What is the standard for determining procedural errors in a civil case?

Because Wated did not raise any of his procedural objections to the district court, we review only for plain error, see United States v. Villafuerte, 502 F.3d 204, 207 (2d Cir. 2007), a standard that requires him to show (1) error, (2) that is clear or obvious, (3) affecting substantial rights, and (4) calling into question the fairness, integrity, or public reputation of judicial proceedings, see United States v. Marcus, 560 U.S. 258, 262 (2010). We identify no procedural errormuch less plain errorin this case.
