The Iroquois system of governing believed in all these three principles:
A.) equality among people, they believed that all people women and men were equal, they even gave strong voice and power to the council women,
C.) self-government, they had representatives of all their brother tribes and formed a confederation to govern their mutual lives.
D.)multi-tiered representation, they had different tiers among their government to secure a democratic voice for all the individuals in their citizens.
There is not evidence however, that they used: B.) checks and balances to pass on laws.
