Plaintiffs-Appellants J. Bronson, G. Cook, and D. Cook (“plaintiffs”) subscribe to the religious doctrine of polygamy. G. Cook is married to D. Cook. G. Cook and J. Bronson filed an application for a marriage license, and Defendant-Appellee Sherrie Swensen (“Swensen”), the Clerk for Salt Lake County, Utah, refused to issue the marriage license. Plaintiffs subsequently brought a civil rights action under 42 U.S.C. § 1983, alleging that Swen-sen’s refusal to issue the marriage license violated their associational, substantive due process, and free exercise rights under the First and Fourteenth Amendments to the United States Constitution.
The district court held that plaintiffs possessed standing to challenge the constitutionality of Utah’s civil and criminal prohibitions against the practice of polygamy, as reflected in Utah Code Ann. § 76-7-101, § 3 of the Utah Enabling Act, and § 1 of Article III of the Utah Constitution. Reaching the merits of plaintiffs’ claims, the district court applied controlling Supreme Court and Tenth Circuit precedent and found the absence of a constitutional violation. Consequently, the district court granted summary judgment to Swensen on all of plaintiffs’ claims.
*1102 We exercise jurisdiction pursuant to 28 U.S.C. § 1291. After concluding that plaintiffs have forfeited any challenge to the constitutionality of Utah’s civil prohibition of polygamous marriages, we hold that plaintiffs lack standing to bring claims against Swensen based upon the purported unconstitutionality of Utah’s criminal prohibition of polygamy. We therefore VACATE the district court’s judgment in favor of Swensen on the merits of these criminal-prohibition claims and REMAND the case for entry of an order dismissing these claims for lack of subject matter jurisdiction.
I. BACKGROUND
A. Legislative Background
In 1894, Congress passed the Utah Enabling Act, which demanded as a condition of statehood that Utah enact an “irrevocable” ordinance preserving the security of religious beliefs, but forever prohibiting “polygamous or plural marriages.” See Act of July 16, 1894, ch. 138, § 3, 28 Stat. 107, 108 (“That perfect toleration of religious sentiment shall be secured, and that no inhabitant of said State shall ever be molested in person or property on account of his or her mode of religious worship: Provided, That polygamous or plural marriages are forever prohibited.” (emphasis in original)). Utah complied with this requirement, and, in 1895, a nearly identical version of this proscription was included in Article III of Utah’s Constitution:
The following ordinance shall be irrevocable without the consent of the United States and the people of this State: First:- — -Perfect toleration of religious sentiment is guaranteed. No inhabitant of this State shall ever be molested in person or property on account of his or her mode of religious worship; but polygamous or plural marriages are forever prohibited.
Utah Const, art. Ill, § 1.
The constitutional prohibition of “polygamous or plural marriages” has spawned civil and criminal legislation.
See State v. Holm,
(1) A person is guilty of bigamy when, knowing he has a husband or wife or knowing the other person has a husband or wife, the person purports to marry another person or cohabits with another person.
(2) Bigamy is a felony of the third degree.
(3)It shall be a defense to bigamy that the accused reasonably believed he and the other person were legally eligible to remarry.
Utah Code Ann. § 76-7-101. 2
The Supreme Court of Utah has interpreted the term “marry” in § 76-7-101 as relating to both “legally recognized marriages and those that are non state-sanctioned.”
Holm,
With respect to civil legislation, § 30-1-2 of the Utah Code declares “void” and “prohibited” any marriage involving a person with a “husband or wife living, from whom the person marrying has not been divorced.” Utah Code Ann. § 30-1-2. A county clerk is barred from issuing a marriage license for a “prohibited” marriage. Id. § 30-1-16. In fact, Utah makes it a crime for a clerk or deputy clerk to “knowingly issue a license for any prohibited marriage.” Id. § 30-1-16. An offender is subject to “confinement in the state prison for a term not exceeding two years” and/or to a “fine in any sum not exceeding $1,000.” Id. No marriage may be solemnized without a license issued by the county clerk. Id. § 30-1-7.
