A Gulf War veteran and his wife say they've been unfairly placed on a federal list that limits their commercial flight access and threatens his job as a commercial pilot. To fight back, the couple, who are Muslim, filed a lawsuit today against a host of U.S. government agencies. "We don't know why they're on the list. They don't know why they're on the list. The government won't tell us why they're on the list," said Amy Foerster, an attorney with Saul Ewing, who is providing pro bono counsel and working with the American Civil Liberties Union of Pennsylvania and the Schuylkill County couple on the case, which was filed in U.S. district court. The suit filed against the U.S. departments of Homeland Security and Justice and the FBI, among others, is "unique" because Erich Scherfen, a New Jersey native who converted to Islam in the mid-1990s, is a commercial airline pilot whose flight privileges were revoked in April, said Witold Walczak, the legal director of the state ACLU chapter. On Sept. 1, Scherfen will be terminated by his employer, Colgan Air, despite the airline's cooperation. "My livelihood depends on getting off this list," Scherfen said. What list he is on and which government entity maintains it is unclear, Walczak said. The federal government has declined to acknowledge flight restrictions placed on the pilot. But Scherfen says he and his wife, Pakistan-born Rubina Tareen, have been detained for hours on several occasions in airports and even border crossings and been told by airport ticket agents and security personnel that they're on a "terrorist watch list." In order for Scherfen to keep his job, Walczak additionally requested an emergency injunction, a move that could provide results as early as today but would only be a temporary fix. "We wouldn't file a suit we didn't think we could win," Walczak said.
