Casino operator Wynn Resorts has been hit with yet another lawsuit in the seemingly endless fight over its right to operate gaming in Massachusetts.

On Tuesday, Massachusetts media reported that Sterling Suffolk Racecourse, which formerly owned the Suffolk Downs racetrack in East Boston, is suing Wynn Resorts in federal court for allegedly conspiring to fix the application process that resulted in Wynn being awarded the sole Boston-area casino license in 2014.

Specifically, the lawsuit alleges that Wynn conspired to “fix the application process, circumvent laws in place to prevent the infiltration of mob elements, and interfere and eliminate various regulations aimed at protecting the public at large.”

Said mob elements are a reference to Charles Lightbody, a convicted felon who co-owned the plot of land that Wynn purchased as the new home of its Encore Boston Harbor venue (formerly Wynn Boston Harbor), which is slated to open in June 2019. The other former co-owners are also defendants in the new Suffolk suit.
