    Appeals from the United States District Court

    (February 20, 2015)
    Before HULL, JULIE CARNES, and WALKER,∗ Circuit Judges.
    HULL, Circuit Judge:
    ∗
    Honorable John Walker, Jr., United States Circuit Judge for the Second Circuit, sitting
    by designation.
    5
    Case: 12-15595       Date Filed: 02/20/2015       Page: 6 of 57
    These consolidated bankruptcy appeals arise out of a dispute between two
    competing groups—appellee the Redmond Group and appellant the Zeltser
    Group1—over ownership of, and control over, three involuntary debtors: Fisher
    Island Investments, Inc. (“Fisher Island”), Little Rest Twelve, Inc. (“Little Rest”),
    and Mutual Benefits Offshore Fund, Ltd. (“Mutual Benefits”) (collectively, the
    “Alleged Debtors”). 2 We refer to this dispute as the “ownership issue.”
    Litigation of the ownership issue in three bankruptcy cases has yielded five
    consolidated appeals of four orders: (1) the district court’s order denying the
    Zeltser Group’s motion to withdraw reference of the ownership issue; (2) the
    district court’s affirmance of the bankruptcy court’s summary judgment order in
    favor of the Redmond Group in the Fisher Island and Little Rest cases; (3) the
    district court’s order dismissing, for lack of standing, certain non-party appeals
    from the bankruptcy court’s summary judgment order; and (4) the district court’s
    affirmance of the bankruptcy court’s final judgment in favor of the Redmond
    Group in the Mutual Benefits case.
    1
    The groups are named after the lead attorneys representing them. The representatives of
    the Redmond Group include Patricia Redmond of Stearns Weaver Miller Weissler Alhadeff &
    Sitterson, P.A. and Martin Russo of Gusrae Kaplan & Nusbaum, PLLC. The Zeltser Group is
    represented by Emanuel Zeltser of Sternik & Zeltser and Darin DiBello of DiBello & Lopez,
    P.A.
    2
    Fisher Island is a Florida corporation that manages and owns developable property on
    Fisher Island, off the coast of Miami Beach in Florida. Little Rest is a New York corporation
    that owned and operated Ajna Bar (formerly Buddha Bar) in New York City. Mutual Benefits is
    a British Virgin Islands company formerly in the business of selling viatical insurance policies.

    Case: 12-15595     Date Filed: 02/20/2015     Page: 7 of 57
    After careful review of the record and the parties’ briefs, and with the
    benefit of oral argument, we affirm all orders on appeal.
    I. BACKGROUND
    These bankruptcy proceedings are but a small part of global litigation that
    began with the unexpected death of Arkadi (“Badri”) Patarkatsishvili in February
    2008. Badri was an extremely wealthy businessman and one-time presidential
    candidate from the Republic of Georgia. The resulting contest between two
    factions over the ownership and control of Badri’s assets, purportedly worth
    billions of dollars, has spawned litigation in the Republic of Georgia, the United
    Kingdom, Liechtenstein, the British territory of Gibraltar, and both state and
    federal courts in the United States. On one side of this protracted legal battle is the
    Redmond Group, consisting of Badri’s immediate family and led by Badri’s
    widow, Inna Gudavadze. The other side—the Zeltser Group—is led by Joseph
    Kay, Badri’s distant relative and former employee.
    Though complicated by “an ever-shifting labyrinth of corporations, trusts,
    partnerships, holding companies, and interested individuals,” the parties’
    competing positions on the ownership issue are essentially as follows. According
    to the Redmond Group, Fisher Island and Little Rest are owned by the Valmore
    Trust and Mutual Benefits is owned by the Test Trust—both Gibraltar trusts that
    were set up for the benefit of Badri and his family. According to the Zeltser
    7
    Case: 12-15595     Date Filed: 02/20/2015   Page: 8 of 57
    Group, Imedinvest Partners (“Imedinvest”), a partnership formed in the Republic
    of Georgia, owns Fisher Island, Little Rest, and Mutual Benefits.
