The Constitution of the Republic of Serbia

There have been many versions of the Constitution in Serbia with the most recent one being made on September 30, 2006. The Constitution can be amended by at least two-thirds of the National Assembly (the name of the parliament in Serbia) after being proposed by at least one-third of the National Assembly, the President of the Republic, or by a petition of at least 150,000 voters.  Some issues also must have a referendum which means that a majority (over 50%) of the people of the country have to vote for it.
