On May 5, 2009, the FAA dismissed a Part 16 complaint filed against Firm client, the Metropolitan Nashville Airport Authority. The owner of a shoe shine concession at the Nashville International Airport alleged that the Airport Authority had discriminated against it in violation of 49 C.F.R. Part 23. Factual allegations primarily concerned the complainant's sublease with a master concessionaire. The FAA correctly determined that the complainant had failed to establish a prima facie claim of discrimination.
