Opinion of the Court
PER CURIAM.Appellant, Joseph D. McMahon, filed a writ of mandamus in the Commonwealth Court asserting that the Pennsylvania Probation and Parole Board had erred in computing his term of imprisonment upon his recommitment for a parole violation based upon subsequent criminal convictions. By memorandum opinion and order dated November 3, 1982, the Commonwealth Court dismissed the writ of mandamus and appellant filed a notice of direct appeal to this Court.
As explained in Pennsylvania Department of Aging v. Lindberg, 503 Pa. 423, 469 A.2d 1012 (1983) and its companion cases,1 the writ of mandamus in the instant case was not properly a matter addressed to the Commonwealth Court’s original jurisdiction, 42 Pa.C.S.A. § 761, but was, rather, a matter properly addressed to that court’s appellate jurisdiction, 42 Pa.C.S.A. § 763.
Accordingly, appeal to this Court is at our discretion, 42 Pa.C.S.A. § 724, not by right of appeal, 42 Pa.C.S.A. § 723(a). Pennsylvania Department of Aging v. Lind-*242berg, supra. We therefore deem the instant “direct appeal” as a petition for allowance of appeal, Pa.R.A.P. 1102, and deny the petition.
NIX, J., filed a dissenting opinion, in which McDERMOTT, J., joined.. XPress Truck Lines, Inc. v. Pennsylvania Liquor Control Board, 503 Pa. 399, 469 A.2d 1000 (1983); O’Brien v.
