A neighbor, Rebecca Earnshaw, challenged Atlanta’s approval of a setback variance for a carport already built beside her Grant Park property. The superior court dismissed her petition for lack of standing, although the City and Urban Design Commission had not raised standing before the Commission. The Court of Appeals classified the variance decision as quasi-judicial, held that standing could be waived, and found the City had waived the issue by not raising it at the administrative hearing. It reversed dismissal on that ground and remanded for the superior court to consider the City’s separate, unresolved basis for dismissal.
