OPINION
¶ 1 In this appeal, we determine the constitutionality of Arizona Revised Statutes (A.R.S.) § 12-2602 (2000) under the equal protection and separation of powers clauses of the Arizona Constitution. Section 12-2602 outlines the circumstances that require plaintiffs to disclose preliminary expert opinion evidence for claims against licensed professionals. 1 We hold that A.R.S. § 12-2602 does not violate either equal protection or separation of powers. The trial court’s rulings are affirmed in all respects.
*126 BACKGROUND
¶ 2 Arlen M. Bertleson and Astrida S. Bertleson have lived near the TRW Vehicle Safety Systems, Inc. (TRW) plant in Mesa, Arizona since it opened in the early 1990s. By 1992, fires and explosions had begun to occur at that plant. According to the Bertlesons, contaminants released from these explosions and other emissions have harmed them.
¶ 3 In January 1998, the Bertlesons retained Sacks Tierney, P.A. (Sacks Tierney) to: (1) write a demand letter to TRW for compensation for damages to the Bertlesons, their real property, and their personal property, and (2) negotiate a possible settlement with TRW. Sacks Tierney attorney Andrew Lane de Mars (de Mars) delivered a demand letter to TRW in April 1998 and TRWs counsel responded. Sacks Tierney was involved in discussions with TRW about a possible resolution when the Bertlesons terminated the representation by Sacks Tierney. The Bertlesons later filed a complaint against Sacks Tierney, de Mars, and de Mars’ wife (collectively, defendants) alleging negligence and breach of contract. The Bertlesons subsequently dismissed the contract claim.
¶ 4 The Bertlesons failed to serve an initial certificate, as required by A.R.S. § 12-2602(A), stating whether expert testimony was necessary to prove their negligence claim against Sacks Tierney. When the parties exchanged Rule 26.1 disclosure statements, the Bertlesons failed to disclose an expert opinion concerning the standard of care or liability. Accordingly, defendants moved to compel disclosure of the Bertlesons’ preliminary expert opinion. After the deadline to respond had passed, the Bertlesons moved for a declaration that A.R.S. § 12-2602 was unconstitutional.
¶ 5 The trial court denied the Bertlesons’ motion to find the statute unconstitutional and granted defendants’ motion to compel the necessary expert opinions. No expert opinion was produced and the Bertlesons’ complaint was dismissed. This appeal followed.
DISCUSSION
A. Equal Protection
¶ 6 This court reviews de novo challenges to a statute’s constitutionality.
3613 Ltd. v. Dep’t of Liquor Licenses & Control,
¶ 7 The Equal Protection Clause of the Arizona Constitution provides:
No law shall be enacted granting to any citizen, class of citizens, or corporation other than municipal, privileges or immunities which, upon the same terms, shall not equally belong to all citizens or corporations.
Ariz. Const. art. 2, § 13. Any statute that “is aimed at limiting a fundamental right” or “discriminates among individuals based on a ‘suspect class’ ” is subject to strict scrutiny under this clause.
Ariz. Downs v. Ariz. Horsemen’s Found.,
1. Section 12-2602 Does Not Infringe upon a Fundamental Right
¶ 8 This court held that a prior version of A.R.S. § 12-2602 infringed upon a plaintiffs fundamental right to sue for damages for injuries and did not survive strict scrutiny.
See Hunter Contracting Co. v. Superior Ct.,
A. If a claim against a licensed professional is asserted in a civil action, the claimant or the claimant’s attorney shall *127 certify in a written statement that is filed and served with the claim whether or not expert opinion testimony is necessary to prove the licensed professional’s standard of care or liability for the claim.
B. If the claimant or the claimant’s attorney certifies pursuant to subsection A that expert opinion testimony is necessary, the claimant shall serve a preliminary expert opinion affidavit with the initial disclosures that are required by rule 26.1, Arizona rules of civil procedure. The claimant may provide affidavits from as many experts as the claimant deems necessary. The preliminary expert opinion affidavit shall contain at least the following information:
1. The expert’s qualifications to express an opinion on the licensed professional’s standard of care or liability for the claim.
2. The factual basis for each claim against a licensed professional.
3. The licensed professional’s acts, errors or omissions that the expert considers to be a violation of the applicable standard of care resulting in liability.
4. The manner in which the licensed professional’s acts, errors or omissions caused or contributed to the damages or other relief sought by the claimant.
F. The court, on its own motion or the motion of the licensed professional, shall dismiss the claim against the licensed professional without prejudice if the claimant fails to file and serve a preliminary expert opinion affidavit after the claimant or the claimant’s attorney has certified that an affidavit is necessary or the court has ordered the claimant to file and serve an affidavit.
As revised, A.R.S. § 12-2602 infringes upon no fundamental right.
a. The Statute Does Not Mandate An Expert Opinion
¶ 9 The
Hunter
court’s primary objection to the statute was that it required plaintiffs to hire an expert witness even when one would not be necessary.
