OPINION
ANDERSON, Justice.
An arbitrator issued an award against appellants Sining Mao, Western Digital Corporation, and Western Digital Technologies, Inc., in an amount exceeding $500 million. The award was vacated in part by the district court and then reinstated by the court of appeals. Mao and the Western Digital entities now separately seek review of the reinstatement decision. Mao and Western Digital argue that the arbitrator’s punitive sanctions, which precluded any evidence or defense and en[754]*754tered a judgment of liability on certain claims, must be vacated under Minn.Stat. § 572.19, subd. 1(3)-(4) (2010),1 because the arbitrator exceeded his authority by issuing these sanctions and substantially prejudiced Mao and Western Digital by refusing to hear evidence material to the controversy. Because we conclude that the arbitrator did not exceed his authority or refuse to hear material evidence as required for vacatur under Minn.Stat. § 572.19, subd. 1(3)-(4), we affirm the decision of the court of appeals reinstating the arbitration award in full.
The arbitration agreement at issue arose out of an employment contract between Mao and his former employer, respondent Seagate Technology, LLC. Sea-gate designs and manufactures hard disk drives for computers. In his role as senior director for advanced head concepts at Seagate, Mao worked on technology that involves incorporating tunneling magneto-resistance (TMR) into read heads,2 which, if done successfully, would allow for vastly improved storage capacity on hard disk drives.
When Mao began working for Seagate, he signed an employment agreement stating, among other requirements, that if he left Seagate, he would preserve the confidentiality of all trade secrets, return all company documents, and not solicit any current Seagate employees for other employment using unfair or deceptive means. The employment agreement also contained the following arbitration clause:
Arbitration: Except as stated below, I agree that any dispute or controversy arising out of or relating to any interpretation, construction, performance or breach of this Agreement, shall be settled by arbitration to be held in Henne-pin County, Minnesota, in accordance with the rules then in effect of the American Arbitration Association. The arbitrator may grant injunctions or other relief in such dispute or controversy. The decision of the arbitrator shall be final, conclusive and binding on the parties to the arbitration. Judgment may be entered on the arbitrator’s decision in any court having jurisdiction. The Company and I shall each pay one-half of the costs and expenses of such arbitration, and each of us shall separately pay our counsel fees and expenses.
Mao left Seagate in September 2006 and joined Seagate’s competitor, Western Digital Corporation, in October 2006. After Mao joined Western Digital, Seagate commenced a district court action seeking in-junctive relief to prevent the disclosure of Seagate’s trade secrets and later amended its claim to allege actual misappropriation of trade secrets. Seagate’s primary allegation, in essence, was that Mao stole Sea-gate’s trade secrets and confidential information regarding TMR technology and provided it to Western Digital, which [755]*755Western Digital then used to design and manufacture a TMR read head. Specifically, Seagate made: (1) claims against Mao and Western Digital for the misappropriation of eight trade secrets; (2) claims against Mao for breach of contract, breach of fiduciary duty, and breach of loyalty; and (3) a claim against Western Digital for tortious interference with contract.
Western Digital invoked the arbitration clause of the employment agreement, and the district court stayed the lawsuit pending arbitration. Before the arbitration hearing began, Seagate brought a motion for sanctions against Western Digital and Mao based on alleged fabrication of evidence.3 The fabrication related to documents submitted by Western Digital and Mao, which were intended to prove that three of Seagate’s claimed trade secrets, referred to as Trade Secrets 4-6, had been publicly disclosed before Mao left Seagate. Seagate alleged that Mao had inserted additional PowerPoint slides containing information on Trade Secrets 4-6 into his copy of a presentation that he had given at a conference while employed by Seagate to make it appear as if this information had been presented in public, and therefore did not qualify as trade secrets.
In the motion for sanctions based on fabrication, Seagate requested “a sanction commensurate with the severity of the misconduct.” Specifically, Seagate requested an order precluding Western Digital and Mao “from presenting any defense to the trade secret misappropriation claims asserted against them, including barring [Western Digital and Mao] from (1) disputing the validity and misappropriation of any of Seagate’s eight asserted trade secrets, and (2) disputing Western Digital’s use of Seagate’s eight asserted trade secrets.” Seagate also requested compensation for “the costs and attorneys’ fees it was forced to incur to investigate and expose the document fabrication and to bring this motion to remedy it.” Western Digital and Mao responded by requesting sanctions against Seagate to “compensate the Claimants for the unnecessary fees and costs incurred in defending against Sea-gate’s frivolous charges.” Western Digital and Mao also asked the arbitrator to defer consideration of the sanctions motions until after the arbitrator had heard evidence “in the context of the full arbitration hearing,” and the arbitrator granted this latter request.
