OPINION
DIETZEN, Justice.
This case requires us to decide what information the court should consider in determining whether the crime exception to the marital privilege statute in Minn. Stat. § 595.02, subd. 1(a) (2010), applies to the charged offense of disorderly conduct. Appellant Thomas Zais (Zais) was charged, in part, with the offense of disorderly conduct based on a November 15, 2009, incident. Before trial, Zais moved to exclude the proposed testimony of his wife on the ground that it was barred by the marital privilege. The district court concluded that the crime exception to the marital privilege did not apply to the charged offense of disorderly conduct, and therefore [35]*35his wife was barred from testifying against Zais without his consent. The State appealed the pretrial order, and the court of appeals reversed and remanded. We granted review on the issue of whether the crime exception to the marital privilege applies to the charged offense of disorderly conduct. Because the conduct underlying Zais’s charged offense of disorderly conduct was directed at his wife, we conclude that the crime exception to the marital privilege applies. We therefore affirm the court of appeals.
The material facts are undisputed. The charges against Zais arose out of an incident at the Zaises’ home on November 15, 2009. On the previous evening, police responded to a call from Zais’s wife after Zais had pushed their daughter. Based on their investigation, the police told Zais’s wife that Zais’s conduct did not support a criminal charge. Following this incident, Zais left the house for the night, and his wife removed the garage door opener from Zais’s truck so he could not reenter the house. According to his wife, Zais called the next afternoon and threatened to break into the house or “do whatever he had to to get in.”
Around 6:30 p.m. on November 15, Zais’s wife reported to the police that Zais was in their driveway in his pickup truck and was trying to break down the garage door. She stated that Zais had been drinking. Upon arrival, one officer saw a truck in the driveway and Zais standing by the garage door. Zais stated that his wife would not let him in the house, so he “knocked out some panels in the garage door” with a hook. Zais admitted that he had been drinking that afternoon. The officer administered field sobriety tests, which Zais failed. A preliminary breath test indicated that Zais had an alcohol concentration of .31, and a blood test later revealed Zais had an alcohol concentration of .23.
The State charged Zais with second-and third-degree DWI, Minn.Stat. §§ 169A.20, subds. 1(1) and 1(5) (2010), 169A.25 (2010), 169A.26 (2010); obstruction of legal process or arrest, Minn.Stat. § 609.50, subd. 1(2) (2010); careless driving, Minn.Stat. § 169.13, subd. 2 (2010); and disorderly conduct, MinmStat. § 609.72, subd. 1(3) (2010). Before trial, the State notified Zais that his wife was a proposed witness in the proceeding, and Zais moved to exclude her testimony based on the marital privilege in Minn.Stat. § 595.02, subd. 1(a). Following argument of the parties, the district court ruled that disorderly conduct “does not create a personal injury sufficient to destroy the spousal privilege,” and therefore Zais’s wife was prohibited from testifying against Zais without his consent. The State appealed.
In a published opinion, the court of appeals reversed and remanded, concluding that the State had established that the exclusion of the testimony of Zais’s wife had a critical impact on its ability to prosecute Zais, and that the crime exception to the marital privilege in section 595.02, subdivision 1(a), applies to a prosecution for disorderly conduct if the underlying conduct “was directed at and adversely affected or endangered” the other spouse. State v. Zais, 790 N.W.2d 853, 857-64 (Minn.App.2010). Subsequently, we granted review on the issue of whether the crime exception to the marital privilege applies to the charged offense of disorderly conduct.
I.
The State may appeal pretrial orders of the district court when the State can show that “the district court’s alleged error, unless reversed, will have a critical impact on the outcome of the trial.” Minn. [36]*36R.Crim. P. 28.04, subd. 2. The State has the burden of showing “clearly and unequivocally (1) that the district court’s ruling was erroneous and (2) that the ruling will have a ‘critical impact’ on the State’s ability to prosecute the case.” State v. Underdahl, 767 N.W.2d 677, 683 (Minn.2009) (citing State v. McLeod, 705 N.W.2d 776, 784 (Minn.2005)).
