Martinez Santoyo v. Boyden

130 F.4th 784 (9th Cir. 2025) · United States Court of Appeals for the Ninth Circuit · March 11, 2025 · No. 24-1967

Summary

This Ninth Circuit opinion addresses whether the "lapse of time" provision in the U.S.-Mexico extradition treaty incorporates the Sixth Amendment's Speedy Trial Clause. The court held that the treaty language refers exclusively to statutes of limitations and does not mandate application of constitutional speedy trial protections to extradition proceedings. Affirming the district court's denial of a habeas corpus petition, the panel concluded that evaluating such claims would exceed the limited scope of judicial review in extradition cases and improperly require scrutiny of foreign sovereign actions.

  2. Whether the delay between Mexico's arrest warrant and its formal extradition request required denial of extradition under the treaty.

Holdings

  1. The United States-Mexico extradition treaty's 'lapse of time' language does not incorporate the Sixth Amendment Speedy Trial Clause or the Barker v. Wingo balancing test.

Key quotations

In sum, we join the Sixth and Eleventh Circuits in Martinez and Yapp and hold that the extradition treaty's “lapse of time” language does not incorporate the Sixth Amendment Speedy Trial Clause. (12-13)
Rather, they are “designed only to trigger the start of criminal proceedings against an accused; guilt remains to be determined in the courts of the demanding country.” (6)
Foreign states requesting extradition are not required to litigate their criminal cases in American courts. (9)

Factual background

A Mexican judge issued a January 2014 arrest warrant alleging that Santoyo shot a man twice in the head after a heated argument. Mexico provisionally sought his arrest in November 2018, and the United States arrested him on May 12, 2022; he was released on bail on November 4, 2022. Mexico formally requested extradition in July 2022, and the request included the arrest warrant, eyewitness statements, a police report, and an autopsy report. The extradition magistrate certified extradition on February 24, 2023.

Procedural history

Mexico sought Santoyo's extradition to face an aggravated intentional homicide charge. After a magistrate judge certified extradition on February 24, 2023, Santoyo petitioned for habeas relief, arguing that the lapse-of-time provision in the United States-Mexico extradition treaty incorporated the Sixth Amendment Speedy Trial Clause. A magistrate judge recommended rejecting the argument, the district court adopted that recommendation and denied the petition, and the Ninth Circuit affirmed.
