Notice Regarding Impending Government Shutdown

If the federal government enters a lapse in appropriations (aka "a shutdown") on October 1, 2025, the United States District Court and the United States Probation Offices will remain open, and all court operations will continue as scheduled. During Phase 1 of a lapse in of appropriations balances from fees and no-year appropriations allow the judiciary to sustain operations until those fees and appropriations are exhausted. Once those fees and appropriations are exhausted, the judiciary has no available funds to continue operations and enters Phase 2 of a lapse in appropriations. During Phase 2 of a lapse in appropriations the judiciary must reduce operations to perform only excepted activities. The Court will issue further guidance regarding excepted activities should the lapse in appropriations progress into Phase 2.

 

Procedures for Access and Management of Sealed and Restricted Documents

On September 24, 2025, Chief Judge Brimmer entered General Order 2025-2 regarding procedures for access and management of sealed and restricted documents (hereinafter referred to as "sealed documents"). Effective immediately, sealed documents will continue to be filed in CM/ECF under existing procedures but will no longer be accessible or viewable by electronic means. Because sealed documents filed in CM/ECF will no longer be accessible or viewable electronically, service cannot be accomplished through CM/ECF. Instead, parties will have to serve sealed documents by other appropriate means as provided by the Federal Rules of Procedure. The Court (and Probation Office) will serve sealed documents in paper by US mail. A party with the right to access a sealed document in a case who requires a copy of a sealed document must contact the Clerk's Office or Probation Office. Requests for paper copies of sealed documents will be subject to the current docket copy fee rate. For more information and a copy of the General Order please click here.
Any questions about the filing of and access to sealed documents should be directed to the Clerk's Office at 303-844-3433, or the Probation Office at 303-844-5424.
