OPINION
Defendant Frank E. Pharris appeals the jury verdict finding him guilty of injury to a jail in violation of Utah Code Annotated section 76-8-418 (1990). On appeal, defendant contends that (1) the State violated his constitutional rights by improperly using peremptory challenges to prevent Native Americans from being impaneled on the jury deciding his case, (2) the statute under which he was charged is unconstitutionally vague, and (3) the trial court erred in refusing to instruct the jury on the lesser included offense of criminal mischief, Utah Code Annotated section 76-6-106 (1990). 1 We reverse in part and affirm in part.
BACKGROUND
Defendant was an inmate in the San Juan County Jail on November 22, 1990, when he and a fellow prisoner created a destructive disturbance in the jail. During that afternoon, because defendant and co-defendant 2 had become intoxicated, jail officials placed each of them in isolation. Just before 6:00 p.m., a guard heard defendant either jumping or banging on his bunk. When he looked into defendant’s cell, the guard saw him repeatedly flushing a clogged toilet, causing gallons of water to pour out on the floor. Defendant was yelling, ranting, and making obscene gestures.
The guard called for assistance and turned off the water to defendant’s cell. He then noticed that water was pouring down from co-defendant’s isolation cell directly above the cell occupied by defendant. The water from the two toilets combined to flood both the cell and the day room outside the cell with between one-half and three-fourths inches of water. When the guards returned from shutting off the water to co-defendant’s cell, defendant was banging his fist against the light fixture in his cell, displacing, but not breaking its bracket. Upon removing defendant from the cell, the guards discovered that the welds holding up the bunk were broken. After the fifteen minute incident, defendant’s cell was unusable, a welder had to repair the bunk, a painter had to repaint the wall, and maintenance had to remove about eighty-five gallons of water from the carpet of the day room.
The water seeped into the basement where it soaked the jail’s backup generator, causing it to smoke. Testimony about damage to the generator was conflicting. At the preliminary hearing, the officer in charge of the jail during the incident testified that the generator was in working order after the incident. At trial, however, the maintenance man who inspected and worked on the generator testified that the generator had to be turned off to dry and that the next day he discovered that the generator’s automatic clock had broken. He testified that turning off the generator for repair left the jail without backup power for twenty-four hours.
As a result of this incident, both defendant and co-defendant were charged and later convicted of a felony, injuring a jail. On appeal, defendant does not dispute the facts so much as he challenges the procedure allowing these facts to become a basis for his conviction.
*458 Both during the trial and on appeal, defendant challenged the prosecutor’s use of peremptory strikes to prevent Native Americans from serving on the jury which would hear his case. After the trial court removed several potential jurors from the venire for cause, five of the remaining potential jurors were Native Americans. The prosecutor questioned two of those Native Americans during voir dire about possible familial relationships with individuals recently prosecuted by the County Attorney’s office. The first, Ms. Bedonie, related that she was a close family friend of the person about whom she was asked, but also stated that she could put this relationship aside to decide the case before her. The second, Ms. Gray, stated that she did not know the individual named by the prosecutor although he did have her same married name and came from the same general vicinity of the state as she. The prosecutor then used the first three of his four peremptory challenges to strike Native Americans, including the two women questioned during voir dire. The jury that was later impaneled included the two remaining Native Americans among its eight members.
Near the end of the jury selection process and before the trial court impaneled the jury, both defendant’s and co-defendant’s attorneys requested that the prosecutor provide race neutral explanations for challenging the Native Americans. The trial court overruled defendants’ objection to the petit jury, stating that the prosecutor “need not respond in any fashion to the inference or challenges.” The prosecutor, however, immediately stated that he was willing to go on the record with regard to two of the challenges he had made. He explained that he based the challenges of both Ms. Gray and Ms. Bedonie on his suspicion, aroused during earlier questioning, that they might be related to individuals that his department had prosecuted. When defendant’s counsel asked for an explanation for the prosecutor’s challenge of the third Native American, the court foreclosed further discussion on the matter.
Defendant renewed his objections in a motion to arrest the judgment following defendant’s conviction, at which time he submitted an affidavit providing statistics contrasting the 43.57% Native American population of the county with the 25% Native Americans impaneled in the jury. When the trial court denied defendant’s motion to arrest the judgment, defendant appealed.
DISCRIMINATION IN JURY SELECTION
On constitutional grounds, defendant challenges the selection process through which the jury was impaneled. Defendant claims that the trial court erred in refusing to require the prosecutor to defend his peremptory challenges of Native Americans. 3 The State counters this challenge by contending that the trial court’s insistence that the prosecution need not respond to defendant’s challenge was an implicit ruling that defendant had not made out the necessary prima facie case of discrimination. The State asserts that the proper issue before this court is whether defendant had established a prima facie case “such that the State should be compelled to respond to rebut the presumption.” While we agree with the State’s statement of this issue, we disagree with both its analysis of the trial court’s re *459 sponse and with the trial court’s conclusion.
