This fall, the U.S. Supreme Court takes up the case of R.G. & G.R. Harris Funeral Homes v. EEOC. The case involves the contours of Title VII’s prohibition on sex discrimination in employment, but will have broad implications for women and girls who participate in competitive sports.

The specific dispute before the high court arose in 2013, when a funeral home employee known as Anthony Stephens told the company’s owner that, after scheduled time off, he would return to work as Aimee Stephens and use female pronouns. The owner of the funeral home decided to terminate his professional relationship with Stephens.
