More than 170 GCs and chief legal officers have signed an open letter to big law firms, lamenting partnership intakes that "remain largely male and largely white" and saying that their companies will divert legal spend to firms that commit to diversity and inclusion.

The letter has been signed by chief legal officers in a variety of industries, including those in technology, retail, media, hospitality and financial services, at companies including Cable & Wireless Communications, Google Fiber, Etsy, Heineken USA, Mozilla, Waymo, Lyft, Getty Images and S&P Global Ratings.

"We, as a group, will direct our substantial outside counsel spend to those law firms that manifest results with respect to diversity and inclusion, in addition to providing the highest degree of quality representation. We sincerely hope that you and your firm will be among those that demonstrate this commitment," reads the letter.

The letter and signatures were shared with ALM and also posted on a general counsel group page on LinkedIn. Many general counsel who signed the letter also plan to email copies to the firms they work with and request that they share it with all their partners, said Michelle Fang, who spearheaded the letter and is chief legal officer at car-sharing company Turo.

The letter is a direct result of the discussion sparked last month by Paul Weiss Rifkind, Wharton & Garrison and other law firms appearing to promote few women and minorities to partner in their most recent round of promotions. (Paul Weiss chair Brad Karp has since said the firm "can – and will – do better" and has outlined steps the firm has taken to address the issue.)

Fang said a large network of general counsel began discussing law firms that had very diverse promotion classes and those that didn't, and they agreed an open letter to firms would have a broader message compared with individual conversations between firms and general counsel.

"We applaud those firms," the letter reads, "that have worked hard to hire, retain and promote to partnership this year outstanding and highly accomplished lawyers who are diverse in race, colour, age, gender, gender orientation, sexual orientation, national origin, religion, and without regard to disabilities."

"At the same time," the letter continues, "we are disappointed to see that many law firms continue to promote partner classes that in no way reflect the demographic composition of entering associate classes. Partnership classes remain largely male and largely white."

While those lawyers in non-diverse new partner classes worked hard and deserved success, the letter says, "We also know that there are women, people of colour" and others who are equally deserving but haven't been rewarded.

"We are left to wonder if you and your partners value diversity enough to put into place programmes to develop, promote and retain talented and diverse attorneys," the letter adds.

"Collectively, our companies spend hundreds of millions of dollars annually on legal services and we are committed to ensuring equality in the legal profession," states the letter. "We expect the outside law firms we retain to reflect the diversity of the legal community and the companies and the customers we serve."

'Bottom line' incentive

The letter is meant to address firms that have taken a variety of approaches to diversity, Fang said.

For those firms that have prioritised diversity efforts, Fang said the letter will give "validation and support that they may need with partners to keep doing more of it". For those firms that are trying but not doing enough to hire and promote diverse lawyers, she said, it gives them the incentive to recommit.

And for those firms not at all focused on improving diversity, it provides an ultimatum. "If they don't continue to invest in these areas, it will ultimately hurt their bottom line. These diversity and inclusion efforts have a good return on investment," she said. "It will bring them more clients, more talented lawyers and more cases."

Fang, volunteering to take the lead in drafting the letter, worked with other general counsel in writing it. The letter, which is still open for signatures, spread beyond a women's general counsel group to many others' professional networks.

In interviews, several general counsel ticked off reasons why diversity in law firms mattered, from ethical and equality principles to having an effect on the outcome of cases.

"The only way you can flesh out an idea is with diversity of opinion and that needs to be reflected in the diversity of peopling giving us the opinion," said Lyft general counsel Kristin Sverchek, who signed the letter. She said Lyft is considering mandating diversity goals for the law firms it works with, after sharing the letter with firms.

Thomas Chow, a general counsel at online advertising platform PubMatic, said he signed the letter because he has found law firms "need to have repeated and continuous feedback" about the importance of diversity and inclusion at their firms. Sometimes firms trumpet their efforts, but "a lot of the times it feels like lip service when we look at their partner rosters" or promotion announcements, he said.

Chow said the letter was also important to encourage racial and ethnic diversity as well as gender diversity in firms.

Amy Keating, general counsel of Mozilla, the organization behind the popular Firefox web browser, said she signed it because she believes collective voices "are powerful voices for change, and especially so when those voices are clients".
