Worked Example: United States — Presidential Term Limits

The Twenty-Second Amendment to the United States Constitution establishes a categorical eligibility limit on the presidency. Ratified in 1951, it provides that no person may be elected to the office of President more than twice. It further specifies that a person who has served more than two years of a term to which another individual was elected may be elected only once, thereby incorporating partial-term service into the eligibility calculation. The Amendment includes a transitional provision stating that it does not apply to the individual holding the presidency at the time it was proposed by Congress. This transition creates a one-time historical exemption with no persistence beyond ratification and no creation of an exempt eligibility class. As written, the Amendment operates as a self-executing constitutional rule governing eligibility for office.

Normative Adequacy: Rotation and Authority

Under the Framework’s Normative Adequacy module, and distinct from its Structural Validity, the Twenty-Second Amendment performs strongly within the Doctrine governing rotation in office.

Entrenchment Risk — Low.
A hard ceiling on elections, combined with inclusion of substantial partial-term service, structurally prevents durable accumulation of formal executive power.

Careerism Incentive Risk — Low.
The eligibility boundary forecloses rational long-term career planning within the office beyond a short, finite horizon.

Rotation Cadence Weakness — Low.
Mandatory turnover after a predictable maximum tenure ensures regular disruption of elite continuity at the apex of executive authority.

Confidence ≠ Rotation Risk — Low.
Electoral approval cannot substitute for structural turnover. Once the eligibility ceiling is reached, reelection is categorically barred regardless of popularity or performance.

Civic Intelligibility Deficit — Moderate.
The two-election rule is widely understood, while the partial-term threshold and transitional clause introduce limited complexity that typically requires explanation.

Office ≠ Leadership Risk — Moderate.
Although formal office-holding is capped, the Amendment does not prevent continued informal influence, party leadership, or advisory dominance after departure.

Normative Adequacy — High.
The Amendment enforces rotation as a constraint on authority while preserving electoral choice within defined limits.

Why This Is a Clean Pass

This case illustrates what a structurally coherent and normatively aligned eligibility rule looks like when nothing breaks. The Twenty-Second Amendment separates confidence from duration by design: elections determine who may serve, while the Constitution determines how long any one person may hold executive power. The rule is bounded, equally applicable after transition, administrable without discretion, and resistant to common forms of circumvention. Its durability and acceptance reflect not optimization or fine-tuning, but alignment with a widely recognized boundary on authority—two terms and out.

Why This Case Matters

The Twenty-Second Amendment is a rare example of an enacted, constitutionally embedded eligibility limit operating across generations. Because it is settled law and detached from contemporary political actors, it provides a neutral reference point for understanding how the Framework evaluates structural coherence and normative adequacy. As the first Worked Example, it establishes what a clean pass looks like before turning to more complex and contested designs.