    The dispute over ownership and control did not begin in the bankruptcy
    court. In a lawsuit filed by the then-trustee of the Valmore Trust, the Supreme
    Court of Gibraltar considered whether Badri or Kay was the beneficiary of the
    Valmore Trust. In 2009, after a nearly two-year proceeding, the Gibraltar Court
    concluded that the vast majority of the assets in the Valmore Trust were funded by
    Badri and held for the benefit of Badri’s immediate family. After Kay abandoned
    his appeal of that judgment, the Gibraltar Court declared that Kay had no interest
    in the assets of the Valmore Trust, which belonged solely to Badri. The Gibraltar
    Court’s decision entailed an implicit finding that the Valmore Trust was valid.
    Before the filing of the involuntary petitions in March 2011, the Zeltser
    Group advanced its theory of ownership in state courts in New York and Florida.
    In the New York action, attorney Emanuel Zeltser claimed, on behalf of
    Imedinvest and Joseph Kay, that the Valmore Trust was a “sham” and that
    Imedinvest, of which Kay was allegedly the managing partner, was the owner of
    Little Rest. On July 22, 2011, the New York court issued a decision rejecting the
    sham trust argument on multiple grounds, determining that Zeltser had no authority
    to represent Little Rest, and substituting attorneys for the Redmond Group as
    counsel for Little Rest. See Little Rest Twelve, Inc. v. Visan, No. 600676/2007
    8
    Case: 12-15595   Date Filed: 02/20/2015   Page: 9 of 57
    (N.Y. Sup. Ct. N.Y. Cnty. July 22, 2011) (order substituting counsel). Similarly,
    attorney Darin DiBello represented Kay in litigating the ownership and
    representation of Fisher Island in the Florida action. See Motion to Strike
    Complaint, Fisher Island Invs., Inc. v. Baker, No. 10-14866 (11th Jud. Cir. of
    Miami-Dade Cnty., Fla. Mar. 15, 2010).
    II. BANKRUPTCY COURT PROCEEDINGS
    A.     Involuntary Petitions
    On March 17, 2011, a group of six individuals and entities—
    Solby+Westbrae Partners; 19 SHC, Corp.; Ajna Brands, Inc.; 601/1700 NBC,
    LLC; Axafina, Inc.; and Oxana Adler (collectively, the “Petitioning Creditors”)—
    filed three separate involuntary Chapter 11 bankruptcy petitions in the U.S.
    Bankruptcy Court for the Southern District of Florida against Fisher Island, Little
    Rest, and Mutual Benefits. The involuntary petitions were filed as the parties
    anticipated key rulings on the ownership issue in the New York and Florida
    litigations.
    The involuntary petitions asserted claims against the Alleged Debtors for
    approximately $32.4 million, $28.5 million of which was based on a promissory
    note (the “Note”) purportedly executed by the Alleged Debtors and assigned to
    three of the Petitioning Creditors by a non-party, Areal Plus Group. The
    Petitioning Creditors, asserting that the Alleged Debtors were “affiliates,” moved
    9
    Case: 12-15595        Date Filed: 02/20/2015   Page: 10 of 57
    the bankruptcy court to jointly administer the three cases and to appoint a trustee to
    take control and possession of the Alleged Debtors’ assets.
    B.    Ownership Issue
    Two sets of attorneys—representing the Zeltser Group and the Redmond
    Group, respectively—entered appearances of record in the bankruptcy court, both
    purporting to act on behalf of the Alleged Debtors. On March 21, 2011, four days
    after the involuntary petitions were filed, the Zeltser Group, through attorney
    DiBello, filed answers on behalf of the Alleged Debtors, immediately admitting to
    the allegations in the involuntary petitions against the Alleged Debtors and
    consenting to the relief requested by the Petitioning Creditors.
    The next day, the Redmond Group, through attorney Redmond, filed an
    emergency motion to strike the Zeltser Group’s answers. The Redmond Group,
    claiming to be the actual authorized representatives of the Alleged Debtors, alleged
    that the involuntary petitions were improperly filed in an attempt to stay the state
    court litigation in Florida and New York. To adjudicate the underlying debt, the
    bankruptcy court had to decide who owned the Alleged Debtors, and thus who had
    the authority to retain counsel.
