In response to a terrorist threat, Congress enacted a statute authorizing the President to construct security facilities on privately owned land without compensation, and to own and operate the facilities. The President selects a small, unused portion of a large tract for this purpose. The landowner sues to challenge the constitutionality. Which ground provides the best basis for challenge?

• A. The Commerce Clause.
• B. The Due Process Clause of the Fifth Amendment.
• C. The Privileges and Immunities Clause of Article IV.
• D. The Privileges or Immunities Clause of the Fourteenth Amendment.

Answer: (B)

The central idea is that the government cannot take private property for public use without paying just compensation. That protection is provided by the Takings Clause of the Fifth Amendment. Here, Congress authorizes the President to seize privately owned land and use it for security facilities without paying the landowner. That per se taking implicates the Fifth Amendment’s Takings protection, which is typically invoked through the Fifth Amendment's due process framework. So challenging this action under the Fifth Amendment’s Due Process Clause is the strongest constitutional basis, because it directly targets the government’s authority to seize property without compensation.

The other grounds miss the core issue. The Commerce Clause governs regulation of interstate commerce, not government seizures of private land for public use. The Privileges and Immunities Clause of Article IV and the Privileges or Immunities Clause of the Fourteenth Amendment concern different protections related to citizenship rights and fundamental rights, not the government’s power to seize property without compensation.
