The bakery refused to bake a wedding cake cake for lesbian couple Laurel and Rachel Bowman-Cryer in January 2013.
In April this year, a judge ruled that the bakery had discriminated against the couple and suggested damages of $135,000. Now, the Bureau of Labor and Industries has affirmed that amount, ordering Sweet Cakes to pay it.
Bakery owners Aaron and Melissa Klein said their refusal to bake for the lesbian couple was prompted by their religious beliefs regarding marriage.
The case has been cited in the national debate over religious freedom and discrimination against gays.
The couple intends to appeal the decision.
Last April crowdfunding site GoFundMe shut down the couple's campaign because it involved formal charges.
The Kleins will still receive the $109,000 donated to the fund before it was shut down.
Meanwhile, Samaritan’s Purse has established a fund to help people who face financial distress and are punished for their sincerely held religious beliefs, convictions, and conscience.
