(concurring in the result). A review of the record leads me to the conclusion that the prosecutor’s simple reference to an arrest not resulting in a conviction did not constitute reversible error. However, the prosecutor’s use of a misdemeanor conviction for impeachment purposes causes me grave concern. This important issue has received too little attention by the courts of this state. The admission of a misdemeanor conviction for being a disorderly person in a murder trial to test the defendant’s credibility reveals to this writer a clear case where the prejudicial effect of evidence outweighs its relevancy. I, therefore, concur in the result, but for a different reason.

It is significant that the error based upon People v Brocato, 17, Mich App 277 (1969), was not raised by defendant. This failure to preserve the issue for appeal precludes reversal unless preserved by the Court sua sponte to prevent a miscarriage of justice. People v Degraffenreid, 19 Mich App 702 (1969). Dependency upon this concept requires a search of the record to substantiate an injustice before a reversal is appropriate and must be distinguished from errors which themselves constitute reversible error.1

The prosecutor’s attempt to impeach the defendant’s credibility involved a series of questions regarding his prior criminal record. Each of these *704questions preceding the impermissible reference to an arrest were prefaced by the phrase "[have you] ever been arrested and convicted(Emphasis added.) This format clearly satisfies Brocato and its progeny. The prosecutor then asked defendant whether he had ever been arrested for robbery in Trenton, New Jersey. This single impermissible question regarding an arrest not culminating in a conviction was not further pursued after it was answered in the negative. Subsequently, the prosecutor questioned the defendant in a conclusionary manner as to whether his only arrest and conviction was limited to the unarmed robbery elicited during earlier testimony. With an affirmative answer the prosecutor terminated his questions regarding prior crimes and concluded his cross-examination by a single question asking defendant whether he wanted to reconsider his answer.

In this context, no scheme, design, or concerted effort by the prosecutor to place undue emphasis upon this arrest or prejudice defendant by its injection in the case is revealed.2 The prosecutor’s single improper reference must be viewed as an inadvertent error similar to that found in People v Peay, 37 Mich App 414 (1971). Therein the prosecutor’s references to arrests based upon an incorrect "rap sheet” were viewed as an inadvertent error. As in the present case, the defendant in Peay raised no objection. The Court’s conclusion in Peay that defendant was not prejudiced by the prosecutor’s error is equally applicable to the present case. The error below was further mitigated by the trial judge’s charge to the jury that they were to disregard any reference by the prosecutor to crimes for which the defendant denied conviction or the prosecutor had no proof of conviction. This *705error, permitted without objection, fails to offend one’s sense of justice and a consideration of the entire record fails to disclose a miscarriage of justice.3

The prosecutor’s use of a misdemeanor conviction4 for purposes of impeachment was objected to by defendant and presents the crucial issue in the present appeal. The impetus for impeaching witnesses and defendants via prior convictions flows from statutory sanction. MCLA 600.2158; MSA 27A.2158. The permissible scope of such impeachment is not defined in the statute since it merely provides:

"[The] conviction of crime, may be shown for the purpose of drawing in question the credibility of such witness * * * .”5 (Emphasis added.)

The failure of the statute to further define the types of crimes admissible for purposes of testing a witness’ credibility leaves a void to be filled in by statutory interpretation.

The proper construction of this statute must take cognizance of the fact that the statute is to be strictly construed6 and the admissibility of convictions like all other evidence depends upon a test which balances its relevancy and prejudicial effect. A construction permitting the admissibility of all crimes as a matter of law7 would effectively under*706mine the purpose of these concepts. This construction is further barred by the permissive nature of the statute as recently recognized by this Court in People v Farrar, 36 Mich App 294 (1971). The Farrar Court based its conclusion upon the construction of a similar statute found in Luck v United States, 121 US App DC 151; 348 F2d 763 (1965).8 Since the statute states that a conviction "may” as opposed to "shall” be admitted, the Luck Court held that the admissibility of such convictions fell within the trial judge’s discretion. This approach preserves the evidentiary test in which admissibility is determined by balancing the probative value and prejudicial effect of proffered convictions. The Farrar Court’s adoption of this discretionary rule provides defendants with the only protection against being intimidated into relinquishing the right to testify in their own behalf.

