OPINION
LILLEHAUG, Justice.Appellant Michael William Kirby was sentenced to 161 months in prison for first-degree possession of methamphetamine, Minn. Stat. § 152.021, subd. 2(a)(1) (2014). While his case was on appeal, the Drug Sentencing Reform Act (DSRA) took effect. See Act of May 22, 2016, ch. 160, 2016 Minn. Laws 576, The DSRA reduced the presumptive sentencing range under the Minnesota Sentencing Guidelines drug offender sentencing grid for Kirby’s crime. Kirby asks that he be resentenced under the sentencing grid as amended by the DSRA. Because we conclude that such re-sentencing is required, we vacate Kirby’s sentence and remand to the district court.
FACTS
On November 22, 2013, a Steele County Deputy arrested Kirby for possession of 70.525 grams of methamphetamine and 217.55 grams of marijuana. He was charged with first-degree possession of methamphetamine and fifth-degree possession of marijuana, A jury found him guilty of both counts.
The case proceeded to sentencing. Kirby had a criminal history score of seven. Under the sentencing grid in effect at the time of Kirby’s offense,, the presumptive sentencing range was 138 to 192 months. See Minn. Sent. Guidelines 4.A (2013).1 On October 22, 2014, the district court sentenced Kirby to 161 months in prison for first-degree possession of methamphet.amine.
Kirby appealed his case. 'While his appeal was pending, the Legislature passed, and the Governor signed, the DSRA, which reduced the presumptive sentencing range for Kirby’s' offense from 138 to 192 months to 110 to Í53 months. See Act of May 22, 2016, ch. 160, § 18, 2016 Minn. Laws 576, 590-91; Minn. Sent. Guidelines 4.C (2016). The DSRA was the product of input by diverse constituent groups within the criminal justicé system, including county attorneys and criminal defense attorneys. The DSRA distinguishes between low-level, non-violent drug offenders and high-level, dangerous drug dealers by reducing sen-ténces for the former class of offenders. See generally Act of May 22, 2016, ch. 160, 2016 Minn. Laws at 576-92. In'tum, these reduced sentences are expected to reduce prison populations and prison costs, the savings from which will be used to fund a “Community Justice Reinvestment Account.” Id. § 14, 2016 Minn. Laws at 588. Those funds are available to:
[ljocal units of government and nonprofit organizations ... for grants to establish or operate chemical dependency and mental health treatment programs, programs that improve supervision, including pretrial and precharge supervision, and programs to reduce recidivism of controlled substances offenders on probation or supervised release or participating in drug courts or to fund local participation in drug -court initiatives.
Id., subd. 2.
As relevant here, the DSRA changed the controlled-substance laws in several *488ways. First, the DSRA reduced the presumptive sentencing ranges for first-degree controlled-substance crimes. Id. § 18, 2016 Minn. Laws at 590-91. That section became “effective the day following final enactment,” which occurred when the governor signed the act on May 22, 2016. Id. Second, the DSRA increased the weight thresholds necessary for first-, second-, and third-degree possession of methamphetamine. Id. §§ 3-5, 2016 Minn. Laws at 577-82. Those sections became “effective August 1, 2016, and appl[y] to crimes committed on or after that date.” Id. Third, the DSRA added aggravating factors that could be used to increase the degree of an offense for selling or possessing methamphetamine. Id. §§ 2-5, 2016 Minn. Laws at 576-83. Those sections became “effective August 1, 2016, and appl[y] to crimes committed on or after that date.” Id. Finally, the DSRA created a new category of aggravated first-degree controlled-substance crimes. Id. § 3, subd. 2b, 2016 Minn. Laws at 577-79. That change became “effective August 1, 2016, and applies to crimes committed on or after that date.” Id.
Kirby appealed, challenging evidentiary rulings and the sufficiency of the evidence. On July 18, 2016, the court of appeals affirmed Kirby’s convictions. State v. Kirby, No. A15-0117, 2016 WL 3884245 (Minn. App. filed July 18, 2016). Due to the timing of the appeal and the effective date of the DSRA, the court of appeals was not able to consider the issue before us. We granted Kirby’s petition for review on the issue we now decide: whether he is entitled to be resentenced under the sentencing grid as amended by the DSRA.