    In response to the motion to strike, the Zeltser Group asked the bankruptcy
    court to deny the relief sought therein until resolving the question of who had the
    authority to act on behalf of the Alleged Debtors. Notably, the Zeltser Group
    10
    Case: 12-15595    Date Filed: 02/20/2015   Page: 11 of 57
    stated in its response that “the issues of proper ownership and control over the
    Alleged Debtor[s] should be litigated in due course before this Court.”
    Faced with these contradictory claims, the bankruptcy court held a hearing
    on March 25, 2011. The bankruptcy court noted that it was highly unusual that the
    Alleged Debtors, as represented by the Zeltser Group, immediately consented to
    the involuntary petitions. As to the ownership issue, attorney Zeltser contended
    that Imedinvest, a “loose investment partnership” owned all three of the Alleged
    Debtors. According to Zeltser, Badri had been a partner of Imedinvest, and it was
    on behalf of Imedinvest and other entities that the Note debt had been incurred.
    Counsel for the Redmond Group denied that Imedinvest had any ownership
    interest in the Alleged Debtors. Instead, the Redmond Group asserted that the
    Valmore Trust ultimately owned Fisher Island and Little Rest through its trustee,
    Miselva Establissement (“Miselva”). The Redmond Group also asserted that
    Mutual Benefits was comprised of several investors, the largest of which was
    Kayley Investments, N.V. (“Kayley”). In turn, Kayley was legally owned by the
    Test Trust.
    During the hearing, the Zeltser Group specifically requested that the
    bankruptcy court decide the ownership issue. Attorney Zeltser claimed that the
    New York and Florida state courts could not determine ownership, and informed
    the bankruptcy court that it, as the “ultimate Court of equity,” was the “only court”
    11
    Case: 12-15595       Date Filed: 02/20/2015        Page: 12 of 57
    that could resolve the issue. Furthermore, the bankruptcy court’s decision on the
    issue, presumably after a short “ownership hearing,” would be “dispositive.”
    The Redmond Group later filed answers and motions to dismiss on behalf of
    the Alleged Debtors, denying the allegations in the involuntary petitions, raising
    affirmative defenses, and seeking dismissal of the petitions as filed in bad faith.
    Thus, whether the petitions were contested depended on a threshold determination
    of which group was authorized to represent the Alleged Debtors in the
    proceedings.
    C.     Discovery and Examiner’s Report
    On March 31, 2011, the bankruptcy court granted in part the Petitioning
    Creditors’ motion to jointly administer the three cases. Although the bankruptcy
    court doubted how the “three widely disparate business operations” were affiliates,
    it granted the motion “for the sole purpose of conducting one trial regarding the
    validity of the . . . Note, the assignment of the Note and determination of who are
    the legitimate representatives and attorneys for the three alleged involuntary
    debtors.” The bankruptcy court also appointed a Chapter 11 Examiner to
    investigate the ownership issue, among other things.3
    3
    The bankruptcy court remarked that the involuntary petitions raised a smell, pointing to
    irregularities such as the timing of the involuntary petitions in relation to the state court
    litigation, the timing of the answers consenting to the relief sought in the petitions, the
    questionable authenticity of the Note, and the highly unusual situation of two groups vying to
    represent alleged debtors.
    12
    Case: 12-15595    Date Filed: 02/20/2015    Page: 13 of 57
    At the bankruptcy court’s direction, the parties conferred regarding
    discovery and pre-trial procedures and agreed to a case management order. On
    June 7, 2011, the bankruptcy court issued the agreed “Case Management and
    Schedule Order in Contested Matter Setting Filing and Disclosure Requirements
    for Pre-Trial and Trial” (the “Schedule Order”) (emphasis added). Notably, the
    Schedule Order provided for extensive discovery, including mandatory disclosures
    of witnesses and documents, interrogatories, requests for admission, document
    requests, depositions, and expert reports. The Schedule Order directed the parties
    to submit findings of fact rather than jury instructions, and noted that the
    bankruptcy court would set a trial date for “this contested matter” at the pre-trial
    conference.
    On November 18, 2011, the Examiner issued a 96-page report addressing the
    ownership of the Alleged Debtors and the claims of the Petitioning Creditors. The
    Examiner found that the Valmore Trust was the ultimate owner of both Fisher
    Island and Little Rest. As to Mutual Benefits, the Examiner found that Kayley was
    ultimately owned by the Test Trust. Accordingly, the attorneys for the Redmond
    Group (not the Zeltser Group) were authorized to represent the Alleged Debtors.
