By Lokesh Vyas and Yogesh Badwal. This post was originally published on Spicy IP. Bonjour, Lately, we’ve been cogitating on this curious concept called the “opt-out”, which has been cropping up with increasing frequency in generative AI litigation, including in India. The EU and the UK are taking the idea seriously and considering giving it statutory teeth. On the surface, it is sold as a middle path, a small price to pay for “balance” in the system. However, at least prima facie, it seems like a legal absurdity that fractures its modern foundational logic, where authors receive default copyright without any conditions. The opt-out model, the argument goes, reintroduces formality through the back door, a de facto formality of sorts. This shifts the burden onto authors and rights holders to actively monitor or manage their works to avoid unintended inclusion in the AI training. There have been questions about whether such an opt-out scheme is compatible with the Berne Convention, which prohibits the same under Article 5(2), e.g., here, here, and here.  Given the complex nature of this issue and the fact that many such discussions happen behind paywalls, making them inaccessible to the public, we thought it would be beneficial to share our ideas on this topic and invite further reflection. This two-part post mainly focuses on the legality of opting out without addressing its implementability and applicability, which raises several questions (e.g., as discussed recently in Martin Sentfleben’s post). In short, we probe whether opt-outs violate the Berne Convention—the first international copyright law treaty binding on all members of the TRIPS and WCT.  We answer it through two questions and discuss each one separately. First, is opt-out a prohibited formality for the “enjoyment and exercise” of authors’ rights under Article 5(2) of the Berne Convention? Two, can it be permitted as an exception under the three-step test under Article 9(2)? We answer the first question in the negative and the second in the positive. Additionally, we also examine whether Berne already has a provision that can allow this without looking at the details.  This post addresses the first question. What Makes Opts Outs So Amusing – The Flip? Many generative AI models are trained on vast datasets, which can also include copyrighted works scraped from the internet without the explicit consent of content creators, raising legal, ethical, and normative concerns. To address this, some AI developers have created and claimed “opt-out mechanisms,” allowing copyright holders or creators to ask that their works not be used in training (e.g., OpenAI’s Policy FAQs).  Herein lies the catch: it requires authors and copyright holders to explicitly say “No” to training by adding a robots.txt tag to their website with specific directives that disallow web crawlers from accessing their content. (E.g., see this OpenFuture’s guide here) Thus, instead of creators being protected by default, they are supposed to opt out to prevent exploitation. One could say that this flips the logic of copyright on its head–from a presumption of protection to a presumption of permission. But that’s not so simple.  Notably, opting out is not a novel argument. In fact, it can be dated back at least to the 1960s in the Nordic countries’ model of “Extended Collective Licensing” (ECL), which mandates collective licensing while preserving the author’s right to opt out. Other notable academic literature on opt-out can be found here, here, here, and here, dating back over two decades. Swaraj also covered this issue a decade ago. In particular, we must acknowledge the scholarship of Jane Ginsburg, Martin Sentfleben, and Stef van Gompel, who have significantly influenced our thinking on the topic. Two Key Questions: Opt out as a Formality and opt out under a permitted Exception Formality Argument first.  Here, the argument goes that the opt-out is a prohibited formality under Article 5(2) and should not be allowed. However, we doubt it. Let’s parse the provision first. Which states: “(2) The enjoyment and the exercise of these rights shall not be subject to any formality; such enjoyment and such exercise shall be independent of the existence of protection in the country of origin of the work. Consequently, apart from the provisions of this Convention, the extent of protection, as well as the means of redress afforded to the author to protect his rights, shall be governed exclusively by the laws of the country where protection is claimed.” (Authors’ emphasis) For context, the provision pertains to “Rights Guaranteed outside the Country of Origin” for both national and foreign authors. And the question of no-formality pertains particularly to foreign authors. In other words, by removing formality requirements in the country where protection is claimed, the provision enabled authors to automatically receive protection without needing to satisfy foreign formalities. This matters because while countries can impose conditions on their own nationals, it’s generally assumed that they will not treat their own authors worse than foreign ones. The post follows this presumption: if a country cannot burden foreign authors, it’s unlikely to impose stricter terms on its own people. Although the removal of formalities had been discussed in the international copyright law context as early as the 1858 Brussels Conference, an important event in the development of international copyright law, it was not implemented until 1908. This change addressed practical difficulties, including identifying the “country of origin” when a work was published in multiple countries, and the challenges courts faced in enforcing rights without formalities. (See International Bureau’s Monthly Magazine, January 1910) Tellingly, while a country can make formalities for its people, it cannot do so for foreign authors. It’s generally assumed that a country would not obligate its authors more than it does to foreign authors. Textual Tensions of Article 5(2) While the phrase “any formality” in the first line of the provision might suggest that all kinds of formalities—including de facto ones like opt-out mechanisms—are prohibited, that is arguably not the case. We say this because the provision is divided into two parts, and the prohibition on formalities applies only to the first part, which is germane to enjoying and exercising rights. The second part of the provision, beginning with “Consequently”, gives leeway to the states wherein they can make formalities regarding the ‘extent of protection’
