Worked Example — Aggregation, Equal Application, and Transition Illustration

Framework Classification

Aggregation and Transition Architecture

Response Pattern

Canonical Eligibility Architecture

This Worked Example serves as the canonical reference architecture for evaluating eligibility designs under Structural Validity and Normative Adequacy, and for distinguishing eligibility-exhaustion systems from permission-preserving regimes.

It demonstrates how aggregation, equal application, and transition function together as a coherent eligibility architecture, independent of any specific office, amendment, or numerical limit.

In this illustration, eligibility exhaustion operates along the duration-vector, with elections functioning as discrete authorization events that cumulatively exhaust eligibility by rule.

Structural Function

This Worked Example illustrates how an election-based eligibility system can be structured in a clear, self-executing, and model-neutral way. Instead, it demonstrates how the core structural components of aggregation, equal application, transition, revision authority, and administrative posture function together as a coherent eligibility architecture exhibiting architectural integrity, without exemptions, resets, or discretionary enforcement.

This canonical eligibility architecture is intentionally constructed to terminate eligibility through duration-vector exhaustion rather than regulate continuity.

Designs that omit permanent exhaustion or permit eligibility to regenerate through absence, sequencing, or interpretive reset may share surface features with this model while producing materially different outcomes in practice.

This example is intended to be read alongside the Framework and Rotation Logic pages as a concrete illustration of those concepts in operation.

I. Aggregation — What Counts, and How It Accumulates

Core aggregation rule

Each time a person is elected to an office that carries a defined term of service, that election adds to the person’s lifetime total of permitted elections for that office (or office class), regardless of when the elections occur or whether the service is consecutive, and that total does not restart after time out of office.

Office classes and mobility

Which elections add to the same total depends on how the rule groups offices—for example, by the same office, the same chamber, or a specified category of offices—as stated in the rule.

This grouping determines how service across districts, states, or chambers is treated. Mobility does not reset eligibility unless the rule explicitly defines offices as belonging to separate classes.

Unit of eligibility exhaustion

The basic unit of eligibility exhaustion is an election win: each qualifying election counts as one unit toward the limit.

Appointive service

Service obtained by appointment counts only if the person serves more than a defined portion of the term; if so, it counts as one election-equivalent unit, as specified by the rule.

Partial service and special elections

Elections that authorize service for less than a full term—such as special elections or elections followed by early resignation—are treated the same as other elections unless the rule explicitly provides otherwise.

Interpretive note (authorization logic)

Election wins are used as the unit because an election is the act that authorizes service: it is the public decision that confers the right to hold the office for a term, and it can be identified and applied without further interpretation or administrative judgment.

Administrative note (self-executing structure)

Election-based aggregation is self-executing when the rule identifies a clear authorization event, specifies how partial service is treated, and allows eligibility to be determined directly from objective election records without supplemental interpretation.

In such systems, administrators need only identify qualifying elections and apply the counting rule as written. Eligibility exhaustion follows automatically from the accumulation of defined authorization events rather than from discretionary judgments about service duration, calendar years, intent, performance, or other external factors.

The Twenty-Second Amendment provides a familiar example. Eligibility is determined by counting presidential elections won together with a specified rule governing partial service following succession. Because both the authorization event and the treatment of partial service are defined within the rule itself, eligibility can be determined directly from the constitutional text and election record.

II. Equal Application — Single-Class Eligibility

Equal application describes a property of the aggregation rule: whether it applies uniformly to all similarly situated cases. Equal application is a necessary condition for duration-vector exhaustion to operate as a system-level self-correction rather than as a cohort-dependent constraint.

Under equal application, all qualifying elections within the defined office class are treated the same way, without permanent exemptions, eligibility restoration, or carve-outs for particular individuals or groups.

Transition failure mode: multi-class exemption

A transition design fails structurally when it exempts current officeholders from the rule until they leave office, creating multiple classes of eligibility and concentrating seniority during the transition period as a structural consequence. This failure mode is commonly described as “grandfathering.” Historically, however, grandfathering has not functioned as a distinct term-limit architecture and has not appeared in enacted voter-adopted term-limit systems.

