Back Before the Fifth Circuit: DOJ Appeals Another FCPA Acquittal

On May 8, 2026, the U.S. Department of Justice appealed Judge Kenneth Hoyt’s post-verdict acquittal in the FCPA prosecution of Ramón Alexandro Rovirosa Martínez, setting up what could become a significant Fifth Circuit decision on both double jeopardy and the use of translated foreign language evidence in federal criminal trials.

Although a Houston jury convicted Rovirosa in December 2025 on conspiracy and substantive FCPA charges tied to alleged bribery of officials at Mexico’s state-owned oil company, Pemex, Judge Hoyt later vacated the convictions, concluding that the Government’s reliance on certified English translations of Spanish language communications violated the Sixth Amendment’s Confrontation Clause because the translators themselves did not testify.

The appeal raises potentially consequential questions about whether post-verdict acquittals can be reviewed without violating double jeopardy protections, and whether certified translations of foreign language communications are “testimonial” statements requiring live confrontation. This blog post explores those issues and places the appeal in the broader context of the Fifth Circuit’s continuing scrutiny of major FCPA decisions.

Ninth Circuit Vacates Insider Trading Conviction Over Court’s Failure to Investigate Juror Bias

On April 21, 2026, a Ninth Circuit panel vacated an insider trading conviction in United States v. Bolandian, holding that the trial court failed to properly investigate a juror who admitted he was “not sure” he could remain impartial. The case involved a Los Angeles trader accused of profiting from confidential merger tips, resulting in a conviction and 24-month sentence. But on appeal, the court found plain error in allowing the uncertain juror—who ultimately served as foreperson—to remain without further inquiry. Emphasizing the court’s independent duty to ensure juror impartiality, the decision underscores that even without a defense objection, unresolved bias concerns can mandate a new trial—offering both a cautionary note and a safeguard for defense counsel.
