We must decide whether a bankruptcy court, which had approved a settlement agreement, had jurisdiction to interpret that agreement in an adversary proceeding between two creditors brought after the closing and dismissal of the underlying bankruptcy case. We conclude that, in the circumstances of this case, the bankruptcy court lacked jurisdiction and we therefore reverse the district court’s order.
FACTS
Appellant Sea Hawk Seafoods, Inc., (“Sea Hawk”) owns a seafood processing plant in Valdez, Alaska. In April 1995, Sea Hawk brought suit in the Alaska Superior Court against Valdez Fisheries Development Association (‘VFDA”) for breach of contract arising out of a failed agreement to sell its processing plant. In August 1997, the Superior Court entered judgment for Sea Hawk against VFDA for over $2 million. Alaska’s Division of Investments then called VFDA’s loans aggregating in excess of $7 million. In response, VFDA delivered to the State approximately $1.65 million in cash and over $400,000 in accounts receivable.
Sea Hawk then filed a petition in the Superior Court naming the State of Alaska as a party and challenging the transactions between VFDA and the State as void under state fraudulent conveyance law. The court did not rule on the petition. After the Alaska Supreme Court denied VFDA’s request for a stay of the judgment against it, VFDA filed for Chapter 11 protection *547 and filed a Notice of Automatic Stay. Sea Hawk’s motion for relief from the automatic stay was denied.
After a period of negotiation, Sea Hawk and VFDA in 1999 entered into a settlement agreement (the subject of this proceeding). The State was not a party to that agreement. The agreement provided, among other things, that the parties would “dismissf] all pending litigation between the two parties, with prejudice” and that the bankruptcy court shall have “continued jurisdiction over ... the interpretation ... of ... th[e] Settlement Agreement.” The bankruptcy court approved the settlement agreement and dismissed the Chapter 11 proceeding. On June 24, 1999, the court entered a final decree closing the VFDA bankruptcy.
Sea Hawk promptly returned to state court and sought a ruling on its fraudulent conveyance claim against the State. The State objected on the ground that the settlement agreement protected it as well as VFDA. The court directed the parties to seek a determination of the scope of the agreement from the bankruptcy court. The Alaska Supreme Court affirmed that ruling. Sea Hawk then moved to reopen the bankruptcy case to obtain a determination of whether the agreement released its fraudulent conveyance claim against the State. At the direction of the court, Sea Hawk filed an adversary proceeding against the State. The court ruled that it had jurisdiction over this proceeding as one related to the bankruptcy. After further proceedings, the court entered a stipulated final order finding that the settlement agreement released Sea Hawk’s claim against the State, but preserving Sea Hawk’s objection to the bankruptcy court’s jurisdiction. Sea Hawk appealed to the district court, which affirmed, but on the ground that by approving the settlement agreement, the bankruptcy court retained jurisdiction to interpret it. This timely appeal followed.
DISCUSSION
We review a bankruptcy court’s determination of its jurisdiction de novo.
In re G.I. Indus., Inc.,
I. “RELATED TO” JURISDICTION
The bankruptcy court held that it had jurisdiction over Sea Hawk’s adversary proceeding against the State under 28 U.S.C. § 1334(b) (2000). That section grants district courts (and bankruptcy courts by reference) “original but not exclusive jurisdiction of all civil proceedings ...
related to cases under title 11.”
§ 1334(b) (emphasis added). In
In re Fietz,
this Court adopted the Third Circuit’s articulation of the test for determining whether a civil proceeding is related to bankruptcy, stating that an action is related to bankruptcy if
“the outcome of the proceeding could conceivably have any effect on the estate being administered in bankruptcy.”
Here, when Sea Hawk filed its adversary proceeding, VFDA’s Chapter 11 case had been dismissed and a final decree entered. When the bankruptcy court later reopened the bankruptcy case, it did so “for the limited purpose of making a determination of whether the Settlement Agree
*548
ment ... releases Sea Hawk’s state court claims against the State of Alaska.” That determination could not conceivably “alter the debtor’s rights, liabilities, options, or freedom of action ... [or] in any way impact[] upon the handling and administration of the bankrupt estate.”
