Also known as: arbitrarily or unreasonably
Written by attorneys · grounded in primary & secondary sources — see below
A deferential standard of review applied to federal classifications based on alienage. Under the standard a classification survives equal protection scrutiny when it bears a rational relationship to a legitimate governmental purpose such as conserving limited resources or confirming long-term ties to the national community.
Congress enacts a Medicare regulation that conditions eligibility on five years of lawful permanent residence. Luis, a long-term resident alien who has paid taxes for a decade, is denied benefits solely because he falls short of the residency threshold. The court applies the deferential standard and upholds the rule because the durational requirement rationally advances the federal interest in tying benefits to sustained national membership.
Congress restricts motorboat use on certain international boundary waters to protect the environment. Ontario challenges the restriction as inconsistent with a treaty guaranteeing free navigation. The court finds the federal construction of the treaty not arbitrary or unreasonable because the regulation reasonably accommodates commerce while preserving the treaty's core guarantee of open intercourse between the nations.

Federal alienage classifications receive deferential rational-basis review rather than strict scrutiny. The classification is valid if it is not arbitrary or unreasonable and bears a rational relationship to a legitimate federal purpose such as resource conservation or confirming long-term ties to the United States.
Supporting sources
No. Courts uphold such requirements under the deferential standard because Congress may rationally tie benefits to sustained residence even when the line excludes some long-term lawful residents.
Supporting sources
State alienage classifications usually trigger strict scrutiny. Federal classifications receive only rational-basis review because Congress possesses plenary power over immigration and the status of noncitizens.
Supporting sources
No. The deferential standard does not permit courts to second-guess Congress's choice of a uniform bright-line rule even when particular applicants demonstrate equivalent stability or contribution.
