I'm building an RPG setting inspired by 1700's style myths and stories, a sort of Dick Turpin meets Midsummer Nights Dream. I have a few sticking points, especially in regards to the law; both in how a case was built, brought to trial and convicted, and in how and who the courts answered to most accusations. I know I'm way off of a modern Police force, and the way I've been dubiously dabbling away at the courts is to assume that they are corrupt and inaccessible to all but the wealthy and powerful.
Here's what I have built at the moment: I have three institutions, Magisters, Bailiffs and Wardens, both the Bailiffs and Wardens answer to the Magisters but the Bailiffs have higher jurisdiction than Wardens. Magisters build the cases, assembling evidence, witnesses and arguments, they might act like modern detectives but their actual agents on the ground are the Bailiffs, whose job it is to act as the enforcers to the Magisters, acquiring evidence and bringing criminals to court acting as a sort of beat-cop analogue, lastly the Wardens whose jurisdiction is sharply limited to the forests and specifically in poachers, deserters, highwaymen, cultists and other criminals who make the forest their home, they can bring a case to the Magisters or Bailiffs or can act on their command, but mostly they're a self sufficient group who are capable of enforcing the law on their own terms.
So what else ought I be paying mind to? Any real life analogues or things of significance I'm missing?
