12/14 Update: The case has been heard and the judge has promised a decision this month.
Judge Andrea Darvas of King County Superior Court will hear a challenge today on the $15-an-hour minimum wage just approved by voters in the small town of SeaTac, Wash.
Supporters of the measure, which won with a margin of fewer than 100 votes, have already vowed to appeal to the state's highest court if the judge nixes the measure.
The initiative, set to go into effect on Jan. 1, will raise the minimum wage to $15 for most workers in the city, but it exempts airlines and small businesses with fewer than 10 employees.
Alaska Airlines, though exempt, is leading the challenge, saying that higher costs at airport facilities will drive away passengers. The Washington Restaurant Association has joined the challenge.
Opponents content the law is too vaguely written and that the city of SeaTac has no legal authority over SeaTac Airport, which is operated by the Port of Seattle.
