Opinion by
President Judge Bowman,The issue raised by a motion to quash the instant appeal, though narrow, is one of first impression and *446affects virtually every appeal to this Court from an adjudication of a state administrative agency pursuant to Section 403 of the Appellate Court Jurisdiction Act of 1970 (ACJA), Act of July 31, 1970, P. L. 673, as amended, 17 P.S. §211.403, which confers jurisdiction in this Court over such appeals.
Section 502, ACJA, 17 P.S. §211.502, dealing generally with the time for appeal, provides, with two exceptions not here relevant, that an appeal under the Act from any order shall be filed “within thirty days of its entry ”
A host of statutes, including the Public Utility Law, Act of May 28, 1937, P. L. 1053, as amended, 66 P.S. §1101 et seq., here involved, speaking on the subject of judicial review of state administrative adjudications, contain provisions inconsistent with Section 502, ACJA, as to the event from which the time limitation for appeal is measured. Section 1101 of the Public Utility Law, 66 P.S. §1431, requires such appeals to be taken within thirty days “after the service of any order by the commission,” thus clearly in conflict with Section 502, ACJA. A multitude of other statutes governing particular state administrative agencies variously prescribe the event from which the time limitation for appeal is to be computed as “service of notice” of the order, “mailing of decision” and similar phrases, all equally clear as being inconsistent with Section 502, ACJA.
Given inconsistent provisions as to the event from which the time limitation for an appeal is to be measured, which provision shall prevail — Section 502, ACJA, enacted subsequent to Section 1101 of the Public Utility Law, or Section 1101?
There is no factual dispute in the instant case that the appeal was timely taken if measured from the date of service of the order of the Commission on appel*447lants, and untimely taken if measured from the entry of the order.
Appellants, in strenuously opposing the motion to quash filed by the intervening appellee in this appeal, correctly point out that Section 1101 of the Public Utility Law was not specifically repealed by the provisions of the AOJA. Absent a specific repeal, appellants argue that the legislature intended the preservation of the provisions of Section 1101 relating to the event from which the time for appeal is to be measured, this legislative intent being demonstrated by its specific action in providing that the Commonwealth Court, not the Superior Court, should have jurisdiction of appeals as disclosed by the amendatory Act of June 3, 1971, P. L. 118, which extensively amended the ACJA and has been commonly referred to as a housekeeping act.
As pertinent here, the Act of June 3,1971, P. L. 118, amended subsection (a) of Section 509, ACJA, 17 P.S. §211.509, — the absolute repealer section of the ACJA— by adding a new clause which, in pertinent part, reads: “(115) ... as much of the first sentence as reads as follows: ‘to the Superior Court’ and the second and last sentences of subsection (a) and as much of the first sentence as reads as follows: ‘to the Superior Court’ of subsection (b) of section 1101 . . . act of May 28, 1937 (P. L. 1053), known as the ‘Public Utility Law.’ ”
Contrary to appellants’ contention, we can find no legislative intent from this enactment that the provisions of Section 1101 of the Public Utility Law as to the event from which the time for appeal is to be measured are preserved either on the theory that it constitutes a reenactment of Section 1101 or an amendment to the entire Section 1101 subsequent to the conflicting provisions of Section 502, ACJA. As it clearly provides, it repeals inconsistent provisions of the Public Utility Law with provisions of the ACJA as to which *448court — the Superior Court or the Commonwealth Court —enjoys jurisdiction over appeals from commission orders. It is only to that subject the above provisions of the Act of June 3, 1971, P. L. 118, speak.
Rather, the issue in question must be resolved by consideration of other provisions of the ACJA from which we must conclude that the provisions of Section 1101 of the Pubilc Utility Law relating to the event from which the time for appeal is to be computed or measured, being in conflict with Section 502, ACJA, have been repealed. In our opinion, this conclusion is inescapable; by application of fundamental principles of statutory construction, Section 509 of the ACJA as originally enacted, after repealing absolutely enumerated sections of particular statutes (vastly expanded in the so-called housekeeping Act of June 3, 1971, P. L. 118), contains in subsection (f) a general repealer which provides that “all other acts and parts of acts are hereby repealed in so far as inconsistent with this act.” It is well settled that these are words of express repeal of all previous inconsistent legislation. See Commonwealth ex rel. A. C. Braughler v. John Weir, 165 Pa. 284, 30 A. 835 (1895) and Bourguignon Building Association v. Commonwealth, 98 Pa. 54, 1 Penny. 193 (1881).
That the two statutory provisions in issue as to the event from which the time for appeal is to be measured are conflicting cannot be gainsaid. That the general repealer contained in Section 509(f) of the ACJA controls the result we have reached is well settled. Newbold v. Pennock, 154 Pa. 591, 26 A. 606 (1893); Commonwealth ex rel., Appellant v. Keeper of County Prison, 49 Pa. Superior Ct. 647 (1912).
Although not on point as to the issue here raised, other issues involving interpretation of the provisions of the ACJA in conflict with other statutory law either predating or postdating enactment of the ACJA have *449had our attention. See Pottsgrove School District v. Pennsylvania Labor Relations Board, No. 10 Transfer Docket 1972, decided March 10, 1972, Pa. Commonwealth Ct., aff’d, 451 Pa. 404, 304 A. 2d 491 (1973), (regarding which tribunals in Pennsylvania enjoy jurisdiction to entertain appeals from decisions of the Pennsylvania Labor Relations Board regarding municipal and county employees under the Public Employe Relations Act, Act of July 23, 1970, P. L. 563, §1502, as amended, 43 P.S. §1101.1502); see also Hartman v. Commonwealth, 6 Pa. Commonwealth Ct. 409, 295 A. 2d 850 (1972), (regarding which tribunals in Pennsylvania enjoy jurisdiction to entertain appeals de novo from decisions of the Department of Transportation regarding suspension of motor vehicle inspection station licenses). However, cf. Pittsburgh v. P.U. C. and Duquesne Light Company, 3 Pa. Commonwealth Ct. 546, 284 A. 2d 808 (1971), (holding that other statutory procedures incident to appeal set forth in Article XI of the Public Utility Law, Act of May 28, 1937, P. L. 1053, as amended, 66 P.S. §1101 et seq., are not repealed by enactment of the AOJA).
We reach this conclusion reluctantly not because of doubt as to the conclusion here reached but because it ousts our jurisdiction to hear this appeal on its merits. Luckenbach v. Luckenbach, 443 Pa. 417, 281 A. 2d 169 (1971).
Finally, we note a number of legislative enactments adopted subsequent to the adoption of the AOJA and subsequent amendments and reenactments of statutes predating the ACJA. Thus, decision in this case should not be assumed as controlling similar issues involving different statutory histories. Certainty does not exist in this field and until it does the practitioner should proceed with careful determinations of the procedure to be employed in timely taking and perfecting such an appeal.
