Poland's Constitutional Tribunal is due to weigh in Wednesday on a legal crisis that has upended politics in the country and brought sharp condemnation from European and U.S. authorities.

The highest legislative court, whose role is to judge the constitutionality of laws, will issue a ruling Wednesday on amendments passed in December that fundamentally change how the court functions.

Critics say that the changes have paralyzed the court, effectively preventing it from acting on a check on the power of the conservative ruling Law and Justice party.

The judgment is unlikely to end the ongoing crisis. The government of Prime Minister Beata Szydlo has said it will not accept the court's ruling as legitimate.

The nation is deeply divided between supporters and critics of the government.
