concurring.
While I am in agreement with the result reached by the majority in the instant matter, the implications of the majority’s holding compel me to write separately.
*121I must accept the view of the majority in In re: Investigating Grand Jury of Philadelphia County (Appeal of Washington), 490 Pa. 31, 415 A.2d 17 (1980), that the exercise of judicial discretion with respect to the empanelment of an investigating grand jury is limited to a determination of whether the allegations of the district attorney in the application for empanelment are facially adequate in terms of the Investigating Grand Jury Act, 42 Pa.C.S. §§ 4541 et seq., and are made in good faith. It should be made clear, however, that neither that Act nor our case law supports the notion that an application for empanelment, once approved, is license to submit any investigation through a notice of submission. Subsequent submissions must be shown either to be within the original application for empanelment or meet the jurisdictional predicate for subject matter to be considered by a grand jury. The effect of a contrary interpretation would remove judicial supervision of the investigative process and gives to the district attorney virtual subpoena power. In order to justify the use of the grand jury’s resources in an investigation unrelated to the areas of need set forth in the application for empanelment, the supervising judge must hold the notice of submission to the same standards of facial adequacy and good faith as are imposed upon the initial application.
This requirement is fully supported by this Court’s decision in Appeal of Washington, supra:
[T]he empanelment and presentation of a matter for investigation to the grand jury are allowed to occur based on statements and allegations of the district attorney, and the function of the judiciary up to this point is limited to evaluating the facial adequacy under the Act of the application [for empanelment] and notice [of submission]. Id., 490 Pa. at 39, 415 A.2d at 21 (emphasis supplied).
We further recognized in that opinion that, although the statute does not require judicial approval prior to the submission of an investigation, a supervising judge has the power to reject sua sponte a facially inadequate notice. Id., 490 Pa. 39 at n. 9, 415 A.2d at 21 n. 9. In my judgment this *122power must be exercised, particularly where the subsequent submission pertains to matters beyond the original empanelment application. Such an action is consistent with the role of supervising judge and in no way contravenes the purposes of the Investigating Grand Jury Act.
Moreover, this procedure in no way impedes the investigative process, but rather provides a necessary safeguard against waste of the grand jury’s resources and needless inconvenience and expense to individuals subpoenaed. Meaningful judicial supervision of grand jury investigations thus dictates such an assessment.
The record demonstrates that the instant investigation was conducted in scrupulous compliance with the procedures prescribed in the Investigating Grand Jury Act and in Robert Hawthorne, Inc. v. County Investigating Grand Jury (Appeal of Thomas Hawthorne), 488 Pa. 373, 412 A.2d 556 (1980). The notice of submission described in detail the nature of the suspected criminal activity to be investigated as well as the scope of the proposed investigation. Further, that notice was in fact approved by the supervising judge. The Commonwealth furnished appellant with a Schofield affidavit and copies of both the application for empanelment and the notice of submission. In re Grand Jury Proceedings, 486 F.2d 85 (3d Cir.1973); Appeal of Hawthorne, supra. The supervising judge conducted an in camera hearing during which the Commonwealth disclosed its sources of information, the basis for its belief as to the existence of criminal activity and the reasons why the grand jury’s resources were required. Six of the seven documents submitted at the hearing in support of the Commonwealth’s averments were made available to appellant. Thus there is no basis for appellant’s claim that his motion to quash the subpoena was improperly denied.1
*123The majority opinion fails to discuss appellant’s argument relating to the President Judge’s failure to act upon the petition for empanelment within the ten (10) day requirement under 42 Pa.C.S. § 4543(b). The empanelment application was submitted to President Judge Bradley on or about July 1, 1982 and the order granting it was not signed by the President Judge until October 8, 1982, approximately three (3) months after he had received it. It is presently contended that the order of October 8, 1982 should be deemed null and void because of the noncompliance with § 4543(b).
In In re: County Investigating Grand Jury of April 24, 1981, Appeal of Krakower, 500 Pa. 557, 459 A.2d 304 (1983), this Court held that the use of an investigating grand jury is conditioned upon the present need for that body’s investigative resources. Moreover, section 4543(b) provides that the application for empanelment contain an averment that “[t]he convening of a county investigating grand jury is necessary because of the existence of criminal activity within the county which can best be fully investigated using the investigative resources of the grand jury.” Both the existence of criminal activity and the need for the grand jury’s investigative resources could conceivably evaporate during a three-month period. There may be a situation where a violation of section 4543(b) results in the empanelment of a jury at a time when either the existence of the criminal activity and/or the need for the use of the grand jury’s investigative resources were in fact no longer present.
I believe it is necessary to call attention to this argument because under certain factual situations a delayed signing of the application for empanelment may well justify a finding that the empanelment of the grand jury was improper. However, in the instant case I do not find any prejudice as a result of the delay inuring to the detriment of appellant. As indicated, the investigation of the matter in which appellant *124is concerned was not covered by the initial application for empanelment. The validity of the grand jury’s investigation into that area must depend upon the propriety of the subsequent notice of submission.
Accordingly, because the allegations in the notice of submission of the instant investigation satisfy the facial adequacy and good faith standards, I concur in the result.
. Appellant’s argument that the supervising judge’s refusal to conduct an evidentiary hearing as to the factual allegations in the notice of submission and the application to empanel precludes this Court from properly evaluating his challenge is of no moment. This is not the appropriate time for appellate review of such challenges. In the event of appellant’s subsequent prosecution and conviction, his claim *123is preserved for review. To permit appellate review at this stage of the proceedings would unnecessarily interrupt the progress of the investigation and erode its confidential character.
