The EU has launched unprecedented disciplinary measures against Poland, saying its planned judicial reforms threaten the rule of law.
It said 13 new laws have allowed the government to “interfere significantly” in the judiciary.
Poland has been given three months to address the concerns.
But the Polish conservative government said the decision was “political”. It has said the reforms are needed to curb inefficiency and corruption.
Thousands of people across the country have held protests against the planned reforms.
The disciplinary measures, called Article 7, could lead to the suspension of Poland’s voting rights at EU summits, but Hungary has said it would block such a move, that requires the approval of all member states.
