2 summary judgment for the federal government, holding that th e Plaintiffs lacked standing. We **AFFIRM**

. I. Federal law regulates the making of firearms. See 26 U.S.C. §§ 5821

– 22. Since 1968, silencers (also known as suppressors) have been considered “firearms” subject to these regulations. 26 U.S.C. § 5845; Gun Control Act of 1968, Pub. L. No. 90

- 618, § 102, 82 Stat. 1213, 1214. A silencer is a device that at taches to the muzzle of a firearm and makes the firearm quieter when discharged. See 18 U.S.C. § 921(a)(25). As applied to individuals wishing to make a silencer for personal, non

commercial use, federal law imposes the following requirements. First, the individual must pay a $200 excise tax, 26 U.S.C. § 5821, and file a written application for permission to make a silencer with the Bureau of Alcohol, Tobacco, Firearms and Explosives, 26 U.S.C. § 5822. Then, if the application is approved, the individual m ay make the silencer but must register it in the National Firearms Registration and Transfer Record and mark it with a serial number. 27 C.F.R. § 479.64; 26 U.S.C. §§ 5841

– 42. If the application is denied, the individual may not make a silencer, and the $2 00 tax payment is refunded. 27 C.F.R. § 479.64. Making a silencer in violation of these procedures is a crime punishable by a maximum fine of $10,000, imprisonment for up to ten years, or both. 26 U.S.C. § 5871. In 2021, Texas enacted a law providing that “[a] firearm suppressor that is manufactured in [Texas] and remains in [Texas] is not subject to federal law or federal regulation.” **Tex. Gov’t Code Ann.** § 2.052(a). The law also requires that upon “written notification to the attorney general [of Texas] b y a United States citizen who resides in [Texas] of the citizen’s intent to manufacture a firearm suppressor . . . the attorney general [of Texas] shall seek a declaratory judgment from a federal district court in [Texas] that Case: 23-10802 Document: 60-1 Page: 2 Date Filed: 06/21/2024No. 23

- 10802

3 [the Texas statute] is consis tent with the United States Constitution.” Id. § 2.054. On February 23, 2022, David Schnitz, Tracy Martin, and Floice Allen (the “Individual Plaintiffs”) provided such “written notification” to Texas Attorney General Ken Paxton of their intent to manufact ure a firearm suppressor. The next day, Paxton and the Individual Plaintiffs (collectively, the “Plaintiffs”) filed suit seeking (1) “a declaratory judgment that neither the Commerce Clause nor the Necessary and Proper Clause authorize federal regulation o f the making of a firearm suppressor for personal use in Texas,” and (2) injunctive relief against “federal law as applied to taxing and regulating firearm suppressors made in Texas for personal use in Texas because that law violates the Second Amendment.” The Plaintiffs later dropped their request for a declaratory judgment, proceeding only on their claims for injunctive relief against the application, tax, registration, and serial

- number requirements on Second

- Amendment grounds. The parties cross

- moved fo r summary judgment. The federal government’s motion argued that the Plaintiffs lacked standing, that the court lacked jurisdiction because of the Tax Anti

- Injunction Act, and that the Plaintiffs’ claims failed on the merits. The district court concluded th at neither the Individual Plaintiffs nor Texas had standing to pursue their claims and therefore granted summary judgment in favor of the federal government on that basis. 1

4 II.
We review the district court’s standing determination de novo

. Chavez v. Plan Benefit Servs., Inc. , 77 F.4th 370, 378 (5th Cir. 2023)

. III. We begin with the Individual Plaintiffs

. To have Article III standing, the Individual Plaintiffs “must have (1) suffered an injury in fact, (2) that is fairly traceable to the challenged conduct of the defendant, and (3) that is likely to be redressed by a favorable judicial decision.” Spokeo, Inc. v. Robins , 578 U.S. 330, 338 (2016). On appeal, as before the district court, the parties primarily contest whether the Individual Plaintiffs demonstr ated an injury in fact. “To establish injury in fact, a plaintiff must show that he or she suffered ‘an invasion of a legally protected interest’ that is ‘concrete and particularized’ and ‘actual or imminent, not conjectural or hypothetical.’” Id. at 339 ( quoting Lujan v. Defs. of Wildlife , 504 U.S. 555, 560 (1992)). Where, as here, a plaintiff raises a pre

