Re: Speeding in Washington
Contact the Clerk of the Court. There is probably a standard form they will give you for filing an appeal. The cost is a couple hundred dollars, which you DO NOT get back, even if you win.
Plus, you have to realize that an appeal is NOT a new trial. It is an appeal "on the record". You must show that the judge made an error -- in your case that he SHOULD have granted a continuance.
If you win on appeal, the Superior Court will simply order a new hearing before the same judge (who will be instructed to grant the continuance so the you can bring in a handwriting expert). But, you also need to understand, that that judge may STILL rule against you, unless the expert can unequivocally state that these were NOT signed by the same person (and, personally, they look like one was signed in a hurry (on the left) while the other was more leisurely -- but I'm no expert!).
Wish I had better news,
Where am I going? And why am I in this handbasket?