ANALYSIS
I.
A.
At the outset, it is important to understand what this case is not about: retroactivity. A change in law is considered to be retroactive when it applies to cases in which final judgment has already been entered. See Welch v. United States, — U.S. —, —, 136 S.Ct. 1257, 1264, 194 L.Ed.2d 387 (2016) (discussing the applicability of retroactivity to “ ‘cases which have become final’” (quoting Teague v. Lane, 489 U.S. 288, 310, 109 S.Ct. 1060, 103 L.Ed.2d 334 (1989))).
Instead,.this case is about amelioration. The amelioration doctrine applies to cases that are not yet final when the change in law takes effect. See State v. Coolidge, 282 N.W.2d 511, 514-15 (Minn. 1979) (discussing the applicability of an amended statute “as long as no final judgment has been reached”). A creature of common law, the doctrine is of long standing. See, e.g., Commonwealth v. Wyman, 66 Mass. 237, 239 Mass. 1853 (citing Calder v. Bull, 3 U.S. (3 Dall.) 386, 1 L.Ed. 648 (1798)) (holding that “an act plainly mitigating the punishment of an offence” applied to cases that were not yet final); People v. Hayes, 140 N.Y. 484, 35 N.E. 951, 952-53 (1894) (holding that the mitigating law applied “to offenses committed before its passage” where “a criminal case ... is not yet final”).2
*489The question is whether the amelioration doctrine applies to Kirby, whose conviction was not yet final when the DSRA took effect. Although we have not used the phrase “amelioration doctrine” previously, four of our prior cases have followed and analyzed the doctrine. See Edstrom v. State, 326 N.W.2d 10 (Minn. 1982); Ani v. State, 288 N.W.2d 719 (Minn. 1980); State v. Hamilton, 289 N.W.2d 470 (Minn. 1979); Coolidge, 282 N.W.2d 511. Coolidge and Edstrom are particularly relevant to the question before us.
In Coolidge, the defendant was convicted of criminal sexual conduct and sentenced to 10 years in prison. Coolidge, 282 N.W.2d at 512. Before final judgment was entered, the Legislature repealed and replaced the statute under which Coolidge was convicted, reducing the maximum sentence for his conduct from 10 years to 1 year. Id. at 512-14; see also Act of May 19, 1977, ch. 130, §§ 4, 10, 1977 Minn. Laws 220, 221-23. The act stated that the changes became effective “the day after final enactment,” but it did not say whether the changes applied to offenses committed before the effective date. Act of May 19,1977, ch. 130, § 11,1977 Minn. Laws at 223. We stated:
Under common law, the well-settled principle is that where criminal law in effect is repealed, absent a savings clause, all prosecutions are barred where not reduced to a final judgment. It is also true that a statute mitigating punishment is applied to acts committed before its effective date, as long as no final judgment has been reached. The rationale for such a rule is that the legislature has manifested its belief that the prior punishment is too severe and a lighter sentence is sufficient. Nothing would be accomplished by imposing a harsher punishment, in light of the legislative pronouncement, other than vengeance.
Coolidge, 282 N.W.2d at 514-15 (footnote and citations omitted).
Applying these principles, we noted that “the law under which defendant was convicted was amended in part and repealed after the defendant’s illicit acts were committed but before a final judgment had been reached.” Id. at 515. We then concluded, “in light of the common law and the weight of greater logic, defendant should have been sentenced under the present law, which provides a maximum prison term of 1 year.” Id. We ordered that the sentence be reduced accordingly. Id.
