Judges striking labor laws were not always careful to distinguish opposition to class legislation from protection of fundamental liberties. Cushman maintains that the principle of neutrality formed the principal strand in substantive due process jurisprudence, but nevertheless stresses “the error in attempting to identify … a single animating principle for a body of constitutional law composed by scores of decisions handed down over more than four decades, and involving more than two dozen Justices.” “Varieties and Vicissitudes,” 941.

A significant ambiguity characterized free labor ideology. In the early decades of the new republic, economic opportunity meant the prospect of rising to self-employment, establishing oneself as an independent producer. This prospect was already receding on the eve of the Civil War. “This does not mean,” writes Foner, “that industrialization and mechanized agriculture ended social mobility—on the contrary, the evidence is that they expanded it. But the mobility of the age of the independent producer, whose aspiration was economic self-sufficiency, was superseded by the mobility of industrial society, in which workers could look forward to a rising standard of living.” Ibid., 33.

Nourse offers a convincing explanation of the discrepancy between the judiciary's increasing receptivity to progressive legislation and contemporary reformers' hostility to the courts. The chief source of this hostility was not the progressive legal community, where a more nuanced view of the judiciary prevailed, but rather Theodore Roosevelt's politics. Roosevelt was engaged in building a political movement, and castigated Court decisions such as Lochner as part of a call to arms predicated on drawing a sharp contrast between progressivism and conservative reaction. He continued to demonize the judiciary even after conceding that Lochner had become a dead letter. Nourse, “A Tale of Two Lochners,” 751–99. See also Milkis, Sidney M. and Tichenor, Daniel J., “‘Direct Democracy’ and Social Justice: The Progressive Party Campaign of 1912,” Studies in American Political Development 8 (1994): 282–340CrossRefGoogle Scholar. Nourse's analysis also reminds us that legal and political narratives obey distinct dynamics. This is not to say that courts operate in a political vacuum. Rather, legal discourse has its own internal logic that cannot be reduced to politics; nor can legal change be explained simply as a reflection of political pressures. See Gillman, The Constitution Besieged, 15–18, for an excellent statement of this view.

18. Bernstein, Rehabilitating Lochner, 14–22; and Phillips, The Lochner Court, 105–19. See also Mayer, Liberty of Contract, 30–32, 63–67. Bernstein and Phillips do recognize that the judiciary's presumption in favor of liberty was rebuttable, by showing that legislation was genuinely intended to protect weaker parties from economic exploitation. Bernstein, Rehabilitating Lochner, 48–53; and Phillips, The Lochner Court, 57, 128–29, 137–39. They do not explain why judges concerned to protect contractual liberty routinely authorized the use of state power to redress the effects of workers' bargaining disadvantage.

20. I do not address the legal controversy over workers' compensation statutes and laws prohibiting so-called yellow dog contracts, requiring workers to disassociate themselves from unions as a condition of employment. Although conflicting views of the market's fairness play a central role in these cases, they are complicated by special considerations and merit separate treatment. The constitutionality of compensation statutes involved the evolution of tort doctrine, from traditional to probabilistic conceptions of causation pioneered by the new science of accident statistics. See Witt, John Fabian, The Accidental Republic, Crippled Workingmen, Destitute Widows, and the Remaking of American Law (Cambridge, MA: Harvard University Press, 2004), 126–207CrossRefGoogle Scholar. The validity of statutes protecting labor unions required courts to reconcile contractual liberty with liberty of association. See Cushman, Rethinking the New Deal Court, 107–38.

21. Historians generally agree that West Coast v. Parrish, 300 U.S. 379 (1937), concluded this period of constitutional jurisprudence. There is less agreement about its starting-point. I chose the mid-1880s because Godcharles v. Wigeman, 113 Pa. 431 (1886) and Millett v. People, 117 Ill. 294 (1886) were the first decisions to strike employment legislation on substantive due process grounds. See Pound, “Liberty of Contract,” 455, 471.

22. Gillman, The Constitution Besieged, 190. See also Fiss, Troubled Beginnings, 7–8; Horwitz, The Transformation of American Law, 7.

