OPINION
This is an appeal from an order enjoining the City of Tucson and its Clerk from placing an initiative on the November 1997 ballot. We review the trial court’s ruling pursuant to our appellate jurisdiction under A.R.S. § 19-122(C). On September 13, 1997, after considering the submitted briefs, we vacated the trial court’s order and advised the Clerk that the initiative could be placed on the general election ballot. We further indicated that this opinion would follow.
FACTS AND PROCEDURAL HISTORY
Signed on April 4, 1997, A.R.S. § 23-362 declared minimum wage a matter of statewide concern and forbade any governmental subdivision from establishing a minimum wage in excess of thе federal minimum wage. Some six months before the statute was enacted, interested parties had already commenced a signature drive for the “Tucson Livable Wage Initiative.” If passed, the initiative would have required Tucson employers to pay workers a minimum wage of $7.00 per hоur effective January 1, 1998. On August 1, 1997, the City Clerk certified to the Mayor and City Council that the initiative satisfied all state and city procedural requirements and was therefore a qualified proposal. Thus, on August 4, the City Council placed the initiative on the ballot. On August 11, initiative opponents Brian Winkle and Frank Beauvais (“Appellees”) filed a complaint in Pima County Superior Court alleging that the proposed initiative contained both procedural and substantive defects. The trial judge found no procedural defect but enjoined the initiative as substantively preempted by A.R.S. § 23-362. The initiativе proponents appealed, asking this court to consider one issue: Whether a court can enjoin a proposed initiative on the basis that *415 its content, if passed, may be preempted by state law.
The fundamental question is whether the judicial power granted by the Arizona Constitution permits our courts to examine the substance of an initiative and remove it from the election ballot. Initiative opponents contend that even before its passage, the initiative is ripe for preemption review. Concluding our constitution forbids this type of judicial interference with the people’s power to legislate, we hold that the initiative is not ripe for review.
DISCUSSION
A. Separation of powers
Arizona’s constitution ensures the proper distribution of power among our three separate and distinct branches of government.
Fairness & Accountability in Ins. Reform v. Greene,
“This court has carefully observed these dividing lines, particularly in сases where we are asked to prohibit or require legislative action.”
Fairness & Accountability,
Only two years after statehood, this court held that determining an initiative’s validity before the voters had an opportunity to vote on it would
be tantamount to claiming the power of life and death over every initiated measure by the people. It would limit the right of the people to propose only valid laws, whereas the other lawmaking body, the Legislature, would go untrammeled as to the legal soundness оf its measures.
State v. Osborn,
As a true reflection of democratic principles, Arizоna citizens are not precluded from legislating on any issue, even though the legislation might conflict with the Arizona Constitution or state law.
Iman v. Bolin,
B. Judicial review
Appellees attempted to derail an initiative proposal prior to public vote. Because the election had not yet occurred, ripeness was at issue.
Cf. Tilson,
*416
Preelection review of the substantive validity of an initiative may arguably be more efficient, but we have considered and rejected this possibility. In
Williams v. Parrack,
this court held that, “[w]hile it may entail considerable expense to submit the ordinance to a vote of the people, this court has not the authority to pass upon the validity or invalidity of said ordinance before its enactment into law.”
Prior to passage, this court will consider only procedural defects in form that bear directly on the integrity of the election process. The statute governing initiatives requires only that a petition be legally sufficient to receive constitutional protection and be placed on the ballot.
See
A.R.S. § 19-122(C). We first construed this requirement in
Osborn,
in which we held that an initiative was legally sufficient so long as it was not fraudulent and complied with the form and signature requirements.
1. Procedural defects in form
This court has recognized only two kinds of procedural defects in intiative petitions. The first is a failure to structurally comply with A.R.S. §§ 19-101 to 19-144. For example, the petition could lack the requisite number of signatures or fail to comply with publication requirements.
See Fairness & Accountability,
The second arises when text of the initiative does not comprise legislation. because it fails to enact anything.
