JACKSON, Miss. (AP) — A lesbian who sued her school district in 2010 after she was left out of the high school yearbook for wearing a tuxedo is demanding the Mississippi Agriculture and Forestry Museum permit a commitment ceremony for her and her partner.

The Southern Poverty Law Center sent a letter to the museum on Thursday on behalf of Ceara Sturgis, 20, and threatened to sue if the facility doesn’t allow Sturgis and her partner, 19-year-old Emily Key, to hold the ceremony there on Aug. 11.
