: They maintain the rule of law amongst Earth and the colonies; consists of a Judge and Jury.
: When the ruling of a planetary court is suspect, the accused my petition for an appeal with the System Courts. Each is made up of a panel of three Sector Judges that have final say in matters that could not be handled by the Planetary Courts.
: The Imperial Seat will judge the accused personally. Under extraordinary circumstances the accused may have their case brought before the Emperor/Empress on Earth.
