McCulloch v Maryland involved the interplay of which constitutional provisions?

• A. Elastic/Necessary and Proper Clause and Supremacy Clause
• B. Commerce Clause
• C. Due Process Clause
• D. Equal Protection Clause

Answer: (A)

The main idea tested here is how federal power is exercised and maintained over state action. McCulloch v Maryland hinges on two constitutional provisions working together. First, the Necessary and Proper Clause (the Elastic Clause) gives Congress the power to do what is needed to execute its enumerated powers, even if those specific actions aren’t listed in the Constitution. The Court reasoned that creating a national bank is a legitimate means to carry out core duties like handling taxes, borrowing money, and regulating currency, so Congress could charter one even without explicit wording authorizing a bank.

Second, the Supremacy Clause establishes that federal law is the supreme law of the land and cannot be trumped by state laws or actions. Allowing Maryland to tax the national bank would obstruct federal operations, undermining the government’s ability to function as designed. By combining these two ideas, the case shows how Congress can use implied powers to achieve its constitutional ends, and how federal actions prevail over state attempts to impede them. The other clauses listed—Commerce, Due Process, and Equal Protection—aren’t the central justification in this decision, though they appear in other contexts.
