Origins

The causes of the Lochner era have been the subject of debate. Michael J. Lindsay, writing in the Harvard Law Review
Harvard Law Review

, recounts the longstanding "progressive" view which became dominant in the decades following the New Deal:

According to progressive scholars, American judges steeped in laissez-faire economic theory, who identified with the nation’s capitalist class and harbored contempt for any effort to redistribute wealth or otherwise meddle with the private marketplace, acted on their own economic and political biases to strike down legislation that threatened to burden corporations or disturb the existing economic hierarchy. In order to mask this fit of legally unjustified, intellectually dishonest judicial activism, the progressive interpretation runs, judges invented novel economic “rights” — most notably “substantive due process” and “liberty of contract” — that they engrafted upon the Due Process Clause of the Fourteenth Amendment.


Cass R. Sunstein, in an influential essay from 1987, describes the Lochner era as the result of a Court which believed market ordering under common law
Common law
Common law is law developed by judges through decisions of courts and similar tribunals rather than through legislative statutes or executive branch action...

 to be part of nature rather than a legal construct and sought to preserve natural distribution of wealth against redistributive regulations:

The Lochner Court required government neutrality and was skeptical of government “intervention”; it defined both notions in terms of whether the state had threatened to alter the common law distribution of entitlements and wealth, which was taken to be a part of nature rather than a legal construct. Once the common law system came to be seen as a product of legal rules, the baseline from which constitutional decisions were made had to shift. When the Lochner framework was abandoned in West Coast Hotel, the common law system itself appeared to be a subsidy to employers. The West Coast Hotel Court thus adopted an alternative baseline and rejected Lochner era understandings of neutrality and action.


Howard Gillman, in the book The Constitution Besieged: The Rise & Demise of Lochner Era Police Powers Jurisprudence, argues that the decisions of the era can be understood as adhering to a constitutional tradition rooted in the Founding Fathers
Founding Fathers of the United States

' conception of appropriate and inappropriate policymaking in a commercial republic. A central tenet of this tradition was that government should not exhibit favoritism or hostility toward market competitors (referred to as "class legislation", which Gillman equates with the modern notion of special interests

 in a neutral manner so as not to benefit one class over another. This would make for a faction free republic, with the underlying assumption that the American economy could provide for all citizens and social dependency as had been observed in Europe could be avoided. These ideas, according to Gillman, had been inherited by the Lochnerian judges, whose jurisprudence reflected a good faith attempt to preserve a tradition that was increasingly being undermined by changing industrial relations in the United States.

This view has been criticized by David E. Bernstein, who claims that Gillman overstates the importance of class legislation on the jurisprudence. Bernstein has also criticized Sunstein's thesis, arguing in part that the notion of a common law baseline runs counter to numerous decisions in which the Court upheld statutory replacements of common law rules, notably in the field of workers' compensation
Workers' compensation
Workers' compensation is a form of insurance providing wage replacement and medical benefits to employees injured in the course of employment in exchange for mandatory relinquishment of the employee's right to sue his or her employer for the tort of negligence...

. Bernstein's view is that the Lochner era demonstrates "the Justices' belief that Americans had fundamental unenumerated constitutional rights" which were protected by the due process clause of the Fourteenth Amendment. In discovering these rights, "[t]he Justices had a generally historicist outlook, seeking to discover the content of fundamental rights through an understanding of which rights had created and advanced liberty among the Anglo-American people."

Jurisprudence

 clauses (excluding civil rights cases), and another 25 were struck down in reference to the due process clause coupled with some other provision. The Court's interpretation of the due process clause during the Lochner era has been dubbed in contemporary scholarship as "economic substantive due process". This doctrine can be divided into three elements:
  • 1. The due process clauses of the Fifth

  • 2. These liberties are not absolute and can be regulated for a limited set of purposes, including the "safety, health, morals, and general welfare of the public."

  • 3. The Court may examine legislation in order to ensure that the means used by the legislature to further its legitimate purposes are well-designed to achieve those purposes and not unduly restrictive of market choices.


