v.

STEVEN ANDEREGG, Defendant-Appellee.

Appeal from the United States District Court for the Western District of Wisconsin.

No. 3:24-cr-0050 — James D. Peterson, Chief Judge.

ARGUED OCTOBER 30, 2025 — DECIDED AUGUST 25, 2026

Before LEE, PRYOR, and KOLAR, Circuit Judges. LEE, Circuit Judge. Steven Anderegg is charged with producing , distributing, and possessing visual depictions of minors engaged in sexually explicit conduct and transferring such material to a minor under the age of sixteen. According to the government, Anderegg produced these images using Stable Diffusion, a generative artificial intelligence (“GenAI”) software that allowed him to create hyper-realistic images of prepubescent children engaging in sexually explicit acts.

2 No. 25-1354

When Anderegg moved to dismiss the indictment, the district court granted the motion as to the possession charge and denied the remainder. In doing so, the court held that 18 U.S.C. § 1466A(b)(1) was unconstitutional as applied to Anderegg because, under Stanley v. Georgia, individuals have a First Amendment right to possess obscenity in the privacy of their home. 394 U.S. 557 (1969). Moreover, in the district court’s view, the government’s attempts to justify a prohibition on the possession of virtual child sexual abuse material (“CSAM”) ran headlong into Ashcroft v. Free Speech Coalition, where the Supreme Court rejected substantially identical arguments . 1 535 U.S. 234, 250 (2002). This is despite the Supreme Court’s prior holding in Osborne v. Ohio, which permitted the government to proscribe the in-home possession of

1 Federal criminal law defines “child pornography” as the “visual de-

piction” of a minor “engaging in sexually explicit conduct.” 18 U.S.C. § 2256(8); see also United States v. Williams, 553 U.S. 285, 288 (2008) (child pornography generally “consists of sexually explicit visual portrayals that feature children.”). More recently, the Fourth Circuit has recognized that “the term ‘child sexual abuse material’ more ‘accurately reflects what is depicted—the sexual abuse and exploitation of children.’” United States v. Tucker, 60 F.4th 879, 887 (4th Cir. 2023) (citation modified); see also Child Sexual Abuse Material, U.S. Dep’t of Just. 1 (June 2023), https://www.justice .gov/d9/2023-06/child_sexual_abuse_material_2.pdf [https://perma.cc/E3HM-AX7Q] (Department of Justice explaining that although the term “child pornography” appears in some federal statutes, the term “child sex abuse material” is preferred). Thus, the Fourth Circuit has used “child sexual abuse material” interchangeably with the term “child pornography” to “reflect more accurately the abusive and exploitative nature of [the act].” United States v. Kuehner, 126 F.4th 319, 322 n.1 (4th Cir. 2025). The Second Circuit has followed suit. United States v. Guard, 152 F.4th 375, 381 n.2 (2d Cir. 2025). Following their lead, we also employ the term CSAM where possible.

No. 25-1354 3

CSAM depicting actual children. 495 U.S. 103, 109–11 (1990). The government then filed this interlocutory appeal, challenging the dismissal of the possession charge.

We now live in an age where GenAI models can render images depicting the abuse of virtual children that are virtually indistinguishable from those depicting the abuse of actual children. This case illuminates how this evolving technology complicates the lines drawn by the Supreme Court in Stanley, Osborne, and Free Speech Coalition. Indeed, in Free Speech Coalition , the Supreme Court addressed the scope of First Amendment protections for virtual CSAM, but that was nearly twenty-five years ago, and the image-generation technology available today was likely unimaginable back then. Given the relentless advancement in artificial intelligence models, we have some concerns about the lines these cases draw, but we are not free to redraw them ourselves. See United States v. Rush, 130 F.4th 633, 637, 638 (7th Cir. 2025) (“The rule of law demands we follow binding Supreme Court precedent. … [W]e leave to the Supreme Court the prerogative of overruling its own decisions.”). Because we conclude that Stanley and Free Speech Coalition control Anderegg’s as-applied challenge to § 1466A(b)(1), we must affirm.

I. Background

According to the government, in October 2023, Meta Platforms , Instagram’s parent company, reported the online transmission of potential CSAM to the CyberTipline of the National Center for Missing and Exploited Children (“NCMEC”). See 18 U.S.C. § 2258A. An Instagram user apparently sent a direct message containing what appeared to be AI-generated images depicting CSAM to an account belonging to a minor. According to Meta, at least one image depicted 4 No. 25-1354

“what appeared to be a … prepubescent juvenile male … with his legs spread far apart exposing his erect penis.” Meta also noted that the image appeared to be computer-generated. The corresponding message history showed the account user explaining to the minor how he had created the images by inputting text prompts into Stable Diffusion, a text-to-image GenAI model.

Law enforcement linked the account to Anderegg, whose résumé indicated that he was a software engineer with a background in AI models. Law enforcement then executed a search warrant of his home, his personal laptop, two other cell phones, and other devices.

The government alleges that Anderegg installed Stable Diffusion on his personal laptop and added software components that provided the program with the ability to create depictions of human genitalia. He then used the program to generate photo-realistic images of minors in sexually explicit positions . To produce these images, Anderegg used curated text prompts to generate these images and further refined the output by employing negative prompts to exclude depictions of adults. This process generated hundreds of images depicting nude or semi-clothed prepubescent minors displaying or touching their genitals. Other images, according to the government , portrayed prepubescent minors touching adult male penises or engaging in sexual intercourse. 2 Anderegg was charged with (1) “knowingly produc[ing]” and (2) “knowingly distribut[ing]” visual depictions of

charged do not depict an actual child, nor can they be linked to an actual child. Oral Argument at 21:43.

minors engaged in sexually explicit conduct as well as (3) “knowingly transferr[ing]” such material to a minor under the age of sixteen in violation of 18 U.S.C. § 1466A(a)(1), (d)(1). He was also charged in Count 4 with “knowingly possess [ing] at least one visual depiction that depicted a minor engaging in sexually explicit conduct and was obscene, and any depiction involved in the offense had been shipped and transported in interstate and foreign commerce” in violation of 18 U.S.C. § 1466A(b)(1), (d)(4).

Anderegg filed a flurry of motions, including a motion to dismiss Count 4. As to that count, he argued that being convicted of possessing CSAM would violate his First Amendment rights as recognized by Stanley. The district court agreed and dismissed the possession charge but left the remaining counts intact. The government appeals.