B. Factual Background
Plaintiffs subscribe to the religious doctrine of plural marriages, which they define as a “man having more than one wife,” similar to that practiced by the Church of Jesus Christ of Latter-Day Saints in Utah prior to 1890. App. at 19, 33, 46-47. 3
Plaintiffs, G. Cook and J. Bronson, applied for a marriage license and paid the $50.00 filing fee to a deputy clerk at the Marriage Division of the Salt Lake County Clerk’s Office in Salt Lake City, Utah. The application indicated that G. Cook was already married to D. Cook. In addition, G. Cook orally informed two deputy clerks that he desired to legally marry a second wife and that D. Cook consented to this marriage. Swensen, the elected Clerk of Salt Lake County, instructed the two deputy clerks to deny the application and to inform plaintiffs that plural marriage in Utah is illegal. The Clerk’s Office refunded the $50.00 filing fee.
C. Procedural Background
Plaintiffs filed suit under 42 U.S.C. § 1983 against Swensen and the two deputy clerks, alleging that they violated plaintiffs’ federal constitutional rights, including their rights to the free exercise of religion, to intimate expression and association, and to privacy. Plaintiffs sought nominal damages, a declaratory judgment, and injunc-tive relief.
Subsequently, the parties agreed to seek the dismissal of the two deputy clerks. They also stipulated that Swensen acted under color of state law in denying the application. Plaintiffs moved for summary judgment. And, in response, Swensen filed a cross-motion for summary judgment.
After officially dismissing the deputy clerks from the action, the district court entered summary judgment in favor of Swensen. The district court determined that plaintiffs had standing to challenge the constitutionality of § 1 of Article III of the Utah Constitution, § 3 of the Utah Enabling Act, and § 76-7-101. The district court then applied controlling Supreme Court precedent,
Reynolds v. United States,
Plaintiffs filed a motion asking the district court to reconsider its decision. The district court denied that motion. And plaintiffs filed a timely noticé of appeal.
II. DISCUSSION
Plaintiffs appeal the district court’s grant of summary judgment to Swensen on their § 1983 claims, arguing that the district court erred in failing to find the existence of a constitutional violation. We hold that plaintiffs have forfeited their claims contesting the constitutionality of Utah’s civil prohibition of polygamy. We further hold that plaintiffs lack standing to pursue their claims against Swensen based upon the alleged unconstitutionality of Utah’s criminal prohibition of polygamy.
A. Scope of the Appeal
An appellant’s opening brief must identify “appellant’s contentions and the reasons for them, with citations to the authorities and parts of the record on which the appellant relies.” Fed. RApp. P. 28(a)(9)(a). Consistent with this requirement, we routinely have declined to consider arguments that are not raised, or are inadequately presented, in an appellant’s opening brief.
See Exum v. United States Olympic Comm.,
We conclude that plaintiffs’ opening brief
does not
adequately raise and pursue an argument as to the unconstitutionality of Utah’s civil prohibition of polygamous marriages. For instance, plaintiffs’ statement of issues on appeal, while referencing § 3 of the Utah Enabling Act and § 1 of Article III of the Utah Constitution, does not expressly seek to invalidate Utah’s civil statutes prohibiting polygamous marriages.
See Anderson,
Furthermore, plaintiffs’ opening brief does not attempt to explain why Utah’s refusal to give civil recognition to polygamous marriages should be held to contravene their constitutional rights. Instead, plaintiffs’ opening brief is dedicated entirely to establishing the invalidity of Utah’s criminal prohibition of polygamy — that is, to “seeking] an end to the
criminalization
*1105
of the practice of religious polygamy,” regardless of whether “no legal marital rights are afforded to a second or third spouse.”
5
Aplt. Br. at 10 (emphasis added). Plaintiffs do state in two places that they also challenge the validity of Swen-sen’s refusal to grant a marriage license, based upon the unconstitutionality of Utah’s civil prohibition of polygamy.
See id.
at 16, 40 n. 21. But these cursory statements, without supporting analysis and case law, fail to constitute the kind of briefing that is necessary to avoid application of the forfeiture doctrine.
