[1409]*1409OPINION
By the Court,
Springer, J.:
JACKTORIAN H., No. 28130
This is an appeal from an order of the juvenile division of the district court which certifies the subject minor, Jacktorian H. (“J. H.”), for prosecution as an adult. In this opinion we clarify the certification provisions of former NRS 62.080, as amended in 1995, and remand to the juvenile division with instructions to reconsider the matter in light of our interpretation of NRS 62.080(2) (b).
Prior to the 1995 amendment to NRS 62.080(2), all persons under eighteen years of age were “presumed to come within the jurisdiction of the juvenile court,” and there could be no certification from the juvenile court to the adult court unless it was “made to appear clearly and convincingly that the public safety and welfare require[d] transfer.” In the Matter of Seven Minors, 99 Nev. 427, 437, 664 P.2d 947, 953 (1983). Under the 1995 amendment, it is declared that the public safety and welfare require certification to adult court in juvenile cases involving the use or threatened use of a deadly weapon; and in such cases the juvenile court “shall certify” the child for criminal proceedings unless the court finds that the child was “not a principal actor” or that certain “exceptional circumstances exist.” Under the statutory amendment, underaged persons charged with offenses involving the use of a deadly weapon are presumed not to come within the jurisdiction of the juvenile court.
Although this case presents serious questions as to whether J. H. has been sufficiently “charged” with an offense involving a deadly weapon so as to give rise to the presumption of certification, we base reversal of the juvenile court’s denial of certification on its quite understandable misapplication of the “exceptional circumstances” language in the statute. The pertinent language of NRS 62.080(2) at the time of J. H.’s certification was as follows:
If a child 14 years of age or older is charged with . . . [an] offense involving the use or threatened use of a deadly weapon or an attempt to commit such an offense, ... the [1410]*1410juvenile division . . . shall certify the child for proper criminal proceedings to [the adult court] unless the court specifically finds that the child was not a principal actor in the oifense or that exceptional circumstances exist because the child’s actions were substantially the result of his substance abuse or emotional or behavioral problems[,] and such substance abuse or problems may be appropriately treated through the jurisdiction of the juvenile division.
Under the statute in question, before a child can, in certification proceedings, be said to have been charged with an offense involving a deadly weapon, the State must plead in some manner and establish probable cause that the child committed an offense involving a deadly weapon. To establish its prima facie case and thus bring into operation the presumption of certification, the State must file a petition, motion or other pleading which puts the child on notice that certification is being sought. The State must then show that there is “prosecutive merit” to the charge.1
[1411]*1411“Prosecutive merit” is an expression that comes from the appendix to Kent v. United States, 383 U.S. 341 (1966), and refers to the standard of proof to be applied at the first phase of a certification hearing. It involves some showing by the State that the juvenile committed the charged act. As pointed out in Breed v. Jones, 421 U.S. 519 (1975), the “Court has never attempted to prescribe criteria for, or the nature and quantum of evidence that must support a decision to transfer a juvenile for trial in adult court.” This court has, however, “prescribe[d] criteria” for establishing prosecutive merit in the following terms:
A preliminary determination of prosecutive merit is to be made to assure that there is probable cause to believe that the subject youth committed the offense or offenses charged.
In the Matter of Seven Minors, 99 Nev. 427, 442, 664 P.2d 947, 957 (1983).
Once the State has pleaded its certification charges and has established “prosecutive merit” by showing that there is probable cause to believe that the child has committed an offense involving the use or threatened use of a deadly weapon or an attempt to commit such an offense, a presumption is created under which the juvenile court “shall certify the child for proper criminal proceedings.” At this point the burden of going forward shifts to the respondent child who must then present evidence either that he or she was not a “principal actor in the offense” or that mitigating, “exceptional circumstances,” of the kind set out in the statute, exist. Because it is clear that J. H. was the only actor and therefore the principal actor in this offense, we will deal only with the questions relating to the “exceptional circumstances” portion of the statute.
