(Bloomberg) -- Apple Inc. lost its court fight over a €13 billion ($14.4 billion) Irish tax bill and Google lost its challenge over a €2.4 billion fine for abusing its market power, in a double boost to the European Union’s crackdown on Big Tech.

The EU’s Court of Justice in Luxembourg backed a landmark 2016 decision that Ireland broke state-aid law by giving Apple an unfair advantage. In another victory for the EU’s antitrust chief Margrethe Vestager, the same court ruled that Google illegally leveraged its search-engine dominance to give a higher ranking to its own product listings.

Vestager — who is just weeks away from departing the Brussels-based European Commission after two terms — made Apple and Alphabet Inc.’s Google top targets after taking up her role in 2014. The Apple decision was by far the biggest in her decade-long campaign for tax fairness, which has also targeted the likes of Amazon.com Inc. and carmaker Stellantis NV’s Fiat. Vestager has argued that selective tax benefits to big firms are illegal state aid that are banned in the EU.

“It’s important to show European taxpayers that once in a while, tax justice can be done,” Vestager told reporters in Brussels in response to questions on her Apple win.

Apple’s Chief Executive Officer Tim Cook previously blasted as “total political crap” the EU’s 2016 move to order the firm to pay €13 billion in back taxes, while the commission’s 2017 fine against Google was leveled for abusing its search dominance to give a higher ranking to its own product listings. Vestager ordered Ireland to claw back the sum, which amounts to about two quarters of Mac sales globally. The money has been sitting in an escrow account pending a final ruling. Ireland must now decide what to do with its unwanted windfall.

“We are disappointed with today’s decision as previously the general court reviewed the facts and categorically annulled this case,” an Apple spokesperson said. The company expects to record a one-time income tax charge of about $10 billion in the fiscal fourth quarter ending Sept. 28 as a result of the ruling, increasing its effective tax rate for the period.

Apple shares were down 0.9% at $218.95 in premarket trading at about 9:15 a.m. New York time.
