Opinion by
Mr. Justice Eagen,On January 30, 1963, Charles Negri was convicted by a jury of murder in the first degree, and a sentence of life imprisonment was imposed on June 17, 1963. Thereafter, an appeal was filed with this Court, and on March 17, 1964, we affirmed the judgment of sentence, 414 Pa. 21, 198 A. 2d 595 (1964). Subsequently, on June 22, 1964, decisions were filed by the Supreme Court of the United States in the cases of Escobedo v. Illinois, 378 U.S. 478 (1964), and Jackson v. Denno, 378 U.S. 368 (1964). In order to consider and evaluate the application of these rulings on the present case, we ordered reargument.
During the trial, a confession, given by Negri to the police following his arrest and while he was without counsel, was admitted in evidence. It was established through the testimony of the police officers who participated in the interrogation that Negri was not warned of his right to remain silent, nor was he advised *120that he could then have the assistance of counsel. It was further established that, during this period, Negri did not request the assistance of counsel.
When the decision in Escobedo was announced and studied, we construed its ruling to be limited to the particular facts of the case, and specifically so stated in Commonwealth ex rel. Linde v. Maroney, 416 Pa. 331, 206 A. 2d 288 (1965), and Commonwealth v. Patrick, 416 Pa. 437, 206 A. 2d 295 (1965), among others. As we interpreted the Escobedo opinion, it held that where a person in police custody is not warned of his constitutional right to remain silent during an accusatorial interrogation, it is necessary that he then be given the assistance of counsel to protect that right, if such assistance is requested. To us, the specific ruling of the case was clear, although, admittedly, dicta in the opinion did portend more revolutionary ramifications.
Our interpretation of the meaning of Escobedo was shared by other jurisdictions, both state and federal. See, Sturgis v. Maryland, 235 Md. 343, 201 A. 2d 681 (1964); Illinois v. Hartgraves, 31 Ill. 2d 375, 202 N.E. 2d 33 (1964), cert. denied, 380 U.S. 961, 85 S. Ct. 1104 (1965); People v. Donovan, 13 N.Y. 2d 148, 243 N.Y.S. 2d 841, 193 N.E. 2d 628 (1963); State v. Smith, 43 N.J. 67, 202 A. 2d 699 (1964), cert. denied, 379 U.S. 1005, 85 S. Ct. 731 (1965); Wansley v. (Commonwealth) Virginia, 205 Va. 412, 137 S.E. 2d 865 (1964), cert. denied, 380 U.S. 922, 85 S. Ct. 920 (1965); McQueen v. Maxwell, 177 Ohio St. 30, 201 N.E. 2d 701 (1964); Browne v. State, 24 Wis. 2d 491, 131 N.W. 2d 169 (1964), cert. denied, 379 U.S. 1004, 85 S. Ct. 730 (1965); United States ex rel. Townsend v. Ogilvie, 334 F. 2d 837 (7th Cir. 1964), cert. denied, 379 U.S. 984, 85 S. Ct. 683 (1985); and, Mitchell v. Stephens, 232 F. Supp. 497 (D.C. E.D. Ark. 1964).
However, other state and federal jurisdictions interpreted Escobedo differently, and reached another re-*121suit. These concluded that the assistance of counsel must be afforded the accused (if not intelligently and understanding^ waived) at the interrogation level; otherwise, any incriminating statements obtained are constitutionally invalid and inadmissible at trial, even in the absence of a request for such assistance. See, People v. Dorado, 42 Cal. Rptr. 169, 398 P. 2d 361 (1965), cert. denied, 381 U.S. 946, 85 S. Ct. 1793, 33 L.W. 3382 (1965); Oregon v. Neely, 395 P. 2d 557 (Ore. 1964); Commonwealth v. McCarthy, 200 N.E. 2d 264 (Mass. 1964); Campbell v. Tennessee, 384 S.W. 2d 4 (Tenn. 1964); and, United States v. Guerra, 334 F. 2d 138 (2d Cir. 1964), cert. denied, 379 U.S. 936, 85 S. Ct. 337 (1964).
Thus, the law on the point in question is in a state of serious confusion with no apparent hope of enlightment from the Supreme Court of the United States, in view of its action in refusing certiorari in cases reaching conflicting results. Compare People v. Dorado, supra, with Illinois v. Hartgraves, supra, and United States v. Guerra, supra, with United States ex rel. Townsend v. Ogilvie, supra.
Coupled with this inaction, the recent (May 20, 1965) decision of the distinguished United States Court of Appeals for the Third Circuit in the companion cases of United States ex rel. Russo v. New Jersey, and United States ex rel. Bisignano v. New Jersey, 351 F. 2d 429 (3d Cir. 1965), takes on added importance. That court, speaking through Chief Judge Biggs, elected to join the jurisdictions holding that no request by the accused is necessary to impose upon the interrogating police the duty to furnish the assistance of counsel in this situation in the absence of a warning to remain silent or an intelligent and understanding waiver. Obviously, this decision creates a serious problem for this Court, and jeopardizes the finality of our judgments in relevant cases.
