The Traditional Standard: Restrained Review.
The tradi-tional standard of review of equal protection challenges of classifications developed largely though not entirely in the context of economic regulation.1447 It is still most often applied there, although it appears in many other contexts as well,1448 including so-called “class-of-one” challenges.1449 A more active review has been developed for classifications based on a “suspect” indicium or affecting a “fundamental” interest. “The Fourteenth Amendment enjoins ‘the equal protection of the laws,’ and laws are not abstract propositions.” Justice Frankfurter once wrote, “They do not relate to abstract units, A, B, and C, but are expressions of policy arising out of specific difficulties, addressed to the attainment of specific ends by the use of specific remedies. The Constitution does not require things which are different in fact or opinion to be treated in law as though they were the same.”1450 Thus, the mere fact of classification will not void legislation,1451 because in the exercise of its powers a legislature has considerable discretion in recognizing the differences between and among persons and situations.1452 “Class legislation, discriminating against some and favoring others, is prohibited; but legislation which, in carrying out a public purpose, is limited in its application, if within the sphere of its operation it affects alike all persons similarly situated, is not within the amendment.”1453 Or, more succinctly, “statutes create many classifications which do not deny equal protection; it is only ‘invidious discrimination’ which offends the Constitution.”1454
How then is the line between permissible and invidious classification to be determined? In Lindsley v. Natural Carbonic Gas Co.,1455 the Court summarized one version of the rules still prevailing. “1. The equal protection clause of the Fourteenth Amendment does not take from the State the power to classify in the adoption of police laws, but admits of the exercise of a wide scope of discretion in that regard, and avoids what is done only when it is without any reasonable basis and therefore is purely arbitrary. 2. A classification having some reasonable basis does not offend against that clause merely because it is not made with mathematical nicety or because in practice it results in some inequality. 3. When the classification in such a law is called in question, if any state of facts reasonably can be conceived that would sustain it, the existence of that state of facts at the time the law was enacted must be assumed. 4. One who assails the classification in such a law must carry the burden of showing that it does not rest upon any reasonable basis, but is essentially arbitrary.” Especially because of the emphasis upon the necessity for total arbitrariness, utter irrationality, and the fact that the Court will strain to conceive of a set of facts that will justify the classification, the test is extremely lenient and, assuming the existence of a constitutionally permissible goal, no classification will ever be upset. But, contemporaneously with this test, the Court also pronounced another lenient standard which did leave to the courts a judgmental role. In F.S. Royster Guano Co. v. Virginia,1456 the court put forward the following test: “[T]he classification must be reasonable, not arbitrary, and must rest upon some ground of difference having a fair and substantial relation to the object of the legislation, so that all persons similarly circumstanced shall be treated alike.”1457 Use of the latter standard did in fact result in some in-validations.1458
But then, coincident with the demise of substantive due process in the area of economic regulation,1459 the Court reverted to the former standard, deferring to the legislative judgment on questions of economics and related matters; even when an impermissible purpose could have been attributed to the classifiers it was usually possible to conceive of a reason that would justify the classification.1460 Strengthening the deference was the recognition of discretion in the legislature not to try to deal with an evil or a class of evils all within the scope of one enactment but to approach the problem piecemeal, to learn from experience, and to ameliorate the harmful results of two evils differently, resulting in permissible over-and under-inclusive classifications.1461
In recent years, the Court has been remarkably inconsistent in setting forth the standard which it is using, and the results have reflected this. It has upheld economic classifications that suggested impermissible intention to discriminate, reciting at length the Lindsley standard, complete with the conceiving-of-a-basis and the one-step-at-a-time rationale,1462 and it has applied this relaxed standard to social welfare regulations.1463 In other cases, it has used the Royster Guano standard and has looked to the actual goal articulated by the legislature in determining whether the classification had a reasonable relationship to that goal,1464 although it has usually ended up upholding the classification. Finally, purportedly applying the rational basis test, the Court has invalidated some classifications in the areas traditionally most subject to total deference.1465
Attempts to develop a consistent principle have so far been unsuccessful. In Railroad Retirement Board v. Fritz,1466 the Court acknowledged that “[t]he most arrogant legal scholar would not claim that all of these cases cited applied a uniform or consistent test under equal protection principles,” but then went on to note the differences between Lindsley and Royster Guano and chose the former. But, shortly, in Schweiker v. Wilson,1467 in an opinion written by a different Justice,1468 the Court sustained another classification, using the Royster Guano standard to evaluate whether the classification bore a substantial relationship to the goal actually chosen and articulated by Congress. In between these decisions, the Court approved a state classification after satisfying itself that the legislature had pursued a permissible goal, but setting aside the decision of the state court that the classification would not promote that goal; the Court announced that it was irrelevant whether in fact the goal would be promoted, the question instead being whether the legislature “could rationally have decided” that it would.1469
In short, it is uncertain which formulation of the rational basis standard the Court will adhere to.1470 In the main, the issues in recent years have not involved the validity of classifications, but rather the care with which the Court has reviewed the facts and the legislation with its legislative history to uphold the challenged classifications. The recent decisions voiding classifications have not clearly set out which standard they have been using.1471 Clarity in this area, then, must await presentation to the Court of a classification that it would sustain under the Lindsley standard and invalidate under Royster Guano.