In Coolidge, the Legislature was silent on whether the statutory change should be given ameliorative effect. Edstrom, by contrast, demonstrates the Legislature’s ability to state its intent to abrogate the amelioration doctrine. In Edstrom, the defendant was convicted of aggravated rape and sentenced to 30 years in prison. 326 N.W.2d at 10. Before final judgment was *490entered, the Legislature enacted a new criminal sexual conduct statute that covered Edstrom’s conduct but carried only a 20-year prison sentence. See id.; see also Act of June 5, 1975, ch. 374, § 3, 1975 Minn. Laws 1243, 1245-46. The new statute, however, included a clause captioned, “Applicability to Past and Present Prosecutions,” which stated, in relevant part, that “crimes committed prior to the effective date of this act are not affected by its provisions.” Act of June 5, 1975, ch. 374, § 12, 1975 Minn. Laws at 1251. Edstrom’s conduct occurred in March 1975, while the statute did not take effect until August of that year. See Edstrom, 326 N.W.2d at 10.
In considering the effect of the statutory clause, we stated, “In Coolidge, we ruled that a statute mitigating punishment is to be applied to acts committed before its effective date, as long as no final judgment has been reached, at least absent a contrary statement of intent by the legislature.” Id, We then determined that, in the act at issue in Edstrom,' the Legislature had “clearly indicated its intent” that the amendments not apply to crimes committed prior to the effective date of the,.act, Id. Thus, we concluded that Edstrom was not entitled to the benefit of the new statute, which set a lower sentence for -the crime that Edstrom had committed. Id.
Reading Coolidge and Edstrom together, our rule of law is clear. An amended statute applies to crimes committed before its effective date if: (1) there is no statement by the Legislature that clearly establishes the Legislature’s intent to abrogate the amelioration doctrine; (2) the amendment mitigates punishment; and (3) final judgment has not been entered as of the date the amendment takes effect..
B.
We now consider Kirby’s case. Our precedent requires that he be resentenced under the DSRA-amended sentencing grid only if: (1). the Legislature made no statement that clearly establishes the Legislature’s intent to abrogate the amelioration doctrine; (2) the amendment mitigated punishment; and (3) final»judgment had not been entered as of the date the amendment took effect. The parties agree that the third requirement is satisfied, but dispute the first two requirements. We consider each in turn.
1.
The State acknowledges that the amelioration doctrine establishes a presumption ⅛ Minnesota that an. amendment mitigating punishment applies to non-final cases. But the State argues , that the presumption is “overcome by contrary legislative intent” in this case. Kirby argues that there is no such clear indication of the Legislature’s intent to abrogate the amelioration doctrine.
The effective-date provision for DSRA § 18 states, “This section is effective the day following final enactment.” Act of May 22, 2016, ch. 160, § 18, 2016 Minn. Laws at 591. This effective-date provision is almost identical to the language in the act that we interpreted in Coolidge. Compare Act of May 19, 1977, ch. 130, § 11, 1977 Minn. Laws at 223 (stating that the act is “effective the day after final enactment”), with Act of May 22, 2016, ch, 160, § 18, 2016 Minn. Laws at 591 (stating that DSRA § 18 is “effective the day following final enactment”). We determined that the act containing this language did not abrogate the common-law amelioration doctrine, Coolidge, 282 N.W.2d at 514-15.
The Legislature has instructed us that, “when a court- of last» resort has construed the language of a law, the legislature in subsequent laws on the same subject matter intends the same construction to be placed upon such language.” Minn. Stat. *491§ 645.17(4) (2016). Thus, when the Legislature enacted language in DSRA § 18 mirroring the language of the act that we interpreted in Coolidge, we may assume that the Legislature intended the DSRA to carry the same meaning as the act at issue in Coolidge.
Moreover, the Legislature knows how to expressly abrogate the amelioration doctrine, as it did in the act at issue in Edstrom, 326 N.W.2d at 10. There is no language in DSRA § 18 that resembles the language at issue in Edstrom. See Act of June 5, 1975, ch. 374, § 12, 1975 Minn. Laws at 1251 (titled “Applicability to Past and Present Prosecutions,” and stating, “Except for section 8 of this act, crimes committed prior to the effective date of this act are not affected by its provisions”). Here, the Legislature has not “clearly indicated its intent,” like it did in the act before us in Edstrom, to abrogate the amelioration doctrine. Edstrom, 326 N.W.2d at 10.
