Attorneys for Swiss banking giant UBS and the U.S. Justice Department differed Wednesday on how close they are to settling a dispute over an Internal Revenue Service demand for 52,000 names of American account holders who may have skimped on their taxes.

Bank attorney Eugene Stearns, a name partner with the Miami firm Stearns Weaver Miller Weissler Alhadeff & Sitterson, urged U.S. District Judge Alan S. Gold to set another status conference this week, saying he felt the Swiss and U.S. governments were close to a settlement, which could be “minutes away.”
