Whether Massachusetts' absolute veterans' preference created an overt or covert gender classification subject to heightened equal-protection scrutiny.
Holding
No. The statute classified applicants by veteran status, not by sex, and it was not a pretext for preferring men over women.
Reasoning
The Equal Protection Clause does not forbid every law that distributes benefits and burdens unevenly. A law that expressly classifies by sex, or uses a facially neutral classification as a pretext for sex discrimination, requires an exceedingly persuasive justification. But a neutral law with unequal effects does not become a sex classification merely because women are disproportionately burdened.
The statute was facially gender neutral: it extended its preference to any qualified veteran, male or female. Massachusetts had consistently included women who served in official military units and, later, women who served in qualifying auxiliary units. Veteran status was therefore not a status uniquely reserved for men, even though relatively few women had been able to attain it.
The preference also disadvantaged many men because substantial numbers of men were nonveterans. Its effect could be explained directly by its legitimate purpose of favoring veterans for their service, easing their return to civilian life, and rewarding military sacrifice. Those purposes, rather than an effort to reserve public jobs for men, supplied the plausible and actual explanation for the statute's classification and impact.
