OPINION
¶ 1 The ultimate issue presented by this case is whether it is constitutional for the Arizona state legislature to require the consent of a proximate municipality before an area may incorporate. We conclude that the statute requiring such permission as a predicate to municipal incorporation, Ariz.Rev. Stat. (“A.R.S.”) § 9~101.01(B)(1) (1996), is constitutional, and we therefore affirm the superior court’s judgment dismissing the appellants’ contrary contentions.
FACTS and PROCEDURAL HISTORY
¶ 2 Since 1961, A.R.S. sections 9-101 (Supp.2000) and 9-101.01 have outlined the procedure for a municipality’s incorporation.
See City of Tucson v. Woods,
¶ 3 However, A.R.S. section 9-101.01 modifies these procedures if an “urbanized area” is involved. That statute states, in relevant part:
A. Notwithstanding any other provision of law to the contrary, all territory within six miles of an incorporated city or town, as the same now exists or may hereafter be established, having a population of five thousand or more as shown by the most recent federal census, and all territory within three miles of any incorporated city or town, as the same now exists or may hereafter be established, having a population of less than five thousand as shown by the most recent federal census is declared to be an urbanized area.
B. No territory within an urbanized area shall hereafter be incorporated as a city or town, and the board of supervisors shall have no jurisdiction to take any action upon a petition to incorporate a city or town within such area, unless:
1. There is submitted with the petition for incorporation a resolution adopted by the city or town causing the urbanized area to exist approving the proposed incorporation; or
*513 2. There is filed with the board of supervisors an affidavit stating that a proper and legal petition has been presented to the city or town causing the urbanized area to exist requesting annexation of the area proposed for incorporation and such petition has not been approved by a valid ordinance of annexation within one hundred twenty days of its presentation.
¶ 4 In April 1997, the Arizona Legislature enacted Laws 1997, Chapter 204, Section 2 (“1997 Law”), the sole purpose of which was to suspend the consent requirement of A.R.S. section 9 — 101.01(B)(1) in Pima County between July 21, 1997, and July 15,1999. This prompted the proponents of incorporating the areas known as Tortolita and Casas Adobes to file incorporation petitions with the Pima County Division of Elections. 1 Both Tortolita and Casas Adobes are within the relevant distance of the City of Tucson and the Towns of Maraña and Oro Valley to qualify as “urbanized areas.” Tucson responded by immediately filing a complaint in Pima County Superior Court challenging the 1997 Law as a special or local law barred by the Arizona Constitution.
¶ 5 The superior court ruled that the 1997 Law was constitutional. Thus, the members of the Pima County Board of Supervisors, relying on the 1997 Law and therefore without the consent otherwise required by A.R.S. section 9-101.01(B)(l), declared Tortolita incorporated and called for an incorporation election for Casas Adobes.
¶ 6 Shortly thereafter, though, we concluded in
Woods
that the 1997 Law was a special or local law contrary to the Arizona Constitution, Article 4, Part 2, Section 19.
¶ 7 As those proceedings continued, the case again was brought to this court by petition for special action review. City of Tucson v. Alfred (Pima County), 1 CA-SA 98-0281 (Dec. Order, Nov. 24, 1998). Accepting jurisdiction but denying relief, we ruled that the superior court had correctly interpreted the opinion in Woods to permit federal constitutional challenges to A.R.S. section 9-101.01 to be presented by Pima "County, the Pima County Board of Supervisors, the Committee to Incorporate [the Village of Casas Adobes] and the Committee to Incorporate the Town of Tortolita. Id.
¶ 8 Upon further proceedings, the supeiior court issued a series of thoughtful and thorough minute entries. It declared that the Town of Oro Valley was permitted to intervene; that Pima County, the members of its Board of Supervisors, Tortolita and Casas Adobes lacked standing to bring federal constitutional claims challenging a state statute; that the Committee to Incorporate the Town of Tortolita, Cheryl L. Wiener, Ronald K. Wiener, Joan L. Eerkes and David L. Eerkes lacked standing and a justiciable claim of a violation of the Guaranty Clause of the United States Constitution; that the Committee to Incorporate [the Village of Casas Adobes], Jane Madden, Scott Nelson and Lowell Lowe, and the Committee to Incorporate the Town of Tortolita, Cheryl L. Wiener, Ronald K. Wiener, Joan L. Eerkes and David L. Eerkes lacked standing to challenge A.R.S. section 9-101.01(B)(2); and that claims against the State of Arizona pursuant to 42 United States Code section 1983 filed by the Committee to Incorporate [the Village of Casas Adobes], Madden, Nelson and Lowe were not permitted because of the Eleventh Amendment to the United States Constitution. The court refused to consider whether Tucson’s decision not to consent to Tortolita’s incorporation was one of bad faith because such an inquiry would require an examination of the motivation of the legislative branch by the judicial branch of government, an inquiry barred by the state and federal constitutional requirements of the separation of powers among the three branches of government.
