M.F. CAVANAGH, J.

Defendant was convicted May 16, 1974, of conspiracy to burn a dwelling house, MCLA 750.72; MSA 28.267, and MCLA 750.157a; MSA 28.354(1), after a four-day jury trial. Defendant was sentenced on June 5, 1974, to a prison term of 1-1/2 to 20 years. Defendant appeals his conviction as of right under GCR 1963, 806.1.

Defendants Leonard Hale, Verlin Thomas, and Herman Handshoe were charged by information with the crime of conspiring to burn the defendant's mobile home. At the preliminary examination, charges against Verlin Thomas were dismissed for lack of evidence. Later, the trial court granted a motion to quash the information against Herman Handshoe for lack of sufficient admissible evidence to connect him with the conspiracy. Upon conviction, defendant took an appeal to this Court, which remanded the case to the circuit court for an evidentiary hearing on a motion for a new trial.

Pursuant to this Court's remand, the defendant brought a motion for a new trial before trial court Judge Gordon Britten on the basis of recanting testimony from Judi Minder, the prosecution's principal trial witness. Defense counsel first brought a motion for bond pending appeal before Judge Britten. At the bond motion, Judge Britten asked defense counsel whether counsel was aware that Mrs. Minder had taken a polygraph examination before the trial. Defense counsel answered negatively, but the prosecution offered that Mrs. Minder had, indeed, taken such a test and had "passed" it. The defendant then moved to disqualify Judge Britten from hearing the motion for a new trial on the ground of Judge Britten's prejudicial knowledge of Judi Minder's pre-trial polygraph examination.

Judge Britten refused to hear the disqualification motion, claiming that he had no jurisdiction. Judge James G. Fleming heard and denied the motion because "[n]o factual showing of actual prejudice had been made".

The motion for a new trial was subsequently brought before Judge Britten. Judi Minder gave extensive testimony that denied the substance of her trial testimony, stating that her motive had been to seek revenge upon the defendant because of his infidelity. Judge Britten denied the motion for a new trial, deeming her recanting affidavits and testimony to be contradictory and not credible.

Upon denial of the new trial motion, defendant brought his second appeal, claiming error on several grounds. Our disposition of the case allows us to respond to but one of the defendant's claims of error.

The Michigan courts have held that " * * * absent a showing of actual prejudice or bias from the record, a trial judge has the right to hear a case to its conclusion". People v Irwin, 47 Mich. App. 608, 609; 209 N.W.2d 718, 719 (1973). The defendant claims that although Judge Britten didn't refer to the polygraph examination of Judi Minder in his decision, the knowledge of the results may have so much prejudiced his decision that he should have been disqualified. We agree.

The courts of this state have consistently held that results of polygraph examinations or reference to them are inadmissible evidence. People v Frechette, 380 Mich. 64; 155 N.W.2d 830 (1968), People v Becker, 300 Mich. 562; 2 N.W.2d 503 (1942). There have been recent challenges to the rule, People v Levelston, 54 Mich. App. 477; 221 N.W.2d 235 (1974), People v Barbara, (Docket No. 15815, March 23, 1973 [unreported order]), lv granted, 391 Mich. 761 (1974), but this Court has been careful to exclude usage of polygraph evidence in an ever-widening circle of circumstances. In addition to criminal trials, use of polygraph results has been forbidden with respect to competency hearings, presentence reports, motions for a new trial, sentencing proceedings, and civil and administrative proceedings. People v Dockery, 65 Mich. App. 600; 237 N.W.2d 575 (1975), People v Liddell, 63 Mich. App. 491; 234 N.W.2d 669 (1975), People v Allen, 49 Mich. App. 148; 211 N.W.2d 533 (1973), People v Sinclair, 21 Mich. App. 255; 175 N.W.2d 893 (1970).

In People v Allen, 49 Mich. App. 148; 211 N.W.2d 533 (1973), at the sentencing hearing, the trial judge referred to the successful polygraph examination of the prosecution's principal witness and challenged the defendant to submit to a polygraph examination. The defendant refused. Before a subsequent motion for a new trial, the defendant moved to disqualify the trial judge because of his knowledge of the polygraph results. The trial judge denied both motions. This Court, in reliance on People v Sinclair, supra, stated:

"In defendant's case here it is not clear from the record below whether the trial court considered the polygraph test results in denying the motions for a new trial, but his awareness of them from the sentencing certainly suggests he might have. We must, therefore, remand this case for a rehearing of defendant's motion for a new trial before a different trial judge. We believe that Sinclair, supra, provides us with no other realistic alternative." 49 Mich. App. 151; 211 N.W.2d 535.

We cannot say that Judge Britten's knowledge of Judi Minder's polygraph results was not prejudicial. At the hearing on the motion for a new trial, Judi Minder, whose testimony formed the critical elements of the prosecution's case, recanted all of her trial testimony that incriminated the defendant. Her credibility was the sole issue. At the motion for bond, Judge Britten affirmatively sought the polygraph information, which was clearly unrelated to the issues on the bond motion. Moreover, Judge Britten has previously indicated his belief in the trustworthiness of polygraph examinations. See People v Bovee, 60 Mich. App. 727, 728; 231 N.W.2d 529 (1975). While the trial judge did not refer to Mrs. Minder's polygraph results at the subsequent hearing on the motion for a new trial or in his opinion denying that motion, People v Towns, 69 Mich. App. 475; 245 N.W.2d 97 (1976), indicates that even judicial disclaimers of being influenced by polygraph information are nullified by People v Allen:

"While there is nothing in the record to clearly indicate that the defendant's sentence was based on the trial judge's belief in Elmore's [the prosecution's principal witness] polygraph results, we cannot help but wonder what effect the judge's knowledge of the test results had on defendant's sentence." 49 Mich. App. 152; 211 N.W.2d 536, quoted in People v Towns, 69 Mich. App. 478; 245 N.W.2d 99.

Remanded for a new hearing on the motion for a new trial before a different trial judge. This Court retains jurisdiction.

BEASLEY, J., concurs in the result.
