(In Chambers) Order by Judge Stanley Blumenfeld, Jr.: Petitioner filed a motion for a temporary restraining order (TRO), which, though styled as a motion, fails to comply with the procedural requirements for filing a motion. See, e.g., L.R. 7-3, 7-4. The Court therefore construes the motion as an ex parte application for a temporary restraining order that fails to comply with the procedural and notice requirements in Fed. R. Civ. P. 65, L.R. 65-1, and L.R. 7-19.1. Petitioner shall promptly serve the TRO application on Respondents and file proof of service demonstrating compliance with all applicable rules and orders no later than March 4, 2026. Failure to file proof of service will result in summary denial of the application. THERE IS NO PDF DOCUMENT ASSOCIATED WITH THIS ENTRY. (sod) TEXT ONLY ENTRY (Entered: 03/02/2026)

(In Chambers) Order by Judge Stanley Blumenfeld, Jr.: Petitioner's counsel contacted chambers and filed a request for an emergency stay stating that he believes that Petitioner's transfer is imminent (Dkt. No. 10). On this record, however, such relief appears premature. The government is required to provide Petitioner and his counsel with 48 hours' notice prior to any transfer (Dkt. No. 8), and Petitioner has not provided adequate evidence that the government has violated that order. The government is reminded that violation of the Court's order may result in contempt proceedings and/or other appropriate sanctions. THERE IS NO PDF DOCUMENT ASSOCIATED WITH THIS ENTRY.

(In Chambers) Order by Judge Stanley Blumenfeld, Jr.: By 8:00 a.m. on May 7, 2026, each party shall submit a supplemental brief addressing the following: (1) whether the phrase "pending a decision on whether the alien is to be removed" in 8 U.S.C. § 1226(a) encompasses both (a) the government's pre-initiation decision-making phase and (b) the adjudicative phase before the immigration court, or is limited to one of those phases; (2) whether 8 C.F.R. § 1236.1(b), read together with 8 U.S.C. § 1226(a), imposes a mandatory sequencing requirement that conditions arrest on the prior issuance of a notice to appear (NTA), or instead governs arrest at or after initiation of proceedings without limiting the Government's authority to arrest prior to issuance of an NTA; (3) if § 1236.1 does not impose a mandatory sequencing requirement and the government fails to promptly initiate removal proceedings following an arrest pursuant to a warrant, what authority, if any, does a district court have to order the government to initiate proceedings, release the petitioner, or provide other relief; and (4) if § 1236.1 imposes a mandatory sequencing requirement and the government violates it, whether the government may cure that violation by obtaining and executing a new arrest warrant immediately upon release. In addressing these issues, the parties shall analyze the text, structure, and interaction of all relevant statutes and regulations. THERE IS NO PDF DOCUMENT ASSOCIATED WITH THIS ENTRY.
