This appeal follows an order of the district court affirming the bankruptcy court's denial of an objection to a motion for final decree. The objection was filed by Marcus Hook Business and Commerce Center Limited ("MHBCC"), Marcus Hook Corporation ("MHC"), Bell Savings Bank ("Bell"), and T.A. Title Company ("T.A. Title") (collectively the "Purchaser") in response to a motion for final decree filed by the debtor, Marcus Hook Development Park, Inc. ("MHDP"). At the center of the dispute are conflicting orders of the bankruptcy court which alternately approved the sale of a piece of property, free of any liens, to the Purchaser's predecessor in interest, and then reimposed a lien after the sale had been made. We will reverse the district court and order it to remand the case to the bankruptcy court so that the bankruptcy court may resolve this controversy.

In December, 1983, MHDP filed a petition for relief under Chapter 11 of the Bankruptcy Code. 11 U.S.C. §§ 1101-74 (1988). MHDP's sole asset was 35 acres of developed industrial real estate located in the Borough of Marcus Hook, Delaware County, Pennsylvania (the "property"). Delaware County (the "County") held a $125,000 tax lien against that property. By order of the bankruptcy court, one acre of the property was subsequently sold at a public bankruptcy sale on June 4, 1985.

Thereafter, MHDP began negotiations with Dennis Marchuk regarding the sale of the other thirty-four acres. On July 17, 1986, MHDP filed a motion to sell its remaining acreage to Marchuk free and clear of liens and encumbrances. All creditors, including the County, were served with a notice of the proposed sale. After receiving notice, the County advised MHDP that it would waive its priority tax claim and agreed to be treated as an unsecured creditor. No objection to the sale was ever filed by the County.

An order confirming the sale to Marchuk was entered by the bankruptcy court on August 14, 1986. That order expressly stated that "said sale is free and clear of all mortgages, judgments, liens and encumbrances." In addition, the August 14 order provided that the sale was duly advertised, that proof of publication and service had been filed with the bankruptcy court, and that notice of the sale had been given to creditors and other parties in interest.

Before the closing, Marchuk assigned his rights in the property to MHBCC. On November 24, 1986, closing was held, pursuant to which MHBCC received a special warranty deed for $560,000. MHBCC granted a mortgage upon the property to Bell. T.A. Title held the $560,000 in escrow, and provided title insurance to both MHBCC and Bell. MHC is the successor in title to MHBCC.

A month-and-a-half after the closing, MHDP and the Official Unsecured Creditor's Committee filed a disclosure statement in support of the proposed plan for reorganization. The disclosure statement provided that the "Debtor's real estate was sold under and subject to the continuing lien of the County of Delaware. The County's taxes shall therefore be dealt with by the purchaser of the property and the County shall not receive any dividend on account of its claims against the estate." Moreover, it stated that the County "shall continue to hold a lien against the property after the sale of the real estate. This claim will be dealt with by the purchaser. The County of Delaware will not receive any dividend from the estate." Despite the conflict between the August 14 order and the disclosure statement, the bankruptcy court entered an order on February 11, 1987, which approved the disclosure statement. The February 11 order required that all parties in interest be served with the disclosure statement, but it is not clear from the record if the Purchaser was so served.

On May 7, 1990, more than three years after the February 11 order, MHDP filed a motion for final decree. Upon being served with this motion, the Purchaser filed a timely objection. Specifically, the Purchaser pointed out that the August 14 order and the February 11 order were inconsistent with each other, and requested that the bankruptcy court remedy the problem. After a hearing, the bankruptcy court granted MHDP's motion for final decree. The bankruptcy court overruled the Purchaser's objection for two stated reasons. First, it characterized the basis for the objection as a dispute between non-debtors, and held that such a dispute was neither a core proceeding nor a related proceeding. Second, the bankruptcy court held that it had no authority to vacate the February 11 order at this late stage of the proceedings. Thus, the bankruptcy court never dealt with the merits of the Purchaser's objection, denying relief on the grounds that it had no jurisdiction.

