Appeals

Lawyers at the Firm know that practicing before appellate courts requires a different set of skills than trial court litigation. We have extensive experience representing companies, trade associations, and individuals in matters ranging from commercial disputes to technical federal environmental rulemakings and everything in between.

Our appellate team includes former law clerks for federal and state appellate courts, and we understand how appellate judges think.  Attorneys in our appellate practice regularly practice in state appellate courts, the U.S. Circuit Courts of Appeals, and in administrative appeals in district courts.

From defending favorable trial court rulings to stepping in at the appellate level, the Firm’s appellate attorneys are well-equipped to address the unique challenges that appellate litigation poses.
