In this civil suit alleging unfair debt collection practices, Stuart Juarez appeals from the district court’s 1 order (1) denying him permission to file a second amended complaint, and (2) granting summary judgment in favor of Litow Law Office, P.C. After careful review, we affirm. See Popoalii v. Corr. Med. Servs., 512 F.3d 488, 497 (8th Cir. 2008) (concluding the district court did not abuse its discretion in denying a late-filed motion to amend where the proposed amended complaint contained new theories of recovery); Johnson v. Blaukat, 453 F.3d 1108, 1112 (8th Cir. 2006) (reviewing a grant of summary judgment de novo). See 8th Cir. R. 47B.
