Law in Metairie
All legal authority comes from the Barons, specifically the three high houses of Cimitiere, La Croix, and Samedi. Below them are the lesser houses, whose fortune hangs upon the Barons, who have been known to raise new houses or strip the lands and titles from those who displease them.
Within Perish, justice is dispensed by the Constabulary, and rumors hint of a secret police force (known only as the Agency) that works directly for the Barons. Matters of law are handled by the High and Low Courts. Low Courts are supervised by city magistrates, while the High Courts are convened by one or more Barons.
Justice outside the city is meted out by the Circuit Courts and their enforcement arm, the Rangers of Metairie. A Circuit Court Justice appointed by the Barons is a terrible thing to cross. Lawmen of any stripe are expected to assist any Justice or Baron when requested—and yes, this can get tricky if two or more of these worthies issue conflicting orders!
