Status verified as of 14 September 2026. Political positions change; this explainer describes the documented position on that date.

Current constitutional position

Catalonia is an autonomous community of Spain under its 2006 Statute, which describes it as a nationality.[1] The Spanish Constitution rests on the indissoluble unity of the Spanish Nation, and referendums require State authorisation.[2][3]

The 2017 referendum law was declared void and the Parliament’s declaration resolutions were suspended.[4][5] The amnesty law of 2024 has been largely upheld by the Constitutional Court and found compatible with EU law.[6][7]

As of September 2026 its application to members of the 2017 government on misuse-of-funds charges, including Carles Puigdemont, depended on pending Constitutional Court rulings.[8]

Politics and opinion

The president of the Generalitat since August 2024 is Salvador Illa of the PSC.[9] A July 2026 survey by the Centre d’Estudis d’Opinió found 45% for independence and 51% against.[10] Independence organisations called demonstrations for 11 September 2026.[11]
