  Congressional & Legislative

  Primary Authority: Congressional and legislative maps are drawn and adopted by the Montana Districting and Apportionment Commission, a 5-member, politically appointed body. The Montana Legislature has an opportunity to provide recommendations regarding the Commission’s legislative plan, which the Commission is free to adopt or reject.

  • Members: The majority and minority leaders of the Montana Senate and House each appoint 1 commissioner. The initial 4 commissioners then select the 5th commissioner who serves as the presiding officer. If the initial 4 commissioners fail to select a 5th commissioner by their deadline, the Montana Supreme Court appoints the 5th commissioner by majority vote. [Mont Const. art. V, § 14; Mont. Code Ann. §§ 5-1-101, 5-1-102]
  • Timing: The initial 4 commissioners must be appointed during the legislative session preceding each decennial census. Within 20 days of the initial 4 commissioners’ appointment, they must select the 5th commissioner. [Mont. Const. art. V, § 14; Mont. Code Ann. §§ 5-1-101, 5-1-102]
  • Eligibility: Commissioners must be citizens and may not be public officials. Commissioners are prohibited from running for a legislative seat for 2 years after a redistricting plan which they helped create becomes effective. [Mont. Const. art. V, § 14; Mont. Code Ann. §§ 5-1-101, 5-1-105]
  • Voting: Not specified.
  • Public Input & Transparency: At least 1 public hearing must be held on a congressional plan before adopting and filing it as final. At least 1 public hearing must be held on a legislative plan prior to submitting it to the Legislature. The Commission is free to hold additional hearings as it deems necessary. [Mont. Code Ann. § 5-1-108]

  Mapping Timeline: The Commission must hold at least 1 public hearing on a congressional plan before adopting it as final and must file its final adopted congressional plan with the Secretary of State within 90 days of decennial census data becoming available. The Commission must hold at least 1 public hearing on a legislative plan prior to submitting it to the Legislature and it must be submitted by the 10th legislative day of the 1st regular session after the Commission’s appointment or after decennial census data is available. The Legislature must return the plan with its recommendations to the Commission within 30 days of its submission, and the Commission then has 30 days to adopt and file its final legislative plan with the Secretary of State. [Mont. Const. art. V, § 14; Mont. Code Ann. §§ 5-1-108, 5-1-109, 5-1-110, 5-1-111]

All other initiatives and veto referendums require 5% of the qualified electors of the state, including at least 5% of the qualified electors in each of at least 1/3 of the state’s legislative districts. Qualified electors is determined by the number of votes cast for gubernatorial office in the preceding general election in Montana. 603,587 people voted for a gubernatorial candidate in the 2020 election, so 60,359 are required for constitutional amendments and 30,180 for any other initiatives and veto referendums.