Cachán rightly points out that “free labor” ideology was only one ingredient in Field's Slaughter-House dissent; an equally important component was “its ideological corollary, laissez-faire.” Ibid., 567. However, there was no tension between free labor and laissez-faire principles as long the market distributed opportunity fairly. The rift between them opened by the third quarter of the nineteenth century, when deepening economic inequalities undercut the claim that market ordering offered an equal opportunity to rise. In these changed circumstances, Field's continuing commitment to laissez-faire rendered his jurisprudence increasingly conservative.

44. The two pioneering cases are Godcharles v. Wigeman, 113 Pa. 431 (1886), in which Pennsylvania's Supreme Court invalidated an act regulating wage payment in the mining industry, and Millet v. People, 117 Ill. 294 (1886), in which the Supreme Court of Illinois struck a similar law. For state court decisions striking time and manner of wage payment regulations, see also State v. Goodwill, 33 W. Va. 179 (1889); Commonwealth v. Perry, 155 Mass. 117 (1891); Frorer v. People, 141 Ill. 171 (1892); State v. Loomis, 115 Mo. 307 (1893); Johnson v.

Not surprisingly, scholarly discussions of the judiciary's hostility to wage regulation normally begin here, but they generally neglect the line of cases, beginning at the turn of the century, in which state courts rejected due process attacks on time and manner of payment laws. These cases are largely ignored by Gillman, The Constitution Besieged; McCurdy, “The ‘Liberty of Contract’ Regime in American Law;” Horwitz, The Transformation of American Law; Forbath, “The Ambiguities of Free Labor;” and Sunstein, “Lochner's Legacy.” They are, however, an important first test of the courts' willingness to sustain government intervention in wage negotiations.

The grounds of the decisions were at first restricted to the states' authority to amend or repeal acts of incorporation in the public interest. They did not extend to natural persons. The states' authority was not unlimited, however, and courts faced the question whether changes in corporate charters satisfied substantive due process. See, for example, Leep v. Railway Co., 58 Ark. 407 (1894), striking an Arkansas act requiring wage payment on the day of discharge for natural persons, but sustaining the statute for corporations. By the end of the century, however, many state courts eliminated the distinction between licensed corporations and natural persons. There were successful challenges to statutes regulating time and manner of wage payment after 1900, but they became increasingly rare: see Republic Iron & Steel Co. v. State, 160 Ind. 379 (1903); State v. Missouri Tie & Timber Co., 181 Mo. 536 (1904); Kellyville Coal Co. v. Harrier, 207 Ill. 624 (1904); Jordon v. State, 103 S.W. 633 (1907); and State v. Potomac Valley Coal Co., 116 Md. 380 (1911).

51. In addition to the cases discussed pp. 14–20, the following state court cases sustained time and manner of payment laws. For statutes requiring payment in legal money, see Dayton Coal & Iron v. Barton, 103 Tenn. 604 (1899); Johnson Lyttle & Co. v. Spartan Mills, 68 S.C. 339 (1904); Regan v. Tremont Lumber Co., 134 La. 199 (1914); and Atkins v. Grey Eagle Coal Co., 76 W. Va. 27 (1915).

55. Ibid., 440. Caldwell approvingly cited the language of the United States Supreme Court in Holden v. Hardy, 169 U.S. 366 (1898), acknowledging that workers suffered from disparities in bargaining power that made them especially susceptible to employer overreaching. Ibid., 444. He also drew on Holden to underscore the irony in the claim, offered by counsel for the employer, that the law “violated his right to contract as he pleased. To that contention the Court aptly replied: ‘The argument would certainly come with better grace and greater cogency from the latter class.’” Ibid., 445. Two state appellate courts also cited Holden's finding that workers were economically vulnerable. See Kansas v. Wilson, 7 Kan. App. 428 (1898), 436–37, sustaining a statute regulating the weighing of coal, and New York Central and Hudson River Railroad Co. v. Williams, 64 Misc. 15 (1909), 28–29, upholding a law requiring semimonthly payment in cash. Both cases were affirmed on appeal by the states' high courts: State v. Wilson, 61 Kan. 32 (1899); and New York Central and Hudson River Railroad Co. v. Williams, 199 N.Y. 108 (1910). Holden's influence on rulings on labor legislation is discussed, pp. 22–26.