III. Transition — When the Rule Begins to Apply

Definition

A transition rule specifies how existing service and eligibility are treated at the moment the rule first takes effect.

Transition types (descriptive)

Transition rules generally differ in how they treat elections or service that occurred before the rule takes effect:

  • Prior service fully counts: Elections or service that occurred before the rule takes effect are counted toward the limit in the same way as later elections.

  • Prior service is ignored: Only elections occurring after the rule takes effect are counted, and earlier elections are disregarded. Prospective counting alone does not create a separate eligibility class where all persons ultimately converge under the same endpoint structure.

  • Prior service is partially recognized: Prior elections or service are recognized through a finite transitional allowance, providing a limited, mechanically defined amount of additional eligibility that converges toward a unified eligibility regime.

A transition rule determines when eligibility limits begin to apply; it does not alter how eligibility is measured once application begins. Where a transition rule does not specify non-restoration, courts and administrators have historically interpreted silence in favor of continued eligibility rather than automatic exhaustion.

IV. Edge State — Incumbents at Activation

Definition

An edge state exists when a person holds an office covered by the rule at the moment the rule first takes effect.

Edge-state handling addresses how the rule begins applying to current officeholders; it does not change which elections count, how eligibility accumulates, or which offices are grouped together.

The sole question in an edge state is whether the officeholder’s current service is treated as authorized before or after the rule takes effect, as specified by the transition rule.

Edge-state handling fails structurally if it permanently exempts current officeholders from the rule, thereby creating a separate eligibility class.

V. Authority Over Revision — Durability as an Architectural Property

Definition

Authority over revision describes who holds the power to amend, reinterpret, suspend, or replace the eligibility rule after adoption, and under what conditions. Revision authority functions independently of aggregation, equal application, transition, and administrative posture, yet materially influences long-term architectural durability.

Structural relevance

The durability of an aggregation rule is an architectural property that depends not only on internal coherence, but on whether authority to revise, reinterpret, or suspend the rule is clearly allocated and symmetric with the authority that adopted it. When revision authority is displaced upward or consolidated away from the adopting locus, durability is reduced even where the eligibility architecture itself remains internally coherent.

Where revision authority is ambiguous, asymmetrical, or vested in actors subject to the rule, structurally coherent designs may be weakened post-ratification through reinterpretation or procedural substitution rather than formal amendment.

Scope limitation

This worked example specifies aggregation, equal application, transition, and administrative posture, but does not prescribe where revision authority should reside. The purpose of this section is to flag revision authority as a distinct structural variable that affects long-term stability without altering the design logic described above.

VI. Administrative Posture — How the Rule Is Applied

Definition

Administrative posture describes who applies the rule and how eligibility is determined in practice, without changing the substance of the rule itself.

Application of the rule consists of identifying qualifying elections, grouping them as specified, and determining whether the person has exhausted the permitted number of election units.

Administrative application does not involve evaluating intent, performance, residency motives, or the desirability of continued service.

Eligibility is determined at the point specified by election law, based on records of prior elections, and does not depend on future service outcomes.

Administrative application preserves architectural integrity by applying the governing rule as written rather than establishing eligibility rules through interpretation

VII. Non-Goals — Clarifying Boundaries

  • The rule does not regulate where, when, or how a person chooses to run for office; it only determines whether the person remains eligible based on prior elections.

  • The rule does not measure time served, effectiveness in office, or reasons for leaving office; it relies solely on the occurrence of qualifying elections.

  • The rule does not create permanent exemptions or separate eligibility classes for incumbents or any other group.

This Worked Example applies the Framework to a model-neutral eligibility architecture, illustrating how aggregation, equal application, and transition determine whether eligibility is exhausted or preserved.

For examples of how structurally coherent eligibility designs are later weakened through reinterpretation, procedural substitution, or asymmetric revision authority, see Institutional Response Patterns in Rotation Logic.
