(after stating the facts). No question is made that the application to the board for a franchise did not in all respects comply with the law, and the only question for decision here is whether the law requires the Board of Railroad Incorporation to grant the franchise upon proper application without discretion as to whether it should be done or not.
The act provides, so far as it relates to the question here, as follows:
“Section 1. Any person or any corporation authorized by its charter so to do may erect and maintain on his or its own land a water mill and dam to raise the water to obtain power, or to create a reservoir for storage for equalizing the flow of water for his or its own use, and the uses of the mills below, upon and across any nonnavigable stream, upon the terms and conditions and subject to regulations hereafter expressed.
“Section 2. Any corporation organized under the statutes' of this State for incorporation of companies for manufacturing purposes, for the purpose of producing power for manufacturing or reduction plants, for mining, milling, jigging operations, public utilities or other lawful purposes, or who own a general or practicable principal power or dam site, and who have procured a charter for the developnent and operation of a water power, and who have filed with the Secretary of State and with the counties in which the lands pertaining to such power are situated a plat or survey, showing the location of its principal dam site and the lands necessary for the development of such water power, niay erect auxiliary and storage *52dams across nonnavigable streams for the purpose of developing a water * * * .
“Such power to be for public use and let to parties desiring-it in order of their application. And the State Board of Railroad Commissioners is authorized to grant to such corporations the franchise of erecting such dam or dams, which franchise shall state the maximum compensation per horse power to be received by such corporation for the use of the power generated.”
It will be seen that the act gives to the said board the authority to act in matters of granting the franchise for the erection of dams, and in Garland Power & Development Company v. The Board of Railroad Incorporation, 94 Ark. 423, this court held that the Board of Railroad Incorporation and not the Railroad Commission of the State was intended to be specified in such act and granted a mandamus against the board, requiring it to act upon the application therefor. In passing upon the question, the court said, “In order to arrive at the intent of the Legislature as to which of these boards or commissions it desired to name by this act, it is well to consider the duties imposed upon and the powers given to each by statute at the time of the passage of the act. Nor is it but reasonable to presume that the Legislature in adding this duty to the board or commission then in existence ntended to place it with the board or commission having similar duties to perform. At the time of the passage of the act, the principal duty of the Railroad Commission of Arkansas was to make reasonable and just rates of freight, etc., * * * and it did not have the power * * * to grant any franchise to any corporation. It was, however, at the time of the passage of this act the principal duty of the State Board of Railroad Incorporation to grant charters to railroads and thus to issue franchises. The duty imposed by the act of May 13, 1905, to issue franchises of the character herein applied for was similar to the duties then performed by the State Board of Railroad Incorporation. It is true, that in this act it is also provided that the maximum compensation or rate per horse power, shall be fixed, and the duties of the Railroad Commission of Arkansas relates to the regulation of rates and tariffs. But we are of the opinion that the issuance of the franchise *53was the primary object of this act in designating the board or commission that should perform this duty. * * * The writ of mandamus however, will not be granted to review the exercise of any discretion of any officer or board. It can only be invoked to compel the officer or board to exercise such discretion.” (Citing cases.)
“In this case it is alleged that the board refused to take any action upon the application made to it for the franchise, because the members of the board were of the opinion that they were not the body designated by this act to perform that duty. We are of the opinion that the Legislature had the right to add to the State Board of Railroad Incorporation the duty to issue the franchise and by this act that board is designated to perform that duty and to exercise within its proper discretion that power.”
It has not been questioned that the said board has a discretion in the granting of franchises to railroads, in accordance with the power given by the act establishing it, and the above decision appears to hold also that the board has such discretion in the matter of granting franchises for the development of water power, under the provisions of said Act 323, which will not be controlled by the court, and which was only required to be exercised under the mandamus granted in said cause.
It is true the act says that any corporation, authorized by its charter to do so may erect and maintain on its land a water mill and dam to raise the water to obtain power, etc., and that any company organized under the statutes of this State for the purpose of producing power for manufacturing and reduction plants who own a general or practicable principal power or dam site and who have procured a charter for the operation and development of water power may erect auxiliary storage dams, etc., and, “The State Board of Railroad Commissioners is authorized to grant such corporations the franchise of erecting such dam or dams, which franchise shall state the maximum compensation per horse power to be received by such corporation for the use of the power generated.”
It is insisted for appellant that while this language is permissive, that since it is a public service corporation, in the operation of which the public has an interest, that it must *54be construed to be mandatory and said board required to grant the franchise without discretion.
