A standard of judicial review under which a classification or regulation is upheld if it bears a rational relationship to a legitimate governmental interest. Courts apply this test to classifications that do not involve suspect classes or fundamental rights and defer to legislative judgments so long as the measure is not arbitrary or wholly unrelated to its stated purpose.
The city council enacts an ordinance requiring all police officers to retire at age fifty. Officer Rebecca Ross, who remains physically fit, challenges the rule. The court upholds the ordinance because the age limit advances the legitimate goal of maintaining a capable force and satisfies the rational relation test.
The President issues an order limiting visas for nationals from several countries identified as posing cybersecurity risks. Rajesh Rao, a software engineer from one of the listed countries, sues claiming religious animus. The court applies the rational relation test and sustains the order because it states a national security purpose rationally connected to the restrictions.

A state funds public schools primarily through local property taxes, resulting in lower per-pupil spending in poorer districts. Raymond Ramos, a parent in a low-wealth district, sues alleging unequal treatment. The court upholds the system under the rational relation test because the funding method rationally advances the legitimate interest in local control of education.
Congress bans possession of firearms within one thousand feet of a school. Robert Rivera, charged under the statute, argues the law exceeds federal power. The court applies the rational relation test in assessing the commerce power claim and finds the prohibition lacks a rational relationship to interstate commerce.
A state imposes higher taxes on out-of-state insurance companies than on domestic insurers. Reliance Insurance challenges the tax as discriminatory. The court sustains the statute under the rational relation test because the distinction rationally furthers the legitimate goal of encouraging local investment in the insurance industry.
Congress amends the Age Discrimination in Employment Act to allow private damages suits against states. Roberto Reyes, a state employee denied promotion because of age, sues for damages. The court holds that the remedy fails the rational relation test congruence requirement because age classifications receive only rational basis review and Congress identified no pattern of unconstitutional state conduct.
The rational relation test applies to classifications that do not involve suspect classes such as race or national origin and do not burden fundamental rights. Gender classifications receive intermediate scrutiny while age and most economic distinctions receive rational basis review.
No. In the immigration and foreign affairs context the court focuses on whether the measure states a facially legitimate purpose rationally related to that purpose even when statements suggest animus. The test does not require proof of perfect motives.
Yes. Laws may be imperfectly tailored so long as they are rationally related to a legitimate purpose. Courts permit legislative first steps and administrative convenience justifications under this standard.
Congress may enforce the Fourteenth Amendment only through remedies that are congruent and proportional to identified constitutional violations. Because age and disability classifications receive rational basis review, broad damages remedies often exceed that standard.