See, also, the Supreme Court's ruling in Mutual Loan Co. v. Martell, 222 U.S. 225 (1911), sustaining a Massachusetts law prohibiting wage assignments. Both cases stressed the need to protect wage workers from being taken advantage of by unscrupulous lenders.

61. Shorthall v. Puget Sound Bridge Co., 45 Wash. 290 (1907), 294–95. “Acts of this nature,” concluded the Court, “have been passed by the majority of the states of the Union, and are supported by the great weight of the decisions of the state courts and by the supreme court of the United States.” The court appealed to a number of authorities, including State v. Peel Splint Coal Co. (1892); State v. Brown & Sharpe Mfg. Co. (1892); St. Louis, Iron Mountain & Southern Railway Co. v. Paul (1897); Harbison v. Knoxville Iron Co. (1899); Opinion of the Justices (1895); St. Louis, Iron Mountain and St. Paul Railway Co. (1899); and Knoxville Iron Co. v. Harbison (1901).

62. State v. Missouri Pacific, 242 Mo. 339 (1912), 360. The Missouri court's conclusion is also worth noting: “By common consent, in all civilized communities, an implied duty rests upon the State to aid those unfortunates who through sickness, old age, extreme poverty or other mischance are unable to supply themselves with those things which are necessary for their continued existence, and consequently any law which encourages people to work by holding out assurances that they shall promptly receive the wages they may earn … tends to encourage honest effort, and helps to build up an industrious, thrifty and self-respecting people, who, instead of becoming paupers, will be able to pay their debts, and being protected by the State in their efforts to better their condition, will have a direct interest in maintaining their protector, and in its good order, morals and general welfare.” Ibid., 376.

63. St. Louis, Iron Mountain and St. Paul Railway v. Paul, 173 U.S. 404. See St. Louis, Iron Mountain & Southern Railway Co. v. Paul, 64 Ark. 83 (1897). The Supreme Court, like the Arkansas court, sustained the law only as it affected corporations, under the state's authority to amend corporate charters; the law was held unconstitutional as it affected natural persons. Railroads were also firms clothed with a public interest, having special duties to the public. The state still faced the burden of showing that the corporate charter was amended for legitimate public aims, to correct an evil that had proven injurious to the public interest.

Yaple, 236 U.S. 338 (1915), 345, the high court quoted a report by the Ohio Coal Mining Commission explaining why the screen system “was regarded as objectionable to the miners:” “they were not paid for mining a considerable quantity of marketable coal, and there was dissatisfaction because of the wearing of the screens so as to increase the size of the apertures between the bars above the standard.”

71. Ibid., 550. These three cases were decided by a 7–2 majority, with Brewer and Peckham, the two more conservative Justices, dissenting without comment. St. Louis, Knoxville, Dayton and McLean were the main precedents for four time and manner of payment decisions, all unanimous, from the second decade of the twentieth century: Mutual Loan Company v. Martell, 222 U.S. 225 (1911), preventing a loan company from enforcing an assignment of future wages; Erie Railroad Company v. Williams, 233 U.S. 685 (1914), requiring a railroad company to pay its employees every 2 weeks; Keokee Consolidated Coke Co. v. Taylor, 234 U.S. 224 (1914), requiring payment in lawful money; and Rail & River Coal Co. v. Yaple, 236 U.S. 238 (1915), denying injunctive relief to a company from an order by the Ohio industrial commission prohibiting the use of screens in weighing coal for the purpose of determining wages.

72. Two characteristics define hard bargains: a normative standard of fairness, establishing what the parties to an exchange are due, and a disadvantaged party, whose vulnerability renders it exploitable, so that the other party gains undeservedly at its expense.

