In the instant appeal, appellant presents three issues. First, whether an unsolicited and inadvertent reference by the complaining witness to taking a lie detector test is ground for reversible error where the trial court denied appellant’s motion for a mistrial and gave a curative instruction. Secondly, whether appellant has a legitimate right to make a tactical decision regarding curative instructions being given in his favor, and thus, whether the trial court erred in so instructing the jury without consulting counsel. Thirdly, appellant questions whether the trial court erred in denying appellant’s motion for a new trial based on newly discovered evidence, where two and a half months after the end of trial the complaining witness recanted her testimony. Although the second issue presents an intriguing question, and we note that at least one court has recognized such a right,
People v. Yatooma,
I.
Appellant, Robert Guesfeird, was found guilty, by a jury in the Circuit Court for Caroline County, of four counts of *656 committing child abuse and fourth degree sexual offenses against Tina Seiler, a young teenage girl who lived in appellant’s home under his care and custody. Following his conviction, appellant appealed to the Court of Special Appeals, which affirmed his conviction in an unreported, per curiam opinion. No. 1616, September Term, 1982 (filed Sept. 9, 1983). Certiorari was granted to consider questions of public importance.
Tina Seiler, the complaining witness, was the principal witness in the state’s case and was the only witness to give evidence supporting the allegations. Tina moved into appellant’s household along with her older brother when their natural mother moved in with appellant. At some point, Tina’s mother left the household and appellant’s new girlfriend moved into the house, apparently before the alleged events occurred. Tina and her brother remained with appellant, and appellant later was awarded custody. Tina testified to a continuing practice of appellant forcing sexual intercourse on her, and she described two specific occasions at trial. Although it is confusing from the record, determining all the persons who resided in the household at the time of the alleged events is not pertinent or necessary here.
After approximately a year and a half of recurring incidents of sexual intercourse, Tina ran away. When Tina reached the point of this event in her testimony, the colloquy that is pertinent to the issue in this appeal occurred. When Tina was asked when it was that she eventually went to the authorities at school to discuss the problem, the following dialogue ensued:
“Q. Okay, and then did you eventually go to the school authorities and talk to a Mr. Arnold and some other people?
A. Yes.
Q. Did you tell them what was happening?
A. Um-hum, and that is when I took the lie detector and Bobby a ...
*657 MR. KEHOE [Defense Counsel]: Objection, Your Hon- or. Approach the bench.”
At the bench conference which followed, defense counsel moved for a mistrial on the ground that the jury would infer that the witness had passed the lie detector test. The trial judge inquired about the results of the test, and both counsel informed him that Tina had passed. The trial judge then denied defense counsel’s motion and noted counsel’s objection. Immediately after the bench conference, without consulting counsel, the trial judge gave a cautionary instruction to the jury to disregard any evidence of a lie detector test. Defense counsel promptly noted an objection to the instruction because of the emphasis it had created.
Tina was the only witness for the state to testify to the crimes alleged. Undoubtedly, if she was believed, her testimony was sufficient to support a conviction. As the trial developed, however, it became clear that the crucial question was whether Tina was to be believed.
Tina’s testimony was contradicted by all the other witnesses who testified. Appellant testified and expressly contradicted Tina, denying any sexual misconduct. Appellant further testified that he was suffering from an automobile accident and was on crutches at the time of Tina’s allegations and he therefore had difficulty moving about. Further, Tina’s brother testified that he did not believe Tina’s allegations. He testified that Tina had made approximately ten other similar accusations against several other men. The other accusations included Jim Alton, another man Tina’s mother had lived with for several years. Tina’s mother also testified to the accusations against Alton and added that Tina had retracted her accusation when Alton and her mother confronted her. Tina’s mother testified that Tina explained that her accusation of Alton stemmed from her confusion from having fantasy dreams. Alton testified and corroborated the testimony of Tina’s mother and brother. Tina’s brother suggested that the recent accusations were motivated by Tina’s desire to obtain a *658 change in custody because she was unhappy about performing her assigned household chores.
If the jury believed the testimony of appellant and his witnesses they would have had to acquit the appellant. The crucial issue in the case was the credibility of the witnesses. Indeed, both counsel recognized this and argued the point to the jury. Because the testimony was in direct contradiction, the case turned on whom the jury chose to believe. Obviously, the jury chose to believe Tina and found appellant guilty. Because credibility was the determinative issue in the trial, we must consider whether the trial judge committed reversible error when he denied appellant’s motion for a mistrial after Tina’s inadvertent and unsolicited reference to taking a lie detector test.
II.
The standard for our review of the trial judge’s decision is clear. The granting of a motion for mistrial is within the discretion of the trial judge.
Lusby v. State,
No dispute exists to the well established rule that evidence of polygraph tests is not admissible.
Lusby,
In determining whether evidence of a lie detector test was so prejudicial that it denied the defendant a fair trial, courts have looked at many factors. The factors that have been considered include: whether the reference to a lie detector was repeated or whether it was a single, isolated statement; whether the reference was solicited by counsel, or was an inadvertent and unresponsive statement; whether the witness making the reference is the principal witness upon whom the entire prosecution depends; whether credibility is a crucial issue; whether a great deal of other evidence exists; and, whether an inference as to the result of the test can be drawn.
