Legal Definition
Rational basis.
Plain English Explanation
The Equal Protection Clause of the Fourteenth Amendment ensures that no state shall deny any person within its jurisdiction "the equal protection of the laws." This means that laws should treat people fairly. However, not all classifications or distinctions made by laws are judged equally strictly by courts.
When it comes to laws that classify people based on characteristics other than fundamental rights (like the right to vote), suspect classes (like race), or quasi-suspect classes (like gender), courts use something called the "rational basis test" to decide if these classifications are acceptable.
The rational basis test is the easiest standard for a law to meet. Under this test, the law is presumed to be valid as long as it is rationally related to a legitimate government interest. In simpler terms, if the government can show that the law is reasonable and serves a legitimate purpose, it will likely be upheld. This contrasts with stricter tests used for classifications involving fundamental rights or suspect and quasi-suspect classes, where the government must provide stronger justifications for the laws.
This rule exists because not all classifications by the government are harmful or unfair. For example, age restrictions for driving or drinking are based on reasonable judgments about safety and maturity, and thus are evaluated under this lenient standard.

Hypothetical
Hypo 1: Bob applies for a job as a firefighter, but the city of Hypofornia has a rule that applicants must be at least 21 years old. Bob, who is 19, sues the city, claiming that the age requirement violates his right to equal protection under the law.
Result: The court will apply the rational basis test to evaluate this age classification. Since the age requirement is likely based on the reasonable assumption that individuals 21 and older are more physically and mentally mature for the demanding job of a firefighter, the court will probably find that the rule is rationally related to a legitimate government interest in public safety and will uphold the age restriction.
Hypo 2: Sam challenges a law in New Hypoland that offers tax credits only to new businesses owned by residents of the state, arguing that it discriminates against non-residents and violates the Equal Protection Clause. Result: The court will use the rational basis test to assess this residency classification. The government can argue that the tax credits are designed to promote local economic development by encouraging new businesses within the state. This is a legitimate government interest, and as long as the residency requirement is seen as a reasonable way to achieve this goal, the court will likely uphold the law.
Hypo 3: Hypofornia passes a law requiring all professional drivers (such as taxi and truck drivers) to undergo annual health check-ups. Bob, a professional driver, claims this law is unconstitutional because it unfairly targets his profession. Result: The rational basis test will be applied to this occupational classification. The state can justify the law by citing the legitimate interest in ensuring the safety of its roads by making sure that professional drivers are in good health. As this is a reasonable and related measure to achieve public safety, the court will likely find the law valid.
Hypo 4: New Hypoland enacts a regulation that limits the number of pets per household to three. Sam, who owns four cats, argues that this regulation violates his equal protection rights. Result: The court will apply the rational basis test to this household pet limitation. The government can argue that the regulation aims to promote public health and prevent nuisances. As this is a legitimate interest and the regulation is a reasonable means to achieve it, the court will likely uphold the limitation.