In addition, the Court limited the power of the federal government under the Commerce Clause

, were decided during the Lochner era. Michael J. Phillips writes that "due largely to their 'familial' nature, these two cases helped legitimize the modern substantive due process decisions creating the constitutional right to privacy."

Beginning

The case of Mugler v. Kansas
Mugler v. Kansas
Mugler v. Kansas, , was an important United States Supreme Court case in which the 8 to 1 majority opinion of Associate Justice John Marshall Harlan—and the lone, partial dissent by Associate Justice Stephen J. Field—laid the foundation for the U.S...

 (1887) is often regarded as precursor to the Lochner era and the doctrine of economic substantive due process. Mugler had been convicted of violating a Kansas statute prohibiting the manufacture and sale of alcohol. He argued in part that the statute was unconstitutional under the due process clause of the Fourteenth Amendment. The Court affirmed the conviction, but stated its willingness to review the legitimacy of a state using its police power as potentially incompatible with substantive rights guaranteed by the due process clause:
If, therefore, a statute purporting to have been enacted to protect the public health, the public morals, or the public safety has no real or substantial relation to those objects, or is a palpable invasion of rights secured by the fundamental law, it is the duty of the courts to so adjudge, and thereby give effect to the Constitution.


The Court first held that the due process clause of the Fourteenth Amendment protected an individual's "liberty to contract" in the 1897 case of Allgeyer v. Louisiana
Allgeyer v. Louisiana
Allgeyer v. Louisiana, , was a landmark United States Supreme Court case in which a unanimous court struck down a Louisiana statute on grounds that it violated an individual's "liberty to contract." This was the first case in which the Supreme Court interpreted the word liberty in the Due Process...

. In a unanimous opinion, the Court stated that Fourteenth Amendment liberty includes:
(...) the right of the citizen to be free in the enjoyment of all his faculties; to be free to use them in all lawful ways; to live and work where he will; to earn his livelihood by any lawful calling; to pursue any livelihood or avocation; and for that purpose to enter into all contracts which may be proper, necessary and essential to his carrying out to a successful conclusion the purposes above mentioned.


In the era's namesake case of Lochner v. New York
Lochner v. New York
Lochner vs. New York, , was a landmark United States Supreme Court case that held a "liberty of contract" was implicit in the due process clause of the Fourteenth Amendment. The case involved a New York law that limited the number of hours that a baker could work each day to ten, and limited the...

 (1905), the Court struck down a New York State law limiting the number of hours bakers could work on the grounds that it violated the bakers' "right to contract". In the majority opinion in Lochner, Justice Rufus Peckham stated:
In every case that comes before this court, therefore, where legislation of this character is concerned and where the protection of the Federal Constitution is sought, the question necessarily arises: Is this a fair, reasonable and appropriate exercise of the police power of the State, or is it an unreasonable, unnecessary and arbitrary interference with the right of the individual to his personal liberty or to enter into those contracts in relation to labor which may seem to him appropriate or necessary for the support of himself and his family?

Ending


The Lochner era is usually considered to have ended with the overturning of Adkins v. Children's Hospital in the 1937 case of West Coast Hotel Co. v. Parrish
West Coast Hotel Co. v. Parrish
West Coast Hotel Co. v. Parrish, , was a decision by the United States Supreme Court upholding the constitutionality of minimum wage legislation enacted by the State of Washington, overturning an earlier decision in Adkins v. Children's Hospital,...

. An often-cited account explaining the ending is that the Supreme Court bowed to political pressure after President Roosevelt's announcement of a legislative proposal to enlarge the Court. The Judicial Procedures Reform Bill of 1937 would have allowed for the President to appoint an additional Justice, up to a maximum of six, for every sitting member over the age of 70½. The official reason for the bill was that the older Justices were unable to handle the increasing workload; but it was widely recognized that the real purpose was to obtain favorable rulings on New Deal
New Deal
The New Deal was a series of economic programs implemented in the United States between 1933 and 1936. They were passed by the U.S. Congress during the first term of President Franklin D. Roosevelt. The programs were Roosevelt's responses to the Great Depression, and focused on what historians call...

 legislation that had previously been ruled unconstitutional. In West Coast Hotel, Justice Owen Roberts, who had previously voted to strike down similar legislation, joined the wing more sympathetic to the New Deal and upheld a Washington state law setting a minimum wage for women. Roberts' move came to be known as "the switch in time that saved nine" as Roosevelt's court-packing plan ultimately failed.

