A standard of judicial review under which legislation is upheld if it bears a rational relationship to a legitimate governmental interest. Courts defer to legislative judgments and sustain laws that are underinclusive or overinclusive so long as the classification is not arbitrary.

How it applies
Common Examples

Mandatory Police Retirement Age
Roland Rhodes, a physically fit 51-year-old officer, sues after the city enforces a retirement rule at age 50. The court evaluates whether the age cutoff connects to the city's interest in field readiness. Because the line rationally advances that objective, the rule stands even though some older officers remain capable.
Entry Restriction on Foreign Pilots
Angelica, a trainee pilot from a designated country, challenges an executive order barring entry on national-security grounds. The court examines whether the order's stated purpose of reducing hijacking risks rationally supports the restrictions. The policy survives because the political branches receive deference in immigration matters and the order advances that objective.

Federal Gun-Free School Zones Act
A high-school senior is prosecuted under a federal statute banning firearms near schools. The court reviews whether Congress had a rational basis for concluding that such possession affects interstate commerce. Because the legislative findings do not establish the required connection, the statute exceeds federal power.
United States v. Lopez514 U.S. 549 (1995)
Race-Based Student Assignment Plan
Parents in a school district challenge an assignment policy that uses race to achieve integration. The court applies strict scrutiny rather than the rationality standard because the classification rests on race. The plan fails because it is not narrowly tailored to a compelling interest.
Parents Involved in Community Schools v. Seattle School District No. 1551 U.S. 701, 127 S. Ct. 2738, 168 L. Ed. 2d 508 (2007)
State Age-Discrimination Suit
A group of older state employees sues under the Age Discrimination in Employment Act for money damages. The court determines that age classifications receive only the rationality standard and that Congress lacked a sufficient pattern of unconstitutional state conduct. The statute therefore exceeds Congress's enforcement power under the Fourteenth Amendment.
Kimel v. Florida Board of Regents528 U.S. 62, 80 (2000)
Mandatory Retirement for Judges
A sitting state judge challenges a constitutional provision requiring retirement at age 70. The court applies the rationality standard to the age classification. The provision survives because it rationally relates to the state's interest in judicial vigor and competence.

Common questions
Frequently Asked
4
What standard of review applies to age-based classifications?+
Age is not a suspect class, so laws drawing age lines receive the rationality standard and are upheld when rationally related to a legitimate governmental interest such as ensuring physical capability in law-enforcement roles.
How does the rationality standard apply to federal alienage classifications?+
Federal alienage distinctions receive at most the rationality standard because Congress holds plenary power over immigration. A residency or status requirement is sustained if it is not arbitrary or unreasonable and advances goals such as conserving benefits or easing administration.
When does Congress lack power under Section 5 to abrogate state sovereign immunity for age discrimination?+
Congress may not subject states to damages suits under the ADEA because age classifications receive only the rationality standard and the legislative record failed to show a pattern of irrational state discrimination that would justify the remedy.
Does the rationality standard permit underinclusive or overinclusive laws?+
Yes. Under the rationality standard a law may be underinclusive or overinclusive provided it is rationally related to a legitimate purpose. A city may begin with a partial ban on vehicle advertising even if the measure leaves some distractions untouched.
539 U.S. 558 (2003)Constitutional Law
…(1996); Nordlinger v. Hahn , 505 U. S. 1, 11-12 (1992). Laws such as economic or tax legislation that are scrutinized under rational basis review normally pass constitutional muster, since "the Constitution presumes that even improvident decisions will eventually be rectified by the democratic processes."
