Dissenting Opinion by
Hoffman, J.:I dissent from the Majority holding that the fact that the district attorney who prosecuted this case also represented the victim in a civil suit against the defendant arising out of the same transaction does not require a reversal of the appellant’s conviction.
Section 1.2(a) of the ABA Standards For Criminal Justice, Standards Relating To The Prosecution Function (Approved Draft, 1971) provides that “[a] prosecutor should avoid the appearance or reality of a conflict of interest with respect to his official duties.”1 The Majority and the court below recognize that the facts of the instant case, wherein the prosecuting attorney also represented the victim in a civil suit based on the alleged aggravated assault, potentially represent a conflict of interest. Both, however, refuse to grant a new trial because no specific prejudice has been uncovered by the appellant. As the lower court stated in its thorough opinion, “ [a] bsent some proof that the Assistant District Attorney’s conduct somehow deprived the defendant of *44a fair and impartial trial, there is no reason to suppose a properly counseled defendant was adversely affected by reason of the Assistant District Attorney’s dual representation.”
Initially, I agree with the Majority that the ABA standards generally are standards of conduct, not legal principles that are necessarily binding on our Court. See Commonwealth v. McNeal, 456 Pa. 394, 319 A. 2d 669 (1974). Our Supreme Court has, however, frequently relied on those standards as the ratio decidendi in finding reversible error. See, e.g., Commonwealth v. Potter, 445 Pa. 284, 285 A. 2d 492 (1971) and its progeny.
The Majority requires the appellant to show that prejudice arose from the dual representation by the prosecutor. The situation is similar to dual representation of two criminal defendants by one attorney, a problem addressed in Commonwealth ex rel. Whitling v. Russell, 406 Pa. 45, 48, 176 A. 2d 641, 643 (1962): “Despite its recognition of the existence of a conflict of interest under the circumstances, the Superior Court stated that it was appellant’s burden to show ‘that the conflict of interest resulted in such ineffective and improper representation as to result in basic and fundamental error’ and, in the instant situation, appellant had not sustained this burden. With that conclusion we cannot agree.
“If, in the representation of more than one defendant, a conflict of interest arises, the mere existence of such a conflict vitiates the proceedings, even though no actual harm results. The potentiality that such harm may result, rather than that such harm did result, furnishes the appropriate criterion.”
Neither the Majority nor the court below considers the potential for prejudice in the instant ease. I believe, however, that such a situation is ripe with potential prejudice not easily discovered by an appellant or by an appellate court.
*45Courts frequently articulate the lofty role that our society requires of a prosecuting attorney: “. . . in the performance of his duties, the law grants to the district attorney wide discretion in the exercise of which he acts in a judicial capacity.” Commonwealth ex rel. Specter v. Martin, 426 Pa. 102, 114, 232 A. 2d 729, 736 (1967). “The prosecutor is both an administrator of justice and an advocate; he must exercise sound discretion in the performance of his functions.” ABA Standards, supra, §1.1 (b), cited in Commonwealth v. Potter, supra, at 287, 285 A. 2d at 494. In our society, unlike many European systems of justice,2 we entrust vast discretion to the prosecutor in deciding which cases to pursue, what crimes to charge, and how to allocate limited resources. See, e.g., Breitel, Controls in Criminal Law Enforcement, 27 U. Chi. L. Rev. 427 (1960), wherein Judge Breitel argues that absent such discretion, our system of laws would be unmanageable; cf. Freedman, The Professional Responsibility of the Prosecuting Attorney, 55 Geo. L. J. 1030 (1967), wherein the author argues that such discretion is easily abused by a prosecutor who wishes to pursue a personal vendetta. See also, United States v. Cox, 342 F. 2d 167 (5th Cir. 1965).
One difficulty presented by such wide discretion is the fact that a prosecutor’s decision-making process is *46almost never reviewable by an appellate court. By its very nature, discretion is a subjective exercise; seldom is the motive for decision on record. Cf. Oyler v. Boles, 368 U.S. 448 (1962); but see, People v. Gray, 254 Cal. App. 2d 256, 63 Cal. Rptr. 211 (1967). Our society can tolerate a system that allows such an accretion of power despite the limited ability to review the decision-making process because we charge the district attorney or prosecuting attorney with a high ethical standard. That standard— the exercise of his “judicial capacity” — is breached not only by actual conflict of interest, but also by actions which have the appearance of conflict of interest.
Hence, in the instant case, neither this Court nor the appellant can know how or if the district attorney’s decision to prosecute was influenced by his representation of the victim in a civil suit. The situation is too ripe, however, with potential abuse: an attorney would be hard-pressed to abandon prosecution of a defendant when a criminal conviction would be proof of the alleged tort in the civil suit; the attorney would be free to use public resources to rout out additional evidence against the criminal defendant, a pursuit based not necessarily on the prosecutor’s view of the social importance of the case, but solely on the private interest which he and his client have in the case. A defendant does not have a right not to be prosecuted; he does, however, have a right to have his case reviewed by an administrator of justice with his mind on the public purpose, not by an advocate whose judgment may be blurred by subjective reasons.
I do not suggest that the attorney in the instant case abused his prosecutorial discretion. However, because of the subjective nature of the decision and the potential for abuse, I would reverse the appellant’s conviction and order a new trial.

See also, Code of Professional Responsibility, Canon 9: “A lawyer should avoid even the appearance of professional impropriety.” EC 9-3: “After a lawyer leaves judicial office or other public employment, he should not accept employment in connection with any matter in which he had substantial responsibility prior to his leaving, since to accept employment would give the appearance of impropriety even if none exists.” DR 9-101 (B): “A lawyer shall not accept private employment in a matter in which he had substantial responsibility while he was a public employee.”
. See, e.g., Davis, Discretionary Justice, at 194-95: “The most important difference between the German system and the American system is this: Whenever the evidence that the defendant has committed a serious crime is reasonably clear and the law is not in doubt, the German prosecutor, unlike the American prosecutor, is without discretionary power to withhold prosecution. This means that selective enforcement, a major feature of the American system, is almost wholly absent from the German system. The German prosecutor does not withhold prosecution for such reasons as that he thinks the statute overreaches, that justice requires withholding enforcement because of special circumstances, that the statute ought to he enforced against some violators and not others, that he lacks time for bringing marginal prosecution. . . .”
