OPINION OF THE COURT
This appeal arises from an order of the district court,
I.
Thomas Englert is the proprietor оf Northeast Electrical Inspection Agency (“Northeast Electrical”), engaged in the business of inspecting electrical work on public and privatе construction projects in western Pennsylvania. 1 Englert inspects the completed work to ensure compliance with the National Electrical Cоde and local building and electrical codes. Englert’s inspection fee is paid by the electrical contractor, but the ultimate cost is generally borne by the owner of the building as part of the total cost of the building or project.
Defendant Middle Department is a rival electrical inspection agency, also doing business in the western Pennsylvania area. On May 5, 1982, the City Council of McKeesport passed a resolution granting Middle Department the exсlusive right to perform electrical inspections within the city. As a result of this exclusive arrangement, Northeast Electrical is foreclosed from inspeсting electrical work in McKeesport.
Englert brought this action against Middle Department and McKeesport, alleging that their exclusive arrangement constituted a restraint of trade, monopolization, and attempted monopolization in violation of the Sherman Act, 15 U.S.C. §§ 1 & 2 (1982). Englert also brought a claim for violаtion of his rights under the fourteenth amendment, along with various pendent state claims. In this appeal we need only consider the Sherman Act claims. 2
Rather thаn answering Englert’s complaint, each defendant moved immediately for dismissal of the claims against it. Both alleged failure to state a claim upon which rеlief could be granted, Fed.R.Civ.P. 12(b)(6); Middle Department additionally challenged the district court’s jurisdiction over the subject matter of the claims, Fed.R.Civ.P. 12(b)(1), alleging an insufficient nexus with interstate commerce.
Englert amended his complaint in response to the jurisdictional challenge, incorporating a number of allegations designed to make out the requisite effect on interstate commerce. In particular, Englert alleged that much of the labor, material and other sеrvices involved in building construction in western Pennsylvania and McKeesport is supplied from out of state; that many of the electrical and general contractors and owners who paid the electrical inspection fees were from outside Pennsylvania; and that many of the projects inspected were financed with funds from the federal Department of Housing and Urban Development.
Defendants persisted in their motions to dismiss. On June 7,1983, the district court granted the motions and dismissed Englert’s suit for want of federal jurisdiction. Relying on the district court’s analysis in
Cardio-Medical Associates, Ltd. v. Crozer-Chester Medical Center,
II.
The district court in
Cardio-Medical
held that a mere “shifting” of interstate commerce from one entity to another, without a net change in the amount of commerce flowing across state lines, is not sufficient to engage the jurisdiction of the federal courts.
Since the date of the order and opinion below, this court has reversed the district court in
Cardio-Medical
and held that allegations оf “shifting,” standing alone, are in fact sufficient to satisfy the Sherman Act’s jurisdictional requirement.
It is clear to us, in light of Cardio-Medical’s reading of the “substantial and adverse effect” requirement, that the district сourt erred in dismissing Englert’s Sherman Act claims for want of subject matter jurisdiction. Taken as true, as they must be, Englert’s allegations are sufficient to withstand a Rule 12(b)(1) motion. Englert has alleged that the fee charged for electrical inspections is in many cases paid by out-of-state electrical and general contrаctors. 4
The payment of fees for professional services is certainly “commerce” within the meaning of the antitrust laws.
See Goldfarb v. Virginia State Bar,
Indeed, counsel for defendants conceded at oral argument that, in light of
Cardio-Medical,
Englert’s complaint is adequate to withstand challenge under Rule 12(b)(1). Noting, howеver, that an effect on interstate commerce is an element both of the jurisdictional standard and the substantive offense,
see Mortensen v. First Federal Savings & Loan Association,
We find no merit to this position. The Supreme Court in
Hospital Building Co. v. Trustees of Rex Hospital,
III.
Accordingly, we will rеverse the order of the district court dismissing Englert’s action for want of federal jurisdiction, and remand for proceedings consistent with this opinion.
Notes
. The facts we оutline here are drawn almost entirely from the allegations of Englert’s complaint. This appeal arises from a Rule 12(b) motion to dismiss. The defendants have not filed answers to Englert’s complaint, and have made no attempt to controvert Englert’s factual allegations. For purposes of this appeal, we must take these allegations to be true.
See Mortensen v. First Federal Savings & Loan Ass’n,
. The lower court’s dismissal of Englert’s federal constitutional claims has not been appealed to this court. Englert’s pendent state claims were dismissed along with the federal claims.
See United Mine Workers v. Gibbs,
. For an enlightening critique of the district court’s reasoning in Cardio-Medical, see Note, Sherman Act "Jurisdiction " in Hospital Staff Exclusion Cases, 132 U.Pa.L.Rev. 121 (1983).
. Englert has also alleged that many construction projects requiring electrical inspection are financed with federal funds, and that federal funds pay the inspection fee in these cases. These other allegations also would be sufficient to meet the jurisdictional requirement of §§ 1 and 2 of the Sherman Act.
