delivered the opinion of the Court.
This suit was brought in a federal court for Louisiana by Herkness, an owner of natural gas wells, to enjoin the *93 Commissioner of Conservation and the Attorney General of that State from interfering with the erection, on plaintiff’s land, and the operation, of a factory for the manufacture of carbon black from natural gas. The bill alleges that a number of оther persons are now engaged in that business and have been for many years with the sanction of the Department of Conservation; that it had been its practice to require persons about to engage , in such manufacturе to apply for a permit; that one of its rules declares unlawful the erection of such a factory without hаving first obtained one; that plaintiff was refused a permit; that the sole ground of refusal was the policy recently announced by the Commissioner not to issue a permit for the erection of any new carbon black plants and to gradually reduce'the amount of gas which holders of permits to operate existing plants can utilize for that purpose; and that his policy has become a fixed rule of administration. The bill charges that the order refusing to issue a permit to the plaintiff is void, because in excess of the powers conferred by the statutes or which cоuld be conferred under the constitution of the State; and also because it violates the due process clause ,and the equal protection clause of the Fourteenth Amendment.' A restraining order and an interlocutory injunction, as well as a permanent injunction, were sought. There were adequate allegations of threatened irreparable injury.
The District Judge issued a restraining order. The hearing upon the application for an interlocutory injunction was had before three judges, under § 266 of the Judicial Code as amended; and the case was latеr submitted by agreement as upon final hearing. The court.denied the injunction and dismissed the bill, 11 F. (2d) 386; but later granted a restraining ordеr pending the appeal. As the bill challenged the validity under the Federal Constitution of an order of an administrative board of the State,
*94
the District Court had jurisdiction under § 266,
Oklahoma Gas Co.
v.
Russell,
The conservation of natural resources has been the subject of muсh legislation in Louisiana.
1
The possible wastefulness of the use of natural gas in the manufacture of carbon blaсk was recognized; and the Legislature dealt fully with this .use by Act 252 of 1924, which, in effect, embodies the provisions of Act 91 of 1922.
State
v.
Thrift Oil & Gas Co.,
Many detailed provisions concerning permits for thе building of plants to burn natural gas into carbon black were added by Act 252 of 1924. But the additional provisions, and the speсific powers there conferred upon the Commissioner, deal only with regulation of the use. The legislation contemplates, not restriction of the use to existing plants, but the further issue of permits to all who will “ completely abidе by and comply with all the provisions of this Act, and with all the rules and regulations of the Commissioner of Conservation estаblished under the provisions of the Act.” § 5. And it expressly provides that “ The authority given the Commissioner of Conservation by this Act shаll in no sense be understood to supersede or nullify any of the provisions of this Act, or any other act of this State, but shall be cumulative and in aid thereof.” § 11.
As it is clear that the refusal of the Commissioner was not justified by any statutory provision, wе have no occasion to consider the limitations imposed by the constitu *96 tion of the State upon discriminatory action 2 and upon delegation of legislative power to an executive department. 3
Reversed.
