February 25, 2026 Filing 29 RESPONSE to #26 MOTION to Dismiss filed by Plaintiff Waldo Mackey. (sgrim)
February 24, 2026 Opinion or Order Filing 28 ORDER by Magistrate Judge Susan Prose on 2/24/2026. This court notes sua sponte that Defendants move to dismiss this case for lack of subject matter jurisdiction. Pursuant to Fed. R. Civ. P. 16(b)(2), this court finds good cause to delay issuing a scheduling order until after the motion is resolved. See Sandoval v. United States, No. 11-cv-01533-REB-KLM, 2011 WL 3682768, at *2 (D. Colo. Aug. 23, 2011) ("Questions of jurisdiction should be resolved at the earliest stages of litigation, so as to conserve the time and resources of the Court and the parties. Thus, a stay of discovery during the pendency of a dispositive motion asserting a jurisdictional challenge may be appropriate and efficient."). Accordingly, if the motion to dismiss is denied at least in part, the parties shall email # [email protected] within three business days to set the scheduling conference. Objections to this order are due within fourteen days. Fed. R. Civ. P. 72(a). For all non-e-filer pro se parties, a copy of this document has been sent via U.S. Mail to the mailing address of record.
