    • Cooley Wins Major Fourth Circuit Victory for Pro Bono Client Trokon Diahn

    May 7, 2026

    Cooley won a major victory on behalf of its pro bono client Trokon Diahn after the US Court of Appeals for the Fourth Circuit granted his petition for review, vacated his removal order and remanded his case for further proceedings. In its published decision on May 5, 2026, the court addressed administrative exhaustion and the scope of immigration judges’ obligations in cases involving pro se respondents. The Cooley team representing Diahn on appeal included partner Raymond P. Tolentino and associate Sahar Atassi, who presented oral argument on behalf of Diahn in the Fourth Circuit.
