In the Court proceedings both Rabb and Brumby appear in a civilian court, the Supreme Court of New South Wales, a state court in Australia, wearing "Court Dress", meaning black robes, wing stiff collared shirts, bands (ruffles in lieu of a tie), and wigs.
Being given dispensation to appear as counsel, lawyers, they would not be required to wear the bands and wig, but rather either their uniform, as Police Prosecutors wear in the Magistrates or County Courts, or simply wear a dark double-breasted, three piece or mourning suit.
Mic Brumby's insignia on his uniform alternates between "Lieutenant-Commander" and "Commander" throughout the episode.
While in court in Sydney, Harm refers to a fictional "Boone County" in Tennessee, whereas no such county exists in Tennessee.
