The U.S. Justice Department told the U.S. Supreme Court on Wednesday that transgender workers are not guaranteed federal anti-discrimination protections, arguing against the views of the U.S. Equal Opportunity Commission and marking the latest clash between the agencies over the scope of Title VII civil rights.

The EEOC, which has pushed for broader interpretation of sex discrimination under Title VII, brought the lawsuit against a Michigan funeral home after it fired transgender employee Aimee Stephens. The U.S. Court of Appeals for the Sixth Circuit ruled in March that the funeral home unlawfully fired Stephens.

The Justice Department represents the EEOC in matters before the Supreme Court. The brief filed Wednesday by U.S. Solicitor General Noel Francisco, in the case R.G. & G.R. Harris Funeral Home v. EEOC, did not include any EEOC lawyers on the cover sheet, one sign of the conflict between the agencies. The EEOC declined to comment.
