So why not have a referendum in Catalunya like in Scotland? The central government’s argument is that there can’t be a referendum because it would be illegal. Why would it be illegal? Because the central government won’t approve it, and the constitution requires their sign-off.
Any why won’t the central government sign-off? Because it says the referendum is illegal… etc
Of course, the Catalans are saying they aren’t having a referendum, they are having a “Consulta”, which according to their own Statut, they are allowed to do (according to article 122):
The Generalitat has exclusive power to establish the legal framework, modalities, procedures, implementation and the call by the Government itself or by local authorities, within the scope of its powers, surveys, public hearings, forums participation and any other instrument of popular consultation, except as provided in Article 149.1.32 of the Constitution.
The constitution says:
The State has exclusive jurisdiction over the authorization to call for popular consultations by route of referendum.
Still, Rajoy shouldn’t act as if he is obligated by law to stop the
referendum consultation, he’s just stopping it because he doesn’t want it to happen.