The arbitration hearing was held over 34 days in 2011. The arbitrator found in favor of Mao and Western Digital with respect to claims arising Out of Trade Secrets 1-3 and 7-8, concluding that Seagate had failed to prove that the information reflected in these claims met the definition of a trade secret.4 Trade Secrets 4-6 were addressed separately, as the arbitrator first reviewed the motion for sanctions based on fabrication • and determined that Mao fabricated the disputed slides for the purpose of litigation while working at Western Digital. The arbitrator stated: “The fabrications were obvious. There is no question that Western Digital had to know of the fabrications and yet continued to represent to the Arbitrator that Dr. Mao did in fact insert the disputed slides ... at the time of the conferences.” The arbitrator concluded that “Dr. Mao’s fabrication of evidence and Western Digital’s complicity by submitting the obviously fabricated evidence to the Arbitrator is an [756]*756egregious form of litigation misconduct and warrants severe sanctions.” The arbitrator then cited Harris Trust & Savings Bank v. Ali, 100 Ill.App.3d 1, 55 Ill.Dec. 186, 425 N.E.2d 1359, 1366 (1981), which states that “[w]hen evidence is ... fabricated, a presumption arises that the cause of action or the defense it was intended to support is without substantial foundation.” (citation omitted) (internal quotation marks omitted). The arbitrator imposed the following sanctions against Western Digital and Mao:
a) Preclusion of any evidence or defense by Western Digital and Dr. Mao disputing the validity of Seagate’s asserted trade secrets 4, 5, and 6;
b) Preclusion of any evidence or defense by Western Digital and Dr. Mao regarding misappropriation by Western Digital and Dr. Mao of Seagate’s asserted trade secrets 4, 5, and 6;
c) Preclusion of any evidence or defense by Western Digital disputing that it has used or is using Seagate’s asserted trade secrets 4, 5, and 6 in Western Digital’s manufactured TMR read heads; and
d) Entry of judgment against Western Digital and Dr. Mao of liability for misappropriation and use of Sea-gate’s asserted trade secrets 4, 5, and 6.
After determining that Seagate had established that Trade Secrets 4-6 qualified as trade secrets and, consistent with the sanctions, that these trade secrets had been improperly used by Western Digital, the arbitrator found in favor of Seagate on its claims arising out of Trade Secrets 4-6. The arbitrator also found that Mao’s testimony, in part due to the fabrication of evidence, lacked credibility and that Mao had breached his employment contract by disclosing confidential information, not returning company documents, and soliciting a Seagate employee for employment at Western Digital. The arbitrator calculated damages based on “the unjust enrichment method,” awarding Seagate compensatory damages of $525 million, prejudgment interest totaling nearly $96 million, and post-award interest. The arbitrator determined that Western Digital and Mao are jointly and severally liable for the damages.
Western Digital and Mao brought a motion in Hennepin County District Court to vacate the portion of the arbitration award concerning Trade Secrets 4-6, and Sea-gate moved to confirm the entire award. Following a hearing, the district court issued an order confirming the award in part, vacating the award in part, and ordering a rehearing before a new'arbitrator. The district court determined that the arbitrator’s ability to impose sanctions was determined by the arbitration agreement, and that the agreement in this case did not contain provisions that could be interpreted as authorizing sanctions beyond attorney fees. Furthermore, the district court determined that even if sanctions had been permitted, the arbitrator misapplied sanctions law by not allowing Western Digital and Mao to rebut the presumption created by the fabricated evidence that their defense was without substantial foundation. Thus, the district court concluded that the arbitrator exceeded his authority by issuing punitive sanctions against Western Digital and Mao, and so vacatur of the portion of the award impacted by the sanctions was appropriate under Minn.Stat. § 572.19, subd. 1(3). The district court also concluded that by disregarding material evidence when fashioning the award, the arbitrator substantially prejudiced Western Digital and Mao by “refusing] to hear evidence material to the controversy,” and so Minn.Stat. § 572.19, subd. 1(4), also required vacatur.
[757]*757Therefore, the district court vacated the portion of the award regarding Trade Secrets 4-6, confirmed the award regarding the other claims, and ordered that the matter be reheard before a new arbitrator.