The Purchaser then appealed to the district court. Reasoning that the bankruptcy court's findings were not clearly erroneous, even though no such findings appear in the bankruptcy court's orders, the district court affirmed the final decree. It would therefore seem that the district court affirmed on the merits although the bankruptcy court never addressed the merits. Subsequently, this appeal was timely filed.1

First and foremost, this is a case of common sense. There are two bankruptcy court orders which clearly contradict each other. The first says that the Purchaser acquired the debtor's property free and clear of all liens; the second reimposes the County's tax lien. Obviously, both orders cannot be given effect, at least not in this world. Presented with this rather confusing state of affairs, the Purchaser logically went to the source of the problem, the bankruptcy court, and requested appropriate relief. Stating that it lacked jurisdiction, the bankruptcy court took no action on the Purchaser's objection. On appeal, the district court reached the merits, affirming bankruptcy court findings that do not appear in the bankruptcy court's orders.

"As an appellate court twice removed from the primary tribunal, we review both the factual and the legal determinations of the district court for error. Universal Minerals, Inc. v. C.A. Hughes & Co., 669 F.2d 98, 101-02 (3d Cir.1981). Our vantage point is identical to that of the district court ... 'so we review the bankruptcy court's findings by the standards the district court should employ, to determine whether the district court erred in its review.' Id. at 102. Thus, in reviewing the district court's review of the bankruptcy court's factual findings, we, like the district court, employ the 'clearly erroneous' standard.... [T]he district court's legal determinations receive no presumption of correctness.

Resyn Corp. v. United States, 851 F.2d 660, 664 (3d Cir.1988).2

First, we turn to the question of the bankruptcy court's jurisdiction. Although not clearly stated, one of the rationales cited by the bankruptcy court for its denial of the Purchaser's objection was a lack of subject-matter jurisdiction. It is well-settled that the bankruptcy court potentially has jurisdiction over four types of title 11 matters, pending referral from the district court:3 (1) cases under title 11, (2) proceedings arising under title 11, (3) proceedings arising in a case under title 11, and (4) proceedings related to a case under title 11. In re Wolverine Radio Co., 930 F.2d 1132, 1141 (6th Cir.1991); Matter of Wood, 825 F.2d 90, 92 (5th Cir.1987). See 28 U.S.C. § 1334.4 The first of these categories, cases under Title 11, "refers merely to the bankruptcy petition itself." Matter of Wood, 825 F.2d at 92. This action goes beyond the bankruptcy petition. See In re Wolverine Radio Co., 930 F.2d at 1141 and n. 14.

Thus, we are required to determine if this action falls within one of the other three categories, thereby conferring jurisdiction upon the bankruptcy court. It is not necessary, though, to fit the proceeding into one of these particular categories, since "they operate conjunctively to define the scope of jurisdiction." Matter of Wood, 825 F.2d at 93. Accord, In re Wolverine Radio Co., 930 F.2d at 1141. Hence, we need only determine "whether a matter is at least 'related to' the bankruptcy." Id.

A proceeding is related to bankruptcy if "the outcome of that proceeding could conceivably have any effect on the estate being administered in bankruptcy," Pacor, Inc. v. Higgins, 743 F.2d 984, 994 (3d Cir.1984) (emphasis in original). Accord In re Fietz, 852 F.2d 455, 457 (9th Cir.1988); Matter of Wood, 825 F.2d at 93; In re Dogpatch U.S.A., Inc., 810 F.2d 782, 786 (8th Cir.1987); In re A.H. Robins Co., Inc., 788 F.2d 994, 1002 n. 11 (4th Cir.), cert. denied, 479 U.S. 876, 107 S. Ct. 251, 93 L. Ed. 2d 177 (1986); In re Salem Mortgage Co., 783 F.2d 626, 634 (6th Cir.1986). A key word in this test is "conceivable." Certainty, or even likelihood, is not a requirement. In re Wolverine Radio Co., 930 F.2d at 1143. Bankruptcy jurisdiction will exist so long as it is possible that a proceeding may impact on "the debtor's rights, liabilities, options, or freedom of action" or the "handling and administration of the bankrupt estate." In re Smith, 866 F.2d 576, 580 (3d Cir.1989). Accord Pacor, Inc. v. Higgins, 743 F.2d at 994.

