In Miguel Diaz v. United States, Judge Liman denied Diaz’s post-conviction challenge without prejudice because his direct appeal was still pending.
Miguel Diaz’s challenge to his federal conviction was denied without prejudice because his direct appeal was still pending; the court did not decide his Second Amendment claim.
What happened
In Miguel Diaz v. United States, Miguel Diaz filed a self-represented petition challenging his federal conviction for possessing ammunition after being convicted of a felony. He argued that the conviction violated the Second Amendment.
The court treated Diaz’s petition under the law used to challenge a federal conviction or sentence, rather than the law used to challenge how a sentence is carried out. Because Diaz’s direct appeal was still pending, the court found the petition premature and did not decide his Second Amendment argument.
Judge Lewis J. Liman denied the petition without prejudice as prematurely filed, allowing Diaz to file a later challenge after the appeals court issues its mandate. The court also declined to issue a certificate allowing an appeal and denied permission to proceed without paying fees for an appeal.

Background
Miguel Diaz, who was incarcerated at USP Canaan in Waymart, Pennsylvania, filed a self-represented petition under 28 U.S.C. § 2241. He challenged his April 11, 2025 federal conviction under 18 U.S.C. § 922(g)(1), asserting that the conviction violated the Second Amendment. The petition was originally filed in the Eastern District of Pennsylvania and was transferred to the Southern District of New York.
Diaz had pleaded guilty to one count of being a felon in possession of ammunition. The court sentenced him to 112 months in prison followed by three years of supervised release. Diaz had filed a direct appeal in the United States Court of Appeals for the Second Circuit, and that appeal remained pending when the district court considered this petition.
Court’s Analysis
The court explained that Section 2255 is the usual procedure for a federal prisoner challenging the constitutionality of a federal conviction or sentence. Section 2241 generally concerns the execution of a sentence, such as sentence calculations, prison discipline, transfers, or prison conditions. Because Diaz had already been sentenced and was challenging his conviction, the court construed his Section 2241 petition as a motion under Section 2255.
The court stated that a criminal defendant generally must pursue a direct appeal before filing a Section 2255 motion. Although a district court may sometimes consider a Section 2255 motion while a direct appeal is pending, the court declined to do so here. It reasoned that addressing the same issues while the appeal was pending could create confusion, waste judicial resources, or result in a decision affected by the appeal. The court did not reach the merits of Diaz’s Second Amendment argument.
Disposition
The court denied the petition for a writ of habeas corpus, as construed under 28 U.S.C. § 2255, without prejudice as prematurely filed. The order specified that this did not prevent Diaz from filing a Section 2255 motion after the Second Circuit issues its mandate in his direct appeal. The court stated that the denial would not trigger the restriction on a later “second or successive” Section 2255 motion concerning the conviction or sentence.
The court terminated all pending matters and directed the Clerk of Court to enter judgment. It also determined that the petition did not make a substantial showing of a denial of a constitutional right, so a certificate of appealability would not issue. The court further certified that an appeal would not be taken in good faith and denied permission to proceed without paying fees for purposes of an appeal.
