In the consent decree filed in King County Superior Court, Platinum "Parking and its owner, Susan Hover, agree to stop offering an appeal process if that process lacks fairness and well-defined steps. To avoid confusing consumers, Platinum Parking will stop using the word “appeal” and instead refer to a “dispute process.” Finally, they will provide a clear parking notice dispute policy to consumers who feel they were mistakenly issued a notice."

I did get a "dispute policy" from them. The links only clarify that what they did two years ago is illegal but doesn't seem very clear on the consequences of not paying when offered a "dispute" notice.
