Plato's Republic[0] specified rules to minimise corruption opportunities. That's what comes to mind anyway. Excerpt from [0]: Socrates points out the human tendency to be corrupted by power leads down the road to timocracy, oligarchy, democracy and tyranny. From this, he concludes that ruling should be left to philosophers, who are the most just and therefore least susceptible to corruption. This "good city" is depicted as being governed by philosopher-kings; disinterested persons who rule not for their personal enjoyment but for the good of the city-state (polis). The philosophers have seen the "Forms" and therefore know what is good. They understand the corrupting effect of greed and own no property and receive no salary. They also live in sober communism, eating and sleeping together. [0]: https://en.m.wikipedia.org/wiki/Republic_(Plato) https://en.m.wikipedia.org/wiki/Republic_(Plato)