Seagate appealed, arguing that the district court erred by: (1) determining that the arbitrator had exceeded his authority by issuing sanctions and concluding that Western Digital and Mao had not waived their right to challenge the sanctions; (2) reviewing the merits of the arbitrator’s decision to impose sanctions; (3) granting vacatur based on public policy; and (4) ordering a rehearing before a new arbitrator. The court of appeals granted discretionary review, then reversed and remanded for entry of an order confirming the award and judgment entered on that order. Seagate Tech., LLC v. W. Digital Corp., 834 N.W.2d 555, 567 (Minn.App.2013). The court of appeals applied a method of waiver analysis from the Eighth Circuit, which holds that there is a waiver if the party did not object during the arbitration and that party asked the arbitrator to use a power similar to the power they now challenge. Id. at 561-62; see Wells Fargo Bank, N.A. v. WMR e-PIN, LLC, 653 F.3d 702, 711-12 (8th Cir.2011). Using this Eighth Circuit method, the court of appeals concluded that Western Digital and Mao had waived their right to challenge the arbitrator’s ability to issue punitive sanctions. Seagate Tech., 834 N.W.2d at 561-62.
Although the court of appeals stated that its finding of waiver “is dispositive of the issue of arbitrator authority and could end our analysis,” it nonetheless reviewed the merits of the arbitrator’s use of punitive sanctions and the district court’s order for a rehearing before a new arbitrator. Id. at 562. The court of appeals concluded that a broadly worded arbitration agreement confers inherent authority on the arbitrator to impose punitive sanctions, that the arbitrator’s possible misapplication of sanctions law did not compel vaca-tur, that the arbitration award did not violate public policy, and that the district court abused its discretion by directing a rehearing before a new arbitrator. Id. at 564-67. We granted Western Digital and Mao’s request for further review.
I.
Before evaluating if the arbitrator imposed permissible sanctions on Western Digital and Mao, we must determine if Western Digital and Mao waived their right to request vacatur under Minn. Stat. § 572.19, subd. 1(3)-(4) (2010). We review a district court’s determination of waiver for clear error, In re Civil Commitment of Giem, 742 N.W.2d 422, 432 (Minn.2007), but we review the interpretation of a statute de novo, Krueger v. Zeman Constr. Co., 781 N.W.2d 858, 861 (Minn.2010).
The grounds for Western Digital and Mao’s challenges to the arbitration award are statutory. Therefore, although other jurisdictions have developed various methods for analyzing waiver in the context of an arbitration, the necessity of an objection before requesting vacatur under Minn.Stat. § 572.19, subd. 1, is controlled first by the language of the statute.5 Subdivision 1 provides in relevant part:
[758]*758Upon application of a party, the court shall vacate an award where:
(1) The award was procured by corruption, fraud or other undue means;
(2) There was evident partiality by an arbitrator appointed as a neutral or corruption in any of the arbitrators or misconduct prejudicing the rights of any party;
(3) The arbitrators exceeded their powers;
(4) The arbitrators refused to postpone the hearing upon sufficient cause being shown therefor or refused to hear evidence material to the controversy or otherwise so conducted the hearing, contrary to the provisions of section 572.12, as to prejudice substantially the rights of a party; or
(5)There was no arbitration agreement and the issue was not adversely determined in proceedings under section 572.09 and the party did not participate in the arbitration hearing without raising the objection.
Western Digital and Mao challenge the arbitration award on the basis of subdivision 1(3), alleging that the arbitrator exceeded his authority, and subdivision 1(4), alleging that the arbitrator refused to hear material evidence. They note that while subdivision 1(5) requires that “the party did not participate in the arbitration hearing without raising the objection,” subdivisions 1(3) and (4) do not contain any similar limiting language.
We agree that this distinction is significant. We construe a statute “as a [759]*759whole so as to harmonize and give effect to all its parts, and where possible, no word, phrase, or sentence will be held superfluous, void, or insignificant.” Jackson v. Mortg. Elec. Registration Sys., Inc., 770 N.W.2d 487, 496 (Minn.2009) (citation omitted) (internal quotation marks omitted); see also Minn.Stat. § 645.16 (2012) (“Every law shall be construed, if possible, to give effect to all its provisions.”). Here, if the Legislature had intended for all clauses of Minn.Stat. § 572.19, subd. 1, to-implicitly require an objection, the explicit requirement of an objection in subdivision 1(5) would be superfluous. Moreover, “distinctions in language in the same context are presumed to be intentional,” In re Stadsvold, 754 N.W.2d 323, 328-29 (Minn.2008), so a condition expressly mentioned in one clause of a subdivision provides evidence that the Legislature did not intend for the condition to apply to other clauses in which the condition is not stated. In addition, “[w]e cannot add words or meaning to a statute that were intentionally or inadvertently omitted.” Rohmiller v. Hart, 811 N.W.2d 585, 590 (Minn.2012). Therefore, we cannot conclude that subdivision 1(3)-(4) requires an objection during arbitration when, as evidenced by difference in the language between these clauses and subdivision 1(5), the Legislature appears to have intentionally omitted such a requirement.
