The Necessary and Proper Clause, found in the U.S. Constitution, grants Congress the power to make laws needed to carry out its enumerated powers. This clause has been a source of debate since its inception, with supporters arguing for flexibility and critics fearing federal overreach. Key Supreme Court cases have shaped the interpretation of this clause over time. These rulings have generally upheld a broad view of congressional authority while recognizing some limits to prevent infringement on state sovereignty or individual rights.
