Google has filed an appeal against a European Union regulatory order mandating the sharing of its search data with competitors. The tech giant argues that compliance would cause irreversible harm to its operations and business model.

The legal challenge targets a specific directive from EU regulators aimed at increasing competition in the digital advertising and search sectors. Google contends that the forced data-sharing mechanism undermines proprietary algorithms and user privacy standards.

Legal challenge details

The appeal was lodged in September 2026, following the initial ruling by EU authorities. Key aspects of the dispute include:

• Regulatory mandate: The EU order requires Google to provide rival search engines with access to specific datasets.
• Company stance: Google warns that complying with the order would degrade service quality and violate existing privacy commitments.
• Potential impact: The company states that the operational changes required are not feasible without significant, permanent damage to its core services.

Alphabet Inc.'s Google (NASDAQ: GOOG) (NASDAQ: GOOGL) has been fined €403 million ($463 million) by Ireland's Data Protection Commission (DPC). The penalty stems from allegations that the company coerced users into enabling continuous mobile phone tracking without transparent consent.

The DPC concluded that users were not adequately informed that their location data was being processed for targeted advertising or to derive insights into health conditions, religious beliefs, and political affiliations. The investigation focused on features including Location History, Web & App Activity, and Location Accuracy.

Investigation Background

The probe began six years ago following complaints from multiple European consumer organizations and a 2018 study by the Norwegian consumer agency, Forbrukerrådet. The study highlighted how location data could reveal sensitive personal information.

The European Consumer Organization (BEUC) lodged a complaint alleging that Google employed "various tricks" to ensure users' location history and activity settings remained enabled. The regulator found that Google failed to process this data lawfully or transparently.

Regulatory Response

Google stated that the case concerns outdated policies, noting significant changes to its practices since 2019. The company highlighted the introduction of new tools designed to simplify location-data management for users.

Broader Legal Pressure

This penalty coincides with intensified regulatory scrutiny of Google in Europe. In July, the European Commission imposed a combined fine of €890 million ($1 billion) for two Digital Markets Act (DMA) violations:

• €460 million for self-preferencing its services in Google Search.
• €430 million for restricting businesses from directing users to alternative purchase channels outside Google Play.

The Commission found that Google breached the DMA by giving its own shopping, hotel, transport, and sports services greater prominence than third-party competitors through enhanced placement and visuals.

Potential Damages

Legal experts suggest the ruling could encourage further lawsuits, with rivals seeking damages for both recent DMA violations and earlier antitrust conduct. Potential damages could reach $10 billion. Companies including Foundem, Kelkoo, and Moltiply Group are already pursuing multibillion-dollar claims related to Google's search practices.

In the United States, a federal judge ordered Google to alter its online advertising practices and appoint an antitrust compliance monitor. While the court rejected the Department of Justice's request to break up the ad tech business, Google must open AdX bidding data to rivals and stop requiring publishers to use AdX alongside its ad server for six years. Google plans to appeal the ruling regarding its Ad Manager business.
