The Necessary and Proper Clause is commonly called what?

• A. The Elastic Clause
• B. The Necessary and Proper Clause
• C. The Commerce Clause
• D. The Supremacy Clause

Answer: (B)

The phrase commonly used is the Elastic Clause. This nickname comes from how the clause authorizes Congress to make laws that are necessary and proper for carrying out its enumerated powers, allowing a flexible, stretchable approach to power. While its formal name is the Necessary and Proper Clause, the word elastic captures how courts and commentators have understood that it enables implied powers beyond what is listed explicitly. Historical debates and early Supreme Court decisions, like McCulloch v. Maryland, helped cement this flexible interpretation. The other options refer to different parts of the Constitution—the Commerce Clause deals with regulating interstate trade, and the Supremacy Clause establishes that the Constitution is the supreme law—which is why they aren’t the common nickname for this clause.