See Adler v. Wal-Mart Stores, Inc.,
In essence, plaintiffs’ opening brief simply attempts to use Swensen’s denial of a marriage license as a vehicle to challenge the constitutionality of Utah’s criminal prohibition of polygamy. We therefore conclude that plaintiffs have forfeited any argument that Utah’s refusal to give civil recognition to polygamous marriages is unconstitutional. 6
B. Constitutionality of Utah’s Criminal Prohibition of Polygamy
Plaintiffs’ substantive challenge to Utah’s criminal prohibition of polygamy faces a litany of seemingly insurmountable precedential obstacles. Case law upholding the criminalization of polygamy from constitutional attack dates back at least to 1878, when in
Reynolds v. United States,
Similarly, constitutional challenges to Utah’s criminal statute outlawing polygamy, Utah Code § 76-7-101, have failed.
*1106
In
Potter,
this Court relied upon
Reynolds
in rejecting attacks that were premised upon the Due Process and Free Exercise Clauses of the United States Constitution.
See Potter,
Despite this wealth of controlling and persuasive precedent, we conclude that the district court lacked subject matter jurisdiction to resolve plaintiffs’ claims against Swensen based upon Utah’s criminal prohibition of polygamy. We hold that these claims — the only claims at issue in this appeal — fail to present a justiciable “case” or “controversy” within the meaning of Article III of the United States Constitution.
1. Standard For Constitutional Standing
This Court reviews
de novo
a district court’s decision as to standing.
See Aid for Women v. Foulston,
(1) it has suffered an “injury in fact” that is (a) concrete and particularized and (b) actual or imminent, not conjectural or hypothetical; (2) the injury is fairly traceable to the challenged action of the defendant; and (3) it is likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.
Friends of the Earth, Inc. v. Laidlaw Envtl. Servs., Inc.,
Each plaintiff must have standing to seek each form of relief in each claim.
See DaimlerChrysler Corp. v. Cuno,
— U.S. -•,
2. District Court’s Analysis
Without distinguishing between Utah’s criminal prohibition of polygamy and its civil prohibition of polygamy, the district court concluded that plaintiffs had standing. Its analysis was predicated upon three points: (1) that plaintiffs’ injury was not the threat of imminent prosecution, but, instead, the “denial of the legal right to practice polygamy,” App. at 282-83; (2) that a causal nexus existed between this injury-in-fact and Swensen’s denial of a marriage license in reliance upon Utah’s prohibition of polygamy; and (3) that a favorable opinion would redress plaintiffs’ injury, as the contested provisions would *1107 be held unconstitutional and the marriage license would issue. For the reasons detailed below, we conclude that the district court erred with respect to the criminal-prohibition claims.
3. Plaintiffs’ Standing to Challenge Utah’s Criminal Prohibition of Polygamy
We hold that plaintiffs have failed to meet their burden of demonstrating constitutional standing to seek prospective or retrospective relief based upon the alleged unconstitutionality of Utah’s criminal prohibition of polygamy.
a. Prospective Relief
On appeal, plaintiffs press for prospective relief in the form of a declaratory judgment that,
inter alia,
the challenged criminal enactments-particularly, the provisions of § 76-7-101 — are unconstitutional. Plaintiffs’ complaint also requests an injunction prohibiting the future enforcement of the criminal enactments. Under the facts of this case, both forms of prospective relief trigger the same standing analysis.
See Tandy,
i. Injury-in-Fact
Plaintiffs argue on appeal that they possess standing to challenge Utah’s criminal prohibition of polygamy due to their
“fear
of criminal prosecution,” including the stigma of being branded as a lawbreaker. Aplt. Br. at 14 (emphasis in original);
see
Aplt. Reply Br. at 2-3. A plaintiff challenging the “validity of a criminal statute under which he has not been prosecuted ... must show a ‘real and immediate threat’ of his future prosecution under that statute to satisfy the injury in fact requirement.”
D.L.S. v. Utah,
This requirement also has been characterized as a “credible” threat of prosecution, one that arises from an “objectively justified fear of real consequences.”
D.L.S.,
As suggested by this standard, a plaintiff need not risk actual prosecution before challenging an allegedly unconstitutional criminal statute.
See, e.g., Ward v. Utah,
The “credible threat” test begs further inquiry into what constitutes the requisite degree of likelihood of enforcement to confer standing to bring a particular claim.
See Seegars v. Gonzales,
At the “credible threat” pole lies pre-enforcement claims brought after the entity responsible for enforcing the challenged statute actually threatens a particular plaintiff with arrest or even prosecution.
