A classification that the Supreme Court has identified as warranting strict scrutiny under the Equal Protection Clause because it rests on a characteristic such as race or alienage that historically has been used to disadvantage discrete and insular minorities.
Isaac Irving, a physically fit fifty-one-year-old officer, challenged a city rule requiring retirement at age fifty. The court applied rational basis review because age is not a characteristic that triggers strict scrutiny. The rule survived because it was rationally related to maintaining a capable force.
Isla Ireland's children were assigned to schools based solely on their race to achieve demographic balance. The court subjected the policy to strict scrutiny because racial classifications are inherently suspect and require a compelling interest and narrow tailoring.

India Inoue sued after the city authorized a cable company to install equipment on her building without consent. The court treated the permanent physical occupation as a per se taking rather than evaluating it under an equal protection framework that would require an inherently suspect classification.
Ilana Isaacs challenged a property-tax system that produced lower funding in poorer districts. The court applied rational basis review because wealth is not an inherently suspect classification and education is not a fundamental right.
Ike Ingram was denied admission after a public program automatically awarded substantial points to applicants from favored racial groups. The court applied strict scrutiny because racial classifications are inherently suspect and the mechanical point system failed narrow tailoring.
Idina Iverson's children were barred from public school because of their immigration status. The court applied heightened review because the classification burdened a discrete group in a manner that implicated equal protection concerns beyond ordinary rational basis.
The Court treats classifications based on race, alienage, and national origin as inherently suspect and therefore subject to strict scrutiny. Sex-based classifications receive intermediate scrutiny rather than strict scrutiny.
No. Age is not an inherently suspect classification, so age-based distinctions receive only rational basis review even when they affect physically fit individuals.
Strict scrutiny applies. The government must show that the classification serves a compelling interest and is narrowly tailored to achieve that interest.
No. Wealth-based distinctions receive rational basis review, as do disparities in school funding that result from local property taxes.
A facially neutral law that produces a disparate impact on a suspect class does not trigger strict scrutiny unless the plaintiff proves discriminatory purpose. The classification itself must be inherently suspect to invoke that standard.
…protection claim must fail, since it is not to be judged by the strict scrutiny standard employed when a fundamental interest or suspect classification is involved, see, e. g. , Dunn v. Blumstein , 405 U. S. 330 (1972), and Korematsu v. United States , 323 U. S. 214 (1944), or by the somewhat less strict standard of Craig v. Boren ,…
