OPINION
WILLIS, Judge.*In this pretrial appeal, the state argues that the district court erred by finding respondent’s right to substantive due process requires that an intent requirement be read into Minn.Stat. § 340A.503, subd. 2(1). Because section 340A.503, subdivision 2(1), creates a strict-liability offense and does not violate due-process rights, we reverse and remand.
FACTS
On November 14, 2011, respondent Stacy Marie Rohan was working at a restaurant in Burnsville, Minnesota. Two undercover police officers accompanied by a woman under the age of 21 sat in the bar area of the restaurant and ordered beer. Respondent checked each person’s identification and then served beer to the underage woman. The underage woman’s identification showed her correct age. Respondent was charged with serving alcohol to an underage person, in violation of MinmStat. § 340A.503, subd. 2(1).
Respondent moved the district court for an order either invalidating the statute under the due-process clauses of the United States and Minnesota constitutions or directing that, to obtain a conviction, the state must prove that respondent intentionally violated the law. The district court held that respondent could not be held strictly liable under the statute without violating her due-process rights. It issued an order requiring the state to prove that respondent intentionally violated the statute.
The state then brought the present appeal, under Minn.R.Crim. P. 28.04, subd. 1(1).
ISSUES
I. Did the district court err in construing MinmStat. § 340A.503, subd. 2(1) (2010), to include an intent element?
II. Did the district court err in holding that prosecuting the respondent under Minn.Stat. § 340A.503, subd. 2(1), would violate her right to due process unless the statute is read to include an intent element?
ANALYSIS
As a threshold matter, we consider whether the district court’s order is immediately appealable. Under the Minnesota Rules of Criminal Procedure, the state *226may appeal an adverse pretrial ruling. Minn.R.Crim. P. 28.04, subd. 1(1). But to obtain review, the state must “clearly and unequivocally” show that the order will have a “critical impact” on the state’s case. State v. Scott, 584 N.W.2d 412, 416 (Minn.1998) (quotation omitted). Upon such a showing, this court may proceed to determine whether the pretrial ruling was erroneous. Id.
Requiring the state to prove intent to violate the statute at issue here clearly and unequivocally has a critical impact on the state’s case. The district court’s ruling would require the state to prove an element of the offense that does not appear on the face of the statute. The state has satisfied the critical-impact requirement, and we may consider the present appeal. See State v. Zais, 805 N.W.2d 32, 36 (Minn.2011) (instructing that critical impact exists when district court’s order “significantly reduces the likelihood of a successful prosecution”) (quotations omitted).
Having concluded that this pretrial appeal is proper, we turn to the substantive issues raised by the state. Because respondent’s constitutional argument is contingent on our determination of whether Minn.Stat. § 340A.503, subd. 2(1), includes an intent requirement, we first address the statutory-interpretation issue. See Rickert v. State, 795 N.W.2d 236, 240 (Minn.2011) (“Generally, we will not address a constitutional issue if there is another basis upon which the case can be decided.”).
I. Serving alcohol to underage persons is a strict-liability crime in Minnesota.
The district court concluded that the legislature did not intend for Minn. Stat. § 340A.503, subd. 2(1), to impose strict criminal liability. Determining the presence or absence of an intent, or mens rea, element in a criminal statute calls for statutory interpretation. United States v. Balint, 258 U.S. 250, 251-52, 42 S.Ct. 301, 302, 66 L.Ed. 604 (1922). Statutory interpretation is a question of law and is reviewed de novo. State v. Ndikum, 815 N.W.2d 816, 818 (Minn.2012).
“Mens rea is the element of a crime that requires ‘the defendant know the facts that make his conduct illegal.’ ” Id. at 818 (quoting Staples v. United States, 511 U.S. 600, 605, 114 S.Ct. 1793, 1796-97, 128 L.Ed.2d 608 (1994)). “Statutes that dispense with mens rea and ‘do not require the defendant to know the facts that make his conduct illegal’ impose strict criminal liability.” Id. (quoting Staples, 511 U.S. at 606, 114 S.Ct. at 1793).
