What happens if all government powers are concentrated in one organ?

If all government powers are concentrated in one organ, it can lead to an imbalance of power and the potential for misuse or dictatorship. This means that the Legislature, Executive, and Judiciary would not be able to check and balance each other’s actions, leading to decisions that may not be fair or just. Without separation of powers, there could be no accountability, and citizens’ rights could be easily violated. A system with concentrated power threatens democracy and can cause instability in governance. To prevent this, the separation of powers ensures that each organ works independently but cooperates for the welfare of the people.