When a district court’s order excludes evidence in a criminal prosecution, the State need not show that the exclusion destroys its case; rather, the State need only demonstrate that “excluding the evidence ‘significantly reduces the likelihood of a successful prosecution.’ ” McLeod, 705 N.W.2d at 784 (quoting State v. Joon Kyu Kim, 398 N.W.2d 544, 551 (Minn.1987)). Moreover, the exclusion of evidence need not affect all charges against the defendant. It is enough if the exclusion affects the State’s ability to prosecute a specific charge. See Underdahl, 767 N.W.2d at 684 (noting that “an order that dismisses DWI charges, even when other charges remain, will have a critical impact on the prosecution’s case”); State v. Hicks, 301 Minn. 350, 352-53, 222 N.W.2d 345, 347 (1974) (concluding that an order preventing the chance of a successful prosecution on one charge was sufficient to allow an appeal even though the other charges were not affected). Finally, we consider the State’s evidence as a whole when determining if the exclusion of evidence will reduce the likelihood of a successful prosecution, and generally, “unique” evidence is “more likely to meet the critical impact test.” In re Welfare of L.E.P., 594 N.W.2d 163, 168 (Minn.1999).
We conclude that excluding the testimony of Zais’s wife would significantly reduce the State’s ability to prosecute Zais for disorderly conduct. The elements of disorderly conduct include that a person engaged in certain conduct “knowing, or having reasonable grounds to know that it will, or will tend to, alarm, anger or disturb others.” Minn.Stat. § 609.72, subd. 1 (2010). Zais’s wife was the only eyewitness to Zais’s conduct, and her testimony bears directly on whether the State can establish the elements of disorderly conduct. Without the testimony of Zais’s wife, it will be much more difficult for the State to prove the element of disorderly conduct that Zais either knew or had reason to know that his conduct of breaking the panels of the garage door to enter the home would alarm, anger, or disturb another. See id. Consequently, we conclude that the critical impact test is met.
II.
Zais argues that the crime exception to the marital privilege does not apply to the charged offense of disorderly conduct, and as a result, his wife may not testify against him. According to Zais, the crime exception does not apply because disorderly conduct is not a “crime committed by one [spouse] against the other.”

II.
Zais argues that the crime exception to the marital privilege does not apply to the charged offense of disorderly conduct, and as a result, his wife may not testify against him. According to Zais, the crime exception does not apply because disorderly conduct is not a “crime committed by one [spouse] against the other.”
We review evidentiary rulings by a district court regarding the availability of a privilege established by statutory or common law for an abuse of discretion. State v. Gianakos, 644 N.W.2d 409, 415 (Minn.2002). But the initial determination of whether a particular testimonial privilege or exception exists as a matter of law is a question that we review de novo. Id. Statutory construction is also a question of law that we review de novo. Zurich Am. Ins. Co. v. Bjelland, 710 N.W.2d 64, 68 (Minn.2006) (citing Am. Nat’l Gen. Ins. Co. v. Solum, 641 N.W.2d 891, 895 (Minn.2002)).
A.
To answer the question presented, we first examine the scope of the marital privilege, and then determine the applicability [37]*37of the crime exception to the facts of this case. The marital privilege has its roots in common law, and it has been part of the statutes of Minnesota since at least 1851. See Rev. Stat. Terr. Minn. ch. 95, § 58 (1851); Gianakos, 644 N.W.2d at 415.
The marital privilege statute provides:
A husband cannot be examined for or against his wife without her consent, nor a wife for or against her husband without his consent, nor can either, during the marriage or afterwards, without the consent of the other, be examined as to any communication made by one to the other during the marriage.[1]
Minn.Stat. § 595.02, subd. 1(a) (footnote added). The statute also contains several exceptions to the marital privilege, including the crime exception. This exception provides that the marital privilege “does not apply to ... a criminal action or proceeding for a crime committed by one against the other.” Id.
In Huot v. Wise, we held that the language of the marital privilege statute, and not the scope of the common law marital privilege, determined whether one spouse could testify against the other.2 27 Minn. 68, 69-70, 6 N.W. 425, 426 (1880). In Huot, we considered whether the wife was a competent witness for the defendant in a civil action brought by her husband. Id. at 69, 6 N.W. at 425. We examined the marital privilege, concluding that the inclusion of specific exceptions to the statute “excludes resort to the common law to determine how far the rule shall prevail, and what cases shall be excepted from it.” Id. at 69-70, 6 N.W. at 426. As such, “it is immaterial that the common law did or did not ... admit the evidence of a wife against her husband, in a case like this.” Id. at 70, 6 N.W. at 426. We concluded that the wife’s testimony was not admissible because the circumstances were not within an exception to the statute. Id. at 70, 6 N.W. at 426. Under Huot, we must look to the language of the marital privilege statute to determine whether the crime exception would allow a spouse to testify against his or her spouse who has been charged with disorderly conduct.
B.
