Rule 404(b): The Requirement of Similarity

Published for NC Criminal Law on May 13, 2013.

Even when Rule 404(b) evidence is relevant to an issue other than propensity or disposition, admissibility is “constrained by the requirements of similarity and temporal proximity.” State v. Beckelheimer, __ N.C. __, 726 S.E.2d 156, 159 (2012) (quoting State v. Al-Bayyinah, 356 N.C. 150, 154 (2002)). In this, my fourth post on Rule 404(b) evidence, I’ll explore the requirement of similarity. As a general rule, 404(b) evidence must be sufficiently similar to the act in question. The evidence is sufficiently similar if there are unusual facts present in both incidents. Beckelheimer, 726 S.E.2d at 159. However, the similarities need not “rise to the level of the unique and bizarre.” Id. (quotation omitted). Nor must the incidents be identical. Id. at 160. As the North Carolina Supreme Court has stated: “near identical circumstances are not required; rather, the incidents need only share some unusual facts that go to a purpose other than propensity.” Id. (quotation and citation omitted); see also State v. Khouri, __ N.C. App. __, 716 S.E.2d 1, 8 (2011) (in a child sex case, rejecting the defendant’s argument that the defendant’s sex acts with another child were different from those charged because one occurred in private and the other occurred in public). By the same token, for most 404(b) purposes, some degree of similarity is required; when the requisite similarity is lacking, the evidence is inadmissible. See State v. Davis, __ N.C. App. __, 731 S.E.2d 236, 239-42 (2012) (in a child sex case in which the defendant was [...]
