OPINION
¶ 1 Appellant Benson Hospital challenges the superior court’s grant of summary judgment in favor of appellee Abdulkadir Hourani in his appeal of the Hospital’s suspension of his hospital privileges. The Hospital also argues that the court erred by denying its cross-motion for summary judgment. We affirm the court’s denial of the Hospital’s motion, but reverse the granting of Hourani’s motion, finding that factual issues precluded summary judgment.
¶2 The procedural facts relevant to this appeal are undisputed. Abdulkadir Hourani is a board-certified, pulmonary critical-care specialist licensed to practice medicine in Arizona. From 2000 to 2002, he was employed by EmCare, Inc., which contracted with Benson Hospital to provide it emergency room physicians. In December 2000, the Hospital’s Medical Staff Executive Committee began investigating the quality of Houra-ni’s care at the Hospital and subsequently voted to recommend to the Governing Board that it revoke Hourani’s privileges to practice medicine at the Hospital. The Executive Committee informed Hourani of its decision, and Hourani requested a hearing. After the hearing, the hearing officer issued a report, stating that, of the eight cases discussed in his report, “variances” had occurred in three of the cases in which “the care varie[d] from the norm that has been established in Emergency Medicine.” However, the hearing offi- *430 eer made no official recommendation to revoke Hourani’s hospital privileges, stating at the hearing that “it is up to the Medical Staff to decide whether privileges are revoked or not revoked.” After considering the hearing officer’s report, the Executive Committee remained in favor of recommending to the Governing Board that it revoke Hourani’s privileges.
¶ 3 Hourani appealed the Executive Committee’s recommendation to the Appellate Review Committee. After a hearing, the Appellate Review Committee adopted the Executive Committee’s recommendation for revocation. The Governing Board subsequently accepted this recommendation and revoked Hourani’s privileges to practice medicine at Benson Hospital. Hourani sought injunctive relief from the superior court, arguing that the Hospital’s proceedings had denied him due process. Hourani moved for summary judgment, and the Hospital cross-moved for summary judgment. The superior court denied the Hospital’s motion but granted Hourani’s motion and ordered that his privileges be reinstated.
DENIAL OF SUMMARY JUDGMENT
¶4 Benson Hospital first argues that the superior court erred as a matter of law in denying its cross-motion for summary judgment, in which it had argued A.R.S. § 36-445.02(B) required the court to affirm a revocation of privileges that is based on substantial evidence. Although the denial of summary judgment is usually not an appeal-able order,
Bothell v. Two Point Acres, Inc.,
¶ 5 Section 36-445, A.R.S., requires licensed hospitals to have their medical staffs evaluated through peer review. In order to “encourage full and frank discussions and decision-making” in a process that can be both time consuming and contentious,
Scap-patura v. Baptist Hospital,
No hospital or outpatient surgical center and no individual involved in carrying out review or disciplinary duties or functions of a hospital or center pursuant to § 36-445 may be liable in damages to any person who is denied the privilege to practice in a hospital or center or whose privileges are suspended, limited or revoked. The only legal action which may be maintained by a licensed health care provider based on the performance or nonperformance of such duties and functions is an action for injunctive relief seeking to correct an erroneous decision or procedure. The review shall be limited to a review of the record. If the record shows that the denial, revocation, limitation or suspension of membership or privileges is supported by substantial evidence, no injunction shall issue. In such actions, the prevailing party shall be awarded taxable costs, but no other monetary relief shall be awarded.
¶ 6 The Hospital contended in its motion that the record contains substantial evidence supporting the revocation of Hourani’s privileges; therefore, it argued, regardless of any procedural violations, § 36-445.02(B) requires that “no injunction shall issue” and the courts must uphold the Governing Board’s decision. 1 Hourani countered that, *431 even if substantial evidence exists to support the Board’s decision, § 36-445.02(B) entitles him to injunctive relief to remedy the Hospital’s violation of its revocation procedures.
¶ 7 In interpreting a statute, our primary goal is to ascertain the legislature’s intent.
Ziemak v. Schnakenberg,
¶8 We find that language in § 36-445.02(B) could support either party’s interpretation. The statute provides that a physician may file “an action for injunctive relief seeking to correct an erroneous decision or procedure.” Id. However, it also states that an injunction shall not be issued if the decision “is supported by substantial evidence.” Id. Because those provisions could be interpreted as inconsistent, the language is ambiguous, and we must look beyond the language of the statute to determine the intent of the legislature.
¶ 9 The Arizona legislature enacted the state’s first statutorily mandated peer review requirement in 1971. 1971 Ariz. Sess. Laws, ch. 203, § 1. The statutes mandated peer review of physicians practicing in hospitals and provided immunity to those participating in the peer review process for decisions made “without malice and in good faith.”
Id.
