Whether the Fifth Amendment protects a congressional employee against unconstitutional sex discrimination by a Member of Congress.
Holding
Yes. The equal-protection component of the Fifth Amendment’s Due Process Clause gives Davis a personal constitutional right to be free from federal sex discrimination that lacks an important governmental objective and a substantial relation to that objective.
Reasoning
The Fifth Amendment’s Due Process Clause applies equal-protection principles to the federal government. Under the Court’s sex-discrimination precedents, a gender classification must serve important governmental objectives and be substantially related to achieving those objectives.
Passman’s employment decision was federal action even if it was allegedly unlawful. A federal official does not cease acting under federal authority merely because he misuses that authority. The Court did not decide whether Passman’s asserted justification could satisfy the applicable constitutional standard.
