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.”