    The Examiner explained that the ownership dispute with respect to Mutual
    Benefits was different from Fisher Island and Little Rest in that Mutual Benefits
    was never held within the Valmore Trust. The Examiner’s review indicated that
    13
    Case: 12-15595    Date Filed: 02/20/2015   Page: 14 of 57
    W. Shaun Davis, through his management company, Triangle International
    Management Limited (“Triangle”), owned 100% of Mutual Benefits’ voting
    shares. All of Mutual Benefits’ other shareholders, including Kayley, held non-
    voting shares. Mutual Benefits was therefore controlled by its voting shareholder,
    Triangle.
    The Examiner generally found the Zeltser Group’s story with respect to
    ownership to be inconsistent and irreconcilable with, or unsupported by, the
    record. For instance, the Zeltser Group provided little extrinsic evidence to prove
    the existence of Imedinvest. In fact, Joseph Kay and his sister testified in
    connection with the Gibraltar proceeding in 2009 that they were unfamiliar with
    Imedinvest. The Examiner also determined that the Zeltser Group had submitted
    certain documentation in “an intentional effort to mislead or misrepresent material
    facts to a court.”
    After several months of extensive discovery in accordance with the Schedule
    Order (as well as extensions), which produced more than 200,000 pages of
    documents, the record was closed on November 30, 2011.
    D.    Summary Judgment in Fisher Island and Little Rest Cases
    1.     Motion for Partial Summary Judgment
    Notwithstanding the Examiner’s unfavorable report, on November 21, 2011,
    the Zeltser Group moved for partial summary judgment on the ownership issue in
    14
    Case: 12-15595        Date Filed: 02/20/2015       Page: 15 of 57
    the Fisher Island and Little Rest cases.4 The Zeltser Group sought a determination
    that: (1) the Valmore Trust was invalid; (2) neither Gibraltar law nor United
    Kingdom law applied to the proceedings; and (3) JWL Entertainment Group, Inc.
    (“JWL”), a Delaware corporation, was the equitable owner of Fisher Island and
    Little Rest.
    The Zeltser Group’s ownership theory was twofold. First, the Valmore
    Trust 5 was a “sham” and invalid because Kay, and not Badri, was the settlor and
    beneficiary. Alternatively, Fisher Island Limited (“Fisher Limited”) and
    Grosvenor Trading Holding Limited (“Grosvenor”), which the Zeltser Group
    acknowledged were the respective parent companies of Fisher Island and Little
    Rest, were transferred from trustee Miselva to JWL. JWL was then transferred out
    of the Valmore Trust to Imedinvest. The Zeltser Group argued that, pursuant to
    these transactions, JWL held equitable ownership of Fisher Island and Little Rest.
    Paradoxically, the Zeltser Group maintained that the bankruptcy court lacked
    jurisdiction to resolve any issue regarding the JWL transactions.
    In opposition to the partial summary judgment motion, the Redmond Group
    argued that the Gibraltar Court’s judgment precluded the bankruptcy court from
    4
    As discussed below, see infra Part III.A, the Zeltser Group also moved to withdraw
    reference of the bankruptcy proceedings to the district court for adjudication of the ownership
    issue.
    5
    In the motion, the Zeltser Group acknowledged the Redmond Group’s assertion that SP
    Trustees Gmbh (“SP Trustees”) was the successor to Miselva, the then-trustee of the Valmore
    Trust.
    15
    Case: 12-15595    Date Filed: 02/20/2015   Page: 16 of 57
    determining the validity of the Valmore Trust. The Gibraltar Court’s factual
    findings, including its implicit finding that the Valmore Trust was valid, were
    entitled to comity, and a New York state court specifically declined to find that the
    Valmore Trust was a sham. Furthermore, the JWL transaction was abandoned.
    Even assuming the transaction was completed, Miselva was still the legal and
    beneficial owner of Fisher Limited and Grosvenor, as indicated in an unrebutted
    expert opinion submitted by the Redmond Group. The Zeltser Group did not file a
    reply.