- enforcement challenge to a federal statute, the injury

- in

- fact requirement is satisfied where the plaintiff shows a serious “intention to engage in a co urse of conduct arguably affected with a constitutional interest, but proscribed by a statute, and there exists a credible threat of prosecution thereunder.” Susan B. Anthony List v. Driehaus , 573 U.S. 149, 159 (2014) (quoting Babbitt v. United Farm Worker s Nat’l Union , 442 U.S. 289, 298 (1979)); see also, e.g. , Zimmerman v. City of Austin , 881 F.3d 378, 389 (5th Cir. 2018) (requiring a “serious intention to engage in conduct proscribed by law”). 2

2 The Individual Plaintiffs have not raised

— and have therefore forfeited

— other potential bases for standing beyond pre
- enforcement standing vis

- à

- vis the criminal penalties imposed by the federal regulatory scheme at issue. See Ctr. for Bio logical Diversity Case: 23-10802 Document: 60-1 Page: 4 Date Filed: 06/21/2024No. 23

- 10802

5 The Individual Plaintiffs claim that they have established injury in fact through their signed, unsworn declarations, each of which stated, in relevant part: I intend to personally manufacture a firearm suppressor for my
own non
- commercial, personal use. The firearm suppressor will be manufactured in my home from basic materials without the inclusion of any part imported from another state other than a generic and insignificant part, such as a spring, screw, nut, or pin. For two reasons, we find that these declarations are insufficient to “establish a serious intention to engage in conduct proscribed by law.” Zimmerman , 881 F.3d at 389

. A. First, the declarations do not state any intention to engage in conduct proscribed by law . Rather, the declarations state only that the Individual Plaintiffs “intend to personally manufacture a firearm suppressor for [their]

own non
- commercial, personal us e.” But, as the federal government points out, the statutes at issue do not prohibit the Individual Plaintiffs from making a firearm suppressor. Rather, they only prohibit making a firearm suppressor without complying with the applicable procedures and req uirements , i.e. , applying for approval, paying the requisite tax, registering the suppressor, and labeling it with a serial number. See 26 U.S.C. § 5871. This is a distinction with an important difference because it differentiates this case from those in w hich the statutory scheme at issue is a blanket prohibition.

6 Take, for example, National Rifle Association of America, Inc. v. McCraw , a case concerning a pre

- enforcement challenge to a Texas criminal statute prohibiting individuals under the age of 21 fr om carrying handguns in public. 719 F.3d 338, 342 (5th Cir. 2013). The district court had found that the plaintiff’s declared intent to “carry a handgun outside of the home” was insufficient to establish standing, in part because the criminal provision at issue allowed an individual to carry a handgun in public if the individual had a concealed

- carry license, and the plaintiff had not specifically alleged any “desire to carry a handgun . . . without a license.” Jennings v. McCraw , No. 5:10

- cv
- 141

- C, 2012 WL 12898407, at * 2

– 3 (N.D. Tex. Jan. 19, 2012). We reversed, explaining that because Texas’s licensing program prohibited granting concealed

- carry licenses to individuals under 21, “[t]he criminal provision forb[ade] [the plaintiff] from carrying a handgun a ltogether.” McCraw , 719 F.3d at 345. For this reason, the intent to carry a handgun outside of the home generally was sufficient to bring the plaintiff’s intended conduct within the ambit of the criminal prohibition. Here, the opposite is true. The Indivi dual Plaintiffs have only stated an intent “to personally manufacture a firearm suppressor” but say nothing about whether they intend to personally manufacture a firearm suppressor without applying for government approval , and they make no claim that they are statutorily ineligible for such approval. So, they have failed to show that their intended conduct is within the scope of what 26 U.S.C. § 5871 prohibits and therefore lack standing to bring their pre

- enforcement challenge. In this sense, the Individu al Plaintiffs’ declared intent is more akin to that which was deemed insufficient in Zimmerman . In that case, an Austin City Councilmember challenged a campaign

- finance law that placed an aggregate limit on the amount of monetary contributions that could b e accepted from persons outside of the Austin area. Zimmerman , 881 F.3d at 382. The plaintiff had submitted a declaration stating that, absent the Case: 23-10802 Document: 60-1 Page: 6 Date Filed: 06/21/2024No. 23

- 10802

7 challenged law, he would have solicited funds from individuals outside of the Austin area. Id. at 389. But, a s we pointed out, the law at issue did “not preclude solicitations ; it preclude[d] only accepting aggregate contributions over the relevant limit.” Id. (cleaned up) (emphases added). So, “[s]tating [a] desire to solicit funds . . . d[id] not establish an i ntent to accept funds above the proscribed limit,” and the plaintiff therefore lacked standing. Id. Here, the challenged statute does not preclude making a silencer; it precludes only making a silencer without submitting to various government

