Members of Catalonia's regional government who were removed are appearing in the High Court in Spain today (November 2).
Nine members attended, accused of sedition and rebellion following the region's attempt to hold an independence referendum branded illegal by the government, according to the BBC.
However the region's leader Carles Puigdemont did not attend, along with four others who are in Belguim.
The members of the Catalan regional government have not yet been charged, but if they are and are found guilty they could face a maximum of a 30-year jail sentence for rebellion.
The chief prosecutor in Spain has called for eight of the group to be arrested.
An investigation is to take place which could mean members going on trial, a judge will then decide whether members should be sent to prison.
Those who attended court today (November 2) included the former deputy leader Oriol Junqueras, foreign affairs chief Raul Romeva, interior minister Joaquin Forn and spokesperson Jordi Turull.
Puigdemont is currently in Belguim and claims he will not travel back to Spain unless the ministers are ensured a fair trial. He also told Reuters the reason he did not go to court is because "the climate is not good."
There are also six other members of the dissolved Catalan parliament who are also facing charges however they will be called to the Supreme Court on November 9 due to parliamentary immunity.
Spanish Prime Minister Mariano Rajoy has called a snap election for the region to be held in December, after taking direct rule over Catalonia, following its attempt to declare independence.