*122While recognizing that in cases involving federal questions the Supreme Court of the United States is the ultimate arbiter, in view of the widespread confusion in this area of the law and the failure of the Supreme Court to clarify it, the decision of the Third Circuit Court of Appeals is on this matter, for all practical purposes, the ultimate forum in Pennsylvania. If the Pennsylvania courts refuse to .abide by its conclusions, then the individual to whom we deny relief need only to “walk across the street” to gain a different result. Such an unfortunate situation would cause disrespect for the law. It would also result in adding to the already burdensome problems of the Commonwealth’s trial courts, which look to us for guidance. Finality of judgments would become illusory, disposition of litigation prolonged for years, the business of the courts unnecessarily clogged, and justice intolerably delayed and frequently denied.
Consequently, in order to alleviate and correct a regrettable situation, the clear indication for this Court is to accept and follow the decision of the Third Circuit on this matter until some further word is spoken by the Supreme Court of the United States.
Notwithstanding this result, however, the reasoning in two recent decisions of the Supreme Court of the United States,1 denying retrospective effect to the decision in Mapp v. Ohio, 367 U.S. 643 (1961), raises serious questions as to the retrospectivity of the ruling in Escobedo v. Illinois.2
*123The wide-sweeping effect of the decision in Linlcletter, supra, note 1, seems to abandon once and for all the Blackstonian concept that judges do not make, but merely discover, the law, and that overruled decisions were never the law, but merely erroneously declared concepts. And, having hurdled the philosophical obstacle, the Court continues, 381 U.S. at 629, 85 S. Ct. at 1737, 33 L.W. at 4579: “. . . [W]e believe that the Constitution neither prohibits nor requires retrospective effect. As Justice Cakdozo said, *We think the Federal Constitution has no voice upon the subject.’ ” (Citing Great Northern Ry. Co. v. Sunburst Oil & Refining Co., 287 U.S. 358, 364 (1932), as authority in a footnote). The approach then is to “weigh the merits and demerits in each case by looking to the prior history of the rule in question, its purpose and effect, and whether retrospective operation will further or retard its operation.” 381 U.S. at 629, 85 S. Ct. at 1738, 33 L.W. at 4579.
The guarantee against a denial of the right to the assistance of counsel, embodied in the Sixth Amendment, is obligatory upon the states only insofar as the denial violates the protection of the Due Process Clause of the Fourteenth Amendment. Due process of law has always been a term difficult to define with exactitude, and is said to be that process which assures to the accused a fair trial within the “concept of ordered liberty”. See, Palko v. Connecticut, 302 U.S. 319 (1937). The right to counsel at pretrial stages inherent in this concept was enunciated in Crooker v. California, 357 U.S. 433 (1958), and Cicenia v. LaGay, 357 U.S. 504 (1958), which denied that there was an absolute right to counsel prior to trial. The test applied was whether the accused suffered any prejudice from the failure to supply counsel at these stages, a *124test to be applied on an ad hoc basis. Then, in Escobedo v. Illinois, the Court found this ad hoc basis to be an unreliable method for the determination of Constitutional rights, and set out, by means of absolute standards, to give complete assurance that an accused would not be overborne. The decision in Escobedo, while not spelling out the Fifth Amendment,3 necessarily wraps the guarantees of the right to the assistance of counsel and the right to be free from compulsory self-incrimination into one package.4
What, then, is the purpose of the ruling in Escobedo? Crooker v. California, and Cicenia v. LaCay, supra, protect the accused from any prejudice arising out of the failure to afford counsel at an accusatory interrogation. Jackson v. Denno, supra, protects the accused from any use of a coerced confession. And the Fifth Amendment does not proscribe, even to federal courts, the use of voluntarily made self-incriminating statements, but only condemns compulsory self-incrimination. Therefore, the only function left to the ruling in Escobedo is to prevent the possibility of prejudice which an accused might not be able to prove at trial. This conclusion is somewhat akin to that of the California court in Lopez, supra, note 2, that the purpose was to prevent police practices which invite coerced confessions. The compelling ultimate conclusion, in either case, is that the Court was concerned with overbearing police tactics and possible abuses of individual rights.5
*125The issue in this case is markedly parallel with that decided in Linkletter v. Walker, supra, note 1, holding that Mapp v. Ohio, supra, was not to be applied retrospectively. The Court there said, 381 U.S. at 637, 85 S. Ct. at 1742, 33 L.W. at 4582, “ . . [T]he ruptured privacy of the victim’s homes and effects cannot be restored. Reparation comes too late.” In the same manner, it is too late to silence the tongues of those convicted persons who chose to unburden themselves of the secret of their guilt. The fact that the accused may not have known that he had a right to remain silent or that he had a right to the assistance of counsel does not in any way negate the fact that the statement was made voluntarily6 or that the probabili*126ty of truthfulness is very high.7 And, while the Fifth Amendment right is against compulsory self-incrimination, we do not think that an accused’s ignorance rises to such compulsion.
