Last summer nearly 50 law firms signed on to the Mansfield Rule—named after the first woman lawyer in the U.S., Arabella Mansfield—in an effort to close the gap in leadership roles for women and minorities in Big Law.

Next up? Most of the same firms, along with some new ones, are signing on next month for the launch of Mansfield 2.0, which broadens the obligations of participating firms and expands the initiative to include LGTBQ+ attorneys.
