Life, liberty, property and equal protection of the laws, as
grouped together in the Constitution, are so related that the
deprivation of any one may lessen or extinguish the value of the
others.
Insofar as a man is deprived of the right to labor, his liberty
is restricted, his capacity to earn wages and acquire property is
lessened, and he is denied the protection which the law affords
those who are permitted to work.
Liberty means more than freedom from servitude, and the
constitutional guarantee is an assurance that the citizen shall be
protected in the right to use his powers of mind and body in any
lawful calling.
A state may prescribe qualifications and require an examination
to test the fitness of any person to engage, or remain, in the
public calling.
While the state may legislate in regard to the fitness of
persons privately employed in a business in which public health and
safety are concerned, the tests and prohibitions must be enacted
with reference to such business, and not so as to unlawfully
interfere with private business or impose unusual and unnecessary
restrictions upon lawful occupations.

Arbitrary tests by which competent persons are excluded from
lawful employment must be avoided in state regulations of
employment in private business affecting public health and safety.
Smith v. Alabama, 124 U. S. 465.
The statute of Texas of 1909 prohibiting any person from acting
as a conductor on a railroad train without having for two years
prior thereto worked as a brakeman or conductor of a freight train,
and prescribing no other qualifications, excludes the whole body of
the
Page 233 U. S. 631
public from the right to secure employment a conductor, and
amount, as to persons competent to fill the position but who have
not the specified qualification, to a denial of the equal
protection of the law.
A state cannot, in permitting certain competent person to accept
a specified private employment, lay down a test which absolutely
prohibits other competent persons from entering that
employment.
Quaere whether such a statute is not also
unconstitutional under the Commerce Clause as applied to conductor
employed on train engaged in interstate commerce.
The facts, which involve the constitutionality of the statute of
Texas of 1909 prescribing qualifications for conductors on railroad
trains, are stated in the opinion.
Page 233 U. S. 635
MR. JUSTICE LAMAR delivered the opinion of the Court.
W. W. Smith, the plaintiff in error, a man forty-seven years of
age, had spent twenty-one years in the railroad business. He had
never been a brakeman or a conductor, but for six years he served
as fireman, for three years ran as extra engineer on a freight
train, for eight years was engineer on a mixed train, hauling
freight and passengers, and for four years had been engineer on a
passenger train of the Texas & Gulf Railway. On July 22, 1910,
he acted as conductor of a freight train running between two Texas
towns on that road. There is no claim in the brief for the state
that he was not competent to perform the duties of that position.
On the contrary, it affirmatively and without contradiction
appeared that the plaintiff in error, like other locomotive
engineers, was familiar with the duties of that position, and was
competent to discharge them with skill and efficiency. He was,
however, found guilty of the offense of violating the Texas statute
which makes it unlawful for any person to act [
Footnote 1] as conductor of a freight train
without having
Page 233 U. S. 636
previously served for two years as conductor or brakeman on such
trains. On that verdict, he was sentenced to pay a fine, and, the
judgment having been affirmed, the case is here on a record in
which he contends that the statute under which he was convicted
violated the provisions of the Fourteenth Amendment.
1. Life, liberty, property, and the equal protection of the law,
grouped together in the Constitution, are so related that the
deprivation of any one of those separate and independent rights may
lessen or extinguish the value of the other three. Insofar as a man
is deprived of the right to labor, his liberty is restricted, his
capacity to earn wages and acquire property is lessened, and he is
denied the protection which the law affords those who are permitted
to work. Liberty means more than freedom from servitude, and the
constitutional guaranty is an assurance that the citizen shall be
protected in the right to use his powers of mind and body in any
lawful calling.
If the service is public, the state may prescribe qualifications
and require an examination to test the fitness of any person to
engage in or remain in the public calling.
Ex Parte
Lockwood, 154 U. S. 116;
Hawker v. New York, 170 U. S. 189;
Watson v. Maryland, 218 U. S. 173. The
private employer may likewise fix standards and tests, but, if his
business is one in which the public health or safety is concerned,
the state may legislate so as to exclude from work in such private
calling those whose incompetence might cause injury to the public.
But, as the public interest is the basis of such legislation, the
tests and prohibition should be enacted with reference to that
object, and so as not unduly to "interfere with private business,
or impose unusual and unnecessary restrictions upon lawful
occupations."
Lawton v. Steele, 152
U. S. 137.
A discussion of legislation of this nature is found in
Nashville &c. Ry. v. Alabama, 128 U.
