Ten years after her illegitimate daughter's birth, petitioner
filed a support complaint on the daughter's behalf in Pennsylvania
state court, naming respondent as the father. Although a blood test
showed a 99.3% probability that respondent was the father, the
court entered judgment for respondent on the basis of a state
statute providing that actions to establish the paternity of an
illegitimate child ordinarily must be commenced within six years of
the child's birth. The court rejected petitioner's contentions that
the statute violates the Equal Protection and Due Process Clauses
of the Fourteenth Amendment to the Federal Constitution. While
petitioner's appeal to the Superior Court of Pennsylvania was
pending, the State adopted an 18-year statute of limitations for
paternity actions, in order to comply with a requirement of the
federal Child Support Enforcement Amendments of 1984 (federal Act).
The Superior Court concluded, however, that the new 18-year statute
of limitations did not apply retroactively, and that the 6-year
period would continue to apply in cases like petitioner's. The
court affirmed the trial court's conclusion that the 6-year statute
of limitations was constitutional.
Held:
1. Petitioner's contention that the 6-year statute of
limitations is invalid because it conflicts with an asserted
retroactivity requirement in the federal Act will not be addressed
by this Court, since the question of federal preemption was not
adequately presented to the Superior Court by petitioner's state
law retroactivity argument, and was not decided by that court. Pp.
486 U. S.
459-460.
2. The 6-year statute of limitations violates the Equal
Protection Clause. Under the heightened scrutiny analysis used in
evaluating equal protection challenges to statutes of limitations
that apply to illegitimate children's paternity suits, the period
for obtaining support must be sufficiently long to present a
reasonable opportunity for those with an interest in illegitimate
children to assert claims on their behalf, and any time limitation
placed on that opportunity must be substantially related to the
State's interest in avoiding the litigation of stale or fraudulent
claims.
Mills v. Habluetzel, 456 U. S.

Pickett v. Brown, 462 U. S.
1. Under this analysis, it is questionable whether
Pennsylvania's 6-year period is reasonable, since a mother may for
years after her child's birth be unwilling to assert a claim due to
her relationship with the natural father, the emotional strain of
having an illegitimate child, or the
Page 486 U. S. 457
desire to avoid community and family disapproval; since such a
mother might realize only belatedly a loss of income attributable
to the need to care for the child; and since financial difficulties
are likely to increase as the child matures and incurs additional
expenses. Moreover, that the 6-year period is not substantially
related to an interest in avoiding the litigation of stale or
fraudulent claims is established by a number of Pennsylvania
statutes, including the 18-year statute of limitations, that permit
paternity to be litigated more than six years after an illegitimate
child's birth; and by the fact that increasingly sophisticated
scientific tests facilitate the establishing of paternity
regardless of the child's age. Pp.

O'CONNOR, J., delivered the opinion for a unanimous Court.
JUSTICE O'CONNOR delivered the opinion of the Court.
Under Pennsylvania law, an illegitimate child must prove
paternity before seeking support from his or her father, and a suit
to establish paternity ordinarily must be brought within six years
of an illegitimate child's birth. By contrast, a legitimate child
may seek support from his or her parents at any time. We granted
certiorari to consider the constitutionality of this legislative
scheme.
I
On September 22, 1983, petitioner Cherlyn Clark filed a support
complaint in the Allegheny County Court of Common Pleas on behalf
of her minor daughter, Tiffany, who was born out of wedlock on June
11, 1973. Clark named respondent
Page 486 U. S. 458
Gene Jeter as Tiffany's father. The court ordered blood tests,
which showed a 99.3% probability that Jeter is Tiffany's
father.
Jeter moved to dismiss the complaint on the ground that it was
barred by the 6-year statute of limitations for paternity actions.
* In her response,
Clark contended that this statute is unconstitutional under the
Equal Protection and Due Process Clauses of the Fourteenth
Amendment. In the alternative, she argued that the statute was
tolled by fraudulent and misleading actions of the welfare
department, or by threats and assaults by Jeter.
The trial court upheld the statute of limitations on the
authority of
Astemborski v. Susmarski, 499 Pa. 99,
451 A.2d
1012 (1982),
vacated, 462 U.S. 1127 (1983),
reinstated on remand, 502 Pa. 409,
466
A.2d 1018 (1983). The Pennsylvania Supreme Court there had
considered and rejected constitutional challenges similar to
Clark's. The trial court also rejected Clark's argument that the
statute should be tolled, specifically finding that any fear that
Clark may have had of Jeter had subsided more than six years before
she filed her support complaint. Therefore, the trial court entered
judgment for Jeter.
