Final answer:
A law that classifies individuals by their race, religion, or nationality is subject to strict scrutiny by the Supreme Court to ensure it is constitutional, requiring the government to justify the law with a compelling interest.
Step-by-step explanation:
A law that classifies people according to race, religion, or nationality will be given strict scrutiny by the Supreme Court to determine its constitutionality. Strict scrutiny is the highest standard of review which the Court uses to evaluate laws that impact fundamental rights or involve suspect classifications, such as race, nationality, and religion. Under this standard, the government must demonstrate that the law is narrowly tailored to achieve a compelling governmental interest and is the least restrictive means to achieve that interest. For instance, affirmative action policies often come under this degree of judicial examination.
