Constitution of Italy
During the first months of 2012 IV activists, while being still members of VS, collected more than 20,000 signatures in support for a referendum on independence. On 22 May they presented the signatures to the President of Veneto, Luca Zaia. Zaia informed the Regional Council and its President Clodovaldo Ruffato asked an opinion to the legal office, which explained that such a referendum was not legal under the Constitution of Italy.
