• The European Union's second-highest court on Wednesday said a 1.5 billion euro ($1.67 billion) antitrust fine imposed on Google by regulators should be annulled.
• The case stems from 2019 when the European Commission, the EU's executive arm, said Google had abused its market dominance in relation to a product called AdSense for Search.

The European Union's second-highest court on Wednesday said a 1.5 billion euro ($1.7 billion) fine imposed on Google by regulators should be annulled, siding with the U.S. tech giant after it challenged the ruling.

The case stems from 2019 when the European Commission, the EU's executive arm, said Alphabet owned Google had abused its market dominance in relation to a product called AdSense for Search. This product allowed website owners to deliver ads into the search results on their own pages.

Google acts as an intermediary allowing advertisers to serve ads via search on third-party websites.

But the commission alleged that Google abused its market dominance by imposing a number of restrictive clauses in contracts with third-party websites, which ultimately prevented rivals from placing their search ads on these websites.

The commission fined Google 1.49 billion euros at the time. Google appealed, sending the case to the EU's General Court.

The General Court said Wednesday that it "upholds the majority of the findings" but "annuls the decision by which the Commission imposed a fine of" nearly 1.5 billion euros.

The court added that the commission "failed to take into consideration all the relevant circumstances in its assessment of the duration of the contract clauses" that it had deemed abusive.

A Google spokesperson told CNBC that it would review the full decision closely.

"This case is about a very narrow subset of text-only search ads placed on a limited number of publishers' websites. We made changes to our contracts in 2016 to remove the relevant provisions, even before the Commission's decision. We are pleased that the court has recognized errors in the original decision and annulled the fine," the spokesperson said.

A spokesperson for the commission said it takes note of the judgement and will reflect on the possible next steps.

The commission could appeal this decision which would send it up to European Court of Justice, the EU's top court.

There has been a slew of court cases involving the EU and U.S. tech companies reaching their conclusions recently.

This month, the ECJ upheld a 2.4 billion euro fine imposed on Google for abusing its dominant position by favoring its own shopping comparison service. And the same court ruled that Apple must pay 13 billion euros in back taxes to Ireland, ending a decade-long case.
