Under the Equal Protection Clause, discrimination against people with disabilities is analyzed by "rational basis" scrutiny: if the discrimination has a rational basis, it is constitutional. In this case, the Court held that Congress, like the judiciary, was required to use rational basis review of state action, with its presumptions favoring constitutionality. The Supreme Court decided that the legislative record of the ADA "fails to show that Congress did in fact identify a pattern of irrational state discrimination in employment against the disabled."
