The General Court of the European Union, based in Luxembourg, dismissed Opera Norway's challenge on 2 September 2026 and upheld the European Commission's decision not to designate Microsoft Edge as a gatekeeper under the Digital Markets Act [Reuters](https://www.reuters.com/world/eu-court-rejects-opera-challenge-against-eu-exemption-microsofts-edge-dma-rules-2026-09-02/). The ruling ends a regulatory dispute over whether Microsoft's browser should face obligations imposed on dominant digital gatekeepers.

## The Challenge and Its Dismissal

Opera Norway, the Norwegian browser maker, had contested the Commission's exemption of Edge from gatekeeper designation. In **Case T-357/24**, Opera argued that Edge should be subject to stricter regulatory oversight under the DMA, which requires large digital platforms to ensure interoperability and fair competition [Euractiv](https://www.euractiv.com/news/microsoft-edge-remains-outside-eus-gatekeeper-rules/). The General Court dismissed the action in its entirety, finding no legal basis for overturning the Commission's judgment.

## Court's Reasoning

The court upheld the Commission's decision by accepting Microsoft's **"sufficiently substantiated arguments to demonstrate that Edge did not constitute an important gateway"** [Curia Europa](https://curia.europa.eu/site/upload/docs/application/pdf/2026-09/cp260113en.pdf). This finding is significant because gatekeeper status under the DMA triggers mandatory compliance with a suite of rules designed to prevent anticompetitive conduct, including data access requirements, self-preferencing restrictions, and interoperability obligations.

The judgment reflects the Commission's approach to the DMA's threshold: while Microsoft was already designated a gatekeeper for its search engine and advertising services, the regulator determined that Edge—despite being bundled with Windows—did not meet the statutory criteria for gatekeeper status in the browser market. The General Court's affirmation means this distinction stands unchallenged.

## Implications for Browser Competition

Opera's loss removes a potential regulatory pathway to impose DMA obligations on Edge. The ruling does not bar Opera from competing or filing complaints through other mechanisms, but it does clarify that browser gatekeeping will not be established through this court challenge. For Microsoft, the outcome confirms that Edge can operate without the compliance overhead required of designated gatekeepers, though the company remains bound by DMA rules in its search and advertising businesses.

The case illustrates how DMA gatekeeping designations are now subject to judicial scrutiny. While the Commission has broad discretion in defining gateways, courts will review whether the underlying factual findings—such as market importance and control over access—are properly substantiated.
