If you believe a court judgement was obtained through false affidavits and claims, and you've since found solid evidence, you have legal recourse. While a perjury case can't be proven without existing evidence, you can file an appeal with your new proofs. The appellate court may issue a remand order to re-examine the false claims. You might also be able to seek a review of the original judgement based on the newly discovered evidence. Perjury proceedings would typically follow the outcome of these review or appeal processes.
