Debt collector files lawsuit against debtor on behalf of creditor in appropriate court. While the lawsuit pends, the Seventh Circuit decides a different court is appropriate for such suits and makes the change retroactive. The debtor then sues the creditor and debt collector for filing in the wrong venue, settling with the creditor but winning $200 in damages plus $70k in attorney’s fees from the debt collector. Seventh Circuit: Reversed. The settlement moots the debtor’s claim against the debt collector.