Clark appealed to the Superior Court of Pennsylvania, again
raising her constitutional challenges to the 6-year statute of
limitations. Before the court decided her case, the
Page 486 U. S. 459
Pennsylvania Legislature enacted an 18-year statute of
limitations for actions to establish paternity. Act of Oct. 30,
1985, No. 66, § 1, subch. C, 1985 Pa. Laws 270,
codified
at 23 Pa.Cons.Stat. § 4343(b) (1985). Pennsylvania thereby
brought its law into compliance with a provision of the federal
Child Support Enforcement Amendments of 1984 that requires all
States participating in the federal child support program to have
procedures to establish the paternity of any child who is less than
18 years old. 98 Stat. 1307, 42 U.S.C. § 666(a)(5) (1982 ed., Supp.
IV). The Superior Court concluded, however, that Pennsylvania's new
18-year statute of limitations did not apply retroactively, and
that it would not revive Clark's cause of action in any event. 358
Pa.Super. 550,
518
A.2d 276 (1986). It affirmed the trial court's conclusions that
the 6-year statute of limitations was constitutional, and that
Clark's tolling argument was without merit. Thereafter, the
Superior Court denied Clark's motion for reargument. The
Pennsylvania Supreme Court denied her petition for allowance of
appeal. We granted Clark's petition for certiorari. 484 U.S. 1003
(1988).
II
Clark's first argument to this Court is that Pennsylvania's
6-year statute of limitations is invalid because it conflicts with
the federal Child Support Enforcement Amendments of 1984, which she
says require States to adopt retroactive 18-year statutes of
limitations in paternity cases.
See 42 U.S.C. § 666(a)(5)
(1982 ed., Supp. IV). Because this argument raises an issue of
statutory interpretation, we ordinarily would address it before
reaching the constitutional claims.
Blum v. Bacon,
457 U. S. 132,
457 U. S. 137
(1982);
see Townsend v. Swank, 404 U.
S. 282,
404 U. S. 285,
404 U. S. 291
(1971). Having reviewed the record, however, we find that Clark did
not adequately present a federal preemption argument to the lower
courts. It is our practice, when reviewing decisions by state
courts, not to decide federal claims that were not
Page 486 U. S. 460
"pressed or passed upon" below.
Bankers Life & Casualty
Co. v. Crenshaw, 486 U. S. 71,
486 U. S. 79-80
(1988).
The Pennsylvania Legislature passed the 18-year statute of
limitations on October 30, 1985. At that time, Clark already had
filed her brief on appeal to the Superior Court. Clark immediately
suggested a remand to determine the retroactivity of the new
Pennsylvania statute. But the Superior Court instead itself decided
that the 6-year statute of limitations would continue to apply to
cases like Clark's. The court reasoned that, under Pennsylvania
law, a statute is retroactive only if the legislature clearly and
manifestly so intends, and it found insufficient evidence of such
an intent. The decision did not address the relevance of the
federal Child Support Enforcement Amendments to the continuing
validity of the 6-year statute of limitations. 358 Pa.Super., at
553-555, 518 A.2d at 278.
In her application for reargument in the Superior Court and in
her petition for appeal to the Pennsylvania Supreme Court, Clark
argued that the Superior Court had overlooked Pennsylvania cases
which had applied similar statutes of limitations retroactively, as
well as indications that the federal Child Support Enforcement
Amendments required States to adopt retroactive 18-year statutes of
limitations or their equivalent.
See 42 U.S.C. § 666(a)(5)
(1982 ed., Supp. III); 50 Fed.Reg.19608, 19631 (1985). But Clark
did not expressly assert that the 6-year statute of limitations was
preempted by the new federal law. We interpret Clark's argument to
be that the Pennsylvania Legislature intended to comply with the
new conditions on the federal spending program, which arguably
showed that it clearly and manifestly intended its new statute to
be retroactive. This question of how to interpret the Pennsylvania
statute ultimately is a matter of state law. We find that Clark's
argument below was not adequate to raise a federal preemption
claim. Accordingly, we do not address it here, and proceed to her
equal protection claim.
Page 486 U. S. 461
In considering whether state legislation violates the Equal
Protection Clause of the Fourteenth Amendment, U.S.Const., Amdt.
14, § 1, we apply different levels of scrutiny to different types
of classifications. At a minimum, a statutory classification must
be rationally related to a legitimate governmental purpose.
San
Antonio Independent School Dist. v. Rodriguez, 411 U. S.
1,
411 U. S. 17
(1973);
cf. Lyng v. Automobile Workers, 485 U.