To the contrary (and perhaps most importantly), the Legislature expressly stated in other sections of the DSRA that those sections only “appl[y] to crimes committed on or after” the effective date. See Act of May 22, 2016, ch. 160, §§ 1-10, 15-17, 2016 Minn. Laws at 576-85, 588-90. The absence of such language from DSRA § 18 is telling; it signals that the Legislature did not intend to abrogate the amelioration doctrine. See Rohmiller v. Hart, 811 N.W.2d 585, 590-91 (Minn. 2012) (stating that the court cannot add to a statute words that were intentionally or inadvertently left out by the Legislature); Van Asperen v. Darling Olds, Inc., 254 Minn. 62, 93 N.W.2d 690, 698 (1958) (stating that the court construes a law as a whole and interprets each section in light of the surrounding sections).
The State nevertheless argues that the Legislature did, indeed, abrogate the amelioration doctrine in DSRA § 18. It lists five reasons in support of its view.3 First, the State argues that Coolidge-Edstrom is limited to legislation that reduces the statutory maximum sentence that may be imposed, and does not, therefore, apply to the presumptive sentences in the Guidelines. It is true that all four of our amelioration doctrine cases involved sentences that predated the Guidelines. But analysis of how the sentencing grids in the Guidelines are amended by the Legislature and applied by sentencing .judges shows that the same reasoning that controlled in Coolidge and Edstrom applies to the sentencing grids as well. . ...
The operative language from Edst-rom is that the amelioration doctrine applies to “a statute mitigating punishment.” Edstrom, 326 N.W.2d at 10. The DSRA amended criminal drug-possession statutes and specific corresponding portions of the drug-offender sentencing grid. See generally Act of May 22, 2016, ch. 160, 2016 Minn. Laws at 576-92. And changes to sentencing grids must be approved (by vote or by failure to vote) by the Legislature. See Minn. Stat. § 244.09, subd. 11 (2016) ‘(“Any modification which amends the Sentencing Guidelines grid .., shall be submitted to the legislature....”). The sentencing grid constitutes the “statutory maximum” sentence a court can impose absent additional facts found by a jury. State v. Shattuck, 704 N.W.2d 131, 137, 141-42 (Minn. 2005). Accordingly, the amelioration doctrine applies to legislation amending the sentencing grids with the *492same force as to laws amending criminal statutes.
Second, the State argues that the effective date of DSRA § 18 is different from the other sections of the DSRA because the Legislature was merely instructing the Minnesota Sentencing Guidelines Commission, rather than itself amending a statute. We do not consider this a meaningful distinction. After the DSRA was passed by the Legislature and signed by the Governor, all that was left for the Commission to do was the ministerial task of revising the Guidelines as instructed.4
Third, the State argues that the DSRA’s legislative history includes a statement of intent to abrogate the amelioration doctrine. But legislative history is relevant only if the statute is ambiguous. State v. McKown, 475 N.W.2d 68, 66 (Minn. 1991). Here, the plain language of DSRA § 18 is unambiguous in light of Coolidge. Moreover, other provisions of the DSRA provide a stark contrast to DSRA § 18 in the way they deal with the amelioration doctrine. And in all four of our cases applying the amelioration doctrine, we have looked solely at the text of the law—not legislative history—to determine whether there was a contrary statement of intent by the Legislature. See Edstrom, 326 N.W.2d at 10; Ani, 288 N.W.2d at 720; Hamilton, 289 N.W.2d at 474-75; Coolidge, 282 N.W.2d at 514-15.
