Pursuant to Civil Local Rules 6-1(b), 6-2, and 7-12, the undersigned Parties by and through their
counsel of record hereby declare, stipulate, and respectfully request:
1. 	By stipulation of the Parties and Order of the Court (ECF 2811), the deadline for Parties to
file updated witness lists, which will include whether a witness is a “will call” or “may call,” and time
estimates for each witness, was set for April 6, 2026.
2. 	The Parties have diligently worked on and met and conferred regarding their updated witness
lists, but require a modest enlargement of time to file their respective lists.
3. 	The Parties have not previously requested an extension to this deadline in the Court’s Order
Regarding Pretrial Schedule (Breathitt) (ECF 2811).
4. 	The Parties do not believe that the time modification sought will otherwise have any effect
on the schedule for the case, including any other deadlines set forth in prior orders.
5. 	The Parties have met and conferred and agree, subject to Court approval, to enlarge the time
to file their updated witness lists by four (4) days to April 10, 2026.