Sutherland says: “Permissive words in respect to courts or officers are imperative in those cases in which the public or individuals have a right that the power so conferred be exercised. Such words, when used in a statute, will be construed as mandatory for the purpose of sustaining and enforcing rights, but not for the purpose of creating a right or determining its character.” Sutherland Statutory Construction, § 462, p. 597.
Endlich says: “The intent is to be judged of by the purposes of the statute. Where those purposes are to provide for the doing of something for the' sake of justice, something which concerns the public rights or interest, or for the doing of which the public has a claim de jure; something which concerns and subserves third parties and for the doing of which they have a claim based upon existing rights, and of course, where the thing to be done concerns and subserves rights both of the public and of individuals. In all these cases, an intent is to be inferred that in using a permissive phrase, the Legislature meant to enjoin an imperative duty.” Endlich, Interpretation of Statutes, § 312, p. 427.
Sutherland, after discussing the cases, says: “Whether merely permissive, or imperative, depends upon the intention as disclosed by the nature of the act in connection with which the word is employed and the context.”
In note'to the ease of Thompson v. N. Y. & Harlem R. R. Co., 3 Sandford’s Chy, the editor says: “Statutes are never construed as imposing a duty to exercise the power conferred by them, unless the public interest requires it, or a party before the court is entitled, by virtue of an antecedent right, to have the power exercised for his own benefit,” and on page 630, “The true rule of construction applicable to such cases is that the word ‘may’ means ‘must’ or ‘shall’ only in cases where the public interests and rights are concerned, and where the public or third persons have a claim de jure, that the power should be exercised.”
The ordinary meaning of the language must be presumed to be intended unless it would manifestly defeat the object *55of the provision, as said by Justice Story in Minor v. Bank, 1 Peters 46.
In Thompson v. Carroll, 22 How. 422, the court, denying to such words a mandatory significance, said: “It is only where it is necessary to give effect to the clear policy and intention of the Legislature, that such a liberty can be taken with the plain words of the statute.” •
In Gilmore v. City of Utica, 24 N. E. 1009, the New York Court of Appeals said: “The language is held to be mandatory in such cases, not arbitrarily, but because such is supposed to have been the legislative intention. There must be a definite, plain, public interest, or a vested, well-defined private right, and then it will very justly be supposed that the Legislature meant to subserve the public interest, or to give effect to or secure, the private right.”
Our own court, in Whittington, Ex parte, 34 Ark. 394, said: “Permissive words in a statute in many cases impose a duty on tribunals which will be enforced by mandamus, but it is always in cases where the public interests, or vested private rights, are to be thereby protected or enforced etc.” The power to give the citizen full, adequate and complete relief, or the power to promote the public interest in some prescribed mode, implies the duty to exercise it when the occasion arises. In all other cases the word “may” shall imply discretion and is used in contradistinction to “must” or “shall.” The language used, “Is authorized to grant to such corporations, the franchise, etc.,” is permissive and its ordinary meaning is to confer authority to be exercised with discretion, and this meaning is presumed to have been intended unless it would manifestly defeat the object and purpose of the provision. The power to grant the franchise is given to a board authorized to exercise discretion in the granting of other franchises, and if it was to have no discretion in this matter, other terms mandatory and imperative would have been employed, or the Legislature could as well in such event and doubtless would have granted the franchise to all business corporations incorporated under the general laws for that purpose upon filing their articles with the Secretary of State.
No right to operate a public utility has been acquired by appellant corporation, nor has the public any interest in *56the granting of a franchise to it. The public, it is true, has an interest in the development of power from its water courses and the operation of utilities thereby, but its interests can as well be subserved by the exercise of such franchise and the development of such power by one corporation as another, and the Board of Railroad Incorporation having decided that the grant of a franchise for the operation and development of water power at the place designated by appellant might interfere with and prevent the'proper development and operation of such power under the franchise already granted, refused a like grant to appellant.
The purpose of the act will not be defeated by giving the permissive language used its ordinary meaning, which implies a discretion left with the board, to determine when such franchises shall be granted, and it had the right to exercise such discretion. Its discretion can not be controlled by mandamus, which is granted only to protect a clear legal right and to prevent a failure of justice. Fitch v. McDiarmid, 26 Ark. 482; State v. Anderson, 76 N. W. 482; Am. & Eng. Ency. of Law, p. 753-b; 25 Cyc. 155; State v. Fagan, 27 Atl. (N. J.) 1089.
The court did not err in denying the writ and its judgment is affirmed.
