delivered the opinion of the court.
This is a suit to enjoin the enforcement of a city ordinance of the. City of Portland, pending the submission thereof to a vote of the people by the referendum. On February 26, 1908, an ordinance was enacted by the *94common council of the City of Portland, numbered 17,414, which exacts a license fee for the operation of vehicles, conveyances, and delivery wagons used in the conduct of certain businesses. Within 30 days after the passage of the ordinance a petition invoking a referendum thereon was filed with the auditor of the city; and it is alleged that the city officers are proceeding to enforce the ordinance against the owners of all such vehicles before the same has been approved by the voters of the city. A demurrer to this complaint was sustained by the court, and a decree entered thereon dismissing the suit; and the plaintiff appeals.
1. These issues involve the effect of the legislative act of February 25, 1907, which provides for carrying into, effect the initiative and referendum powers reserved to the people by Section 1 and Section la of Article IV, of the Constitution of Oregon. This necessitates the consideration of several sections of the constitution and of section 49 of the charter of the City of Portland. Section 2 of Article XI of the constitution was amended on June 4, 1906, and now provides:
“Corporations may be formed under general laws, but shall not be created by the legislative assembly by special laws. The legislative assembly shall not enact, amend, or repeal any charter or act of incorporation for any municipality, city, or town. The legal voters of every city and town are hereby granted power to enact and amend their municipal charter, subject to the constitution and criminal laws of the State of Oregon.”
Section 1 of Article IV of the constitution, was amended June 2, 1902, being the initiative and referendum amendment, and is a general reservation by the people of the power to propose laws and amendments to the constitution and to enact or reject the same at the polls, and also the power to approve or reject at the polls any act of the legislative assembly. At the general election of 1906, Article IV of the constitution was again *95amended by adding thereto section la. So far as involved here, it reads in section la:
“* * The initiative and referendum powers reserved to the people by this constitution are hereby further reserved to the legal voters of every municipality and district, as to all local, special, and municipal legislation, of every character, in or for their respective municipalities and districts. The manner of exercising said powers shall be prescribed by general laws, except that cities and towns may provide for the manner of exercising the initiative and referendum powers as to their municipal legislation.”
Section 49 of the charter of the City of Portland (Sp. Laws 1903, p. 20), provides:
“Upon the passage of * * any ordinance, an enrolled copy thereof, attested by the auditor, shall be submitted to the mayor by the auditor, within five days from the passage of the same by the council, and if the mayor approves the same, he shall write upon it ‘Approved,’ with the date thereof, sign it with the name of his office, and thereupon, unless otherwise provided therein, such ordinance shall become a law, and be of force and effect. * *”
The act of the legislative assembly of February 25, 1907 (Laws 1907, p. 398), above referred to, provides for the exercise of the initiative and referendum of the constitution and applies to general, local, special, and municipal legislation. Section 10 of the act provides how the initiative and referendum shall be invoked in cities and towns as to the preparation and filing of the petitions and other preliminary proceedings. Section 11 provides, among other things, that the referendum petition against any ordinance shall be filed with the auditor within 30 days after the passage of such ordinance ; that no city ordinance shall take effect and become operative until 30 days after its passage, except measures necessary for the preservation of the peace, health, and safety of the city.
The contention of the defendants is that as section 49 of the charter provides that an ordinance shall take *96effect immediately upon its approval by the mayor, and Section 2, Article XI, of the constitution, provides that the legislature shall not amend any charter, therefore the act of the legislative assembly of February 25, 1907, in so far as it provides that no ordinance shall take effect until 30 days after its passage, is void, for the reason that it thereby attempts to amend section 49 of the charter. This is the only question involved. Section la, Article IV, of the constitution, is not self-executing, for the reason that it makes no provision as to its enforcement. It only declares or reserves the right, without laying down rules, by means of which this right may be given the force of law. Cooley’s Con. Lim. (7 ed.), 121; Reeves v. Anderson, 13 Wash. 17 (42 Pac. 625). It contains no provisions as to the time and place of filing the petition, nor the time when, or manner in’ which, the law voted upon shall take effect; and, in view of section 49 of the charter, some provision is required to give time and opportunity to invoke the referendum against an ordinance passed by the council; and many other details may be greatly aided by legislation.
2. This was recognized by the framers of this amendment, as it provides therein that the manner of exercising such powe'r shall be prescribed by general laws or by the city. This right of the referendum is reserved to the people of a city or town, regardless of any provisions of the city charter. It is superior to the charter. Cooley’s Con. Lim., § 122, in speaking of a self-executing homestead provision of the constitution and of legislation in aid of it, says:
“It will override and nullify whatever legislation, either prior or subsequent, would defeat or limit the homestead which is defined and secured.”
