McCoy v. Union Elevated Railroad

Background

A hotel owner in Chicago sued several companies after an elevated railroad (the “loop”) was built in front of his building in 1896–97. He said the railroad’s noise, smoke, dirt, blocked light, reduced privacy, and obstructed access harmed the hotel and lowered its market value. The owner’s estate sought money for the alleged damage. At trial a jury favored the railroad companies, and the Illinois Supreme Court approved the trial court’s use of evidence showing that the railroad also increased neighborhood travel and raised property values.

Reasoning

The core question was whether Illinois could require juries to consider benefits from the railroad—like increased travel that raised market value—when deciding if a property was damaged. The owner argued this rule denied him the constitutional right to just compensation. The Supreme Court reviewed whether the state rule deprived the owner of property without due process. It held that allowing juries to consider actual increases in market value from the public improvement did not amount to a deprivation of fundamental rights. The Court explained owners do not have a guarantee to gain from a public improvement and that considering measurable benefits can legitimately reduce a damage award.

Real world impact

The decision affects owners next to public works. When a public project both harms and increases market activity, courts may count the measurable market gains against claimed losses. The ruling affirmed the lower judgment for the railroad companies and left the Illinois rule in place.
