Brian P. Crocker appeals from orders of the district court 1 (1) dismissing his 42 U.S.C. § 1983 action against John Wetlaufer and Norine Canney, and (2) denying his Federal Rule of Civil Procedure 52(b) post-judgment motion to amend or enlarge the district court’s findings. The district court’s orders were decided on grounds that Crocker received a full and fair opportunity to litigate in garnishment proceedings in Iowa state court in 2002, and res judicata bars issues that were or could have been asserted in those proceedings, including those being asserted in the case at bar. We note that, in a 2003 state-court action that Crocker brought against Canney, the Iowa courts precluded him from relitigating similar issues on the ground that they could have been asserted in the prior garnishment proceedings. We therefore agree with the district court’s reasoning and conclusions in the present case. See Allen v. McCurry, 449 U.S. 90, 96,104, 101 S.Ct. 411, 66 L.Ed.2d 308 (1980) (federal courts afford state-court judgments preclusive effect in § 1983 cases whenever the state courts themselves would do so, provided the adjudicating court acted within its proper jurisdiction and the parties had a full and fair opportunity to litigate the federal claim). The orders of the district court are affirmed. See 8th Cir. R. 47B.
