Murr v. Wisconsin

In Murr v. Wisconsin, the Court redefined how to determine private property for a regulatory taking under the Fifth Amendment. Previously, courts have primarily relied on state property principles to determine the relevant unit of property for a regulatory takings claim. However, in this case, the Court adopted a three-factor standard to determine the landowner’s reasonable expectations regarding the treatment of their property. By relying on these factors rather than only on state laws, the Court created a litigation-specific definition of property that could potentially differ from state property boundaries.

The three-factor standard may also give the government an unfair advantage in regulatory takings claims by considering state interests more than once in a takings analysis.