S. 98, where this Court sustained the validity of a
statute which required
Page 233 U. S. 637
all locomotive engineers to submit to an examination for color
blindness, and then provided that those unable to distinguish
signals should not act as engineers on railroad trains. That
statute did not prevent any competent person from being employed,
but operated merely to exclude those who, on examination, were
found to be physically unfit for the discharge of a duty where
defective eyesight was almost certain to cause loss of life or
limb. Another case cited by the plaintiff in error is that of
Dent v. West Virginia, 129 U. S. 114. The
act there under review provided that no one except licensed
physicians should be allowed to practice medicine, and declared
that licenses should be issued by the state board of health only to
those (1) who were graduates of a reputable medical college, (2) to
those who had practiced medicine continuously for ten years, or (3)
to those who, after examination, were found qualified to practice.
Ten years' experience was accepted as proof of fitness, but such
experience was not made the sole test, since the privilege of
practicing was attainable by all others who, by producing a diploma
or by standing an examination, could show that they were qualified
for the performance of the duties of the profession. In answer to
the contention that the act was void because it deprived the
citizen of the liberty to contract and the right to labor, the
court said no objection could be raised to the statutory
requirements
"because of their stringency or difficulty. It is only when they
have no relation to such calling or profession, or are unattainable
by such reasonable study and application, that they can operate to
deprive one of his right to pursue a lawful vocation."
The necessity of avoiding the fixing of arbitrary tests by which
competent persons would be excluded from lawful employment is also
recognized in
Smith v. Alabama, 124 U.
S. 465,
124 U. S. 480.
There, the act provided that all engineers should secure a license,
and in sustaining the
Page 233 U. S. 638
validity of the statute, the court pointed out that the law
"requires that every locomotive engineer shall have a license,
but it does not limit the number of persons who may be licensed, or
prescribe any arbitrary conditions of the grant."
This and the other cases establish beyond controversy that, in
the exercise of the police power, the state may prescribe tests and
require a license from those who wish to engage in or remain in a
private calling affecting the public safety. The liberty of
contract is, of course, not unlimited, but there is no reason or
authority for the proposition that conditions may be imposed by
statute which will admit some who are competent and arbitrarily
exclude others who are equally competent to labor on terms mutually
satisfactory to employer and employee. None of the cases sustains
the proposition that, under the power to secure the public safety,
a privileged class can be created and be then given a monopoly of
the right to work in a special or favored position. Such a statute
would shut the door, without a hearing, upon many persons and
classes of persons who were competent to serve, and would deprive
them of the liberty to work in a calling they were qualified to
fill with safety to the public and benefit to themselves.
2. The statute here under consideration permits those who had
been freight conductors for two years before the law was passed,
and those who for two years have been freight conductors in other
states, to act in the same capacity in the State of Texas. But,
barring these exceptional cases, the act permits brakemen of
freight trains to be promoted to the position of conductor on a
freight train, but excludes all other citizens of the United States
from the right to engage in such service. The statute does not
require the brakeman to prove his fitness, though it does prevent
all others from showing that they are competent. The act prescribes
no other qualification for appointment as conductor than that for
two years the
Page 233 U. S. 639
applicant should have been a brakeman on a freight train, but
affords no opportunity to any others to prove their fitness. It
thus absolutely excludes the whole body of the public, including
many railroad men, from the right to secure employment as conductor
on a freight train.
For it is to be noted that, under this statute, not only the
general public, but also four classes of railroad men, familiar
with the movement and operation of trains and having the same kind
of experience as a brakeman, are given no chance to show their
competency, but are arbitrarily denied the right to act as
conductors. The statute excludes firemen and engineers of all
trains, and all brakemen and conductors of passenger trains. But no
reason is suggested why a brakeman on a passenger train should be
denied the right to serve in a position that the brakeman on a
freight train is permitted to fill. Both have the same class of
work to do, both acquire the same familiarity with rules, signals,
and methods of moving and distributing cars, and if the training of
one qualifies him to serve as conductor, the like training of the
other should not exclude him from the right to earn his living in
the same occupation.
It is argued in the brief for the state that, in practice,
brakemen on freight trains are generally promoted to the position
of freight conductors, and then to the position of conductors on
passenger trains. And yet, under this act, even passenger
conductors of the greatest experience and highest capacity would be
punished if they acted as freight conductors without having
previously been brakemen.
