I am guessing all your questions where rhetorical?
Did you have an attorney defending you and moving your case forward in your interests?
READ THIS BEFORE CALLING OR EMAILING ME: I am licensed to practice before the state and federal courts in Virginia. We have not established an attorney-client relationship unless we have a signed representation agreement and you have paid me. I am providing educational instruction only--not legal advice. You should speak with an attorney to whom you have provided all the facts, before you take steps that may impact your legal rights. I am not obligated to answer subsequent emails or phone calls unless you have hired me. I wish you the best of luck with your situation.
Demonstrating a fraud upon the court can be a basis to set aside an order or judgment (and judges get *very* angry at those who try to pull one over on them).
You need to be able to prove this, though, and your chance without an attorney is similar to the proverbial ice cube. And if you find an attorney to take this on a pure contingecny, you're probably dealing with a fool.
