NOT FOR PUBLICATION FILED UNITED STATES COURT OF APPEALS JUL 17 2026 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS FOR THE NINTH CIRCUIT
CARSTEN IGOR ROSENOW Ph. D., No. 25-6997 D.C. No. Plaintiff - Appellant, 3:19-cv-01297-WQH-MMP v. MEMORANDUM* META PLATFORMS, INC.; YAHOO INC.,
Defendants - Appellees.
Appeal from the United States District Court for the Southern District of California William Q. Hayes, District Judge, Presiding
Submitted July 15, 2026**
Before: McKEOWN, OWENS, and LEE, Circuit Judges.
Carsten Rosenow filed a pro se action against Facebook and Yahoo for
violations of the Stored Communications Act (SCA), 18 U.S.C. § 2702, and the
Wiretap Act, 18 U.S.C. § 2511, after both companies disclosed his communications
* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). over their platforms to law enforcement. Those disclosures ultimately led to his
convictions for attempted child sexual exploitation and possession of child sexual
abuse material. See United States v. Rosenow, 50 F.4th 715 (9th Cir. 2022)
(affirming Rosenow’s conviction). He now appeals the district court’s dismissal of
his Second Amended Complaint (SAC) without leave to amend, and the denial of
his motion for reconsideration. We have jurisdiction under 28 U.S.C. § 1291, and
we affirm.
We review de novo a district court’s dismissal of a complaint under Federal
Rule of Civil Procedure 12(b)(6), and we accept the factual allegations as true.
Mudpie, Inc. v. Travelers Cas. Ins. Co. of Am., 15 F.4th 885, 889 (9th Cir. 2021).
We review a district court’s denial of a motion for reconsideration for abuse of
discretion. Kona Enters., Inc. v. Est. of Bishop, 229 F.3d 877, 883 (9th Cir. 2000).
1. Dismissal of the SCA claims. The SCA prohibits providers of electronic
communication and remote computing services from “divulg[ing] to any person or
entity the contents” of electronically stored communications, records, and other
information. § 2702(a). The district court correctly dismissed Rosenow’s SCA
claims against Facebook and Yahoo. The companies’ actions were legal under three
exceptions to the SCA’s prohibition: (1) the disclosures were made in connection to
an National Center for Missing and Exploited Children (NCMEC) report; (2)
Rosenow consented to the disclosure of the communications; and (3) the parties
2 25-6997 disclosed the communications to protect their rights and property. Id. § 2702(b)(3),
(5), (6).
First, the disclosures are lawful because they were disclosed “in connection
with a report submitted” “to the [NCMEC]” “under section 2258A.” Id. §
2702(b)(6). Facebook and Yahoo had knowledge of an “apparent” violation of sex
exploitation laws “involv[ing] child pornography” based on Rosenow’s
communications on their platforms, and they disclosed the communications in a
report submitted to the NCMEC. 18 U.S.C. § 2258A(a); Rosenow, 50 F.4th at 738–
39. While Section 2258A(b) provides that a report to the NCMEC “may” include
certain information, the language does not limit the contents to images, as Rosenow
contends. In any case, some of the disclosures did contain images.
Second, the disclosures are lawful under the SCA because Rosenow consented
to his communications being potentially disclosed. § 2702(b)(3). The district court
properly incorporated both Facebook and Yahoo’s terms of service into the
complaint because the SAC “refer[red] extensively” to them. Khoja v. Orexigen
Therapeutics, Inc., 899 F.3d 988, 1002 (9th Cir. 2018) (citation omitted). Those
terms of service that Rosenow agreed to reasonably alerted him to the potential of
3 25-6997 disclosure. See Calhoun v. Google, LLC, 113 F.4th 1141, 1147 (9th Cir. 2024);
Rosenow, 50 F.4th at 732.1
Third, Appellees’ disclosures fall under the SCA’s exception for the
“protection of the [providers’] rights or property.” § 2702(b)(5). Facebook and
Yahoo acted to prevent their services from being used in the production of child
pornography and to comply with legal duties and avoid potential consequences.
Rosenow, 50 F.4th at 733; § 2258A(a), (e) (“When a provider has ‘actual knowledge’
of circumstances supporting a violation, the provider must report such ‘facts or
circumstances’ to NCMEC ‘as soon as reasonably possible,’” or the provider must
pay substantial fines).
