Google has lodged its appeal to the EU's Luxembourg-based European Court of Justice over the €2.4 billion fine imposed on it by the European Commission Competition Directorate for favouring its shopping service in search results.
The EU's competition commission had ruled that Google abused its dominant position to favor its own shopping comparison service in internet searches, ordering the company to stop the practice by September 28.
A Google spokeswoman declined to comment.
Initially Google was given 90 days to comply or face further fines.
Another spokesperson said the European Union competition enforcer will defend its decision in court.
The Commission is reviewing its Google Shopping decision in light of the ECJ's Intel ruling, according to Reuters.
Google has made a decision to appeal the record-breaking fine imposed on it by the European Union's highest antitrust authority in July.
The fine handed to Google was a significant hike on the previous record penalty of €1.06bn (£937m) dished out by the commission to USA microchip firm Intel in 2009.
It took Intel the best part of eight years to obtain Wednesday's judgement, and the case isn't over yet, so Google is likely have a long legal battle ahead of it. It denied other companies the chance to compete on the merits and to innovate.
"Instead, Google abused its market dominance as a search engine by promoting its own comparison shopping service in its search results, and demoting those of competitors", she said.
European regulators are also expected to levy further fines in separate cases over Google's Android smartphone software and its AdSense advertising business as early as next month.
