Michael Rappaport writes, in answer to Orin Kerr’s question about private takings, “why did the Framers not write the Clause more explicitly to prohibit private use takings…? [I]t was regarded as unnecessary. No one thought that a taking for private use was legitimate.” Yes, and we know that because they said that “[n]o person shall be...deprived of...property, without due process of law.”
Properly understood, the Due Process Clause is a prohibition on private takings. The Fifth Amendment says, property shall not be taken for private use (the Due Process Clause) and if it’s taken for a public use, we’ll pay just compensation (the Takings Clause).