They did not specifically provide for any judicial review of a final peer review decision. In 1984, the legislature amended § 36-445.02 and removed all liability for those involved in peer review activities, added hospitals themselves to the immunity provision, and only permitted a plaintiff to seek injunctive relief for an erroneous decision or procedure occurring during the peer review process. 1984 Ariz. Sess. Laws, ch. 119, § 1;
see Goodman v. Samaritan Health Sys.,
¶ 10 After the statute was enacted but prior to the amendment of § 36-445.02 in 1984, this court espoused the general rule that the exclusion of a physician from staff privileges in a private hospital was not subject to judicial review.
Peterson v. Tucson Gen. Hosp., Inc.,
¶ 11 In its 1984 revision, the legislature did not express any intent to limit a court’s authority to review a decision based on- a procedural defect; instead, the legislature appeared to codify the courts’ opinions by amending the statute to permit aggrieved parties to file “an action for injunctive relief seeking to correct an erroneous decision or procedure.” § 36-445.02(B). Furthermore, because we presume that the legislature did not include a provision that is “inert, trivial, [or] superfluous,”
Parrot,
¶ 12 We therefore conclude that § 36-445.02(B) permits a physician to bring an action to correct an erroneous decision or procedure and, if error is proved, entitles the physician to injunctive relief. Based on this conclusion, we reject the Hospital’s argument that the court erred in denying its motion for summary judgment.
GRANT OF SUMMARY JUDGMENT
¶ 13 The Hospital next argues that the court erred in granting Hourani’s motion for summary judgment, contending that questions of material fact exist that precluded judgment. A motion for summary judgment should only be granted if “there is no genuine issue as to any material fact and ... the moving party is entitled to judgment as a matter of law.” Ariz. R. Civ. P. 56(c), 16 A.R.S., Pt. 2;
see also Orme Sch. v. Reeves,
¶ 14 In granting Hourani’s motion, the court identified four defects in the Hospital’s revocation proceedings. The court found that there were no genuine issues of material fact on these violations and that Hourani was entitled to injunctive relief; the court ordered the Hospital to withdraw its revocation of Hourani’s privileges “unless and until proper procedures are followed in accordance with the Bylaws.”
¶ 15 The court’s first identified procedural defect, which the parties had not argued, was that the hearing officer had failed to recommend a sanction. 2 In his report to the Executive Committee, the hearing officer detailed Hourani’s alleged “variances” but did not recommend any specific action on them. The court found that, under the Hospital’s bylaws, the Executive Committee is bound to consider the hearing officer’s findings as well as recommendations. However, the court said: “In this case, the executive committee could not have considered what was not provided. The failure of the hearing officer to have included recommendations not only deprived the executive committee of the benefit of those recommendations, but similarly deprived the Appellate Review Committee and the Governing Board.”
¶ 16 The Appellate Review Committee is only required to consider the hearing officer’s report; it is not bound by it in any way. And Hourani did not present any evidence that he has suffered any prejudice from the hearing officer’s failure to recommend a sanction. Therefore, particularly in the absence of any timely objection by Hourani, we do not find that, as a matter of law, the hearing officer’s failure to make a recommendation invalidates the proceeding.
¶ 17 The court next found that the peer review process was procedurally flawed because Dr. Andrew Mayberry was appointed to the Appellate Review Committee as the practitioner peer. The Hospital’s bylaws require that the Appellate Review Committee *433 be composed of three members, two members of the Governing Board and one practitioner peer. The bylaws further provide that the practitioner peer “shall not be in direct economic competition with the affected Practitioner and shall be a peer of the Practitioner in a similar specialty under similar circumstances.”
¶ 18 The court noted that the record was not clear as to what Mayberry’s specialty is. Nevertheless, the court determined’that, in order to qualify as a peer “in a similar specialty under similar circumstances,” Mayber-ry had to be in direct economic competition with Hourani. Based on this analysis, the court concluded that Mayberry did not qualify as a practitioner peer under the Hospital’s bylaws and was ineligible to serve on the Appellate Review Committee.
¶ 19 The requirement that Mayberry have a “similar specialty” does not logically mean that he must practice emergency medicine or be in direct economic competition with Hour-ani. He could be in a similar specialty, satisfying the second criterion, without being in direct economic competition with Hourani, which would violate the first criterion. Furthermore, the record shows that Hourani was a contract physician employed by EmCare, Inc., whereas Mayberry was employed by Benson Hospital. And nothing in the record requires the conclusion that these two physicians competed for the same patients. Construing the facts and all reasonable inferences against Hourani,
see Link,
¶ 20 The court also found as a procedural flaw that Andrew Mayberry had served on both the Executive Committee and the Appellate Review Committee, noting that “it is implicit in the very nature of ‘appellate review' that the review be made by an impartial officer or group” and that “no one can be truly impartial in reviewing his or her own actions.” In essence, the court found that, as a matter of law, Mayberry’s participation in the Executive Committee’s investigation of Hourani’s actions disqualified him from later adjudicating this action on the Appellate Review Committee. But the Hospital’s bylaws contain no prohibition against a member of the Executive Committee serving on the Appellate Review Committee. Therefore, May-berry was only disqualified if his presence on both committees deprived Hourani of due process.

