Joseph P. Murr, Petitioners v. Wisconsin

Summary

The Court affirmed the Wisconsin Court of Appeals, holding that for regulatory takings analysis, the relevant parcel is determined by a multifactor test assessing state law treatment, physical characteristics, and prospective value. Applying this standard, the Court concluded petitioners' adjacent lots constituted a single parcel, and thus the regulations did not deprive them of economically beneficial use. Chief Justice Roberts, dissenting, argued state law should define parcel boundaries.
