SACRAMENTO — A State Bar leader said Monday that he and others will ask the chief justice and legislators to split the lawyer oversight agency into a board focused on admissions and discipline and a nonprofit that would effectively serve as a trade association for attorneys.

Dennis Mangers, a nonlawyer member of the bar’s board of trustees, told a bar task force meeting in San Francisco that he was “no longer interested in tinkering around the edges” of what he called “a grossly dysfunctional organization.”
