(Bloomberg) -- Polish protest organizers vowed to take to the streets to resume some of the largest anti-government rallies in the nation’s post communist history after the top court clarified a ruling that effectively bans abortion.

The Constitutional Court published a written justification on Wednesday of its October verdict, which tightened what was already one of the European Union’s strictest laws on ending pregnancies.

“See you in front of the Constitutional Tribunal today at 6:30pm,” the Women’s Strike protest group said on Facebook.

According to the court’s 154-page clarification, abortion is admissible if there’s high probability of irreversible or lethal damage to the fetus along with danger to the health or life of the mother, the Interia.pl news website reported.

Poland’s government has been stalling the implementation of the verdict for over three months, an unprecedented move without legal justification, by withholding its publication in the official gazette, which is required for the ruling to come into force.

The court’s October decision triggered an outpouring of public anger in the heavily Catholic country, particularly among women and younger people.
