Last July, Diversity Lab launched the pilot program for its Mansfield Rule: Legal Department Edition. The program asked the 22 participants, which included PayPal Holdings Inc. and Uber Technologies Inc., to consider 50% of underrepresented groups for internal roles and when hiring outside counsel. The in-house participants were asked to track that data and report it back to Diversity Lab throughout the year.

Leila Hock, director of legal department partnerships and inclusion initiatives at Diversity Lab, said legal departments are in the process of mailing in certifications, and corporations are signing up for the Mansfield Rule: Legal Department Edition 2.0. The second version of the program will extend the certification time from one to two years.
