California broke new ground for women when Governor Jerry Brown signed the first-in-the-nation requirement that publicly traded companies in the state have at least one woman on their board of directors by the end of 2019, and two or three by the end of 2021. But last month, the law was deemed unconstitutional.

On May 23, California Secretary of State Shirley Weber announced that she will appeal the California ruling, which will take time and may not be successful. Without formal requirements, we can only hope a growing critical mass of women can change corporate culture that’s still merrily skating along with those unwritten “majority male quotas” that have been firmly in place for centuries.
