A hearing is scheduled for Monday in the case of Constance McMillen, the Mississippi high school student who is suing her school district because it canceled the prom rather than allow her to attend with her girlfriend.

McMillen, who is being represented by the ACLU, seeks to force the Itawamba County School District to hold the prom for Itawamba Agricultural High School on April 2. Same-sex prom dates are prohibited by the district, located in northern Mississippi near the Alabama state line.

Documents filed in federal court Tuesday detail what McMillen faced when she asked to bring her girlfriend to the prom and wear a tuxedo, according to the Associated Press:

“In the court documents, McMillen said Rick Mitchell, the assistant principal at the school, told her she could not attend the prom with her girlfriend but they could go with ‘guys,’” reported the AP. “Superintendent Teresa McNeece told the teen that the girls should attend the prom separately, had to wear dresses and couldn't slow dance with each other because that could ‘push people's buttons,’ according to court documents.”