Before discussing the mitigating “exceptional circumstances” which, according to the statute, must be the cause of the “child’s actions,” we first address whether the presumption created by the statute went into effect at all in this case. Absent “prosecutive merit” to the charges, there can be no presumption. The limited facts that can be gathered from this record reveal that the State’s establishment of prosecutive merit is problematical. J. H. is charged with assault with a deadly weapon and with burglary. [1412]*1412The assault with a deadly weapon charge stems from a charged “unlawful attempt... to commit a violent injury” upon another boy. The burglary charge is that J. H. entered the boy’s home through an unlocked door “with the intent to commit assault or battery.” The original juvenile court petition alleges that J. H. “slash[ed] at the victim with a knife.” The “slashing” charge appears from the record to be limited to J. H.’s angry brandishing of a knife during a quarrel with the mentioned boy concerning the boy’s treatment of J. H.’s sister. Although the formal charge against J. H. is that he “attempt[ed] ... to commit violent injury,” the facts relating to the charged attempt to commit violent injury and to the specific intent necessary for a burglary charge were never aired in these certification proceedings.
In Seven Minors, we ruled that certification could not be carried out without the “necessity for establishing the merit of the prosecution’s case as a condition for proceeding with the transfer [certification] process.” 99 Nev. at 437, 664 P.2d at 953. “Unless probable cause is conceded by the minor, the court should proceed to hear and determine this issue before proceeding further.” Id. Although it does not appear that counsel for J. H. expressly “conceded” the prosecutive merit issue, counsel made no effort to oppose the State’s affidavit on this issue.
To establish probable cause that J. H. did actually “attempt” to “commit violent injury” on the boy by “slashing” at him, the State relied entirely on an affidavit of some kind. As J. H.’s counsel did not include this affidavit in the record on appeal, we have no idea as to the weight or sufficiency of the evidence supporting prosecutive merit. Rather than oppose the State’s evidence and pursue J. H.’s version of the case, namely, that he did not threaten the boy with a knife during their quarrel {see note 2, infra), J. H.’s counsel stated to the juvenile court that counsel was “not going into the facts” of the case. J. H.’s counsel made no attempt to counter the State’s case with regard to prosecutive merit and indicated to the court that “if we had submitted affidavits,” they would have “indicated] that the victim [was] a crack head and that it didn’t happen this way and there was no knife and that I know that that’s not going to be the issue.”2
[1413]*1413From the few facts that appear in the record, J. H.’s version appears to be that he had been offended by the way in which the “victim” had treated his sister, that he did not threaten the boy with a knife, and that he did not have any intent to harm the boy, much less to “commit violent injury.” Under Keys v. State, 104 Nev. 736, 766 P.2d 270 (1988), the State must prove a specific intent in order to establish the crime of attempt. Although prose-cutive merit was not litigated, there was a strong possibility that mental elements of the assault charge as well as the burglary charge would have been very difficult to prove. It is therefore possible that the case might have ended at the prosecutive merit stage of the proceedings.
Because we are reviewing the subject statutory amendment for the first time, the prosecutive merit aspect of these certification proceedings has been discussed; however, this question was not raised by J. H. on appeal. We rest reversal of the order of certification in this case, then, not upon infirmities in the “charge” upon which the presumption is based; rather, we decide on the basis of the juvenile court’s incorrect reading of the following clause in the amended statute:
that exceptional circumstances exist because the child’s actions were substantially the result of his substance abuse or emotional or behavioral problems ....
NRS 62.080(2)(b).
We agree with J. H.’s contention that the juvenile court did not properly define or apply the “exceptional circumstances” provision of the statute. The trial judge, quite understandably, read the statutory language narrowly to mean that in order to rebut the presumption of certification, he had to find that J. H.’s criminal “actions were substantially the result” of J. H.’s substance abuse, that is to say, that the charged behavior was caused by substance abuse and not by J. H.’s volitional acts. The trial judge could not and would not find that J. H.’s actions were the “result” of substance abuse. The juvenile court judge certainly cannot be faulted for this reading of the statute. The statute says that the criminal actions must be the result of substance abuse, and the [1414]*1414judge simply concluded that criminal actions cannot be the result of drug use. Reading the statute in the way that he did, the judge necessarily took the position that there was no set of facts under which he could find that criminal conduct was the result of substance abuse. Given the juvenile court judge’s frame of mind, it would not appear that J. H. had any chance of rebutting the presumption of certification.
