Today we must decide whether a pretrial application for a writ of prohibition addressed to a state supreme court satisfies the exhaustion requirement which is a prerequisite before seeking *175federal habeas corpus relief.1 In recognition of the value of the underlying policies which buttress the exhaustion rule, requiring an initial presentation of ha-beas corpus claims to the state court system, we hold that it does not.

Beatrice Tooten, a non-physician, is charged under the Florida abortion statute2 with performing an illegal abortion in an unapproved facility. In response to the charges she moved to dismiss contending that the Florida statute is unconstitutional.3 The trial court denied her motion. She then applied to the Florida Supreme Court for a writ of prohibition alleging that the unconstitutional abortion statute deprived the trial court of jurisdiction. Although the extraordinary writ of prohibition will lie to bar a state criminal prosecution based upon an unconstitutional statute,4 the Florida Supreme Court summarily denied her application.5

On this appeal she argues that she has properly presented Florida’s highest state court with an opportunity to pass upon her claim, and thus she has exhausted her state remedies. The federal district court rejected her exhaustion contention and suggested that she allow the Florida state courts a chance to consider her arguments during the trial and appellate process. We affirm.

Although federal courts have the power to release state prisoners before trial, the exhaustion requirement must be fulfilled.6 The exhaustion doctrine is a judicially crafted requirement, now considered jurisdictional,7 which is firmly rooted in sound considerations of federal-state comity. Two significant interests have been identified which are protected by the policy of exhaustion.

First, exhaustion preserves the role of the state courts in the application and enforcement of federal law. Early federal intervention in state criminal proceedings would tend to remove federal questions from the state courts, isolate those courts from constitutional issues, and thereby remove their understanding of and hospitality to federally protected interests. Second, exhaustion preserves orderly administration of state judicial business, preventing the interruption of state adjudication by federal habeas proceedings. It is important that petitioners *176reach state appellate courts, which can develop and correct errors of state and federal law and most effectively supervise and impose uniformity on trial courts.8

These fundamental interests underlying the exhaustion doctrine are satisfied by giving the state an initial opportunity to pass upon and correct alleged violations of its prisoners’ federal rights.9 Whatever may be the merits of her constitutional argument, the appellant has not presented the Florida courts with such an “initial opportunity” to promulgate a final and definitive ruling. Therefore, appellant’s reliance on this court’s recent decision in Fain v. Duff10 is misplaced. In Fain the Florida courts on direct appeal fully considered the petitioner’s double jeopardy contention; there was nothing more for the courts of Florida to say or do.11 In the instant case, however, the Florida courts have yet to finally adjudicate the issue presented here. The writ of prohibition is an extraordinary writ. Even though an extraordinary writ may have been denied before trial upon the appellant’s arguable constitutional claim, the Florida courts on direct appeal may adopt her position.

The appellant contends that a direct appeal cannot vindicate her federal rights because she claims a right to freedom from an unconstitutional prosecution and the subjection to the rigors of a criminal trial. To support this position she relies again on Fain v. Duff. There the court noted that Fain was not merely asserting a federal defense to a state prosecution. Rather he was asserting a double jeopardy claim, and that is a right to be free from a second prosecution, not merely a second punishment. This distinction provided further support for the Fain decision, but there the petitioner was entitled to a pretrial writ of habeas corpus not only because the claim was double jeopardy but also because he had exhausted his state remedies.

Interruption of the state proceedings in the present case would seem to frustrate the very policies upon which the exhaustion doctrine is based.12 Exercising jurisdiction here would deprive the state appellate courts of a meaningful opportunity to analyze appellant’s federal claims and to supervise the trial courts in the state judicial system. In Braden v. Judicial Circuit Court of Kentucky13 a pre-trial habeas corpus writ was granted, but the court found that the petitioner had exhausted all available state court opportunities to establish his right to a speedy trial. Moreover, rather than trying to interrupt the orderly functioning of the state judicial process, as is the case here, Braden came to the federal court in order to enforce Kentucky’s obligation to provide him with a forum. The Braden court carefully emphasized that nothing it said would permit the derailment of a pending state proceeding by an attempt to litigate constitutional defenses prematurely in federal court.

Challenging the constitutionality of the Florida statute appears to be merely a classic example of a federal defense to a state prosecution. Federal habeas corpus does not lie, absent special circumstances, to adjudicate the merits *177of an affirmative defense to a state criminal charge prior to a judgment of conviction by a state court.14 The appellant maintains that “special circumstances” are present here in that she has attempted to have her claim vindicated by the state courts and that prior decisions 15 clearly establish the viability of her argument. This situation does not present the special circumstances envisioned by the courts.16 As previously explained we do not regard her application for a writ of prohibition as an adequate attempt to obtain state vindication. In the somewhat analogous area of abstention a pending state criminal prosecution will not be enjoined absent “very unusual situations, . . . necessary to prevent immediate irreparable injury.”17 Irreparable injury will not ordinarily be deemed to be present where the threat to the plaintiff’s federally protected rights can be eliminated by the defense of a single criminal prosecution.18 Furthermore, special circumstances are not necessarily established by the alleged infallibility of the federal claim. Indeed, without reaching the merits of appellant’s constitutional argument we take note of the fact that if her position is as clearly correct as she suggests, the Florida courts are surely capable of recognizing and vindicating her position.

Federal habeas corpus should not be used as a “pretrial motion forum for state prisoners.”19 To adopt appellant’s contentions in this case would create just such a result. Accordingly the decision of the district court is affirmed.

Affirmed.
