These guys being the Washington Farm Bureau, the Washington Restaurant Association and the Washington Retail Association:

A coalition of business groups sued the state last month over the decision to raise the minimum wage. The groups argue that the minimum wage can't be increased in 2011 because this year's Consumer Price Index does not reflect a net increase in the cost of living since 2008. A voter initiative tied the state's minimum wage to the index.

Stay tuned. They're taking the minimum wage to court today at 11 a.m. in Kittitas County.
