One day after a judge rejected Boston's lawsuit to halt a nearby casino, Mayor Martin J. Walsh indicated Friday he was not prepared to end the city's costly legal fight.

The city has spent $1.25 million to bring the lawsuit, in an attempt to block construction of a 24-floor, curved glass tower on the Mystic River waterfront a short distance from Boston's Charlestown neighborhood.

Walsh had argued that the new casino will further snarl traffic in an already-congested Charlestown.

But in her 24-page ruling Thursday, Judge Janet L. Sanders delivered a stunning blow to that claim, dismissing the lawsuit and deciding that the state Gaming Commission had acted properly in issuing a casino license to Wynn Resorts.


In a brief encounter with reporters in City Hall, Walsh defended the city's high-priced legal challenge.

"It's worth it. I'm fighting on behalf of the people of Boston,'' Walsh said. "I'm not going to roll over and not fight for the people of Boston. I'm not going to roll over and … just say 'OK, so be it.' … That's not my job. "

In her ruling, Sanders chided Boston and its lawyers for "inflammatory descriptions," "spurious" claims and "hyperbole" that "tend only to obscure the factual allegations."

She said the City of Boston had failed to show it had suffered the kind of injury that under the Gaming Act would have allowed it to pursue its lawsuit.

Walsh said Friday morning that he had not read the court decision, but plans to scrutinize it before determining how to proceed, including whether to appeal.

"You never know what a court is going to do,'' Walsh said. "It's kind of one of those things. I can't sit here … and say I'm excited about the judge not proceeding with the case. But we'll see what happens. My job as mayor is to work on behalf the people of the city. I feel I am doing that. I've been doing that and will continue to do that."


The mayor said city officials will continue to meet with representatives of Steve Wynn, the gambling mogul who is planning to build a $1.7 billion casino in Everett, at the Charlestown border.

Walsh said the two sides have had "good dialogue," noting that inflammatory public rhetoric between the two sides has subsided.

In Everett, Mayor Carlo DeMaria called the judge's dismissal of Boston's lawsuit another positive step for his city, saying the casino project would produce roughly 4,000 construction jobs and 4,000 permanent jobs when the casino opens.

"This project has always been about jobs -- jobs for Everett residents and jobs for residents of the entire greater Boston region,'' said DeMaria. " This development will enhance the quality of life for our residents, and provide benefits long into the future."
