The sole question in this appeal is whether the actions of a city are automatically outside the scope of the federal. antitrust laws. Answering in the negative, we reverse the decision below and remand for further proceedings.
I
A complaint filed on July 24, 1973, by the cities of Lafayette and Plaquemine, Louisiana (the Cities), alleged that appellant Louisiana Power & Light Company (Power
&
Light) and three other privately owned utilities had violated Sections 1 and 2 of the Sherman Act.
1
The allegations of this complaint are not involved in the present appeal. In its amended counterclaim, Power & Light charged the Cities with having themselves violated the federal antitrust laws in several respects. These allegations can be summarized as follows: (a) that the Cities were conducting sham litigation in order to delay or prevent Power
&
Light’s construction of a nuclear power plant; (b) that anticompetitive covenants were included in the Cities’ debentures;
2
(c) that the Cities had conspired with other parties to extend the provision of power to certain service areas beyond the time periods allowed by state law; (d) that the city of
*433
Plaquemine was requiring customers outside its city limits to purchase electricity from the city in order to obtain gas and water. All of these actions were alleged to violate Sections 1 and 2 of the Sherman Act. The “tie-in” of electricity to gas and water was alleged to violate Section 3 of the Clayton Act,

as well. In its order of February 28, 1975, the trial court dismissed the entire counterclaim. While noting its reluctance to exempt an enterprise which was “clearly a business activity” from the antitrust laws, the court held that the plaintiffs’ status as cities was sufficient to bring all their conduct within the “state action” exemption as announced in
Parker v. Brown,
II
In
Parker v. Brown,
The trial court in the present case acted without the benefit of the Supreme Court’s only major post-Parker explication of the “state action” doctrine. In
Goldfarb, supra,
the High Court was faced with a Sherman Act challenge to minimum fee schedules published by a county bar association and enforced by the Virginia State Bar. The state bar was a state agency by law,
id.
Taken together, these two controlling precedents require the following analysis. A subordinate state governmental body 6 is not ipso facto exempt from the operation of the antitrust laws. Rather, a district court must ask whether the state legislature contemplated a certain type of anticompetitive restraint. In our opinion, though, it is not necessary to point to an express statutory mandate for each act which is alleged to violate the antitrust laws. It will suffice if the challenged activity was clearly within the legislative intent. 7 Thus, a trial judge may ascertain, from the authority given a governmental entity to operate in a particular area, that the legislature contemplated the kind of action complained of. On the other hand, as in Goldfarb, the connection between a legislative grant of power and the subordinate entity’s asserted use of that power may be too tenuous to permit the conclusion that the entity’s intended scope of activity encompassed such conduct. Whether a governmental body’s actions are comprehended within the powers granted to it by the legislature is, of course, a determination which can be made only under the specific facts in each case. 8 A district judge’s inquiry on this point should be broad enough *435 to include all evidence which might show the scope of legislative intent. 9
Ill
The Cities argue that a decision adverse to them would necessarily overrule this Court’s prior opinion in
Saenz v. University Interscholastic League,
Even accepting
arguendo
the contention that
Saenz
automatically excludes subordinate state governmental bodies from the antitrust laws, we must still reject the notion that only an en banc Court could reach the result which we reach today. It is settled that the rule against inconsistent panel decisions has no application when intervening Supreme Court precedent dictates a departure from a prior panel’s holding. See
Davis v. Estelle,
5th Cir.,
*436 IV
To summarize, we conclude that the district court erred in holding the Cities’ actions to be automatically beyond the reach of the federal antitrust laws. Upon remand, the court must determine whether the activities alleged fall within the intended scope of the powers granted to the Cities by the legislature. In their briefs on appeal, the Cities have provided copies of statutes which allegedly comprehend the acts involved in Power & Light’s counterclaim. These are materials which should be submitted to the trial court in the first instance, together with all other relevant evidence.
REVERSED and REMANDED, with directions.

. Plaintiffs would have us equate cities and states for purposes of determining “state action”. No authority is cited for this proposition, and the only appellate decision directly on point has resolved this issue against plaintiffs. See
Duke & Co. v. Foerster,
. The opinion in
Goldfarb
does not support defendant’s claim that every alleged anticom-petitive activity must be specifically approved by the legislature. Thus, the
Goldfarb
Court would apparently have found an exemption if the Supreme Court of Virginia, acting within the intended scope of its legislative grant, had established minimum fees. See
. Our resolution of these general issues is in accord with that of the Third Circuit in
Duke & Co. v. Foerster, supra,
Brief mention should be made of plaintiffs’ argument that a decision such as this will lead to undesirable variations in the application of the antitrust laws, since the governmental activities subject to the
Parker-Goldfarb
exemption will differ from state to state. We regard this as an inevitable result of the emphasis in
Parker
and
Goldfarb
upon the scope of legislative intent. For instance, the
Goldfarb
Court made it clear that a statute specifically establishing minimum fee schedules would lead to a “state action” umbrella.
Plaintiffs also draw our attention to the dicta in
Goldfarb
which suggest that the Supreme Court of Virginia could, without new statutory authority, impose minimum fee schedules by means of court rules.
Id.
at 788-91,
As a final point, we cannot accept defendant’s invitation to import the discredited proprietary-governmental distinction into this area of the law. This contention is unsupported by authority and is irrelevant under Parker and Goldfarb, which look only to the scope of the legislative action and not the “proprietary” or “governmental” nature of the subordinate governmental body’s conduct.
. Therefore, we reject the capricious limitation suggested by counsel at oral argument, which would restrict a court’s inquiry to the pertinent statutes themselves.
. We are also unpersuaded by plaintiffs’ reliance upon
