Tennesseans, in a slow trickle, have requested and gotten refunds from the state since the Tennessee Supreme Court struck down the so-called crack tax law in 2009. The state Department of Revenue has refunded $3.7 million to 161 people, but 2,772 people who paid the tax have not gotten any money back. "Most of them just don't know, and the state doesn't have any intention of letting them know, that they're eligible for a full refund," said Columbia attorney John Colley, who is leading a class-action lawsuit that would allow attorneys to identify and notify all people who paid the tax while it was still on the books.
