Section 2 of the constitution continues “it recognizes and guarantees the right to self-government of the nationalities and regions of which it is composed and the solidarity among them all.” 1 However it is not the constitution that is the problem blocking a referendum; rather it is the Spanish parliament. The government and parliament clearly could ask the King to allow a referendum on Catalan independence if it so wished. It should do so in order to prevent any more existential challenges to the constitution; constitutions have to be flexible if they are to survive the government is therefore wrong to treat it as a static unchanging document and justification for ruling out a referendum for Catalan independence. 2  1 Cortes Generales, Spanish Constitution, 27 December 1978,  Section 2  2 Guibernau, Montserrat, ‘Calls for independence in Catalonia are part of an evolution of Spain’s democracy that the country’s constitution may have to come to accommodate.’, London School of Economics and Political Science, European Politics and Policy, 8 October 2012,
