The American Civil Liberties Union (ACLU) has filed suit against the largest healthcare network in Washington State after chest reconstruction surgery scheduled for a woman who identifies as a man was cancelled and she had to obtain the operation elsewhere.

According to the complaint filed by the ACLU, the 30-year-old woman, who goes by the name Ari Robbins, has been diagnosed with gender dysphoria, “a serious medical condition codified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) and International Classification of Diseases (ICD-10).”
