(SACRAMENTO, Calif.) — Hundreds of California-based corporations must have directors from racial or sexual minorities on their boards under a first-in-the-nation bill signed Wednesday by Gov. Gavin Newsom. The diversity legislation is similar to a 2018 measure that required boardrooms to have at least one female director by 2019. Like that measure, it could face court challenges from conservative groups who view it as a discriminatory quota. Supporters evoked both the coronavirus pandemic that is disproportionately affecting minorities and weeks of unrest and calls for inclusion that followed the slaying of George Floyd in May in the custody of Minneapolis police. After Floyd’s death, many corporations issued statements of support for diversity, but many haven’t followed through, said Assemblyman Chris Holden (D-Pasadena), who co-authored the bill. “The new law represents a big step forward for racial equity,” Holden said.
