What case affirmed Congress's authority to establish a bank under the necessary and proper clause?

The case that affirmed Congress's authority to establish a bank under the necessary and proper clause is McCullough v. Maryland. This landmark decision, issued by the Supreme Court in 1819, confirmed that the federal government has implied powers beyond those explicitly stated in the Constitution. Specifically, it established that Congress could create a national bank as a means to effectively exercise its enumerated powers, such as regulating commerce and collecting taxes.

The ruling highlighted the flexibility of the Constitution, particularly through the necessary and proper clause, which allows Congress to pass laws deemed necessary to fulfill its constitutional responsibilities. This case was significant in defining the scope of federal power, reinforcing the idea that the government can take actions not specifically enumerated in the Constitution if they are in pursuit of its lawful objectives.

The other cases listed do not pertain to the implications of the necessary and proper clause regarding Congress's powers. They each address different constitutional questions and rights, making them unrelated to the establishment of a national bank.
