State legislative sessions in 2026 have featured a number of bills affecting the administrative state, with five Republican trifecta states and one state with a divided government enacting bills that reduce the power of state agencies. The term administrative state refers to executive branch agencies with unelected officials (in this case, at the state level) that have the authority to create, interpret, and enforce regulations.
In 2026, major bills affecting the administrative state included REINS-style bills (which require legislative approval for new agency rules exceeding a specified cost threshold) enacted in one state and passed in another, and bills restricting judicial deference by state courts enacted in two states and passed in another. The 2026 session also saw bills enacted that limit agency power to make temporary rules, require legislative review of new rules, and modify existing REINS-style provisions. Five REINS-style bills and five bills restricting state judicial deference were enacted in 2025.
Bills enacted
Kansas’s HB 2183: Gov. Laura Kelly (D) signed it on Feb. 6. This bill restricted judicial deference in state courts. HB 2183 requires courts to use a de novo standard of review when determining the meaning of language in a state statute, regulation, or other document, rather than deferring to the interpretation of a state agency. The Kansas Senate passed the bill 30-10 on March 27, 2025, and the Kansas House of Representatives passed it 83-39 on Jan. 22, 2026. Kansas has a divided government.
South Dakota’s SB 133: Gov. Larry Rhoden (R) signed it on March 12. This bill established a REINS-style requirement for agency rulemaking, under which major proposed rules (defined as expected to cost "businesses, individuals, other nongovernmental entities, and units of local government" $3 million or more over two years) must receive legislative approval before going into effect. The bill also established a de novo review standard for state courts hearing disputes about whether a proposed rule counts as major. The South Dakota Senate passed the bill 33-0 on Feb. 24, and the South Dakota House of Representatives passed it 66-1 on March 3. South Dakota is a Republican trifecta state.
Idaho’s H 539: Gov. Brad Little (R) signed it on March 17. This bill modified requirements for temporary agency rules, which are exempted from existing statutory language that requires new rules to be approved by the Legislature. The bill specified requirements for agencies to promulgate temporary rules, including a requirement that specific emergency conditions must be met before an agency may re-adopt an expired temporary rule. The Idaho House of Representatives passed the bill 67-2 on Feb. 17, and the Idaho Senate passed it 33-1 on March 10. Idaho is a Republican trifecta state.
Alabama’s SB 167: Gov. Kay Ivey (R) signed it on March 31. This bill restricted judicial deference in state courts, requiring courts to use a de novo standard of review when determining the meaning of statutory or regulatory language, rather than deferring to the interpretation of a state agency. The Alabama Senate passed it 34-0 on Feb. 5, and the Alabama House of Representatives passed it 105-0 on March 17. Alabama is a Republican trifecta state.
Mississippi’s HB 925: Gov. Tate Reeves (R) signed it on April 8. This bill required the Joint Legislative Committee on Performance Evaluation and Expenditure Review (PEER Committee) to review newly adopted agency rules and to report its findings to the Legislature. The bill also created a State Board of Health Professions, with a mandate to advise the Governor and Legislature on health-related professional regulation. The Mississippi House of Representatives passed it 119-1 on Feb. 5, and the Mississippi Senate passed the amended version 50-2 on March 10. The state House passed a conference committee version of the bill 116-0 on March 31, and the state Senate passed it 52-0 on April 1. Mississippi is a Republican trifecta state.
Oklahoma’s HB 4319: Gov. Kevin Stitt (R) signed it on April 17. This bill restricts agency rulemaking to instances in which “the agency has been specifically and explicitly granted rulemaking authority by state law,” and specifically denies that general statutory language like the phrase "as necessary and proper" confers this authority. The bill also requires that legislative review of proposed agency rules (required under the REINS-style law enacted in 2025) include a determination that the agency acted under specific statutory authority. The Oklahoma House of Representatives passed the bill 89-0 on March 11, and the Oklahoma Senate passed it 46-0 on April 15. Oklahoma is a Republican trifecta state.
Vetoed and veto overridden
Wisconsin’s SB289: Gov. Tony Evers (D) vetoed the bill on March 20. This bill would have required agencies to offset the expected costs of new rules to businesses, local governmental units, and individuals with a separate rule reducing expected costs. The Wisconsin Senate passed the bill 18-15 on Feb. 11, and the Wisconsin Assembly passed it 53-45 on Feb. 12. Wisconsin has a divided government.
Wisconsin’s SB277: Evers vetoed the bill on March 20. This bill would have introduced a seven-year sunset provision for agency rules, requiring that rules automatically expire seven years after being promulgated unless they are reissued through the agency rulemaking process. The Wisconsin Senate passed the bill 18-15 on Feb. 11, and the Wisconsin Assembly passed it 53-45 on Feb. 12.
Wisconsin’s SB276: Evers vetoed the bill on March 20. This bill would have required that a plaintiff successfully challenging the validity of an agency rule in court receive attorney fees and costs. The Wisconsin Senate passed the bill 18-15 on Feb. 11, and the Wisconsin Assembly passed it 53-45 on Feb. 12.
Wisconsin’s SB275: Evers vetoed the bill on March 20. This bill would have required that agency statements of scope (which are required by existing state law as a preliminary step in agency rulemaking) would expire after 30 months, and that agencies specify whether a statement of scope is beginning the permanent or emergency rulemaking process. The Wisconsin Senate passed the bill 18-15 on Feb. 11, and the Wisconsin Assembly passed it 53-45 on Feb. 12.
Kansas’ HB2719: Gov. Laura Kelly (D) vetoed this bill on April 6, and the Kansas Legislature overrode it on April 9. This bill created exemptions from existing statutory language that requires various formal procedures, including ratification by the Legislature, as part of agency rulemaking. The bill exempted technical amendments to agency rules and specific categories of rules issued by the Department of Corrections. The bill also added a requirement that agencies submit proposed rules to the legislative Joint Committee on Administrative Rules and Regulations. The Kansas Senate passed the bill 40-0 on March 19, and the Kansas House of Representatives passed it 122-0 on March 24. Kelly’s April 6 veto was overridden by the House 89-34 and by the Senate 38-1 on April 9. Kansas has a divided government.
Passed, not signed
Tennessee’s HB1913: If Gov. Bill Lee (R) signs this bill, it would require rulemaking agencies to publish the text of proposed rules, to “make a good faith effort to notify each trade association or organization” potentially affected by the rule, and for the agency to create a fiscal impact statement based on feedback received. The bill would also introduce a REINS-style requirement, with rules expected to cost $1 million or more over five years (or one year for emergency rules), requiring legislative approval to go into effect. The Tennessee House of Representatives passed the bill 76-16 on April 13, and the Tennessee Senate passed it 24-4 on April 16. Tennessee is a Republican trifecta state.
Georgia’s HB 1247: If Gov. Brian Kemp (R) signs this bill, it would restrict judicial deference in state courts, requiring courts to use a de novo standard of review when determining the meaning of constitutional, statutory, or regulatory language, rather than deferring to the interpretation of a state agency. The bill would also require rulemaking agencies to submit an economic impact statement to the Legislature when promulgating new rules, and to report the economic impact of existing rules to the Office of Planning and Budget every five years (with specified exceptions). The Georgia House of Representatives passed the bill 98-63 on March 4, and the Georgia Senate passed the amended version 48-2 on March 25. The state House passed the Senate-amended version with amendments of its own 98-70 on April 2, and the state Senate passed the amended bill 34-18 on April 3. Georgia is a Republican trifecta state.
