Refusal of a certificate of authenticity:
the committee's freedom of opinion prevails over the collector's property right

By a judgment of 7 May 2026, the Paris Civil Court declines to compel an association devoted to preserving the work of a major twentieth-century artist to issue a certificate of authenticity for a signed replica acquired at Sotheby's in 1988. The firm sets out three guiding principles that market participants must integrate: no legal obligation requires an artist's committee to certify a work, even an authentic one; the committee's opinion falls within the freedom of expression protected by article 10 of the ECHR; and a collector who sues a committee to obtain an opinion contrary to its conviction commits an abuse of the right to bring proceedings. A signal ruling for authentication committees, auction operators and informed collectors.

An artist's committee gives an opinion: it does not sign an expert's contract

At the heart of the dispute lies a signed urinal, bought at a New York auction in 1988 for 62,500 dollars, presented as a ready-made by a pivotal twentieth-century artist and dated 1964. Thirty years later, its owner entrusts its resale to Sotheby's. The auction house consults the association whose purpose is the defence and preservation of the artist's work: by two emails dated 9 February and 27 March 2019, the association expresses a reasoned unfavourable opinion. The collector, considering that the item corresponded to the prototype of a limited edition produced in 1964 under a contract with a gallery owner, sues the association to obtain, as its principal claim, the delivery of a certificate of authenticity under penalty payment; in the alternative, twelve million dollars in damages.

The court dismisses the claim in its entirety. Three lines of reasoning structure the decision. First, the consultation between the auction operator and the association does form a contract, an agreement of intentions within the meaning of article 1101 of the Civil Code, but the delivery of a certificate of authenticity, distinct from a mere opinion, presupposes an express stipulation, an identified paid service, and a purpose of being relied upon against third parties. None of these markers being present here, the collector, himself a third party to the consultation, is the creditor of no delivery obligation.

Second, the committee's opinion, whether favourable or unfavourable, falls within the freedom of expression of article 10 §1 of the ECHR. Restricting it presupposes a pressing social need within the meaning of Strasbourg case law. A collector's ability to put his property up for auction does not fall into that category, even where it is backed by the property right of article 1 of Additional Protocol No. 1.

Third, the court characterises the action itself as an abuse of the right to bring proceedings: suing an association to compel it to adopt an opinion contrary to its conviction amounts to infringing one of its fundamental freedoms. The penalty takes three forms, EUR 5,000 in damages, a EUR 10,000 civil fine, and EUR 25,700 under article 700 of the Code of Civil Procedure, against an expected loss of twelve million. The message to the market is free of ambiguity.

Five operative lessons for the art market

Beyond this single dispute, the firm identifies five guiding principles that collectors, committees, gallery owners and auction operators must build into their practices.

1. A consultation forms a contract, but does not create an obligation to certify

The exchange between the auction operator and the committee, once it concerns the authenticity of an item whose defence is precisely the committee's corporate purpose, is enough to give shape to an agreement of intentions (Civil Code art. 1101 and 1103). But certifying, that is, issuing an act capable of engaging the certifier's liability towards third parties, requires more: an express reference to the certificate, an identified paid service, a purpose of being relied upon by purchasers. Failing that, the committee has agreed only to give an opinion.

2. Third party to the contract: the breach must be proved, not assumed

Since the collector is not a party to the consultation between the auction operator and the committee, his claim for compensation follows the path traced by Civ. 1st 26 February 2025 no. 23-21.522: a third party may invoke a contractual breach on the tort basis, but it is for him to establish that breach and the resulting harm. The mere refusal of a certificate, where no delivery obligation exists, is not a breach.

3. The committee's freedom of opinion: the ECHR standard applies

The opinion of an authentication committee is an opinion. Absent a special characterisation (the Act of 18 July 1881, established disparagement), it benefits from the protection of article 10 §1 of the ECHR. Restricting it presupposes a pressing social need (ECHR, Verein gegen Tierfabriken v. Switzerland, 30 June 2009, no. 32772/02). The possibility of reselling an item at auction is not one, however considerable the economic value at stake may be.

4. The publishing contract sets the scope of the reproductions that can be authenticated

Where an artist assigns to a gallery owner, by a publishing contract, the right to reproduce a work in a limited and numbered edition, any additional copy, even a signed one, falls by definition outside the contractual object. A committee that gives priority to the terms of the contract, concluded during the artist's lifetime, over a signature appearing after death commits no fault. The hierarchy of authentication criteria is a matter for the committee's free choice, provided it documents its approach.

5. Abuse of the right to bring proceedings threatens instrumental actions

The court characterises the abuse under article 32-1 CPC in combination with article 1240 of the Civil Code: suing to compel an association to adopt an opinion contrary to its conviction diverts the right to bring proceedings from its purpose. The penalty combines damages (EUR 5,000), a civil fine (up to EUR 10,000, the statutory ceiling reached here), and substantial non-recoverable costs (EUR 25,700). The disappointed collector has other avenues, notably annulment of the initial sale, that do not bring into play his opponent's fundamental freedom of opinion.

