Arguing Wednesday in a legal appeal against it, the Kappa Kappa Gamma sorority asserted that inducting transgender members is reasonable, that it’s the norm among nationally recognized sororities and that it’s supported by the dictionary.

The appeal stems from a 2023 lawsuit in which six members of the University of Wyoming chapter of the sorority sued Kappa Kappa Gamma over the induction of transgender member Artemis Langford. The women lost that lawsuit in August 2023, when U.S. District Court Judge Alan B. Johnson ruled that it’s not the court’s place to define the word “woman” for a private organization.

The six members challenged Johnson’s ruling days later in the 10th Circuit Court of Appeals.

Kappa Kappa Gamma filed its own argument in the appeals court Wednesday, reiterating case law that says a private organization has a First Amendment right to dictate the terms of its membership.
