State v. Lassiter, 2016 NMCA 078

In 2009 Lassiter pleaded guilty to methamphetamine trafficking and received a conditional discharge under NMSA 1978 § 31-20-13(A): she was placed on probation and, after successful completion, the charge was dismissed without an adjudication of guilt.
In 2013 Lassiter pleaded no contest to a separate trafficking charge. The State sought enhancement to first-degree trafficking as a "second or subsequent offense" under NMSA 1978 § 30-31-20(B)(2).
The district court refused to treat the 2009 conditional discharge as a prior "offense" for enhancement and sentenced Lassiter as a first-time offender (second-degree felony).
The State appealed, arguing that the 2009 conduct underlying the conditional discharge qualified as a prior "offense" and thus required first-degree enhancement.
The Court of Appeals reviewed statutory interpretation de novo and examined the meaning of "offense" in § 30-31-20 and the interaction with the conditional discharge statute.
The court concluded § 30-31-20 is ambiguous as to whether prior conditional discharges may be used for enhancement and applied the rule of lenity, holding the conditional discharge could not be used to enhance Lassiter’s sentence.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether a prior conditional discharge (no adjudication of guilt) counts as a prior "offense" under § 30-31-20 for sentence enhancement	The term "offense" means the underlying illegal act; the 2009 conditional discharge should count as a prior offense and trigger first-degree enhancement	A conditional discharge results in no adjudication or conviction; because the earlier charge was dismissed without adjudication, it cannot be used as a prior offense for enhancement	The term "offense" in § 30-31-20 is ambiguous; applying lenity, a prior conditional discharge cannot be used to enhance the trafficking sentence
