Your answer was - on reflection - inadequate.
N put in place many systems of checks and balances, intended to eradicate - or at least, on the surface of it - limit corruption and theft from the state.
Or so we are repeatedly told.
However, when one of his close buddies is caught with his arm up to the elbow in the cookie jar, what does he do?
Does he convene the court, as prescribed? NO.
Does he imprison his buddy? NO.
He throws his own rule book out of the window, lets his buddy keep half the loot and removes him from Hamburg.
Or was B subjected to further punishment?
In other words, N is another example of `Don`t do as I do, do as I say`.
If you were an old crony of N`s, you could get away with quite a lot - about 50% actually.
