Lawyers argued Monday over whether a former state judge who handled affordable housing cases should have at least one of his rulings overturned because of his relationship with a developer.

In Trenton, a lawyer for South Brunswick Township squared off against a half-dozen others representing developers and affordable-housing advocates. The township is seeking to have affordable housing rulings made by now-retired Middlesex County Superior Court Judge Douglas Wolfson vacated because of what it alleges is the appearance of a conflict of interest: Wolfson's acceptance of vacations from, and current representation of, Edgewood Properties.

While on the bench, Wolfson handled litigation involving the township, but not Edgewood Properties, according to documents. And Wolfson recused from cases that came before him involving Edgewood.