But even if we were to consider the legislative history cited by the State, we cannot locate any statement showing a clear intent to abrogate the amelioration doctrine. Specifically, the State points to the Judiciary Committee’s closing comments on the DSRA, during which the bill’s author, Senator Ron Latz, stated: “There’s stuff I wanted that’s not in here. I wanted retroactivity—the opportunity for current incarcerated persons to be able to petition, to bring a motion to the district court to get resentenced under any new guidelines that take effect.... I didn’t get [that].” Hearing on S.F. 3481, Sen. Judiciary Comm., 89th Minn. Leg., Apr. 8, 2016 (video) (statement of Sen. Latz), at 4:33:00-4:33:30.5
We read this statement to refer to retro-activity, not amelioration. The comment about “current incarcerated persons” seems to refer to offenders finally adjudged and serving their prison sentences. This statement comes nowhere close to showing that the Legislature “clearly indicated its intent” to abrogate the amelioration doctrine. See Edstrom, 326 N.W.2d at 10.
Fourth, the' State and the dissent argue that the Guidelines themselves—specifically Guidelines 3.G and the introduction to Guidelines 2—constitute a statement of intent by the Legislature to abrogate the doctrine. But these portions of the Guidelines—unlike the DSRA amendments to the drug offender sentencing grid—were adopted by the Sentencing Commission, not by the Legislature. Compare Minn. Stat. § 244.09, subd. 5 (2016) (“The Commission shall promulgate Sentencing Guidelines for the district court.”), with id., subd. 11 (stating that the Commission is required to obtain the Legislature’s approval only for modifications which amend the “Sentencing Guidelines grid”). In contrast, the Commission is required to obtain the Legislature’s approval to modify the “Sentencing Guidelines grid, including severity levels and criminal history scores, or *493which would result in the reduction of any sentence or in the early release of any inmate.” Id., subd. 11. We have never ruled—and decline to rule today—that the amelioration doctrine may be abrogated by Commission statements not ratified by the Legislature.
In any evept, neither portion of the Guidelines abrogates the amelioration doctrine. The rules of statutory interpretation and construction apply to the Guidelines. State v. Campbell, 814 N.W.2d 1, 4 (Minn. 2012). Thus, we read them as a whole and interpret each section in light of the surrounding sections. Van Asperen, 93 N.W.2d at 698.
Guidelines 3.G discusses how to apply “Policy Modifications” to the Guidelines:
1. Policy Modifications. Modifications to the Minnesota Sentencing Guidelines and associated commentary apply to offenders whose date of offense is on or after the specified modification effective date.
2. Clarifications of Existing Policy. Modifications to Commentary relating to existing Guidelines policy apply to offenders sentenced on or after the specified effective date.
Minn. Sent. Guidelines 3.G.
Reading the Guidelines as a whole, the phrase “Policy Modifications” plainly refers to modifications to Guidelines 1 through 3, not to Guidelines 4, the sentencing grids. Sentencing “policy” is covered in Guidelines 1 through 3. For example, Comment 2.B.115 to Guidelines 2.B.1 discusses “[a]ll of the policies under section 2.B.1, and corresponding commentary.” Minn. Sent. Guidelines 2.B.1 cmt. 2.B.115. Those policies explain, among other things, how to account for extended-jurisdiction juvenile convictions, multiple sentences based on a single course of conduct, prior felony convictions that resulted in misdemeanor sentences, and stays of imposition. See generally Minn. Sent. Guidelines 2.B.I. Similarly, Guidelines 2.C.3.e mentions the “presumptive sentencing consecutive policy (see section 2.F.1, Presumptive Consecutive Sentences).” Minn. Sent. Guidelines 2.C.3.e. In turn, Guidelines 2.F provides the policy for an offender who is convicted of “multiple current offenses” or has a “prior felony sentence that has not yet expired or been discharged” at the time of sentencing. Minn. Sent. Guidelines 2.F. Further, Guidelines 3, aptly titled “Related Policies,” addresses stayed sentences, calculation of jail credit, certified juveniles, presentence examinations for sex offenders, military veterans, and modifications. See generally Minn. Sent. Guidelines 3. Finally, even when a sentencing grid mentions “policy,” it plainly refers to Guidelines 1 through 3, not the sentencing grid itself. Minn. Sent. Guidelines 4.A n.1 (“See section 2.E, for policies regarding those sentences controlled by law.”).
