Nothing about the case has been ordinary. It’s a sexual harassment lawsuit, but it doesn’t involve any men. A company executive was accused, yet the case hasn’t quietly settled. And perhaps most unusual of all, the executive countersued with a defamation claim.

It began in April, when Yahoo Inc. software engineer Nan Shi claimed that her boss had pressured her to have sex. She further claimed that when she broke off the relationship, her boss retaliated with poor performance reviews that ultimately led to her termination.
