Most of the questions presented by this case are the same as those that were raised in Watson v. Buck, 313 U.S. 387, 61 S.Ct. 962, 85 L.Ed. —-, this day decided. Here, as there, at the request of ASCAP and its co-complainants a federal District Court composed of three judges enjoined various state officials from enforcing a state statute1 aimed primarily at price-fixing combinations operating in the field of public performance of copyright music.2 Here, as there, the complainants alleged, and the defendants denied, that enforcement of the act had been threatened. Here, as there, the court below found that threats had been made, that some of the sections of the act were invalid, that the invalidity of those sections permeated the whole, and that the state officials should be enjoined from enforcing any of the numerous provisions of the Act. But, as in the Florida case, the court below proceeded on a mistaken premise as to the role a federal equity court should play in enjoining state criminal statutes. Here, there was no more of a showing of exceptional circumstances, specific threats, and irreparable injury than in the Florida case. In his brief in this Court, the Attorney General of Nebraska stated that 'Appellants, as law enforcement officers, sincerely hope that no action under this law will be required. None was threatened before nor since the suit was started.' With one possible exception, the record bears out the statement of the Attorney General; there was no evidence whatever that any threats had been made, but in his answer the Attorney General stated that he would 'enforce the act against the complainant Society * * * (if) the complainant Society would operate in the State of Nebraska in violation of the terms of the statute by conniving and conspiring to fix and determine prices for public performance of copyrighted musical compositions * * *.' As we have just held in Watson v. Buck, it was error to issue an injunction under these circumstances.

In other material respects also, this case is like the Florida case. The court below failed to pass on what we consider the heart of the statute because of what it regarded as the pervading vice of the invalid sections. But section 12 of the Nebraska statute is similar to section 12 of the Florida statute and provides that 'If any Section, subdivision, sentence or clause in this Act shall, for any reason, be held void or non-enforceable, such decision shall in no way affect the validity or enforceability of any other part or parts of this Act.' The legislative will is respected by the Supreme Court of Nebraska,3 and the court below should have followed state law in this regard. That part of the statute on which the court did not pass—and the part which the Attorney General said he stood willing to enforce if violated—set up a complete scheme for the regulation of combinations controlling performing rights in copyright music. On the authority of Watson v. Buck, the decision below is reversed and the cause is remanded with instructions to dismiss the bill.

Reversed and remanded with instructions.

It is so ordered.
