Califano
v.
Goldfarb,
I
A
The Social Security Act (Act) provides spousal benefits for the wives, husbands, widows, and widowers of retired and disabled wage earners. 42 U. S. C. § 402 (1976 ed. and Supp. V). Prior to December 1977, benefits were payable only to those husbands or widowers who could demonstrate dependency on their wage-earning wives for one-half of their support. Wives and widows, on the other hand, were entitled to spousal benefits without any such showing of dependency on their husbands. See former 42 U. S. C. §§ 402(b), (c)(1)(C), and (f)(1)(D). In March 1977,
Califano
v.
Goldfarb, supra,
affirmed the judgment of a three-judge District Court which held that the gender-based dependency requirement for widowers violated the equal protection component of the Due Process Clause of the Fifth Amendment.

Subsequently, the Court summarily affirmed two District Court decisions invalidating the dependency requirement for husbands’ benefits.
Califano
v.
Silbowitz,
Following these decisions, as part of a general reform of the Social Security system, Congress repealed the dependency requirement for widowers and husbands. Social Security
To avoid this fiscal drain, Congress included as part of the 1977 Amendments a “pension offset” provision that generally requires the reduction of spousal benefits by the amount of certain Federal or State Government pensions received by the Social Security applicant. 1977 Amendments, §§334 (a)(2) and (b)(2), 42 U. S. C. §§ 402(b)(4)(A) and (c)(2)(A) (1976 ed., Supp. V). Congress estimated that 90 percent of the savings that would be achieved by the pension offset provision as proposed by the Senate would be attributable to a reduction in payments to nondependent husbands and widowers who had not been entitled to any spousal benefits prior to
“If any provision of this subsection, or the application thereof to any person or circumstance, is held invalid, the remainder of this section shall not be affected thereby, but the application of this subsection to any other persons or circumstances shall also be considered invalid.” 1977 Amendments, § 334(g)(3), note following 42 U. S. C. §402 (1976 ed., Supp. V).
The Conference Committee explained that the severability clause was enacted “so that if [the exception to the pension offset provision] is found invalid the pension-offset. . . would not be affected, and the application of the exception clause would not be broadened to include persons or circumstances that are not included within it.” H. R. Conf. Rep. No. 95-837, pp. 71-72 (1977); S. Conf. Rep. No. 95-612, pp. 71-72 (1977).

Appellee Robert H. Mathews (hereafter Mathews or appel-lee) retired from his job with the United States Postal Service on November 18, 1977. His wife, who had retired from her job a few months earlier, was fully insured under the
Mathews and his wife then brought this class action against the Secretary in the United States District Court for the Northern District of Alabama under § 205(g) of the Act, 42 U. S. C. 405(g). The complaint alleged that application of the pension offset provision of the 1977 Amendments to Mathews and other nondependent men but not to similarly situated nondependent women violated the Due Process Clause of the Fifth Amendment and sought a declaratory judgment to that effect. Appellee also contended that the severability clause of the 1977 Amendments was unconstitutional. The District Court certified a nationwide class composed of “all applicants for husband’s insurance benefits . . . whose applications . . . have been denied [beginning 60 days before the filing of the complaint] solely because of the statutory requirement that husbands must have received more than one-half of their support from their wives in order to be entitled to benefits.” App. to Juris. Statement 10a.
Shortly thereafter, the District Court filed an opinion,

at la-9a, and order,

at 27a-28a, holding both the pension offset exception of § 334(g)(1)(B) and the severability clause of § 334(g)(3) unconstitutional. The court noted that, in es
Having invalidated the exception to the offset provision, the District Court considered the severability clause of § 334(g)(3). The court noted that, in the event appellee obtained a judgment that the offset exception unconstitutionally discriminates against him, the clause, if valid, would require nullification of the exception as to all persons, rather than extension of the exception to persons like appellee. Consequently, all government retirees not covered by Social Security, without regard to gender or dependency, would have their spousal benefits offset by the amount of their government pensions. The court characterized this effect of the severability clause as an effort by Congress “to mandate the

Although the severability clause would prevent a court from redressing this inequality by increasing the benefits payable to appellee, we have never suggested that the injuries caused by a constitutionally underinclusive scheme can be remedied only by extending the program’s benefits to the excluded class. To the contrary, we have noted that a court sustaining such a claim faces “two remedial alternatives: [it] may either declare [the statute] a nullity and order that its benefits not extend to the class that the legislature intended to benefit, or it may extend the coverage of the statute to include those who are aggrieved by the exclusion.”

decision and the resulting amendments to the Act, see H. R. Conf. Rep. No. 95-837, p. 72 (1977); S. Conf. Rep. No. 95-612, p. 72 (1977), Congress exempted from the offset requirement those individuals eligible for spousal benefits under the Act “as it was in effect and being administered in January 1977.” There can be no dispute that in January 1977 men were eligible for benefits only upon a showing of dependency whereas women were subject to no such requirement. See former 42 U. S. C. §§ 402(c) and (f);

