Justice White first argued that the Court should have remanded the Title VII issue to the Court of Appeals rather than deciding it itself. The lower appellate court had not addressed that claim, and the majority's disposition depended on contesting factual inferences that had not been fully considered below.
On the merits, he concluded that respondents made a sufficient prima facie disparate-impact showing. The evidence that Black and Hispanic persons comprised about 63% of methadone users, compared with about 20% of the relevant workforce, supported the commonsense inference that the exclusion fell disproportionately on those groups. The Authority's refusal to permit discovery about rejected applicants, he reasoned, weakened its objection that the data did not precisely describe its own applicant pool.
Justice White also found the policy insufficiently job related under Title VII. The Authority had not shown that its blanket exclusion of successfully maintained methadone users improved workforce quality or that individualized consideration was prohibitively burdensome. Title VII, he emphasized, requires more probing review than rational-basis equal-protection analysis.
On equal protection, he would have upheld the District Court's finding that methadone users who had successfully remained in treatment for at least a year and avoided illicit drugs and problem drinking were no less employable in many jobs than ordinary applicants. The Authority could identify unsuccessful patients through ordinary screening and could still exclude qualified methadone users from genuinely safety-sensitive positions.
In his view, the majority justified excluding successful users by pointing to the risks posed by unsuccessful users, even though the successful and unsuccessful groups could be distinguished. It also failed to explain why methadone users alone could be categorically excluded while the Authority handled other potentially unreliable groups, such as problem drinkers and people with other medical histories, through individual assessment. That unequal treatment was arbitrary rather than rational.