This traditional interpretation of events has been disputed. Barry Cushman, in the book Rethinking the New Deal Court: The Structure of a Constitutional Revolution, argues that the real shift occurred in Nebbia v. New York
Nebbia v. New York
Nebbia v. New York, 291 U.S. 502 , was a case in which the Supreme Court of the United States determined whether the state of New York could regulate the price of milk for dairy farmers, dealers, and retailers....

 (1934), in which the Court by a one-vote majority upheld state legislation regulating the price of milk. In Cushman's view, the laissez-faire constitutionalism that had been the distinctive feature of the Lochner era eroded after World War I
World War I
World War I , which was predominantly called the World War or the Great War from its occurrence until 1939, and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918...

 as high unemployment made the regulation of labor relations an increasingly pressing concern. This development was accompanied by an evolving view of Congress' power under the Commerce Clause
Commerce Clause
The Commerce Clause is an enumerated power listed in the United States Constitution . The clause states that the United States Congress shall have power "To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes." Courts and commentators have tended to...

 to regulate in the public interest. Gradually, the Court came to view the regulation of a previously delimited private sphere as a valid exercise of police power, and the decision in Nebbia signaled the undoing of a doctrinal distinction between public and private enterprise that had been the underlying principle for a free market approach to constitutional interpretation. Cushman contends, then, that the true cause for the demise of the Lochner era was not short-term political considerations by the Court, but an evolving judicial perspective on the validity of governmental regulation.

Alan J. Meese has pointed out that several members of the Court, even after the decision in West Coast Hotel, continued to apply Lochnerian premises. The decision did not overrule Lochner v. New York or any other liberty of occupation case not involving an attempt to require employers to pay a subsistence wage. It was not until Roosevelt began appointing new Justices, starting with Hugo Black
Hugo Black
Hugo Lafayette Black was an American politician and jurist. A member of the Democratic Party, Black represented Alabama in the United States Senate from 1927 to 1937, and served as an Associate Justice of the Supreme Court of the United States from 1937 to 1971. Black was nominated to the Supreme...

United States v. Carolene Products Co.
United States v. Carolene Products Company, 304 U.S. 144 , was an April 25, 1938 decision by the United States Supreme Court. The case dealt with a federal law that prohibited filled milk from being shipped in interstate commerce...

 (1938), the Court held that the constitutional authority of state and federal legislatures over economic matters is plenary, and that laws passed to regulate such matters are entitled to a presumption of constitutionality. Black, in a 1949 opinion upholding a state law prohibiting union discrimination, wrote that the Court by then had repudiated "the Allgeyer-Lochner-Adair-Coppage constitutional doctrine".

Assessment

The Lochner era has been widely criticized for judicial activism

 and is generally perceived as a regrettable period in the history of the Supreme Court. Barbara J. Flagg has identified two broad strains of criticism: the Court's failure to engage in meaningful analysis of existing unequal distributions of wealth and power, and its tendency to substitute its own judgement for that of the legislatures. Criticism among conservative scholars has focused on the use of substantive due process as a vehicle for protecting rights not explicitly mentioned in the Constitution. Robert Bork

 has called the Court's decision in Lochner v. New York an "abomination" that "lives in the law as a symbol, indeed the quintessence of judicial usurpation of power."

The Lochner era has, however, found support among libertarian scholars who defend the Court for securing property rights and economic freedom. Richard A. Epstein has contested the widespread allegation of judicial activism, stating that "[t]he conceptual defense of the Lochner era is much stronger on structural grounds than its manifold critics commonly suppose." Michael J. Phillips, in the book The Lochner Court, Myth and Reality, makes the case that the conventional view of the Lochner era as deeply reactionary is misguided and that the Court's "occasional exercises of economic activism were not entirely, or even mainly, bad things."
