Whether Title VII categorically excludes a hostile-work-environment claim when the alleged harasser and the victim are of the same sex.
Holding
No. Same-sex sexual harassment can constitute discrimination "because of ... sex" and is actionable under Title VII when the statute's requirements are met.
Reasoning
Title VII forbids an employer to discriminate against an individual in the terms, conditions, or privileges of employment because of that individual's sex. The Court had already held that this language reaches a hostile environment created by severe or pervasive discriminatory intimidation, ridicule, and insult. Its protection extends to men as well as women, and neither the statutory text nor prior decisions makes coverage turn on whether the harasser and victim are of opposite sexes.
The Court rejected a categorical assumption that a person cannot discriminate against someone of the same sex. Its prior cases had similarly refused to presume that members of the same racial group could not discriminate against one another, and a male employee's sex-discrimination claim did not become legally insignificant merely because the decisionmaker was male.
Although male-on-male harassment may not have been Congress's principal concern in enacting Title VII, statutory language can reach reasonably comparable harms beyond the principal evil that motivated the law. Once sexual harassment is understood as a form of discrimination in employment conditions because of sex, the rule applies to same-sex harassment as well as opposite-sex harassment.
