Re: Can Small Claims Court Rule to Reverse a Private Party Sale
from what I have found, Cal SCC allows for injunctive relief.
based on what you have stated, you have not shown where you would have a right to demand the rescission of the sale with the possible exception of the ownership issue. That is pretty simple though; if the seller did not have the authority to sell the vehicle to you, there is no option but to rescind the deal. If he had authority to sell it to you, it's yours.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