Our case law also supports this reasoning. In Twomey v. Durkee, we held that the plaintiffs were estopped from challenging the arbitrability of a dispute because they had participated in the arbitration proceedings without objection. 291 N.W.2d 696, 699 (Minn.1980). Twomey recognized that Minn.Stat. § 572.19, subd. 1, requires an objection for challenges brought under subdivision 1(5). But in Twomey we also stated that claims based on a violation of Minn.Stat. § 572.19, subd. 1(4), or other clauses of subdivision 1, “except those relating to arbitrability,” are “not affected by a finding of estoppel” based on the failure to object. 291 N.W.2d at 699. Twomey clearly distinguishes between the necessity of an objection under subdivision 1(5), which involves arbitrability, and the other clauses of section 572.19, subdivision 1, which do not. This distinction is in line with our statutory analysis, suggesting that while subdivision 1(5) claims can be subject to estoppel based on a failure to object, challenges raised under the other clauses of section 572.19, subdivision 1 are not similarly vulnerable to the absence of an objection.
In addition to the statutory analysis, the structure of arbitration proceedings supports this result. Given the very limited appeal rights, the absence of a transcript in many informal arbitration proceedings, and the use of nonlawyers as arbitrators in some arbitration hearings, the imposition of an objection requirement by our court when the Legislature did not do so would be an awkward fit at best. See, e.g., Larson v. Nygaard, 148 Minn. 104, 107-08, 180 N.W. 1002, 1003 (1921) (discussing an arbitration in which the arbitrators did not have legal training, all proceedings were oral, no attorneys or advisors could participate, and “[a]ll technicalities were to be disregarded”).
Based on this analysis, we conclude that under Minn.Stat. § 572.19, subd. 1, an objection during arbitration is required only for challenges brought under subdivision 1(5) and is not required for challenges brought under the other clauses of that subdivision. We accordingly reject the court of appeals’ use of the Eighth Circuit method of waiver analysis for this provision, which would find waiver whenever a party failed to object during the arbitration and invoked the same power during arbitration that the party now challenges on appeal. See Wells Fargo Bank, 653 F.3d at 711-12. Although Seagate makes [760]*760several policy-based arguments in favor of the Eighth Circuit approach, such considerations cannot outweigh the plain language of the statute. See Minn.Stat. § 645.08, subd. 1 (2012) (stating that when interpreting statutes, “words and phrases are construed ... according to their common and approved usage”).
We hold that Western Digital and Mao did not waive their right to challenge the arbitration award on the basis of Minn. Stat. § 572.19, subd. 1(3)-(4).
II.
Having concluded that Western Digital and Mao did not waive their right to challenge the arbitration award under Minn. Stat. § 572.19, subd. 1(3)-(4), we must now review the merits of these challenges.
A.
We first examine whether the arbitrator had the authority to impose punitive sanctions that precluded any evidence or defense on certain issues and entered a judgment of liability. Western Digital and Mao contend that by issuing these sanctions, the arbitrator exceeded his authority. Accordingly, they request vacatur under Minn.Stat. § 572.19, subd. 1(3), of the portion of the award impacted by the sanctions. The authority of an arbitrator to impose punitive sanctions, which for purposes of this opinion refers to sanctions stemming from party misconduct,6 is an issue of first impression in Minnesota. Courts in other jurisdictions are divided not only on the proper result, but also on the method of analysis.7
We determine the scope of an arbitrator’s authority de novo. Cnty. of Hennepin v. Law Enforcement Labor Servs., Inc., Local No. 19, 527 N.W.2d 821, 824 (Minn.1995). An arbitration award “will be set aside by the courts only when [761]*761the objecting party meets its burden of proof that the arbitrators have clearly exceeded the powers granted to them in the arbitration agreement; courts will not overturn an award merely because they may disagree with the arbitrators’ decision on the merits.” Children’s Hosp., Inc. v. Minn. Nurses Ass’n, 265 N.W.2d 649, 652 (Minn.1978) (emphasis added); see also State v. Minn. Ass’n of Profl Emps., 504 N.W.2d 751, 755-56 (Minn.1993) (“In evaluating challenges to the scope of an arbitrator’s powers, this court’s scope of review is very limited.... ”). In our review of an arbitrator’s authority, “[e]very reasonable presumption is exercised in favor of the finality and validity of the award.” Nat’l Indem. Co. v. Farm Bureau Mut. Ins. Co., 348 N.W.2d 748, 750 (Minn.1984).
