A Kittitas County judge is set to hear arguments on a lawsuit over the state's decision to raise the minimum wage by 12 cents to $8.67 on Jan. 1.
It is uncertain whether the judge will make a ruling in the case after Wednesday's 11 a.m. hearing.
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.
The coalition opposed to the increase includes the Washington Farm Bureau, the Washington Restaurant Association and the Washington Retail Association.
