Ritsuryo was the Rokugani system of law.
Inspired by the Scorpion magistrate Soshi Saibankan the Otomo Daimyo Otomo Kuchiru wrote a system of penal and administrative law which advocated testimony and honour over physical evidence. It was backed by the Emperor and established as the Empire's fundamental legal code.  It was held an annually conference, Hashira Horitsu, to modify the current laws. 
Any testimony could be always confronted to the ancestors of the samurai, using the Kitsu Sodan Senzo, so no one could be expected to lie with such a jury.  Since the year 53  this practice was avoided as far as possible, since the Soshi once fouled the Kitsu during the reign of Hantei Genji. A Lion general's spirit testified who was his murderer, and after punishment was exacted, the Soshi revealed the Lion general was still alive as their hostage.  As a samurai was expected to lie to protect his family's honour, the testimony of family members was not considered valid during trials.
Kolat Manipulation Edit
The Kolat conspiracy encouraged moving the Emperor's laws away from fact and towards perception. First, it eliminated the need for physical proof of a given deed, the leeway to alter what people would think and see. Second, the timely words of an "honourable man" could provide a smokescreen. Finally, it would turn the people's opinion against the Hantei if the Emperor's word ever ran consistently against the precepts of honour and common sense.
