding provisions of international treaties and of decisions of public international law organisations (Articles 93 and 94). Accordingly the Dutch courts are bound to assess the possible conflict between self executing provisions of those international law instruments and provisions of Netherlands national law. On the other hand, non-written public international law and non-self executing provisions of written public international law instruments will not be taken into account on the same basis (HR 6 March 1959, NJ 1962, no. 2).2 Within the context of the present paper it has been decided to leave undiscussed the impact which the law of the European Union, more particularly the law of the European Community (formerly the European Economic Community) has had on the legal relations between private parties in the Netherlands. Indeed, that body of law permeated the Dutch legal system in such detail and in such scope that any meaningful discussion would require a separate report in its own right. Just to mention two instances, both with regard to competition law as well as the labour law regime as to the equal treatment of men and women the position of private parties has been fundamentally affected by EC law as it has developed over the years. Perhaps more important in this regard is the consideration that the body of EC law does not for its effect in Dutch law, depend on the provisions of the Dutch Constitution (see Court of Justice, 5 February 1963, Case 26/62, (1993) ECR 1, (“Van Gend & Loos”) and 15 July 1964, Case 6/64, (1964) ECR 585 (“Costa/ENEL”). For that matter, the Dutch courts have generally accepted the doctrines of autonomy and supremacy of EC Law as well as the enforcement mechanisms of direct effect, conform 2.
