Two forces police Catena, and they divide on one thing: alloy. The Constabulary, the Municipals, handles everything that does not involve it. The instant a Clarity scanner chirps, jurisdiction passes to Meridian Security. Civilians prefer to call the Municipals first, because a civil matter calls down no alloy paperwork.
A Municipals week is half property and a quarter disputes inside one address, and the rest is errands. In no column at all, and the biggest, are missing persons, which are not theirs. A diver who does not come up is a charter matter, which is a Meridian matter, which is a form. The families come to the Municipals anyway, because it is the only counter in the city that will take a statement from someone crying.
Any matter touching alloy discharge is removed from the ordinary lists to the Licensing Tribunal. Removal cannot be opposed, and the Tribunal's calendar is measured in months.
Below the Tribunal there is one court, and it is not called a court. The Small Docket sits four days a week in what was a Loom-era pay office: one magistrate, no jury, a list read at 09:00, and about forty matters a day. A tenancy dispute takes eleven minutes, and the times it goes wrong are the times a person needed forty.
Every landlord's agent knows the trick. If you are going to lose at the Small Docket, say a Legend was present. It does not have to be true, only arguable, and the matter goes upstairs, where it will not be heard this year and the tenant, who needed a decision this month, moves out. The counter-craft is to keep alloy out of it, and everyone in the Fringe knows that too.
Three other venues are not courts at all. The Counting House arbitrates commercial disputes above a certain size, and is fast, expensive and reliable. The Ledger House floor votes on union matters with the book open, and nobody has ever wanted an appeal. The Warrens settle a stall dispute under old dock-labour custom in about ninety seconds, after which the loser is expected to be seen buying from the winner. Catena has never had a jury, and in twelve years of complaint about the Tribunal nobody has proposed one.