Relying on United States Supreme Court precedent disfavoring offenses that do not require mens rea, the Minnesota Supreme Court has stated that it is “guided by the public policy that if criminal liability, particularly gross misdemeanor or felony liability, is to be imposed for conduct unaccompanied by fault, the legislative intent to do so should be clear.” State v. Neisen, 415 N.W.2d 326, 329 (Minn.1987). The court has thus instructed that, except with respect to statutes creating public-welfare offenses, “some positive indication of legislative intent is required to dispense with mens rea.” Ndikum, 815 N.W.2d at 818-19 (citing Staples, 511 U.S. at 620, 114 S.Ct. at 1793). Applying this principle, the Minnesota Supreme Court has read intent elements into statutes imposing gross-misdemeanor or felony liability for possessing firearms or other weapons in certain locations. Ndikum, 815 N.W.2d at 822 (possession of a pistol in public); In re Welfare of C.R.M., 611 N.W.2d 802, 810 (Minn.2000) (possession of a knife at school).
Were we addressing the issue raised in this case as a matter of first *227impression, our analysis would properly begin with an application of the principles enunciated in the supreme court’s recent decision in Ndikum to determine whether intent is a required element of a violation of Minn.Stat. § 340A.503, subd. 2(f).1 But when the supreme court has already construed a statute, this court is bound by that interpretation. Jendro v. Honeywell, Inc., 392 N.W.2d 688, 691 n. 1 (Minn.App.1986), review denied (Minn. Nov. 19, 1989). Moreover, we must presume 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. § 645.17 (2012); see also Minn.Stat. § 645.16 (2012) (when interpreting legislative intent, this court may look to “the former law, if any, including other laws upon the same or similar subjects”). Similarly, when the legislature fails to amend a statute that has been interpreted by the supreme court, the legislature is deemed to have acquiesced to that interpretation. See Engquist v. Loyas, 803 N.W.2d 400, 406 (Minn.2011) (stating that, because legislature did not amend statute in response to supreme court’s interpretation, “we assume that the Legislature has acquiesced in our interpretation”); State, Dep’t of Pub. Safety v. Ogg, 310 Minn. 433, 436, 246 N.W.2d 560, 562 (1976) (stating that legislature’s failure to amend statute following interpretation despite “several” intervening legislative sessions suggests acquies-eence). Here, the interpretation to be given to Minn.Stat. § 340A.503, subd. 2(1), is supplied by the history of the statute and the caselaw construing it.
The sale of liquor to underage persons has been illegal in Minnesota for 141 years.2 On March 4, 1872, the state legislature enacted a statute providing that “[i]t shall be unlawful for any person to sell, give, barter, furnish, or dispose of ... fermented or malt liquors ... to any minor person, pupil or student ..., or habitual drunkard.” 1872 Minn. Laws ch. 41, § 11, at 127-28 (codified as amended at Minn.Gen.Stat. ch. 16, § 10 (1878)). Several years later, in a case involving the sale of liquor to a “habitual drunkard,” the supreme court was called on to determine whether intent was an element of the statute. See State v. Heck, 23 Minn. 549, 550 (1877). The supreme court held that it was not. Id. The court stated that “when, without reference to intent, the statute forbids the doing of an act in certain circumstances, and a party is under no obligation to do it, ... if he does the forbidden act he violates the law, irrespective of his knowledge or ignorance of the circumstances mentioned.” Id.
After Heck, the statute governing alcohol sales to underage persons was understood to impose strict liability. In 1936, the Minnesota Attorney General was asked what precautions a business could take to avoid liability under the law. Minn. Op. Att’y Gen.No. 302 (1936), cited in Neisen, *228415 N.W.2d at 328. The attorney general responded that, “[r]egardless of the precaution taken, if a sale was made to a customer under the age of 21 years the seller would be guilty of violation of this statutory provision.” Id.
During the century following the Heck decision, the legislature amended the statute governing underage alcohol sales multiple times. See, e.g., 1947 Minn. Laws ch. 87, § 1; 1949 Minn. Laws ch. 415, § 1; 1953 Minn. Laws ch. 483, §§ 1, 2. But none of the amendments added an intent requirement. In 1957, the legislature amended the statute to provide an affirmative defense, known as the “carding defense,” which excused from criminal liability sellers who could prove that they made a good-faith attempt to determine that a buyer was of age. See 1957 Minn. Laws ch. 823, § 1, at 1164-65 (codified at Minn. Stat. § 340.942 (1957)). Importantly, this defense would have been unnecessary if the state carried the burden to prove that a defendant knew that the buyer was underage.
In 1985, the legislature cleared the board, repealing the then-existing statute and replacing it with Minn.Stat. § 340A.503. See 1985 Minn. Laws. ch. 305, art. 13, § 1. The newly codified version omitted the affirmative-defense provision, but added a provision governing the methods by which a purchaser’s age could be proved. Neisen, 415 N.W.2d at 328-29 (citing Minn.Stat. § 340A.503 (1986)).
