BRUSSELS (Reuters) - The European Union’s executive called on Poland on Wednesday to put on hold judicial reforms it said would “have a very significant negative impact” on courts’ independence, or face disciplinary action as early as next week.

The European Commission’s First Vice-President Frans Timmermans also told a briefing: “These laws considerably increase the systemic threats to the rule of law.”

“Collectively, they would abolish any remaining judicial independence and put the judiciary under full political control of the government.”

He was speaking after a tumultuous session in the Polish parliament on Tuesday that saw the nationalist-minded government pushing a law giving it more direct control over the Supreme Court, whose tasks include validating elections in the EU’s largest ex-communist state.
