A federal court has dismissed the appeal of a lawsuit challenging a transgender woman's acceptance into a sorority at the University of Wyoming. The three-judge U.S. 10th Circuit Court of Appeals in Denver ruled Wednesday the case wasn't appealable because it could be refiled in a lower court. Six members of the Kappa Kappa Gamma sorority chapter in Laramie, Wyoming, sued to challenge Artemis Langford's admittance into the organization.
