Rheinland is a fascist (minus any apparent form of genetic discrimination) democratic state without a standard of presumption of innocence, up to and including in prosecutions of Rheinwehr personnel. It appears to legislate through a 2 chamber Reichstag, yet it's Kanzler is worshipped via it's state religion, which may suggest some aspects of Rheinland society are in a sort of civil war with each other.
Regardless of it's process of legislature, Rheinland justice is administered by senior Kriegsmarine command, and is generally swift, immediate and permanent. It is also biased according to faction. Generally, corporations from Rheinland are given more chances then quasilegal groups like the Junkers or Zoners.
I would imagine that civil cases would likely be handled by more formal courts, but Kriegsmarine tribunals seem to handle most criminal cases when they occur in space. Presumably, the Heer would handle land criminal cases, or the Polize.
Also, I found the typo referencing the Sturmabteilung rather amusing, considering some might confuse it with the Southern Alliance, and that some may also assume (Wilde) that Nomadic infestation occured in the Third Reich.
