Conn. Code Evid. § 4-5
Evidence of Other Crimes, Wrongs
or Acts Generally Inadmissible
(a) General rule. Evidence of other crimes,
wrongs or acts of a person is inadmissible to prove
the bad character, propensity, or criminal tendencies of that person except as provided in subsection (b).
(b) When evidence of other sexual misconduct is admissible to prove propensity. Evidence of other sexual misconduct is admissible
in a criminal case to establish that the defendant
had a tendency or a propensity to engage in aberrant and compulsive sexual misconduct if: (1) the
case involves aberrant and compulsive sexual
misconduct; (2) the trial court finds that the evi -
dence is relevant to a charged offense in that the
other sexual misconduct is not too remote in time,
was allegedly committed upon a person similar
to the alleged victim, and was otherwise similar
in nature and circumstances to the aberrant and
compulsive sexual misconduct at issue in the
case; and (3) the trial court finds that the probative
value of the evidence outweighs its prejudicial
effect.
(c) When evidence of other crimes, wrongs
or acts is admissible. Evidence of other crimes,
wrongs or acts of a person is admissible for pur -
poses other than those specified in subsection (a),
such as to prove intent, identity, malice, motive,
common plan or scheme, absence of mistake or
accident, knowledge, a system of criminal activity,
or an element of the crime, or to corroborate crucial prosecution testimony.
(d) Specific instances of conduct when character in issue. In cases in which character or a
trait of character of a person in relation to a
charge, claim or defense is in issue, proof shall
be made by evidence of specific instances of the
person’s conduct.
History
(Amended June 20, 2011, to take effect Jan. 1, 2012.) COMMENTARY (a) Evidence of other crimes, wrongs or acts gener- ally inadmissible. Subsection (a) is consistent with Connecticut common law. E.g., State v. Santiago, 224 Conn. 325, 338, 618 A.2d 32 (1992); State v. Ibraimov, 187 Conn. 348, 352, 446 A.2d 382 (1982). Other crimes, wrongs or acts evidence may be admis- sible for other purposes as specified in subsections (b) and (c) and Section 4-4 (a) (4). Cf. State v. Hedge, 297 Conn. 621, 650–52, 1 A.3d 1051 (2010); see Section 4-4 (a) (4), commentary. Although the issue typically arises in the context of a criminal proceeding; see State v. McCarthy, 179 Conn. 1, 22, 425 A.2d 924 (1979); subsection (a)’s exclusion applies in both criminal and civil cases. See, e.g., Russell v. Dean Witter Reynolds, Inc. , 200 Conn. 172, 191–92, 510 A.2d 972 (1986). (b) When evidence of other sexual misconduct is admis- sible to prove propensity. Subsection (a) specifically prohibits the use of other crimes, wrongs or acts evidence to prove a person’s propensity to engage in the misconduct with which the defendant has been charged. However, the court may admit evidence of a defend- ant’s uncharged sexual misconduct to prove that the defendant had a tendency or a propensity to engage in aberrant and compulsive sexual behavior. State v. Snelgrove, 288 Conn. 742, 759–61, 954 A.2d 165 (2008); State v. DeJesus, 288 Conn. 418, 470–74, 953 A.2d 45 (2008); see State v. Johnson, 289 Conn. 437, 452–55, 958 A.2d 713 (2008), overruled in part on other grounds by State v. Payne, 303 Conn. 538, 34 A.3d 370 (2012); see also State v. Smith, 313 Conn. 325, 337–38, 96 A.3d 1238 (2014) (evidence of uncharged sexual misconduct that involved choking victim while she resisted sexual attack held sufficiently similar to be admissible); State v. George A., 308 Conn. 274, 298–300, 63 A.3d 918 (2013) (evidence of uncharged sexual misconduct committed by defendant against minor victim’s mother held admissible); but see State v. Gupta, 297 Conn. 211, 224–34, 998 A.2d 1085 (2010) (evidence that defendant physician had fondled other patients too dissimilar to be admissible). Although DeJesus involved a sexual assault charge, later, the Supreme Court, in Snelgrove, made it clear that the DeJesus propensity rule is not limited to cases in which the defendant is charged with a sex offense. In Snelgrove, the court stated: ‘‘We conclude that this rationale for the exception to the rule barring propen- sity evidence applies whenever the evidence establishes that both the prior misconduct and the offense with which the defendant is charged were driven by an aberrant sexual com- pulsion, regardless of whether the prior misconduct or the conduct at issue resulted in sexual offense charges.’’ State v. Snelgrove, supra, 760. The admission of the evidence of a defendant’s uncharged sexual misconduct to prove that the defendant had a tendency or a propensity to engage in aber- rant and compulsive sexual behavior should be accompanied by an appropriate cautionary instruction limiting the purpose for which it may properly be used. State v. George A., supra, 294–95; State v. DeJesus, supra, 474. (c) When evidence of other crimes, wrongs or acts is admissible. Subsection (a) specifically prohibits the use of other crimes, wrongs or acts evidence to prove a person’s bad character or criminal tendencies. Subsection (c) however, authorizes the court, in its discretion, to admit other crimes, wrongs or acts evidence for other purposes, such as to prove: (1) intent; e.g., State v. Lizzi, 199 Conn. 462, 468–69, 508 A.2d 16 (1986); (2) identity; e.g., State v. Pollitt, 205 Conn. 61, 69, 530 A.2d 155 (1987); (3) malice; e.g., State v. Barlow, 177 Conn. 391, 393, 418 A.2d 46 (1979); (4) motive; e.g., State v. James, 211 Conn. 555, 578, 560 A.2d 426 (1989); (5) a common plan or scheme; e.g., State v. Randolph, 284 Conn. 328, 356, 933 A.2d 1158 (2007); State v. Morowitz, 200 Conn. 440, 442–44, 512 A.2d 175 (1986); (6) absence of mistake or accident; e.g., State v. Tucker, 181 Conn. 406, 415–16, 435 A.2d 986 (1980); (7) knowledge; e.g., State v. Fredericks, 149 Conn. 121, 124, 176 A.2d 581 (1961); (8) a system of criminal activity; e.g., State v. Vessichio, 197 Conn. 644, 664–65, 500 A.2d 1311 (1985), cert. denied, 475 U.S. 1122, 106 S. Ct. 1642, 90 L. Ed. 2d 187 (1986); (9) an element of the crime charged; see, e.g., State v. Chyung, 325 Conn. 236, 263–64, 157 A.3d 628 (2017) (prior misconduct evidence held admissible to prove intent to kill); see also State v. Torres, 57 Conn. App. 614, 622–23, 749 A.2d 1210, cert. denied, 253 Conn. 927, 754 A.2d 799 (2000); (10) to corroborate crucial prosecution testimony; e.g., State v. Mooney, 218 Conn. 85, 126–27, 588 A.2d 145, cert. denied, 502 U.S. 919, 112 S. Ct. 330, 116 L. Ed. 2d 270 (1991); or (11) third-party culpability by defendant’s proffer of third party’s other crimes, wrongs or acts; State v. Hedge, supra, 297 Conn. 650–52. Admissibility of other crimes, wrongs or acts evidence is contingent on satisfying the relevancy standards and balanc - ing test set forth in Sections 4-1 and 4-3, respectively. For other crimes, wrongs or acts evidence to be admissible, the court must determine that the evidence is probative of one or more of the enumerated purposes for which it is offered and that its probative value outweighs its prejudicial effect. E.g., State v. Figueroa, 235 Conn. 145, 162, 665 A.2d 63 (1995); State v. Cooper, 227 Conn. 417, 425–28, 630 A.2d 1043 (1993). Although the Supreme Court has established no abso- lute time limit that would bar admissibility of uncharged miscon- duct, it has suggested that remote prior misconduct must bear a substantial similarity to conduct at issue and be of an aberrant or compulsive nature to be admissible. See State v. Chyung, supra, 325 Conn. 264, 266 n.27 (fourteen year gap between incidents of misconduct did not render prior misconduct irrele- vant ‘‘given the strong similarities between the two incidents and the strongly aberrational nature of the defendant’s con - duct’’); cf. State v. Snelgrove, supra, 288 Conn. 761 (noting that, ‘‘ordinarily, a gap of fourteen years would raise serious questions as to whether the prior misconduct was too remote in time’’). Concerns about remoteness are lessened if the defendant was incarcerated for a substantial period during the gap. See State v. Snelgrove, supra, 761–62; State v. Murrell, 7 Conn. App. 75, 89, 507 A.2d 1033 (1986). The purposes enumerated in subsection (c) for which other crimes, wrongs or acts evidence may be admitted are intended to be illustrative rather than exhaustive. Neither subsection (a) nor subsection (c) precludes a court from recognizing other appropriate purposes for which other crimes, wrongs or acts evidence may be admitted, provided the evidence is not intro- duced to prove a person’s bad character or criminal tenden- cies, and the probative value of its admission is not outweighed by any of the Section 4-3 balancing factors. (d) Specific instances of conduct when character in issue. Subsection (d) finds support in Connecticut case law. See State v. Miranda, 176 Conn. 107, 112, 405 A.2d 622 (1978); Norton v. Warner, 9 Conn. 172, 174 (1832).
