A state statute which requires locomotive engineers and other
persons, employed by a railroad company in a capacity which calls
for the ability to distinguish and discriminate between color
signals to be examined in this respect from time to time by a
tribunal established for the purpose, and which exacts a fee from
the company for the service of examination, does not deprive the
company of its property without due process of law, and, so far as
it affects interstate commerce, is within the competency of the
state to enact until Congress legislates on the subject.
The provision in Article III of the Constitution of the United
States which provides that the trial of all crimes "shall he held
in the state where the said crimes shall have been committed"
relates only to trials in federal Courts, and has no application to
trials in state Courts.
The case is stated in the opinion of the Court.
Page 128 U. S. 97
MR. JUSTICE FIELD delivered the opinion of the Court.
A statute of Alabama which took effect on the first of June,
1887, "for the protection of the traveling public against accidents
caused by color blindness and defective vision" declares that all
persons afflicted with color blindness and loss of visual power to
the extent therein defined are
"disqualified from serving on railroad lines within the state in
the capacity of locomotive engineer, fireman, train conductor,
brakeman, station agent, switchman, flagman, gate tender, or
signalman, or in any other position which requires the use or
discrimination of form or color signals,"
and makes it a misdemeanor, punishable by fine of not less than
ten nor more than fifty dollars for each offense, for a person to
serve in any of the capacities mentioned without having obtained a
certificate of fitness for his position in accordance with the
provisions of the act. It provides for the appointment by the
governor of a suitable number of qualified medical men throughout
the state to carry the law into effect, and for the examination by
them of persons to be employed in any of the capacities mentioned,
prescribes rules to govern the action of the examiners, and allows
them a fee of three dollars for the examination of each person. It
declares that reexaminations shall be made once in every five
years, and whenever sickness or fever or accidents calculated to
affect the visual organs have occurred to the parties, or a
majority of the board may direct; that the examinations and
reexaminations shall be made at the expense of the railroad
companies, and that it shall be a misdemeanor, punishable by a fine
of not less than fifty nor more than five hundred dollars for each
offense, for any such company to employ a person in any of the
capacities mentioned who does not possess a certificate of fitness
therefor from the examiners insofar as color blindness and the
visual organs are concerned. The defendant, the Nashville,
Chattanooga and St. Louis Railway Company, is a corporation created
under the laws of
Page 128 U. S. 98
Tennessee, and runs its trains from Nashville, in that state, to
various points in other states; twenty-four miles of its line being
in Alabama, two miles in Georgia, seven in Kentucky, and four
hundred sixty-four in Tennessee.
On the 2d of August, 1887, one James Moore was employed by the
company as a train conductor on it road, and acted in that capacity
in the County of Jackson, in Alabama, without having obtained a
certificate of his fitness so far as color blindness and visual
powers were concerned, in accordance with the law of that state.
For this employment the company was indicted in the Circuit Court
of the state for Jackson County under the statute mentioned, and on
its plea of not guilty was convicted, and fined fifty dollars. On
appeal to the supreme court of the state, the judgment was
affirmed, and to review it the case is brought in error to this
Court.
It was contended in the court below, among other things, that
the statute of Alabama was repugnant to the power vested in
Congress to regulate commerce among the states, and that it
violated the clause of the Fifth Amendment which declares that no
person shall be deprived of his property without due process of
law. The same positions are urged in this Court, with the further
position that the statute is in conflict with the clause in the
third article of the Constitution which provides that the trials of
all crimes shall be held in the state where they were
committed.
The first question thus presented is covered by the decision of
this Court rendered at the last term in
Smith v. Alabama,
124 U. S. 465. In
that case, the law adjudged to be valid required, as a condition
for a person to act as an engineer of a railroad train in that
state, that he should be examined as to his qualifications by a
board appointed for that purpose, and licensed if satisfied as to
his qualifications, and made it a misdemeanor for anyone to act as
engineer who violated its provisions. The act now under
consideration only requires an examination and license of parties,
to be employed on railroads in certain specific capacities, with
reference to one particular qualification -- that relating to his
visual organs,
Page 128 U. S. 99
but this limitation does not affect the application of the
decision. If the state could lawfully require an examination as to
the general fitness of a person to be employed on a railway, it
could, of course, lawfully require an examination as to his fitness
in some one particular. Color blindness is a defect of a vital
character in railway employees in the various capacities mentioned.