See Steffel v. Thompson,
These claims can be juxtaposed with those situated at the “no credible threat” end of the spectrum. There, the affirmative assurances of non-prosecution from a governmental actor responsible for enforcing the challenged statute prevents a “threat” of prosecution from maturing into a “credible” one, even when the plaintiff previously has been arrested under the statute.
See Mink v. Suthers,
In addition, the credibility of a “threat” is diluted when a factual dissimilarity exists between the plaintiffs intended future conduct and the conduct that triggered any prior prosecutions under the challenged statute.
See D.L.S.,
Plaintiffs’ § 1983 claims for prospective relief based upon Utah’s criminal prohibition of polygamy lie closer to the “no credible threat” end of the injury-in-fact continuum. Plaintiffs were never charged, prosecuted, or directly threatened with prosecution under § 76-7-101. Moreover, the alleged credibility of plaintiffs’ fear is contradicted by their repeated admission that “Utah’s criminal law against polygamy is not being enforced.” Aplt. Br. at 48 n.30;
see id.
at 49 n. 34. It is further belied by the policy statement of the Utah Attorney General’s Office that it has “decided to focus law enforcement efforts on crimes within the polygamous communities that involve child abuse, domestic violence and fraud, rather than enforcing § 76-7-101 against consensual polygamous relationships involving adults.”

The Primer: Helping Victims of Domestic Violence and Child Abuse in Polygamous Communities
at 3 (June 2006),
available at
http://www.attygen.state.ut.us/ polygamy/The_Primer.pdf. Plaintiffs also failed to allege or demonstrate that Swen-sen (even if she had the power to do so) is likely to enforce Utah’s criminal laws against plaintiffs in the future.
See Rasmussen,
Plaintiffs rely upon two recent state prosecutions under §
76-7-101
— Green and
Holm
— to justify the objective reasonableness of their fear. However, the defendants in these prosecutions had committed
independent
crimes in connection with forming, their respective polygamous relationships.
See Holm,
ii. Causation
Even if plaintiffs’ fear was based upon a credible threat of prosecution, such that they are suffering a jurisdictionally-cogni-zable injury, they could not satisfy the second requirement of standing — causation. The principle of causation for constitutional standing requires a plaintiffs injury to be “fairly traceable to the challenged
action of the defendant,
and not the result of the independent action of some third party not before the court.”
Nova Health Sys. v. Gandy,
It is well-established that when a plaintiff brings a pre-enforcement challenge to the constitutionality of a particular statutory provision, the causation element of standing requires the named defendants to possess authority to enforce the complained-of provision.
See, e.g., Socialist Workers Party v. Leahy,
For instance, in
Gandy,
we held that the plaintiff, an abortion provider, lacked standing to pursue a pre-enforcement challenge for prospective relief based upon the alleged unconstitutionality of an Oklahoma statute imposing civil liability on abortion providers for performing abortions on minors without parental consent.
Under this precedent, we hold that plaintiffs’ fear of prosecution under § 76-7-101 — the injury that allegedly anchors plaintiffs’ challenge to Utah’s criminal prohibition of polygamy — is not “fairly traceable” to Swensen’s acts. Plaintiffs concede that Swensen has no power to initiate a criminal prosecution. And they have not shown that Swensen has any responsibility for enforcing § 76-7-101. Cf. Utah Const, art. VIII, § 16 (public prosecutors have “primary” authority for prosecution of criminal actions); Utah Code Ann. § 10-3-928 (authorizing city attorney to prosecute certain crimes). As such, there is no nexus between this defendant’s past or possible future conduct and plaintiffs’ fear of criminal prosecution under Utah law.
In the face of this logic, plaintiffs argue that Swensen’s power to grant a marriage license generates the necessary causation for standing. In essence, plaintiffs contend that if Swensen were “to issue a *1111 marriage license and a marriage ceremony was performed,” Aplt. Reply Br. at 5, they would be insulated from criminal prosecution under § 76-7-101 and, consequently, would be free from fear of such prosecution.
