The Necessary and Proper Clause is a part of the United States Constitution, specifically found in Article I, Section 8. This clause grants Congress the power to make laws that are necessary and proper for carrying out its enumerated powers. It allows Congress to create laws that are not explicitly listed in the Constitution but are essential for executing its responsibilities. This clause is often referred to as the Elastic Clause because it provides flexibility in legislative powers. It has been the basis for many important laws and Supreme Court decisions, helping to shape the balance of power between the federal government and the states.
