WARSAW (Reuters) - Poland may go to the top European Union court to challenge an EU rule of law procedure launched against it earlier this year if Brussels steps up its pressure on Warsaw, the head of the ruling conservative party has said.

The EU launched an unprecedented inquiry in January into whether Poland's new eurosceptic government had breached the EU's democratic standards through its attempted reform of the country's constitutional court.