The statute not only prevents experienced and competent men in
the passenger service from acting as freight conductors, but it
excludes the engineer on a freight train -- even though, under the
rules of all railroads, the freight engineer now acts as conductor
in the event the regular conductor is disable en route. This
general custom
Page 233 U. S. 640
is a practical recognition of their qualification, and is
founded on the fact that the engineer, by virtue of his position,
is familiar with the rules and signals relating to the train's
movement, and peculiarly qualified for the performance of the
duties of conductor. If we cannot take judicial knowledge of these
facts, the record contains affirmative proof on the subject. For,
according to the testimony [
Footnote 2] of the state's witness,
"acting as engineer on
Page 233 U. S. 641
a freight train would better acquaint one with the knowledge of
how to operate a freight train than acting as brakeman."
And yet, though at least equally competent, the engineer is
denied the right to serve as conductor, and the exclusive right of
appointment and promotion to that position is conferred upon
brakemen.
3. So that the case distinctly raises the question as to whether
a statute, in permitting certain competent men to serve, can lay
down a test which absolutely prohibits other competent men from
entering the same private employment. It would seem that to ask the
question is to answer -- and the answer in no way denies the right
of the state to require examinations to test the fitness and
capacity of brakemen, firemen, engineers, and conductors to enter
upon a service fraught with so much of risk to themselves and to
the public. But all men are entitled to the equal protection of the
law in their right to work for the support of themselves and
families. A statute which permits the brakeman to act -- because he
is presumptively competent -- and prohibits the employment of
engineers and all others who can affirmatively prove that they are
likewise competent is not confined to securing the public safety,
but denies to many the liberty of contract granted to brakemen, and
operates to establish rules of promotion in a private
employment.
If brakemen only are allowed the right of appointment to the
position of conductors, then a privilege is given to them which is
denied all other citizens of the United States. If the statute can
fix the class from which conductors on freight trains shall be
taken, another statute could limit the class from which brakeman
and conductors on passenger trains could be selected, and so,
progressively, the whole matter as to who could enter the railroad
service, and who could go from one position to another, would be
regulated by statute. In the nature of the case, promotion is a
matter of private business management, and
Page 233 U. S. 642
should be left to the carrier company, which, bound to serve the
public, is held to the exercise of diligence in selecting competent
men, and responsible in law for the acts of those who fill any of
these positions.
4. There was evidence that Smith safely and properly operated
the train which had in it cars containing freight destined for
points in Texas, Missouri, Oklahoma, and Kansas. But, in view of
what has been said, it is not necessary to consider whether the
plaintiff, as engineer, was in a position to raise the point that,
under the decision in
Adams Express Co. v. City of New
York, 232 U. S. 14, the
statute interfered with interstate commerce.
The judgment is reversed, and the case remanded to the Court
of Criminal Appeals of the Texas for further proceedings not
inconsistent with this opinion.
MR. JUSTICE HOLMES dissents.

Act of March 11, 1909, c. 46, General Laws of Texas 1909, p.
92.
[
Footnote 2]
"I understand the railroad business, and know that a locomotive
engineer learns as much about how a freight train should be
operated by a conductor as a brakeman or conductor. Acting as
engineer on a freight train will better acquaint one with a
knowledge of how to operate a freight train than acting as
brakeman. Under the rules of all railroads, and of the Texas &
Gulf Railway Company, the engineer is held equally responsible with
the conductor for the safe operation of the train. All orders are
given to the engineer as well as to the conductor. Every order sent
to a conductor in a train is made in duplicate, and one copy of it
is given to the conductor and the other to the engineer. It is a
rule with railway companies that, if anything should happen to
disable the conductor, or in any way prevent his proceeding with
his train, the engineer is to immediately take charge of the train
and handle it into the terminal. The engineer is constantly with
the train, and knows all of the signals, knows how the couplings
are made, knows how the cars are switched and distributed, and
knows how they are taken into the train and transported from one
place to another. An engineer is so constantly associated with all
the work of a conductor on a freight train that he should know as
much about how a freight train should be operated by a conductor as
the conductor himself. All actions of the conductor that pertain to
the safe operation of the train are being carried on in his
presence and within his observation all the time. The matter of
handling the waybills and ascertaining the destinations of the cars
in his train is easy and plain, and it does not take a person that
has had experience as a conductor to understand that part of his
service. The waybills are plainly written and the destinations
plainly given, and booking the waybills and delivering them with
the cars is clerical, and can be done by anyone that can read and
write and who has ordinary sense. Every act that is to be done by
the engineer and all of the conductor's acts with reference to this
are in the view and observation of the engineer."