S. 360,
485 U. S. 370
(1988). Classifications based on race or national origin,
e.g., Loving v. Virginia, 388 U. S.
1,
388 U. S. 11
(1967), and classifications affecting fundamental rights,
e.g.,
Harper v. Virginia Bd. of Elections, 383 U.
S. 663,
383 U. S. 672
(1966), are given the most exacting scrutiny. Between these
extremes of rational basis review and strict scrutiny lies a level
of intermediate scrutiny, which generally has been applied to
discriminatory classifications based on sex or illegitimacy.
See, e.g., Mississippi University for Women v. Hogan,
458 U. S. 718,
458 U. S.
723-724, and n. 9 (1982);
Mills v. Habluetzel,
456 U. S. 91,
456 U. S. 99
(1982);
Craig v. Boren, 429 U. S. 190,
429 U. S. 197
(1976);
Mathews v. Lucas, 427 U.
S. 495,
427 U. S.
505-506 (1976).
To withstand intermediate scrutiny, a statutory classification
must be substantially related to an important governmental
objective. Consequently we have invalidated classifications that
burden illegitimate children for the sake of punishing the illicit
relations of their parents, because "visiting this condemnation on
the head of an infant is illogical and unjust."
Weber v. Aetna
Casualty & Surety Co., 406 U. S. 164,
406 U. S. 175
(1972). Yet, in the seminal case concerning the child's right to
support, this Court acknowledged that it might be appropriate to
treat illegitimate children differently in the support context
because of "lurking problems with respect to proof of paternity."
Gomez v. Perez, 409 U. S. 535,
409 U. S. 538
(1973).
This Court has developed a particular framework for evaluating
equal protection challenges to statutes of limitations
Page 486 U. S. 462
that apply to suits to establish paternity, and thereby limit
the ability of illegitimate children to obtain support.
"First, the period for obtaining support . . . must be
sufficiently long in duration to present a reasonable opportunity
for those with an interest in such children to assert claims on
their behalf. Second, any time limitation placed on that
opportunity must be substantially related to the State's interest
in avoiding the litigation of stale or fraudulent claims."
Mills v. Habluetzel, 456 U.S. at
456 U. S.
99-100.
In
Mills, we held that Texas' l-year statute of
limitations failed both steps of the analysis. We explained that
paternity suits typically will be brought by the child's mother,
who might not act swiftly amidst the emotional and financial
complications of the child's first year. And it is unlikely that
the lapse of a mere 12 months will result in the loss of evidence
or appreciably increase the likelihood of fraudulent claims.
Id. at
456 U. S.
100-101. A concurring opinion in
Mills
explained why statutes of limitations longer than one year also may
be unconstitutional.
Id. at
456 U. S.
102-106 (O'CONNOR, J., joined by Burger, C.J., and
BRENNAN and BLACKMUN, JJ., and joined as to Part I by Powell, J.,
concurring). First, the State has a countervailing interest in
ensuring that genuine claims for child support are satisfied.
Second, the fact that Texas tolled most other causes of action
during a child's minority suggested that proof problems do not
become overwhelming during this period. Finally, the practical
obstacles to filing a claim for support are likely to continue
after the first year of the child's life.
In
Pickett v. Brown, 462 U. S. 1 (1983),
the Court unanimously struck down Tennessee's 2-year statute of
limitations for paternity and child support actions brought on
behalf of certain illegitimate children. Adhering to the analysis
developed in
Mills, the Court first considered whether two
years afforded a reasonable opportunity to bring such suits. The
Tennessee statute was relatively more generous than the
Page 486 U. S. 463
Texas statute considered in
Mills, because it did not
limit actions against a father who had acknowledged his paternity
in writing or by furnishing support; nor did it apply if the child
was likely to become a public charge. Nevertheless, the Court
concluded that the 2-year period was too short in light of the
persisting financial and emotional problems that are likely to
afflict the child's mother. Proceeding to the second step of the
analysis, the Court decided that the 2-year statute of limitations
was not substantially related to Tennessee's asserted interest in
preventing stale and fraudulent claims. The period during which
suit could be brought was only a year longer than the period
considered in
Mills, and this incremental difference would
not create substantially greater proof and fraud problems.
Furthermore, Tennessee tolled most other actions during a child's
minority, and even permitted a support action to be brought on
behalf of a child up to 18 years of age if the child was or was
likely to become a public charge. Finally, scientific advances in
blood testing had alleviated some problems of proof in paternity
actions. For these reasons, the Tennessee statute failed to survive
heightened scrutiny under the Equal Protection Clause.
