Petitioner—Appellee,

Harris County District Attorney’s Office,

Defendant—Appellant. ______________________________

Appeal from the United States District Court for the Southern District of Texas USDC No. 4:09-CV-2999 ______________________________

Before Smith, Southwick, and Ho, Circuit Judges. Jerry E. Smith, Circuit Judge: Carlos Ayestas was convicted of capital murder and sentenced to death. He filed a federal habeas corpus petition raising claims of ineffective assistance of counsel (“IAC”). After his petition was denied, Ayestas filed a Federal Rule of Civil Procedure 59(e) motion to alter the judgment. Shortly thereafter, his habeas counsel located, in the case file provided by the pro- secution, a memorandum indicating that the state had sought the death pen- alty on account of Ayestas’s non-citizen status. Ayestas filed a motion to amend his habeas petition, seeking to add Case: 25-70014 Document: 90-1 Page: 2 Date Filed: 03/09/2026

No. 25-70014

Eighth and Fourteenth Amendment selective-prosecution claims. The dis- trict court dismissed the claims in the motion to amend, holding that they were jurisdictionally barred as a “second or successive habeas corpus appli- cation” under 28 U.S.C. § 2244(b). Six years later, Ayestas filed a Federal Rule of Civil Procedure 60(b) motion to reopen the judgment, citing the intervening decision in Banister v. Davis, 590 U.S. 504 (2020), which held that Rule 59(e) motions are not “suc- cessive habeas corpus applications” under § 2244(b). The district court granted the motion. Ayestas filed an amended habeas petition, and discovery commenced. Over assertions of work-product privilege from the Harris County District Attorney’s Office (“HCDA”), Ayestas sought, and the district court grant- ed, discovery of charging memoranda for comparator capital murder defen- dants within a thirty-year span and the complete file related to Ayestas. HCDA appeals the discovery order. Because we have jurisdiction over the appeal under the collateral- order doctrine and the district court lacked jurisdiction over Ayestas’s selective-prosecution claims, we vacate the discovery order and dismiss the selective-prosecution claims.

I. Santiaga Paneque was found dead in Houston in 1995. Law enforce- ment identified Ayestas and two others as persons of interest. The Harris County District Attorney was John B. Holmes, Jr., and Kelly Siegler was his Court Chief. Before Ayestas was arrested, Siegler wrote, and Holmes signed, an internal Capital Murder Summary (the “Siegler Memorandum”), which recommended that HCDA seek death against Ayestas. The Siegler Memo- randum justified that recommendation with two facts: Paneque was elderly, and “the Defendant is not a citizen.” HCDA ultimately secured a conviction

and death sentence. The Siegler Memorandum was not made available to Ayestas during his state trial because it was treated as confidential work product. Ayestas filed a federal habeas petition challenging his conviction and sentence. Ayestas asserted a constitutional IAC claim. The district court denied his petition on November 18, 2014. 1 Ayestas filed a Rule 59(e) motion to alter the judgment on December 16, 2014, once again asserting IAC. On December 22, 2014, while the Rule 59(e) motion was pending, Ayestas’s counsel discovered the Siegler Memorandum, which HCDA inad- vertently had left in the case file provided to Ayestas’s habeas counsel. On January 9, 2015, Ayestas filed a motion for leave to amend his habeas petition (“2015 Motion to Amend”), arguing that HCDA had sought the death pen- alty against Ayestas on account of his non-citizen status, violating the Eighth and Fourteenth Amendments. The district court denied the 2015 Motion to Amend. The court held that the motion constituted a “second or successive habeas corpus applica- tion” under 28 U.S.C. § 2244(b)(2), which generally bars such applications. Further, the court held that Ayestas’s claims based on the Siegler Memoran- dum did not meet the exceptions listed in § 2244(b)(2)(B) because Ayestas did not “allege that the [Siegler Memorandum] could not have been discov- ered previously though the exercise of due diligence.” Thus, the court held that the claims were jurisdictionally barred. The litigation seemingly came to an end when the Fifth Circuit denied relief on Ayestas’s IAC claim and the Supreme Court denied certiorari. Ayestas v. Davis, 933 F.3d 384 (5th Cir.

_____________________ 1 The district court had denied his petition in 2011, before the Supreme Court granted certiorari and remanded in light of relevant IAC cases decided in 2012 and 2013. See Ayestas v. Thaler, 569 U.S. 1015 (2013).

2019), cert. denied, 589 U.S. 1203 (2020). In 2020, the Supreme Court decided Banister. The Court held that a Rule 59(e) motion to alter or amend a habeas court’s judgment is not a second or successive habeas petition under § 2244(b)(2). Ayestas filed a Rule 60(b) motion for relief from judgment, citing Banister. The district court granted Ayestas’s Rule 60(b) motion. First, it held that Ayestas’s Rule 60(b) attack on the 2015 order refusing amendment was not a successive petition under § 2244(b)(2) because the 2015 order was a “previous ruling which precluded a merits determination.” Second, it held that, under Banister, the 2015 Motion to Amend was not a successive habeas application because it was made in the posture of Rule 59(e). Ayestas filed an amended habeas petition, and discovery commenced. Ayestas served a subpoena on HCDA seeking, in part, case files for relevant Hispanic and non-citizen defendants, along with all charging memoranda for HCDA defendants charged with murder or capital murder from 1979 to 2008. HCDA asserted work-product and deliberative-process privileges. Ayestas filed a motion to compel. The magistrate judge granted the motion ordering HCDA to produce “(i) charging memoranda created from 1979 to 2008 (the ‘Covered Period’) for comparator defendants charged with capital murder who are sufficiently likely to be non-white, foreign nationals, or non-citizens; (ii) charging memo- randa from the Covered Period for comparator defendants charged with cap- ital murder of victims with certain demographic attributes; (iii) full access to the prosecutorial file from the Ayestas prosecution, including any material that the HCDA treats as privileged and confidential.” HCDA did not object to the order in the district court. HCDA appeals.

II. “An appellate federal court must satisfy itself not only of its own jur- isdiction, but also of that of the district court in a cause under review. This court reviews subject-matter jurisdiction de novo as a question of law.” Cadence Bank v. Johnson, 160 F.4th 197, 201 (5th Cir. 2025) (citation modified).
