Ninth Circuit to Hear Plaintiffs’ Appeal re Class Certification in Microsoft Gender Discrimination Lawsuit

On September 20, 2018, the Ninth Circuit Court of Appeals issued an order accepting Plaintiffs’ petition for a discretionary appeal of the District Court’s June 25, 2018 order denying class certification in the Microsoft gender discrimination lawsuit, Moussouris v. Microsoft Corporation, brought by female current and former Microsoft professionals. Plaintiffs seek to represent a class of female current and former employees in Microsoft’s Engineering and I/T Operations professions in the U.S. at stock levels 59 through 67. Plaintiffs allege that Microsoft has engaged in systemic and pervasive gender discrimination with respect to pay and promotions.

A remarkable showing of over 30 national and regional women’s and civil rights organizations supported the Plaintiffs’ request for the appeal. Those organizations are:

  • A Better Balance
  • Alianza Nacional de Campesinas
  • American Civil Liberties Union
  • American Association of University Women
  • Asian Americans Advancing Justice – Asian Law Caucus
  • Asian American Legal Defense and Education Fund
  • California Women Lawyers
  • California Women’s Law Center
  • Center for WorkLife Law at the University of California, Hastings College of the Law
  • Disability Rights Education & Defense Fund
  • Equal Justice Society

  • International Action Network for Gender Equity & Law
  • Lambda Legal Defense and Education Fund, Inc.
  • Legal Aid at Work

  • National Women’s Law Center
  • Public Advocates, Inc.

  • Washington Lawyers’ Committee for Civil Rights and Urban Affairs
  • Women Employed

As the pleadings in the case describe, Microsoft has permitted and facilitated a corporate culture of unchecked gender bias and a Human Resources department that virtually never finds in favor of female complainants alleging gender discrimination. Discovery in this case revealed that from 2010 to 2016, Microsoft’s internal complaint investigation team only substantiated 1 out of nearly 120 gender discrimination complaints made by female technical employees. The disadvantage to female engineers in pay and promotions is the predictable result of Microsoft’s policies and practices and its lack of proper accountability measures to ensure fairness. Plaintiffs further allege that Microsoft has implemented these policies and practices despite knowing that they have a long-standing disparate impact on women.

“We are pleased that the Ninth Circuit will hear Plaintiffs’ appeal,” stated Kelly M. Dermody, the Chair of Lieff Cabraser’s Employment Law Group and co-counsel for the Plaintiffs in the case. “We welcome the Ninth Circuit’s clarification of the class certification standards and believe the evidence here demands that Microsoft’s common discriminatory systems be addressed on a class basis so that women at the company can get justice.”

“This is a terrific development for our clients,” stated Adam Klein, Deputy Managing Partner at Outten & Golden LLP and co-counsel for the Plaintiffs in the case. “We look forward to the appeal to the Ninth Circuit and then proceeding with the merits.”

The case alleges claims under federal anti-discrimination law, Title VII of the Civil Rights Act of 1964, as well as under the Washington Law Against Discrimination. Plaintiffs seek back pay as well as monetary damages, including punitive damages, along with injunctive relief —that is, court-monitored changes to Microsoft’s pay and promotion practices as well as its system for investigating internal complaints.

About the Plaintiffs

Katie Moussouris worked for Microsoft in its Trustworthy Computing Group in Redmond, Washington, for over seven years. She left Microsoft in 2014 and is the founder and CEO of Luta Security, a firm offering solutions architects for vulnerability disclosure or Bug Bounty programs. Holly Muenchow is a current Microsoft engineer, and has worked for the company since 2002. Microsoft’s attempt to dismiss the claims of both women was denied in full.
