A standard of judicial review that upholds a law or classification when it is rationally related to a legitimate government interest. The government need not prove the law is the best or most precise means to its end. Courts defer to legislative judgments and permit underinclusive or overinclusive rules so long as a rational connection exists.

Mandatory Police Retirement Age
Rebecca Ross, a fifty-one-year-old officer with excellent fitness scores, challenges the city rule forcing retirement at age fifty. The department defends the cutoff as a way to maintain a physically capable force. The court applies rational scrutiny and sustains the rule because the age line is rationally related to the legitimate goal of ensuring officer fitness.
Entry Restriction National Security Order
Raphael Rivera, a national of a majority-Muslim country, seeks entry to visit family but is barred by an executive order citing security risks at ports and military sites. The order states a national-security purpose and limits entry only from designated nations. Under rational scrutiny the court upholds the order because the restriction is rationally related to the stated security objective.

Age Discrimination Remedy Limits

Common questions
Frequently Asked
3
When does a court apply rational scrutiny instead of heightened scrutiny?+
Rational scrutiny applies when a law neither burdens a fundamental right nor draws a suspect or quasi-suspect classification. The government then need only show a rational relationship to a legitimate interest. Excerpts confirm that age, disability, and most economic or social classifications receive this deferential review.
Does rational scrutiny ever result in invalidation of a law?+
Yes. A law fails rational scrutiny when it rests on no legitimate interest or bears no rational relationship to the interest asserted. Excerpts illustrate invalidation when a classification is driven by mere prejudice or when cost savings alone cannot justify denying education to undocumented children.
How much deference does rational scrutiny give to legislative judgments?+
Courts give substantial deference. Laws may be underinclusive or overinclusive, and the government need not prove the classification is the best or most precise means to its end. Excerpts state that administrative convenience and a first-step approach toward a legitimate goal suffice.
