A defense motion asking the judge scheduled to sentence former state comptroller Alan Hevesi to step down from the case due to a conflict of interest should be denied, prosecutors insist.

In a brief filed Monday, the New York State Attorney General’s Office argued that Manhattan Supreme Court Justice Lewis Bart Stone’s fiduciary and personal relationship with the estranged father of Mr. Hevesi’s lawyer, Bradley D. Simon, is “too attenuated” from Mr. Hevesi to call the judge’s impartiality into question.