Standard of Review
The trial court’s conclusion as to whether or not a prima facie case was established is a legal determination which we review for correctness, according it no particular deference.
See State v. Crowder,
Inapplicability of Harmless Error Analysis
Both parties in this case agree that if the State’s peremptory challenges were purposefully discriminatory, defendant’s conviction must be reversed without regard to the harmlessness of the constitutional error. This stipulation is consistent with the directive in
Batson
that if a court finds unrebutted, purposeful discrimination, “precedents require that [a] petitioner’s conviction be reversed.”
Batson,
Role of the Trial Court
This court recognizes a long standing judicial commitment to eradicating discrimination in the jury selection process.
See Strauder v. Kentucky,
Because the Supreme Court has interpreted the equal protection clause of the Fourteenth Amendment as guaranteeing defendants a trial before a jury selected through a nondiscriminatory process, the Court has required careful monitoring of the various stages of the process by which the trial court impanels a petit jury.
See Batson,
The
Batson
Court recognized that “peremptory challenges constitute a jury selection practice that permits ‘those to discriminate who are of a mind to discriminate.’ ”
Batson,
The
Batson
Court noted that the enforcement of this equal protection guarantee poses difficult evidentiary problems for the party alleging discrimination.
Bat-son,
In setting out this analytical framework, the
Batson
Court declined to formulate specific procedures which a trial court must follow in responding to a defendant’s timely objection to a prosecutor’s peremptory challenges.
Batson,
Subsequent Court decisions support the
Batson
Court’s delegation of responsibility to the trial court to develop techniques by which to evaluate discrimination allegations: “It remains for the trial courts to develop rules, without unnecessary disruption of the jury selection process, to permit legitimate and well-founded objections to the use of peremptory challenges as a mask for race prejudice.”
Powers v. Ohio,
499 U.S. -,
Post-Batson
Supreme Court decisions have also emphasized the importance of the trial court’s duty of careful evaluation. The
Powers
Court expressed the theory underlying this responsibility: “[I]f the trial court has no duty to make a prompt inquiry ... [t]he composition of the trier of fact itself is called in question, and the irregularity may pervade all the proceedings that follow.”
Powers,
499 U.S. at -,
Viewing the Batson analytical framework in light of these directives indicates that the role of the trial courts is pivotal in the overall effort to eliminate racial discrimination in the jury selection process. By taking an active role in assessing objections to peremptory challenges, the trial court can arrest such discrimination at the earliest possible juncture. After making appropriate determinations, the trial court must record sufficient findings of fact to allow a reviewing court to follow its analysis regarding the challenges.
In the case before this court, the trial court’s cursory treatment of defendant’s challenge of the prosecution’s peremptory strikes against Native Americans did not live up to the Supreme Court’s standard. The trial court did not conduct a sensitive inquiry; it did not follow the outlined three step procedure for analysis of a discrimination allegation; its findings of fact were incomplete; and it misstated the law in its justifications for dismissing defendant’s objections. For these reasons, this court reverses the trial court’s decision finding no *462 impropriety in the prosecution’s peremptory challenges.
The Prima Facie Case
Because of the importance of preventing racial discrimination in jury selection, state and federal appellate courts have developed criteria for trial courts to use in assessing the prima facie element of the
Batson
analytical process.
See State v. Span,
Defendant argued that his mere assertion of discrimination combined with the under-representation of Native Americans on the trial panel shifted the burden to the State and required the trial court to demand and evaluate the State’s explanation.
6
Preliminarily, this court recognizes that although the
Batson
holding authorized defendants to inquire into the State’s good faith in the use of its peremptory challenges, a mere assertion of impropriety does not trigger the court’s responsibility to conduct a
Batson
inquiry.
State v. Harrison,
To compel a
Batson
inquiry, the challenging party must instead make out a prima facie case by presenting facts adequate to raise an inference of improper discrimination.
Batson,
In determining whether discrimination against a distinctive group has occurred, trial courts should consider disproportionate impact as circumstantial evidence of invidious intent.
Batson,
In the instant case, the prosecutor exercised peremptory challenges against Native Americans in the first three of his four challenges. For purposes of
Batson
analysis, this court takes judicial notice of the fact that Native Americans constitute a distinctive group in this region.
