Section 9 typically refers to a specific part of a legal document, such as a constitution or a contract, outlining particular rights, responsibilities, or regulations. In the context of the U.S. Constitution, Section 9 addresses limitations on the powers of Congress, ensuring that certain actions cannot be taken without due process or specific legal authority. For example, Section 9 prohibits Congress from banning the importation of slaves before 1808 and requires that individuals cannot be detained without a trial. This section is crucial for maintaining checks and balances within the U.S. government and protecting individual liberties.
