A standard of judicial review under which legislation is upheld if it bears a rational relation to a legitimate governmental interest. The test demands only minimal connection between the means chosen and the end pursued. Courts applying the standard defer heavily to legislative judgments and uphold laws even when they are underinclusive or overinclusive.
Marcus Mitchell, a physically fit fifty-one-year-old officer, sues after the city enforces a rule requiring retirement at age fifty. The court applies minimum rationality and upholds the rule because the age limit is rationally related to the legitimate goal of maintaining a capable police force. Mitchell's individual fitness does not change the outcome.
Angelica, a pilot trainee from a majority-Muslim country, challenges an executive order barring entry from designated nations. The court applies minimum rationality in the immigration context and upholds the order because it states a national-security purpose rationally related to the restrictions. Prior statements suggesting improper motive do not alter the result.

Meridian Motors, an out-of-state insurer, challenges a state tax that favors domestic companies. The court applies minimum rationality and sustains the tax because it is rationally related to the legitimate goal of encouraging in-state insurance business. The classification survives deferential review.
Malcolm McKinley, a sixty-eight-year-old state judge, contests a mandatory retirement rule at age seventy. The court applies minimum rationality and upholds the statute because the age limit is rationally related to the legitimate interest in ensuring judicial vigor. The rule survives even though some older judges remain capable.
Minimum rationality applies to economic and social legislation that does not burden a fundamental right or target a suspect class. Courts ask only whether the law is rationally related to a legitimate governmental interest. Deference to legislative judgments is the norm under this standard.

Yes. Laws may be underinclusive or overinclusive so long as they are rationally related to a legitimate purpose. Courts accept incremental legislative steps toward a goal without demanding perfect fit.
No. Federal alienage classifications receive deferential rational-basis-type review because Congress holds plenary power over immigration. State alienage classifications generally trigger strict scrutiny, but federal distinctions between citizens and noncitizens are upheld if not arbitrary or unreasonable.