The construction of a statute is a question of law. Moody v. Manny’s Auto Repair, 110 Nev. 320, 325, 871 P.2d 935, 938 (1994). “The leading rule of statutory construction is to ascertain the intent of the legislature in enacting the statute.” McKay v. Bd. of Supervisors, 102 Nev. 644, 650-51, 730 P.2d 438, 443 (1986) (citations omitted). Generally, when the words in a statute are clear on their face, they should be given their plain meaning unless such a reading violates the spirit of the act. Hotel Employees v. State, Gaming Control Bd., 103 Nev. 588, 591, 747 P.2d 878, 879 (1987). Thus, we have previously held that “when a statute’s language is clear and unambiguous ‘there is no room for construction.’ ” Rodgers v. Rodgers, 110 Nev. 1370, 1373, 887 P.2d 269, 271 (1994) (quoting State v. Jepsen, 46 Nev. 193, 196, 209 P.2d 501, 502 (1922)).
In other words, the plain meaning of a statute’s words are presumed to reflect the legislature’s intent in enacting the statute. Nevertheless, statutory language should not be read to produce absurd or unreasonable results. Alsenz v. Clark Co. School Dist., 109 Nev. 1062, 1065, 864 P.2d 285, 286 (1993). When the words of a statute clearly contradict the legislature’s intent, the intent of the legislature will predominate:
“The leading rule for the construction of statutes is to ascertain the intention of the legislature in enacting the statute, and the intent, when ascertained[,] will prevail over the literal sense. The meaning of words used in a statute may be sought by examining the context and by considering the reason or spirit of the law or the causes which induced the legislature to enact it. The entire subject matter and the policy of the law may also be involved to aid in its interpretation, and it would always be construed so as to avoid absurd results.”
Moody, 110 Nev. at 325, 871 P.2d at 938 (quoting Welfare Div. v. Washoe Co. Welfare Dep’t, 88 Nev. 635, 637-38, 503 P.2d 457, 458-59 (1972)).
Here it was clearly not the intention of the legislature that certification should automatically result in all deadly weapons [1415]*1415cases; otherwise, no exceptions would exist, and all such cases would be subject to mandatory certification. See Paramount Ins. v. Rayson & Smitley, 86 Nev. 644, 649, 472 P.2d 530, 533 (1970) (noting that “no part of a statute should be rendered nugatory, nor any language turned to mere surplusage, if such consequences can properly be avoided”). The legislature intended that some cases with deadly weapons involvement would not require certification; therefore, we will undertake an interpretation of the statutory language that will give suitable recognition to that legislative intent.
The juvenile court judge showed justifiable consternation in his efforts to apply this statute in the present case. The judge remarked that “this part of the statute is extremely unfortunate [because] there are a tremendous number of words that almost exclude any circumstance that this court could ever envision . . . [for] applying” the statute.
The juvenile court’s quandary is not difficult to understand. On its face, the statute requires the court to find that criminal actions were not the exercise of free will but, rather, the result of factors beyond the control of the actor, namely, substance abuse, emotional problems or behavioral problems. Counsel for J. H. obviously understood the problem when he conceded that “psychologists . . . tell me we can never say . . . that the emotional or behavioral problem or substance abuse problem cause them to commit the crime.” (Emphasis added.)
The juvenile court judge confirmed the jurisprudence of this court when he recognized that the law has not “recognized the use of drugs as a legitimate excuse for criminal behavior. Thus, his concern that the statute required him to do just that would lead to an absurd result. This court has similarly eschewed “the deterministic principle that youthful law violators are not morally or criminally responsible for their behavior but, rather, are victims of the environment” or of mental or emotional conditions that are claimed to have caused them to commit crimes. Seven Minors, 99 Nev. at 431, 664 P.2d at 950. We agree with the trial judge that criminal conduct on the part of mentally competent actors cannot be said to have been caused by or to be the result of substance abuse or other similar problems in the life of juvenile offenders.3 As we have said, criminal conduct is caused by and is the result of a free-will decision to engage in prohibited conduct.
[1416]*1416That criminal actions cannot properly be said to be the result of substance abuse or emotional problems is, of course, not to say that substance abuse or emotional problems are not frequently important factors, perhaps overwhelming factors, in explaining a juvenile’s decision to commit a crime. This does not mean, however, that criminal conduct should be excused or mitigated because it is thought to be the result of substance abuse and not the result of culpable criminal “actions.”
