Catalonia’s secession process will become a significant problem, Prime Minister Mariano Rajoy has said.
Last month, pro-independence parties in the wealthiest region of Spain who support the freedom of Catalonia, submitted a resolution to secede from the rest of the country in the parliament of Barcelona.
Though there is no article that is legally-binding, the text calls for a separate social security system and treasury, with a vision of complete independence until 2017.
"If on Monday (the resolution) is approved... we will immediately go to court," Deputy Prime Minister Soraya Saenz de Santamaria said.
According to her, Prime Minister Rajoy and his ministers will assemble and go to the Constitutional Court within the week.
Last month, the pro-independence parties gained a majority of seats in the 135-seat Catalan parliament in Barcelona, winning 75 seats, for the very first time during its regional parliamentary elections.
However, they failed to win a majority of all votes cast in last month's elections, which has left the central government in Madrid questioning the legitimacy of their latest push for independence.
In recent years, Catalans' longstanding demands for greater autonomy have increased, as the country's economy went into crisis.
The Catalan region is home to 7.5 million people, and is Spain's richest region, having its own widely spoken language and distinct culture.
