Laws governing the initiative process
In the U.S., 26 states provide for a statewide initiative process, referendum process, or both. Washington, D.C. also has an initiative and referendum process. These types of ballot measures are known as citizen-initiated ballot measures.
- The initiative process allows citizens to collect signatures to place a new statute or constitutional amendment on the ballot.
- The referendum process, also called a veto referendum or citizen's veto, allows citizens to collect signatures to ask voters whether to uphold or repeal an enacted law.
Laws governing the initiative process articles explain the process for placing an initiative on the ballot in each state that allows initiative and referendum.