And so this constitutional provision will override and nullify whatever the charter contains that would defeat or limit the right of the referendum upon ordinances subject thereto. So far as section- la affects or applies *97to a city charter, its provisions may be considered as read into the charter. It amounts to an amendment of it, subject only to such provision of law as shall make it available, and is sufficient authority for any state or city legislation necessary to give it effect, regardless of other provisions contained in the charter.
3. The case of Reeves v. Anderson, 13 Wash. 17 (42 Pac. 625), though not involving this exact question, is very much in point. By the Constitution of Washington, Section 10, Article XI, it is provided that the inhabitants of a city containing a population of 20,000 may frame a charter for their own government, and that the city council may cause an election to be had for the purpose of choosing 15 freeholders to prepare and propose a charter. It further provides that a charter adopted under this article may be amended by proposal of the city council. The State legislature enacted a statute providing the manner of exercising the right conferred by Section 10, Article XI, of the constitution. The city council of Seattle ignored a petition presented thereafter, asking that an election be called to elect 15 freeholders to prepare a new charter by altering, changing, or revising the existing one; and this suit was brought to compel it to call the election. It was contended by defendant that the legislative act is unconstitutional, and that Section 10, Article XI, of the constitution, points out the only manner by which the charter may be amended, namely, upon a proposal from the council, and that the right to “frame a charter” has been once exercised, and thereby exhausted. The. court holds that Section 10, Article XI, of the Constitution, is not self-executing, and that the legislative act is for the purpose of providing the manner of its exercise;-that the power is to “frame a charter; that the right is a continuing right; and that by the act in question the legislature has made it possible for the people to exercise such constitutional right to create a new charter. This being so, it should not be *98held invalid even if' we should conclude that its provisions. concerning amendments are not in accord with the constitution. It would still be valid in so far as it pointed out the manner in which a new charter could-be created.” Although not compulsory upon the voters to adopt it, “this act affords them an opportunity for so doing,, without regard to the will of the council, and in making such provision we think the legislature did not transcend its constitutional functions.” “The act, as we have seen, is in harmony with the spirit of the constitution, and its object is -to further the exercise of a constitutional right and make such right available.” Where the constitution itself calls for the enactment, it cannot be considered unconstitutional because it may conflict with some other constitutional provision. It is held in Ewing v. Hoblitzell, 85 Mo. 64, that an act regulating the registration of voters in certain cities was valid, as it was plainly called for by Section 5, Article VIII, of the constitution, although it overrides the charter which the constitution provided should be amended by the people, “and not otherwise.” And in Kenefick v. City of St. Louis, 127 Mo. 1 (29 S. W. 838), a local or special law is inhibited by the constitution upon the subject considered. It is held that legislation affecting only the city of St. Louis, which is necessary or appropriate to carry into effect-a positive command of the organic law, or is required or directly contemplated by its terms, cannot justly be held either special or local within the true intent and meaning of the constitution.
4. The constitutional provision in this case, standing alone, does not affect section 49 of the charter so as to prevent ordinances from taking effect, as provided therein, but it subordinates that section and the whole charter to such legislative provision as is therein authorized for the effectual exercise of the referendum. Some provision is necessary to suspend the operation of section 49 upon such ordinances as may be subject to the *99referendum and to provide a time within which the referendum may be invoked. This is done by the legislative act of February 25, 1907, which only suspended the operation of section 49 for 30 days upon all ordinances liable to be referred. Section 10 of the legislative act provides, in effect, that the terms of section 9 thereof shall be applied to cities. This relates to the canvass of the vote and subsequent proceedings, including the proclamation by the Governor, declaring the measure to be in full force and effect as the law; but section 10 provides that the city auditor and mayor shall perform these duties that are there required of the Secretary of State and Governor in state legislation. The result is that an ordinance upon which the referendum is invoked will take effect, as provided in section 9 and section 10 of the act of 1907, upon the proclamation of the mayor to that effect. Those subject to the referendum but upon which it is not invoked will take effect by the provisions of section 49 of the charter at the expiration of the 30-day suspension. This legislative act is in pursuance of the specific direction of, and intended by, the constitution to make it possible for the people to exercise the referendum; and we are of the opinion that it is not an amendment by the legislature of section 49 of the city charter within the meaning of Section 2, of Article XI, of the Constitution of Oregon.
Therefore the lower court erred in sustaining the demurrer to the complaint; and the decree will be reversed, and the cause remanded. Reversed.
