Introduction
Many contractual disputes begin with the same argument: the parties agree that a contract exists, but not on what exactly was agreed. One party points to the literal wording, the other to what was discussed during the negotiations or how the contract was performed over many years. Dutch law does not resolve that conflict with a single rule, but with a standard that weighs all the circumstances of the case. Understanding how that standard works tells a party which evidence counts and what an interpretation dispute actually turns on.
The Haviltex standard: more than the literal wording
Since the Haviltex judgment, the starting point has been that the interpretation of a contract does not turn on a purely textual reading of its provisions alone. What matters is the meaning that the parties could reasonably attribute to those provisions in the given circumstances, and what they could reasonably expect of each other in that respect (Supreme Court 13 March 1981, ECLI:NL:HR:1981:AG4158, Haviltex). The social circles to which the parties belong and the legal knowledge that may be expected of such parties can also be relevant.
All the circumstances of the case may therefore carry weight: what was discussed before the contract was concluded, how the parties conducted themselves afterwards, who drafted the text and whether the parties were assisted by legal advisers. The textual meaning of the wording remains relevant, but is not decisive without more. The same standard serves to identify and fill gaps in a contract. Where the agreement is silent, the gap is filled in line with what the parties could reasonably expect, having regard to the supplementary effect of reasonableness and fairness (Section 6:248(1) of the Dutch Civil Code, DCC).
Textual interpretation between professional parties
In commercial contracts between professional parties, the textual meaning carries more weight. Where the contract is extensive, detailed and fully negotiated, concluded with the assistance of lawyers and containing an entire agreement clause, the court may, as a starting point, attach decisive weight to the most obvious textual meaning of the wording, read in the light of the other provisions (Supreme Court 19 January 2007, ECLI:NL:HR:2007:AZ3178, Meyer Europe/PontMeyer). That finding is provisional: the party advancing a different interpretation is admitted to rebuttal evidence.
This starting point is not automatic. It rests on the assumption that the parties actually negotiated and were professionally assisted while doing so. If those assumptions are incorrect, for example because the text was not negotiated, one party had no lawyer, or the contract is a unilaterally drafted model agreement, the reason to attach great weight to the wording falls away (Supreme Court 5 April 2013, ECLI:NL:HR:2013:BY8101, Lundiform/Mexx). Even where great weight attaches to the wording, the other circumstances of the case may require a meaning other than the textual one. The Haviltex standard always remains decisive.
The entire agreement clause
An entire agreement clause provides that the contract sets out the parties' complete agreement and supersedes earlier arrangements. Such a clause originates in the Anglo-American legal tradition and has no special meaning without more under Dutch law. It is not, in itself, an interpretation provision. The clause can be a relevant circumstance in interpretation, where account is taken of its wording, the nature and level of detail of the contract, and the way in which the clause came up during the negotiations (Lundiform/Mexx, para. 3.5.3). The clause does not, without more, preclude attaching meaning, for interpretation purposes, to statements made or conduct engaged in before the contract was concluded.
In practice, such a clause reinforces the weight of the text without excluding Haviltex. In a case concerning indemnity claims in a business acquisition, reliance on an oral stipulation failed against a detailed, fully negotiated contract. The chosen wording was decisive there.
The CAO standard and the sliding scale
Alongside the Haviltex standard there is the CAO standard, under which the wording, read in the light of the text as a whole, is in principle decisive. That standard applies to documents which by their nature are intended to affect the legal position of third parties without those parties having had any influence on the text, and without the parties' intention being knowable to them, such as a collective labour agreement, a social plan or a pension scheme. There is no opposition between the two standards, but a gradual transition (Supreme Court 20 February 2004, ECLI:NL:HR:2004:AO1427, DSM/Fox).
Their common basis is that all the circumstances of the case are decisive for interpretation, assessed by the standards of reasonableness and fairness. The arguments for an objective interpretation gain weight to the extent that the document is intended to govern the legal position of third parties. The CAO standard, too, does not lead to a purely textual interpretation. For the interpretation of articles of association and general terms and conditions that bind an indeterminate class of third parties, the objective pole of this sliding scale therefore lies closer than for an individually negotiated contract.
Evidence
Interpretation disputes almost always turn on evidence. Who can demonstrate what was intended? Internal e-mails, draft versions of the contract, notes of discussions and the actual performance of the agreement can make the difference. A party advancing an interpretation other than the textual one bears the burden of proof, or must be admitted to rebuttal evidence (Article 150 of the Dutch Code of Civil Procedure, DCCP). Preserving a record of the negotiations is therefore advisable not only once a dispute looms, but already during the negotiation process itself.
Questions of interpretation regularly arise in disputes concerning non-performance and (ir)regular termination. The way in which a provision is interpreted determines whether a party has performed its obligations or has instead fallen short. In a case concerning record contracts and streaming, the central question was whether digital exploitation qualified as licensing to third parties, a pure question of interpretation, which the court decided on the basis of the most obvious textual meaning.
What decides the outcome
The outcome of an interpretation question is decided by the standard, Haviltex or a more textual reading between professional parties, and by the evidence of the parties' intention. A party that maps the context, the negotiations and the nature of the parties sharply determines how a disputed clause is read.