We must next determine whether, under the facts of this case, the crime of disor[38]*38derly conduct is a crime committed by one spouse against the other spouse. Zais argues that the applicability of the crime exception to a particular crime should be determined solely by the elements of the crime. The State counters that the court must examine the underlying conduct that the defendant is alleged to have committed to determine whether the crime exception is applicable.
The applicability of a statute to undisputed facts is a question of law for the court that requires construction of the statute. See City of Morris v. Sax Invs., Inc., 749 N.W.2d 1, 5 (Minn.2008). The goal of all statutory construction is to effectuate the intent of the Legislature. Minn.Stat. § 645.16 (2010). In construing the language of a statute, we give words and phrases their plain and ordinary meaning. Minn.Stat. § 645.08(1) (2010); Amaral v. Saint Cloud Hosp., 598 N.W.2d 379, 384 (Minn.1999). Thus, if the language of a statute is clear and free from ambiguity, our role is to apply the language of the statute, and not explore the spirit or purpose of the law. Minn.Stat. § 645.16. A statute is ambiguous if it is susceptible to more than one reasonable interpretation. Am. Family Ins. Grp. v. Schroedl, 616 N.W.2d 273, 277 (Minn.2000). Generally, the marital privilege is construed narrowly and the exceptions are construed broadly. See Larson v. Montpetit, 275 Minn. 394, 402, 147 N.W.2d 580, 586 (1966).
The crime exception provides that one spouse may testify in “a criminal action or proceeding for a crime committed by one [spouse] against the other.” Minn.Stat. § 595.02, subd. 1(a). Previously, we have applied the crime exception, but in those cases, the application of the crime exception was largely undisputed. See, e.g., State v. Cram, 718 N.W.2d 898, 904 n. 2 (Minn.2006) (concluding that in a prosecution of a husband for the murder of his wife, statements made by the wife to the husband were admissible). Moreover, early cases did not address whether the court should review the elements of the crime, the underlying conduct, or both, to determine whether the crime exception applies. See Armstrong, 4 Minn, at 342-43 (Gil. at 258-59).
It is undisputed that the prosecution of Zais for the charged offense of disorderly conduct satisfies the requirement of “a criminal action or proceeding.”3 The crux of the dispute turns on what information the court should consider in determining whether the crime exception to the marital privilege statute in section 595.02, subdivision 1(a), applies to the charged offense of disorderly conduct.
We conclude that the crime exception to the marital privilege statute in section 595.02, subdivision 1(a), is not ambiguous, and requires that the court examine not only the elements of the crime, but also the underlying conduct of the defendant to determine whether the crime was “committed” by one spouse against the other. The word “committed” broadly refers to acts or conduct done by one spouse against the other spouse. See The American Heritage Dictionary of the English Language 371 (4th ed.2000) (defining “commit” as “[t]o do, perform, or perpetrate”). The plain language of the statute contemplates that the court consider all relevant underlying facts to make that de[39]*39termination. Because few, if any, crimes have as an element that certain conduct be directed at a spouse, the relevant underlying facts must be considered to determine if a crime was committed against the defendant’s spouse. Had the Legislature intended to limit the court’s analysis to examining only the elements of the crime in the abstract, it could have easily done so by including specific limiting language to that effect.
Our conclusion is also consistent with other cases in which we have interpreted the meaning of crimes committed “against a person.” In State v. Nunn, we considered the meaning of a felony-murder requirement that the underlying felony must have been “upon or affecting the person whose death was caused.” 297 N.W.2d 752, 753 (Minn.1980). We concluded that to evaluate whether a felony was “upon or affecting” a person and posed a “special danger to human life,” the preferred approach was to consider “not just the elements of the felony in the abstract but the facts of the particular case and the circumstances under which the felony was committed.” Id. at 754.
Similarly, in State v. Notch, we considered the meaning of “crime against a person” under a sentencing guidelines provision allowing permissive consecutive sentencing when “the offender is convicted of multiple current felony convictions for crimes against different persons.” 446 N.W.2d 383, 385 (Minn.1989). We concluded that a crime is against the person “if, as committed, it is a crime against the person.” Id. Thus, a court could evaluate the underlying conduct of the felony to determine whether it was a crime against a person. Id.; see also State v. Myers, 627 N.W.2d 58, 62-63 (Minn.2001) (concluding that obstructing legal process could be a crime against a person, pursuant to the sentencing guidelines, if the defendant’s underlying conduct in committing the offense “poses a special danger to human life”).