Ready and accurate perception by them of colors and discrimination
between them are essential to safety of the trains, and of course
of the passengers and property they carry. It is generally by
signals of different colors, to each of which a separate and
distinct meaning is attached, that the movement of trains is
directed. Their starting, their stopping, their speed, the
condition of switches, the approach of other trains, and the tracks
in such case which each should take, are governed by them. Defects
of vision in such cases on the part of anyone employed may lead to
fatal results. Color blindness, by which is meant either an
imperfect perception of colors or an inability to recognize them at
all or to distinguish between colors or between some of them, is a
defect much more common than is generally supposed. Medical
treatises of recognized merit on the subject represent, as the
result of extended examinations, that a fraction over four percent
of males are color blind. With some, the defect is congenital, with
others brought on by occupations in which they have been engaged,
or by vicious habits in the use of liquors or food in which they
have indulged. It presents itself in a great variety of forms, from
an imperfect perception of colors to absolute inability to
recognize them at all.
Such being the proportion of males thus affected, it is a matter
of the greatest importance to safe railroad transportation of
persons and property that strict examination be made as to the
existence of this defect in persons seeking employment on railroads
in any of the capacities mentioned.
It is conceded that the power of Congress to regulate interstate
commerce is plenary; that, as incident to it, Congress may
legislate as to the qualifications, duties, and liabilities of
employees and others on railway trains engaged in that commerce,
and that such legislation will supersede any state
Page 128 U. S. 100
action on the subject. But until such legislation is had, it is
clearly within the competency of the states to provide against
accidents on trains while within their limits. Indeed, it is a
principle fully recognized by decisions of state and federal courts
that wherever there is any business in which, either from the
products created or the instrumentalities used, there is danger to
life or property, it is not only within the power of the states,
but it is among their plain duties, to make provision against
accidents likely to follow in such business, so that the dangers
attending it may be guarded against so far as is practicable.
In
Smith v. Alabama, this Court, recognizing previous
decisions where it had been held that it was competent for the
state to provide redress for wrongs done and injuries committed on
its citizens by parties engaged in the business of interstate
commerce, notwithstanding the power of Congress over those
subjects, very pertinently inquired:
"What is there to forbid the state, in the further exercise of
the same jurisdiction, to prescribe the precautions and safeguards
foreseen to be necessary and proper to prevent by anticipation
those wrongs and injuries which, after they have been inflicted, it
is admitted the state has power to redress and punish? If the state
has power to secure to passengers conveyed by common carriers in
their vehicles of transportation a right of action for the recovery
of damages occasioned by the negligence of the carrier in not
providing safe and suitable vehicles, or employees of sufficient
skill and knowledge, or in not properly conducting and managing the
act of transportation, why may not the state also impose on behalf
of the public, as additional means of prevention, penalties for the
nonobservance of these precautions? Why may it not define and
declare what particular things shall be done and observed by such a
carrier in order to insure the safety of the persons and things he
carries, or of the persons and property of others liable to be
affected by them?"
Of course but one answer can be made to these inquiries, for
clearly what the state may punish or afford redress for when done
it may seek by proper precautions in advance to prevent. And the
Court in that case
Page 128 U. S. 101
held that the provisions in the statute of Alabama were not
strictly regulations of interstate commerce, but parts of that body
of the local law which governs the relation between carriers of
passengers and merchandise and the public who employ them, which
are not displaced until they come in conflict with an express
enactment of Congress in the exercise of its power over commerce,
and that until so displaced, they remain as the law governing
carriers in the discharge of their obligations, whether engaged in
purely internal commerce of the state or in commerce among the
states. The same observations may be made with respect to the
provisions of the state law for the examination of parties to be
employed on railways with respect to their powers of vision. Such
legislation is not directed against commerce, and only affects it
incidentally, and therefore cannot be called, within the meaning of
the Constitution, a regulation of commerce. As said in
Sherlock
v. Alling, 93 U. S. 99,
93 U. S. 104,
legislation by a state of that character,
"relating to the rights, duties, and liabilities of citizens,
and only indirectly and remotely affecting the operations of
commerce, is of obligatory force upon citizens within its
territorial jurisdiction, whether on land or water or engaged in
commerce, foreign or interstate, or in any other pursuit."
In our judgment, the statute of Alabama under consideration
falls within this class.
The second position of the plaintiff in error, that the state
statute is repugnant to the provision of Article III of the
Constitution, which declares that the trial of all crimes shall be
held in the state where they have been committed, is readily
disposed of. The provision has reference only to trials in the
federal courts; it has no application to trials in the state
courts.
As to the third position of the plaintiff in error, assuming
that counsel intended to rely upon the fourteenth instead of the
Fifth Amendment (as the latter only applies a limit to federal
authority, not restricting the powers of the state), we do not
think it tenable.
Barron v.
Baltimore, 7 Pet. 243;
Livingston
v. Moore, 7 Pet. 469. Requiring railroad companies
to pay the fees allowed for the examination of parties who
Page 128 U. S. 102
are to serve on their railroads in one of the capacities
mentioned is not depriving them of property without due process of
law. It is merely imposing upon them the expenses necessary to
ascertain whether their employees possess the physical
qualifications required by law.
Judgment affirmed.