We do not think that the purpose of Escobedo was to ferret out unreliable or coerced confessions, any more than the purpose of Mapp was to deny admissibility to irrelevant or unprobative physical evidence. The identical purpose of each was to provide adequate assurance of police adherence to the constitutional principles inherent in due process, by denying fruit to the poisoned seed. See, Commonwealth ex rel. Wilson v. Rundle, 412 Pa. 109, 194 A. 2d 143 (1963).
Much as the Court was concerned with the “administration of justice and the integrity of the judicial process” in Linkletter v. Walker, 381 U.S. at 637, 85 S. Ct. at 1742, 33 L.W. at 4582, we are equally concerned, if not more so, over the resultant chaos which would arise out of a retrospective application of Escobedo. Hearings would have to be held to determine whether the required admonitions had been given (perhaps by interrogators long since deceased), and whether the constitutional rights had been intelligently and understandingly waived. And if it could be found that the confession should not have been admitted, then many guilty persons would go free, because the police had felt that it was unnecessary to preserve the testimony of the other witnesses and/or the actual physical evidence which it possessed. We cannot believe that such chaos was the intent of the Supreme Court of the United *127States when it deemed fit to announce a standard to protect against any possible overbearing upon the part of investigating police officers.
The actual retrospective applications of Griffin v. Illinois, 351 U.S. 12 (1956) (requiring states to furnish transcripts of the trial to indigents on appeal), Gideon v. Wainwright, 372 U.S. 335 (1963) (requiring the appointment of counsel in all state felony trials), and Jackson v. Denno, supra (requiring a preliminary determination of the voluntariness of a confession before the jury can hear it), are all inapplicable to the present situation, just as they were so declared in Mapp — illegal search and seizure situation. Each of those cases dealt with a fundamental right, the denial of which was likely to allow the conviction of an innocent man. Such is not the case in the Escobedo situation, where, by hypothesis, the evidence denied admissibility is an admittedly voluntary and truthful confession, which is rendered inadmissible not because the manner of securing it was likely to produce an unreliable confession, but because it was likely not to have been given at all if the accused had been assured that he could remain silent. We are not stating that this right is any less fundamental than the right to counsel at trial, etc., but just that it is of such character that its denial was not likely to bring about an unfair trial, i.e., one in which there was a substantial chance that an innocent person might have been convicted.
The further question is asked in Linkletter, whether a retrospective application will further or retard the purpose of the rule. In this situation, we think it would do neither, but, as above pointed out, would seriously retard the business of the courts. While the discharging of a multitude of prisoners which would result from a retrospective application of the ruling might have some shock value to inform interrogating police officers that the courts will not countenance further *128lapses, the interests of society in being secure from such an outflux heavily outweigh any additional emphasis of the seriousness of the ruling which might be obtained.8 The rule being aimed primarily at regulating-police conduct and at eliminating situations fraught only with the possibility of unprovable prejudice, we think that the proper administration of the court’s business and the security and peace of society demand that the ruling in Escobedo operate prospectively only.
In so stating, we recognize two incongruous features. First, the ruling in Escobedo necessarily operated with some degree of retrospectivity when it was applied to Danny Escobedo’s proceedings. This same problem arose in the Mapp — situation. However, assuming that there is no imperative requirement that all constitutional decisions be applied retrospectively and that there are good reasons for not doing so, the problem must be met as to where the line will be drawn.9 While recognizing that sometimes the drawing of a line may appear to be arbitrary, we think that the line drawn in Commonwealth ex rel. Wilson v. Rnndle, and Linkletter v. Walker, supra, is both workable and reasonable, i.e., that the ruling in Escobedo should apply only to those cases not final10 at the time it was announced. Second, the decision of the Third Circuit in United States ex rel. Russo v. New Jersey and United States ex rel. Bisignano v. New Jersey, su*129pra, of necessity applied the ruling of Escobedo retrospectively, since the cases there involved federal habeas corpus petitions challenging final state convictions. However, no explicit mention was made of the problem of retrospeetivity, and we assume, therefore, that the question did not arise in that court. While the inter-systematic problems which were presented by that decision prompted us to change our position regarding the necessity of a “request” for the assistance of counsel, we cannot defer to a position which was undiscussed and only inferentially applied by the Third Circuit.