We hold that the present proceeding is related to bankruptcy. A party moving for final decree asks that the case be closed because the estate has been fully administered. 11 U.S.C. § 350 (1988); Bankr.R. 3022. Should the objection to the motion for final decree be sustained, the bankruptcy court would retain its power to issue any orders necessary to administer the estate. Bankr.R. 3020(d). See 11 U.S.C. § 105(a) (1988); In re Bryant, 111 B.R. 474, 477 n. 2 (E.D.Pa.1990) (bankruptcy court still has jurisdiction even though debtor's underlying bankruptcy had been discharged because the case was not closed). Certainly, additional orders might potentially effect the bankrupt estate. For example, the bankruptcy court could set aside the sale pursuant to Fed.R.Civ.P. 60(b)(6) and Bankr.R. 9024. See Matter of Met-L-Wood Corp., 861 F.2d 1012, 1018 (7th Cir.1988), cert. denied 490 U.S. 1006, 109 S. Ct. 1642, 104 L. Ed. 2d 157 (1989) ("confirmed sales--which are final judicial orders--can be set aside" under Rule 60(b), which is made applicable to bankruptcy proceedings by Bankruptcy Rule 9024).5 Less drastic measures include entering an order which affirms the August 14 order notwithstanding other orders to the contrary. Indeed, an order of this sort may be required if final decree is to be granted; it is doubtful that an estate can be fully administered, consistent with Rule 3022, until conflicting orders are reconciled. Under these circumstances, it cannot be argued that the present proceeding would have no conceivable effect on the estate.6 Contrary to the bankruptcy court's determination, then, it does have jurisdiction over this matter.

MHDP relies on In re Hall's Motor Transit Co., 889 F.2d 520 (3d Cir.1989), for the proposition that the bankruptcy court does not have subject-matter jurisdiction. At first blush, Hall's Motor seems to help MHDP. In Hall's Motor, a purchaser obtained property from the debtor in bankruptcy court. Several months later, the sale was closed. During the interim, the property was rezoned in a manner unfavorable to the purchaser. Although aware of the rezoning, the purchaser took no action before the closing. Thereafter, the purchaser requested declaratory and injunctive relief from the bankruptcy court that would prohibit enforcement of the new zoning ordinance. We held that the bankruptcy court could not entertain the complaint, reasoning that its "jurisdiction does not follow the property, but rather, lapses when the property leaves the debtor's estate." Id. at 522. Here, the property has also left the estate.

Although Hall's Motor accurately summarizes the law, it is clearly inapposite to the matter before us. The most important difference between the two cases arises from the nature of the respective proceedings. In Hall's Motor, the purchaser acquired the property pursuant to a court order which apparently did not address the zoning issue. Moreover, the Hall's Motor purchaser had notice of the rezoning prior to closing the sale, and indeed, the sale was "affirmed by the bankruptcy court after the rezoning had occurred." Id. No subsequent order addressed zoning. The purchaser, then, had no complaint with the sale or any attendant judicial action. Instead, its attention was focused on the property itself; the purchaser's pivotal argument, we noted, was "that the right to use the property as [it was used under the old zoning ordinance] is a right belonging to [the debtor's] estate which came within the jurisdiction of the bankruptcy court as part of the estate." Id. Since the property had left the estate, we correctly refused jurisdiction.

The present case offers a sharp contrast. By means of the August 14 order, the bankruptcy court confirmed the sale of MHDP's property to the Purchaser "free and clear of all ... liens." But without any explanation, and seemingly without notice to the Purchaser, the County lien was reimposed by the February 11 order. After discovering that its property was subject to the County's lien, the Purchaser objected. However, the objection was not directed to the property, but to the judicial orders controlling the disposition of that property. Unlike the requested relief in Hall's Motor, then, which did not contest the order of sale and which therefore only tangentially touched the bankruptcy proceedings, the relief sought here directly implicates the conflicting bankruptcy court orders.

This is an important difference. Section 105(a) of the Bankruptcy Code, 11 U.S.C. § 105(a), permits the bankruptcy court to "issue any order, process, or judgment that is necessary or appropriate to carry out the provisions of this title." It was this section which gave the bankruptcy court the power to issue the August 14 and February 11 orders. It is also this section which gives the bankruptcy court "the power and the jurisdiction to enforce its valid orders." In re Radco Merchandising Services, Inc., 111 B.R. at 688-89. Hall's Motor cannot possibly be read to take this grant away from the bankruptcy court. See Big Shanty Land Corp. v. Comer Properties, Inc., 61 B.R. at 282-83 (holding that bankruptcy court could enjoin transfer of bankrupt estate's property even though the property had already been transferred out of debtor's estate where that transfer violated earlier court orders). Since the Purchaser's objection merely asks the bankruptcy court to enforce the August 14 order approving a sale free and clear of liens, the bankruptcy court therefore has undisputed jurisdiction over the Purchaser's objection. Not only is the Purchaser's objection jurisdictionally correct, but it also makes perfect sense; given the conflicting nature of the two orders, only one can be enforced.

