As of 16th October 2017, A Spanish judge has jailed two key members of the Catalan independence movement. As the BBC news reports:
Jordi Sánchez and Jordi Cuixart, who lead prominent separatist groups, are being held without bail while they are under investigation for sedition.
Indeed, Jordi Sánchez and Jordi Cuixart are respectively the leaders of Catalan National Assembly (ANC) and Òmnium Cultural, the main organizations supporting the independence of Catalonia.
As the report says:
They are being investigated over a protest on 20 September in which a crowd blocked Civil Guard officers inside a building in Barcelona, Catalonia's regional capital.
For this, the judge has decided to jail them immediately without a bail under the accusation of sedition: Spanish prosecutor seeks sedition charges for leaders of Catalan protests. In this news we can read The crime carries a charge of up to 15 years in prison and it describes the context of the accusation:
At least 40,000 demonstrators descended on the Catalan department of economy as it was raided on Wednesday, blocking agents inside from leaving for up to nine hours until the judge who had ordered the operation made a midnight phone call to the head of the Catalan police.
Just for the sake of context: Human Rights Watch reported Spain: Police Used Excessive Force in Catalonia a few days later.
I found some news (like La sentencia del Supremo que esgrime la Fiscalía condenó por sedición el bloqueo de un desahucio, in Spanish) talking about a case in 1976 where some neighbours from Huesca were accused of this crime, but the sentence was later on reduced.
For this, I wonder: has anybody been found guilty of sedition since the Constitution of Spain was approved in 1978? What was the prison sentence for them?
