He was speaking a day after Polish President Andrzej Duda said he would veto two government-backed bills to overhaul the country’s courts, amid a political storm over the judiciary.
The commission is on Wednesday set to consider the court reforms in Poland and decide on any further steps.
The commission last week said it was ready to take action against Poland for violating EU laws, warning that a planned overhaul of the country's judicial system -- which has sparked over a week of street protests across Poland -- threatens the independence of courts.
Commission spokesman Margaritis Schinas has said the EU’s executive arm will take into account Duda’s veto decision when it meets on Wednesday.
Caution urged
Waszczykowski told public broadcaster Polish Radio that the European Commission should be cautious in considering any action against Warsaw.
"I hope that tomorrow the commission will only note that the legislative process has been halted or postponed, and will not undertake any... discussion and much less [adopt] any position," he said.
Earlier this week, Waszczykowski told politicians in Berlin “not to interfere" after Germany’s justice minister warned Warsaw could face political isolation over its controversial court reforms.
Poland's ruling conservative Law and Justice (PiS) party has said sweeping changes are needed to reform an inefficient and sometimes corrupt judicial system, accusing judges of being an elite, self-serving clique often out of touch with the problems of ordinary citizens.
But President Duda, who hails from Law and Justice, said on Monday he would veto government-backed bills to reform the Supreme Court and a powerful judges' ethics council.
'Division in society'
Voicing concern over social unrest, Duda said: “I do not want this situation to deepen, because it deepens division in society.”
However, Duda did sign into law a third bill that changes the way the heads of district and appeals courts are appointed and dismissed, giving more power to the justice minister.
Duda said that “wise” changes to the judiciary were needed, and announced that he would himself draw up new bills on the Supreme Court and the influential National Council of the Judiciary (KRS), a body tasked with safeguarding the independence of courts and judges.
