Competition analysis: The EU’s highest court has rejected Google’s latest appeal in the Google Shopping proceedings, upholding the European Commission’s findings of abuse of dominance and resulting €2.42bn fine. The Court of Justice re-affirmed the Commission’s decision that Google has violated Article 102 of the Treaty of the Functioning of the European Union (TFEU) by engaging in ‘self-preferencing’ practices that favoured its own comparison shopping service on its general search engine results pages and demoted results from competing services. The judgment of 10 September 2024 confirms that self-preferencing practices can amount to a standalone abuse of dominance, strengthening the Commission’s discretion to incorporate novel theories of harm in this area, particularly in cases that concern access restrictions. It will likely embolden the Commission to consider new enforcement actions, with particular significance to firms that operate in the tech sector.