We recently reviewed the “firmly established principles by which to evaluate a claim of gender discrimination like that made by appellee:
“Our decisions . . . establish that the party seeking to uphold a statute that classifies individuals on the basis of their gender must carry the burden of showing an ‘exceedingly persuasive justification’ for the classification. . . . The burden is met only by showing at least that the classification serves ‘important governmental objectives and that the discriminatory means employed’ are ‘substantially related to the achievement of those objectives.’. . .
“Although the test for determining the validity of a gender-based classification is straightforward, it must be applied free of fixed notions concerning the roles and abilities of males and females. Care must be taken in ascertaining whether the statutory objective itself reflects archaic and stereotypic notions. Thus, if the statutory objective is to exclude or ‘protect’ members of one gender because they are presumed to suffer from an inherent handicap or to be innately inferior, the objective itself is illegitimate. . . .
“If the State’s objective is legitimate and important, we next determine whether the requisite direct, substantial relationship between objective and means is present.” Mississippi University for Women v. Hogan,458 U. S., at 724-725 . (Citations and footnotes omitted.)

Although the offset exception temporarily revives the gender-based eligibility requirements invalidated in
Gold-farb,
Congress’ purpose in adopting the exception bears no relationship to the concerns that animated the original enactment of those criteria. The Court concluded in
Goldfarb
that the original gender-based standards, which were premised on an assumption that females would normally be dependent on the earnings of their spouses but males would not, constituted an “accidental byproduct of a traditional way of thinking about females,”
The provision at issue here, in contrast, reflects no such illegitimate government purposes. As detailed above, Congress adopted the offset exception in order to protect the expectations of persons, both men and women, who had planned their retirements based on pre-January 1977 law, under which they could receive spousal benefits unreduced by the amount of any government pensions to which they were also entitled. Congress accomplished its aim by incor
Nor is that purpose rendered illegitimate by the fact that it is achieved through a temporary revival of an invalidated classification. We have recognized, in a number of contexts, the legitimacy of protecting reasonable reliance on prior law even when that requires allowing an unconstitutional statute to remain in effect for a limited period of time. See,
e. g., Northern Pipeline Construction Co.
v.
Marathon Pipe Line Co.,
The protection of reasonable reliance interests is not only a legitimate governmental objective: it provides “an exceedingly persuasive justification” for the statute at issue here. See
Kirchberg
v.
Feenstra,
“Many couples have undoubtedly made retirement plans and adjusted the level of their private saving and investment in anticipation of retirement benefits from social security which include a special benefit for a spouse. An abrupt denial of benefits in these cases, even if the spouse who would have received them is shown to be not truly dependent on the other is clearly inequitable since the couple’s savings and retirement plans would havebeen different had the spouse benefit not been anticipated. Thus, were it to be decided that wives should prove dependency in order to receive spouse benefits, a strong argument could be made for making such a change gradually so as to avoid inequities to couples approaching retirement who had anticipated that such benefits would be available to them and had made their retirement plans accordingly.” M. Flowers, Women and Social Security: An Institutional Dilemma 41 (1977).
In short, particularly in the years immediately preceding retirement, individuals make spending, savings, and investment decisions based on assumptions regarding the amount of income they expect to receive after they stop working. For such individuals reliance on the law in effect during those years may be critically important.
14
In recognition of this fact, the offset exception, in the words of the Conference Report, protects “people who are already retired, or close to retirement, from public employment and who cannot be expected to readjust their retirement plans to take account of the ‘offset’ provision that will apply in the future.” H. R. Conf. Rep. No. 95-837, p. 72 (1977); S. Conf. Rep. No. 95-612, p. 72 (1977). That purpose, consistent with the principle that “ ‘[gjreat nations, like great men, should keep their word,’”

