This case requires us to decide whether a statement obtained from an accused in violation of the six-hour rule of
Commonwealth v. Davenport,
On February 1,1979, at 9:45 p. m., defendant-appellee was arrested and taken to the West Detective Division of the Philadelphia Police Department. At about 10:45 p. m., the police obtained a signed, written statement from defendant. Defendant was arraigned at 3:47 the following morning, six hours and two minutes after his arrest. 1 He subsequently filed a motion to suppress his statement on the ground that it had been obtained in violation of Commonwealth v. Davenport, supra. The lower court denied the motion. After a *487 nonjury trial at which the Commonwealth did not introduce the statement and defendant did not testify, defendant was convicted of rape and simple assault. In post-verdict motions, defendant again challenged the admissibility of his statement. The lower court concluded that it had erred in denying defendant’s suppression motion because the statement has been obtained in violation of the Davenport rule. Additionally, the court concluded that statements inadmissible under Davenport should not be used to impeach an accused’s trial testimony. Although defendant herein did not testify at trial, the court accepted his argument that he had been prejudiced by its refusal to suppress his statement because his decision not to testify had been based on his fear that the Commonwealth would use the statement to impeach his credibility. The court therefore granted defendant’s motion for a new trial. The Commonwealth then took this appeal.
“The Pennsylvania Rules of Criminal Procedure require that an individual who is arrested be brought before a judicial officer for preliminary arraignment without unnecessary delay. Pa.R.Crim.P. 122, 130.”
Commonwealth v. Davenport,
The lower court concluded that defendant’s statement should have been suppressed because his preliminary arraignment was not held “within six hours of arrest ... . ” *488 Id. The Commonwealth argues, however, that the Davenport rule should not be “mechanically” applied here because defendant’s arraignment was held only two minutes after the expiration of the six-hour period and was caused by “a trivial administrative oversight.” Brief for the Commonwealth at 10. As the lower court recognized, however, the Davenport rule would have to be rewritten to uphold the Commonwealth’s argument. That we refuse to do. Moreover, were we to find no violation of the Davenport rule in this case, we would open the door to a host of claims involving assertedly de minimis Davenport violations and be forced to engage in precisely the sort of case-by-case determinations which our Supreme Court sought to avoid by adopting an unambiguous rule. 2 Accordingly, we agree with the lower court that defendant’s statement was obtained in violation of the Davenport rule. We shall now determine whether a statement inadmissible under Davenport may be used to impeach the accused’s trial testimony.
In
Harris v. New York,
The impeachment process here undoubtedly provided valuable aid to the jury in assessing [defendant’s] credibility, and the benefits of this process should not be lost, in our *489 view, because of the speculative possibility that impermissible police conduct will be encouraged thereby. Assuming that the exclusionary rule has a deterrent effect on proscribed police conduct, sufficient deterrence flows when the evidence in question is made available to the prosecution in its case in chief.
Every criminal defendant is privileged to testify in his own defense, or to refuse to do so. But that privilege cannot be construed to include the right to commit perjury... . Having voluntarily taken the stand, [defendant] was under an obligation to speak truthfully and accurately, and the prosecution here did no more than utilize the traditional truth-testing devices of the adversary process.
In
Commonwealth v. Triplett,
Harris-type use of constitutionally infirm confessions forces upon an accused a grisly Hobson’s choice. Either an accused must forgo his right to testify, or he must risk the sure and devastating prejudice occasioned by the prosecution’s use of the impermissibly obtained confession at the critical rebuttal stage.
*490
Although the Court’s broad language in
Triplett
could be construed as applying not only to constitutionally infirm statements but also to statements obtained in violation of a rule which is not constitutionally mandated, such as
Davenport,
the Court subsequently clearly indicated that it had not intended such a result. In
Commonwealth v. Sparrow,
We have never had occasion to consider whether the exclusionary rule of Futch, established pursuant to our supervisory authority and designed to discourage excessive detention in police custody of persons under suspicion of crime before bringing formal charges, should extend to the use of confessions for impeachment purposes. The exclusion involved in Commonwealth v. Triplett, ... of course, was based on the constitutional infirmity of the statement there sought to be used for impeachment.
The
Davenport
rule, like the
Futch
rule, was based on our Supreme Court’s supervisory authority, rather than either the Federal or Pennsylvania Constitution.
Davenport,
Although we have determined that defendant’s statement was obtained in violation of Davenport, defendant was not prejudiced by the lower court’s initial error in refusing to suppress it because the Commonwealth did not refer to it at trial. Moreover, because the statement could have been used to impeach defendant’s credibility, defendant’s claim that he chose not to testify because he believed that the Commonwealth would use his statement does not entitle him to a new trial. Accordingly, we reverse the lower court’s order granting defendant a new trial.
Order reversed and case remanded for consideration of defendant’s other post-verdict motions.
Notes
. The record is silent as to the precise reason for the delay in arraigning defendant. The record reveals only that a police officer ignored instructions to have defendant arraigned within six hours of his arrest.
. Although this Court has held that the
Davenport
per se rule applies “ ‘in the absence of exigent circumstances,’ ”
Commonwealth v. Ryles,
. Of course, a statement obtained in violation of the Davenport rule cannot be used for impeachment purposes if it is shown to be coerced or involuntary. See New Jersey v. Portash, supra (coerced or involuntary statement cannot be used for impeachment under Harris). In the instant case, defendant has not alleged that his statement was coerced or involuntary, and the record does not support such a claim.
