BACKGROUND
¶ 1 Defendant Sean S. Thompson was convicted under Utah Code section 76-9-201 for making repeated calls to his ex-wife, Carolyn, after she previously told him not to call back. The trial court found that the defendant telephoned Carolyn late at night eleven times within a one-hour time period. Carolyn told the defendant not to call several times that night, but the defendant continued his calls. As a result, Carolyn finally called the Provo City Police Department, and Officer Michael Bastían was dispatched to Carolyn’s house. While Officer Bastían was at her house, the defendant called again. Officer Bastían answered the line, learned the defendant’s location, and advised the defendant to remain where he was. Officer Bastían then went to Thompson’s apartment, where he found Thompson in an intoxicated state, and cited him for telephone harassment.
¶ 2 At trial, Thompson’s defense was that he had been calling to prevent Carolyn from killing herself, which he claimed she said she would do in a phone call she made to him earlier that night. However, the defendant admitted that he did not raise those concerns with Officer Bastían. Rather, according to Officer Bastían, he explained that he had been calling to find out whether his wife still loved him and because he wanted to see his daughter. The trial court found the defendant guilty of telephone harassment because, in violation of section 76-9-201(l)(b), the defendant had made repeated telephone calls with the intent to annoy Carolyn after she had asked him not to call.
¶ 3 On appeal, defendant challenged his conviction, arguing that section 76-9-201 was unconstitutionally overbroad and void for vagueness in violation of the First Amendment to the United States Constitution and the Utah Constitution.
Provo City v. Thompson,
¶ 4 The court of appeals’ affirmance of defendant’s conviction of telephone harassment under the unwanted calls provision of Utah Code section 76 — 9—201(l)(b) was correct. We also hold that the court of appeals improperly reached the issue of whether the first portion of 76-9-201(l)(b) is facially over-broad.
STANDARD OF REVIEW
¶ 6 Constitutional challenges to statutes present questions of law, which we review for correctness.
Midvale City Corp. v. Haltom,
ANALYSIS
¶ 6 At the time of the incident giving rise to this case, Utah Code section 76-9-201 read as follows:
(1) A person is guilty of telephone harassment and subject to prosecution in the jurisdiction where the telephone call originated or was received if with intent to annoy, alarm another, intimidate, offend, abuse, threaten, harass, or frighten any person at the called number or recklessly creating a risk thereof, the person:
(a) makes a telephone call, whether or not a conversation ensues;
(b) makes repeated telephone calls, whether or not a conversation ensues, or after having been told not to call back, causes the telephone of another to ring repeatedly or continuously;
(c) makes a telephone call and insults, taunts, or challenges the recipient of the telephone call or any person at the called number in a manner likely to provoke a violent or disorderly response;
*738 (d) makes a telephone call and uses any lewd or profane language or suggests any lewd or lascivious act; or
(e) makes a telephone call and threatens to inflict injury, physical harm, or damage to any person or the property of any person.
(2) Telephone harassment is a class B misdemeanor.
Utah Code Ann. § 76-9-201 (1999) (current version at Utah Code Ann. § 76-9-201 (2003)).
¶ 7 At issue here is subsection (l)(b). Defendant’s conviction was sustained under the second portion of subsection (l)(b), which prohibits a person with the requisite intent from making repeated telephone calls after being told not to call. For clarity of reference, we will refer to this portion as the unwanted calls provision. The court of appeals invalidated the first portion of subsection (l)(b), which prohibits a person with the requisite intent from making repeated telephone calls, whether or not a conversation ensues. We designate this portion the repeated call provision. Provo City now asks us to hold that the repeated call provision is not facially overbroad.
I. STANDING
¶ 8 Before we reach the merits of Provo City’s argument, we must first decide whether the constitutional validity of the repeated calls provision was properly before the court of appeals.
See Salt Lake City Corp. v. Prop. Tax Div. of Utah State Tax Comm’n,
A. Basic Standing Requirements
¶ 9 To properly bring an issue before the court for adjudication, a party must have standing. “In essence[,] the question of standing is whether the litigant is entitled to have the court decide the merits of the dispute or of particular issues.”
Warth v. Seldin,
B. Facial Overbreadth as an Exception to Traditional Standing Requirements
¶ 10 When a challenge of statutory overbreadth is made, an exception to the basic standing requirements is available in the First Amendment context. “The First Amendment overbreadth doctrine ... represents a departure from the traditional rule that a person may not challenge a statute on the ground that it might be applied unconstitutionally in circumstances other than those before the court.”
State v. Haig,
¶ 11 The rationale for the facial overbreadth doctrine rests on the very real possibility that an overbroad statute mil cause injury not only when applied to punish protected speech, but also in its “chilling effect” on protected activity. Individuals who are contemplating participating in protected speech may choose to avoid possible prosecution or litigation by refraining from the constitutionally protected activity.
