A Yahoo media executive fired from the internet company last year has filed a lawsuit claiming a job review process implemented by Chief Executive Marissa Mayer was used to cut men from executive ranks and lay them off illegally, court papers showed.

Scott Ard, a former senior editorial director at Yahoo, filed the lawsuit in California’s Northern District Court in San Jose on Tuesday, saying the company violated federal civil rights and employment regulations.

Yahoo spokeswoman Carolyn Clark said in a statement that the lawsuit had no merit and called the performance review process “fair.”

The lawsuit is the second this year accusing Yahoo of discrimination against men, and targets one of the highest-profile Silicon Valley female executives, Mayer, who is in the middle of divesting Yahoo’s core assets after failing to turn the company around.

The lawsuit also claims former Chief Marketing Officer Kathy Savitt “intentionally hired and promoted women because of their gender.”
