In an ideal world where things are done fairly and logically, yes.
I am anxious to speak with an attorney but I am concerned with valid reasoning. In a civil case, the burden of proof will be on ME as the person who sold and shipped the bag, to PROVE the bag I had authenticated and a receipt, photos, etc of, is the one I put in a box and SENT to her.
The "evidence" being the bag, is "gone" since the buyer will say she destroyed my "fake" bag per paypal policy.
Scary but a very valid concern.
You need to find out who told the Buyer she could destroy the bag. You may be able to make out a claim for spoilation of evidence - the bag was deliberately destroyed, thus depriving you of the ability to prove it was authentic. Spoilation is a separate tort in Calif. but I haven't read up on all of the elements of it in quite a long time, I must admit!
