What it's about

The Supreme Court agreed with the Wisconsin Court of Appeals that the lots should be treated as one property for that analysis and affirmed its ruling.

The lots were along Wisconsin’s Lower St. Croix River. A local rule barred the Murr family from selling or developing them separately because neither had enough buildable land.

The dispute centered on whether the relevant property was two separate lots or one combined property.

Question presented

In a regulatory taking case, does the "parcel as a whole" concept as described in Penn Central Transportation Company v. City of New York, 438 U.S. 104, 130-31 (1978), establish a rule that two legally distinct, but commonly owned contiguous parcels, must be combined for takings analysis purposes?

What the Court decided

Holding

The State Court of Appeals was correct to analyze petitioners’ property as a single unit in assessing the effect of the challenged governmental action. 2015 WI App 13, 359 Wis. 2d 675, 859 N. W. 2d 628, affirmed.

From the opinions

“In my view, it would be desirable for us to take a fresh look at our regulatory takings jurisprudence, to see whether it can be grounded in the original public meaning of the Takings Clause of the Fifth Amendment or the Privileges or Immunities Clause of the Fourteenth Amendment.”

— Justice Thomas(dissent)

What's next

The Wisconsin appeals court’s ruling remains in place; the Supreme Court did not send the case back for further proceedings.