We believe that the statute can be read in a way that does not require the juvenile court judge to recognize drugs as a “legitimate excuse” for delinquency and does not require the juvenile court judge to find, in order to apply the “exceptional circumstances” provisions in the statute, that the criminal actions were the “result of” substance abuse or emotional or behavioral problems.
It is common knowledge that drugs are “involved” in some way in a significant number of crimes; and it is certainly safe to say that drug use is present in (rather than the cause of) a substantial number of criminal activities. It is also the case, particularly in juvenile court, that emotional or behavioral disorders contribute in no small measure to the final, voluntary decision to commit a criminal act.4 We conclude, then, that reading the statute in accordance with the legislature’s intent, J. H.’s criminal actions did not have to be “substantially the result of substance abuse” but, rather, substance abuse had to have substantially influenced or contributed to J. H.’s criminal actions. It will, of course, be the juvenile court judge, in these kinds of cases, who determines and makes findings as to whether substance abuse, emotional problems or behavioral problems have [1417]*1417had a “substantial” influence on or contribution to a child’s criminal actions or are insubstantial and tangential.5
We conclude, then, that the juvenile court judge misinterpreted and misapplied the statute when he took the position that criminal actions are not the result of substance abuse and that, therefore, the statute required him to certify J. H. “for proper criminal proceedings.” This narrow interpretation is contrary to the intention of the legislature, which intended that the presumption be rebuttable under some circumstances. As pointed out in the margin, there is evidence that this young man has a serious drug problem, had a “need to participate in drug treatment” and “would be more appropriately treated through the jurisdiction of the Juvenile Court.” {See note 2, supra). If the juvenile court judge in this case had been asked to find whether substance abuse substantially contributed to or substantially influenced J. H.’s actions and whether his “problems may be appropriately treated through the jurisdiction of the Juvenile Court,” the judge’s decision may very well have been different from the one rendered in this case.
Because it appears that the juvenile judge in this case did not certify J. H. to the adult court because the judge’s quandary over the meaning of NRS 62.080(2), it is necessary to reverse the judgment below and remand to the juvenile division of the district court for further proceedings.6
[1418]*1418
ANTHONY LEE R., No. 27772
This juvenile certification case was decided by the same juvenile court judge that decided the Jacktorian case. This case, however, involves charges that are much more serious in nature than in Jacktorian. Anthony is charged with a flagrant robbery with a deadly weapon aggravated by his abusive and lewd abuse of his female victim. The juvenile court judge properly defined the charges in this case as being “horrendous,” and commented that the juvenile court does not “deal[] with this type of offense very well.”
Again, as in Jacktorian, the juvenile court judge complained that the “exceptional circumstances” provisions in NRS 62.080 were “vague” and commented on the record that he did not know what the statutory terms “substantially” and “result of” meant and said that he did not “think anybody else does.”
It is probably the case that the juvenile court judge would have certified this youth to the adult court even if he had in hand the interpretation of the statute provided in Jacktorian, above.7 As pointed out in Jacktorian, the statute creates a presumption of certification that cannot be overcome unless the respondent minor establishes that drug abuse or the other factors mentioned in the statute “substantially influenced or contributed to” the charged criminal actions.
Because the statute has engendered legitimate confusion that has not been clarified until now, we have no choice other than to remand this juvenile certification matter to the juvenile court so that it can proceed in the manner described in Jacktorian. The [1419]*1419judgment of the juvenile court is reversed and the matter is remanded to the juvenile division of the district court.8
GENO L., No. 27889
Geno L. was originally charged with four counts that arose from what appears to be a gang-related melee: two counts of battery with a deadly weapon, and two counts of battery with substantial bodily harm. Geno L. was certified to the adult court on three of the charges. One of these charges involves battery of a young woman, Darci, with a deadly weapon, a baseball bat. Geno’s involvement in this battery created a presumption of certification under NRS 62.080(2)(b). The other two charges upon which certification is based are of lesser offense and, of themselves, would not support the certification of Geno, a first offender, to the adult court. The issue in the case, then, is whether the juvenile court erred in its application of the deadly weapon presumption in ordering that Geno be certified for adult prosecution based on the battery of Darci, Count II of the juvenile court petition.
