Appellee, Michael Xavier Pfender, is charged with arson and related offenses 1 in Lancaster County. Pfender’s former attorney met with the District Attorney to discuss the charges and thereafter an agreement was reached whereby Pfender would voluntarily undergo a polygraph (lie detector) test. The proposed use of the polygraph test results was set forth in a stipulation signed by Ronald L. Buckwalter, District Attorney of Lancaster County, Samuel M. Me-cum, Pfender’s attorney and appellee. The stipulation provides:
AND NOW, this 30 day of October, 1978, Michael Xavier Pfender, Defendant in the above-captioned matter, and Ronald L. Buckwalter, Esquire, District Attorney of Lancaster County, hereby stipulate and agree as follows:
1. Defendant Michael Xavier Pfender agrees to submit himself to a Polygraph (lie detector) test, which test will be designed to determine whether or not Defendant Pfender is telling the truth, in connection with his recollection of events transpiring at the Willow Street Mobile Home Park, 1014 Willow Street Pike, Lancaster, Pennsylvania, on or about the date of April 16, 1978.
2. The Polygraph, or lie detector test is to be administered by any qualified member of the Lancaster City Police Department.
*420 3. It is agreed on part of Defendant Pfender that, should the results of the Polygraph indicate deception, these results may be used against him in connection with information No. 1376 of 1978.
4. On part of Ronald L. Buckwalter, Esquire, District Attorney of Lancaster County, it is agreed that, should the results of the Polygraph test indicate no deception on the part of Defendant Pfender, information No. 1376 of 1978 shall be nol prossed (dismissed).
5. Defendant Michael Xavier Pfender expressly certifies that this Stipulation is entered voluntarily on his part, after having had his legal rights explained to him by his attorney, Samuel M. Mecum, Esquire, of 121 East King Street, Lancaster, Pennsylvania, and further certifies that he has been made aware of the fact that he is not required to enter into the above Stipulation, and does so, * * * any rule of law or of court to the contrary notwithstanding.
STIPULATED AND AGREED the day and year first above written.

Pursuant thereto, a polygraph test was administered to appellee by an experienced polygraphist from the Lancaster Bureau of Police, Jan G. Walters. The result in the opinion of Mr. Walters, was that Pfender was “hot being entirely truthful” in that the examiner found deception indicated in three of the four pertinent questions asked during the test.
*421 Thereafter, Pfender obtained new counsel who filed an application to suppress any evidence of the results of the polygraph examination. After a hearing the Court suppressed the results of the polygraph examination, reasoning that since the appellate courts in Pennsylvania have determined that the results of polygraph tests are inadmissible in evidence, that a stipulation could not cure the inadmissibility. The court found, however, that the stipulation was entered into by Pfender “knowingly, voluntarily and intelligently, without coercion having been exerted against him.” The court also entered a certification under the Act of July 9, 1976, P.L. 586, No. 142 § 2 (42 Pa.C.S. § 702(b)) that an immediate appeal may materially advance the ultimate termination of the case. However, since the Commonwealth did not file a petition for permission to appeal as required by Pa.R.A.P. 1311, the certification under § 702(b) does not provide us with jurisdiction over this case.
Nevertheless it is settled that the Commonwealth may appeal from a pretrial suppression order if the question raised is a pure question of law and if the order effectively terminates or substantially handicaps the prosecution.
E.g., Commonwealth v. Saunders,
I
We are thus asked to determine the admissibility of poly-graphic evidence by stipulation of the parties. Before attempting to decide this issue, we first consider the status of Pennsylvania law on the subject of polygraph evidence in general. Pennsylvania cases still adhere to the principle set forth in
Commonwealth ex rel. Riccio v. Dilworth,
The reliability and scientific infallibility of polygraph, lie detector, or other psychological deception test must be more definitely established before our courts will accept their results as credible.”179 Pa.Super. at 68 ,115 A.2d at 867 .
In 1976 the Supreme Court of our State reiterated the exclusionary rule of
Riccio
noting that it has been repeatedly and consistently held in Pennsylvania that the results of a polygraph examination are inadmissible for “any purpose” because the reliability of such tests has not been established.
Commonwealth v. Gee,
Certainly it is incumbent upon us to be alert to developments in this field so that, if indeed lie detectors have passed beyond the experimental stage to a trustworthiness comparable to that of other scientific tests whose results have immeasurably aided our courts in their search for truth, we do not deny ourselves the enlightenment they might provide. (467 Pa. at 142 ,354 A.2d 875 .)
*423
The court in
Gee
nevertheless declined to reconsider the established view of inadmissibility since in that case the polygraph test results were inconclusive. Since the time of
Gee,
our appellate courts have not reexamined the rule of inadmissibility and still follow the principle that polygraphic examinations have not obtained acceptance as a reliable means of ascertaining truth or deception.
See Commonwealth v. Kemp,
Thus, it is the present view in Pennsylvania that such test results are not reliable even though the courts have evinced a desire to keep an open mind on the subject.
On the precise issue of admissibility of polygraphic evidence pursuant to stipulation we find that the Pennsylvania cases have only incidentally touched upon the subject. In
Commonwealth v. McKinley,
In the absence of a stipulation of the parties to the contrary, the results of lie detector tests are inadmissible when offered in evidence for the purpose of establishing the guilt or innocence of one accused of a crime, whether the accused or the prosecution seeks its introduction. (181 Pa.Super. at 619 ,123 A.2d 735 .)
We do not deem this statement as being any authority for the admission of polygraphic evidence by stipulation. The court was simply supporting its conclusion that the results of such tests are inadmissible and that therefore any evidence of an offer to undergo the test would likewise be inadmissible.
In
Commonwealth v. Chapman,
It appears then, that the question of admissibility of polygraphic evidence by stipulation has yet to be squarely met in Pennsylvania.
II
The leading case dealing with the admissibility of poly-graphic evidence by stipulation is
State v. Valdez,
Although much remains to be done to perfect the lie detector as a means of determining credibility we think it has' been developed to a state in which its results are probative enough to warrant admissibility on stipulation. (91 Ariz. at 283 ,371 A.2d 894 .)
The court held that polygraph evidence is admissible after stipulation to corroborate other evidence of a defendant’s participation in the crime charged and to corroborate or impeach his own testimony if the defendant takes the stand. The court also laid down qualifications which must be met in order to permit the use of the evidence. 3
*425
Ten years later the Supreme Court of New Jersey in
State
v.
McDavitt,
More recently the question of admissibility of polygraphic evidence by stipulation limited to the issue of the defendant’s credibility was faced by the highest court in West Virginia in
State v. Frazier,
W.Va.,
*426
Similarly, the Supreme Court of Alaska in
Pulakis v. State,
A stipulation for admission does not increase the reliability of polygraph results and therefore should not lead to any deviation from the exclusionary policy. (476 P.2d at 479 .)
In Oklahoma the Court of Criminal Appeals in 1975 re-, versed a line of cases admitting polygraph evidence upon stipulation and found that the potential unreliability of polygraphy dictated its total exclusion.
In the situation where all parties in the case stipulate to the admission of results of a polygraph examination, this Court has held that it is within the discretion of the trial court to admit such evidence. See, Castleberry v. State, Okl.Cr.,522 P.2d 257 (1974) and Jones v. State, Okl.Cr.,527 P.2d 169 (1974). However, in light of the potential unreliability of polygraph examinations at this time, we feel that in all future cases the introduction into evidence of polygraph examination results for any purpose, even if admitted upon stipulation of all parties, will be error.
Fulton
v.
Oklahoma,
Okl.Cr.,
We think these last cases illustrate the proper view for Pennsylvania Courts on this issue.

