A popular referendum, depending on jurisdiction also known as a citizens' veto, people's veto, veto referendum, citizen referendum, abrogative referendum, rejective referendum, suspensive referendum, and statute referendum, is a type of a referendum that provides a means by which a petition signed by a certain minimum number of registered voters can force a public vote on an existing statute, constitutional amendment, charter amendment, or ordinance; in its minimal form, it simply obliges the executive or legislative bodies to consider the subject by submitting it to the order of the day.
