MADRID: The speaker of Catalonia's sacked parliament appeared before Spain's Supreme Court on Thursday in the latest legal case brought against separatist leaders for their role in the region's divisive independence bid.
A judge may decide to detain Carme Forcadell and five former lawmakers on charges of sedition, rebellion and misuse of public funds after Catalan lawmakers voted last month to split from Spain.
They are suspected of having followed a "concerted strategy to declare independence", before the official declaration of the Catalan parliament on October 27, deepening Spain's most serious political crisis in decades.
That declaration was annulled Wednesday by Spain's Constitutional Court.
The Catalan crisis has prompted hundreds of businesses to re-register outside the wealthy northeastern region and caused disquiet in a European Union still dealing with Britain's shock decision to leave.
On Wednesday a general strike called in Catalonia by a pro-independence union caused widespread travel chaos, cutting Spain's main highway link to France and the rest of Europe and disrupting trains from Barcelona to Paris, Marseille and Lyon.
Authorities said around 150,000 people were affected.
Despite the blockages, the walkout was however on a far smaller scale than previous strikes in the region.
Encouraged by their charismatic leader Carles Puigdemont, Catalan leaders voted to declare unilateral independence from Spain after going ahead with a banned referendum on October 1.
Separatists said 90 percent of voters opted for independence but critics counter that pro-unity supporters boycotted a plebiscite that violated Spain's constitution.
In response, the government of Prime Minister Mariano Rajoy suspended Catalan autonomy, dismissed its parliament and government, and organised new regional elections for December 21.
A judge in Madrid last week ordered that eight members of Puigdemont's sacked government be detained for their role in the secession drive.
The Supreme Court could also decide to place Forcadell and the former MPs in pre-trial detention.
Outside the court on Thursday a small group of protesters gathered, holding banners against independence and declaring Wednesday's strike action a "total fiasco".
There were also a handful of pro-independence supporters alongside cries of "Jail for Puigdemont!"
Puigdemont and four former ministers are themselves in self-imposed exile in Belgium and are due to appear before a judge next week after Madrid issued a EU-wide warrant for their extradition.
The 54-year-old has ignored a summons to appear before a judge in Madrid, saying he wants guarantees he will receive a fair trial.
His presence in the European capital has raised some fears of stoking communal tensions in Belgium after Flemish separatists in the ruling coalition there spoke out in support of Catalan independence.
Belgian Prime Minister Charles Michel on Wednesday moved to deny that his government was "in crisis" over the saga.
The charges faced by former Catalan leaders carry up to 30 years in jail.
Catalonia, a region of 7.5 million people that accounts for a fifth of Spain's GDP, is deeply divided over independence.
