Google asks the EU’s General Court to overturn competition orders that require the company to open parts of its search business to rivals, according to reporting across outlets.

The dispute centers on obligations tied to the EU’s finding that Google holds a dominant position in online search and related services. The EU requires Google to make changes that allow competing providers to reach users more easily, including measures related to how search results and visibility are presented, and how access to certain services is structured.

Outlets describe the challenge as a test of how far the EU can go in ordering structural and technical changes, including those intended to improve competition in the search market. Google argues that the remedies are unlawful and/or disproportionate, while the EU position—reflected in the underlying orders—is that the steps are necessary to address anti-competitive conduct and promote fair access for competitors. The case is expected to proceed through the EU court system.
