The European Court of Justice has ruled against Apple and Google in separate high-profile cases, marking a significant victory for EU regulators. Apple must pay €13 billion in back taxes to Ireland, concluding a decade-long dispute over alleged unfair tax advantages. In a parallel case, the court upheld a €2.4 billion fine against Google for abusing its market dominance by favoring its own shopping service over competitors. Both rulings solidify the EU's stringent stance on Big Tech and validate the European Commission's approach to regulating market fairness. Margrethe Vestager, the EU's competition chief, hailed the decisions as key wins for tax justice and competitive integrity. Both companies expressed disappointment but acknowledged the rulings.
