Which principle of the Constitution serves to distribute authority among different branches of government?

The principle that serves to distribute authority among different branches of government is the Separation of Powers. This concept is foundational to the structure of the United States government, as it divides the government into three distinct branches: the legislative, executive, and judicial. Each branch is endowed with its own powers and responsibilities, ensuring that no single branch becomes too powerful or encroaches on the functions of the others.

By establishing this separation, the Constitution aims to create a system of governance that is both efficient and equitable. Each branch has specific roles—legislation is conducted by Congress, the executive is responsible for enforcing laws, and the judiciary interprets them. This division helps to safeguard against tyranny and promotes a system of accountability.

While checks and balances are influential in maintaining oversight among the branches, it is the separation of powers that primarily dictates how authority is allocated within the government. This principle underpins the entire framework of American governance and is crucial for maintaining the rule of law and protecting individual liberties.