Accordingly, we conclude that the crime exception to the marital privilege contemplates that the court must examine not only the elements of the crime charged, but also the underlying conduct supporting the crime to determine whether the crime charged was “committed by one [spouse] against the other.”
C.
Zais also argues that the charged offense of disorderly conduct cannot be considered a crime committed by one spouse against the other because it is a public offense committed against the public at large and not a specific individual. According to Zais, the crime exception only applies to crimes directed at a person, such as assault or domestic violence. The State counters that the conduct supporting the disorderly conduct charge may be committed by one spouse against the other, and therefore the crime exception applies.
To answer this question, we must examine the statutory requirements for the charged offense of disorderly conduct. Minnesota Statutes § 609.72, subd. 1(3), provides, in relevant part, that a person commits disorderly conduct if he or she:
knowing, or having reasonable grounds to know that it will, or will tend to, alarm, anger or disturb others ... (3) engages in offensive, obscene, abusive, boisterous, or noisy conduct or in offensive, obscene, or abusive language tending reasonably to arouse alarm, anger, or resentment in others.
The statute does not require that “others” are actually affected, but does contemplate that such a result could occur as a consequence of the disorderly conduct [40]*40itself.4 The disorderly conduct statute also indicates that the crime may be committed “in a public or private place.”5 Id.
Moreover, the crime may be committed when there is only one witness to the defendant’s conduct. See City of Saint Paul v. Azzone, 287 Minn. 136, 140-41, 177 N.W.2d 559, 562 (1970); State v. Reynolds, 243 Minn. 196, 202, 66 N.W.2d 886, 891 (1954). In Reynolds, we held that the disorderly conduct statute, Minn.Stat. § 615.17 (1953), was constitutional and not void for vagueness. 243 Minn. at 198-99, 66 N.W.2d at 888-89. In doing so, we stated:
If the statute does not require that the act be committed in a public place or a specified place, then it is sufficient if the act is committed within the confines of the jurisdiction of the court, and, dependent upon the circumstances, it may be enough if the peace of only one person is disturbed.
Id. at 202, 66 N.W.2d at 891. And in Azzone, we sustained convictions for disorderly conduct in violation of Saint Paul Legislative Code § 438.02 (1970), when the conduct was directed toward a police officer and not observed by the public. 287 Minn. at 140-41, 177 N.W.2d at 562.
We conclude that the crime exception to the marital privilege applies to the charged offense of disorderly conduct when the alleged conduct is committed by one spouse against the other spouse. The disorderly conduct statute does not exclude conduct that is directed against one person. Consequently, we conclude that the crime exception may be applicable to the charged offense of disorderly conduct in this case.6
D.
Finally, we consider whether the State’s proposed evidence7 regarding the [41]*41elements of the disorderly conduct charge, together with Zais’s actual conduct, establish that the crime was committed by one spouse against the other. The district court examined the elements of disorderly conduct, but not the underlying conduct of the defendant, and therefore applied the wrong legal test. Instead, a district court should examine the elements of the offense together with the defendant-spouse’s underlying conduct to determine whether the record establishes that the defendant-spouse’s acts were done against the other spouse. If so, the offense of disorderly conduct was committed by one spouse against the other.
The State’s proposed evidence establishes that there was a domestic dispute at Zais’s home the night before the incident in question, during which Zais pushed his daughter and his wife called the police. When Zais left the house in a friend’s car, his wife took the garage door opener out of Zais’s truck so he would not be able to reenter the home. The next day, Zais called his wife and “threatened to break into the house or do whatever he had to to get in.” When Zais appeared at the house after he threatened to break in and began breaking the garage door, Zais’s wife immediately called 911. She also heard Zais banging on the garage door. The police saw that panels had been broken out of the garage door, and Zais told an officer his wife would not let him back inside the house and that he broke the garage door panels with a hook to get inside the house.
Based upon the proposed evidence the State has established that Zais committed the offense of disorderly conduct against his wife. Zais’s conduct was done against and directed at his wife.8 He engaged in “abusive, boisterous, or noisy conduct” by banging on and breaking off several panels of his garage door at a time when his wife was home.9 See Minn. § 609.72, subd. 1(3). And Zais forcibly tried to enter the home shortly after making threatening comments to his wife. Specifically, Zais broke the panels of the garage door to gain access to the house knowing, or having reason to know, that doing so would alarm, anger, or disturb another — his wife.10 See id. Accordingly, we conclude that the crime exception to the marital privilege is applicable to the disorderly conduct charge against Zais. Therefore, we hold that Zais’s wife may testify against Zais on the disorderly conduct charge.
Affirmed.