The arbitrator’s ability to issue punitive sanctions is controlled by the arbitration agreement. Law Enforcement Labor Servs., 527 N.W.2d at 824 (“The scope of an arbitrator’s authority is a matter of contract interpretation to be determined from a reading of the parties’ arbitration agreement.”). Therefore, parties are able to include or exclude the use of punitive sanctions when constructing an arbitration agreement, either through express provision or through the incorporation of a particular set of arbitration rules.8 When reviewing an arbitration agreement to determine the scope of an arbitrator’s authority, we use principles of contract interpretation. Children’s Hosp., 265 N.W.2d at 652. While courts possess inherent judicial powers that enable them to impose punitive sanctions, see Chambers v. NASCO, Inc., 501 U.S. 32, 44, 111 S.Ct. 2123, 115 L.Ed.2d 27 (1991), arbitrators have no correlating inherent authority and receive their powers from either the arbitration agreement, see Law Enforcement Labor Servs., 527 N.W.2d at 824, or the Legislature.9
Following principles of contract law, we begin by looking at the language of the agreement. Interpreting a contract requires us to “determine if the language is clear and unambiguous, meaning it has only one reasonable interpretation. If so, we give effect to the language of the [agreement].” Halla Nursery, Inc. v. City of Chanhassen, 781 N.W.2d 880, 884 (Minn.2010) (citation omitted). Seagate notes that we have often construed arbitration agreements broadly. See, e.g., Michael-Curry Cos. v. Knutson S’holders Liquidating Trust, 449 N.W.2d 139, 142 (Minn.1989); David Co. v. Jim W. Miller Constr., Inc., 444 N.W.2d 836, 842 (Minn.1989). But we cannot convey broader powers than the words of the arbitration agreement provide under their ordinary meaning. See Halla Nursery, 781 N.W.2d at 884-85 (rejecting an interpretation that “directly contradicts the plain terms” of a contract). Although Seagate argues that the arbitrator is empowered to interpret his authority on the basis of the agreement and to impose any award that does not manifestly disregard the spirit of the [762]*762agreement,10 the arbitrator cannot expand his authority beyond what could reasonably be interpreted from the arbitration agreement.
The arbitration agreement empowered the arbitrator to settle “any dispute or controversy arising out of or relating to any interpretation, construction, performance or breach” of the employment agreement, and the agreement states that “[t]he arbitrator may grant injunctions or other relief in such dispute or controversy.” The agreement also says that the arbitration will be conducted in accordance with the “the rules then in effect of the American Arbitration Association.” The American Arbitration Association Employment Arbitration Rules and Mediation Procedures (AAA Employment Rules) do not specifically address punitive sanctions, but they do authorize arbitrators to “grant any remedy or relief that would have been available to the parties had the matter been heard in court including awards of attorney’s fees and costs.” AAA Employment R. 39(d) (2009).
We must determine, therefore, whether the power to grant “injunctions or other relief’ or “any remedy or relief that would have been available to the parties had the matter been heard in court” includes the power to impose punitive sanctions. Western Digital argues that punitive sanctions are neither a remedy nor a form of relief. Western Digital distinguishes between sanctions issued to punish a party after misconduct, which it labels “punitive sanctions,” and sanctions intended to remedy a harm caused to one party, which it labels “remedial sanctions.” Thus, Western Digital argues that while remedial sanctions, being a form of remedy, are permitted under the parties’ arbitration agreement, the punitive sanctions issued here were outside the arbitrator’s authority because they did not serve as a remedy or relief to either party. Seagate argues that there is no distinction between punitive and remedial sanctions, but that even if there was, the term “relief’ is broad enough to encompass both.
