The first amendment to the Cascadian Constitution was approved by the Cascadian Senate on April 21, 2008. The first amendment established formally the Provisional Government, and its limits, powers, and duties. This is to prevent a small legislature to vote on declarations of war, MADP blocs, treaty cancellations, etc. until either the Central Executive Committee nulls it or at the end of the first elections. This is the only time that veto rights over the Senate was given by the Cascadian Constitution.
