ZINTER, Justice.
[¶ 1.] Nicole Mundy-Geidd was convicted of driving under the influence of
[¶ 2.] In 2013, Mundy-Geidd was arrested and charged with DUI, in violation of SDCL 32-23-1. The magistrate court denied Mundy-Geidd's pre-and post-trial motions to dismiss, which were predicated on now repealed SDCL 34-20A-93. Following her conviction after a magistrate court trial, the circuit court affirmed.
[¶ 3.] On appeal, Mundy-Geidd argues that from 2012 to 2014, SDCL 34-20A-93 prohibited the enforcement of SDCL 32-23-1. Mundy-Geidd points out that before its repeal in 2014, SDCL 34-20A-93 prohibited the State from enforcing laws that included "drinking, drunkenness, or being found in an intoxicated condition as one of the elements of the offense."
[¶ 4.] The State argues that the 2012 Legislature, in repealing SDCL 34-20A-95, did not intend to prohibit the enforcement of SDCL 32-23-1. The State points out that SDCL 34-20A-93 and SDCL 34-20A-95 were passed in 1974 as a part of the Uniform Alcoholism and Intoxication Treatment Act. See 1974 S.D. Sess. Laws ch. 240 ("An Act enacting the uniform alcoholism and intoxication treatment act, and to amend SDCL 27-8-14 and 35-5-21.3 and to repeal SDCL 22-13-4, 27-3-18, 27-3-20, 27-3-21, 27-3-22, 27-8-3.1, and 27-8-12, all relating to alcoholism."). The State also points out that the purpose of the 1974 Act was to decriminalize alcoholism
[¶ 5.] The parties' arguments require us to engage in statutory interpretation. The purpose of statutory interpretation is to discover legislative intent. Bostick v. Weber, 2005 S.D. 12, ¶ 7, 692 N.W.2d 517, 519 (citing State v. Myrl & Roy's Paving, Inc., 2004 S.D. 98, ¶ 6, 686 N.W.2d 651, 653).
[¶ 6.] Mundy-Geidd argues that in ascertaining legislative intent, we are precluded from looking beyond SDCL 34-20A-94 (repealed 2014). SDCL 34-20A-94 was enacted as a part of the 1974 Act. See 1974 S.D. Sess. Laws ch. 240, § 16(b). At the time of Mundy-Geidd's offense, SDCL 34-20A-94 prohibited the State and its political subdivisions from interpreting or applying a law of general application to circumvent SDCL 34-20A-93.
[¶ 7.] In interpreting the 1974 and 2012 Acts, we must examine more than their text because there is ambiguity,
[¶ 8.] The titles, history, and purposes of the 1974 and 2012 Acts reflect that the 2012 Legislature did not intend to end the enforcement of the DUI statute. As previously noted, SDCL 34-20A-93 was enacted by the 1974 Legislature to decriminalize public intoxication and offer individuals treatment for alcoholism. 1974 S.D. Sess. Laws ch. 240, § 1. Although the 1974 Act repealed certain alcohol-related statutes and criminal offenses, SDCL 32-23-1 was not included. 1974 S.D. Sess. Laws ch. 240, § 20. Further, the 2012 Act repealing SDCL 34-20A-95 was enacted "to repeal certain outdated or unnecessary statutes related to the Division of Behavioral Health within the Department of Social Services." 2012 S.D. Sess. Laws ch. 150. SDCL 32-23-1 is not such a statute. Indeed, the 2012 Act did not repeal or prohibit the enforcement of any criminal statute. 2012 S.D. Sess. Laws ch. 150. We see nothing in the history or purpose of these Acts suggesting that the 2012 Legislature intended to end the enforcement of SDCL 32-23-1.
