Top CJEU Cases Defining Information Society Services: Landmark Rulings and Legal Implications

Information Society Services (ISS) lie at the heart of Europe’s digital economy, covering everything from search engines to marketplaces, video platforms to transport apps. The Court of Justice of the European Union (CJEU) has played a pivotal role in interpreting the scope and limits of ISS under EU law, particularly under Directive 2000/31/EC (E-Commerce Directive) and now within the evolving framework of the Digital Services Act (DSA).

In this article, we unpack four landmark CJEU decisions—Google Spain, Uber, Airbnb, and YouTube—that have shaped how services qualify (or do not qualify) as ISS, with practical implications for digital platforms, regulators, and legal advisors.

1. Google Spain SL and Google Inc. v AEPD and Mario Costeja González (C-131/12)

This 2014 decision is widely known for introducing the “right to be forgotten” under data protection law. But crucially, it also reaffirmed Google Search as an Information Society Service—a classification that triggered the application of both e-Commerce and data protection frameworks.

Key Takeaways

• The CJEU confirmed that a search engine is a provider of ISS, despite being free of charge to users. Its service—indexing and organizing third-party content—was commercial and covered by EU law.
• The Court ruled that Google was a data controller when processing search results related to individuals.

Implications

• The case expanded the concept of “controller” in ISS contexts.
• It also confirmed that intermediary ISS providers can be subject to rights-balancing obligations, such as delisting search results under specific conditions.

2. Uber Spain (Asociación Profesional Elite Taxi v Uber Systems Spain SL) (C-434/15)

The Uber case tackled the hybrid nature of digital platforms—where a digital interface (the Uber app) is used to provide a traditionally regulated service (urban transport).

Key Takeaways

• The CJEU held that Uber was not merely an ISS. Instead, its service formed an integrated part of urban transport, involving control over pricing, quality, and access to drivers.
• Therefore, Uber’s activity fell outside the E-Commerce Directive, and could be regulated at the national level under transport law.

Implications

• Set a precedent for disqualifying digital platforms as ISS if they exert material control over the provision of an underlying physical service.
• Opened the door for national regulation of “platform work” intermediaries.

3. Airbnb Ireland UC v AHTOP (C-390/18)

This case examined whether Airbnb’s online booking platform could be regulated as a real estate agent in France, despite operating across the EU.

Key Takeaways

• The CJEU concluded Airbnb is an Information Society Service, as it acts independently of property owners and does not control or manage the actual rental services.
• Airbnb was not obliged to hold a real estate license under French law, given the harmonized protection offered by the E-Commerce Directive.

Implications

• Reinforced country-of-origin principle protections for platforms offering pure digital intermediation services.
• Drew a clearer boundary between passive digital intermediaries (ISS) and active service providers.

4. YouTube and Cyando (Joined Cases C-682/18 and C-683/18)

These parallel cases assessed the liability of video-sharing platforms (YouTube) and file-hosting services (Uploaded.net) for user-uploaded copyrighted content.

Key Takeaways

• The Court clarified that platforms like YouTube can be ISS providers, and enjoy limited liability as hosts under Article 14 of the E-Commerce Directive—if they do not have actual knowledge of illegal content.
• However, platforms can lose their liability exemption if they actively promote, control, or organize infringing activity.

Implications

• Confirmed the conditional liability shield for ISS under EU law.
• Reinforced the duty to act expeditiously upon notification, while preserving a balance between platform freedom and IP protection.

Conclusion: ISS Definition Continues to Evolve

The CJEU has provided critical clarity and nuance on what constitutes an Information Society Service. These rulings show that:

• The degree of control over the underlying service is decisive in classification.
• The passivity or neutrality of the intermediary affects liability.
• The digital layer alone is not sufficient to qualify a service as an ISS—context matters.

As the Digital Services Act begins to apply, these precedents remain foundational—helping to distinguish between regulated digital platforms and traditional service providers operating online. Legal practitioners must continuously assess new business models against these standards to determine compliance obligations and risk exposure.