See Redd v. Negley,
In the case before this court, defendant generally asserted that these peremptory challenges were racially discriminatory and created a panel under-representing Native Americans. He specifically noted that the prosecutor used three of his four peremptory strikes (75%) to exclude Native Americans from the panel and offered statistics demonstrating that the racial composition of the petit jury changed significantly from that of the initial jury pool. Defendant also pointed out that the prosecutor conducted no voir dire questioning at all of one of the excluded Native Americans. We conclude that these indicia of racial discrimination, when viewed cumulatively, satisfy the criteria of a prima facie case of racial discrimination in the selection of the jury in defendant’s case.
The Race Neutral Explanation
Because defendant made out a pri-ma facie case, the trial court should have recognized that the burden of proof shifted to the prosecutor to provide race-neutral justifications for his actions.
Batson,
Utah has adopted additional criteria by which to judge the adequacy of a party’s explanation of an allegedly racially motivated peremptory challenge. The trial court must discount justifications if the prospective juror was (1) not shown to share an alleged bias, (2) not examined or subjected only to perfunctory examination by the prosecutor when neither the trial court nor the defense had questioned him or her, (3) singled out for questioning to evoke a specific response, (4) challenged for a reason unrelated to the trial, or (5) challenged for reasons equally applicable to other jurors not similarly challenged.
*464
Span,
In this case, although the trial court summarily dismissed the allegations of discrimination, the prosecution voluntarily provided explanations for two of its three peremptory challenges exercised against Native Americans. 9 The prosecutor explained that he had removed those Native Americans because he suspected they might be related to individuals that his office had prosecuted. The trial court should have evaluated these statements according to the Batson criteria and the Utah Supreme Court’s factors, but did not.
The record also shows that the prosecution did not question the third Native American dismissed by a peremptory strike at all.
Post-Batson
cases have indicated that the improper dismissal of even one venireman is intolerable.
See Span,
Determination by the Trial Court
It is the trial court which must determine if a defendant has established that purposeful discrimination tainted the jury selection process.
Batson,
To promote comprehensive analysis, trial courts must allow defendants an opportunity to attack the justifications offered by the prosecution for striking prospective jurors. Id. Defendant asserted that the prosecutor’s explanation for challenging the first prospective juror did not adequately indicate bias relevant to the instant case. He implied that the explanation for the second juror was pretextual by stating that it was based simply on the juror’s having the same last name and coming from the same broad general area as a formerly prosecuted individual whom she denied knowing. Defendant also noted that the prosecutor questioned only two of the three stricken Native Americans during the voir dire and explained only those two challenges. To determine whether defendant proved improper discrimination, the trial court should also have considered these responses to the prosecution’s rebuttal.
Because of the necessity of evaluating the discrimination issue according to specific analytical guidelines, the trial court must create a complete record. The trial court in this case, however, merely recorded incomplete, conclusory statements in its findings of fact on defendant's motion to arrest the judgment. Any lack of record or trial court failure to rule on the issue of race-neutrality creates difficulty in assessing the adequacy of the prosecutor’s explanations on appeal.
See Span,
The inadequacy of the findings is exemplified by the trial court’s failure to record its evaluation of credibility. Utah has recognized that the trial court’s determination of the discrimination issue may turn on its assessment of the credibility of the party
*465
defending the peremptory challenge.
Harrison,
The findings in this case not only inadequately addressed essential factual issues, but also misstated applicable law. The trial court’s seventh finding of fact inaccurately distinguished
Batson
stating that it was “not controlling on the facts in this case in that the defendant herein was not a Native American.” This distinction is immaterial in light of post-Raiscm cases which conclusively hold that a defendant need not share the same racial background as the jury members stricken by peremptory challenges.
Powers,
— U.S. at-,
Having determined that the trial court’s stated factual and legal bases for overruling defendant’s objections to the jury selection were either insufficient or erroneous, we remand this case to the trial court for an evidentiary hearing on the race-neutrality of the prosecution’s challenges of all three prospective jurors. The
Batson
directive to remand a case in which the trial court flatly rejects a defendant’s discrimination allegation,
Batson,
INJURY TO A JAIL
Defendant also claims that the trial court erred in failing to dismiss the information against him because the “injury to a jail” statute providing the basis for the charge against him is unconstitutional. That statute, codified as Utah Code Annotated Section 76-8-418 (1990), reads:
Every person who wilfully and intentionally breaks down, pulls down, or otherwise destroys or injures any public jail or other place of confinement is guilty of a felony of the third degree.