93. Ibid., 394. The constitutionality of workplace safety laws was fully accepted even by the most libertarian judges, who normally rejected regulation of the employment contract. Thus, striking a maximum hours law for women, Justice Magruder distinguished those sections of the law mandating sanitary conditions in the workshops, with which he had no quarrel, from the hours provisions, on the grounds that work in the garment industry was not particularly dangerous and that women, unlike the “necessitous borrower,” do not lack the competence to make judgments about their own hours of work. Ritchie v. People, 155 Ill. 98 (1895), 106, 111–13. A decade later, Justice Peckham, writing the majority opinion in Lochner (discussed, pp. 28–31), accepted the constitutionality of the bakeshop act's provisions dealing with health and safety.  He did not see those provisions as inconsistent with free labor assumptions.  When it came to the statute's hours provisions, however, he distinguished the instant case from Holden and Knoxville on the grounds that baking was not particularly unhealthful and that bakers, unlike miners, were not economically disadvantaged.

96. Courts distinguished laws regulating sailors, borrowers and minors, which had been upheld, from laws regulating the employment contract of adult males, which they struck, on the ground that the former suffered from traditional incapacities known to the common law, whereas adult male workers were fully capable of protecting themselves. See Millett v. People (1886), 302–3; State v. Fire Creek Coal & Co. (1889), 190; State v. Goodwill (1889), 186; Frorer v. People (1892), 185–86; State v. Loomis (1892), 315–16; Braceville Coal Co. v.

106. Ibid., 333. A series of state cases in the early years of the century sustained maximum hours acts against due process attacks. They justified protective legislation, offering broad statements of the human harms of overwork, and acknowledging that inequalities between employers and wage workers explained why workers were unable to protect themselves. These courts moved cautiously to extend the reach of hours laws; they were limited to specific occupations or to a day of rest in the workweek. See Ex parte Kair, 28 Nev. 127 (1905); State v. Cantwell, 179 Mo. 245 (1904), affirmed per curiam by the United States Supreme Court in Cantwell v. Missouri, 199 U.S. 602 (1905); State v. Livingston Concrete Bldg. & Mfg.

107. The case was first appealed to a New York Appellate Division court, where the judges, in People v. Lochner, 73 A.D. 120 (N.Y. App. Div. 1902), voted 3–2 to sustain the law. The New York Court of Appeals, in People v. Lochner, 177 N.Y. 145 (1904), split 4–3 to uphold.

111. Ibid., 61–2. Bernstein maintains that the hours provision of the bakeshop act was a product of interest group conflict rather than a neutral health law. It represented a political agreement between the larger bakeries and organized workers to drive smaller proprietors employing nonunionized workers out of business. See Rehabilitating Lochner, 24–30. This argument fails to account for the financial burden on the smaller proprietors of implementing the sanitary provisions of the act. Would not the capital outlays required to satisfy sanitary regulations also bankrupt small bakeries? See Kens, Paul, Lochner v. New York, Economic Regulation on Trial (Lawrence: University Press of Kansas, 1998)Google Scholar, for an alternative account of the bakeshop act's enactment.

113. The Court's 5–4 ruling was a surprise. Bernstein, Rehabilitating Lochner, 33; Gillman, The Constitution Besieged, 251–52, n. 54. It was also a very close call: it seems that Justice Peckham's majority opinion was originally written in dissent, and Justice Harlan's dissent was the majority opinion. “Whether one of the justices … switched his vote … and if so why, remains a mystery.” Bernstein, Rehabilitating Lochner, 146, n. 110. Scholars have also puzzled over the reasons that may have persuaded Justices Brown and McKenna, normally willing to give the police power wider latitude, to join the majority. See Bernstein, Rehabilitating Lochner, 33; Cushman, “Varieties and Vicissitudes,” 930–33; and Siegel, “Lochner Era Jurisprudence,” 16–18.

119. Ibid., 57. Peckham's concession to workers' negotiating weakness was somewhat strained. He characterized Holden to say that Utah's miners were constrained by “the kind of employment, mining, smelting, etc., and the character of the employees in such kinds of labor,” to accept “the rules laid down by the proprietors in regard to labor.” In Knoxville, Tennessee's miners and coal workers were said to “be at a disadvantage with the employer in matters of wages, they being miners and coal workers.” Harlan's dissent made it clear that, in justifying the hours law,the Court's minority referred to workers' economic weakness.

