Under the doctrine of res judicata, or claim preclusion, a valid final judgment bars future actions between the same parties on the same cause of action, as well as all other claims arising out of the same transaction or series of transactions, even if based upon different theories or if seeking a different remedy.
Here, the Supreme Court incorrectly determined that this action constituted an improper collateral attack on the order and judgment of foreclosure and sale.
