The owners of a bakery in Gresham, Oregon, are refusing to pay $135,000 in state-ordered damages after denying services to a same-sex couple.

Melissa and Aaron Klein, the owners of Sweet Cakes by Melissa, cited their religious beliefs when they refused to bake a wedding cake for Laurel and Rachel Bowman-Cryer more than two years ago.

Labor Commissioner Brad Avakian awarded the damages in July for emotional suffering, saying the owners violated the women's civil rights by discriminating on the basis of their sexual orientation.

The Kleins have filed an appeal of the ruling and are defying the order to pay. They're claiming financial hardship, although crowdfunding efforts have brought in over $500,000 on their behalf, The Oregonian reported.

The couple closed their store, east of Portland, in 2013 and operate their business from home.

"It's difficult to understand the Kleins' unwillingness to pay the debt when they have, very publicly, raised nearly a half million dollars," labor bureau spokesman Charlie Burr told The Oregonian in an email Wednesday. "They are entitled to a full and fair review of the case, but do not have the right to disregard a legally binding order."

A lawyer for the Kleins, Anna Harmon, told The Oregonian she couldn't comment on her clients' actions, citing the pending litigation.

A 2007 Oregon law protects the rights of gay, lesbian, bisexual and transgender people in employment, housing and public accommodations. It provides an exemption for religious organizations, but the agency ruled that exemption does not allow private businesses to discriminate against potential customers.