See Provo City Corp. v. Willden,
¶ 12 This exception, however, does not relieve the burden of the challenging party to meet the other requirements for standing. To have standing in the context of a facial overbreadth challenge, “a party must still ‘demonstrate its own cognizable injury in fact.’ ”
Haltom,
¶ 13 As a corollary, “[t]he rule still stands that where defendants were not charged with an activity, the adjudication of that activity, though encompassed under the sanctions of the statute, must await a real controversy.”
Jordan,
¶ 14 We are aware of no case in which a court, in response to a facial overbreadth challenge to a statute, has found invalid a portion inapplicable to the defendant but nonetheless affirmed the defendant’s conviction based on a different, valid portion of the statute. Neither are we aware of any case in which a court employs one of two statutory provisions, both of which proscribe the conduct at issue, to uphold a conviction while the other is declared invalid.
¶ 15 Rather, courts entertain facial overbreadth challenges only where the outcome of the ease rests on the court’s determination of the constitutionality of the applicable portion of the statute.
See Provo City v. Whatcott,
¶ 16 Thus, in
Whatcott,
the court properly applied the facial overbreadth exception to the normal requirements of standing to analyze the two portions of the statute under which the defendant could have been convicted. 2000 UT App at ¶ 9 n. 2,
¶ 17
Jordan
presented a similar situation. There, defendants were convicted under a portion of the statute prohibiting inducing a minor to pose in the nude
for the purpose of sexual arousal. Jordan,
¶ 18 As the cases above illustrate, a defendant may only challenge multiple portions of a statute if invalidating each of the challenged portions would be necessary to find that defendant’s conduct fell outside the statute’s proscriptions. If a finding that one portion is valid will suffice to uphold a conviction, a defendant lacks standing to challenge, and a court cannot properly adjudicate, the constitutionality of another portion of the statute. Essentially, a court may not issue an advisory opinion as to a statutory provision unnecessary to the outcome of the case because it is one that the parties do not have standing to litigate.
II. APPLICATION
¶ 19 In the court of appeals, defendant raised a general facial overbreadth challenge to section 76-9-201 even though the statute was not overly broad as applied to him.
Thompson,
¶ 20 The court of appeals found that the particular provision most applicable to the defendant’s conduct, the unwanted calls provision of 76-9-201(l)(b), was not overbroad because “there is no right to audibly invade another’s home or place of business by telephone ring in an attempt to commandeer her listening ear when she has affirmatively expressed a desire to be left alone.”
Thompson,
¶ 21 Once the court of appeals upheld the unwanted calls provision, it should have held that defendant had no standing to challenge the constitutionality of the repeated calls provision. First, he could not and did not claim
*741
that he had suffered injury as a result of the implementation of the repeated calls provision. Second, and most notably, any injury the defendant could have alleged would not be redressed by a favorable decision: regardless of the court’s decision as to the repeated calls provision, defendant’s conviction would stand under the unwanted calls provision, which the court found to be valid. As a result, the issue of whether the repeated calls provision was valid was no longer properly before the court once it had determined that defendant’s conviction was supported by a different, valid portion of the statute. As in
Jordan,
¶ 22 This lack of meaningful effect to the parties in this case renders the court of appeals’ decision as to the repeated calls provision advisory in nature. We have observed on many occasions that this court is not inclined “to issue mere advisory opinions.”
Miller v. Weaver,
¶ 23 The soundness of this doctrine is illustrated by the strange posture in which the parties, their counsel, and this court find themselves as a result of the court of appeals’ application of the overbreadth exception to standing requirements. After the court of appeals affirmed his conviction, defendant chose not to appeal that ruling. Instead, Provo City has now appealed the invalidation of the repeated calls provision. Defendant also faces an awkward situation. Because he has not appealed his conviction, he is limited to arguing for the invalidation of the repeated calls provision with no real incentive to litigate the issue.
¶ 24 If a defendant declines to litigate an issue under these circumstances, this court cannot benefit from the virtues of an advocate-based system of justice in which each party’s counsel brings all the significant competing arguments to the court’s attention. If defendant instead chooses to litigate the matter, he cannot “reasonably be expected properly to frame the issues and present them with the necessary adversarial zeal,” because the court’s ultimate decision will not affect him.
Haltom,
¶ 25 Because the validity of the repeated calls provision was not properly before the court of appeals, it is not properly before us, and any decision as to the validity of that provision would be advisory. Therefore, we decline to reach the merits of Provo City’s argument.
CONCLUSION
¶26 The court of appeals’ affirmance of defendant’s conviction under the unwanted calls provision, the second portion of Utah Code section 76 — 9—201(l)(b), was correct. Because the parties before the court did not have standing in the court of appeals to litigate the issue of whether the repeated calls provision, the first portion of subsection (l)(b), was constitutionally overbroad, the court of appeals’ determinations as to that portion of subsection (l)(b) were advisory in nature and without precedential value. We therefore vacate that portion of the court of appeals’ decision.
