Nature: It is primitive direct democracy, which only applies to small and few city-states.

Mode: Voting and taking turns to sit in the village may lead to the abuse and misuse of state power.

Consequence: it became a tool for individuals to fight for their rights, leading to political turmoil and decline in the late Athens.