- imposed requi rements. So, stating a blanket desire to make a silencer does not establish an “intention to engage in conduct proscribed by law.” Id. at 389.
B. Second, the declarations lack the necessary detail to establish that the Individual Plaintiffs’ professed inte nt to make a silencer is sufficiently “serious” to render their feared injury “imminent” rather than merely speculative or hypothetical. As the Supreme Court explained in Lujan , at the summary
- judgment stage, declarants’ profession of “‘some day’ intention s [to engage in certain conduct]

— without any description of concrete plans, or indeed even any specification of when the some day will be

— do not support a finding of the ‘actual or imminent’ injury” required for standing. 504 U.S. at 564. To determine whet her the Individual Plaintiffs’ professed intent to make silencers is sufficiently serious, it is helpful to look specifically at cases concerning pre

- enforcement Second

- Amendment claims. Again McCraw

— and its companion case, National Rifle Association of A merica, Inc. v. Bureau of Alcohol, Tobacco, Firearms, and Explosives , 700 F.3d 185, 188 (5th Cir. 2012) (hereinafter, “ BATFE ”), challenging a federal law prohibiting the sale of handguns to individuals under the age of 21

— are instructive. In both cases, th e same individual plaintiff

— Andrew Payne

— submitted a detailed declaration describing his passion for the safe handling Case: 23-10802 Document: 60-1 Page: 7 Date Filed: 06/21/2024No. 23

- 10802

8 of firearms and explaining how and when he would engage in the proscribed conduct if the challenged laws did not exist. With respect to t he federal law prohibiting the sale of handguns to individuals under 21, Payne explained, “I identified a handgun that I wanted to purchase

— a new Taurus .357 magnum that was selling for just under $500” at a local firearms dealer

— and he declared, under pen alty of perjury, that “[i]f [the retailer] could legally sell me this handgun, I would buy it (or one very similar to it) from that store now.” Decl. of Andrew Payne at 3, BATFE , 700 F.3d 185 (No. 11

- 10959 ), ECF No. 25 at 56. Similarly, in the case challen ging the state law prohibiting him from carrying a handgun in public, Payne’s declaration was unequivocal: “If Texas law did not prohibit me from doing so, I would carry a handgun outside of the home”

— specifically, his “father’s handgun when patronizing [a local] Wal

- Mart” in an area of town where Payne felt unsafe. Decl. of Andrew Payne at 2, McCraw , 719 F.3d 338 (No. 12

- 10091 ), ECF No. 17 at 59. We therefore had no hesitation holding that Payne had a serious intention to engage in the conduct that he clai med would expose him to criminal liability. BATFE , 700 F.3d at 191

– 92; McCraw , 719 F.3d at 345.
Out

- of

- circuit case law is in accord. In Antonyuk v. Chiumento , the Second Circuit found that a plaintiff had established a serious intention to violate a criminal law banning the carriage of firearms in “sensitive locations,” including public zoos, based on the plaintiff’s “aver[ments] in his declaration that he and his wife frequently visit the [local] Zoo . . . so that [they] can see the otters and wolves , . . . that they would visit the zoo . . . at least once[] within the next 90 days” and that “he intend[s] to carry [his] firearm when [they] visit.” 89 F.4th 271, 333, 352 (2d Cir. 2023) (internal quotation marks omitted). Similarly, in Montana Shooting Sports Association v. Holder , the Ninth Circuit found that an individual had a serious intention to violate federal laws criminalizing the manufacturing of firearms and ammunition without a government

- issued license where the plaintiff had Case: 23-10802 Document: 60-1 Page: 8 Date Filed: 06/21/2024No. 23

- 10802

9 “not merely alle ged a vague desire to manufacture and sell unlicensed firearms if he [won his] lawsuit, but ha[d] made specific allegations substantiating [that] claim,” including that he “ha[d] a background in running his own shooting range equipment manufacturing busine ss, ha[d] identified . . . the component parts of the [firearm he wanted to make], ha[d] design plans for the firearm ready to load into manufacturing equipment, and ha[d] identified hundreds of customers who ha[d] ordered the [firearm] at his asking price .” 727 F.3d 975, 978