[¶ 9.] Other contemporaneous legislation confirms our conclusion. Indeed, although the 2012 Legislature repealed SDCL 34-20A-95, it simultaneously revised a criminal penalty statute (SDCL 22-6-5.2) to expressly authorize enhanced penalties for violating SDCL 32-23-1. 2012 S.D. Sess. Laws ch. 119. The 2012 Legislature also amended rather than repealed SDCL 42-8-45, an analogous statute that prohibited boating while "under the influence" of alcohol. 2012 S.D. Sess. Laws ch. 208, § 1. And in 2013, the Legislature reaffirmed that SDCL 32-23-1 remained enforceable. That Legislature amended SDCL 32-23-4.1 and SDCL 32-23-4.6,
[¶ 10.] We also observe that Mundy-Geidd's interpretation of SDCL 34-20A-93 and SDCL 34-20A-95 would repeal SDCL 32-23-1 by implication. "[R]epeal by implication is strongly disfavored." Faircloth v. Raven Indus., Inc., 2000 S.D. 158, ¶ 10, 620 N.W.2d 198, 202 (citing Morton v. Mancari et al., 417 U.S. 535, 549, 94 S.Ct. 2474, 2482, 41 L.Ed.2d 290, 300 (1974)). "Judges should refrain from negating a legislative act unless it is demanded by manifest necessity." Id. (citing Karlen v. Janklow, 339 N.W.2d 322, 323 (S.D.1983)). "Before judicially implying a repeal, the Legislature's intent to do so must be apparent." Id. (citing Posadas v. Nat'l City Bank of N.Y., 296 U.S. 497, 504, 56 S.Ct. 349, 352, 80 L.Ed. 351, 355 (1936)). Here, the Legislature's intent to repeal SDCL 32-23-1 is not manifest or apparent. On the contrary, the 2012 Act specifically repealed 47 statutes, but SDCL 32-23-1 was not included. 2012 S.D. Sess. Laws ch. 150, §§ 1-47.
[¶ 11.] We finally observe that Mundy-Geidd's interpretation produces absurd and unreasonable results. Under Mundy-Geidd's interpretation, numerous public safety statutes involving alcohol would have been repealed by implication. See, e.g., SDCL 22-16-41 (prohibiting vehicular homicide while "under the influence of alcohol... in a manner and to a degree prohibited by" SDCL 32-23-1); SDCL 42-8-45 (prohibiting the operation of a boat while under the influence of alcohol); SDCL 50-13-17 (prohibiting persons under the influence of alcohol from operating aircraft); SDCL 32-23-21 (prohibiting minors from operating vehicles if their blood alcohol content is above 0.02); SDCL 35-9-2 (prohibiting minors from consuming alcoholic beverages); SDCL 35-1-5.6 (prohibiting the consumption of alcohol on "the premises of a licensed on-sale dealer if the alcoholic beverage was not purchased from the on-sale dealer"); SDCL 35-1-9.1 (prohibiting the consumption of alcoholic beverages in vehicles on highways or streets); SDCL 35-9-10 (prohibiting social hosts from knowingly permitting eighteen-, nineteen-, or twenty-year-old persons from consuming alcohol); SDCL 32-12A-44 (prohibiting commercial drivers from having a blood alcohol content of 0.04 to 0.08 while being in actual physical control of a commercial vehicle). But without an express repealer, it is unreasonable and absurd to believe that the 2012 Legislature intended such a wholesale repeal of these important public safety statutes. See Myrl & Roy's, 2004 S.D. 98, ¶ 6, 686 N.W.2d at 654 ("[I]n construing statutes together[,] it is presumed that the Legislature did not intend ... absurd or unreasonable result[s].") (quoting Martinmaas v. Engelmann, 2000 S.D. 85, ¶ 49, 612 N.W.2d 600, 611).
[¶ 12.] We hold that the 1974 enactment of SDCL 34-20A-93 and the 2012 repeal of SDCL 34-20A-95 did not prohibit the enforcement of SDCL 32-23-1. Because the State had authority to prosecute Mundy-Geidd for DUI under SDCL 32-23-1, we affirm.
[¶ 13.] GILBERTSON, Chief Justice, and KONENKAMP, SEVERSON, and WILBUR, Justices, concur.
State v. Masteller, 86 S.D. 514, 517, 198 N.W.2d 503, 504-05 (1972). And the element involving blood-alcohol levels does not purport to require any alcohol-related condition. Thus, there are competing plausible interpretations of how SDCL 34-20A-93 applies to SDCL 32-23-1.
