United States v. Estrada

¶5PER CURIAM.

¶6Antonio Estrada was convicted by a jury of distributing cocaine in violation of 21 U.S.C. § 841(a)(1). He appeals one of the district court’s evidentiary rulings. We affirm.

¶7Estrada negotiated a sale of cocaine to Faustino Juan Oliver. During their discussions the two spoke on the phone and in person several times. Unbeknownst to' Estrada, Oliver was a confidential informant (Cl) working with law enforcement authorities and these conversations were recorded. At trial the government introduced these recorded conversations. Oliver testified as to his understanding of statements made during the tape recorded conversations he had with Estrada and interpreted the coded conversations for the jury. Estrada argues that Oliver provided impermissible lay testimony in violation of Federal Rule of Evidence 701. We review a district court’s evi-dentiary rulings for an abuse of discretion. See, e.g., United States v. Kozinski, 16 F.3d *773795, 809 (7th Cir.1994); United States v. Fulford, 980 F.2d 1110, 1114 (7th Cir.1992).

Federal Rule of Evidence 701 provides: If the witness is not testifying as an expert, the witness’ testimony in the form of opinions or inferences is limited to those opinions or inferences which are (a) rationally based on the perception of the witness and (b) helpful to a clear understanding of the witness’ testimony or the determination of a fact in issue.

¶8F.R.E. 701. The first requirement, that Oliver’s testimony is rationally based on his own perceptions, has been met here. See United States v. Allen, 10 F.3d 405, 414 (7th Cir.1993). Oliver was a participant in the conversations "with Estrada and testified as to his understanding of their communications. See Kozinski, 16 F.3d at 809 (witness had personal knowledge of his own mental processes and was competent to testify regarding them). Rule 701’s second requirement is that the testimony be helpful to the jury’s understanding of the issues at trial. See Allen, 10 F.3d at 414. The conversations between Oliver and Estrada included code words for the negotiation of cocaine.1See United States v. Hughes, 970 F.2d 227, 237 (7th Cir.1992) (individuals involved in narcotics transactions tend to speak in coded terms); United States v. Zanin, 831 F.2d 740, 744 (7th Cir.1987) (“conversations regarding drug transactions are rarely clear”). Oliver’s testimony assisted the jury’s understanding of the content of the recorded conversations. The requirements of Rule 701 are satisfied. See also United States v. Simas, 937 F.2d 459, 465 (9th Cir.1991) (testimony allowed as to meaning of vague and ambiguous statements); United States v. DePeri, 778 F.2d 963, 977 (3d Cir.1985) (language in taped conversation “composed with unfinished sentences and punctuated with ambiguous references” ... “as if he were using code”). Therefore the district court’s judgment is AFFIRMED.2