– 80 (9th Cir. 2013). 3 The detailed allegations and declarations that were sufficient for standing in BATFE , McCraw , Antonyuk , and Montana Shooting stand i n stark contrast to those submitted in this case. For example, in Montana Shootin g , the plaintiff presented design plans for the firearm he intended to make and identified each of the parts necessary to complete the manufacturing process. And in BATFE , the plaintiff identified the specific handgun that he intended to purchase. Here, th e Individual Plaintiffs have provided no information concerning the specific type of silencer that they allegedly intend to make or what parts they will use to make it. Moreover, and perhaps most importantly, each of the plaintiffs in BATFE , McCraw , Antony uk , and Montana Shooting expressed an unequivocal intent to engage in the proscribed conduct immediately if the challenged restrictions did not exist, whereas here, the Individual Plaintiffs have expressed only a vague intention to make a silencer
at some indeterminate point in the future. The Individual Plaintiffs’ professed “some day intentions” to make a silencer, without any concrete

**_____________________**
3 Montana Shooting went to the Ninth Circuit at the motion

- dismiss stage, 727 F.3d at 979, so the court needed only look at the allegations in the complaint to evaluate standing. More

— namely, “ affidavit or other evidence ”

— is required here. Lujan , 504 U.S. at 561

10 details concerning the type of silencer they will make or even when they will make it, is insufficient to establish injur y in fact. See Lujan , 504 U.S. at 564. 4 To be sure, there are limits to the degree of specificity a plaintiff can be expected to provide in a declaration. And, as the Second Circuit recognized, courts must be “mindful that a plaintiff may fall between st ools: allege future conduct too imminent and the claim will become moot, but allege a generic or distant intention and the injury will be insufficiently specific.” Antonyuk , 89 F.4th at 371. But the bottom line is that “it is simply not all that hard” to w rite a declaration with enough detail to establish a serious intention to engage in a course of conduct. See i d. The Individual Plaintiffs have fallen well short of that mark here.

4 To be clear, our holding does not require the Individual Plaintiffs to c ommit a crime to have standing. To the contrary, it is well established that “where threatened action by government is concerned, we do not require a plaintiff to expose himself to liability before bringing suit to challenge the basis for the threat.” MedI mmune, Inc. v. Genentech, Inc. , 549 U.S. 118, 128

– 29 (2007) (emphasis removed)

. The Individual Plaintiffs would face no risk of criminal liability by identifying the materials they plan to use to make a silencer in a declaration, and they need not collect those parts if it would be illegal to possess them without a permit.

11 approved) or prohibiting (when the application is not approved) Texa ns’ ability to use firearm suppressors for the purpose of home defense

. ” We hold that Texas has not establish ed a valid quasi

- sovereign interest because it has not shown that the challenged statutes implicate the State’s own interests in addition to and “apart from the interests of particular private parties.” Alfred L. Snapp & Son, Inc. v. Puerto Rico ex rel. Barez , 458 U.S. 592, 607 (1982). Snapp itself is illustrative of what a s tate must show to satisfy this requirement. There, Puerto Rico, as part of its participation in a federal jobs program, had recruited over two thousand Puerto Rican farmworkers to be sent to harvest apples for private growers on the east coast. Id. at 597. But when the workers arrived, the growers refused to employ them on the basis that Puerto Rican farmhands were inferior and unproductive. Id. The Supreme Court found that Puerto Rico had parens patriae standing on an economic

- wellbeing basis because the c onduct at issue concerned efforts to stigmatize the entire Puerto Rican labor force and therefore implicated the economic interests of Puerto Rico itself beyond the interests of the specific individuals who lost job opportunities. Id. at 609

– 10.
Contrast P uerto Rico’s showing in Snapp with that of Louisiana in Harrison v. Jefferson Parish School Board , 78 F.4th 765 (5th Cir. 2023). There, Louisiana claimed parens patriae standing to challenge a local school board’s disciplinary policy based on its “ quasi

- so vereign interest in preventing its political subdivisions [ i.e. , the school board] from violating the constitutional rights of 52,000 public schoolchildren .” Id. at 772. As we explained, this was not a valid quasi

- sovereign interest because Louisiana was n ot claiming “injury to its citizens health or economic well

- being in a way that also implicates its own interests ”; rather, “Louisiana’s asserted interest [was] wholly derivative of the interests of [the individual] students,” who were perfectly capable of suing the school board themselves. Id . at 773 (emphasis added); see also Pennsylvania v. Kleppe , 533 F.2d 668, 675 (D.C. Cir. 1976) Case: 23-10802 Document: 60-1 Page: 11 Date Filed: 06/21/2024No. 23