See
Holmes v. Hoemako Hosp.,
¶ 21 Due process of law contemplates a “‘fair trial in a fair tribunal.’”
United States v. Superior Court,
¶ 22 Hourani argues that these cases are distinguishable because Mayberry sat on both the Executive Committee that decided to bring charges and the Appellate Review Committee that reviewed the Executive Committee’s decision. But the principles announced in Withrow and DeGroot apply equally here. Because the Governing Board was the final decision-maker in revoking Hourani’s privileges, the fact that the prior proceeding was termed “appellate” is of no import, as it was merely preliminary to the Governing Board’s final decision.
¶ 23 Nevertheless, a plaintiff may challenge a decision maker’s impartiality by “demonstrat[ing] that the mind of the decision maker is ‘irrevocably closed’ on the particular issues being decided.”
Havasu Heights Ranch & Dev. Corp. v. Desert Valley Wood Prods., Inc.,
¶ 24 Hourani did not present any evidence that Mayberry had received information from an “extrajudicial source” or was unable to fairly evaluate the findings by the hearing officer and discuss the matter with other members of the Appellate Review Committee in deciding what sanction to impose. Therefore, Hourani failed to overcome the presumption of Mayberry’s “honesty and integrity.”
Pavlik,
¶ 25 In a supplemental citation of authority, Hourani relies on two cases to support his claim that Mayberry should have been disqualified. Hourani first cites
Yaqub v. Salinas Valley Memorial Healthcare System,
¶ 26 Hourani also cites Yaqub for the proposition that a disciplinary panel member should be precluded from “sitting on [an appellate] panel and reviewing its own decision made in a previous hearing.” Id. at 789. But the court made this statement in the context of quoting the trial court’s reasoning for rejecting the argument raised under a California statute, which prohibited individuals from serving dual roles. Accordingly, we find Yaqub inapplicable to this case.
¶ 27 Hourani’s second supplemental citation of authority is an unpublished district court opinion from Louisiana. Other than two exceptions that do not apply to this, case, unpublished decisions “shall not be regarded as precedent nor cited in any court.” Ariz. R. Civ.App. P. 28(c), 17B A.R.S. This prohibition extends to federal district court memorandum decisions.
See Walden Books Co. v. Dep’t of Revenue,
¶28 Finally, the court found that Dr. Carter Mayberry
4
should have recused himself from “any voice or vote” on the Governing Board when it voted to revoke Hourani’s privileges. The court’s ruling is unclear as to why Carter Mayberry should have recused himself, but Hourani defends the decision based on Mayberry’s participation as a member of the Executive Committee. Again, the bylaws do not prohibit a member from serving on both the Executive Committee and the Governing Board. And Hourani did not present any evidence that Mayber-ry’s participation on the Executive Committee “irrevocably closed” his mind on whether the Governing Board should revoke Houra-ni’s privileges.
Havasu Heights,
DISPOSITION
¶ 29 We affirm the superior court’s denial of the Hospital’s cross-motion for summary judgment. But, because we find as a matter of law that the unchallenged lack of a recommendation from the hearing officer was insufficient to invalidate the process and that questions of material fact exist on whether other procedural violations occurred during Hourani’s revocation proceedings, we reverse the judgment on this issue and remand this matter to the superior court for further proceedings.
Notes
. At the hearing before the superior court, the Hospital conceded that an "egregious" procedural violation would authorize injunctive relief. Neither the history of the statute nor its wording justifies any distinction between those procedural violations that are egregious and those that are material but not egregious.
. Hourani did not bring this defect or the other alleged defects to the attention of the hearing officer, the Appellate Review Committee, or the Governing Board. At any time during this process, all of the alleged defects could have been corrected. Hourani cannot allow procedural defects to continue and await the final outcome before complaining about them.
See DeGroot v. Ariz. Racing Comm’n,
But, as Hourani notes, the Hospital did not argue Hourani's waiver before the superior court. On appeal from summary judgment, an appellant may not advance new theories or raise new issues to secure reversal.
Mitchell v. Gamble,
. Although the Hospital does not dispute that Hourani was entitled to due process, we do not necessarily agree that the concept of constitutional due process applies to this situation. Other jurisdictions have also questioned this proposition.
See Pariser v. Christian Health Care Sys., Inc.,
. Carter Mayberry is the brother of Andrew May-berry.
