Mathews v. De Castro
The Supreme Court upheld a Social Security rule that pays monthly benefits to a married woman under 62 who cares for a dependent child when her husband retires or becomes disabled, but denies those same benefits to a divorced woman under 62 in the identical caregiving situation.
The Court found Congress had a rational basis for treating married and divorced women differently because divorce typically ends the couple's shared economic life, so the ruling reverses a lower court that had struck the distinction down as unconstitutional.
“So long as its judgments are rational, and not invidious, the legislature's efforts to tackle the problems of the poor and the needy are not subject to a constitutional straitjacket.”
The Court's guiding principle for reviewing Social Security's benefit classifications.
How it got here: A three-judge federal district court ruled the age distinction for divorced wives unconstitutional; the Secretary of Health, Education, and Welfare appealed directly to the Supreme Court.
The Case in Depth
What happened
Helen De Castro divorced her husband in 1968 after more than 20 years of marriage and cares for a disabled child who receives child's insurance benefits. When her ex-husband began receiving old-age benefits, she applied for wife's insurance benefits at age 56 but was denied because divorced wives under 62 are not eligible, even though married wives under 62 with a dependent child in their care are eligible.
The question before the Court
Could Social Security deny monthly benefits to a divorced woman under 62 caring for a dependent child, while paying those same benefits to a married woman in the same situation?
The Court's answer
Yes — the Court ruled that Congress could rationally give benefits to a married wife under 62 with a dependent child while denying those same benefits to a divorced wife under 62 in the same caregiving role. Social Security's insurance benefits are meant to replace income lost when a family's wage earner stops working, not to address general financial need, so comparing which group needs money more missed the point.
Congress could reasonably assume that married couples still share finances and caregiving burdens after one spouse retires or becomes disabled, while divorced couples generally live separate economic lives. Because that assumption was rational, even though imperfect, the age distinction survived the lenient constitutional review that applies to economic and social welfare legislation, and the lower court's ruling striking it down was reversed.

Why it matters
Divorced women under 62 who care for a dependent child will continue to be denied wife's insurance benefits under Social Security even if their ex-husband retires or becomes disabled, while married women in the same caregiving role keep receiving those payments regardless of age. The decision leaves this age-and-marital-status distinction in place nationwide.
What changes now
The Supreme Court's reversal is a final decision on the merits, meaning the Social Security provision denying benefits to divorced wives under 62 remains valid and enforceable. Helen De Castro will not receive wife's insurance benefits until she turns 62. The ruling forecloses similar constitutional challenges to this specific age-and-marital-status distinction unless Congress amends the statute.
What this does not decide
The Court did not decide whether divorced women who actually receive alimony or child support that stops when a former husband retires have a stronger constitutional claim, noting Congress was not required to use Social Security to guarantee those support payments either. It also did not address widow's or mother's benefits, which are governed by different provisions.

How the Court got there
The legal reasoning, step by step
- The Court applied a rational-basis test — the most lenient level of constitutional review, under which a law is upheld if Congress could reasonably have had a legitimate reason for it, even if the law is imperfect or occasionally produces unequal results.
- The Court explained that Social Security's old-age and disability insurance programs are not general welfare payments based on need, but are meant to replace lost family income when a wage earner stops working, so need-based comparisons between divorced and married caregivers were beside the point.
- The Court reasoned that Congress could rationally believe that married couples still share income, expenses, and caregiving burdens when a husband retires or becomes disabled, while divorced couples typically live separate financial lives and no longer depend on each other in the same way.
- Because divorce could rationally be assumed to reduce a couple's financial interdependence, the Court concluded Congress could rationally decide to delay benefits for divorced wives until they reach 62, even though this line does not perfectly match every divorced woman's actual circumstances.
- The Court reaffirmed that a statute need not precisely capture every person whose situation matches the concern behind it to survive rational-basis review, so the age distinction for divorced wives did not violate the Fifth Amendment's guarantee of equal treatment under federal law.