Throughout the Guidelines, the term “policy” is never used in reference to the sentencing grids. The most reasonable interpretation of Guidelines 3.G, then, is that it applies to Guidelines 1 through 3, not the sentencing grids in Guidelines 4. Thus, Guidelines 3.G does not abrogate the amelioration doctrine as to the presumptive sentences in the grid.
The State and dissent also point to the introduction to Guidelines 2 as a statement of intent to abrogate the amelioration doctrine. This introduction states: “The presumptive sentence ... is determined by the Sentencing Guidelines in effect on the date of the conviction offense.... ” Minn. Sent. Guidelines 2. We do not read this language to abrogate the amelioration doctrine; we read it to ensure that the Guidelines abide by the federal and state Ex Post Facto Clauses. See U.S. Const. art. I, § 10; Minn. Const. art. I, § 11. A *494sentencing judge violates the Ex Post Fac-to Clause if the judge sentences a .defendant under a law that “change[d] the punishment, aud inflicts a greater punishment, than the law annexed to the crime, when committed.” Calder, 3 U.S. at 390; see also Peugh v. United States, — U.S. —, —, 133 S.Ct. 2072, 2088, 186 L.Ed.2d 84 (2013) (applying Calder v. Bull to hold that a sentencing judge violates the Ex Post Facto Clause if the judge sentences a defendant under guidelines with a higher sentencing range than the guidelines in effect at the time of the offense).
Moreover, nothing in the history of the introduction to Guidelines 2 shows that the Commission intended to abrogate-the amelioration doctrine. The relevant language was added in 2012 as part of the Commission’s Guidelines Revision Project. See Minnesota Sentencing Guidelines Commission, Guidelines Revision Project: Adopted Modifications 16 (Apr. 2012). The purpose of the Project was to make the Guidelines “easier to read, use, and understand.” Id. at 3. The Commission emphasized that its revision “was primarily stylistic ... rather than substantively rewriting the Guidelines.” Id. Certainly, adding an express, ongoing abrogation of the amelioration doctrine would have been substantive. Making such a substantive change does not seem to have been the Commission’s intent during the Revision Project.
Fifth, the State argues that two statutes other than the DSRA, and the legislative history of a third' statute, contain statements of intent by the Legislature to abrogate' the amelioration doctrine generally. We consider each possibility in turn.
The first statute relied upon by the State is . a general savings clause, Minn. Stat. § 645.21 (2016), which states, “No law shall be construed to be retroactive unless clearly and manifestly so intended by the legislature,” But this statute applies to retroactivity, not the amelioration doctrine. See State v. Morrissey, 271 Minn. 123, 135 N.W.2d 57, 60 (1965).
The second statute, Minn. Stat. § 645.35 (2016), is another general savings clause. That statute states, in relevant part, “The repeal of any law shall not affect any right accrued, any duty imposed, any penalty incurred, or any proceeding commenced, under or by virtue of the law repealed.” Id. In support of its argument that this statute establishes the Legislature’s intent to abrogate the amelioration doctrine, the State cites State v. Smith, 62 Minn. 540, 64 N.W. 1022, 1022 (1895), in which the defendant was convicted under a statute that was later repealed and replaced with a statute that changed the classification of the defendant’s crime from a misdemeanor to a felony. The defendant argued that he could not be prosecuted under the new statute for ex post facto reasons, and that he could not be prosecuted under the old statute because it had been repealed. Id. at 1022. We disagreed with the defendant’s second contention, concluding that the State was not required to abate its prosecution under the repealed statute. Id. at 1023.