We reject this argument. Plaintiffs’ theory of causation is based upon the alleged benefits that would flow to them as a consequence of Swensen’s issuance of a marriage license — not an alleged injury that Swensen’s actions have inflicted or, in imminent fashion, will inflict upon them. 9 Moreover, these benefits (insofar as they could be said to be anything more than speculative) would be the collateral products of Swensen’s exercise of her civil authority. They would not flow from Swensen’s enforcement of Utah’s criminal prohibition of polygamy. Swensen has no authority to enforce that prohibition.
Plaintiffs’ theory, therefore, fails to establish a meaningful nexus between Swen-sen’s actions and the challenged criminal provisions, such that plaintiffs’ alleged harm (ie., fear of criminal prosecution) could be deemed to be fairly traceable to her actions. Furthermore, even if Swen-sen issued a marriage license, this license would not eliminate the possibility (albeit remote) of prosecution: the marriage license would be deemed invalid pursuant to § 30-1-2; and plaintiffs would remain within the technical ambit of § 76-7-101. 10
In sum, plaintiffs cannot establish causation for purposes of Article III standing.
iii. Redressability
Lastly, even if plaintiffs were able to survive the standing analysis as to the first two requirements, they would fail on the last and third requirement of standing — redressability. Standing requires a likelihood that the injury-in-fact will be redressed by a favorable decision.
See Bennett v. Spear,
The absence of a nexus between Swensen’s enforcement powers and the challenged criminal provisions renders ineffectual plaintiffs’ requested prospective relief. Enjoining
this defendant
from enforcing § 76-7-101 would be a meaningless gesture. It would not protect plaintiffs from any threat of future criminal prosecution for polygamous behavior; such prosecutions are the province of governmental actors other than Swensen.
See Okpalobi
b. Retrospective Relief
Plaintiffs’ complaint also seeks retrospective relief — -nominal monetary damages and a declaratory judgment — for Swensen’s allegedly unconstitutional conduct. 11 Again, we find that plaintiffs lack standing to pursue such relief under a theory premised upon the unconstitutionality of Utah’s criminal prohibition of polygamy.
Although plaintiffs repeatedly cast their injury-in-fact in prospective-relief terms, as the credible “threat” of prosecution, they also argue, without much elaboration, that “Swensen’s acts in compliance with the challenged provisions caused harm to plaintiffs.” Aplt. Br. at 17. This eoncluso-ry statement hardly amounts to a clear expression of why plaintiffs have standing to pursue retrospective relief. As best we can discern it, plaintiffs appear to be asserting the following theory: Swensen’s denial of G. Cook’s and J. Bronson’s application for a marriage license, coupled with the psychological and financial consequences attendant to this denial, grants them standing to sue Swensen for monetary damages and declaratory relief based upon her unconstitutional application of the challenged criminal provisions.
This theory of standing cannot withstand scrutiny. We assume arguendo that the first requirement of Article • III standing is satisfied — viz., the denial of a marriage license to enter into a polygamous relationship constitutes a constitutionally cognizable injury. However, plaintiffs still cannot establish the second and third elements: their injury was not caused by Swensen’s application of the challenged criminal provisions and the injury is not “fairly traceable” to this defendant’s application of the challenged criminal provisions.
We start with the causation requirement. Swensen’s statutory obligation to deny plaintiffs’ marriage application was governed by Title 30 of the Utah Code, and, in particular, by § 30-1-2(1) and *1113 § 30-1-16, not by the challenged criminal provisions. See Utah Stat Ann. §§ 17-20-4, 30-1-2, 30-1-16. Nothing in Title 30 authorized Swensen to deny marriage licenses based upon conduct that she believed may violate a particular criminal provision — viz., nothing in Title 30 authorized Swensen to apply, even indirectly, the challenged criminal provisions in denying marriage licenses. Nor have plaintiffs identified a source granting a county clerk such discretion.
And, for related reasons, plaintiffs also cannot satisfy the third standing requirement — redressability. Because the challenged
cñminal
provisions were not the predicate for Swensen’s denial of a marriage license to plaintiffs, affording plaintiffs a retrospective remedy centered on a legal determination that those provisions are unconstitutional would not provide plaintiffs effective relief. It would not redress their claimed harm.
