Google launched an appeal against 2.4-billion fine imposed by European anti-trust authorities which imposed a fine on the tech giant accusing it of favouring its online shopping centres in search results.
A spokesman for Google confirmed Monday they had filed the appeal but said the company had no further comment to make.
The Luxembourg-based General Court, Europe's second-highest, is expected to take several years before ruling on the appeal.
The fine over Google Shopping broke the previous European Union record for a monopoly case against U.S. chipmaker Intel of 1.06 billion euros in 2009 and made the EU the global leader in regulating Silicon Valley giants.
Margrethe Vestager, the EU's competition commissioner had said that Google's activity was "illegal under European Union antitrust rules".
Initially Google was given 90 days to comply or face further fines.
Intel lost its first appeal, but persisted, and on Wednesday the case was referred back to the court that had rejected it with the instruction to allow Intel to challenge more of the evidence against it.
"Google's strategy for its comparison shopping service wasn't just about attracting customers by making its product better than those of its rivals", commissioner Margrethe Vestager, who is in charge of competition policy, said when June's decision was announced.