In other words, as we recognized in Smith, section , 645.35 abrogates the “abatement doctrine,” not the amelioration doctrine. The abatement doctrine is a common law presumption that the Legislature’s repeal of a criminal statute requires the State to halt its prosecutions under the repealed statute.6 See, e.g., Commonwealth v. Kimball, 38 Mass. 373, 374 (1838) (de-*495termining that the statute under which the defendant was-, convicted “has been repealed without any saving provision ... so that no judgment can now be rendered”). Savings clauses like section 645.35 close a loophole that would otherwise exist due to the interplay between the abatement doctrine and the Ex Post Facto Clause. See La Porte v. State, 14 Ariz. 530, 132 P. 563, 564-65 (1913) (explaining that, in the absence of Arizona’s savings clause, which mirrors Minn. Stat. § 645.35, repealing a criminal statute would “effect many legislative pardons”).7
Finally, the State .argues that the Legislature’s enactment and repeal of retroac-tivity provisions in Minn. Stat. § 244.09, subd. 11, reveals a- legislative intent to abrogate the amelioration doctrine. In 1983, the Legislature amended section 244.09, subdivision IT, to state, “Any modification of the guidelines- that- causes a duration change shall be retroactive for all 'inmates serving sentences imposed pursuant to the Minnesota sentencing guidelines if the durational-change reduces the appropriate term of imprisonmént.” Act of June 6, 1983, ch. 274, § 10, 1983 Minn. Laws 1171, 1177. The next year, the Legislature repealed this clause and enacted a new subdivision, 11a, providing a process by which a prisoner could petition for retroactive application of lesser sentencing guidelines. Act of April 26, 1984, ch. 589, §§ 4-5, 1984 Minn. Laws 1235, 1236-37. The Legislature then repealed subdivision 11a in 1997. Act of May 30, 1997, ch. 239, art. 3, § 25,1997 Minn. Laws 2742, 2786.
The State argues that the Legislature’s decision to repeal the retroactivity provision demonstrates the Legislature’s intent to abrogate the amelioration doctrine. This argument fails. The plain language of both the 1983 clause and subdivision 11a applied to retroactivity, not the amelioration doctrine. Moreover, at best, the repeal of the retroactivity provision leaves the.statute neutral as to the amelioration doctrine, meaning that the presumption that the amelioration doctrine applies remains intact.
In sum, the Legislature made no statement that clearly establishes its intent to abrogate the amelioration doctrine with respect to DSRA § 18.
'2.
Finally, we consider whether either DSRA § 18, or the DSRA as a whole, mitigate punishment. This is the other disputed element of the amelioration doctrine.
The State and the dissent argue that DSRA § 18, and the DSRA as a whole, do not mitigate punishment. The dissent points out that DSRA § 18(b) increased the presumptive sentences from those proposed by the Commission, which the Legislature rejected in DSRA § 18(a). See Act of May 22, 2016, ch. 160, § 18, 2016 Minn. Laws at 590-91. The dissent’s theory is that DSRA §§ 18(a)-(b) actually increased the presumptive sentences from those decreased by the Commission’s proposals. But this is a false dichotomy. The correct comparison is whether the Legislature reduced the presumptive sentences from those in the sentencing grid under which Kirby was sentenced. This comparison fits each of our four prior amelioration doctrine cases, which looked at the specific provision affecting the criminal defendant. Edstrom, 326 N.W.2d at 10; Ani, 288 N.W.2d at 720; Hamilton, 289 N.W.2d at 474-75; Coolidge, 282 N.W.2d at 514-15. Here, DSRA § 18(b) reduced Kirby’s pre*496sumptive sentencing range from 138 to 192 months to 110 to 153 months. The amendment plainly mitigates punishment.
Moreover, the DSRA as a whole generally mitigates punishment. To be sure, the DSRA created a new crime, “aggravated controlled substance crime in the first degree,” and it added new aggravating factors that could be used by prosecutors to argue for increased sentences for some controlled substance offenses. Act of May 22, 2016, ch. 160, §§ 2-3, 2016 Minn. Laws at 576-79. But the thrust of the DSRA is mitigation. The Legislature contemplated that reduced sentences for the majority of drug offenders would reduce prison populations and costs, producing savings for programs that help drug addicts and low-level offenders. Id. § 14, 2016 Minn. Laws at 588. Overall, the DSRA mitigates punishment, and it especially does so for offenders such as Kirby.