See, e.g., People v. Yatooma,
In
State v. Edwards,
“When the prosecutor’s questioning inadvertently elicits a witness’s reference to a polygraph test, there is cause for mistrial if, but only if, the reference to the test raises an inference about the result that substantially prejudices the defendant’s case. Kaminski v. State, [63 So.2d 339 (Fla.1952)]; State v. Davis, [351 So.2d 771 (La.1977)]; Commonwealth v. Camm,443 Pa. 253 ,277 A.2d 325 (1971), cert. denied,405 U.S. 1046 ,92 S.Ct. 1320 ,31 L.Ed.2d 589 (1972). In deciding whether to grant or deny a defendant’s motion for mistrial in such a situation, the trial court must weigh various factors bearing on the substantiality of any resulting prejudice to the defendant. Among other factors, it must determine (1) whether the inference as to the result of the test may be crucial in assessing the witness’s credibility, and (2) whether ‘the witness’s credibility play[s] a vital role in the case.’ People v. Whitfield,58 Mich.App. 585 , 589-90,228 N.W.2d 475 , 477-78 (1975).”
Id. The court added that “[t]he fact that the reference is isolated or inadvertent does not alone insure that the reference is not prejudicial.” Id. The court reversed because the credibility of the complaining witness was a crucial issue. She was the principal prosecution witness, whose uncorroborated testimony provided the only basis on which the jury could find the defendant guilty. Id. “The reference was sufficient to inform the jury that she had taken the test, and the natural and reasonable implication of the reference was that she had passed it.” Id. at 987.
In
People v. Yatooma,
In several additional cases where the credibility of the witnesses was a vital issue, courts have found reversible error for the denial of a motion for mistrial where the defendant was prejudiced by a reference to a lie detector test.
See, e.g., Roleson v. State,
Further, the fact that the reference was not solicited by the prosecutor is not determinative. Although the situation of a solicited reference certainly is more egregious, it is only one factor and is not the determinative test; the test is the resulting prejudice to the defendant. Simply putting before the jury the fact that a lie detector test was taken can be the equivalent of revealing the results.
E.g., Kaminski v. State,
In several cases, courts have reversed convictions involving solicited references to lie detector tests. However, the analysis of those courts focuses on the prejudice to the defendant, not on how the statement arose, improper though it may have been. In
Kaminski v. State,
In
State v. Kilpatrick,
“To have put before the jury the additional fact that [the stepdaughter] had been given a polygraph test and ‘failed it, and it didn’t go any farther than this’ (i.e., there was no prosecution by the State), followed shortly thereafter by the inquiry of [the daughter] as to whether she had taken a polygraph test to which she replied, ‘Yes,’ followed by the affirmative act of prosecution, was in effect to reveal to the jury the results of the test given [the daughter].”
Id. The court held that the reference to the test was prejudicial error because “it may well have been the deciding factor in the minds of some, if not all, of the jurors.” Id. Further, although the trial judge did not admonish the jury to disregard the reference to the polygraph tests, the court noted that to have done so might only have emphasized the fact. Id.
Even in cases that have held that a reference to a lie detector test was not reversible error, the courts have not diverged from the focus on prejudice to the defendant. In these cases, the courts simply have found that in the particular facts and circumstances of the particular case, the defendant was not substantially prejudiced by the reference, and hence, the error did not deny him a fair trial. For instance, in
Sullivan v. State,
Similarly, in
State v. Refuge,
Although the appellee points to authority which held that there was not reversible error, those cases simply show particular facts where the prejudice to the defendant was not substantial. Indeed, those courts follow the same analysis that we have reviewed. Comparing appellee’s authority with other cases from the same jurisdictions illustrates that the analysis is no different, and that the particular facts of the cases cited by appellee are distinguishable.
Compare People v. Dumas,
The Maryland cases of
Lusby v. State,
In
Poole,
the reference to a lie detector test was made by the prosecutor in his closing argument. He commented that an alibi witness had not volunteered to take a lie detector test.
Neither
Poole
nor
Lusby
suggests that a witness’s reference to a lie detector test is automatically harmless, or automatically curable by admonishing the jury. Indeed, it is arguable that rather than being curative, such an instruction might only serve to emphasize the prejudice.
See People v. Yatooma,
In the instant case the sole prosecution witness on which the alleged crimes were based was Tina. Her uncorroborated testimony conflicted directly with the testimony of the defendant and all the other witnesses. In this case, credibility was the crucial issue for the jury. Tina, who stated that she had taken a lie detector test, was the principal witness, and the sole prosecution witness whose testimony supported the charges. The unavoidable inference for the jury to make is that if she took the test, she passed and was telling the truth at trial; otherwise, the prosecution would not have gone forward with her as the only witness. We believe some, if not all, of the jurors might well have turned to this inadmissible evidence as the *667 deciding factor in determining whom to believe. Therefore, we hold that it is clear that the defendant was prejudiced by the witness’s inadvertent reference to taking a lie detector test, and the trial court committed reversible error in denying appellant’s motion for mistrial. Accordingly, we reverse and remand for a new trial.
JUDGMENT OF THE COURT OF SPECIAL APPEALS REVERSED AND CASE REMANDED TO THAT COURT WITH INSTRUCTIONS TO REVERSE THE JUDGMENT OF THE CIRCUIT COURT FOR CAROLINE COUNTY AND REMAND TO THAT COURT FOR A NEW TRIAL. COSTS TO BE PAID BY APPELLEE.
DAVIDSON, J., concurs in the result.
