appeal my case
It is possible to seek direct review by the Washington State Supreme Court, but they accept very few direct appeals. I have successfully obtained direct review several times, but again, it is quite rare. I agree with others responding here that you should contact an appellate lawyer immediately. Time is very short.See question
Only the Supreme Court can waive the appellate filing fees.See question
The denial occurred in Washington Superior Court - appeal would be to Division II - I would rather wait until after trial to appeal.
Unless there are Findings that there is no just reason for delay and a direction for entry of a final order or judgment under CR 54 (b), you can wait to appeal until a judgment or other final order is entered. Discovery orders generally are interlocutory, non final orders. You may lose your opportunity to effectively challenge the order though, if the appellate court does not find a prejudicial abuse of discretion.See question
