Manhattan attorney Scott A. Stern was disbarred Tuesday by a unanimous panel of the Appellate Division, First Department, for physically threatening judges and lawyers.

Stern pleaded guilty to aggravated harassment and stalking in January 2010. He admitted he told a court clerk that he was “seriously considering resorting to violence” against a judge and asked whether he should come back to the courthouse “with a bat.” He also admitted to sending a box cutter to a judge, with instructions to show it to six other judges and to attorneys representing his landlord.
