Mathews v. De Castro

Background

A divorced woman, Helen De Castro, cared for a disabled child whose benefits were tied to her former husband’s Social Security. Her ex‑husband began receiving old‑age benefits, but because she was only 56 the agency denied her wife’s insurance benefits that a married woman in the same situation would receive. A three‑judge District Court held the rule unlawfully discriminated against divorced wives and ordered benefits paid; the Secretary appealed to the Supreme Court.

Reasoning

The Court asked whether Congress could reasonably treat married and divorced women differently for these specific Social Security payments. It explained that these insurance benefits are designed to protect families when a breadwinner retires or becomes disabled, not to serve as general need‑based aid. The Court concluded Congress could rationally focus on the financial disruption that occurs when a married couple continues to live together and lose the wage earner’s support. Because divorced couples typically live separate lives and may face different problems, Congress could lawfully postpone similar payments to divorced wives until age 62. The Court therefore found no violation of the Fifth Amendment’s requirement of equal treatment and reversed the lower court.

Real world impact

The ruling means divorced women under 62 who care for children entitled to child benefits will generally remain ineligible for wife’s insurance benefits, while married women in the same caregiving role can receive them immediately when the husband retires or is disabled. The decision rests on Congress’s policy choice about whom the insurance program is meant to protect and does not require the Social Security program to substitute for alimony or child‑support shortfalls.

Dissents or concurrances

Justice Marshall joined the Court’s judgment without a separate opinion, concurring in the result.