We look first at the language in the arbitration agreement authorizing the arbitrator to “grant injunctions or other relief’ in “any dispute or controversy arising out of or relating to any interpretation, construction, performance or breach” of the employment agreement. “Relief’ is defined as “[t]he redress or benefit, especially] equitable in nature (such as an injunction or specific performance), that a party asks of a court.” Black’s Law Dictionary 1482 (10th ed.2014). Here, the punitive sanctions issued were requested by Seagate as a redress for the wrong committed by Western Digital and Mao when Mao fabricated evidence. In addition, although punitive sanctions are issued in large part to punish one party, because they also benefit the other party, they are appropriately categorized as a form of relief. The Legislature has also categorized punitive measures as a form of relief, such as when discussing the authority of an arbitrator to award “punitive damages or other exemplary relief.” Minn.Stat. § 572B.21(a) (2012) (emphasis added).11 [763]*763These sources confirm that punitive sanctions qualify as “injunctions or other relief’ as authorized by the arbitration agreement.
The sanctions issued were also authorized by the AAA Employment Rules, which were incorporated into the arbitration agreement and allow the arbitrator to grant “any remedy or relief that would have been available to the parties had the matter been heard in court including awards of attorney’s fees and costs.” AAA Employment R. 39(d). As we have established, punitive sanctions fall within the ordinary meaning of relief. Punitive sanctions can also be properly construed as a remedy. Remedy is defined as “[t]he means of enforcing a right or preventing or redressing a wrong; legal or equitable relief’ and “anything a court can do for a litigant who has been wronged or is about to be wronged.” Black’s Law Dictionary 1485 (10th ed.2014) (quoting Douglas Laycock, Modem American Remedies (14th ed.2010)). Here, the sanctions were issued in part to redress a wrong, the fabrication of evidence, which harmed Seagate during the arbitration. Thus, the sanctions constitute a remedy provided to Seagate.
Our conclusion that punitive sanctions are a remedy is also supported by case law. For example, in State v. Miller we equated a punitive sanction with a remedy, noting that a district court sanction excluding certain testimony was a “proper remedy” that “appropriately reflected] the seriousness of the ethical violation and the prejudice to appellant.” 600 N.W.2d 457, 468 (Minn.1999). Likewise, the Eighth Circuit has found dismissal to be an appropriate sanction “when there has been a clear record of delay or contumacious conduct by the plaintiff.” Bergstrom v. Frascone, 744 F.3d 571, 575 (8th Cir.2014) (citation omitted) (internal quotation marks omitted).12
Having established that the sanctions qualify as a “relief or remedy” for purposes of AAA Employment Rule 39(d), we next examine whether the sanctions issued also satisfy the second requirement set out in AAA Employment Rule 39(d). That requirement states that the relief or remedy would “have been available to the parties had the matter been heard in court.” The preclusion of evidence or any defense on an issue is a sanction used by courts. See, e.g., State v. Richards, 495 N.W.2d 187, 199 (Minn.1992) (noting that the “preclusion of evidence is a severe sanction”). This type of sanction has also been applied as a response to fabricated evidence. See, e.g., Aoude v. Mobil Oil Corp., 892 F.2d 1115, 1119 (1st Cir.1989) (“We find the caselaw fully consonant with the view that a federal district judge can order dismissal or default where a litigant has stooped to the level of fraud on the court.”); Vargas v. Peltz, 901 F.Supp. 1572, 1581 (S.D.Fla.1995) (“The federal case law is well established that dismissal is the appropriate sanction where a party manufactures evidence which purports to corroborate its substantive claims.”); Sun World, Inc. v. Lizarazu Olivarria, 144 F.R.D. 384, 391 (E.D.Cal.1992) (ordering the entry of de[764]*764fault judgment when defendant committed fraud on the court). Therefore, we conclude that the sanctions issued were of the type that would have been “available to the parties had the matter been heard in court,” and as such, they were authorized by AAA Employment Rule 39(d).
Western Digital argues that it did not act with a level of culpability to warrant punitive sanctions and that the arbitrator exceeded the level of authority given to a court to issue punitive sanctions. Likewise, Mao argues that the arbitrator exceeded his authority by not applying sanctions law in the same way that a Minnesota court would have. But the arbitration agreement did not specify that the remedies or relief must be awarded utilizing judicial principles or limitations; instead, the agreement broadly authorized the arbitrator to grant “injunctions or other relief.”13 In addition, although AAA Employment Rule 39(d) requires the relief to be one available to the parties in a court action, it does not require the arbitrator to employ the sanction using the same standards as any particular court. “Where the arbitrators are not restricted by the submission to decide according to principles of law, they may make an award according to their own notion of justice without regard to the law.” Metro. Waste Control Comm’n v. City of Minnetonka, 308 Minn. 385, 389, 242 N.W.2d 830, 832 (1976).