The present case provides us with a timely opportunity to reaffirm this doctrine and establish some needed guidelines.

The trial judge responded to defendant’s objection to the misdemeanor conviction by concluding that (1) there was no distinction between felonies and misdemeanors, and (2) the prosecutor could use misdemeanors if they were convictions. It is difficult to determine from this conclusion whether the trial judge failed to exercise his discretion believing that admission was required by the statute or exercised his discretion and affirmatively admitted the misdemeanor conviction. If the ad*707mission is accurately portrayed as the trial judge’s failure to exercise his discretion, such inaction ignores Farrar and constitutes error. If the admission resulted from an exercise of discretion, the interjection of a conviction for being a disorderly person in a murder trial creates an aura of prejudice requiring our further consideration.

The concept of judicial discretion is indispensable to the prudent administration of trials. But what is "judicial discretion”? There are many definitions of this elusive creature, but in this writer’s opinion the one authored by Lord Mansfield has really never been improved upon:

"Discretion when applied to a court of justice means sound discretion guided by law. It must be governed by rule, not humor; it must not be arbitrary, vague, and fanciful, but legal and regular."9 (Emphasis added.)

The proper exercise of discretion pursuant to this formula can be guaranteed only by the use of guidelines. A majority of these guidelines are found in Gordon v United States, 127 US App DC 343; 383 F2d 936 (1967). They are exhaustively set forth by this Court in People v Farrar, supra, and need not be reiterated.

The present case involving a specific challenge to the admission of misdemeanors necessitates further direction by this Court. A distinction between felonies and misdemeanors in which only felonies are admitted cannot be drawn as a finite guideline. Such an approach would ignore two important considerations. Crimes involving credibility are the most appropriate for impeachment purposes because they have the highest correlation *708with relevancy.10 This category of crimes is followed closely by crimes involving moral turpitude. The interrelationship of these factors with the classifications of felony and misdemeanor creates a variety of combinations in which the relevancy and prejudicial effect will vary. A linear scale measuring relevancy and prejudice will find felonies involving credibility at the end with the highest relevancy — lowest prejudicial effect and simple misdemeanors at the opposite end with the lowest relevancy — highest prejudicial effect. Without attempting to consider the merits of each combination, it is clear that the admissibility of prior convictions constitutes a greater danger of error as they approach the category of simple misdemeanors.

The present case involving a conviction for being a disorderly person in a murder trial reveals an example of the extreme end of the scale where admission should be denied.11 This type of conviction merely invites the jury to convict the defendant because his prior misconduct indicates that he is a "lawbreaker” with a higher propensity to break the law again. Although misdemeanor convictions are permitted in civil cases,12 the nature of *709a criminal trial with its inherent differences and fundamental protections necessitates a different rule.

Defendant’s murder trial turned exclusively upon the issue of self defense. Since the credibility of defendant and the witnesses testifying provided the only vehicle for resolving this issue, the admission of evidence was critical. To prevent the impeachment process from circumscribing the justice out of the criminal judicial system, the admission of simple misdemeanors to test a defendant’s credibility should be considered suspect. The trial judge’s admission of this misdemeanor must be considered error.

Since the precise basis for the admission of defendant’s misdemeanor conviction does not appear on the record, both types of conduct had to be considered. If the admission was achieved for failure of the trial judge to exercise his discretion, error resulted. If the admission was achieved pursuant to an exercise of the trial judge’s discretion, it must be considered erroneous as being inconsistent with fundamental evidentiary standards. In either event, we cannot conclude that the jury would have reached the same decision had the error not occurred. Cf. People v Moore, 39 Mich App 329, 336 (1972). For this reason I would reverse defendant’s conviction and remand for a new trial.

On the evening of August 22, 1970, defendant and the deceased, Nathaniel Douglas, were in a bar in Jackson. The defendant and the deceased got into an argument over a loan. A fight ensued. The force of the defendant’s blows made the deceased back up through a pair of swinging doors. At this time the defendant allegedly pulled a gun and shot the deceased, fatally injuring him.

