Justice Ginsburg emphasized that sex-based classifications must have "exceedingly persuasive justification."
Justice Ruth Bader Ginsburg, in her majority opinion on June 26, 1996, in the case of United States v. Virginia, set forth a new legal standard requiring an "exceedingly persuasive justification" for any gender-based classifications. This doctrinal articulation sharpened the standard of scrutiny for sex discrimination cases, elevating the judicial requirements that any institutional policies differentiated by gender had to meet. The enhanced standard became critical in subsequent equal protection analyses, ensuring greater fairness and equality under the law for women across various spheres, thus dismantling institutional gender barriers that had persisted for decades.