- Vacco v. Quill, 521 U.S. 793 (1997) (assisted suicide prohibition does not violate Equal Protection Clause by distinguishing between terminally ill patients on life-support systems who are allowed to direct the removal of such systems and patients who are not on life support systems and are not allowed to hasten death by self-administering prescribed drugs).
- The Supreme Court has recognized successful equal protection claims brought by a class-of-one, where a plaintiff alleges that she has been intentionally treated differently from others similarly situated and that there is no rational basis for that difference. Village of Willowbrook v. Olech, 528 U.S. 562, 564 (2000) (per curiam) (village’s demand for an easement as a condition of connecting the plaintiff ’s property to the municipal water supply was irrational and wholly arbitrary). However, the class-of-one theory, which applies with respect to legislative and regulatory action, does not apply in the public employment context. Engquist v. Oregon Department of Agriculture, 128 S. Ct. 2146, 2149 (2008) (allegation that plaintiff was fired not because she was a member of an identified class but simply for “arbitrary, vindictive, and malicious reasons” does not state an equal protection claim). In Engquist, the Court noted that “the government as employer indeed has far broader powers than does the government as sovereign,” id. at 2151 (quoting Waters v. Churchill, 511 U.S. 661, 671 (1994), and that it is a “common-sense realization” that government offices could not function if every employment decision became a constitutional matter. Id. at 2151, 2156.

- 220 U.S. 61, 78–79 (1911), quoted in full in Morey v. Doud, 354 U.S. 457, 463–64 (1957). Classifications which are purposefully discriminatory fall before the Equal Protection Clause without more. E.g., Barbier v. Connolly, 113 U.S. 27, 30 (1885); Yick Wo v. Hopkins, 118 U.S. 356, 373–74 (1886). Cf. New York City Transit Auth. v. Beazer, 440 U.S. 568, 593 n.40 (1979). Explicit in all the formulations is that a legislature must have had a permissible purpose, a requirement which is seldom failed, given the leniency of judicial review. But see Zobel v. Williams, 457 U.S. 55, 63–64 (1982), and id. at 65 (Justice Brennan concurring).

- In Nebbia v. New York, 291 U.S. 502, 537 (1934), speaking of the limits of the Due Process Clause, the Court observed that “in the absence of other constitutional restrictions, a state is free to adopt whatever economic policy may reasonably be deemed to promote public welfare.”

It is significant that these opinions were written by Justices who subsequently dissented from more relaxed standard of review cases and urged adherence to at least a standard requiring articulation of the goals sought to be achieved and an evaluation of the “fit” of the relationship between goal and classification. Railroad Retirement Bd. v. Fritz, 449 U.S. 166, 182 (1980) (Justices Brennan and Marshall dissenting); Schweiker v. Wilson, 450 U.S. 221, 239 (1981) (Justices Powell, Brennan, Marshall, and Stevens dissenting). See also New York City Transit Auth. v. Beazer, 440 U.S. 568, 594 (1979) (Justice Powell concurring in part and dissenting in part), and id. at 597, 602 (Justices White and Marshall dissenting).
- E.g., Lindsey v.

Cleburne Living Center, 473 U.S. 432 (1985) (rejecting various justifications offered for exclusion of a home for the mentally retarded in an area where boarding homes, nursing and convalescent homes, and fraternity or sorority houses were permitted). The Court in Reed v. Reed, 404 U.S. 71, 76 (1971), used the Royster Guano formulation and purported to strike down a sex classification on the rational basis standard, but, whether the standard was actually used or not, the case was the beginning of the decisions applying a higher standard to sex classifications.
- 449 U.S. 166, 174–79 (1980). The quotation is at 176–77 n.10. The extent of deference is notable, inasmuch as the legislative history seemed clearly to establish that the purpose the Court purported to discern as the basis for the classification was not the congressional purpose at all. Id. at 186–97 (Justice Brennan dissenting). The Court observed, however, that it was “constitutionally irrelevant” whether the plausible basis was in fact within Congress’s reasoning, inasmuch as the Court has never required a legislature to articulate its reasons for enactng a statute. Id. at 179. For a continuation of the debate over actual purpose and conceivable justification, see Kassel v. Consolidated Freightways Corp., 450 U.S. 662, 680–85 (1981) (Justice Brennan concurring), and id. at 702–06 (Justice Rehnquist dissenting). Cf. Schweiker v. Wilson, 450 U.S. 221, 243–45 (1981) (Justice Powell dissenting).
- 450 U.S. 221, 230–39 (1981). Nonetheless, the four dissenters thought that the purpose discerned by the Court was not the actual purpose, that it had in fact no purpose in mind, and that the classification was not rational. Id. at 239.
- Justice Blackmun wrote the Court’s opinion in Wilson, Justice Rehnquist in Fritz.
- Minnesota v. Clover Leaf Creamery Co., 449 U.S. 456, 461–70 (1981). The quoted phrase is at 466.
- In City of Mesquite v. Aladdin’s Castle, Inc., 455 U.S. 283 (1982), the Court observed that it was not clear whether it would apply Royster Guano to the classification at issue, citing Fritz as well as Craig v. Boren, 429 U.S. 190 (1976), an intermediate standard case involving gender. Justice Powell denied that Royster Guano or Reed v. Reed had ever been rejected. Id. at 301 n.6 (dissenting). See also id. at 296–97 (Justice White).
- The exception is Reed v. Reed, 404 U.S. 71 (1971), which, though it purported to apply Royster Guano, may have applied heightened scrutiny. See Zobel v. Williams, 457 U.S. 55, 61–63 (1982), in which the Court found the classifications not rationally related to the goals, without discussing which standard it was using.