124. Harlan refused to consider the consequences of shifting the burden of proof for the validity of general hours legislation: “it must be remembered that this statute does not apply to all kinds of business. It applies only to work in bakery and confectionery establishments.” Lochner v. New York, 70.

125. Holmes's dissent, normally celebrated for its progressive tenets, would have virtually abandoned judicial review. On his view, the Court must defer to legislatures “unless it can be said that a rational and fair man necessarily would admit that the statute proposed would infringe fundamental principles as they have been understood by the traditions of our people and our law.” Whether a statute “would be open to the charge of inequality I think it unnecessary to discuss.” Lochner v. New York, 76. Ironically, it was Holmes, rather than his colleagues, who held a Darwinian understanding of social conflict.

The Oregon court also appealed to the negative externalities of working dangerously long hours: “it was in the legislative mind that the regular employment of persons for longer hours in factories where different kinds of machinery and facilities are operated under the present day high-pressure power would tend to increase the danger of accidents, and to a greater extent jeopardize life and limb, thereby increasing the demand for compensation for such injuries, a portion of which, under certain circumstances, would ultimately be borne by the state.” State v.

133. “McKenna simply assumed that maximum-hour laws were as valid in their general application to male workers, regardless of whether a particular occupation was especially hazardous or wearing, as to female workers. That might have seemed a considerable leap some years earlier, but it was not by now.” Bickel and Schmidt, The Judiciary and Responsible Government, 601. Four members of the Lochner majority—Justices Peckham, Brewer, Fuller, and Brown—had left the Court by the time Bunting was decided. Justice McKenna remained on the Court, voting with the majority in Lochner and writing the majority opinion in Bunting. Cushman suggests that McKenna opposed New York's law as class legislation because it applied only to bakers, an infirmity that did not affect Oregon's law, covering industrial workers. “Varieties and Vicissitudes,” 937. Bickel and Schmidt, The Judiciary and Responsible Government, 39, 285, offer a more critical view of the “erratic” McKenna.

Persons's study of women's wages covered workers in “trade and transportation … manufacturing, and … certain groups in the domestic field.” The “term minimum wage,” he explains, “is, in a sense, a misnomer, since our legislation has defined a reasonable living wage rather than the bare minimum necessary to eke out a comfortless existence. Of the eight states [with minimum wage laws in 1913], excluding Utah's flat rate, all are practically in line with California's statute, which declares that it should be ‘not less than a wage adequate to supply to such women and minors the necessary cost of proper living and to maintain their health and welfare.’” Ibid.

156. Stettler v. O'Hara, 243 U.S. 629 (1917). The Court was closely divided over the constitutionality of the minimum wage. The justices first heard this case in the October term of 1914, and the decision went against the statute, but it was never delivered, perhaps because the majority was fragile. The case was reargued in 1916. By this time, Justice Lamar had died and Justice Hughes had retired, replaced by Justices Clarke and Brandeis. Clarke voted to affirm the law; therefore, it would have been sustained had Wilson appointed a Justice other than Brandeis, who was sympathetic to minimum wage laws. See Bickel and Schmidt, The Judiciary and Responsible Government, 593–603. The validity of the minimum wage remained a close call throughout this period. Cushman maintains that its constitutionality was “a position that had been taken by five justices in 1917 and again in 1923 by four justices of the Taft Court, including the chief justice himself. After Justice Stone replaced Justice McKenna in 1925, it was probably consistently the view of a majority of the justices on the Court.” “Varieties and Vicissitudes,” 997.

An examination of the decisions of this Court in which price regulation has been upheld will disclose that the element common to all is the existence of a situation or a combination of circumstances materially restricting the regulative force of competition, so that buyers or sellers are placed at such a disadvantage in the bargaining struggle that serious economic consequences result to a very large number of members of the community.”

See Cushman's excellent discussion of the internal dynamics of the Court as the Justices wrestled with the complex procedural and doctrinal issues involved, concluding that Roberts's decision to join the Parrish majority cannot be characterized as surrender to public pressure.
