Massport is facing the city of Boston, which wants to keep the injunction in place. According to Bill Manning, of Communities Against Runway Expansion, there was a large turnout from the area near the airport as well as the South Shore towns that have objected to the new runway because they are in the plane's flight path.

Lifting the injunction is crucial to Massport's plan to build the new runway. The Federal Aviation Administration gave the project its conditional approval last summer.

But Manning tells GlobeSt.com that the injunction is just one of three legal initiatives the group is pursuing to prevent the runway from being built. The group filed a Freedom of Information Act for the original Mitre Report, on which the FAA based its decision. Manning says his group believes that Massport's projections for the runway were "rosier than what the report actually said." CARE is also challenging the FAA's Record of Decision on the new runway in federal court.

"If the injunction gets lifted that means [Massport] cleared the local court but we'll go to federal district court and fight them on that level," says Manning.
