delivered the opinion of the court.
This is an original application in this court for a writ of habeas corpus. On October 31, 1913, O. P. Hoff, Labor Commissioner of Oregon, filed two criminal complaints in the justice’s court for Salem district, Marion County, Oregon, charging R. E. Lee Steiner, superintendent of the Oregon State Hospital, with the violation of the provisions of Chapter 61 of the General Laws of Oregon, for 1913. In one of the complaints the superintendent is charged with having employed and required one W. L. Davis to perform *220labor on October 29, 1913, as a farm hand at the asylum farm, for more than eight hours. In the other complaint, the accused is alleged to have employed and required one Morton Mortesen to perform labor as an engineer at the same time and place, for a period of time in excess of eight hours. Seasonably following the arrest of Mr. Steiner, he applied to this court for a writ of habeas corpus, assigning as reasons therefor that: “There is no law within the state making the acts complained of illegal, and that Chapter 61, of the Laws for 1913, does not apply to laborers employed by the state,” and for that account the justice of the peace had no jurisdiction to issue the warrants of arrest.
The material provisions of the statute, including the title of the act, under which the petitioner is prosecuted, reads:
“An act * * defining the duties of state officials in awarding and carrying out contracts; declaring eight hours to be a day’s labor in all cases where the state or any county, school district, municipality or division is concerned, and prescribing a penalty for violation of the law.
“Section 1. Every contract made with the state, county, school district, municipality, municipal corporation or subdivision shall contain a condition that * * no person shall be employed for more than eight hours in any one day, or forty-eight hours in any one week, unless in case of emergency when no other competent labor is available, and in such eases such laborer shall be paid double wages for all overtime.” “Sec. 4. In all cases where labor is employed by the state, county, school district, municipality, municipal corporation, or subdivision, either directly or through another, as a contractor, no person shall be required or permitted to labor more than eight hours in any one day, or forty-eight hours in any one week, except in cases of necessity, emergency, or where pub-*221lie policy absolutely requires it, in which event the person or persons so employed for excessive hours shall receive double pay for the overtime so employed; and no emergency, necessity, or public policy shall be presumed to exist when other labor or like skill and efficiency which has not been employed full time is available.
“Sec. 5. Eight hours shall constitute a day’s labor in all cases where the state, county, school district, or any municipality, municipal corporation or subdivision is the employer of the labor, either directly or indirectly, by contract with another.
, “Sec. 6. All contractors, subcontractors, or agents, or persons whatsoever in authority or in charge, who shall violate the provisions of this act as to the hours of employment of labor as herein provided, shall be deemed guilty of a misdemeanor and upon conviction shall be fined in a sum of not less than fifty dollars nor more than one thousand dollars, or with imprisonment in the county jail for a period of not less than five days nor more than one year, or by both such fine and imprisonment, in the discretion of the court.”
1. The first and by far the most serious question presented by counsel for. petitioner involves the constitutionality of the statute which attempts to limit the hours of laborers, employed by the state or its auxiliaries, either directly or through the agency of a contractor. The validity of the statute is challenged upon the ground of an alleged violation of the fourteenth amendment of the Constitution of the United States, which inhibits a state from enacting any law which will abridge the privileges and immunities of citizens of the United States, deprive any person of life, liberty, or property without due process of law, or deny to any person within its jurisdiction the equal protection of the law. Also, the statute is assailed as being in contravention of Article I, Section 20, of the state Constitution which provides: “No law shall be *222passed granting to any citizen or class of citizens, privileges * * which, upon the same terms, shall not equally belong to all citizens.”
An examination of the several provisions of the statute, and of the record on appeal, discloses that no question can here arise concerning the power of the legislature to pass a law limiting the hours of labor in purely private work in which the public has no concern. That question we have now no occasion to consider. Confessedly, the legislative enactment has application only to a laborer employed directly or indirectly by the state, or by one of its political agencies. The Constitution of our state does not reveal any express or implied restriction upon the power of the law-making body to determine the maximum number of hours an employee may either be required or permitted to labor for the state, or its agencies of government.
The state has undoubted power to prescribe for itself such rules of conduct as it’deems best suited for the particular work in which it is engaged. It may dictate rules for its own guidance which would be intolerable if applied to private persons in the prosecution of their own activities. But that situation cannot enter into a legal estimate of the statute, or be considered in applying the rules by which its constitutional measure must be taken, as matters of that nature only provoke considerations of public policy with which the courts have no concern. By the legislative act in question the state simply declares that no person shall be permitted or required to perform labor for it, or for any of its administrative agencies, more than eight hours in a calendar day, and that none need apply who desire longer hours of employment. To the contractor of state work, it says no one can work for you in excess of eight hours in a day. No barrier is placed about a laborer preventing him from seeking employ*223ment elsewhere. His liberty of selection is not interfered with, nor his right to labor frustrated. Any individual may, with propriety, declare a policy not to employ within the line of his undertaking any person for a longer period of time than eight hours in a day, or any other unit of time that might appeal to his altruism, and direct his agent to observe that regulation. And by parity of reason, the state, speaking through the legislature, may, with equal fitness, inaugurate a rule of conduct not to work its employees more than eight hours a day, and legally direct its instrumentalities of government faithfully to observe such mandate. The terms of the employment are by this statute publicly proclaimed, and if a person insists upon working more than the hours limited by the act, he must seek elsewhere the engagement of his labor.