At the same time, Congress directed the Department of Health, Education, and Welfare to include “the entire question of such gender-based distinctions ... in [a] 6-month study of proposals to eliminate dependency and sex discrimination H. R. Conf. Rep. No. 95-837, p. 73 (1977). Thereafter, other gender-based distinctions were eliminated from the Act by the Social Security Amendments of 1983, Pub. L. 98-21, §§ 301-309, 97 Stat. 109-115; see H. R. Conf. Rep. No. 98-47, p. 140 (1983).
Section 334(g) of the 1977 Amendments, Pub. L. 95-216, 91 Stat. 1546, note following 42 U. S. C. § 402 (1976 ed., Supp. V), provides in full:
“(1) The amendments made by the preceding provisions of this section [section 334] shall not apply with respect to any monthly insurance benefit payable, under subsection (b), (c), (e), (f), or (g) (as the case may be) of section 202 of the Social Security Act, to an individual —
“(A) to whom there is payable for any month within the 60-month period beginning with the month in which this Act is enacted (or who is eligible in any such month for) a monthly periodic benefit (within the meaning of such provisions) based upon such individual’s earnings while in the service of the Federal Government or any State or political subdivision thereof, as defined in section 218(b)(2) of the Social Security Act); and
“(B) who at time of application for or initial entitlement to such monthly insurance benefit under such subsection (b), (c), (e), (f), or (g) meets the requirements of that subsection as it was in effect and being administered in January 1977.
“(2) For purposes of paragraph (1)(A), an individual is eligible for monthly periodic benefit for any month if such benefit would be payable to such individual for that month if such individual were not employed during that month and had made proper application for such benefit.
“(3) If any provision of this subsection, or the application thereof to any person or circumstance, is held invalid, the remainder of this section shallnot be affected thereby, but the application of this subsection to any other persons or circumstances shall also be considered invalid.”
On January 12, 1983, Congress created an exception from the pension offset provision for any person eligible for a pension prior to July 1983 who satisfies a half-support dependency test. Pub. L. 97-455, § 7, 96 Stat. 2501. On April 20, 1983, Congress revised the pension offset provision, which is now applicable to all persons, without exception, who become eligible to retire in or after July 1983 and which requires the offsetting of only two-thirds of the public pension. Pub. L. 98-21, § 337, 97 Stat. 131. The exception to the offset provision at issue in this case still applies to non-dependent women eligible for pensions prior to December 1982 but not to such nondependent men as the named plaintiff in this action. Accordingly, the recent amendments to the Act do not moot this case.

In that case, the Court concluded that indigents, who contended that they were denied medical treatment by tax-exempt hospitals, lacked standing to challenge the Government’s allegedly unlawful administration of the Tax Code because it was “purely speculative” whether their injury was caused by the
This conclusion, contrary to appellee’s suggestion, is not altered by the fact that in January 1977 the SSA was withholding disputed benefit claims pending this Court’s disposition of Goldfarb. The Social Security Claims Manual in effect at the time notes: “The current law requires that claimants for (widower’s) (husband’s) benefits meet a one-half support requirement. [While that requirement has been challenged in court], the law remains unchanged and no payment can be made until a final decision has been rendered on the constitutionality of the one-half support requirement.” Social Security Administration Claims Manual Transmittal No. 3844 (July 14,1976). Thus, the Manual indicates that, as provided by the extant provisions of the Act, the SSA did not in January 1977 pay benefits to male claimaints who failed to demonstrate dependency on their wives.
The only individuals identified by appellee who would be subject to the offset requirement under his interpretation of the Act are those who first became eligible for spousal benefits after enactment of the statute in December 1977. See Brief for Appellees 23-24; Reply Brief for Appellant 4, 5, n. 2. For example, the 1977 Amendments shortened the number of years a divorced wife must be married before being eligible for spousal benefits, effective December 1978, Pub. L. 95-216, § 337, 91 Stat. 1548, 42 U. S. C. §§ 402(b)(1)(G), 416(d) (1976 ed., Supp. V), and a number of judicial decisions just prior and subsequent to the Amendments extended eligibility for benefits to new categories of individuals, see,

See H. R. Conf. Rep. No. 95-837, p. 72 (1977) (“The managers are concerned that there may be large numbers of women, especially widows in their late fifties, who are already drawing pensions, or would be eligible to draw them within 5 years of the date of enactment of this bill, based on their non-covered work and whose retirement income was planned for on the assumption of the availability of full wife’s or widow’s benefits under social security”); S. Conf. Rep. No. 95-612, p. 72 (1977) (same); Staff of Senate Committee on Finance, 95th Cong., 1st Sess., Summary of H. R. 9346, the Social Security Amendments of 1977 as Passed by the Congress (P. L. 95-216) 7 (Comm. Print 1977) (“To assure that persons who have been counting on these benefits for many years and who are now at or near retirement age will not be adversely affected, H. R. 9346 includes a transitional exception under which certain individuals will not have their social security benefits as spouses reduced by the amount of their public pension. This exception applies to those who . . . would qualify for spouses benefits under social security under the law as in effect and as administered in January 1977”).
Indeed, the Social Security Act itself recognizes the critical importance of protecting an individual’s expectation of benefits even in circumstances where payment is contrary to current law. The Act forbids recovery of such overpayments when the recipient is not at fault and recapture “would be against equity and good conscience.” 42 U. S. C. § 404(b).
The latter group includes persons who first became entitled to spousal benefits under the 1977 Amendments themselves as well as those whose eligibility was first established in judicial decisions issued from 1977 to the present. See n. 11, supra. Because the offset provision was enacted at the end of 1977, the only members of this group who, under the law in effect at any given time, might have expected to receive spousal benefits unreduced by their government pensions are those who became eligible during 1977 as a result of Goldfarb and other decisions announced that year. The Act protects the reliance interests of most such people, however, by providing that the offset applies only to applicants who file their claims for spousal benefits in or after December 1977, the month of enactment of the Amendments. 1977 Amendments § 334(f), Pub. L. 95-216, 91 Stat. 1546, note following 42 U. S. C. §402 (1976 ed., Supp. V).
