The system of checks and balances consists in the control of power by its own power, and each power would have autonomy to exercise its function, but would be controlled by the other powers. This would prevent any abuse of power by either branch (executive, legislative and judiciary). Thus, although each power is independent and autonomous, it must work in harmony with the other Powers.
Thus, the legislature in my city, and anywhere that uses the system of checks and balances, exercises this system establishing laws that allow the proper functioning of the city, oversees the executive and judiciary, but does not interfere with their work.