The bankruptcy court offered a second reason for its decision to deny the Purchaser's objection: the objection did not constitute a core proceeding. Whether a particular proceeding is core represents a question wholly separate from that of subject-matter jurisdiction. Under 28 U.S.C. § 157, a bankruptcy court might have jurisdiction over a proceeding, but still might not be able to enter final judgments and orders.

Section 157 provides the bankruptcy court with two levels of judicial power, depending on the type of proceeding before it. If a proceeding is "core," the bankruptcy court may "hear and determine the issues and may enter appropriate judicial orders and judgments subject to traditional appellate review." Weintraub & Resnick, supra note 3, at p 6.04 (summarizing 28 U.S.C. § 157(b)(1)). With respect to a "non-core" proceeding, the bankruptcy court's power is more limited. It may only hear the matter and submit proposed findings of fact and conclusions of law. These findings and conclusions are reviewed de novo by the district court. Any final orders or judgments must be entered by the district court, unless the parties and the district court agree otherwise. 28 U.S.C. § 157(c)(2). See In re Meyertech Corp., 831 F.2d 410, 416 (3d Cir.1987). See also Weintraub & Resnick, supra note 3, at p 6.04. Thus, to determine if the bankruptcy court has the power to provide the relief requested by the Purchaser, we must decide whether this action is a core or non-core proceeding. In re Wolverine Radio Co., 930 F.2d at 1144.

We hold that the objection to the motion for final decree is a core proceeding. While core proceedings are not statutorily defined, section 157(b)(2) does provide a non-exhaustive list of examples. 28 U.S.C. § 157(b)(2). See In re Meyertech Corp., 831 F.2d at 416; Matter of Wood, 825 F.2d at 95. Additionally, we have held that a " 'proceeding is core under section 157 if it invokes a substantive right provided by title 11 or if it is a proceeding that, by its nature, could arise only in the context of a bankruptcy case.' " Beard v. Braunstein, 914 F.2d 434, 444 (3d Cir.1990) (quoting Matter of Wood, 825 F.2d at 97). See In re Wolverine Radio Corp., 930 F.2d at 1144-45.

Depending on how the Purchaser's objection is characterized, it falls within the list of examples in section 157(b)(2). First, the purchaser's objection is expressly designed to determine the validity or extent of the County's lien against the property. Section 157(b)(2)(K), which states that "determinations of the validity, extent, or priority of liens" are core proceedings, therefore applies. By objecting to the motion for final decree, the Purchaser can also be viewed as trying to enforce the August 14 sale order. As such, the objection is directly analogous to section 157(b)(2)(N), which provides that "orders approving the sale of property" are core proceedings. Under either characterization, then, the Purchaser's objection is a core proceeding. See In re Meyertech Corp., 831 F.2d at 418 (proceeding is core because it comports with one of the examples provided by section 157).7

Not only does the Purchaser's objection fit under section 157(b)(2)(K) and (N), but it also satisfies the Beard v. Braunstein test. There exist two orders governing MHDP's estate, both of which were entered by the bankruptcy court during the course of a bankruptcy case. One order is contrary to the other, but no effort was made to explain the difference. Given these rather unique circumstances, we conclude without hesitation that the present proceeding could only arise in a bankruptcy case, and is therefore core. See In re Wolverine Radio Co., 930 F.2d at 1145 (proceeding is core because the issues arose as a result of a bankruptcy proceeding). As such, the bankruptcy court has at its disposal all the judicial tools necessary to address the merits of the Purchaser's objection.

A third and final reason suggested by the bankruptcy court for its denial of the purchaser's objection is impracticability. At this late stage of the bankruptcy case, reasoned the bankruptcy court, it would be "inappropriate" to rectify the problem created by the conflicting orders of August 14 and February 11. MHDP makes a related argument, contending that the appeal is moot because it would be impossible for a court to provide the relief sought.8 Indeed, if the bankruptcy court were required to vacate the sale of the property, order creditors to disgorge funds, vacate the order approving the disclosure statement, and vacate the order confirming the reorganization plan, we might be compelled to affirm. See In re Highway Truck Drivers & Helpers Local # 107, 888 F.2d at 299; Bankr.R. 8005.

But less draconian alternatives exist. All the bankruptcy court need do is hold a hearing, resolve the factual questions which remain in this case,9 and enter an appropriate order with findings of fact and conclusions of law explaining its decision. At worst, the County would be forced to forego its priority tax claim, a result not terribly unseemly, especially since the County has refused to participate in this case. In short, there are no equitable considerations which justify the bankruptcy court's decision, nor is the relief sought impracticable.

