This petition seeking a writ of prohibition was filed in this Court following the denial of a motion to quash a subpoena by the Court of Common Pleas of Philadelphia. The subpoena ordered petitioner, inter alia, to appear before an investigatory grand jury in Philadelphia. The grand jury was
convened pursuant to the Investigating Grand Jury Act, Act of November 22, 1978, P.L. 1148, No. 271, §§ 1 et seq., 19 P.S. §§ 265 et seq., following the approval by the Court of Common Pleas of an application made by the district attorney.
In re: Petition of Specter, 455 Pa. 518, 317 A.2d 286 (1974), is controlling. There we said:

Forcing the party subpoenaed to make such a choice is justified by the 'necessity for expedition in the administration of the criminal law.' United States v. Ryan, supra, 402 U.S. at 533, 91 S.Ct.  at 1582. What the petitioner is not permitted to do by direct appeal, she is apparently attempting to do by a writ of prohibition.
The principles regulating the issuance of writs of prohibition were clearly set forth in Carpentertown Coal & Coke Co. v. Laird, 360 Pa. 94, 61 A.2d 426 (1948), where we said, at page 102, 61 A.2d 426: 'The writ of prohibition is one which, like all other prerogative writs, is to be used only with great caution and forbearance and as an extraordinary remedy in cases of extreme necessity, to secure order and regularity in judicial proceedings if none of the ordinary remedies provided by law is applicable or adequate to afford relief. It is a writ which is not of absolute right but rests largely in the sound discretion of the court. It will never be granted where there is a complete and effective remedy by appeal, certiorari, writ of ...
