Court officer union boss Dennis Quirk has offended New York’s Italian-American Chief Judge Janet DiFiore with a T-shirt suggesting that she’s a mob boss, The Post has learned. Quirk ordered the T-shirts, which have Office of Court Administration written over a graphic of the scales of justice unbalanced, above the words “Organized Crime Association.”

DiFiore, who is New York’s first Italian-American chief judge, sent a letter to Quirk Wednesday blasting the T-shirts, which were worn at union rallies pushing for more court officer hires and a hike in pay. “By insinuating that I, as Chief Judge of the New York State courts, preside over an ‘organized crime association,’ you have publicly attacked the integrity of our entire court family…,” DiFiore wrote in the scathing missive.