Although this case, like the other cases in this opinion, requires an interpretation of NRS 62.080(2)(b), our interpretation in this case relates not to the “exceptional circumstances” portion of the statute (as in the other two appeals) but, rather, to the provision of the statute which excepts from the presumption a “child [who] was not a principal actor in the offense.” In this case (again, with the same juvenile court judge who presided in Jacktorian and in Anthony), there was an extensive hearing given on the issue of whether Geno was or was not a principal actor in the battery with a deadly weapon charge. The facts of this case are as follows:
On the evening of September 1, 1995, Frank and Darci were roller blading with Frank’s brother, Richard, who was riding a mountain bike. The trio had just picked up food and drinks and were on their way to a park to eat when they reached the intersection of Torrey Pines and Carmen in Las Vegas. A car with seven teenage occupants arrived at the intersection at the same [1420]*1420time. Geno was in the car along with Nick, Kristen, Toby, Tommy, Mark, and Sarah. Toby shouted an insulting remark at Frank, Darci, and Richard, who were on the corner, and apparently Frank responded in kind.
Nick, who was driving, stopped the car; Toby got out and approached Frank, who had bent down in an unsuccessful attempt to remove his roller blades. According to Darci’s testimony, Tommy, Nick, and Geno then approached Frank, surrounded him, and began to hit and kick Frank. However, Mark (whom the State chose not to prosecute) testified at the certification hearing that Geno stood by him at the car during the altercation between Frank, Toby, Tommy, and Nick. Darci acknowledged that Mark had not participated in the incident. Sarah, who stayed in the car with Kristen during the entire incident, testified that she saw Mark standing by the car, but did not see Geno. She further testified that there was a metal baseball bat on the floor in the back seat of the car and that neither Geno nor anyone else ever took the bat from the car.
As the fight progressed, Frank and his attackers moved into the street, while Darci remained on the sidewalk with Richard. At some point, one of Frank’s assailants knocked Darci to the ground. Darci claimed that while still on the ground, she heard one of the assailants say “get the bat.” Darci testified that she could not identify who attacked her; however, she stated that she had seen Geno approaching her shortly before she was knocked down, but that Geno was not holding a baseball bat at that time. Shortly thereafter, while still on her hands and knees, Darci alleged that she saw a metal baseball bat swinging at the center of her face. She did not see who wielded the baseball bat, but turned her head to the right, absorbing the blow with her left jaw, which was fractured in two places, necessitating reconstructive surgery the following day. At some time, Toby confessed to police that he had hit Darci in the jaw with his fist. Frank was beaten unconscious and suffered severe lacerations to his head and face.
Darci testified that the police reports of the incident, which reported that Darci had jumped on Toby’s back in an effort to help Frank, and that Toby had subsequently hit her, were inaccurate. She maintained that she could not identify who broke her jaw, and she denied ever physically engaging any of Frank’s assailants. Various witnesses were on the scene, but almost all of them refused to give statements, claiming that they were afraid of retribution from Frank and Darci’s assailants. According to police, several witnesses stated that they had seen a baseball bat used during the fight. A metal baseball bat was recovered from the assailants’ car; however, no usable fingerprints were found on the bat. In Richard’s police statement, he asserted that the man [1421]*1421who attacked Darci was between 5'8" and 5'9". The record indicates that Geno is significantly shorter.
As mentioned above the State petitioned the juvenile court to certify Geno as an adult on the four counts charged. One week before the certification hearing, a probation officer submitted a report recommending denial of certification. The probation officer’s recommendation that certification not be carried out was based on his belief that there had to be “stronger evidence to show Geno’s direct involvement in these [b]atteries” before he would recommend certification.
In this case, unlike Jacktorian, there was in fact a pleading filed, a “Certification Petition,” asking that the court certify Geno to the adult court; however, no mention is made in the petition of the presumption created by NRS 60.080(2)(b) or of the “principal actor” exception to the presumption rule. It is clear from a transcript of the hearing, however, that Geno was on notice of the charge upon which certification was based in this case and that the crucial issue before the court was whether or not Geno was a “principal actor” in the battery.
