Which statement best describes the Plenary Power Doctrine?

• A. The Supreme Court gives full power to Congress and the President to determine issues of national sovereignty and security, such as immigration laws—even if the law discriminates based on race or nationality.
• B. All statements are true.
• C. The Supreme Court can overturn racist immigration laws by declaring them unconstitutional.
• D. The doctrine can be invoked only after martial law has been declared by the President.

Answer: (A)

The Plenary Power Doctrine centers on broad federal control over immigration and national sovereignty, with the judiciary giving deference to Congress and the President in immigration matters. Because immigration policy is considered a realm of national sovereignty, the Supreme Court historically defers to the political branches, allowing them to shape laws that regulate who may enter or stay in the country. This is why the statement describing the doctrine as giving full power to Congress and the President to determine national sovereignty issues and immigration policies—even when those laws discriminate based on race or nationality—best captures the idea. The other ideas don’t fit as well: the Court is not asserting ongoing power to strike down racist immigration laws under this doctrine, since it emphasizes deference to the political branches; and it is not tied to martial law.
