Jose Ventura-Reyes applied for protection under the Convention Against Torture (CAT). He feared torture in the Dominican Republic because: (1) a politically influential Dominican family believed that he was responsible for the murder of their patriarch in the Dominican Republic; and (2) he was an informant for the U.S. Drug Enforcement Administration, allegedly resulting in the arrests of members of the drug-trafficking Gonzalez Molina family, which would seek revenge against him. At the time of the death of the patriarch's death in the Dominican Republic, the Dominican authorities responded to the scene of the event (which involved multiple members of two families involved in a violent altercation) and intervened to end the confrontation. Over the years following the events in the Dominican Republic, Ventura-Reyes returned to the Dominican Republic several times without ever being harmed. His wife traveled several more times to the Dominican Republic and was never harmed. The Immigration Judge denied his application for CAT protection, and the Board of Immigration Appeals affirmed.
On appeal, the Sixth Circuit first addressed its jurisdiction over Ventura-Reyes' case, and determined that because he was removable as a criminal alien, they had limited jurisdiction over his appeal, even though he was not charged with deportability for his criminal offenses. Thus, the court would only have jurisdiction over constitutional claims and questions of law. The court then affirmed the Immigration Judge's credibility determination with reference to Ventura-Reyes' witness, determined that Ventura-Reyes' challenge to an evidentiary ruling did not implicate a constitutional claim (and thus, was outside its jurisdiction to consider), and dismissed his challenge to the Immigration Judge's interpretation of the requirement of government acquiescence.
