Massachusetts

Since Massachusetts employs an indirect initiative process, the General Court has an opportunity to adopt proposed laws and amendments before they move to a popular vote. However, unlike other states, Massachusetts requires additional signatures following legislative inaction.

For an amendment or statute, signatures must equal 3% of votes cast for governor in the most recent election (excluding blanks). If the legislature declines to act on a proposed statute, supporters are required to collect a second round of signatures totaling 0.5% of the votes cast for governor in the most recent election (excluding blanks). For proposed amendments, one-quarter of the legislature must approve the petition in a joint session -- a second round of signatures is not required.

For a veto referendum, signatures must equal 1.5% of the total votes cast for governor in the most recent election. No more than one-fourth of these certified signatures may come from any one county. If the petitioners request suspension of the law in writing, signatures are required totaling 2% of the total votes cast for governor in the last election.

Missouri

The signature requirement total is based on the number of votes cast for governor in the state's most recent gubernatorial election. In 2/3 of Missouri's congressional districts, proponents must collect signatures equal to 5% of the gubernatorial vote for initiated statutes and 8% of the gubernatorial vote for constitutional amendments. Thus, the total number of signatures required will be less than 5% (or 8%) of the total votes cast for governor.

Until the next gubernatorial election, the minimum number of signatures required (counting the six lowest voting districts) is 146,907 for amendments and 91,818 for statutes.

North Dakota

Since North Dakota does not have a voter registration system, the number of signatures required is tied to the population reported by the last decennial census. As such, any US Citizen who is at least 18 years old and who has resided in the state for at least thirty day may sign an initiative petition. For statutes and veto referenda, the number of signatures required is 2% of the population. For amendments, it is 4% of the population. For recall, signatures must equal 25% of the votes cast for that particular office in the last election. Officials in Congress are exempt.

Ohio

For constitutional amendments, petitioners must submit signatures equal to 10% of the votes cast for governor in the most recent election.

For statutes, signatures equaling 3% of these votes must be submitted in order to place the proposal before the Ohio State Legislature. If the legislature fails to enact the proposed legislation, additional signatures equaling 3% of the last gubernatorial vote must be collected in order to place the measure the ballot. Put simply, if initiative sponsors believe that the legislature will not enact their proposed law, they should plan to collect signatures equaling 6% of the last gubernatorial vote.

Veto referendums also require 6%. In addition, every type of measure requires 1000 preliminary signatures with the initial filing.

Oklahoma

The number of signatures required is tied to the total vote cast for governor in the last gubernatorial election. Amendments, statutes, and veto referendums must receive signatures equaling 15%, 8%, and 5% of this vote, respectively. Previously rejected measures require 25% of this vote in order to be placed on the ballot again within 3 years. Signatures are presumed valid unless challenged.

The basis of the Oklahoma signature requirement used to be the votes cast for the office receiving the most votes in the state's last general election. Due to higher turnout for presidential elections, the signature requirement varied widely every fourth year. In 2010, voters passed Oklahoma State Question 750 amending the requirement.

Wyoming

The signature requirement in Wyoming is based on the number of votes cast in the state's most recent general election--held every two years. However, in most I&R states, the number of signatures required is based on gubernatorial elections--almost always held every four years. As a result of Wyoming's atypical system, the number of signatures changes significantly every two years due to the fact that voter turnout for presidential elections is generally much higher than in mid-term elections.

More specifically, initiated state statutes and veto referendums require signatures equal to 15% of the total ballots cast in the previous general election. This is the highest signature requirement of any state, even considering requirements for initiating constitutional amendments. Citizen-initiated amendments are not allowed in Wyoming.
