Luis Alonzo Calixtro v. Markwayne Mullin et al

Luis Alonzo Calixtro filed a federal habeas petition under 28 U.S.C. § 2241 in the Western District of Oklahoma on April 20, 2026, challenging his immigration detention. The respondents include Senator Markwayne Mullin, though the precise basis for naming Mullin has not been detailed in available filings.

The case carries an 'Immigration 2241 Full Consent' notation, meaning Calixtro has consented to have a magistrate judge handle all proceedings, including final disposition.

The docket number is 26-cv-01797, but this entry appears to be a system-level duplicate of at least two other docket entries — cases 16642 and 16643 — carrying the same caption and the same underlying petition. No judge has been assigned. Until the court reconciles the duplicate entries, it is unclear which docket will carry the live proceeding forward.

Section 2241 is the standard vehicle for a detained person to challenge the legality of federal custody. In the immigration context, petitioners typically argue that their detention is prolonged without adequate process, that a removal order is unlawful, or that the government lacks authority to hold them under current statutory or constitutional limits.

The specific grounds Calixtro raises are not yet visible in the public record.

The court issued an order on April 20, 2026 — the same day the petition was filed. The content of that order is not detailed in available information, but same-day orders in habeas cases typically address service on respondents, set a response deadline, or flag procedural defects. No response from the government appears in the record yet.

The duplicate docket problem is the immediate obstacle. If the clerk's office does not consolidate or close the redundant entries, the case risks procedural confusion — competing dockets, missed deadlines, or conflicting orders. That administrative question will resolve before any merits briefing begins.
