Oct 21 2024Petition GRANTED. The petition for a writ of certiorari in No. 23-1068 is granted. The cases are consolidated, and a total of one hour is allotted for oral argument. Justice Alito took no part in the consideration or decision of these petitions. VIDED.
Oct 21 2024Because the Court has consolidated these cases for briefing and oral argument, future filings and activity in the cases will now be reflected on the docket of No. 23-1067. Subsequent filings in these cases must therefore be submitted through the electronic filing system in No. 23-1067. Each document submitted in connection with one or more of these cases must include on its cover the case number and caption for each case in which the filing is intended to be submitted. Where a filing is submitted in fewer than all of the cases, the docket entry will reflect the case number(s) in which the filing is submitted; a document filed in all of the consolidated cases will be noted as “VIDED.”
Oct 28 2024Motion for an extension of time to file the briefs on the merits filed. VIDED.

The time to file the joint appendix and petitioners' briefs on the merits is extended to and including December 13, 2024.