Furthermore, we have previously held that arbitrators have broad power to fashion remedies within the scope authorized by the language of the arbitration agreement. See David Co., 444 N.W.2d at 840 (allowing an arbitrator to fashion an equitable award instead of providing a monetary remedy). And we have recognized that “an award will not be vacated merely because the court may believe the arbitrators erred.” Id.; see also Minn.Stat. § 572.19, subd. 1 (“[T]he fact that the relief was such that it ... would not be granted by a court of law or equity is not ground for vacating or refusing to confirm the award.”). In addition, the AAA Employment Rules do not limit an arbitrator’s authority to forms of relief that would have been granted by a court; rather, Rule 39(d) references forms of relief that “would have been available” in a court. AAA Employment R. 39(d) (emphasis added). This language implies that while arbitrators may be limited to the types of relief available in a court, they are not limited in the manner of awarding these forms of relief by the same rules as a court would have been. Because punitive sanctions were a permissible form of relief and because the arbitrator had discretion in fashioning a remedy, we hold that the arbitrator did not clearly exceed his authority in violation of Minn.Stat. § 572.19, subd. 1(3), by issuing punitive sanctions against Western Digital and Mao.
[765]*765We recognize that entrusting an arbitrator with broad powers over forms of relief could theoretically lead to unfair results in arbitration. Certainly Mao and Western Digital, implicitly if not explicitly, argue that the award here was a result of an out-of-control arbitrator or was otherwise unjust.14 Some believe that arbitration has benefits, potentially including faster resolution and less expense than the judicial system as well as a high degree of confidentiality. Christopher R. Drahozal & Stephen J. Ware, Why Do Businesses Use (or Not Use) Arbitration Clauses?, 25 Ohio St. J. on Disp. Resol. 433, 451-52 (2010). But the benefits come with costs, including significantly less oversight of decisions, evidentiary and otherwise, and very limited review of the final award. See Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, Inc., 473 U.S. 614, 628, 105 S.Ct. 3346, 87 L.Ed.2d 444 (1985) (stating that by agreeing to arbitrate, parties “trade[ ] the procedures and opportunity for review of the courtroom for the simplicity, informality, and expedition of arbitration”).
Here, despite the best efforts of experienced appellate counsel to argue otherwise, Mao and Western Digital’s decision to demand arbitration necessarily limited the availability of the protections and advantages of the judicial system. See Bowles Fin. Grp., Inc. v. Stifel, Nicolaus & Co., 22 F.3d 1010, 1011 (10th Cir.1994) (“Those who choose to resolve a dispute by arbitration can expect no more than they have agreed. One choosing arbitration should not expect the full panoply of procedural and substantive protection offered by a court of law.”). In addition, we reiterate that the scope of arbitrator authority is a matter of contract, Law Enforcement Labor Servs., 527 N.W.2d at 824, and par-, ties are always free to fashion arbitration agreements in ways that limit the arbitrator’s power to award certain types of relief.

We next review whether an arbitrator’s imposition of sanctions that preclude any evidence or defense on a claim warrants vacatur as a refusal to hear evidence. Minnesota Statutes § 572.19, subd. 1(4), states that a court shall vacate an arbitration award if “[t]he arbitrators ... refused to hear evidence material to the controversy or otherwise so conducted the hearing, contrary to the provisions of section 572.12, as to prejudice. substantially the rights of a party.” Section 572.12 provides, “The parties are entitled to be heard, to present evidence material to the controversy and to cross-examine witnesses appearing at the hearing.” Minn. Stat. § 572.12(b) (2010). The district court concluded that the arbitrator’s decision to preclude Western Digital and Mao’s evidence on Trade Secrets 4-6 constituted a failure to hear material evidence in violation of Minn.Stat. § 572.19, subd. 1(4); the court of appeals did not address this issue. We review de novo whether the sanctions imposed constituted a refusal to hear evidence material to the controversy and substantially prejudiced the rights of Western Digital and Mao, as described in Minn. Stat. § 572.19, subd. 1(4). See Hibbing Educ. Ass’n v. Pub. Emp’t Relations Bd., 369 N.W.2d 527, 529 (Minn.1985) (stating that statutory construction is a question of law subject to de novo review on appeal).
