This is an appeal from an order of the district court granting a writ of habeas corpus and dismissing petitioner from the custody of a governor’s warrant directing his rendition to Florida. Petitioner, who is serving a Massachusetts sentence at the Massachusetts Correctional Institution at Walpole, is charged in Florida with the crimes of breaking, entering and grand larceny.
On December 28, 1971, the Governor of Florida sent a formal demand for petitioner’s rendition to the Governor of Massachusetts. The papers accompanying this demand included certified copies of a two-count information executed by a Florida prosecutor charging petitioner and another with breaking and entering a certain dwelling in Miami Beach and with the larceny of certain personal effects on October 17, 1971; an affidavit of a Miami Beach police officer repeating the allegations of the information and stating that they were within the affiant’s knowledge; and a capias ordering petitioner’s arrest by Florida sheriffs to answer to the charges in the information.
On September 28, 1972, the Governor of Massachusetts issued a warrant for petitioner’s arrest and delivery to the custody of Florida agents. Petitioner sought a state writ of habeas corpus, complaining in part that his arrest on the Massachusetts Governor’s warrant would violate the fourth amendment for want of any showing of probable cause in the papers forwarded by the Governor of Florida. The Superior Court dismissed the petition, and the Supreme Judicial Court affirmed.
In re Ierardi,
*930
Mass.,
Following this decision petitioner filed his federal habeas corpus petition in the district court. Shortly thereafter the United States Supreme Court decided
Gerstein v. Pugh,
In granting the writ in the present case, the district court found that Ger-stein “substantially changed the state of the law on which the Supreme Judicial Court relied in its decision herein.” The court held that extradition warrants are required to comply with fourth amendment standards and that the instant warrant was not based on probable cause and therefore did not comply.
We agree with the district court that
Gerstein
requires a judicial determination of probable cause as a prerequisite to interstate extradition. After
Ger-stein
such a determination must precede “any significant pretrial restraint of liberty,”
Against this, respondents point to two governmental interests at stake in extradition which were not considered in Ger-stein and which, respondents say, would be defeated by reading Gerstein to require a pre-rendition judicial determination of probable cause. These are the interests of comity in transactions between sister states, 1 and of efficiency in bringing to justice criminals who have fled interstate. 2 We agree that these interests are of the utmost importance, but not that they are significantly burdened by imposition of Gerstein’s requirement in this context. Respondents seem to assume that if a judicial determination of probable cause must precede *931 extradition, it must be provided by the courts of the asylum state, where the fugitive is held. This is not so. Ger-stein explicitly rejected the need for adversarial procedures; it required only the neutral and detached judgment of a judicial officer or tribunal, and contemplated that this could be provided before as well as shortly after arrest. 3 Thus nothing in Gerstein prevents the demanding state from providing the requisite pre-rendition determination of probable cause.
With this in mind, we do not believe it compromises the principles of comity to require a judicial determination of probable cause before rendition. Such a determination is fully consistent with reliance by the asylum state on the regularity of the demanding state’s procedures. If, for example, the papers submitted by Florida were to show that a judicial officer or tribunal there had found probable cause, Massachusetts would not need to find probable cause anew, nor would it need to review the adequacy of the Florida determination. Instead, it would be entitled to rely on the official representations of its sister state that the requisite determination had been made; thus in our view Massachusetts may credit an arrest warrant shown to have issued upon a finding of probable cause in Florida just as it would credit a Florida indictment. 4
Nor do we believe that a prior judicial determination of probable cause in this context presents such an obstacle to efficient law enforcement as to justify postponing the determination until after rendition. We recognize that the fourth amendment standards governing arrest represent “a necessary accommodation between the individual’s right to liberty and the State’s duty to control crime.”
Gerstein, supra,
*932 Here the rendition demand was based on a Florida information that, as Ger-stein makes clear, does not embody the prior judicial determination of probable cause required by the fourth amendment, and the requisite determination has yet to be made. 6
Affirmed.
Notes
.
See In re Ierardi,
Mass.,
“[Pjrinciples of comity operate against inquiry into the criminal procedures of the demanding State. ... It would seem that we should be hesitant about examining the constitutional basis of another State’s actions, and we do not agree that the Fourth Amendment requires that we do.”
.
See In re Maldonado,
Mass.,
“[I]nterstate extradition is a summary executive procedure whose effect is essentially to enlarge the territorial area for lawful arrest, the asylum jurisdiction being added to the demanding jurisdiction. . . .”
.
See Gerstein v. Pugh,
. We do not suggest that a judicial determination of probable cause in the asylum state would not provide an alternative means of satisfying fourth amendment standards.
See Kirkland v. Preston,
. Nearly all states have enacted the Uniform Criminal Extradition Act, see M.G.L., ch. 276, at 74-75; 1975 Supp., at 16. Section 3 of the Uniform Act, as enacted in Massachusetts, M.G.L., ch. 276, § 14, provides that the demand for rendition must be accompanied: “by a copy of an indictment found, or of an information supported by affidavit, in the demanding state, or by a copy of an affidavit made before a magistrate of such state, and by a copy of the warrant which was issued thereon
. Counsel for respondents conceded in argument before us that the affidavit accompanying the demand provided no independent basis for a judicial finding of probable cause.