In conclusion, Kirby meets the three requirements of the amelioration doctrine. First, no statement by the Legislature clearly demonstrates an intent to abrogate the doctrine. Second, the DSRA mitigates punishment. Third, Kirby has not had final judgment entered in his ease. Accordingly, Kirby must be resentenced under the DSRA-amended sentencing grid.
The conclusion that we reach today is required by a common-law rule more than 160 years old, as adopted by our own precedent that is almost 40 years old. Sentencing policy is for the Legislature and the Commission to make. See Minn. Stat. § 609.095(a) (2016); Reynolds v. State, 888 N.W.2d 125, 132 (Minn. 2016); State v. Meyers, 869 N.W.2d 893, 896 (Minn. 2015). Our judicial role is to interpret and apply the sentencing law, including the sentencing grids established and amended by the Legislature. Had the Legislature given us a clear signal that DSRA § 18(b) did not apply to defendants with non-final convictions, we would have followed that signal. Because it did not, we apply our long-established rule of law.
CONCLUSION
For the foregoing reasons, we vacate Kirby’s sentence and remand to the district court for resentencing consistent with this opinion.
Sentence vacated; remanded.
. Included in the presumptive sentencing range was a 3-month increase for a custody enhancement. See Minn. Sent. Guidelines 2.B.2 (2013).
. The common-law amelioration doctrine is widely recognized. See, e.g., In re Estrada, 63 Cal.2d 740, 48 Cal.Rptr. 172, 408 P.2d 948, 951 (1965) (holding that a defendant “is entitled to the ameliorating benefits of the statutes as amended” if “the amendatory statute lessening punishment becomes effective prior to the date the judgment of conviction becomes final"); People v. Schultz, 435 Mich. 517, 460 N.W.2d 505, 511 (1990) (“[I]n the absence of a contrary statement of legislative intent, criminal defendants are to be sentenced under an ameliorative amendatory act that is enacted subsequent to the date of offense and becomes effective during the pen-dency of the prosecution.”); State v. Cummings, 386 N.W.2d 468, 472 (N.D. 1986) *489("We conclude that, unless otherwise indicated by the Legislature, an ameliorating amendment to a criminal statute ... should be applied to offenses committed prior to its effective date, provided that the defendant has not yet been finally convicted of the offense.”); People v. Oliver, 1 N.Y.2d 152, 151 N.Y.S.2d 367, 134 N.E.2d 197, 201 (1956) ("And, indeed, where an ameliorative statute takes the form of a reduction of punishment for a particular crime, the law is settled that the lesser penalty may be meted out in all cases decided after the effective date of the enactment, even though the underlying act may have been committed before that date.”); see also Amelioration Doctrine, Black's Law Dictionary (10th ed. 2014) ("The rule that if a new statute reduces the penalty for a certain crime while a prosecution for that crime is pending, the defendant should gain the benefit of the reduction even though the crime was committed before the statute passed.”).
. The State raised several of these arguments in a companion case, State v. Otto, No. A15-1454, slip op., 899 N.W.2d 501, 2017 WL 3161109 (Minn. July 26, 2017), also released today. We consider all of the State’s arguments here.
. Although not precisely analogous, this process mirrors how the Revisor of Statutes incorporates statutory amendments passed by the Legislature. See Minn. Stat. § 3C.08, subd. 4 (2016).

. This is distinct from the "doctrine of abatement ab initio,” which directs that the "death [of a defendant] pending direct review of a criminal conviction discontinues not only the appeal but also all proceedings in the prosecution from the beginning.” State v. Burrell, 837 N.W.2d 459, 463 (Minn. 2013).
, Neither general savings clause (Minn. Stat. §§ 645.21, 645.35) was mentioned in our line of cases on the amelioration doctrine. Both general savings clauses were enacted in 1941. Our four amelioration cases were decided from 1979 to 1982.