Our approach at the firm

The firm acts at every stage of a work's life cycle: upstream structuring (acquisition, provenance due diligence, tax characterisation within the meaning of article 98 A of Annex III to the French Tax Code and article L.122-8 CPI), operational monitoring (relations with authentication committees, auction operators, insurers), and defence in the event of a dispute (rescission, authenticity guarantee, expert liability).

On resale operations involving an artist's committee, the firm secures in advance the nature of the consultation sought, a mere opinion or an enforceable certificate, the capacity of the party requesting it (auction operator, owner in his own name, agent), and the resulting contractual documentation. This ex ante discipline avoids the situation to which the collector exposed himself in the case discussed: believing in the existence of an obligation founded on neither statute nor contract.

For the committees, foundations and rightholders that defend an artist's work, the firm documents opinion protocols (criteria, process, traceability), certificate policy (terms, pricing, enforceability), and litigation strategy in the face of instrumental actions, which are multiplying as markets tighten.

— Frequently asked questions

What the decision of 7 May 2026 changes in practice

Is an artist's committee obliged to authenticate a work I submit to it?

No. No legal provision, general contractual rule or professional custom obliges an association whose purpose is the defence and preservation of an artist's work to issue a certificate, or even an opinion, on a work submitted to it. The decision of 7 May 2026 expressly recalls this: « no legal obligation requires an association whose purpose is the preservation and defence of an artist's work to certify that artist's works, even authentic ones ». The request remains free; so does the answer.

If the committee accepts the consultation, must it go so far as to issue a certificate?

Not necessarily. An accepted consultation gives shape to a contract, an opinion was requested, an opinion was given, but it is not enough to found an obligation to deliver a separate certificate of authenticity, which engages the certifier's liability towards third parties. For that obligation to exist, there must be an express stipulation, an identified and priced service, and a purpose of external enforceability. Failing that, the committee has undertaken only to give its opinion.

What are the committee's obligations when it agrees to give an opinion?

Once the consultation is accepted, the committee is bound by a contractual obligation of good faith, objective information and best efforts in seeking and gathering the elements enabling it to form its opinion. The decision makes clear that no rule imposes an a priori hierarchy among the analysis criteria: the committee may legitimately give priority to the terms of a publishing contract concluded during the artist's lifetime over a signature appearing after death, provided it documents its approach. Methodological rigour, not the conclusion reached, is the yardstick of judicial review.

Can the property right prevail over the committee's freedom of expression?

Not in the absence of a pressing social need. The court carries out the balancing exercise required by ECHR case law (Beyeler v. Italy, 5 Jan. 2000, no. 33202/96; Ališić and others v. Bosnia and Herzegovina, Croatia, Serbia, Slovenia and the former Yugoslav Republic of Macedonia [GC], 16 July 2014, no. 60642/08). The ability to put an item up for public auction, even one valued at twelve million dollars, does not raise the property right to the rank of a higher interest. Only a specifically defined statute (the Act of 18 July 1881, disparagement) can bound the committee's freedom of opinion.

What remedies for a collector disappointed by a committee's unfavourable opinion?

Several avenues, distinct from one another: (1) annulment of the initial sale on the basis of mistake as to substantial qualities or of fraud (Civil Code art. 1130 et seq.), an avenue open if the acquisition was made on inaccurate representations; (2) claiming the liability of the expert or the auction operator in respect of the original sale; (3) a fresh consultation with a qualified independent expert, the decision recalling that a certificate may result from an examination by such an expert; (4) an action for unfair competition or disparagement against the committee, but subject to the strict condition of establishing a legal exception to the freedom of opinion. The action to compel delivery of the certificate, by contrast, is bound to fail.

Can the original publishing contract found an authentication obligation?

No, absent an express stipulation to that effect. The publishing contract assigns to the gallery owner a reproduction right limited in its scope, number of copies, numbering, artist's signature. Any additional copy falls by definition outside the contractual object: it does not come within the scope of any authentication obligation, even where the committee is the artist's rightholder. The contract protects the work against out-of-series copies; it does not found a duty to validate them.

Why does the court characterise the action as abusive and impose the maximum civil fine?

The court finds two distinct faults: (1) a blameworthy carelessness, the collector could not seriously believe that an exchange of private emails had given rise to a delivery obligation; (2) a diversion of the right to bring proceedings, the action sought to compel the association to adopt an opinion contrary to its conviction, thus to infringe its fundamental freedom. The maximum civil fine of EUR 10,000 (CPC art. 32-1) is proportionate to the seriousness of the abuse and to the expected loss of twelve million dollars. The signal sent to the market is powerful: instrumentalising the judge to compel an opinion exposes a party to a threefold penalty, damages, fine and non-recoverable costs.