As recognized by the juvenile court, this is a “difficult” case, and although there is some evidence that Geno was involved to some degree in the fray, there is little if any evidence of his “principal” involvement in the crime of battery with a deadly weapon, battery with a baseball bat. No one saw Geno with a bat in his hand; Geno was smaller than the assailant described by witnesses as the wielder of the bat, and there were no fingerprints or other physical evidence that Geno battered Darci with a baseball bat. Although Darci, the victim of the battery, saw Geno standing nearby before she was struck, she could not testify that it was Geno who battered her with the bat.
As in Jacktorian, we note in this case that a presumption is created whenever an “offense involving” a deadly weapon is charged and the prosecutive merit of the charge is established by the State. The juvenile court held that the battery with a deadly weapon charge had prosecutive merit. We conclude that there was enough evidence for the juvenile court to conclude that Geno was charged with an offense “involving the use ... of a deadly weapon” and that, accordingly, it must be presumed, under NRS 62.080(2)(b), that Geno should be certified unless it appears that he was “not a principal actor in the offense.” It was therefore incumbent upon Geno to rebut the presumption by a showing that he was “not a principal actor in the offense.” Put another way, it was established that Geno was an “actor” in the offense, and the only issue before the juvenile court was whether he was a principal actor.
Although Geno was situated near Darci when she was battered, [1422]*1422it is anything but clear that he was the actual batterer. If anyone had seen him with a baseball bat in hand or had actually seen him strike the victim, obviously there would be no problem in this case, and it would be clear that Geno was a principal actor; Geno’s “principal” involvement is tenuous at best.
The juvenile court, understandably, had “difficulty with this one” — “trying to dissect a fight” — and described the decision to certify as “an awfully close call.” The judge further commented that “the term principal actor is . . . one that has yet to be defined by the legislature” and went on to make the critical comment that “all those that participated in the fight in some fashion were principal actors.” The trial judge’s statement that he believed all participants in the fray to be principal actors renders the question of whether Geno was the actual assailant immaterial. Under the juvenile court’s definition of principal actor, Geno was a principal actor just by being there and “participating” in some way in the total fray.
The term “principal actor” loses all meaning and significance if it is said that all participants in criminal activity are “principal actors”; consequently, we must hold that the juvenile court erred in giving the expression that broad an interpretation to the term. If the term principal actor is to be given any cognizance, some meaning must be given to the word, “principal.”
Although, as pointed out by the juvenile court judge, the legislature provided no definition of the word, “principal,” this is a word of common usage, meaning “chief” or “main.” Webster’s New International Dictionary 1966 (2d ed. 1948). A “principal” actor can be distinguished from an actor who plays only a small, peripheral role in the commission of a crime.
The word “principal” in the term “principal actor” must be distinguished from our statutory definition of “principal,” which is “[ejvery person concerned in the commission of a felony . . . whether he directly commits the act constituting the offense, or aids or abets in its commission” and, as well, any person who “whether present or absent . . . counsels, encourages, hires, commands, induces or otherwise procures another to commit a felony.” NRS 195.020. The statutory definition of a “principal” is in harmony with the trial judge’s definition of “all those who participate in some fashion”; but this, we believe, is a broader definition than that intended by the legislature to be applied in cases in which those who have an insubstantial role in a crime may be excepted from the presumption of certification by reason of their not being “principal actor[s]” in the offense.
Geno would be a “principal actor” if he had actually battered [1423]*1423the victim, or counseled or commanded some other assailant on the scene to batter the victim or held the victim while another assaulted her. There are many ways in which Geno could have been a “principal actor” in the battery with a deadly weapon committed here; however, if, as he claims, he was just standing there when some other youth battered Darci, without notice to him, he could be said to have committed an “offense involving the use of a deadly weapon,” but he would not be, under the meaning of the term in our statute, a “principal actor.”9
Given the trial judge’s overbroad and incorrect definition of principal actor, including all participants in the crime as principal actors, it is necessary that we remand this case for a new determination of whether Geno can establish that he was not a principal actor in the offense of battery with a deadly weapon.
Geno’s certification order is reversed, and the matter is remanded to the juvenile division of the district court.
Rose and Young, JJ., concur.