[766]*766• Western Digital and Mao argue that the punitive sanctions issued against them violated the arbitrator’s duty to hear material evidence. Again, the sanctions precluded “any evidence or defense by Western Digital and Dr. Mao” that disputed the validity of Seagate’s asserted Trade Secrets 4-6, the misappropriation of those trade secrets, or that Western Digital had used those trade secrets. The sanctions also entered “judgment against Western Digital and Dr. Mao of liability for misappropriation and use of’ Trade Secrets 4-6. Western Digital and Mao argue that these sanctions constitute a refusal to hear their evidence and violate principles of fundamental fairness. Seagate responds that the arbitrator heard both sides of the controversy before issuing the award, as Western Digital and Mao were allowed to present witnesses and other evidence, and the court received these submissions. Seagate also characterizes the sanctions as evidentiary determinations, with the arbitrator choosing to not assign weight to evidence that he did not find credible, and argues that the interpretation of the statute proposed by Western Digital and Mao would construe any evidentiary decision as a refusal to hear material evidence.
We begin by noting that the arbitrator heard the challenged evidence at the request of Western Digital and Mao and conducted the hearing in accordance with section 572.12, which requires that the parties be heard, be allowed to present evidence material to the controversy, and be allowed to cross-examine the witnesses appearing at the hearing. Western Digital and Mao’s challenge, therefore, centers not around the admission of evidence, but rather around the arbitrator’s failure to use that evidence when constructing the final award. This challenge differs from our previous case law concerning an arbitrator’s refusal to hear evidence, which has generally involved preventing a party from testifying or submitting certain evidence. See, e.g., Redner v. N. Y. Fire Ins. Co., 92 Minn. 306, 309, 99 N.W. 886, 887 (1904) (involving arbitrators who “refused the plaintiff the privilege of appearing before them, and refused to hear any evidence whatever from the plaintiff, or the witnesses produced by him, or any testimony on' his behalf’).
The scope of Minn.Stat. § 572.19, subd. 1(4), is properly limited to situations involving the presentation and admission of evidence at the hearing, not situations involving the use or weighing of evidence in constructing the final award or other form of relief. This conclusion is supported by the language of Minn.Stat. § 572.19, subd. 1(4), including the incorporation of Minn. Stat. § 572.12. Minnesota Statutes § 572.19, subd. 1(4), focuses on how an arbitrator should conduct a hearing. It addresses an arbitrator’s refusal to postpone the hearing, an arbitrator’s refusal to “hear evidence material to the controversy,” and an arbitrator’s violations of Minn. Stat. § 572.12, which again centers on how a hearing should be conducted. Minn.Stat. § 572.19, subd. 4 (emphasis added); see Minn.Stat. § 572.12 (detailing how to conduct a hearing, including that an arbitrator shall appoint a time and place for the hearing, notify the parties about the hearing, adjourn the hearing, and receive evidence at the hearing). Nothing in either Minn.Stat. § 572.19, subd. 1(4), or Minn. Stat. § 572.12, describes how an arbitrator is to fashion a remedy for misconduct or the final award; the entire focus of these statutes is how the hearing itself should be conducted, not the deliberation process that happens after the hearing.
Based on an analysis of the statutory language, we conclude that it is appropriate to read Minn.Stat. § 572.19, subd. 1(4), as a provision concerned with the admissi[767]*767bility of evidence and the manner in which the hearing is conducted, not as a provision limiting the arbitrator’s authority to use, or refuse to use, certain evidence when providing relief or fashioning an award after the hearing has been completed. In this case, Western Digital and Mao do not challenge any of the arbitrator’s actions during the hearing, as Western Digital and Mao were allowed to present their case in full and the arbitrator received the evidence in question. But the arbitrator chose not to factor this evidence into the final award because of sanctions that were awarded and, as discussed above, were permissible as within the arbitrator’s authority. In short, Western Digital and Mao’s challenge, which is primarily about the. arbitrator’s refusal to use certain evidence in fashioning the final award, is outside the scope of Minn.Stat. § 572.19, subd. 1(4).
III.
Having concluded that the arbitrator did not exceed his authority or refuse to hear material evidence as provided in Minn. Stat. § 572.19, subd. 1, we affirm the court of appeals’ decision reinstating and confirming the arbitration award in full. Because the award is confirmed and no rehearing is required, we do not reach the issue of whether the district court erred in ordering a new arbitrator for the rehearing of issues related to Trade Secrets 4-6.
Affirmed.
