Under the equal protection clause, a state may do what it can to
prevent what is deemed an evil and stop short of those cases in
which the harm to the few concerned is thought less important than
the harm to the public that would ensue if the rule were made
mathematically exact. P.
249 U. S.
268.
A law of Arizona (Penal Code, par. 717) placing restrictions
upon the hours of labor of women in hotels, with penalties upon
hotelkeepers for infractions, excepts in part railroad restaurants
or eatinghouses upon railroad rights of way and operated by or
under contract with any railroad company.
Held that the
Court cannot say, upon its judicial knowledge, that the legislature
had no adequate ground for the distinction; possibly one might be
found in the need of adjusting the service in the excepted
restaurants to the hours of trains.
Id.
18 Ariz. 345 affirmed.
The case is stated in the opinion.

MR. JUSTICE HOLMES delivered the opinion of the Court.
This is an information alleging that the defendant, the
plaintiff in error, was engaged in the hotel business and permitted
a woman to work in the hotel for eight hours, and that the "said
eight hours of work was not then and there performed within a
period of twelve hours," with a denial that the defendant was
within the exceptions made by the statute governing the case. The
statute provides as follows:
"Provided further, that the said eight hour period of work shall
be performed within a period of twelve hours, the period of twelve
hours during which such labor must be performed not to be
applicable to railroad restaurants or eatinghouses located upon
railroad rights of way and operated by or under contract
Page 249 U. S. 268
with any railroad company."
Penal Code of Arizona § 717. The defendant, by demurrer and
otherwise, set up that the exceptions in the statute made it void
under the Fourteenth Amendment of the Constitution of the United
States as depriving the defendant of the equal protection of the
laws. There was a trial and judgment against the defendant which
was sustained by the supreme court of the state, Arizona.
The Fourteenth Amendment is not a pedagogical requirement of the
impracticable. The equal protection of the laws does not mean that
all occupations that are called by the same name must be treated in
the same way. The power of the state "may be determined by degrees
of evil or exercised in cases where detriment is specially
experienced."

It may do what it can to prevent what is deemed an evil and stop
short of those cases in which the harm to the few concerned is
thought less important than the harm to the public that would ensue
if the rule laid down were made mathematically exact. The only
question is whether we can say, on our judicial knowledge, that the
Legislature of Arizona could not have had any reasonable ground for
believing that there were such public considerations for the
distinction made by the present law. The deference due to the
judgment of the legislature on the matter has been emphasized again
and again.

S. 297,

Of course, this is especially true when local conditions may affect
the answer, conditions that the legislature does but that we cannot
know.

S. 526,

530-531.
Presumably, or at least possibly, the main custom of restaurants
upon railroad rights of way comes from the passengers upon trains
that stop to allow them to eat. The work must be adjusted to the
hours of the trains. This fact makes a practical and it may be an
important
Page 249 U. S. 269
distinction between such restaurants and others. If, in its
theory, the distinction is justifiable, as for all that we know it
is, the fact that some cases, including the plaintiff's, are very
near to the line makes it none the worse. That is the inevitable
result of drawing a line where the distinctions are distinctions of
degree, and the constant business of the law is to draw such
lines.
"Upholding the Act as embodying a principle generally fair and
doing as nearly equal justice as can be expected seems to import
that, if a particular case of hardship arises under it in its
natural and ordinary application, that hardship must be borne as
one of the imperfections of human things."
Louisville & Nashville R. Co. v. Barber Asphalt
Co., 197 U. S. 430,

We cannot pronounce the statute void.
Judgment affirmed.