For all of the above reasons, we find that the bankruptcy court clearly erred in denying the Purchaser's objection. The bankruptcy court had subject-matter jurisdiction, the proceeding before it was core, and the relief sought was not barred by equitable concerns or impracticability. It follows that the district court also erred in affirming the bankruptcy court's decision. We will therefore reverse the order of the district court affirming the bankruptcy court's order granting the final decree, with instructions that it remand the case to the bankruptcy court for development of a record through an evidentiary hearing, if necessary, and for findings of fact in connection with its resolution of the present controversy. Costs taxed against MHDP.

HUTCHINSON, Circuit Judge, concurring.

I concur in the result the Court reaches in this case and join its mandate reversing the order of the district court and remanding the case to it with instructions that it in turn remand the case to the bankruptcy court for the development of a full record, including findings of fact to the extent necessary to eliminate the conflict between the bankruptcy court's order of sale free and clear of liens and its final decree purporting to reimpose a lien after it confirmed the sale of the property free and clear. I write separately to express my view that resolution of the conflict between the bankruptcy court's order of sale and its final decree should not operate to deprive a person who purchased the property directly from the bankruptcy court in good faith reliance on the order of sale, or subsequent good faith purchasers, of the right to enjoy the property free and clear of liens, in accordance with the confirmed order of sale.

I agree with the Court that the presence of conflicting orders distinguishes this case from In re Hall's Motor Transit Co., 889 F.2d 520 (3d Cir.1989). In Hall's Motor Transit, the purchaser at the bankruptcy sale sought the right to continue using the property for a motor freight terminal, Id. at 522, a right of use that was not mentioned or otherwise secured by the order of sale, Opinion of the Court, at 265-66. Here, the final decree may impinge on a right the order of sale directly confers on the purchaser. In Hall's Motor Transit, the bankruptcy court's jurisdiction over the property lapsed when the property left the debtor's estate. Hall's Motor Transit, 889 F.2d at 522 (citing Matter of Xonics, Inc., 813 F.2d 127, 131 (7th Cir.1987)). Here, the objection to the language of the final decree that purports to impose upon the purchaser liability for what is described as Delaware County's tax lien is related to the bankruptcy because modification or elimination of the final decree's provision concerning a county tax claim "could alter the debtor's rights, liabilities, options, or freedom of action ... and ... impact[ ] upon the handling and administration of the bankrupt estate." Pacor, Inc. v. Higgins, 743 F.2d 984, 994 (3d Cir.1984). I also agree with the Court that the present dispute about the validity and effect of the portion of the final decree that attempts to reimpose a lien upon property the estate had already sold free and clear is a core proceeding that the bankruptcy court has the power to hear and determine. See In re Meyertech Corp., 831 F.2d 410, 416 (3d Cir.1987); 28 U.S.C.A. § 157(b)(2)(K), (N) (West Supp.1991).

Nevertheless, since the property itself has left the estate, I believe the bankruptcy court's power to affect the rights of purchasers is limited. Indeed, the Court intimates as much at two places in its opinion. See Opinion of the Court, at 268 ("[I]f the bankruptcy court were required to vacate the sale of the property, order creditors to disgorge funds, vacate the order approving the disclosure statement, and vacate the order confirming the reorganization plan [in order to provide the relief sought], we might be compelled to affirm."); id. at 267 (the result on remand could be, "[a]t worst, [that] the county would be forced to forego its priority tax claim."). Thus, I do not believe the language in the Court's opinion concerning the general equitable powers of a bankruptcy court or its powers under Federal Rule of Civil Procedure 60(b)(6) and Bankruptcy Rule 9024 to relieve a party or a party's legal representative, in the interest of justice, from the consequences of a mistake in an order, judgment or decree is intended to open the way to modification of the order of sale in a manner that would adversely affect rights expressly granted to persons who have purchased the property so sold in good faith reliance upon the bankruptcy court's confirmed order. This is not to say that an order of sale can never be modified, pursuant to Rule 60(b)(6) or otherwise, if evidence is produced to show that the purchaser at the bankruptcy sale acted in bad faith or otherwise misled the court about the existence of potential liens like the tax lien Delaware County is said to hold or if the purchaser at the bankruptcy sale or any subsequent purchaser had otherwise entered into a binding and enforceable understanding with the debtor or the holder of the lien to assume responsibility for payment, without advising the bankruptcy court of that fact.