At the trial four witnesses, who were present at the bar at the time of the shooting, testified that the defendant shot the decedent as he was backing up. The defendant testified that he killed the decedent unintentionally and was acting in self defense.

*701The defendant was convicted by a jury of second degree murder, a violation of MCLA 750.317; MSA 28.549. Defendant was sentenced by the court to serve from 15 to 25 years imprisonment.

A review of the record discloses an error which was not raised on appeal. However, since this error requires reversal, it is within the power of this Court to consider this issue and to avoid a miscarriage of justice. People v Brocato, 17 Mich App 277. (1969); People v Mattice, 38 Mich App 333 (1972).

During the trial, the prosecutor, while questioning the defendant, asked him if he had been arrested for a robbery in Trenton, New Jersey. Even after the defendant had denied this, the prosecutor pursued this line of questioning by asking him if he wanted to reconsider the answer. Also, in the course of questioning the defendant with reference to misdemeanor violations, the prosecutor managed to work into the record the matter of an incident in Jersey City wherein it appears the defendant was arrested as a disorderly person but was not convicted, according to the testimony.

This Court stated in People v Brocato, supra, 302-303:

"We now hold that a defendant testifying at his own trial may not be asked if he has been arrested or charged with crime, where the arrest or charge has not resulted in a conviction and where the only purpose of the questions is to impeach the defendant’s credibility as a witness. Where credibility is the only issue, the probative value of arrests and charges, unsubstantiated by a conviction, is slight at best. When weighed against the great danger that the jury, despite careful instructions, might misapply such evidence, the scales of justice tip in favor of exclusion. United States v Beno, 324 F2d 582 (CA 2, 1963).”

*702The holding of this Court in Brocato is applicable to the present case. The sole issue here for the jury to decide was which witnesses were to be believed. It was a matter of the credibility of the witnesses which is the essence of the holding in Brocato, supra. Furthermore, in the instant case, the apparent purpose of the prosecutor’s questioning was obviously to impeach the defendant’s credibility.

The facts here are distinguishable from those present in People v Osgood, 24 Mich App 705 (1970). In Osgood the prosecutor asked the defendant if he had been convicted. In the present case the defendant was specifically asked if he had been arrested. Even when the answer was in the negative the prosecutor continued to pursue the area of arrest only.

People v Peay, 37 Mich App 414 (1971), is also distinguishable from the present case. There the trial court allowed the prosecution to question the defendant concerning a prior arrest but it was shown on appeal that this was due to an inadvertent error. Further, the prosecutor in that case immediately ceased to question the defendant after he had denied ever being arrested for the particular crime.

In this case the prosecutor, by the innuendo of the language he employed, did not cease this line of attack. As a result I believe a manifest injustice resulted, necessitating reversal.

Further, under the facts of this case, admission of proof of conviction on a charge of disorderly person on the issue of defendant’s credibility in a first-degree murder case created a situation where the danger of prejudice exceeded the probative value of this line of inquiry. Hence I conclude that the admission of proof of this misdemeanor convic*703tion must be considered error for the reasons and on the basis of the authorities cited by Judge Bronson in his opinion.

Reversed and remanded for new trial.

(dissenting). I would affirm defendant’s conviction. The basis for reversal raised by Judge Targonski is raised sua sponte on the ground that reversal is required to avoid a miscarriage of justice. I find no miscarriage of justice. The record in this case is replete with evidence that is clear, convincing, and sufficient to sustain the conviction.

*710Likewise, I dissent from the grounds for reversal stated by Judge Bronson. The error he finds sufficient for reversal was properly preserved for appellate review. While I agree it is error for a trial court to fail to exercise its sound discretion as to the admissibility into evidence of prior misdemeanor convictions without regard to the relevance, probative value, and prejudicial effect of the proffered misdemeanor convictions, I find the error on the record in this case to be harmless error. The combination of the error raised sua sponte and the error properly preserved does not provide sufficient grounds for reversal of the conviction.

I vote to affirm.
