Just days after a dozen buildings at Brooklyn’s Atlantic Yards site
were cleaned for demolition the State Supreme Court ruled Wednesday
that the developer does not have rights to some of the properties.

This decision terminates the leases Forest City Ratner bought from
another developer — who had a contract under Prospect Height’s
property owner Henry Weinstein.

The judge said the leases of two buildings had been passed off to Ratner without Weinstein’s approval.

Full control was given back to Weinstein.

An attorney for Ratner says Weinstein plans to appeal the decision.
He also says Ratner does not think this will have any impact on the
progress of construction.
