HabeasCivil Procedure
In one sentence

In Yu v. Warden, Judge Swain transferred the action to the Southern District of Texas because Peng Yu was detained there.

Who this affects

Peng Yu, whose detention challenge was transferred from the Southern District of New York to the Southern District of Texas; the Warden was the respondent.

What happened

Peng Yu challenged his current detention by filing a letter in the Southern District of New York. The Clerk’s Office treated the letter as a petition under a federal law allowing people in custody to challenge the legality of their detention. Yu also requested arrest warrants for three Texas judges.

The court explained that a detention challenge generally belongs in the federal district where the person is confined because that court has authority over the custodian. Yu was detained at the Brazos County Jail in the Southern District of Texas, so the New York court transferred the action there in the interest of justice.

Judge Laura Taylor Swain ordered the Clerk to transfer the action, said that no order requiring an answer would issue from the New York court, and closed the action there. The court also said that no certificate allowing an appeal would issue and denied permission to appeal without paying fees.

Case
Yu v. Warden · No. 1:25-cv-06084
Judge
Laura Swain
Date
July 24, 2025

Background

Peng Yu, who was detained at Brazos County Jail in College Station, Texas, challenged his current detention and stated that he was falsely imprisoned. He initiated the action by filing a letter. The Clerk’s Office treated the letter as a petition for a writ of habeas corpus under 28 U.S.C. § 2241, a federal procedure for a person in custody to challenge the legality of that custody. Yu also requested arrest warrants for three Texas judges, whom the opinion says presumably had some role in his current criminal proceedings.

Court’s reasoning

The court explained that a person may use a Section 2241 petition to challenge the constitutionality of pretrial detention. For such a petition, the court must have jurisdiction—legal authority over—the custodian. The court stated that jurisdiction over a challenge to physical confinement generally lies in the federal district where the person is confined.

Yu was detained at Brazos County Jail, which is in the Southern District of Texas. Relying on 28 U.S.C. § 1406(a), the court concluded that transferring the action to that district was in the interest of justice. The opinion does not decide whether Yu’s detention was lawful.

Disposition

The court directed the Clerk of Court to transfer the action to the United States District Court for the Southern District of Texas. It stated that no order requiring an answer would issue from the Southern District of New York and that the action was closed in that court.

The court also determined that the petition did not make a substantial showing that a constitutional right had been denied, so it said a certificate of appealability would not issue. It certified that an appeal would not be taken in good faith and denied permission to appeal without paying the required fees. The opinion does not state whether the Southern District of Texas accepted or later acted on the transferred case.
