Which constitutional principle is demonstrated by the separation of powers?

The principle of separation of powers is fundamentally about dividing governmental authority among different branches, specifically the legislative, executive, and judicial branches. This division is intended to prevent any single branch from gaining too much power and encourages a system of checks and balances. Each branch has its own specific functions and responsibilities, and they can regulate each other's actions, ensuring accountability and preventing the abuse of power.

In this context, checks and balances work in tandem with the separation of powers by allowing one branch to limit the power of another. For example, while the legislative branch makes laws, the executive branch is responsible for enforcing those laws, and the judicial branch interprets them. This interplay is essential to the functioning of a democratic government and is a safeguard against tyranny and autocracy.
