Missouri prisoner Ricardo Carmichael filed this federal habeas action asserting his 1997 probation revocation proceedings did not comply with procedural due process. In response, the State of Missouri asserted that *1045 Carmichael had not exhausted his state-court remedies under Missouri Supreme Court Rule 91, and that there is no time limitation for filing a Rule 91 petition. Carmichael conceded he had mistakenly filed his petition in federal rather than state court, and sought to have the federal action either held in abeyance or dismissed without prejudice. The district court ordered the action “stayed for a period of 90 days so [Carmichael] may seek habeas corpus relief in the Missouri Court of Appeals under ... Rule 91.” The State appeals the order staying the action for ninety days. We reverse and remand.
Initially, Carmichael contends we lack jurisdiction to review the district court’s ruling because it is not a final order. See 28 U.S.C. § 1291 (1994). The State contends we have jurisdiction to review the ruling under the collateral order doctrine.
Although our jurisdiction is generally limited to reviewing a district court’s final decisions ending litigation on the merits,
see id.,
we can immediately review a small class of collateral orders that do not terminate the underlying lawsuit,
see Cohen v. Beneficial Indus. Loan Corp.,
Applying these factors, the only circuit to consider the question has held a district court’s order holding a habeas petition in abeyance pending exhaustion of state remedies is an appealable collateral order.
See Christy v. Horn,
Turning to the merits, we conclude the district court lacked power to enter a ninety-day stay for Carmichael to pursue state remedies. We have already held that a district court has no authority to hold a habeas petition containing unexhausted claims in abeyance absent truly exceptional circumstances, such as when state remedies are inadequate or fail to afford a full and fair adjudication of federal claims, or when exhaustion in state court would be futile.
See Victor v. Hopkins,
Carmichael also asserts the record does not show his petition contains unex-hausted claims. With respect to every claim in his petition, however, Carmichael had the burden to show that all available state remedies had been exhausted or that exceptional circumstances existed.
See Darr v. Burford,
*1048 In sum, we conclude the district court’s ruling staying Carmichael’s federal habeas action for ninety days is an appealable collateral order, and the district court should have dismissed Carmichael’s petition without prejudice for failure to exhaust state remedies. Given the State’s representations in the district court and on appeal, Carmichael should face no problem with a time limitation for filing his Rule 91 petition in state court. We thus reverse and remand for entry of an order consistent with this opinion.
