Chessie has secured wins in Martinez v.

There, Chessie represented individuals and businesses in a range of complex civil cases and class action lawsuits, regularly arguing cases in both federal and state court. While at the firm, Chessie developed a dynamic pro bono practice, partnering with the ACLU on several amicus briefs that advocated for criminal justice and immigration-related reforms. In particular, Chessie was a member of the ACLU's litigation team in Al-Mowafak et al. v. Trump et al., which challenged Trump's original executive order banning refugees and nationals of majority-Muslim countries from entering the United States.