I do not believe, however, that such an understanding or agreement or misrepresentation by a purchaser at a bankruptcy sale should affect the rights of any subsequent good faith purchaser who lacked notice of that understanding or misrepresentation and relied on the terms of the bankruptcy court's order of sale. Even reversal on appeal of a sale order for property of a bankrupt's or debtor's estate does not affect a good faith purchaser's rights in the property unless a stay is entered pending appeal. See In re Highway Truck Drivers & Helpers Local Union # 107, 888 F.2d 293, 297 (3d Cir.1989). In such a case, the purchaser is protected even though he knows that an appeal of the order of sale is pending. See 11 U.S.C.A. § 363(m) (West 1979). I think the rights of a subsequent good faith purchaser without notice of an off-record agreement or misunderstanding should also be entitled to protection. "[After a sale t]he property may not be hauled back into the estate, and the terms of the sale are inviolate in the absence of fraud or collusion." In re Chicago, Rock Island & Pac. R.R. Co., 794 F.2d 1182, 1186 (7th Cir.1986). "Otherwise, anyone who could trace his title to a bankrupt could invoke [the bankruptcy court's] jurisdiction to settle disputes affecting that property." Xonics, 813 F.2d at 131.1 Accordingly, once the order of sale is final, I think the rights of subsequent good faith purchasers are determined under state law, in this case Pennsylvania's, in a state court. See generally Commonwealth, Pa. Game Comm'n v. Ulrich, 129 Pa.Cmwlth. 376, 565 A.2d 859, 861 (1989) (recording statutes intended to protect subsequent bona fide purchasers from secret or non-record agreements).

Accordingly, if the money owed Delaware County for taxes is secured by a lien, I do not think the bankruptcy court's later conflicting order can affect anyone who purchased in good faith reliance on the order's provision that the sale be free and clear of liens.

The lien and priority status of municipal tax claims in bankruptcy is not, however, a simple subject. Indeed, on the record before us, I cannot even tell whether the Delaware County tax lien was created pre- or post-petition. Conceivably, resolution of this question could eliminate the conflict between the orders in question since post-petition liens may run afoul of the automatic stay. See Makoroff v. City of Lockport, N.Y., 916 F.2d 890 (3d Cir.1990), cert. denied, --- U.S. ----, 111 S. Ct. 1640, 113 L. Ed. 2d 735 (1991). In Makoroff, we held that liens for city and county real property taxes that were created, not just perfected, post-petition violated the automatic stay because they constituted a property interest that the taxing authorities did not have at the time of the filing of the petition. Id. at 894. Liens, however, that attached pre-petition are valid in bankruptcy, see Equibank, N.A. v. Wheeling-Pittsburgh Steel Corp., 884 F.2d 80, 83 (3d Cir.1989), as are liens created pre-petition but perfected post-petition, Makoroff, 916 F.2d at 892. Equibank provides a general guide to the effect of a lien's status on the treatment of a debtor's property taxes:

The bankruptcy code permits tax liens to remain attached to secured property as of the date of the petition and entry of the stay. See 11 U.S.C. § 362. Where the liens are attached as of the date of the stay, the trustee has the power to sell the property free and clear of the liens by taking the liens out of the proceeds of sale. See 11 U.S.C. § 363(b). The code also provides two options for payment of taxes that have not attained lien status as of the date of the entry of the stay. First, they may be payable by the trustee, either as first priority administrative expenses, see 11 U.S.C. § 503(b)(1)(B)(i), or as seventh priority expenses, 11 U.S.C. § 507(a)(1). Second, they may be payable by the secured creditor as payment for benefit received, see 11 U.S.C. § 506(c).

Equibank, 884 F.2d at 83.

Whether the present objectors have the status of good faith purchasers or whether Delaware County has a lien for its taxes and, if it does, how it shall be provided for are, of course, matters not yet decided. Their resolution must await the consideration of the bankruptcy court on remand. If the facts, as they are developed, show that Delaware County has a lien for its taxes and that the objectors purchased the property in good faith reliance on the bankruptcy court's confirmed order of sale free and clear of all liens, I believe they would be entitled to have the provision in the final decree that requires the purchaser to pay Delaware County's tax lien set aside or at least modified pursuant to Rule 60(b)(6), to the extent necessary to the extent necessary to protect the rights under the sale.
