Congressional and legislative plans are enacted by the Oklahoma Legislature, subject to the Governor’s veto. If the Legislature fails to enact a legislative plan, authority passes to the Bipartisan Commission on Legislative Apportionment, a 7-member, politically appointed body.
Oklahoma ’s congressional delegation remained at 5 seats following the 2020 reapportionment.
Primary Authority: Congressional plans are drawn and enacted by the Oklahoma Legislature, subject to the Governor’s veto. The Legislature can override a veto with a 2/3 vote in each chamber. Republicans currently have veto-proof majorities in both chambers.
If a bill is presented to the governor during session, the governor has 5 days to sign or veto it; otherwise, it becomes law without signature. If the bill is delivered to the governor during the last 5 days of the session, the governor must sign or veto it within 15 days of session adjournment; otherwise, it is pocket vetoed. Sundays are excluded from these calculations.

Backup Authority: If the Legislature fails to enact legislative plans by its deadline, authority passes to the Bipartisan Commission on Legislative Apportionment, a 7-member, politically appointed body.
Mapping Timeline: The Legislature must enact final legislative plans within 90 legislative days after the convening of the first regular session following the decennial census. If they fail to do so, authority passes to the Bipartisan Commission on Legislative Apportionment, but no deadline for adoption of final plans is specified. [Okla. Const. art. V, § 11A]
Redistricting Criteria:
Map Challenges: Within 60 days of a redistricting plan being enacted by the Legislature or adopted by the backup commission, any qualified elector can challenge its validity by filing a petition with the Supreme Court of Oklahoma. If the Court finds the plan to be invalid, it must remand the plan to the backup commission which must modify it to remedy the issues identified. Additionally, If the backup commission fails to act in a “timely” manner, any qualified elector can petition the Supreme Court of Oklahoma to compel the Commission to act, and the Court must issue its decision within 60 days of the last such petition being filed. [Okla. Const. art. V, §§ 11C – 11E]
Types of Measures: Direct initiatives are permitted to amend statutes and the state constitution, and referendums are permitted to amend statutes. Legislatively initiated ballot measures may amend both statutes and the state constitution.
Single-Subject Rule: Yes.
Initiative Subject Restrictions: A subject cannot appear on an initiative if it has appeared on another initiative in the past 3 years unless they obtain signatures equal to at least 25% of legal voters in the state. Initiatives cannot contain a proposal that the Legislature could not pass themselves lawfully.
Signature Requirements: Constitutional amendments require signatures equal to 15% of all votes cast for gubernatorial candidates in the last general election, 8% for statutory amendments, and 5% for referendums. 1,153,284 people voted for a gubernatorial candidate in the 2022 general election in Oklahoma, so 172,993 are required for constitutional amendments, 92,263 for statutory amendments, and 57,665 for referendums.
Submission Deadlines: Referendum petitions must be submitted 90 days after the adjournment of the legislative session in which the subject law was passed. Initiative petitions must be submitted no later than 90 days after the start of the circulation period as prescribed by the Secretary of State.
Circulation Period: Petitions can be circulated for 90 days. The Secretary of State determines when the 90-day period begins for initiative petitions.
Ballot Title and Summary: The ballot title and summary are proposed by the Secretary of State, subject to approval by the Attorney General. Proponents may suggest a ballot title and submit it to the Secretary of State. Expedited reviews for titles and summaries are permitted.
Other Requirements: A fiscal impact statement is not required. There are no supermajority requirements. The Legislature can repeal a statutory initiative through a majority vote. The Legislature can amend or repeal an amendment by sending it to voters through a majority vote of each chamber of the Legislature. Initiatives are permitted on general, primary, and special election ballots, but not on odd-year ballots.
