What does the Interstate Commerce Clause authorize Congress to do?

• A. Regulate trade between states
• B. Enforce laws within states
• C. Decide state boundary disputes
• D. Control state tax laws

Answer: (A)

The Interstate Commerce Clause, found in Article I, Section 8 of the U.S. Constitution, grants Congress the power to regulate commerce among the states. This authority is crucial because it allows the federal government to create a cohesive national market and address economic activities that cross state lines. By giving Congress the ability to regulate trade between states, this clause helps prevent individual states from enacting conflicting regulations that could hinder interstate commerce or create barriers to trade. This foundational power has been the basis for various landmark legislation and Supreme Court rulings that have shaped U.S. economic policy and practices.

The other options do not align with the specific intent of the Interstate Commerce Clause. For instance, enforcing laws within states falls under state jurisdiction, while deciding state boundary disputes and controlling state tax laws are not within the powers granted to Congress by this clause.