Defendant asserts that the statute (1) is unconstitutionally vague in violation of the due process guarantees of the Fifth and Fourteenth Amendments to the United States Constitution, and the similar provisions of Article I, Sections 7. and 12 in the Utah Constitution, and (2) unfairly classifies him by segregating prisoners from the general public in violation of defendant’s right to equal protection of the law as guaranteed by the Fourteenth Amendment to the United States Constitution and Article I, Section 2 of the Utah Constitution. We review the trial court’s decision on the constitutionality of the statute for correctness, according no deference to its legal conclusions.
State v. James,
Generally, we presume the constitutionality of a statute, and defendant, as challenger, has the burden to demonstrate its unconstitutionality.
Greenwood v. City of North Salt Lake,
Vagueness
Defendant argues that this court should invalidate the “injury to a jail” stat
*466
ute under the due process void-for-vagueness doctrine. That doctrine requires a statute to define an “ ‘offense with sufficient definiteness that ordinary people can understand what conduct is prohibited and in a manner that does not encourage arbitrary and discriminatory enforcement.’ ”
Greenwood v. City of North Salt Lake,
Defendant relies upon this due process doctrine for his argument that the statute is invalid both on its face and as applied to the facts of his case. However, because we find that the statute is valid as applied to the facts of defendant’s case, we do not address defendant’s challenge of the facial validity of the statute. Facial invalidity can only be found if a statute is “ ‘incapable of any valid application.’ ”
Greenwood,
Defendant’s as-applied due process challenge fails because he does not prove either that the statute did not provide him adequate notice or that the statute contained no meaningful standards to guide those enforcing the law. Defendant’s broad argument that the statute lacks sufficient specificity in defining the acts and resultant damage which can invoke the sanctions of the law can be reduced to a specific claim that the statute did not provide him fair warning that breaking the cell bunk weld and damaging the power generator by flooding the jail cell could result in felony sanctions. However, we find that these acts and the resulting damages fall within the scope of the statute because they caused injury to portions of the jail facility that are essential to its functioning.
This conclusion comports with the reasoning of
State v. Jaimez,
We also rule against defendant’s claim that the statute should fail for allowing enforcement officials unfettered discretion in imposing sanctions. Defendant’s disagreement with the broad interpretation of the statute’s language does not translate into a lack of meaningful standards to guide the application of the statute. The statute sets the standard that any injury to a physical facility used for jail functions can be punished under the statute. Id. at 826.
This directive focuses jail officials on protecting the jail facility. Although defendant argued that the jail staff appeared to be reacting to the prisoners’ vulgar speech and refusal to obey jail rules, these behavioral problems are immaterial to the imposition of charges under the statute. Thus, based upon Jaimez, we conclude that the State properly charged defendant for the damage he inflicted to the bunk bed in the solitary confinement cell and the generator in the basement area.
Equal Protection
This court also disagrees with defendant’s contention that the “injury to a jail” statute violates his right to equal pro
*467
tection by impermissibly punishing jail inmates and prisoners to a greater degree than others. Although defendant based this claim on both the equal protection clause of the Fourteenth Amendment of the United States Constitution and Article I, section 24 of the Utah Constitution, his arguments do not distinguish between these two bases for his claims. Utah courts, however, have recognized that while both provisions “ ‘embody the same principle: persons similarly situated should be treated similarly,’ ” they have different contexts and jurisprudential considerations.
Greenwood v. City of North Salt Lake,
We conclude that the statute challenged in this case satisfies both tests. It applies equally to the entire class of persons who cause injury to a jail in that it authorizes the state to sanction either a member of the general public or an inmate of a prison in the same manner for causing the same type of damage. Because punishing this class of persons has a reasonable tendency to further the statute’s objective of fully protecting the facilities essential to the functioning of a jail, the statute is constitutional.
Instructions on Lesser Included Offenses
Defendant asserts that the trial court improperly instructed the jury by refusing defendant’s requested instructions on the lesser included offense of criminal mischief, under Utah Code Annotated section 76-6-106 (1990).
11
Because a trial court’s decision to refuse a jury instruction presents a question of law, we review that decision for correctness without affording it any particular deference.
State v. Jaimez,
Utah applies a “two-tier ‘evidence-based standard’ ” to determine whether a trial court should give a requested instructions.
Singh,
Under that standard, two conditions must be satisfied before a trial court is required to give the requested instruction: (1) the statutory elements of the offense charged must overlap with those of the included offenses; and (2) the evidence adduced at trial must provide a rational basis for a verdict acquitting defendant of the offense charged and convicting him or her of the included offense.
Id.
Utah has previously applied this standard to contested instructions involving the same two statutes at issue in this case.
