Fitzgerald v. Racing Assn. of Central Iowa

Background

A group of racetrack operators and an association of dog-track owners sued after Iowa changed its gambling laws. In 1989 Iowa authorized slot machines on riverboats and taxed their adjusted revenues up to 20 percent. In 1994 the State let racetracks add slot machines and imposed a graduated tax that would rise to a 36 percent top rate, while leaving riverboat rates at 20 percent. The Iowa Supreme Court held that the 20 percent/36 percent difference violated the Federal Constitution’s Equal Protection Clause.

Reasoning

The U.S. Supreme Court reviewed whether that tax difference denied equal protection. Applying the usual deferential test for tax classifications (rational-basis review), the Court asked only whether a plausible policy reason could justify the disparity. Justice Breyer explained that lawmakers could rationally favor riverboats to aid financially troubled river operators, encourage river community development, preserve riverboat history, or protect riverboat operators’ prior reliance on lower rates. Because those are reasonable legislative goals, the tax difference is not arbitrary under the Federal Equal Protection Clause.

Real world impact

The decision reverses the Iowa Supreme Court and lets the State continue taxing racetrack slot revenues at a higher rate than riverboat slot revenues. That outcome leaves tax policy choices to Iowa legislators and officials so long as some plausible policy reason exists. The ruling was not a detailed reworking of constitutional doctrine; it affirms that courts give broad deference to legislative tax classifications.
