The widening war between Donald Trump and his former lawyers at Morrison Cohen can proceed on a new front, a New York state judge has ruled. Trump sued Morrison Cohen and partner Y. David Scharf last year for allegedly treating him like a “cash cow” and overcharging him in a case.

In August, he sued the New York law firm again for allegedly invading his privacy by touting his name on its Web site as a past client. Morrison Cohen has its own claim against Trump for $470,000 in unpaid legal bills.