- 10802

12 (finding lack of quasi

- sovereign interest in light of “the presence . . . of a more appropriate party or parties capable of bringing the suit ”). Applying these principles here, it is plain that Texas’s asserted quasi

sovereign interest is wholly derivative of the personal Second

- Amendment interests of its citizens and therefore not a valid quasi

- sovereign interest at all. See Harrison , 78 F.4th at 773. As the district court succinctly put it:

“ Texas may not merely litigate as a volunteer the personal claims of its citizens. And it is hard to think of a more personal interest than one’s ability to better hear a home intruder in the middle of the night and fend them off with the aid of a home

- made silencer. ” 5
B.
Texas claims that it “ also has standing to vindicate its sovereign interest in the power to create and enforce a legal code .” True, s uch a sovereign interest exists. See Snapp , 458 U.S. at 601. But it is not implicated here. Specifically, Texas asserts that the challenged federal statutes interfere with its ability to enforce Section 2.052 of the Texas Government Code, which provides that “[a] firearm suppress or that is manufactured in [Texas] and remains in [Texas] is not subject to federal law or federal

**_____________________**
5 Because Texas has failed to establish an injury to its quasi

- sovereign interest s and “[p]rinciples of judicial restraint dictate that if resolution of an issue effectively dispo ses of a case, we should resolve the case on that basis without reaching any other issues that might be presented,” Manning v. Upjohn Co. , 862 F.2d 545, 547 (5th Cir. 1989), we do not address Texas’s argument that it would have standing to bring a claim ba sed on an injury to its quasi

- sovereign interests against the federal government despite the so

- called Mellon bar , which prohibits states from bringing parens patriae suits against the federal government

. See Massachusetts v. Mellon , 262 U.S. 447, 486 (192 3) (explaining that when it comes to a state’s citizens’ “ relations with the federal government ,” “ it is the United States, and not the state, which represents them as parens patriae ”).

13 regulation .” **Tex. Gov’t Code Ann.** § 2.052(a) . But as we have previously explained, “[a] state has standing based on a conflict between federal and state law if the state statute at issue regulates behavior or provides for the administration of a state program, but not if it simply purports to immunize state citizens from federal law .” Texas v. Nuclear Regul. Comm ’ n , 78 F.4th 827, 836 (5th Cir. 2023) (quoting T exas v. United States , 787 F.3d 733, 749 (5th Cir. 2015) ) (emphasis added). Section 2.052 falls squarely into the latter category.
The black

- letter rule set forth in Texas v. Nuclear Regulatory Commission and Texas v. United States is derived from the Fou rth Circuit’s decision in Virginia ex rel. Cuccinelli v. Sebelius

— a case with facts remarkably similar to this one. See Texas v. United States , 787 F.3d at 749 ( quoting Virginia ex rel. Cuccinelli v. Sebelius , 656 F.3d 253, 269 (4th Cir. 2011) ). In Cuccine lli , the Commonwealth of Virginia filed suit challenging the “individual mandate” provision of the Affordable Care Act. 656 F.3d at 266. As its basis for standing, Virginia argued that it had a sovereign interest in creating and enforcing its legal code, n amely the V irginia Health Care Freedom Act (“VHCFA”), which provided, in relevant part, that “no resident of this Commonwealth

. . . shall be required to obtain or maintain a policy of individual insurance coverage.” Id. at 267

– 68. As the Fourth Circuit rightly explained: “ the VHCFA regulates nothing and provides for the administration of no state program. Instead, it simply purports t o immunize Virginia citizens from federal law. In doing so, the VHCFA reflects no exercise of ‘ sovereign power, ’ for Virginia lacks the sovereign authority to nullify federal law. ” Id. at 270. Rather, what Virginia was really trying to do was “escape [the Mellon ] bar merely by codifying its objection to the federal statute in question .” Id. The Fourth Circuit refused to permit such an end

around, which would have improperly “ convert [ed] the federal judiciary into

a ‘ forum ’ for the vindication of a state ’ s ‘ generalized grievances about the Case: 23-10802 Document: 60-1 Page: 13 Date Filed: 06/21/2024No. 23

- 10802

14 conduct of government. ’ ” Id. (quoting Flast v. Cohen , 392 U.S. 83, 106 (1968) )

. Like Virginia, Texas cannot avoid the Mellon bar by legislative fiat. Section 2.052 merely purports to immunize Texas citizens making silencers in Texas from federal firearms law. It therefore reflects no exercise of Texas’s sovereign power and provides no standing for Texas to challenge the federal laws with which Section 2.052 conflicts. See Nuclear Regul. Comm ’ n , 78 F.4th at 836.
