Developer Bruce Ratner says he is confident ground will be broken this year on the proposed Nets arena in Brooklyn, as his controversial Atlantic Yards project cleared another hurdle Friday.

A panel of four appellate judges ruled unanimously the state can use eminent domain to go forward with the project because of the public benefits associated with the plan.

Proponents say the estimated $4 billion project will bring jobs and affordable housing to Prospect Heights as well as a professional basketball team to Brooklyn.

Critics say the plan will force people out of their homes and businesses.

The group Develop Don't Destroy Brooklyn, which has been fighting the project, says it will appeal the judges' decision.

Ratner says he expects the new home for the Nets will be ready for the 2011-2012 season.