In light of this authority, we conclude that Pennsylvania's
6-year statute of limitations violates the Equal Protection Clause.
Even six years does not necessarily provide a reasonable
opportunity to assert a claim on behalf of an illegitimate
child.
"The unwillingness of the mother to file a paternity action on
behalf of her child, which could stem from her relationship with
the natural father or . . . from the emotional strain of having an
illegitimate child, or even from the desire to avoid community and
family disapproval, may continue years after the child is born. The
problem may be exacerbated if, as often happens, the mother herself
is a minor."
Mills, supra, at
456 U. S. 105,
n. 4 (O'CONNOR, J., concurring). Not all of these difficulties are
likely to abate in six years. A mother might realize only belatedly
"a loss of income attributable to the need to care for the child,"
Pickett,
Page 486 U. S.
464
supra, at 12. Furthermore, financial difficulties are
likely to increase as the child matures and incurs expenses for
clothing, school, and medical care.
See, e.g., Moore v.
McNamara, 40 Conn.Supp. 6, 11, 12, 478 A.2d 634, 637 (1984)
(invalidating a 3-year statute of limitations). Thus it is
questionable whether a State acts reasonably when it requires most
paternity and support actions to be brought within six years of an
illegitimate child's birth.
We do not rest our decision on this ground, however, for it is
not entirely evident that six years would necessarily be an
unreasonable limitations period for child support actions involving
illegitimate children. We are, however, confident that the 6-year
statute of limitations is not substantially related to
Pennsylvania's interest in avoiding the litigation of stale or
fraudulent claims. In a number of circumstances, Pennsylvania
permits the issue of paternity to be litigated more than six years
after the birth of an illegitimate child. The statute itself
permits a suit to be brought more than six years after the child's
birth if it is brought within two years of a support payment made
by the father. And in other types of suits, Pennsylvania places no
limits on when the issue of paternity may be litigated. For
example, the intestacy statute, 20 Pa.Cons.Stat. § 2107(3) (1982),
permits a child born out of wedlock to establish paternity as long
as "there is clear and convincing evidence that the man was the
father of the child." Likewise, no statute of limitations applies
to a father's action to establish paternity.
In re Mengel,
287 Pa.Super. 186,
429
A.2d 1162 (1981). Recently, the Pennsylvania Legislature
enacted a statute that tolls most other civil actions during a
child's minority. 42 Pa.Cons.Stat. § 5533(b) (Supp.1987). In
Pickett and
Mills, similar tolling statutes cast
doubt on the State's purported interest in avoiding the litigation
of stale or fraudulent claims. 462 U.S. at
462 U. S. 15-16;
456 U.S. at
456 U. S.
104-105 (O'CONNOR, J., concurring);
id. at
456 U. S. 106
(Powell, J., concurring in judgment). Pennsylvania's tolling
statute has the same implications here.
Page 486 U. S. 465
A more recent indication that Pennsylvania does not consider
proof problems insurmountable is the enactment by the Pennsylvania
Legislature in 1985 of an 18-year statute of limitations for
paternity and support actions. 23 Pa.Cons.Stat. § 4343(b) (1985).
To be sure, the legislature did not act spontaneously, but rather
under the threat of losing some federal funds. Nevertheless, the
new statute is a tacit concession that proof problems are not
overwhelming. The legislative history of the federal Child Support
Enforcement Amendments explains why Congress thought such statutes
of limitations are reasonable. Congress adverted to the problem of
stale and fraudulent claims, but recognized that increasingly
sophisticated tests for genetic markers permit the exclusion of
over 99% of those who might be accused of paternity, regardless of
the age of the child. H.R.Rep. No. 98-527, p. 38 (1983). This
scientific evidence is available throughout the child's minority,
and it is an additional reason to doubt that Pennsylvania had a
substantial reason for limiting the time within which paternity and
support actions could be brought.
We conclude that the Pennsylvania statute does not withstand
heightened scrutiny under the Equal Protection Clause. We therefore
find it unnecessary to reach Clark's due process claim. The
judgment of the Superior Court is reversed, and the case is
remanded for further proceedings not inconsistent with this
opinion.
It is so ordered.
* Although Jeter's motion referred to § 6704(e), that section
had been altered slightly and relabeled as § 6704(b) at the time of
the litigation below.
See Act of Dec. 20, 1982, No. 326,

child born out of wedlock brought under this section must be

support of the child or shall have acknowledged in writing his
paternity, in which case an action or proceeding may be commenced
at any time within two years of any such contribution or
acknowledgement by the reputed father." 42 Pa.Cons.Stat. § 6704(b)
