The Metropolitan Washington Airports Authority scored a victory in federal court on Thursday with the dismissal of a lawsuit seeking to end the use of Dulles Toll Road revenue for the construction of Dulles Metrorail.

The suit was brought by two disgruntled Dulles Toll Road users, Virginia residents John Corr and John Grisby. Their lawyers argued that the tolls, imposed by the airports authority, constituted a tax. Because the board members of the airports authority are appointed – not elected – officials, the plaintiffs claimed “taxation without representation.”