Rosenow responds to the application of the above exceptions by arguing that
the district court incorrectly interpreted the SCA and its exceptions. Specifically, he
argues that the district court misapplied the interpretive canon that courts must
1 Rosenow’s attempts to distance himself from the agreements are unavailing. As to Facebook’s policy, Rosenow alleges he “may have” opened the account in Germany, and thus he might have agreed to different terms. We need not accept such conjecture as true at the motion to dismiss stage. See In re Gilead Scis. Sec. Litig., 536 F.3d 1049, 1055 (9th Cir. 2008) (“We are not required to accept as true . . . allegations that are merely conclusory, unwarranted deductions of fact, or unreasonable inferences.”). Rosenow also claims that he never agreed to Yahoo’s U.S. terms of service for the “europe_120@yahoo.com” account because he opened the account in Asia, but plainly contradicts that assertion by alleging that the account was “his Yahoo USA email account.” Regardless, he does not explain how the terms differ such that it would make a difference as to whether he consented.
4 25-6997 interpret the specific over the general because it construed the above exceptions
broadly, thereby overriding other specific provisions in the SCA. This argument is
unavailing because the above exceptions are specific as applied to this context.2
2. Dismissal of the Wiretap Act claim. The district court correctly
dismissed the Wiretap Act claim against Yahoo. The Wiretap Act makes it unlawful
to “intentionally intercept[ ] … any wire, oral, or electronic communication” or to
“use[ ]” or “disclose[ ]” the contents of any intentionally intercepted communication.
18 U.S.C. § 2511(1). “Intercept” under the Wiretap Act has a “narrow definition”—
the communication “must be acquired during transmission, not while it is in
electronic storage.” Konop v. Hawaiian Airlines, Inc.,

2. Dismissal of the Wiretap Act claim. The district court correctly
dismissed the Wiretap Act claim against Yahoo. The Wiretap Act makes it unlawful
to “intentionally intercept[ ] … any wire, oral, or electronic communication” or to
“use[ ]” or “disclose[ ]” the contents of any intentionally intercepted communication.
18 U.S.C. § 2511(1). “Intercept” under the Wiretap Act has a “narrow definition”—
the communication “must be acquired during transmission, not while it is in
electronic storage.” Konop v. Hawaiian Airlines, Inc., 302 F.3d 868, 878 (9th Cir.
2002) (citation omitted). Here, the communications disclosed by Yahoo were stored
communications as opposed to intercepted communications, which are not protected
by the Wiretap Act. Rosenow admitted that Yahoo “pulled his full chat history on the
Yahoo USA Messenger,” and included a “date of last reported chat,” suggesting that
2 Rosenow also fleetingly references a First Amendment argument. We do not address this argument because it was inadequately briefed. Brownfield v. City of Yakima, 612 F.3d 1140, 1149 n.4 (9th Cir. 2010). Even if we did, the First Amendment only applies to government action, and both Facebook and Yahoo acted as private actors here. Rosenow, 50 F.4th at 729-31 (concluding that Facebook and Yahoo were not government actors because “a private actor does not become a government agent simply by complying with a mandatory reporting statute”).
5 25-6997 the communications were previously stored and retrieved thereafter. This admission
rebuts Rosenow’s attempt to pivot and characterize the disclosures as “intercepted.”
3. Denial of motion for reconsideration. As a threshold matter, although
Rosenow explicitly requests reversal of the district court’s denial of his motion for
reconsideration, he does not sufficiently argue why the district court erred and thus
forfeits that challenge. Brownfield, 612 F.3d at 1149 n.4. In any case, it was not an
abuse of discretion for the district court to deny Rosenow’s motion for
reconsideration because he did not make the requisite showing. See Kona Enters.
Inc. v. Estate of Bishop, 229 F.3d 877, 890 (9th Cir. 2000); United States v. Alpine
Land & Reservoir Co., 984 F.2d 1047, 1049 (9th Cir. 1993).3
AFFIRMED.
3 The district court did not abuse its discretion in declining to exercise supplemental jurisdiction over Rosenow’s state law claims. Sanford v. MemberWorks, Inc., 625 F.3d 550, 561 (9th Cir. 2010) (A district court has discretion to decline to exercise supplemental jurisdiction, and the balance of factors (judicial economy, convenience, fairness, and comity) will usually “point toward declining to exercise jurisdiction”) (citation omitted).
