I would gather this mechanic didn’t survive into Mongoose.
The harassment one, kinda. The bribery one, no. (At least not in the basic rulebook... AFAIK MgT suffers from severe splatbook rule metastasis.)
At a level L, the laws are so extreme and pervasive yet society must function, that almost every thing can be worked out, maybe even murder.
The bribery roll mechanism is for minor infraction/harassment, but to me it always meant level of corruption and a wry comment on the realities of humans needing room to function.
When thinking about extreme law levels, I am always reminded of this quote from the beginning of "Nineteen-Eighty-Four":
The thing that he was about to do was to open a diary. This was not illegal (nothing was illegal, since there were no
longer any laws), but if detected it was reasonably certain that it would be punished by death, or at least by twentyfive
years in a forced-labour camp.
The end point of increasing state authority is indeed that: Completely arbitrary exercise of power over its subjects, possibly maintaining the purely fictional appearance of 'law' but in this case dismissing even that. Nothing is illegal, thus anything can be illegal. The authorities decide that on a whim. There is no reason, no principle, no counsel to help you. Being spared is subject to the same arbitrariness as being found in transgression in the first place.
