The concept illustrated by Congress's power to introduce and pass laws is known as legislative authority. This authority reflects the principle of separation of powers, which delineates distinct roles for different branches of government. In this framework, Congress, as the legislative branch, is responsible for creating laws, while the executive branch enforces them and the judicial branch interprets them. This system ensures a check on power and promotes accountability within the government.
