BUTTLER, P. J.

Petitioners seek judicial review of four orders of the Portland Metropolitan Area Local Government Boundary Commission approving proposed annexations to the City of Portland of approximately 450 acres of contiguous land east of the present city boundary. The annexations were initiated by the city under ORS 199.490(2), the so-called "triple majority" rule, pursuant to which the city received the written consent to annex their land in writing from more than half of the land owners in the territory proposed to be annexed, who also owned more than half of the land in the territory representing more than half of the assessed value of all real property in the territory. Following public hearings, the city council adopted resolutions approving the annexations, and the boundary commission also approved them. Those orders are subject to judicial review under ORS 183.482. ORS 199.461(4).

The Mid-County Future Alternatives Committee and two residents of the territory are opposed to the annexations and ask that we vacate the boundary commission's decisions, contending that the "triple majority" annexation procedure authorized by ORS 199.490(2) violates the Privileges and Immunities Clause of the Oregon Constitution, Article I, section 20, and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. In the alternative, they contend that the consent process as conducted did not comply with ORS 199.490(2). Because resolution of the case would not be complete without resolving the state constitutional ground, and because we reverse on that ground, we do not reach petitioners' alternate contentions.

The boundary commission is responsible ultimately for approving or disapproving city annexations; its decision to approve the type of "minor boundary change" involved here, however, is subject to approval of the electors in all but one circumstance. First, when a city council initiates an annexation by resolution pursuant to ORS 199.490(1)(a), if there are the requisite number of written objections, a boundary commission order approving the annexation is subject to the approval of the electors in the territory. ORS 199.505(1) and (2). Second, if a city receives the consent of the "triple majority" of the landowners in the territory, it may pass a resolution to annex, and an order of the boundary commission approving annexation is final and not subject to an election, regardless of whether objections are filed. ORS 199.495. Rivergate Residents Assn. v. Portland Metro Area, 70 Or. App. 205, 208-211, 689 P.2d 326 (1984), rev den 298 Or. 553 (1985).

In addition, the annexation process may be initiated by a petition to the boundary commission signed by 10 percent of the electors registered in the affected territory, by a petition of the owners of at least one-half of the land area in the affected territory or by resolution of the boundary commission itself. Under each of those procedures, the electors of the affected territory are entitled to vote if the boundary commission approves the annexation, if the requisite number of objections are filed. ORS 199.505. If there is a health hazard or if the territory to be annexed is surrounded by a city, different procedures may be invoked that require neither the consent of landowners nor an election. See ORS 222.880; ORS 222.750. Those procedures, involving special circumstances that are not classified as "minor boundary changes," are not relevant here.

When the boundary commission receives a resolution or petition for annexation, it is required to cause a study of the proposal to be made and to conduct one or more public hearings before approving, modifying or disapproving the proposal. ORS 199.461; ORS 199.463. Any interested person may seek judicial review of the commission's order. ORS 199.461(4).

The premise of petitioners' state constitutional claim is that the "triple majority" annexation procedure treats landowners who need not and may not be resident electors differently from nonlandowners who are resident electors, in that it permits landowners to give or withhold their consent to an annexation but grants no similar privilege to residents who are not landowners.

In reviewing the claim under the Oregon Constitution, the first inquiry is whether a landowner's ability to give or withhold consent for the annexation of his own land is a substantial enough advantage to be considered a "privilege." The city contends that the consent process confers no privilege on landowners, because it has no binding effect. It is true, as amicus points out, that the filing of the consents does not require the city to proceed under ORS 199.490(2). It may bypass the consent and proceed with annexation under ORS 199.490(1), or it may choose not to proceed with annexation at all. However, it is only the consent of the "triple majority" of the landowners that enables the city to proceed with annexation without an election. Without the "triple majority," there must be an election if the requisite number of written objections are filed; there is no discretion.

As we stated in Peterson v. Portland Metropolitan Boundary Comm., 21 Or. App. 420, 535 P.2d 577 (1975), the "triple majority" provision was enacted as an alternative to an election. It insulates annexation proposals from a vote of the residents in the territory to be annexed. Rivergate Residents Assn. v. Portland Metro Area, supra. Although the "triple majority" procedure does not enable landowners, as a distinct class, to initiate, vote on or veto an annexation, the landowners' consent is "binding" in the sense that it enables the city to choose to proceed with annexation without the approval of the electors. It is essential in determining that the electors will not be entitled to an election, even if the requisite number of them object timely. The advantage to landowners who avail themselves of the "triple majority" procedure is that they may achieve annexation of all of the property in the territory proposed to be annexed under circumstances in which a majority of the electors in the territory oppose the annexation. That advantage is substantial enough to be treated as a "privilege" under the Oregon Constitution.

