(FORTUNE Magazine) – GAINESVILLE, FLA. -- Joseph Sexton and Beth-Anne Thye got married in August 1987 . . . The University of Florida law students . . . are ((now)) making a legal challenge to the State Department of Highway Safety and Motor Vehicles, ((which is)) not allowing him to combine his surname with hers on his driver's license. ''Basically what my wife could do for free, I would have to go out and hire an attorney to do,'' he said, ''and that's what struck me as wrong with the whole system.'' That problem spurred them to . . . legally ((challenge)) that * policy, claiming it is a form of sex discrimination . . . The Thye Sextons, as they call their union, . . . are set for a hearing before the state division of Administrative Hearings. -- From an AP dispatch.
