A legal battle has erupted between Spain's Constitutional Court (TC) and the Audiencia of Seville over the controversial ERE corruption case.

The TC had annulled convictions against former Andalusian leaders, sparking the Seville court's attempt to seek European Union (EU) intervention.

The TC's progressive majority argues that Spanish law prohibits challenges to its rulings, while conservative judges and judicial associations support the Seville court's right to consult the EU's Court of Justice (TJUE).

Critics claim the TC's move to block this consultation undermines EU law's primacy.

The case highlights tensions between national and European legal frameworks, with implications for judicial independence and anti-corruption efforts.