In Neisen, decided 100 years after Heck, the supreme court held that the recodified statute was ambiguous and concluded that, despite the omission of the affirmative-defense language, the legislature intended to preserve the carding defense. 415 N.W.2d at 329. In so holding, the court expressly reinforced its holding in Heck, stating that “the state does not have to prove the defendant knew the purchaser was underage” in order to prove a violation of the statute prohibiting alcohol sales to underage persons. Id. at 328-329.3
The legislature has amended Minn.Stat. § 340A.503 more than once since Neisen. See, e.g., 1989 Minn. Laws ch. 301, § 14; 1990 Minn. Laws ch. 602, art. 5, §§ 2-4; 1991 Minn. Laws ch. 68, § 1. But like other amendments following Heck, none of the legislative amendments since Neisen has introduced an intent element. In fact, in 1989, the legislature amended the statute to once again include an express carding defense, which, as we note above, would not be necessary if the statute included an intent requirement. See 1989 Minn. Laws ch. 301, § 14. Neisen’s statements on the issue of intent remain the law, and we are bound by the supreme court’s interpretation of the statute. Jendro, 392 N.W.2d at 691 n. 1. The district court’s holding that Minn.Stat. § 340A.503, subd. 2(1), is not a strict-liability crime is contrary to long-standing precedent and is erroneous.
II. The due-process requirements of the United States and Minnesota constitutions do not require that criminal statutes include an intent element.
The district court held that respondent’s right to due process would be *229violated if Minn.Stat. § 340A.503, subd. 2(1), is construed to impose strict criminal liability. The constitutionality of a statute is a question of law, subject to de novo review. In re Conservatorship of Foster, 547 N.W.2d 81, 84-85 (Minn.1996).
Both the Minnesota and federal constitutions prohibit the state from depriving a criminal defendant of “life, liberty or property without due process of law.” U.S. Const. amend. XIV, § 1; Minn. Const. art I, § 7. Minnesota is “free to interpret the Minnesota Constitution as affording greater protection ... than the United States Constitution,” but our courts “ ‘will [not] cavalierly construe our constitution more expansively than the United States Supreme Court has construed the federal constitution.’” State v. Askerooth, 681 N.W.2d 353, 361-62 (Minn.2004) (quoting State v. Fuller, 374 N.W.2d 722, 726-27 (Minn.1985)). It is well established that the due-process clause of the Minnesota Constitution does not extend greater protection against governmental interference than the Due Process Clause of the Fourteenth Amendment. Kahn v. Griffin, 701 N.W.2d 815, 826 (Minn.2005) (citing Anderson v. City of St. Paul, 226 Minn. 186, 190, 32 N.W.2d 538, 541 (1948)). But see State v. Guminga, 395 N.W.2d 344, 349 (Minn.1986) (striking down a statute “specifically and exclusively” under Minn. Const. art. I, § 7, while expressing confidence that the United States Supreme Court would take the same action under the Fourteenth Amendment).
The state’s police power encompasses those “powers of government inherent in every sovereignty.” Nebbia v. New York, 291 U.S. 502, 524, 54 S.Ct. 505, 510, 78 L.Ed. 940 (1934) (quotation omitted). An act criminalizing the sale of liquor to minors is an exercise of police power. State v. Shevlin-Caipenter Co., 99 Minn. 158, 166-67, 108 N.W. 935, 938 (1906), aff'd, 218 U.S. 57, 30 S.Ct. 663, 54 L.Ed. 930 (1910); see also Anderson, 226 Minn. at 190-91, 32 N.W.2d at 541 (stating that “[sjelling intoxicating liquor for use as a beverage is a mere privilege subject to the police power of the state” and describing the broad authority of the government to regulate and even prohibit the sale of alcohol).
A state may invoke its police power to enact a criminal statute that does not include an element of intent without violating due process. Balint, 258 U.S. at 252, 42 S.Ct. at 302; see also Pacific Mut. Life Ins. Co. v. Haslip, 499 U.S. 1, 15, 111 S.Ct. 1032, 1041, 113 L.Ed.2d 1 (1991) (“[Ijmpos-ing such liability is not fundamentally unfair and does not in itself violate the Due Process Clause.”).
