Google is filing an appeal at the European Union’s top court against an earlier decision to uphold a $2.8 billion antitrust fine.
The penalty was imposed in January by the European Union, which accused Google of unfairly promoting its service in search results to favour its own comparison service.
Google said in its appeal that the EU’s ruling was a “disproportionate” punishment that “exceeds the limits of the European Union’s remit”.
The EU’s decision came as Google’s parent company is facing a widening array of antitrust investigations across Europe.
The U.S. Department of Justice last week announced an antitrust investigation into Google’s search advertising business, while the EU is investigating its Android smartphone business.
A spokesman for the EU’s competition watchdog declined to comment.
The EU decision in January was the latest in a series of setbacks for Google, which has been at the heart of a long-running campaign by European regulators to impose tougher rules on technology companies.
