Diversity, Equity and Inclusion (DEI) has always been important, but more recently law firms and in-house counsel pay a lot more attention to this. In-house counsel set minimum standards for diversity on the teams that work for them. Law firms have become much active in hiring and promoting diverse candidates. In particular, the introduction of the Mansfield Rule has supported better practices on DEI. Under the Mansfield Rule (result of a 2016 Women in Law hackathon) and supported by Diversity Labs firms that subscribe to it, require that law firms consider at least 30% women, LGBTQ+ and minority lawyers for significant leadership roles. Among the tools in this category, Leopard Solutions provides objective data on DEI. Diversity Labs is the main driver behind the Mansfield Rule.
