A national LGBT rights organization has asked the U.S. Supreme Court to review the case of a Savannah security guard who was allegedly forced from her job because of harassment.

At its Atlanta office on Thursday, Lambda Legal announced a petition that seeks a nationwide ruling that sexual orientation discrimination violates Title VII of the Civil Rights Act.

In April 2015, Jameka Evans, who now resides in Atlanta, filed a lawsuit in U.S. District Court for the Southern District of Georgia against her former employer, Georgia Regional Hospital. She said the hospital violated the Civil Rights Act by discriminating against her because of her sexual orientation.

The district court dismissed the case.

In January 2016, Lambda Legal filed an appeal on Evans’ behalf. This past March, a three-judge panel of the Eleventh Circuit rejected Evans’ claim. Lambda Legal asked the whole court to rehear the case but that request was denied as well.