As previously noted, our cases have held that the reliability of polygraphic test results have not as yet been sufficiently demonstrated. No Pennsylvania case has undertaken a review of the science of polygraphy in order to evaluate its present reliability. Our research discloses that there is no jurisdiction where the test is held to be generally admissible at trial. This has been the result even after an exhaustive analysis of the legal and scientific value of polygraphic evidence. See
State v. Catanese,
Since the general admissibility of polygraphic test evidence has not been argued here and the record is devoid of any evidence as to the reliability of polygraph test results, we do not deem it appropriate for us to consider the broad issue in this case.
We conclude that evidence of results of the poly-graphic tests is not admissible in evidence even in the face of a knowing, voluntary and intelligent stipulation that they may be submitted in evidence.
Order affirmed.

State v. Valdez, supra,
(1) That the county attorney, defendant and his counsel all sign a written stipulation providing for defendant’s submission to the test and for the subsequent admission at trial of the graphs and the examiner’s opinion thereon on behalf of either defendant or the state.
(2) That notwithstanding the stipulation the admissibility of the test results is subject to the discretion of the trial judge, i.e. if the trial judge is not convinced that the examiner is qualified or that the test was conducted under proper conditions he may refuse to accept such evidence.
(3) That if the graphs and examiner’s opinion are offered in evidence the opposing party shall have the right to cross-examine the examiner respecting:
a. the examiner’s qualifications and training:
*425 b. the conditions under which the test was administered;
c. the limitations of and possibilities for error in the technique of polygraphic interrogation; and
d. at the discretion of the trial judge, any other matter deemed pertinent to the inquiry.
(4) That if such evidence is admitted the trial judge should instruct the jury that the examiner’s testimony does not tend to prove or disprove any element of the crime with which a defendant is charged but at most tends only to indicate that at the time of the examination defendant was not telling the truth. Further, the jury members should be instructed that it is for them to determine what corroborative weight and effect such testimony should be given.

also: State
v.
Christopher,
. For a collection of cases on admissibility by stipulation see
. Catanese points out that caution is dictated in the area of admission of polygraph results in that the questions which deal with the *427 very basic issues in a case are likely to be given great weight by the fact finder. The court felt that before consideration could be given to admitting polygraphic evidence there should be state regulation and licensing of polygraphers (Pennsylvania has none) and that procedural safeguards should be established by court rule or legislation.