¶ 10 In any event, the Hunter court’s objection is not at issue in this case. Here, the Bertlesons do not even challenge that expert testimony would be necessary to support their malpractice claim against Sacks Tierney. Therefore, A.R.S. § 12-2602(A) does not impose any additional burden upon the Bertlesons.
b. The Statute Does Not Restrict the Plaintiffs’ Choice of Experts
¶ 11 In
Hunter,
we also found problematic the statute’s requirement that the expert providing the affidavit “practice in the same discipline as the defendant.”
c. The Statute Does Not Require Service of an Expert Affidavit with the Complaint
¶ 12 Another ground for invalidating the earlier version of A.R.S. § 12-2602 was that it required the plaintiff to file and serve the expert affidavit with the complaint. Specifically, the prior opinion reflected concerns as to the timing of disclosure and the lack of flexibility afforded to the trial court.
Hunter,
¶ 13 We disagree. The current version states that if expert testimony is required, the plaintiff need not file the affidavit until the time for initial disclosures. A.R.S. § 12-2602(B). Moreover, the plaintiff may delay service by demonstrating good cause to the trial court or by stipulating with the parties to the claim. A.R.S. § 12-2602(C). Under *128 A.R.S. § 12-2602(G), the plaintiff may also supplement the expert’s preliminary opinion affidavit and the claim as necessary. In sum, the legislature has cured the stated problem of requiring the service of an affidavit with the complaint and has provided the trial court with ample flexibility to modify the timing of its disclosure.
¶ 14 In any event, the issue of premature affidavit disclosure did not arise in this case. The Bertlesons received a disclosure from defendants containing de Mars’ version of the facts before the trial court ordered them to supply the missing affidavit. The Bertlesons never explained what additional information they required and never moved for an extension of time to complete discovery under A.R.S. § 12-2602(0). Having failed to avail themselves of the statute’s flexibility, the Bertlesons are in no position to complain now about their need for additional information.
d. The Statute Does Not Mandate Dismissal
¶ 15 Finally, the
Hunter
court found the earlier version of the statute invalid because it mandated dismissal when a plaintiff failed to serve an expert opinion affidavit with the complaint.
¶ 16 The statute permits dismissal after it is admitted by the plaintiff or determined by the court that expert opinion testimony is required. A plaintiff cannot lose a claim by being required to produce evidence she or he would otherwise not have had to produce. Dismissal under these circumstances no more violates the constitution than dismissal based upon a statute of limitations or summary judgment.
See Rutledge v. State,
2. Section 12-2602 Does Not Implicate a Suspect Class
¶ 17 The Bertlesons appear to contend that the statute violates the equal protection clause by discriminating between licensed professionals and other defendants. No suspect class is at issue here.
See In re Hoover,
3. A.R.S. § 12-2602 Is Rationally Based and Furthers a Legitimate State Interest
¶ 18 Because A.R.S. § 12-2602 does not implicate a fundamental right or a suspect class, we must uphold it if the Arizona Legislature had a rational basis for enacting it.
See Goodyear Farms v. City of Avondale,
¶ 19 In
Hunter,
we accepted for purposes of argument that the state has a compelling interest in protecting licensed professionals from frivolous lawsuits.
B. Separation of Powers
¶20 The Bertlesons further argue that A.R.S. § 12-2602 violates the Separation of Powers Clause of the Arizona Constitution by encroaching upon the Arizona Supreme Court’s rulemaking authority. We disagree.
¶ 21 Article 3 states:
The powers of the government of the State of Arizona shall be divided into three separate departments, the Legislative, the Executive, and the Judicial; and, except as provided in this Constitution, such departments shall be separate and distinct, and no one of such departments shall exercise the powers properly belonging to either of the others.
In addition, Section 5 of Article 6 states that the supreme court “shall have ... [p]ower to make rules relative to all procedural matters in any court.” The legislature may not enact “a statutory rule that ‘conflict[s with] or ... tends to engulf a general rule ... ’ adopted by the court pursuant to its exclusive power to make [procedural] rules.”
State v. Nihiser,
¶22 Nothing in A.R.S. § 12-2602 is in conflict with or engulfs our supreme court’s rulemaking power. Contrary to the Bertlesons’ allegations, neither Rule 26.1 nor Rule 16(c) require disclosures at a time different than what is provided for in A.R.S. § 12-2602. The statute provides for disclosure of preliminary expert opinions — consistent with Rule 26.1(a) — at the time for serving disclosure statements in accordance with Rule 26.1(b)(1). The Rule 16(e) pretrial conference procedures for medical malpractice cases also pose no conflict. The current version of A.R.S. § 12-2602 supplements the procedural rules and does not violate the separation of powers clause.
See Nihiser,
CONCLUSION
¶ 23 For the above stated reasons, we affirm the trial court’s determination that A.R.S. § 12-2602 is constitutional and affirm the dismissal of the Bertlesons’ negligence claim.
