Does the redesignation of a felony as a misdemeanor require the expungement of DNA samples previously collected as a result of the adjudication or prior adjudication?

language in isolation; instead, we construe it "in context, keeping in mind the statutes' nature and obvious purposes," and we "harmonize the various parts of the enactments by considering them in the context of the statutory framework as a whole." (People v. Cole (2006) 38 Cal.4th 964, 975.) "If the statutory language is unambiguous, then its plain meaning controls. If, however, the language supports more than one reasonable construction, then we may look to extrinsic aids, including the ostensible objects to be achieved and the legislative history." (Ibid.)

Proposition 47, enacted by the voters in November 2014, reduced certain drug and theft offenses to misdemeanors unless the offenses were committed by otherwise ineligible defendants. (People v. Rivera (2015) 233 Cal.App.4th 1085, 1089, 1091.) Section 1170.18, the resentencing provision added by Proposition 47, provides that a person who was found to have committed a felony, yet "who would have been guilty of a misdemeanor under [Proposition 47]" had it been in effect at the time of the offense, may request that the offense be designated a misdemeanor. ( 1170.18, subds. (a), (f).) Neither section 1170.18 nor any other provision of Proposition 47 addresses whether the redesignation of a felony as a misdemeanor requires the expungement of DNA samples previously collected as a result of a felony conviction or adjudication. Section 1170.18 only states, in subdivision (k), that an offense designated a misdemeanor pursuant to the statute "shall be considered a misdemeanor for all purposes" except as to restrictions on the person's ability to own or possess a firearm.² ( 1170.18, subd. (k).)
