The Sixth Circuit granted Maher Sabri Hanna’s petition for review, vacated the Board of Immigration Appeals’ (BIA) decision denying his claim for deferral of removal under the Convention Against Torture (CAT), and remanded the case to the BIA. The court held that the BIA and Immigration Judge failed to conduct a required aggregate analysis of the risk of torture. Under Sixth Circuit precedent, an adjudicator must assess whether the cumulative probability of torture from all alleged sources—Hanna’s status as a Chaldean Christian, his criminal history, Americanization, lack of family in Iraq, and lack of identity documents—exceeds 50%, rather than evaluating each factor in isolation. The court found the lower decisions indicated an individualized assessment that did not clearly address the aggregate risk, necessitating remand for a proper qualitative evaluation. Additionally, the court addressed Hanna’s claim that the BIA acted arbitrarily and capriciously by affirming the Immigration Judge’s refusal to qualify Daniel Smith as an expert witness on Iraqi country conditions. While the IJ admitted Smith’s testimony as a percipient witness, the BIA rejected his qualification as an expert based on his lack of formal education and peer-reviewed work, citing inconsistent prior determinations in other cases without explanation. The court applied the arbitrary and capricious standard, ruling that the BIA’s reliance on the fact that prior decisions were unpublished and the uncertainty regarding evidence presented in those cases was insufficient to explain why Smith should not be qualified as an expert in this case where he had been previously recognized. Consequently, the BIA was remanded to adequately explain its reasoning regarding the witness qualifications consistent with controlling precedent.