In Shevlin-Carpenter Co., the Minnesota Supreme Court was asked to declare invalid under state and federal due-process provisions a statute establishing a strict-liability felony and a civil penalty for harvesting lumber from state-owned land without a valid license. 99 Minn. at 160-61, 108 N.W. at 935. The court held that the provision was a constitutional exercise of police power and expressly compared it “to the statutes prohibiting the sale of liquor to minors” and other strict-liability offenses. Id. at 166-67, 108 N.W. at 938. It held that “[i]n so dispensing with the wrongful intent, the Legislature violated no constitutional right of the citizen, and the statute must be enforced.” Id. at 167, 108 N.W. at 938. The United States Supreme Court affirmed and referred to the examples of valid exercises of police power that the Minnesota Supreme Court had enumerated. Shevlin-Carpenter Co. v. Minnesota, 218 U.S. 57, 69-70, 30 S.Ct. 663, 666-67, 54 L.Ed. 930 (1910). The Supreme Court noted that, while “such legislation may, in particular instances, be harsh, ... this court cannot set aside legis*230lation because it is harsh.” Id. at 70, 30 S.Ct. at 667.
Here, the district court cited a number of state and federal decisions for the proposition that due process requires criminal intent to be imputed in a statute that is silent on the issue. Our review of those cases shows that they were not decided on due-process grounds but rather as matters of statutory interpretation. They do not, therefore, support the district court’s ruling that respondent’s due-process rights would be violated if Minn.Stat. § 340A.503, subd. 2(1), imposes strict criminal liability. See, e.g., Staples v. United States, 611 U.S. 600, 605, 114 S.Ct. 1793, 1796-97, 128 L.Ed.2d 608 (1994) (“[W]e have long recognized that determining the mental state required for commission of a federal crime requires ‘construction of the statute and ... inference of the intent of Congress.’ ” (quoting Balint, 258 U.S. at 253, 42 S.Ct. at 302)); Ndikum, 815 N.W.2d at 818; C.R.M., 611 N.W.2d at 805.
Respondent also argues that the statute violates due process under Guminga, 395 N.W.2d at 349. Guminga struck down a statute imposing vicarious strict liability on a business owner when an employee sold alcohol to an underage person. Id. In doing so, the supreme court noted that “it is a deterrent enough that the employee who sells to the minor can be charged under the statute and that the business is subject to fines or the suspension or revocation of license.” Id. (emphasis added). Guminga held that “no one can be convicted of a crime punishable by imprisonment for an act he did not commit, did not have knowledge of, or give express or implied consent to the commission thereof.” Id.
Guminga is not applicable here. This case involves the application of direct, not vicarious, strict liability. Respondent herself allegedly committed the act for which she may be convicted. Furthermore, Gu-minga indicated that “the employee who sells to the minor” could be charged under the statute. Id. The state alleges that respondent is such an employee.
The district court erred in holding that respondent’s right to due process required it to read an element of intent into Minn. Stat. § 340A.503, subd. (2)(1).
DECISION
The state may create strict-liability crimes without violating the due-process clauses of the United States and Minnesota constitutions. The prohibition on the sale of alcohol to underage persons is such a crime. The district court’s holding to the contrary was error.
Reversed and remanded.

. Under that analysis, statutes that are silent on the issue of intent are presumed to require proof of mens rea unless they create public-welfare offenses. Ndikum, 815 N.W.2d at 819-20. We question whether Minn.Stat. § 340A.503 is ''silent'' on the issue of intent, particularly given the legislature's inclusion of the carding defense, which would not be necessary if the state were required to prove intent as an element of the offense. We need not resolve this issue, however, because we conclude that our decision in this appeal is controlled by existing Minnesota Supreme Court precedent.
. Before 1872, the parent of a minor could provide a tavern keeper with written notice that the minor was not to be served alcohol, and the service of alcohol to the minor after such notice was a crime. Minn.Gen.Stat. ch. 16, § 10 (1866).
. At oral argument, respondent argued that this language in Neisen is dictum. But absent strict liability, there would have been no need for the supreme court to find an implied carding defense. Therefore, the supreme court's assertion that the statute did not require a showing of intent was necessary to its holding and was not dictum. See State v. Misquadace, 629 N.W.2d 487, 490 n. 2 (Minn.App.2001) (“Dictum is a statement in an opinion that could have been eliminated without impairing the result of the opinion.”), aff'd, 644 N.W.2d 65 (Minn.2002).