Therefore, it is our considered opinion that, while the request for the assistance of counsel by a suspect during an accusatory investigation is not a conclusive factor in determining the admissibility of a confession under the ruling of Escobedo, such ruling should not be applied retrospectively to convictions finally sustained prior to the ruling of Escobedo v. Illinois, supra, on June 22, 1964. As applied to the present case, the conviction of Charles Negri was finally affirmed by this Court on March 17, 1964. No petition for certiorari was filed with the Supreme Court of the United States. While we granted reargument in order to determine the effect of Escobedo upon Negri’s conviction after the operative date, that factor is irrelevant in view of the conclusion herein reached that the decision has no effect upon the conviction. Consequently, the granting of reargument for such a purpose had no effect upon the finality of the conviction.
However, since the question of coercion in securing the confession is raised in this case, it is necessary to remand the record to the court of original jurisdiction for the purpose of conducting an independent hearing, as required under Jackson v. Denno, supra, to determine whether the confession was voluntarily and freely given. After said hearing, the court will file a report *130containing its findings and conclusions. See, Commonwealth ex rel. Gaito v. Maroney, 416 Pa. 199, 204 A. 2d 758 (1964), and Commonwealth v. Coyle, 415 Pa. 379, 203 A. 2d 782 (1964).
Record remanded with directions. Final decision reserved.
Mr. Justice Cohen dissents.Linkletter v. Walker, 381 U.S. 618, 85 S. Ct. 1731, 33 L.W. 4576 (1965), and Angelet v. Fay, 381 U.S. 654, 85 S. Ct. 1750, 33 L.W. 4587 (1965), both, delivered June 7, 1965.
The Supreme Court of California, in a companion case with People v. Dorado, 42 Cal. Rptr. 169, 398 P. 2d 361 (1965), denied retrospective application of the Escobedo ruling: In Re Lopez, 42 Cal. Rptr. 188, 398 P. 2d 380 (1965). So too, the United States Court of Appeals for the Seventh Circuit, relying upon Linkletter v. Walker, supra, note 1, denied retrospective application to the *123ruling in Escobedo: United States ex rel. Walden v. Pate, 350 F. 2d 240, 34 L.W. 2065 (7th Cir. 1965) (decided on July 27, 1965).
The Fifth Amendment protection against compulsory self-incrimination is also obligatory upon the states: Malloy v. Hogan, 378 U.S. 1 (1964).
See, Kurland, The Supreme Court, 1963 Term, 78 Harv. L. Rev. 143, 217-223 (1964).
As the court stated, 378 U.S. at 488-490: “We have learned the lesson of history, ancient and modern, that a system of criminal law enforcement which comes to depend on the ‘confession’ will, in the long run, be less reliable and more subject to abuses *125than a system which depends on extrinsic evidence independently secured through skillful investigation. As Dean Wigmore so wisely said: ‘{A]ny system, of administration w7t/ich permits the prosecution to trust habitually to compulsory self-disclosure as a source of proof must itself suffer morally thereby. The inclination develops to rely mainly upon such evidence, and to be satisfied with an incomplete investigation of the other sources. The exercise of the power to extract answers begets a forgetfulness of the just limitations of that power. The simple and peaceful process of questioning breeds a readiness to resort to bullying and to physical force and torture. If there is a right to an answer, there soon seems to be a right to the expected answer, — that is, to a confession of guilt. Thus the legitimate use grows into the unjust abuse; ultimately, the inocent are jeopardized by the encroachments of a bad system. Such seems to have been the course of experience in those legal systems where the privilege was not recognized.’ 8 Wigmore, Evidence (3d ed. 1940), 309. (Emphasis in original.) This Court also has recognized that ‘history amply shows that confessions have often been extorted to save law eforcement officials the trouble and effort of obtaining valid and independent evidence. . . .’ [Citing a case.]” (Footnotes omitted.)
We assume for these purposes that the statement was voluntarily made. If it was not, the convicted person’s remedy lies in an attack through Jaclcson v. Denno, supra (already declared to be retrospective in Commonwealth ex rel. Butler v. Rundle, 416 Pa. 321, 206 A. 2d 283 (1965), and Commonwealth ex rel. Linde v. Maroney, supra), not through Escobedo.
As observed by the California court in Lopez, supra, note 2, 398 P. 2d at 387 (footnote 12) : “The [Supreme C]ourt [of the United States in Escobedo v. Illinois] also indicates that the presence of counsel at interrogation will mate meaningful the accused’s right to remain silent. This reason does not relate to the erroneous conviction of the innocent since rarely do guiltless persons voluntarily confess.”

As the Court said in Linkletter, 381 U.S. at 622, 85 S. Ct. at 1734, 33 B.W. at 4577 (footnote 5), “By final we mean where the judgment of conviction was rendered, the availablity of appeal exhausted, and the time for petition for certiorari had elapsed before our decision. . . .”
