Diversity Lab announced Thursday the launch of its inaugural Mansfield Rule: Legal Department Edition with more than 20 corporate legal departments on board to help foster diversity within in-house legal leadership.

The program serves as an extension to the Mansfield Rule, which was designed for law firms to find ways to put underrepresented attorneys on matters and on a path to partnership.

Legal departments in the pilot program track and record who is in their candidate pool and, at the end of the year, the general counsel submits the statistics to Diversity Lab. The program asks legal departments to consider at least 50% underrepresented candidates for internal roles and when hiring outside counsel.