Saggio v. Connelly,
The trial judge found no procedural defects. Nor do Appellees challenge the form of the initiative. See Ariz. Const. art. XII, § 1; A.R.S. §§ 19-101 to 19-144. Additionally, Appellees do not contend that the proposal does not constitute legislation; in fact, it is precisely because of its potential legislative effect that Appellees seek to block it. At this point, any inquiry beyond procedural defect would prematurely examine the measure’s substantivе validity.
2. State law preemption of a proposed initiative
Appellees urge us to undertake a preelection preemption analysis and disqualify the initiative. Preemption requires a two-step analysis: 1) whether the subject matter is one of statewide concern, and 2) whether the state legislation has appropriated the field.
See State v. Mercurio,
To bе preempted, a municipal ordinance must actually conflict with governing state law.
See City of Prescott v. Town of
*417
Chino Valley,
Appellees cite two zoning cases from this court to support preelection review of an initiative.
See City of Scottsdale v. Superior Court,
The State Zoning Enabling Act expressly delegates zoning powers to other levels of government, including the governing body of an incorporated city. A.R.S. §§ 9-461 to 9-463.06, 11-801 to 11-874. Zoning ordinances cannot be passed by initiative without circumventing the constitutionally required notice and hearing.
See City of Scottsdale,
Additionally, Appellees cite
Robertson v. Graziano,
*418 Thus, neither Saggio nor Robertson permits a preemption аnalysis to determine whether the law will be valid if it passes. Saggio permits only procedural scrutiny of an initiative’s text to determine whether it is entitled to protection as legislation. When a proposed initiative comprises legislation, it. is improper to subject it to substantive analysis before enactment.
C. Policy concerns
Finally, policy considerations support judicial restraint. As a jurisprudential matter, this court has a strong interest in promoting judicial economy. Review of a proposal that may or may not become law amounts to no more than an advisory opinion. Once сommitted to this practice, the judiciary would be inundated with unnecessary preelection challenges. 4
Second, this court should not create an impediment to the exercise of one of our state government’s bedrock institutions. Grassroots democracy, exercised by initiаtive, is not always an efficient process; however, there are clear benefits to allowing the public to vote on an initiative, even though its validity may be questioned if it passes. In a democracy, the process itself is often as valuable as the result. A vote to enact lеgislation expresses more than a current whim of the people; it expresses the voters’ preferred rule of governance. Ultimately, preemption may prevent enforcement of a law, but it cannot forbid the voters from voicing their views of a legislative propоsal via the initiative process. If this process is deemed a waste of taxpayers’ time or money, then the laws governing initiatives may be altered by legislative process, not by judicial decision.
CONCLUSION
Challenges to any initiative based on its substance must wait until enactment. If and when an initiative passes, a court may then determine whether its contents are preempted by A.R.S. § 23-362 or rendered invalid by any state law or constitutional clause then existing.
Notes
. This court held in
Saggio
that the text of the initiative to dissolve Apache Junction did not "indicate whether it is an ordinance enacting nеw legislation, an amendment to an existing ordinance, or the repeal of an existing ordinance ____ The proposed measure is more in the nature of a demand for a public opinion poll by election. The form of the measure, however, is not legislation. It does not enаct anything.”
. A.R.S. § 23-362 entitled “Minimum wage; prohibition” reads:
A. The legislature declares that the establishment of a uniform minimum wage is a matter of statewide concern.
B. No political subdivision of this state may establish, mandate or otherwise require a minimum wage that exceeds the federal minimum wage prescribed in 29 United States Code § 206.
. While the voters may not initiate zoning, they still can call a referendum election on an ordinance, as the hearing to protect due рrocess rights of property owners has already occurred at the pre-approval stage.
Queen Creek Land & Cattle v. Yavapai County Bd. of Supervisors,
. In the present case, for example, the proposal was defeated in the November 1997 election.
