Aftеr a trial in Superior Court, Somerset County, the jury adjudged the defendant, Clinton Trafton, guilty of theft by unauthorized taking or transfer, 17-A M.R.S.A. § 353 (1980 Supp.). The defendant brings this appeal from the judgment entered on the verdict.
We sustain the appeal.
On May 8, 1979, Stanley McGray, owner of a gas station in Skоwhegan, had in a cracker box six bank bags containing between $8,000 and $10,000. That evening McGray left Chuck Robins, Jr., alone with the box of money in McGray’s van. The next morning, May 9, McGray took the box to his gas station. The defendant, as had been his habit for two or three months, met McGray at the gas station. Nobody else entered the station building. McGray left the defendant alone in the station for twenty minutes with the box. Upon McGray’s return, the defendant left. The evidence shows that later that day McGray reported to the police the theft of one bank bag containing approximately $1,000, and stated that the money might have been taken the previous evening. On May 10, McGray told the police that all six bags had been in the box at the gas station the morning of May 9th.
In addition to McGray, two other witnesses testified for the State. Horace Libby’s testimony was thoroughly impeached by three other witnesses. Douglas Beane testified to a conversation with the defendant as fоllows (in pertinent part):
Q. About that time did you have occasion to talk to Clinton Trafton?
*1322 A. Some time during June.
A. I said, why would [McGray] want you arrested. He said [McGray] claims I took some money up there and I didn’t do it. He said [McGray] offered to give me a hundred dollars to take a lie detector test. I said, why don’t you—
[Defense Counsel]: Objection.
The Court: Overruled.
A. So I said, I would take the lie detector test.
[Defense Counsel]: Objection.
[Discussion at side bar. Objection overruled.]
A. And I said if you didn’t take the money it will prove you’re not guilty and there’s nothing to worry about.
Q. And what did the Defendant say?
A. No, he didn’t want to take it and wanted to know if [McGray] would talk. ... He said, maybe [McGray will] let me pay him back so much each week.
Before Beane left the stand, the defense counsel asked for curative instructions to explain that lie detector tests will not necessarily establish guilt or innocence. The trial court refused this request.
At the conclusion of McGray’s testimony, the defense counsel attempted to ask McGray about a 1975 conviction for simple larceny, but was unable properly to formulate the question. 1 Defense counsel then asked for the right to rеcall McGray, to which the trial court replied “You have that right anyway.” When the defense counsel later attempted to recall McGray to ask about his prior conviction, the trial court refused to allow him to do so, stating thаt the prejudice to the State’s case would significantly outweigh the probative value of that evidence.
I
The defendant argues that the trial court erred by allowing Beane to testify about the defendant’s unwillingness to take a lie detector test.
We agree.
Both the results of polygraph tests and a party’s willingness or unwillingness to take such a test are inadmissible.
State v. Mower,
Me.,
The State argues that
State v. Mitchell,
Me.,
Finally, the trial court’s ruling emphasized that it was the defendant, in his out-of-court conversation with Beane, who brought up the subject of lie detector tests. In some circumstances, after a defendant has introduced testimony
at trial
regarding his willingness to take a lie detector test, the Stаte may be allowed to rebut with evidence of the defendant’s unwillingness to take such a test.
State v. Fox,
II
The defendant argues that the trial court erred in refusing to allow counsel to recall McGray in order to question him about his prior conviction for simple larceny.
We agree.
The trial court erred by refusing to allow the recall of McGray. It is true thаt a trial court has discretion in deciding whether to allow the recall of a witness.
See
M.R.Evid. 611(a);
State v. Kingsbury,
Me.,
We must delvе further, however, since the trial court did not indicate at that time how it would rule on the admissibility of evidence of McGray’s prior larceny conviction. Thus, even if defense counsel had been permitted to recall McGray, the trial court might have ruled to exclude evidence of the prior conviction. If the trial court could properly have excluded that evidence, the failure to allow the recall of McGray might be deemed harmless error.
We find thаt the trial court could not have properly excluded evidence of McGray’s prior larceny conviction. Under M.R.Evid. 609(a)
3
evidence of a prior conviction involving dishonesty or false statement is admissible to attack a witness’s
*1324
credibility if the probative value of the evidence outweighs the prejudicial effect to the defendant. The crime of larceny involves dishonesty or false statement.
State v. Charest,
Me.,
The State argues that the trial court could have excluded the conviction under M.R.Evid. 403.
4
Whether Rule 403 may be applied to exclude evidence of a prior conviction used to impeach a prosecution witness, or whether Rule 609 is the exclusive rule to be applied to such situations, is an open question.
5
Assuming, without deciding, that Rule 403 was appliсable, then the trial court could properly have excluded evidence of the conviction only if the danger of unfair prejudice
substantially
outweighed its probative value. Prejudice, in this context, means an undue tendency to move the tribunal to decide on an improper basis.
State v. Linnell,
Me.,
The evidence supporting a conviction in the instant case is far from overwhelming; the credibility of the State’s chief witness, McGray, was crucial. Also, the clear intent of Rule 609(a) is to admit all convictions of prоsecution witnesses which fall within the terms of the rule.
See
R. Field and P. Murray,
Maine Evidence
§ 609.1 (1976). A general policy of Maine’s rules of evidence is that any doubt regarding the admissibility of evidence be resolved in the defendant’s favor.
State v. Heald,
Me.,
Since we find admission of the evidence of the defendant’s unwillingness to submit to a polygraph examination to be reversible error, we need not decide whether the failure to allow McGray to be recalled would alone be reversible error. We discuss the latter issue because of the likelihood that it will arise agаin should there be a new trial.
The entry is:
Judgment vacated. Remanded to Superi- or Court for further proceedings consistent with the opinion herein.
All concurring.
Notes
. For a discussion of proper methods of impeaching a witness by evidence of prior cоnvictions, see
State v. Toppi,
Me.,
. The State does not argue that polygraph examinations have “reached the stage of scientific development and accuracy that permits admission of the result in evidence.”
State v. Mottram,
. M.R.Evid. 609(a) states:
General rule. For the purpose of attacking the credibility of a witness, evidence that he has been convicted of a crime is admissible but only if the crime (1) was рunishable by death or imprisonment for one year or more under the law under which he was convicted, or (2) involved dishonesty or false statement, *1324 regardless of the punishment. In either case admissibility shall depend upon a determination by thе court that the probative value of this evidence outweighs the prejudicial effect to the defendant.
. M.R.Evid. 403 states:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudicе, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
. The original Advisory Committee Note to F.R.Evid. 403 states that it is a guide for situations “for which no sрecific rules have been formulated.”
