Unprofessionalism can exist only to the extent it is tolerated by the court. Because courts grant the right to practice law, they control the manner in which the practice is conducted. The right to practice requires counsel to conduct themselves in a manner compatible with the role of the appellate courts in administering justice. Likewise, no one more surely sets the tone and the pattern for the conduct of appellate lawyers than appellate judges. Judges must practice civility in order to foster professionalism in those appearing before them.
Members of the court will demonstrate respect for other judges and courts.
