OPINION
Before MERRILL and KOELSCH, Circuit Judges, and SWEIGERT, * District Judge.
This is another permutation in the complicated maze created by the Supreme Court’s reformulation of the boundary line between protected speech and unprotected obscenity in Miller v. California,
Appellant John Andrew Jacobs was indicted, tried, and convicted for violation of 18 U.S.C. § 1462 (knowingly receiving an obscene film transported in interstate commerce) after June 23, 1973, the date on which the Supreme Coui’t rendered the decision in Miller. The date of the alleged offense, however, was May 10, 1973, before Miller was decided. The jury which convicted appellant was instructed using the definition of “obscenity” enunciated in Miller, rather than the Roth-Memoirs 1 definition which preceded it. Appellant argues that the Miller definition expanded the area of unprotected speech which is now made subject to criminal sanction under § 1462, and that retroactive application of such expanded standards to his conduct was effectively the application of ex post facto law, violating his due process right to notice of the conduct proscribed. As we agree that the Roth-Memoirs gloss on “obscenity” did not give appellant adequate notice that his conduct would be judged by the expanded standard ultimately applied, we reverse his conviction.
Before Miller was decided, § 1462 made criminal, under the Roth-Memoirs definition of “obscenity,” the knowing receipt of a film from interstate commerce if:
“(a) the dominant theme of the material taken as a whole appeals to a prurient interest in sex; (b) the material is patently offensive because it affronts contemporary community standards relating to the description or representation of sexual matters; and (c) the material is utterly wihout redeeming social value.”383 U.S. at 418 ,86 S.Ct. at 977 .
After Miller, appellant’s act was criminal if:
“(a) . . . ‘the average person, applying contemporary community standards’ would find that the work, taken as a whole, appeals to the prurient interest . . . ; (b) . . . the work depicts or describes, in a patently offensive way, sexual conduct specifically defined by the applicable state law; and (c) . . . the *566 work, taken as a whole, lacks serious literary, artistic, political, or scientific value.”413 U.S. at 24 ,93 S.Ct. at 2615 .
We think it is beyond controversy that the third prong of the
Miller
test expanded the field of potential criminal liability; indeed, the test was explicitly adopted to ease the prosecutor’s burden.
Miller,
at 22,
“Indeed, an unforeseeable judicial enlargement of a criminal statute, applied retroactively, operates precisely like an ex post facto law, such as Art. I, § 10, of the Constitution forbids. An ex post facto law has been defined by this Court as one ‘that makes an action done before the passing of the law, and which was innocent, when done, criminal; and punishes such action,’ of ‘that aggravates a crime or makes it greater than it was, when committed.’ Calder v. Bull, 3 Dali. 386, 390,1 L.Ed. 648 . If a state legislature is barred by the Ex Post Fac-to Clause from passing such a law, it must follow that a State Supreme Court is barred by the Due Process Clause from achieving precisely the same result by judicial construction. Cf. Smith v. Cahoon,283 U.S. 553 , 565,51 S.Ct. 582 ,75 L.Ed. 1264 . The fundamental principle that ‘the required criminal law must have existed when the conduct in issue occurred,’ Hall, General Principles of Criminal Law (2d ed. 1960), at 58-59, must apply to bar retroactive criminal prohibitions emanating from courts as well as from legislatures. If a judicial construction of a criminal statute is ‘unexpected and indefensible by reference t'o the law which had been expressed prior to the conduct in issue,’ it must not be given retroactive effect.”
Bouie v. City of Columbia,
*567
Moreover, appellant’s entitlement to have his conduct judged by the more favorable pr
e-Miller
test is implicitly mandated by the course followed by the Court in reviewing the
pre-Miller
conviction of the petitioner in Hamling v. United States,
We turn to those of appellant’s other contentions which are not mooted by the need for a retrial.
Appellant's attack on the constitutionality of 18 U.S.C. § 1462 is now foreclosed by the decision in Hamling.
Appellant’s attack' on the two search warrants is without merit. Read in a common-sense manner,
see
United States v. Ventresca,
*568
Appellant’s final contention is that, absent an indictment, the magistrate was without statutory jurisdiction to hold a preseizure adversary hearing to determine the probable obscenity of the film, and that therefore no valid adversary hearing was held, the warrant was invalid, and the seized film should be suppressed. We agree with the Second Circuit that F.R.Crim.P. 41, which establishes procedures and requirements for issuance of warrants (procedures which may be employed prior to indictment), may be read here to authorize the magistrate to fashion and employ procedures for determining probable cause for the issuance of the warrant. Perial Amusement Corp. v. Morse,
The judgment of conviction is reversed, and the matter remanded for further proceedings consistent with Hamling and the views expressed herein.
Notes
The Ilonorable William T. Sweigert, United States District Judge for the Northern District of California, sitting by designation.
. Roth v. United States,
. As it need not prove that appellant knew the legal obscenity of the film removed from interstate commerce, knowledge of the general character or contents of the material being sufficient to meet the scienter requirement of 18 U.S.C. § 1462, Hamling v. United States,
. Appellant’s reliance on Marcus v. Search Warrants,
. We reject appellant’s contention that the seized film is inadmissible absent a showing that it is the actual print received from interstate commerce on the date alleged in the indictment. The government, if it can, may establish by other proof that a print of the same film was received from interstate commerce as alleged, and may use any copy of the film allegedly received to establish the obscenity of the film actually shipped in commerce. Whether or not the prints are identical is of course then a collateral subject for the jury’s determination.
