(Salem, OR) -- A pair of Gresham bakers will have to pay for refusing to serve a lesbian couple. The Oregon Court of Appeals upheld a decision to have Melissa and Aaron Klein pay a lesbian couple 135-thousand dollars for refusing to bake them a cake. A judge ruled that Sweetcakes by Melissa violated a law that prohibits businesses from discriminating based on sexual orientation. The Kleins argued four years ago that baking a gay wedding cake went against their Christian beliefs. They closed their business last year.
