Appeals from the United States District Court for the Southern District of Florida D.C. Docket No. 9:20-cv-81366-WPD ____________________

Before JORDAN, NEWSOM, and LAGOA, Circuit Judges. PER CURIAM: Robert Walker and Tamiko Peele, Chapter 13 debtors pro- ceeding pro se, appeal the district court’s order affirming the bank- ruptcy court’s orders granting Barry Mittelberg’s motions to allow a late-filed claim and for relief from a stay. Their notices of appeal indicate that they also seek to challenge the district court’s orders granting various filing extensions. After Walker and Peale filed this appeal, the bankruptcy court dismissed their Chapter 13 case. We recently dismissed their separate appeal of the district court’s denial of their motion to re- consider that Chapter 13 case’s dismissal. Walker v. U.S. Bank Nat’l Ass’n, No. 21-13937, 2022 WL 5237915, at *1 (11th Cir. Oct. 6, 2022). We also recently affirmed the district court’s denial of a temporary injunction against their attorneys in the bankruptcy pro- ceeding. In re Walker, No. 21-12114, 2022 WL 4477259, at *1 (11th Cir.

21-10205 Opinion of the Court 3

We now deny as moot 1 Walker and Peale’s appeal of orders related to Mittelberg—Walker’s attorney in a previous personal-in- jury case. As we explained in our earlier decision, we lack jurisdic- tion if a case is moot—for example, because the dismissal of a Chap- ter 13 case makes it impossible to grant the prevailing party any effectual relief. Id. at *1 (citing Neidich v. Salas, 783 F.3d 1215, 1216 (11th Cir. 2015)). We can provide relief on collateral matters, but we can’t change the completed bankruptcy plan. Id. Here, this appeal is moot because the district court order that Walker and Peale challenge relates to Mittelberg’s claim in the bankruptcy plan—it doesn’t concern a collateral matter. To the extent any of the various grievances and requests for relief that Walker and Peele raise on appeal are collateral matters, those ar- guments and requests for relief are outside the scope of this ap- peal. 2 DISMISSED AS MOOT.

1 We review jurisdictional issues de novo and can consider jurisdiction sua sponte. In re Donovan, 532 F.3d 1134, 1136 (11th Cir. 2008). 2 Walker and Peele also move for fees and costs and for judicial notice of re- lated proceedings. We conclude that granting that relief would be inappropri- ate here. Accordingly, we deny those motions as moot.
