1 2 3 4 5 UNITED STATES DISTRICT COURT 6 SOUTHERN DISTRICT OF CALIFORNIA 7 8 “LILY,” “SARAH,” and “PIA,” Case No.: 23-cv-00644-WQH-DEB

9 ORDER Plaintiffs, 10 v. 11 CARSTEN IGOR ROSENOW, 12 a/k/a CARLOS SENTA, 13 Defendant. 14 15 16 HAYES, Judge: 17 The matter before the Court is the pending Motion to Amend the Pleadings and the 18 Case Schedule filed by Plaintiffs “Lily,” “Sarah,” and “Pia.” (ECF No. 127.) 19 I. BACKGROUND 20 On March 26, 2026, the Court issued an Order partially granting the Motion for 21 Summary Judgment (ECF No. 75) filed by Plaintiffs “Lily,” “Sarah,” and “Pia.” (ECF No. 22 124.) The Court granted summary judgment for Plaintiffs on the “identity” and “sexually 23 explicit conduct” elements of their claims under 18 U.S.C. § 2255. Id. at 35. The Court 24 denied summary judgment as to the “possession” element. Id. 25 The parties each filed Pretrial Disclosures pursuant to Federal Rule of Civil 26 Procedure 26(a)(3) on April 27 and April 28, 2026, respectively. (ECF Nos. 125, 126.) 27 On April 29, 2026, Plaintiffs filed the pending Motion to Amend the Pleadings and 28 the Case Schedule (“Motion to Amend”). (ECF No. 127.) Plaintiffs seek leave to amend 1 (1) the pleadings “to reflect that [Plaintiff] Pia is no longer a minor” and (2) the “Case 2 Schedule to give the parties sufficient time to establish that the thumb drives in Defendant’s 3 possession contained Plaintiffs’ CSAM files.” Id. at 3. 4 On May 6, 2026, Defendant Carsten Igor Rosenow (“Defendant”) filed an 5 Opposition to the Motion to Amend. (ECF No. 128.) 6 II. AMENDING THE PLEADINGS 7 Plaintiffs seek to amend the pleadings to substitute Plaintiff “Pia” as a plaintiff in her 8 own right. Plaintiffs state that “Pia” has “attained the age of majority” and thus no longer 9 requires a “next friend” to represent her interests in this action because she is now “legally 10 able to act on her own behalf.” (ECF No. 127 at 3–4.) 11 On July 8, 2025, Plaintiffs filed the Second Amended Complaint (“SAC”), the 12 operative pleading. (ECF No. 66.) The SAC amended the pleadings by, among other things, 13 substituting “Pia” as a Plaintiff in her own right for the next friend that previously 14 represented her interests. Id.; see also ECF No. 19. Because the operative pleading already 15 reflects that “Pia” is no longer a minor and is representing her own interests in this action, 16 the Court denies the Motion to Amend (ECF No. 127) as moot to the extent it seeks to 17 amend the pleadings. 18 III. AMENDING THE CASE SCHEDULE 19 Plaintiffs seek to amend the case schedule to allow more time “for Plaintiffs to 20 arrange to present the images that the Defendant possessed and to present the testimony of 21 law enforcement agents who seized and analyzed the media containing the images of 22 Plaintiffs from Defendant’s home.” (ECF No. 127 at 3.) 23 A. Contentions 24 Plaintiffs contend that “significant logistical hurdles” exist that justify amending the 25 case schedule to allow Plaintiffs to file an additional dispositive motion. Id. at 5. Plaintiffs 26 contend that they need more time “to present the required evidence to the Court to prove 27 that Defendant possessed Plaintiffs’ CSAM images” because “the images are contraband,” 28 so Plaintiffs must “arrange for the transportation and identification of the images by law 1 enforcement officers.” Id. at 3, 5. Specifically, Plaintiffs state that they have communicated 2 with the United States Attorneys’ Office in the Southern District of California and the 3 Federal Bureau of Investigation, seeking to “secur[e] testimony by declaration, as well as 4 in person, from the necessary federal agents.” Id. at 5. Plaintiffs state that the government 5 has acknowledged their request pursuant to United States ex rel. Touhy v. Ragen, 340 U.S. 6 462 (1951), but has not provided a timeline for its response. Id. Plaintiffs further state that 7 “at least one or more of the law enforcement agents previously involved in the criminal trial 8 now live and work outside of the Southern District of California.” Id. 9 Plaintiffs state that they plan to file another Motion for Partial Summary Judgment in 10 this action. Id. at 4. They contend that, if the Court grants summary judgment for Plaintiffs 11 on the possession issue, the Court would “avoid the necessity of a trial of this matter and 12 the attendant summoning from distant locations of []federal agents to testify, taking them 13 away from immediate law enforcement duties, and also avoid the transporting of Defendant 14 from his current location in Seagoville, Texas to the Southern District of California.” Id. 15 In response, Defendant contends that Plaintiffs were not diligent in seeking evidence 16 of possession because “[t]he need for forensic proof and law-enforcement testimony linking 17 [thumb drives] QSD15 and QSD16 to Plaintiffs’ images was known from the outset of this 18 case”; Plaintiffs “were on notice” of the Northern District of California’s ruling in “Amy” 19 v. Curtis, No. 19-cv-02184-PJH, 2021 WL 1391463 (N.D. Cal. Apr. 13, 2021); “Plaintiffs’ 20 logistical difficulties with contraband images and [Touhy] requests to the government . . . 21 were entirely foreseeable”; and Plaintiffs have failed to provide a “concrete showing that 22 the requested extension will actually yield admissible evidence.” (ECF No. 128 at 3–5.) 23 Defendant further contends that successive motions for summary judgment are improper, 24 and that amending the scheduling order would prejudice him due to the “logistical burdens” 25 of litigating a case while incarcerated. Id. at 5–7. 26 B. Discussion 27 Federal Rule of Civil Procedure 16(b)(4) provides that “[a] schedule may be 28 modified only for good cause and with the judge’s consent.” Fed. R. Civ. P. 16(b)(4). “Rule 1 16(b)’s ‘good cause’ standard primarily considers the diligence of the party seeking 2 amendment. The district court may modify the pretrial schedule ‘if it cannot reasonably be 3 met despite the diligence of the party seeking the extension.’” Johnson v. Mammoth 4 Recreations, Inc., 975 F.2d 604, 609 (9th Cir. 1992) (citing Fed. R. Civ. P. 16 advisory 5 committee’s notes to 1983 amendment). “Although the existence or degree of prejudice to 6 the party opposing modification might supply additional reasons to deny a motion, the 7 focus of the inquiry is upon the moving party’s reasons for seeking modification. If that 8 party was not diligent, the inquiry should end.” Id. (citation omitted). 9 Federal Rule of Civil Procedure 56 provides that, unless “the court orders otherwise, 10 a party may file a motion for summary judgment at any time until 30 days after the close of 11 all discovery.” Fed. R. Civ. P. 56(b). “Nothing in Rule 56 prohibits successive motions” for 12 summary judgment. Martinez v. High, 91 F.4th 1022, 1027 (9th Cir. 2024). “[A] successive 13 motion for summary judgment is particularly appropriate on an expanded factual record” 14 and “fosters the ‘just, speedy, and inexpensive’ resolution of suits.” Hoffman v. 15 Tonnemacher, 593 F.3d 908, 911 (9th Cir. 2010) (quoting Fed. R. Civ. P.
