with the approval of all ministers and the Senate may consult the people on matters of national importance (article 104), that governors and mayors may likewise consult voters on issues falling under their jurisdiction (article 105) and detail the different forms of political participation at a local level (article 106). Chapters II and III: Political Parties and Movements, and Status of the Opposition The second and third chapters of the title concerns political parties and movements, and establishes special protection for opposition parties. The right of all citizens to establish, organize and develop parties and movements as well as their freedom to join or leave them is guaranteed. Political parties and movements are democratically organized with transparency, objectivity, morality, gender equality and the duty to present and disseminate their political programs as their guiding principles.
