Current and former professional athletes and players' unions have sued Pittsburgh over a tax levied on visiting pro athletes.
At issue are so-called "jock taxes" typically levied on professional athletes who work for short periods of time in cities.
The Pittsburgh lawsuit argues the city unfairly levies a 3 percent earned income tax on visiting professional athletes while taxing all other residents at 1 percent.
Attorney Stephen Kidder, representing the athletes, tells the Tribune-Review the tax violates the state and U.S. constitutions.
Dan Gilman, Mayor Bill Peduto's chief of staff, declined to comment.
Those suing include former Pittsburgh Penguin Scott Wilson; Kyle Palmieri of the New Jersey Devils; former baseball player Jeff Francoeur; and the players' associations of the National Hockey League, National Football League and Major League Baseball.
