Term-Limit Comparator
Go beyond the term-limit numbers. Explore the governing rules for service, departure, and renewed eligibility.
Version 2.01 — October 28, 2026
Comparing term-limit systems begins with identifying the provisions that govern each office. Published descriptions sometimes differ from controlling legal text. Transition rules, administrative or judicial interpretation, and subsequent amendments can affect how an eligibility boundary operates.
Rotation Research's Term-Limit Comparator assembles governing eligibility classifications, legal sources, and office-specific qualifications. Researchers can compare up to four existing systems or hypothetical designs, examining eligibility boundaries, their consequences, and the conditions under which eligibility returns.
The Comparator also provides numerical illustrations where the governing rules support them. These describe legally permitted service sequences, distinct from actual officeholding.
Start Here — Using the Comparator
1. Choose systems to compare. Select an existing jurisdiction and office, or create a hypothetical system. Begin with A alone; add B, C, and D as needed. Each selection preserves the governing eligibility architecture and its applicable qualifications.
2. Examine the governing rules. Compare eligibility architecture, eligibility boundary, consequence at the boundary, and restoration condition. Expanded results provide additional counting rules, transition provisions, and office-specific details.
3. Examine temporal illustrations. The One-Return share describes permitted service across a first stint, required interruption, and second stint. A recurring-cycle reference is also provided where applicable. Numerical illustrations are qualified or withheld when governing inputs do not support them.
4. Review sources and share comparisons. Expand Legal Provenance to examine governing authorities and supporting sources. Use Copy Comparison Summary or Copy Comparison Link to preserve or share the comparison. Independently verify current law when operative legal status is material.
Try a Documented Comparison — California and Arizona
Open the California–Arizona comparison to compare California Legislature — Proposition 28 cohort (A) with Arizona Legislature (B).
California's Proposition 28 cohort operates under a twelve-year lifetime eligibility boundary aggregated across both legislative chambers. Arizona permits four consecutive two-year terms in either chamber, followed by restoration after one full term outside the affected chamber.
Examine the eligibility boundary, consequence at the boundary, and restoration condition for each system. Arizona's counting provisions treat any portion of a legislative term as a complete term, and its transition rule counts terms beginning on or after January 1, 1993.
The comparison shows how similarly situated legislative offices can operate under different rules for required departure, future eligibility, and movement between chambers.

Interpreting Comparator Results
The Comparator identifies the governing eligibility architecture for each selected office and the conditions that determine continued service, required departure, and future eligibility.
Four dimensions organize the comparison: eligibility architecture, eligibility boundary, consequence at the boundary, and restoration condition.
Where governing rules support numerical illustrations, the Comparator presents a finite One-Return share and, where applicable, a recurring-cycle reference. These describe legally permitted service under the specified assumptions. Actual officeholding depends on elections, individual decisions, and subsequent governing developments.
Office-specific qualifications identify unresolved legal questions or limitations on modeled calculations. Verified governing provisions remain available even when a dependent numerical illustration is withheld.
Historical and Methodological Context
The Comparator draws on Rotation Research's study of the changing relationship among service, interruption, restoration, and renewed eligibility.
Its historical framework begins with James Harrington's seventeenth-century architecture of rotation and equal vacations and follows the development of these mechanisms through later constitutional arrangements and modern term-limit systems.
The historical record provides a basis for examining how different institutions organize continuity and renewal through the eligibility rules governing public office.
