Mohegan Sun is joining a lawsuit against the Massachusetts Gaming Commission after the decision last year to award Greater Boston’s casino license to a rival.
The suit was originally filed in Massachusetts State Court last October by the City of Revere, where Mohegan Sun had sited its proposed bid. Revere was joined in filing by a labor union which represents workers at the Suffolk Downs Racetrack. The Mohegan proposal was to locate a resort casino at the racetrack; when the bid failed, the racetrack was shut down.
The lawsuit alleges that the regulators failed to follow the law in awarding the license to Wynn Resort's Everett project, and that they gave the rival bid preferential treatment. Mohegan Sun says the commissioners allowed Wynn to resubmit significant portions of its bid, while Mohegan was not given the same opportunity. The suit also says the commission awarded the license despite a land deal that ‘‘appears to enrich individuals affiliated with criminal enterprises and who are the target of federal and state indictments.’’
A spokeswoman for the commission said the licensing process was ‘‘comprehensive, thoughtful and fair’’ and declined to address specific points in the lawsuit.
Boston and the City of Somerville have also separately sued the commission over their decision.
