Mohegan Sun is suing Massachusetts gambling regulators over their decision to award the Boston-area casino license to a rival.
The Connecticut-based casino company is joining a Superior Court lawsuit filed late last year by the city of Revere, Massachusetts and a labor union representing workers at the Suffolk Downs horse racing track.
Mitchell Etess, CEO of the Mohegan Tribal Gaming Authority, said on Wednesday the company has never filed suit to challenge a casino license decision, but felt compelled to in this case because of the many issues around what he called a "gravely flawed" decision.
The lawsuit seeks to vacate the Massachusetts Gaming Commission's decision to award the license to Wynn Resorts, which plans a casino in Everett.
Mohegan Sun had proposed a resort at Suffolk Downs in Revere.
