A federal judge has dismissed negligence claims by Con Edison over the destruction of 7 World Trade Center on Sept. 11, 2001.

Southern District Judge Alvin K. Hellerstein, in In re September 11 Litigation, 21 MC 101, said the chain of events that led to the destruction of 7 World Trade Center was “much too improbable to be consistent with any duty” toward Con Edison by builder and developer Larry Silverstein and Citigroup, the successor-in-interest to the building’s primary tenant, Salomon Brothers.
