Catalan declaration of independence
The Catalan declaration of independence (; ) was a resolution that was passed by the Parliament of Catalonia on 27 October 2017, which declared the independence of Catalonia from Spain and the founding of an independent Catalan Republic. The Act was immediately suspended by the Parliament. The declaration did not receive recognition from the international community. The declaration and proceeding vote were declared illegal as it was done on a simple majority and not the two-thirds requirement of the Catalan constitution.
2017–18 Spanish constitutional crisis
On 11 October, after an extraordinary cabinet meeting intended to address the events on the previous day, Prime Minister Mariano Rajoy announced he was formally requiring the Catalan government to confirm whether it had declared independence before 16 October at 10am, with a further 3-day deadline until 19 October to revoke all deemed illegal acts if an affirmative answer—or no answer at all—was obtained. This requirement was a formal requisite needed to trigger article 155 of the Spanish Constitution, a so-called "nuclear option" that would allow the Spanish government to suspend Catalonia's political autonomy and impose direct rule from Madrid. Pressure mounted within the pro-independence coalition as the CUP demanded an unambiguous affirmation of Catalan independence, threatening to withdraw its parliamentary support from Puigdemont's government if he rescinded his independence claim. In his formal response to Rajoy's requirement hurrying the initial five-day deadline, Puigdemont failed to clarify whether independence had been declared and instead called for negotiations over the following two months. The Spanish government replied that this was not a valid response to its requirement and doubted that Puigdemont's offer for dialogue was sincere due to his lack of "clarity". The refusal from the Catalan government to either confirm or deny independence triggered a second deadline for them to backtrack before direct rule was imposed. The Spanish government subsequently offered to abort the incoming move to suspend self-rule if the Catalan government called for a regional election, but this was ruled out by the latter.