In the case of United States v. Martin, 94 U. S. 400 (24 L. Ed. 128), in passing upon an act of Congress declaring that eight hours shall constitute a day’s work, for laborers, workmen, or mechanics employed by or on behalf of the government, the court said:
“We regard the statute chiefly as in the nature of a direction from a principal to his agent that eight hours is deemed to be a proper length of time for a day’s labor, and that his contracts shall be based upon that theory. It is a matter between the principal and his agent, in which a third party has no interest. ’ ’
A careful dissection of this statute warrants the conclusion that the act does not transgress upon any rights vouchsafed, either by the federal or state Constitution, and that the objections which are urged against the law involve matters of political expediency with which the law-making bodies of the state alone are concerned, and to which institutions only may an appeal for correction be made. Indeed, we think the law applicable to this case was settled by the Supreme Court of the United States in the excellently consid*224ered case of Atkin v. Kansas, 191 U. S. 207 (24 Sup. Ct. Rep. 124, 48 L. Ed. 148), wherein Mr. Justice Harlan, speaking for the court, in part said:
“We can imagine no possible ground to dispute the power of the state to declare that no one undertaking work for it, or for one of its municipal agencies, should permit or require an employee on such work to labor in excess of eight hours each day, and to inflict punishment upon those who are embraced by such regulations, and yet disregard’ them. It cannot be deemed a part of the liberty of any contractor that he be allowed to do public work in any mode he may choose to adopt, without regard to the wishes of the state. On the contrary, it belongs to the state, as the guardian and trustee for its people, and having control of its affairs, to prescribe the conditions upon which it will permit public work to be done on its behalf, or on behalf of its municipalities. No court has authority to review its action in that respect. Regulations on this subject suggest only considerations of public policy. And with such considerations the courts have no concern. If it be contended to be the right of everyone to dispose of his labor upon such terms as he deems best— as undoubtedly it is — and that to make it a criminal offense for a contractor for public work to permit or require his employee to perform labor upon that work in excess of eight hours each day is in derogation of the liberty both of employees and employer, it is sufficient to answer that no employee is entitled, of absolute right and as part of his liberty, to perform labor for the state; and no contractor for public work can excuse a violation of his agreement with the state by doing that which the statute under which he proceeds distinctly and lawfully forbids him to do.”
A case of striking analogy to the one in mind is In re Dalton, 61 Kan. 257 (59 Pac. 336, 47 L. R. A. 380). We are not unmindful of an impressive number of cases, the leading one of which is Lochner v. New York, 198 U. S. 45 (49 L. Ed. 937, 25 Sup. Ct. Rep. *225539, 3 Ann. Cas. 1133), that hold those legislative acts unconstitutional which attempt to regulate the right of free contract upon the part of the individual, either as employer or employee. But in our view of the law, that situation does not here present itself. We conclude on this phase of the case that Chapter 61, General Laws of Oregon for 1913, is a mere declaration of policy on the part of the state and its political subdivisions, and does not conflict either with the Constitution of the United States or of this state.
2. The other proposition suggested by counsel for petitioner is whether the engineer of the heating plant at the State Hospital is a laborer within the meaning of the enactment. The statute plainly employs the term “labor” in its widest sense, as reference to Section 4 of the act will denote: “In all cases where labor employed by the state, county, school district, municipality, municipal corporation or subdivision * * no person shall be required or permitted to labor more than eight hours. * * ” Section 5 reads: “Eight hours shall constitute a day’s labor in all cases where the state, etc., is the employer of the labor.” Had the legislature intended to use the word “labor” in a restricted sense, or with reference to a special class of endeavor, a qualifying word or phrase would have been used in connection with the term. The language of the statute is comprehensive, and includes all persons who perform labor for the state or its auxiliaries, whether that labor is skilled or unskilled, so long as the character of the work comes within the definition of the term “labor.” Labor is defined in-Bouvier’s Law Dictionary, volume 2, page 95 (Rawle’s Bev.) as, “work requiring execution or effort, either physical or mental; toil. ’ ’
In the case of Stryker v. Cassidy, 76 N. Y. 50 (32 Am. Rep. 262), the question arose whether an archi*226tect employed by tbe owner to superintend the erection of a house was entitled to lien for his services. As an act of the legislature authorized a lien to be created in favor of “any person who shall perform any labor * * by virtue of a contract with the owner, ’ ’ the court held that the services of the architect were encompassed within the word “labor,” and held the lien to be valid: Knight v. Norris et al., 13 Minn. 473 (Gil. 438); Sleeper v. Goodwin, 67 Wis. 577 (31 N. W. 335).
Considered in the glow of these precedents, we find no other alternative than to declare that the duties of the engineer came within the embrace of the word “labor” as used in the statute.
3. As a final reflection, it will be observed that the statute designates in Section 6 those individuals who may be punished for an infraction of the law as “all contractors, subcontractors, or agents, or persons whatsoever in authority, or in charge. ’ ’ The language employed is sufficiently general to embrace within its fold all persons in charge of a public undertaking, whether acting in the capacity of a contractor, subcontractor or agent, or in the position of one having authority over or in charge' of the work.
Indubitably the language of the act, as well as its aim and purpose, is to place the responsibility of a faithful observance of the law upon those individuals who have charge of the labor in a given public work, thereby reducing to a minimum the wrong which the legislature deemed the statute would correct. By the record, it is admitted that petitioner is the superintendent of the Oregon State Hospital, and as such employs laborers on behalf of and as agent .of the state, and was acting in that capacity at the time of the transgressions laid in the criminal complaints. Truly the petitioner comes within the statute, and is responsible for a violation thereof.
*227The writ will be denied and the petitioner remanded to the custody of the law. Writ Denied.
