On Tuesday, Ursula von der Leyen told the European Parliament that the European Commission – the EU’s executive – was “carefully assessing this judgement”.
She said: “This ruling calls into question the foundations of the European Union.
“It is a direct challenge to the unity of the European legal order.”
Ms von der Leyen set out three options for the EU to pursue: legally challenging the court ruling, withholding EU funds, or suspending some of Poland’s rights as a member state.
