Final answer:
The principle of checks and balances in the United States Constitution was further enhanced by the addition of the Bill of Rights, the establishment of the three branches of government, and the Supreme Court's power of judicial review.
Step-by-step explanation:
The principle of checks and balances in the United States Constitution was further enhanced by several events that occurred after its ratification. One event was the addition of the Bill of Rights, which provided specific protections for individual rights and placed limitations on the powers of the government. For example, the First Amendment guarantees freedom of speech, religion, and the press, while the Fourth Amendment protects against unreasonable searches and seizures.
Another event was the establishment of the three branches of government - legislative, executive, and judicial. Each branch has its own powers and responsibilities, and they are designed to check and balance each other. For example, the president can veto laws passed by Congress, but Congress can override the veto with a two-thirds majority.
Additionally, the Supreme Court's power of judicial review has further enhanced the principle of checks and balances. It allows the Court to review and declare laws or actions of the other branches unconstitutional. This ensures that no branch becomes too powerful and prevents the violation of individuals' constitutional rights.