Fietz,
The State argues that to preserve the bankruptcy court’s ability to interpret its prior rulings, a different standard applies to postconfirmation proceedings. The Third Circuit, after reviewing the post-confirmation cases, concluded that “the essential inquiry appears to be whether there is a close nexus to the bankruptcy plan or proceeding sufficient to uphold bankruptcy court jurisdiction.”
In re Resorts Int'l. Inc.,
This is not a proceeding falling within the rationale of the close nexus test. Here, there was no confirmed plan and there is no claim that the dispute between two creditors, Sea Hawk and the State, would have any effect on the now-closed bankruptcy estate. The bankruptcy court has no role in the resolution of the creditors’ dispute, and it is involved only fortuitously because the dispute implicates the terms of a settlement agreement approved by the court as a precondition of the dismissal of VFDA’s bankruptcy. But that agreement has been fully implemented with respect to VFDA. 1
The bankruptcy court did not consider dismissal of VFDA’s bankruptcy to automatically divest it of jurisdiction over a related case. It reasoned that after dismissal, the court has discretion to retain jurisdiction over a related proceeding, citing
In re Carraher,
Carraher does not support the bankruptcy court’s decision. It stands for the proposition that a bankruptcy court may retain jurisdiction over a related proceeding pending at the time of the dismissal of the bankruptcy case. It does not support the assertion of bankruptcy jurisdiction over a proceeding initiated subsequent to the dismissal of the bankruptcy case. Thus, had the state court fraudulent conveyance action been removed to the bank *549 ruptcy court while the bankruptcy ease was open, that court, in its discretion, could have retained jurisdiction after the dismissal of the bankruptcy ease. But the fact that it might have been removed does not provide a basis for bankruptcy jurisdiction over a later filed proceeding.
II. RETAINED JURISDICTION OVER THE SETTLEMENT AGREEMENT
The district court affirmed the bankruptcy court’s order on a different theory, holding that when that court approved the settlement agreement between VFDA and Sea Hawk, it was thereby adopting the terms of the settlement agreement as part of its order. This, it held, was sufficient for it to have implicitly retained jurisdiction over that agreement.
Bankruptcy courts are courts of limited jurisdiction. Having concluded that there was no “related to” jurisdiction over this proceeding, we next consider whether the bankruptcy court had ancillary jurisdiction. Ancillary jurisdiction may rest on one of two bases: (1) to permit disposition by a single court of factually interdependent claims, and (2) to enable a court to vindicate its authority and effectuate its decrees.
Kokkonen v. Guardian Life Ins. Co. of Am.,
Here, the bankruptcy
court
entered an order approving the settlement agreement and a second order dismissing the case, reciting the prior approval and stating that “[t]he conditions of the settlement hav[e] been fulfilled.” The orders neither “retain[ed] jurisdiction” over the settlement agreement nor incorporated “the parties’ obligation to comply with [its] terms.”
Id.
at 381,
The State seeks to distinguish
Kokkonen
on two grounds. First, it argues that
Kok-konen
does not apply because the settlement agreement here required and received the bankruptcy court’s approval. But
Kokkonen
specifically states that “[t]he judge’s mere awareness and approval of the terms of the settlement agreement do not suffice to make them part of his order.”
Id.
It noted that even in a dismissal under Federal Rule of Civil Procedure 41(a)(2), which requires a court order, enforcement of the settlement agreement is for state courts in the absence of a specific retention of jurisdiction or a condition requiring the parties’ compliance with the terms of the settlement agreement.
Id.
at 381-82,
Next, the State argues that
Kokkonen
involved enforcement of a settlement agreement, while this proceeding is brought to interpret an agreement. It
*550
relies on dicta in two Ninth Circuit cases stating that a bankruptcy court “retains subject matter jurisdiction to
interpret
orders entered prior to dismissal of the underlying bankruptcy case.”
In re Taylor,
So far as the application of the Kokko-nen principle is concerned, we find no relevant difference between a proceeding to enforce a settlement agreement and one to interpret it.
We have considered the other arguments advanced by the State and find them without merit. We conclude that because this proceeding between Sea Hawk and the State is not one to “vindicate the [court’s] authority” or to “effectuate its decree,”
Kokkonen,
CONCLUSION
For the reasons stated, the order of the district court is REVERSED.
Notes
. The bankruptcy court itself noted, in an order ending the accrual of the Trustee’s fees, that this dispute does "not appear to affect the bankruptcy estate or the debtor.”
