More information on which court, the exact nature of the request/complaint and anything else I can dig up as it makes it to me.
Update (11:20): The court filing is with Multnomah County Court for the State of Oregon, according to initial sources.
Update (11:42): A hearing on the matter is scheduled for tomorrow at 1:30 PM at the Multnomah County Courthouse.
Update (4:08): Janie Har at the O's political blog has more detail on the specifics of the filing:
The complaint, filed by attorney Jeff Merrick in Multnomah County Circuit Court, alleges the political committee and consultant Chuck Adams are responsible for “a false statement of material fact” in violation of state campaign finance law.
I actually had this information earlier today, but didn't quite understand what I was reading. This complaint would fall under ORS 260.532.