The city urges that, when the "triple majority" provision is viewed in the context of the various methods of annexation, it becomes apparent that the provision does not grant to landowners any privilege not granted to nonlandowners on equal terms. However, as we view the statutory scheme, it is only when we examine all of the methods of accomplishing "minor boundary changes" that the true one-sidedness of the "triple majority" process becomes apparent. Although landowners and nonlandowner electors alike have the right to petition the boundary commission directly for annexation, ORS 199.490(1)(b) and (c), the consent process goes a step beyond. It permits a "triple majority" of the landowners, regardless of whether they are electors registered in, or even residing in, the territory to be annexed, to decide in favor of annexation, submit their consents to the governing body and thereby foreclose the election process if the proposed annexation is approved. No similar privilege is accorded to electors who are not landowners. The state's justification for denying that privilege to nonlandowners is, presumably, its interest in eliminating the administrative burden of an election "where consent procedures had already established that annexation was the clear will of the property owners in the affected territory." Peterson v. Portland Metropolitan Boundary Comm., supra, 21 Or App at 429. Applying the "balancing" test described in Olsen v. State ex rel Johnson, 276 Or. 9, 19, 554 P.2d 139 (1976); see also Planned Parenthood Assn. v. Dept. of Human Res., 63 Or. App. 41, 56, 663 P.2d 1247 (1983), aff'd 297 Or. 562, 687 P.2d 785 (1984), we conclude that that justification is not sufficient when it is weighed against the privilege to vote in a matter of general concern to electors registered in the territory to be annexed and that the "triple majority" provision violates Article I, section 20, of the Oregon Constitution.

Our reasoning is supported by the analysis under the federal Equal Protection Clause. There is no federal constitutional right to vote on annexation matters; the fixing of municipal boundaries is a state legislative function, Hunter v. City of Pittsburgh, 207 U.S. 161, 178, 28 S Ct 40, 52 L Ed 151 (1907), and we assume, without deciding, that the Oregon Constitution confers no greater right. However, once the legislature creates a right to vote on an annexation matter, it may not restrict that right on grounds other than age or residence without a showing that the restriction furthers a "compelling state interest." Hill v. Stone, 421 U.S. 289, 95 S Ct 1637, 44 L Ed 2d 172 (1975).

As respondents have noted, courts have approved statutory schemes containing alternate methods of annexation, some of which provide for election and some of which do not. Carlyn v. City of Akron, 726 F.2d 287 (6th Cir 1984); Adams v. City of Colorado Springs, 308 F. Supp. 1397 (D Colo), aff'd 399 U.S. 901, 90 S Ct 2197, 26 L Ed 2d 555 (1970); Weber v. City Council of Thousand Oaks, 9 Cal.3d 950, 109 Cal Rptr 553, 513 P.2d 601 (1973). However, no cases are cited, and we have found none, that have upheld a statutory scheme that provides that a binding election can be foreclosed by the voice of the landowners in the territory.

The cases involving the right to petition for annexation are distinguishable. Berry v. Bourne, 588 F.2d 422, 424-25 (4th Cir 1978); Goodyear Farms v. City of Avondale, 148 Ariz. 216, 714 P.2d 386 (1986); Doenges v. City of Salt Lake City, 614 P.2d 1237 (Utah 1980). They hold that the right to petition for annexation is not analogous to the right to vote and that unequal treatment in that context need only be rationally explained. Goodyear Farms v. City of Avondale, supra. In each case, a government body was ultimately responsible for determining whether the city would or would not annex the territory. The petitioners had been given no final say in the outcome of the annexation and had no right to vote on the final decision of the governing body.

Here, similarly, the consent process does not require the city or the boundary commission to take any action. However, the consent process affects the resident electors' right to cast a final and binding vote on the boundary commission's decision if it approves the proposed annexation. In fact, the only effect of the consent process is to foreclose all of the resident electors in the affected territory from voting on an annexation proposal ultimately submitted by the city to the boundary commission and approved by the latter. The "triple majority" process enables landowners to "veto," in advance, the electors' possible rejection of annexation. Because the landowners, under the "triple majority," have expressed their approval, a majority of the electorate in the territory affected will never have the opportunity to cast its in opposition.

In Seattle v. State, 103 Wn.2d 663, 694 P.2d 641 (1985), the statute under consideration provided that annexation decisions of the boundary commission were subject to vote; however, the right to vote could be blocked by the filing of a petition by 75 percent of the landowners in the affected area. The court reasoned that, although many statutory schemes giving property owners greater say in annexation matters have been upheld, when the final decision is made by election different considerations apply. The court stated that, once the state has chosen to submit an annexation question to a vote,

"[t]he State may not restrict the vote to property owners either directly, through limitations on the right to vote, or indirectly, by giving a particular class the power to prevent an election." 103 Wn. 2d at 673.

See also Hayward v. Clay, 573 F.2d 187 (4th Cir), cert den 439 U.S. 959 (1978); Curtis v. Board of Supervisors, 7 Cal.3d 942, 104 Cal Rptr 297, 501 P.2d 537 (1972); Levinsohn v. City of San Rafael, 40 Cal.App.3d 656, 115 Cal Rptr 309 (1974). The Washington case was decided under the Washington and federal constitutions. The same reasoning and result should obtain here.

Accordingly, we hold that the "triple majority" provision grants to landowners in the affected territory a privilege not granted to nonlandowners residing in the territory, the justification for which is outweighed by the detriment to nonlandowners that the classification creates. ORS 199.490(2) violates Article I, section 20, of the Oregon Constitution; it is, however, severable from the remainder of the statute.