See Jaimez,
Defendant argues that the analysis in Jaimez is not controlling in his case because (1) Jaimez did not consider whether the injury to a jail statute was void for vagueness and (2) the specific area injured by defendant’s actions, the basement area housing the courthouse generator, is not a part of the jail. Defendant fails to persuade us with either of these arguments. We decided earlier that the statute is not void for vagueness and now hold that the section of the basement housing the gener *468 ator is part of the jail for purposes of this statute. 12
The Jaimez court’s interpretation of the scope of the noun “jail” is critical to our decision. That court had to determine whether the “jail” had been injured when Jaimez’s act of flooding his cell damaged the ceiling, insulation and light fixtures in the squad room below the cell. Id. at 824. The court noted that, in addition to its other functions, the squad room was used for housing and processing inmates. Id. at 827. Because the room was “used for jail purposes”, the court deemed it part of the jail for purposes of the “injury to a jail” statute. Id.
By defining “jail” in terms of an area which is used to some extent, for jail purposes, the Jaimez opinion provides the authority for us to conclude that the section of the basement used to house the generator is part of the jail. By analogy to the area used for processing inmates, the space housing the machinery providing back up electricity for the jail’s electronic security system, is “used” for an essential jail function. Damaging either the site for prisoner processing or the site providing power to insure jail security could significantly compromise the safe functioning of a jail.
Furthermore, we agree with the Jaimez decision that the difference between the focuses of the two statutes precludes the jury from acquitting defendant of injury to a jail and still convicting him of criminal mischief. Because of the imperative that a jail function properly, the injury to a jail statute focuses on protecting all essential parts of the jail facility. By contrast, the criminal mischief statute focuses on penalizing a person damaging the property of others according to the value of the damage inflicted. See Utah Code Ann. § 76-6-106(2)(c). This valuation concept is immaterial in the context of protecting the functioning of a jail. While costly damage could have minimal impact on the safe functioning of the facility, minimal damage to critical parts of the physical facilities could have disastrous consequences. For this reason, we conclude that protecting each essential part of the facility without regard to the cost of repairing it is rationally related to the goal of inmate and public safety. We, therefore, determine that the trial court did not err in refusing defendant’s requested lesser included instruction.
CONCLUSION
Defendant met the requirements of a prima facie case of racial discrimination in the State’s use of peremptory challenges during jury selection. The trial court erred in its failure to properly evaluate defendant’s allegation of discrimination. We, therefore, remand this case for an eviden-tiary hearing during which the trial court must require the State to rebut each inference of discriminatory peremptory challenge.
If, on remand, the trial court determines that the jury selection process was infected with deliberate discrimination, it must retry defendant’s case. If retrial is necessary, the parties may proceed knowing that the “injury to a jail” statute is constitutional and the lesser included instruction on criminal mischief is not warranted.
BILLINGS and ORME, JJ., concur.
Notes
. Defendant raises additional issues on appeal which we do not address.
See Low v. Bonacci,
. Defendant and the fellow prisoner were tried together as codefendants.
. Defendant originally phrased his claim of error in terms of the court’s failure to require the prosecutor to provide race neutral explanations for his use of preemptive challenges because the challenges resulted in a trial panel that did not reflect a fair cross section of San Juan County.
This claim of error demonstrates confusion between an equal protection challenge based upon
Batson v. Kentucky,
. The Court has, therefore, expanded the limitations on peremptory challenges first imposed on the prosecution in criminal cases,
Batson,
. The
Batson
Court expressly revised the test for analyzing allegations of discrimination developed in
Swain v. Alabama,
. Defendant generally argued to the trial court that the prosecutor’s peremptory challenges were racially discriminatory and resulted in a panel which under-represented Native Americans. In his Memorandum accompanying the Motion to Arrest Judgment, defendant specifically asserted that the prosecutor’s use of 75% of his peremptory challenges to remove Native Americans was sufficient to establish a prima facie case of improper discrimination.
. On remand from the Supreme Court, the Second Circuit held that statistical disparities as to the number of challenges directed toward minority jurors provided a standard for finding a prima facie case of purposeful discrimination.
United States v. Alvarado,
. Utah appellate courts have already reviewed a case from this same county involving an allegation of discrimination against Native Americans in the jury selection process.
Redd,
. Although we found that the record in this case satisfies the elements of a prima facie case, this court has previously held that if a prosecutor fails to contest the adequacy of the prima facie case and instead attempts to rebut the accusation of discrimination, the adequacy of the pri-ma facie case becomes a moot issue and the court must reach the ultimate issue of whether improper discrimination actually occurred.
Harrison,
. The decision construed the "injury to a jail” statute "according to the fair import of its terms” as required by Utah Code Annotated section 76-1-106 (1990), and interpreted it according to the rule of construction focusing on “plain meaning."
