A teenage lesbian in Fulton, Miss., who sued her school district over its ban of same-sex prom dates has accepted an offer to settle the case.

American Civil Liberties Union attorneys representing Constance McMillen filed notice Monday in U.S. District Court to accept a judgment offer from the Itawamba County School District to pay $35,000 US, plus attorney's fees.

As part of the agreement, the school district also said it would follow a policy not to discriminate based on sexual orientation and gender identity in any educational or extracurricular activities.

The ACLU said the case is precedent-setting because the district is the first in Mississippi to implement a policy banning discrimination and harassment on the basis of sexual orientation and gender identity.

"I'm so glad this is all over," McMillen said in a statement Tuesday. "I won't ever get my prom back, but it's worth if it changes things at my school."

A call to the school district in north Mississippi seeking comment wasn't immediately returned.

The ACLU filed a lawsuit in March when the district cancelled a prom on April 2 at Itawamba Agricultural High School after McMillen asked to bring her girlfriend to the event and wear a tuxedo.
