In criminal cases, the Fourth Circuit defines a “plain error” as one that is obvious, detrimentally affects the rights of the defendant, and is so egregious as to implicate the “fairness, integrity, or public reputation of judicial proceedings. . .” United States v. Bellamy, 264 F.3d 448, 445 (4th Cir. 2001), cert. denied, 543 U.S. 1143 (2002). This very strong language makes it clear that plain error is not a term used by the Circuit to describe harmless or justifiable mistakes.
