Blatt, Hasenmiller, Leibsker & Moore, LLC v. Oliva

(1) Whether good faith reliance on controlling circuit precedent, prior to any retroactive change in that law, is an unintentional "bona fide error" and a procedure "reasonably adapted to avoid error" within the meaning of the "bona fide error" defense in the Fair Debt Collection Practices Act, 15 U.S.C. § 1692k(c); and (2) whether the due process clause prohibits punishment for conduct that was lawful when committed, but later prohibited by a retroactive change of law.
