Opinion by
Me. Justice Eagen,This is an appeal from an order below dismissing an action in habeas corpus without hearing.
The appellant, Frank Smith, is confined under a sentence of life imprisonment imposed on June 28, 1950, following his conviction by a jury of murder in the first degree. Throughout the trial proceedings, he was represented by self-retained counsel. A motion for a new trial was filed and later withdrawn. No appeal from the judgment was entered.
In the present action, Smith contends, that the trial resulting in his conviction and sentence lacked due process because it was basically unfair and fraught with multiple trial errors. He complains: (1) that the trial court permitted in evidence at trial police witness testimony, that during questioning Smith was confronted by alleged accomplices1 who made recorded statements in his presence that they, together with Smith, committed the robbery2 and that Smith failed to deny their statements; (2) that the trial judge erred in his instructions to the jury concerning the impact of Smith’s failure to enter a denial on the occasion described; (3) that the trial judge erroneously prejudiced Smith’s trial by permitting his accomplices (Young and Collins) to be present in court and to be identified without being called as witnesses; (4) that the trial court erred in permitting to be read at trial the recorded statements of Young and Collins made in the pres*96ence of Smith which involved him in the crime; (5) that the trial judge erroneously permitted the prosecution to plead surprise during the testimony of a witness and to then cross-examine this witness; (6) that the trial judge erred in instructing the jury that a not guilty verdict “would be a miscarriage of justice”; and (7) that Smith was held incommunicado for eleven days by the police before being given a preliminary hearing.
It is readily apparent that Smith’s complaints, in large part, involve questions that should have been raised by direct appeal and are not a proper basis for the issuance of habeas corpus. See, Commonwealth ex rel. Robinson v. Myers, 420 Pa. 72, 215 A. 2d 637 (1966), and Commonwealth ex rel. Rivers v. Myers, 414 Pa. 439, 200 A. 2d 303, cert. denied, 379 U. S. 866 (1964). However, if the trial were basically unfair and thus violated the constitutional requirements of due process, or if any part of the proceedings involved constitutional errors, the remedy of habeas corpus is properly employed. See, Commonwealth ex rel. Robinson v. Myers, supra, and Commonwealth ex rel. Butler v. Rundle, 407 Pa. 535, 180 A. 2d 923 (1962). Therefore, we have carefully examined the record in depth. We find no valid reason why the writ should issue. We will, therefore, affirm.
The Commonwealth’s trial testimony established that three men committed an armed robbery of a taproom in the city of Philadelphia, and during its occurrence a patron, one William Hill, was beaten over the head with a revolver causing injury resulting in death. Testimony of two eyewitnesses unequivocally identified Smith as one of the felons. Further, Smith testified at trial and admitted participation in the robbery, but denied having a revolver or assaulting the deceased victim. The defense also argued, although the Commonwealth’s evidence as to the cause of death was uncon*97tradicted, that the death was due to natural causes and not an assault.
In view of this record, particularly Smith’s own trial testimony, we find no merit in the argument that the trial judge’s comment, that a not guilty verdict would be a miscarriage of justice, was unwarranted or unfair. This is especially so, since it also appears that the jury received careful instructions that the determination of all factual questions was solely for its decision, and that a not guilty verdict could be returned.
As to the alleged trial error of admitting testimony that Smith failed to deny the incriminating statements of his accomplice and thus made a tacit admission of the truth of the accusations, Commonwealth ex rel. Shadd v. Myers, 423 Pa. 82, 223 A. 2d 296 (1966) is generally controlling. However, there is an added circumstance in connection therewith that indicates discussion.
According to the trial testimony Smith, Young and Collins were first questioned about the crime on the night immediately following its occurrence. During this period Young, in the presence of Smith and Collins, orally stated that the three had joined in committing the robbery and that Smith had hit the victim, Hill. At this time Smith, “tightened his lips,” “lowered his head and shook his head from side to side.” Smith was then asked if he wished to ask Young any questions. He remained silent. Shortly thereafter, again with all three present, Collins orally stated that what Young said about the commission of the robbery was true, but that he did not see or know if Smith hit Hill. Following this Smith remained silent and did not indicate in any manner that the statement was untrue. The following morning Smith, Young and Collins were again questioned in the presence of each other. Warnings were given that anything they said would be taken down and used against them in court. *98Young was specifically told that he was entitled to be represented by counsel during the questioning. He declined such assistance. The questions and answers were typewriter recorded. Therein Young and Collins essentially repeated what they had said the night before. Smith was asked if he heard the accusations. He answered “Yes”, but refrained from further comment.
This testimony was admitted under the rule of evidence heretofore long followed in Pennsylvania, that Smith’s behavior and silence under the circumstances could be construed by the jury as an admission or tacit acquiescence in the truth of the incriminating statements of his accomplices. See, Commonwealth ex rel. Shadd v. Myers, supra.3 In charging the jury the trial judge said that his impression of the desci’iption given as to how Smith tightened his lips and shook his head (when first confronted with Young’s admissions and accusations) was one of consternation or surprise that his buddies had told on him. However, he immediately added that his impression was not binding on the jury and that if they concluded “that Smith said no, then you cannot consider that testimony, because Smith then made a denial. Where a man makes a denial, then any statement made against him in his presence cannot be considered.” We fail to see merit in the argument that this instruction was unfair or violated the constitutional requirements of due process.
Finally, as noted before, Smith complains that he was held incommunicado by the police and not given a preliminary hearing for eleven days. This, of course, is not condoned and is not now permitted under our new Eules of Criminal Procedure. However, the absence of an immediate preliminary hearing does not, *99per se, constitute a violation of constitutional rights. See, Commonwealth ex rel. Fox v. Maroney, 417 Pa. 308, 207 A. 2d 810 (1965), and Commonwealth ex rel. Shaffer v. Cavell, 419 Pa. 218, 213 A. 2d 380 (1965). Here in, aside from the evidence of tacit admissions made within a period of thirty-six hours following his arrest, and to which no allegation of coercion was suggested at trial, nothing prejudicial occurred at trial resulting from Smith’s confinement.
Order affirmed.
Mr. Justice Cohen concurs in the result.These individuals, Jesse Young and John E. Collins, later entered a general plea of guilty to the charge of murder, and after hearing were adjudged guilty of murder in the first degree and sentenced to life imprisonment.
A fatal beating occurred during this robbery.
See, however, Miranda v. Arizona, 384 U. S. 436, 468, footnote 37, and Johnson v. New Jersey, 384 U. S. 719, 733, stating that Miranda is not to be applied retroactively.