*514 ¶ 9 Ultimately, the superior court held that A.R.S. section 9-101.01(B)(l) is constitutional because it neither violates federal constitutional guarantees of equal protection, procedural or substantive due process, the “right to self-determination” or any of the rights enshrined by the First Amendment to the United States Constitution, nor does it have an adverse impact on the right to vote. Rather, the court concluded, it bears a rational relationship to a legitimate state interest against the Balkanization of its counties. Accordingly, judgment was granted in favor of Tucson, the State and Oro Valley. It is from this judgment that there now is a further appeal, presenting the following issues:
1. Whether Pima County and Tortolita have standing;
2. Whether the superior court abused its discretion by permitting Oro Valley to intervene;
3. Whether A.R.S. section 9 — 101.01(B)(1) violates the voting-rights doctrine of the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution;
4. Whether there has been a violation of the appellants’ right to petition the government for a redress of their grievances pursuant to the First Amendment to the United States Constitution; and
5. Whether Tucson acted in bad faith in refusing to consent to Tortolita’s incorporation.
DISCUSSION
A. Standing of Pima County and Tortolita
¶ 10 Tucson argues that, as state political subdivisions, Pima County and Tortolita are without standing to challenge the constitutionality of A.R.S. section 9-101.01. “Whether appellants have standing to sue is a question of law we review de novo.”
Alliance MaraNa v. Groseclose,
¶ 11 The issue of standing is not jurisdictional in Arizona but, rather, “solely a rule of judicial restraint.”
Woods,
¶ 12 Just as we held in Woods that Tucson had a direct stake in determining whether the 1997 Law was constitutional, id., so too does Pima County have a direct stake in determining whether A.R.S. section 9-101.01(B)(1) is constitutional. Accordingly, Pima County has standing.
¶ 13 Tortolita is a different matter because we decided in Woods that it never was validly incorporated, and, therefore, it does not exist. However, if we deny it standing, the would-be town cannot challenge the constitutionality of the very statute, A.R.S. section 9-101.01, which governs its incorporation. Our resolution of this quandary is to treat Tortolita as existing insofar as its electors complied with the statute for the purpose of challenging the constitutionality of the statute.
¶ 14 Furthermore, even if Pima County and Tortolita lack standing, there remain parties with unequivocal standing who offer the same arguments. Thus we address the constitutional challenges to A.R.S. section 9-101.01.
See Cutter Aviation, Inc. v. Arizona Dep’t of Revenue,
*515 B. Intervention of Oro Valley
¶ 15 Tortolita complains that the superior court should not have permitted Oro Valley to intervene. We review the propriety of the court’s decision for an abuse of its discretion.
Purvis v. Hartford Acc. and Indent. Co.,
¶ 16 To protect interests similar to those of Tucson, Oro Valley sought to intervene in the litigation upon remand from this court. For reasons comparable to those we expressed with regard to Tucson in
Woods,
1117 Even if the superior court had erred, the error would have been harmless. Because of the correspondence between Oro Valley’s involvement and that of Tucson, there was no prejudice to Tortolita in allowing the intervention of Oro Valley.
Purvis,
C. Equal Protection and the Right to Vote for Municipal Incorporation
¶ 18 The appellants contend that A.R.S. section 9-101.01(B) violates the voting-rights doctrine of the Equal Protection Clause of the Fourteenth Amendment of the United States Constitution. The specific argument is that the petition process of A.R.S. section 9-101 triggers a fundamental right to vote and that the consent requirement in section 9-101.01(B) unconstitutionally burdens this right by giving a veto to the city or town that caused the urbanized area to exist. The constitutionality of a statute is a question of law we review de novo.
City of Tucson v. Rineer,
¶ 19 There is no constitutional right to vote for municipal incorporation.
Hussey v. City of Portland,
Municipal corporations are political subdivisions of the state, created as convenient agencies for exercising such of the governmental powers of the state as may be intrusted to them____The number, nature, and duration of the powers conferred upon these corporations and the territory over which they shall be exercised rests in the absolute discretion of the state.... The state, therefore, at its pleasure, may ... take without compensation such property, hold it itself, or vest it in other agencies, expand or contract the territorial area, unite the whole or a part of it with another municipality____ All this may be done, conditionally or unconditionally, with or without the consent of the citizens, or even against their protest. In all respects the state is supreme, and its legislative body, conforming its action to the state Constitution, may do as it will, unrestrained by any provision of the Constitution of the United States.
Hunter,
¶ 20 In a manner consistent with this hierarchy of political entities, the Arizona Constitution in Article 13, Section 1, gives the legislature plenary power over the “methods and procedures for [municipal] incorporation.”
State ex rel. Pickrell v. Downey,
¶ 21 As a general proposition, absent a suspect classification or fundamental interest, review pursuant to the Equal Protection Clause is limited to whether a statute is rationally related to a legitimate state purpose.
Heller v. Doe,
¶22 The
Goodyear
case involved a statute requiring that petitions be signed by at least one-half of the affected property owners before a city could annex an area by ordinance.
