Lead Opinion
delivered the Opinion of the Court.
¶1 First, this ease requires us to determine whether a police officer’s testimony that a defendant was under the influence of meth-amphetaihine was lay or expert testimony. Because any error in admitting the officer’s testimony as'lay testimony was harmless given the otherwise overwhelming evidence, we decline to answer whether the trial court erred in admitting the testimony. Next, this case requires us to determine if Amendment 64 to the Colorado Constitution, which legalized possession of small amounts of marijuana, deprived the State of its power to continue to prosecute cases where there was a conviction for possession of less than one ounce of marijuana pending on direct appeal when the Amendment became effective. In light of our holding today in People v. Boyd,
I. Facts and Procedural History
¶2 In March 2010, defendant Brandi Jessica Russell and her husband brought their infant to a hospital with a broken femur. A doctor, worried that the child may have been abused, contacted ¾ social worker who then contacted Grand County Department of Social Services. A social worker interviewed Russell and, worried she was on drugs, obtained a court order for a drug test. The drug test indicated that Russell had used amphetamine, marijuana, and methamphetamine. When asked about the results, Russell admitted that she had used methamphetamine. The police obtained a warrant and searched Russell’s home, finding drug paraphernalia, marijuana, marijuana concentrate,
¶3 The State charged Russell with child abuse resulting in serious injury, possession of one gram or less of a schedule II controlled substance (methamphetamine), and possession of marijuana concentrate. In June 2011, a jury acquitted Russell of the child abuse charge but found her guilty of the marijuana concentrate and methamphetamine charges. The jury also convicted her of possession of less than one ounce of marijuana, a non-included petty offense that Russell requested. In August 2011, the trial court sentenced Russell to two concurrent 4-year terms of supervised probation, 192 hours of community service, and a suspended 90-day jail sentence.
¶4 Russell filed a timely notice of appeal in September 2011. Ultimately, she made two challenges. The first challenge was to a police officer's lay testimony offered at trial in which the officer testified to his belief that Russell was using methamphetamine based on his observations of her and his many contacts with others using methamphetamine. Russell argued this testimony required the officer to be vetted as an expert. The court of appeals disagreed with Russell. People v. Russell,
A.Any error in allowing the officer’s testimony as lay testimony was harmless.
¶5 Russell argues that it was error for the trial court to allow a police officer to testify, as a lay witness, to whether or not Russell was using methamphetamine based on the officer’s observations of Russell. This court reviews a trial court's rulings on evi-dentiary issues for an abuse of discretion. People v. Stewart,
¶6 Evidentiary errors do not require reversal if they ai’e harmless. People v. Summitt,
¶7 We decline to reach the issue of whether the officer’s testimony was improperly admitted as lay testimony because, in any event, the error was harmless. The evidence of Russell’s methamphetamine possession outside the officer’s testimony was overwhelming, including: (1) two doctors and two social workers had observed Russell and testified to her agitated state, repetitive movements, and tongue movements; (2) a doctor qualified as an expert in child abuse opined that Russell’s behavior was consistent with methamphetamine use; (3) Russell’s urine tested positive for methamphetamine; and (4) Russell admitted that she had used methamphetamine.
¶8 Because it is beyond a reasonable doubt that Russell would have been convicted of methamphetamine possession with or without the officer’s challenged testimony, we hold that any error in admitting that testimony as lay testimony was harmless. Therefore, we affirm the court of appeals on this issue.
B.Amendment 64 deprived the State of its power to continue to prosecute Russell.
¶9 This case presents an opportunity to resolve whether Amendment 64 deprived the State of its power to continue to prosecute cases where there was a conviction for possession of less than one ounce of marijuana pending on direct appeal when the Amendment became effective. Because resolving this requires us to interpret a constitutional amendment, our review is de novo. Danielson v. Dennis,
¶10 Similarly here, Russell was charged with possessing less than one ounce of marijuana under section 18-18-406(1), C.R.S. (2010),
III. Conclusion
¶11 We first conclude that because it is beyond a reasonable doubt that Russell would have been convicted of methamphetamine possession with or without the officer’s challenged testimony, we hold that any error in admitting that testimony as lay testimony was harmless. We next conclude that Amendment 64 deprived the State of the power to continue to prosecute cases where there was a nonfinal conviction for possession of less than one ounce of marijuana pending on direct appeal when the Amendment became effective. Accordingly, we affirm the judgment of the court of appeals on both issues.
Notes
. The amounts of marijuana and marijuana concentrate at issue in this case were both less than one ounce.
. Specifically, we granted certiorari to review the following issues:
1. Whether the court of appeals reversibly erred by affirming the trial court’s admission of testimony by a police officer—whowas not qualified as an expert witness— concerning the epidemiology of methamphetamine use and concluding that the petitioner's behavior was indicative of methamphetamine use.
2.Whether the court of appeals erred in holding Amendment 64 applies retroactively.
The second issue fundamentally asks us to address the effect of Amendment 64 on nonfinal convictions pending on direct appeal when the Amendment became effective. We do not find it necessary to address the effect of Amendment 64 on final convictions.
. After Amendment 64 became effective, Boyd timely filed her appeal. Boyd, ¶ 2.
. As relevant here, this statute was identical to section 18-18-406(1), C.R.S. (2011).
Concurrence in Part
concurring in part and dissenting in part.
¶12 I agree with the majority that any error in allowing the officer’s testimony as lay testimony was harmless, and thus join Part II.A of its opinion. Because I disagree with the majority’s holding that Amendment 64 is retroactive, I respectfully dissent from Part II.B of its opinion for the reasons set forth in my dissent in People v. Boyd,
I am authorized to state that JUSTICE COATS and JUSTICE HOOD join in this concurrence in part and dissent in part.