Cf. New York Civil Serv. Comm’n v. Snead,
III. CONCLUSION
We hold that plaintiffs lack standing to challenge the constitutionality of Utah’s criminal prohibition of polygamy. And, on appeal, plaintiffs have forfeited any challenge to the constitutionality of Utah’s civil prohibition of polygamy. Accordingly, we VACATE the district court’s judgment in favor of Swensen on the merits of plaintiffs’ criminal-prohibition claims and REMAND the case for entry of an order dismissing these claims for lack of subject matter jurisdiction.
Notes
. Although this opinion uses the terms interchangeably, a conceptual difference exists between "bigamy” and "polygamy.” "Bigamy” is defined as "the act of marrying one person while legally married to another.” See Black's Law Dictionary 172 (8th ed.2004). "Polygamy,” on the other hand, includes and exceeds the scope of bigamous behavior; it is defined as "the state or practice of having more than one spouse simultaneously.” Id. at 1197.
. Utah enacted a child bigamy statute in 2003. See Utah Code Ann. § 76-7-101.5. Under this statute, it is a second degree felony for a person, knowing he or she has a wife or husband, to marry or to cohabit with a person under the age of eighteen. Id.
. On October 6, 1890, the Church of Jesus Christ of Latter Day Saints officially abolished polygamy as an institutional church practice.
See Oliverson v. West Valley City,
. In mounting their attack on Utah’s criminal prohibition of polygamy, plaintiffs purport to seek the invalidation of § 3 of the Utah Enabling Act and § 1 of Article III of the Utah Constitution. Standing alone, however, these provisions do not establish a criminal regulatory regime. By their terms, they do not establish crimes nor do they impose criminal penalties. Rather, they have provided the foundation for both civil and criminal legislative enactments that prohibit polygamy. Plaintiffs’ singular attack on Utah’s criminal prohibition of polygamy is therefore properly viewed as an effort to invalidate on constitutional grounds Utah’s criminal statute that bars polygamy among consenting adults — that is, § 76-7-101.
. Plaintiffs’ “Summary of Argument” refers only to the absence of a legally-adequate justification for "criminalizing polygamy.” Aplt. Br. at 11. Each topic heading argues solely for the invalidation of Utah’s criminal prohibition of polygamy, specifically referring in most instances to § 76-7-101, which plaintiffs describe as Utah's “anti-bigamy law" or "anti-polygamy law.” And most significantly, the content of plaintiffs’ argument section exclusively analyzes the unconstitutionality of § 76-7-101.
. In their reply brief, plaintiffs protest the idea that they have forfeited any argument concerning the alleged unconstitutionality of Utah's civil proscriptions regarding polygamy. However, plaintiffs do not identify where in their opening brief they mounted a challenge to these provisions. Indeed, plaintiffs' reply brief underscores the exclusive criminal-law focus of their appellate challenge, stating: "This action seeks a judicial determination as to the unconstitutionality of provisions of Utah law and federal law that make, criminal the religious practice of polygamy.” Aplt. Reply Br. at 1 (emphasis added).
. By purporting to enter into a polygamous marriage, J. Bronson and G. Cook would violate § 76-7-101.
See Holm,
. The Utah Attorney General recently made to the Utah Supreme Court a representation of prosecutorial selectivity similar to the one found in
The Primer. See Holm,
. We note that in their complaint plaintiffs did not even request the form of relief upon which they build their theory of causation — in other words, they did not seek injunctive relief that would require Swensen to issue them a marriage license.
. Plaintiffs allude to the possibility that Swensen's refusal to issue a marriage license has
enhanced
the likelihood of their criminal prosecution under § 76-1-101.
See
Aplt. Reply Br. at 4 (“While Ms. Swensen has no power to initiate a criminal prosecution, her actions
directly lead to
or would prevent criminal prosecutions.” (emphasis added)). We summarily reject this theory. Plaintiffs have failed to cite any evidence in the record to suggest that the denial of a marriage license carries any influence on the decision to
prosecute
a defendant under § 76-7-101.
See Lujan,
. In
Rasmussen,
we noted: "While a declaratory judgment is generally prospective relief, in some situations, it has been recognized as retrospective.... Thus, we consider declaratory relief retrospective to the extent that it is intertwined with a claim for monetary damages that requires us to declare whether a past constitutional violation occurred.”
