Charlie is a highly experienced attorney who has engaged primarily in appellate practice during his legal career, which has also included holding public positions as executive director and lead administrator of two government agencies. His appellate practice has encompassed all state and federal appellate courts in Florida, with occasional practice before other federal circuit courts of appeal.
In a career that spans more than 30 years, Charlie has more than 100 reported decisions in state and federal courts. His notable cases include a 1989 victory before the Supreme Court of Florida that clarified the scope of the contemporary arbitration code with respect to enforcement of erroneous legal determinations by the arbitrator. He also won a unanimous reversal several years later before the Supreme Court of Florida that resulted in a modification of state law to adopt federal forum non conveniens standards.
Charlie earned his law degree from George Washington University, and spent almost 15 years as a partner in the appellate practice department of one of the largest law firms in the United States before entering public service. It was there that he and John met. He has prevailed in numerous state and federal commercial appeals. He has also successfully handled numerous pro bono matters supporting children’s rights.
Charlie currently serves as chair of the Appellate Court Rules Committee General Practice Subcommittee and on a community-based not-for-profit board in Miami.