¶ 23 As was true in Goodyear, the petitions requesting a declaration of incorporation or an election for that purpose, like those for a municipal annexation of an area, are not determinative but only a prerequisite for action by the legislative body, the city in Goodyear and the county board of supervisors in this case. The difference as argued by the appellants is that the petitions were advisory in Goodyear whereas, in this case, the petitions require the board of supervisors to act. That is only partially true, though, because the filing of lawful petitions is but one of two prerequisites for legislative action. In other words, there are two statutory prerequisites before the county board of supervisors may proceed to declare or to call an election to declare an area incorporated: the requisite number of lawful petitions and the agreement of the neighboring city or town. The petitions themselves are of no effect. Only if and when both of the statutory conditions are met will there be legislative action. Thus, as was true in Goodyear, the petition process does not in any legally significant sense equate to an election.
¶24 The appellants rely upon
Curtis v. Board of Supervisors,
When persons owning a majority of assessed valuation of land within the proposed City of Rancho Palos Verdes filed a written protest, the Los Angeles County Board of Supervisors, pursuant to Government Code section 34311, refused to call an incorporation election. The crux of petitioners’ plea to us is that section 34311 violates the Constitution; upon this basis they seek [a] mandate to compel the board to resume incorporation proceedings. We have concluded that the section is, indeed, unconstitutional under the equal protection clause of the Fourteenth Amendment to the United States Constitution and the correlative provisions of the California Constitution.
Id.
¶ 25 The
Curtis
case is not analogous for the reasons given by the court in
Goodyear.
¶26 For similar reasons as distinguish
Curtis,
the petition process at issue differs substantially from that in
Hussey,
¶27 In
Sherwood,
the Oregon Court of Appeals distinguished
Hussey
on the basis that, since the government had “authorized an election, it could not condition the right to vote
in that election
without a compelling justification.”
¶ 28 The appellants then argue that the Equal Protection Clause is violated because only those within the “urbanized area” need to acquire a city’s consent. They also contend that, if this proposition is rejected, Pima County ought to be considered the relevant voting area and that the classification requiring those within the six-mile range to obtain consent discriminates within Pima County.
¶ 29 The Equal Protection Clause does not preclude the establishment of distinct classes within a geographic area if the classifications are reasonably related to a legitimate state interest and all persons within the class are treated equally.
Martin,
¶ 30 Given that no improper distinction is being made by the Arizona legislature between and among classes of persons within the relevant area, the statute does not implicate, let alone burden, the Equal Protection Clause’s right to vote. Accordingly, we analyze the statutory scheme of A.R.S. sections 9-101 and 9-101.01 using a rational-basis standard.
See Holt,
¶ 31 The state, as was said above, has the power to shape municipalities and to protect the interests of those within existing cities and towns concerning the formation of new political subdivisions. As the superior court concluded, paraphrasing
Snyder,
It is obvious from the reading of [section] 9-101.01 that the intent of the legislature in enacting it was to grant some control to existing cities and towns with regard to proposed incorporations of areas close to their boundaries. The result of [appellants’] construction would be a proliferation of small towns within a short distance of large cities and the attendant inefficient and uneconomical provision of government services. That does not appear to have been the intent of the legislature.
And, as had the court in
Snyder,
we noted in
Woods
that the intent of A.R.S. section 9-101.01 was “for orderly development and efficient municipal administration.”
D. First Amendment Right to Petition Government
¶ 32 Certain appellants complain of a violation of the right guaranteed them by the First Amendment to the United States Constitution to petition the government for a redress of their grievances. They misunderstand this right.
¶ 33 “The right to petition bars state action interfering with access to the legislature, the executive branch and its various agencies, and the judicial branch,”
Ruiz v. Hull,
E. Tucson’s Refusal to Consent to Tortolita’s Incorporation
¶34 Tortolita argues that Tucson acted in bad faith in refusing to consent to Tortolita’s incorporation, thus making A.R.S. section 9 — 101.01(B)(1) unconstitutional as applied. However, Tucson’s exercise of consent pursuant to section 9 — 101.01(B)(1) is a delegated legislative duty,
Pickrell,
¶ 35 Additionally, in
Woods,
we held that A.R.S. section 9-101.01 is not unconstitutional in delegating to “urbanized areas” the discretion whether to grant consent to neighboring municipal incorporations.
CONCLUSION
¶ 36 The judgment is affirmed. This case is remanded to the superior court for such further proceedings as remain necessary.
Notes
. The incorporation declaration for Tortolita was governed by the requirements of A.R.S. section 9-101 (A) because the incorporation proponents gathered petitions signed by more than two-thirds of the eligible electorate. The incorporation election of Casas Adobes was governed by section 9-101(B) because the proponents of its incorporation gathered petitions signed by more than ten percent of that electorate.
. Hereafter, a reference to "Pima County” yviU refer also to the members of the Pima County Board of Supervisors. Similarly, we will refer to the Town of Tortolita, the Committee to Incorporate the Town of Tortolita, Cheryl L. Wiener, Ronald K. Wiener, Joan L. Eerkes and David L. Eerkes collectively as "Tortolita."