    2.    Motion for Clarification/Reconsideration
    On November 30, 2011, the Zeltser Group filed a motion for clarification
    and/or reconsideration of the June 7, 2011 Schedule Order. The Zeltser Group
    argued, for the first time in the proceedings, that the bankruptcy court could not
    adjudicate the ownership issue (1) without joinder of all indispensable parties, and
    (2) without violating due process because the ownership issue was raised as a
    contested matter in the Redmond Group’s motion to strike rather than as an
    adversary proceeding. The motion listed a string of individuals and entities that
    were allegedly involved in the ownership chain and therefore “indispensable,”
    including the Valmore Trust, Miselva, JWL, Fisher Limited, Grosvenor, Badri’s
    widow, and Imedinvest.
    16
    Case: 12-15595    Date Filed: 02/20/2015   Page: 17 of 57
    The bankruptcy court denied the motion for clarification/reconsideration,
    finding that any objection should have been raised contemporaneously with entry
    of the agreed-upon Schedule Order, not several months after-the-fact.
    3.    Denial of Partial Summary Judgment
    On December 29, 2011, the bankruptcy court denied the Zeltser Group’s
    motion for partial summary judgment. In the “Procedural History” section of the
    order, the bankruptcy court discussed the appointment of the Examiner and the
    production of the Examiner’s report. The bankruptcy court then set forth the
    material facts concerning the formation and operation of the Valmore Trust, as
    well as the Gibraltar and New York litigations. The “Material Facts” section made
    no mention of the Examiner or his report. Based on these material facts, the
    bankruptcy court rejected the argument that the Valmore Trust was a sham and
    declined to reverse any findings made by the Gibraltar Court. Furthermore, the
    bankruptcy court determined that the JWL transaction was abandoned and that
    pursuant to the unrebutted expert opinion submitted by the Redmond Group,
    neither legal nor beneficial ownership of Fisher Limited or Grosvenor passed to
    JWL.
    The bankruptcy court stated that, pursuant to Federal Rule of Bankruptcy
    Procedure 7056(f), it was “inclined to determine as a matter of law” that Miselva
    (then trustee of the Valmore Trust) owned Fisher Limited and Grosvenor. The
    17
    Case: 12-15595    Date Filed: 02/20/2015   Page: 18 of 57
    parties did not dispute that Fisher Limited owned Fisher Island and Grosvenor
    owned Little Rest. Thus, the bankruptcy court was in effect notifying the parties
    that it intended to rule that the Valmore Trust owned Alleged Debtors Fisher Island
    and Little Rest. Nevertheless, the bankruptcy court gave the Zeltser Group an
    additional 21 days to file a legal memorandum, “based on the existing record,” to
    persuade the court not to enter summary judgment as indicated.
    Despite this invitation by the bankruptcy court, the Zeltser Group declined to
    file any additional memorandum addressing the ownership issue. Instead, the
    Zeltser Group objected to the “confines imposed” with respect to the permitted
    memorandum and advised the bankruptcy court that it would “rely on the existing
    record.” The Zeltser Group did not explain what additional discovery it believed
    was necessary or what it would prove if given the opportunity to expand the
    record.
    During a hearing on January 5, 2012, the bankruptcy court granted the
    Redmond Group’s oral motion to prepare a proposed memorandum opinion
    regarding the entry of summary judgment and instructed both the Redmond Group
    and the Zeltser Group to do so within five days. The Petitioning Creditors (joined
    by the Zeltser Group) moved for reconsideration of this ruling, arguing that the
    Redmond Group intended to include in its proposed opinion new findings and
    18
    Case: 12-15595     Date Filed: 02/20/2015   Page: 19 of 57
    conclusions not present in the bankruptcy court’s December 29, 2011 denial of
    partial summary judgment.
    On January 10, 2012, the bankruptcy court denied the Petitioning Creditors’
    motion for reconsideration as without merit. The bankruptcy court stated that it
    had no intention of entering an order that supplemented the record. Summary
    judgment would not be entered on allegedly “new or different” grounds but “rather
    on the very same undisputed facts and legal grounds” on which the bankruptcy
    court denied the Zeltser Group’s motion for partial summary judgment.
    4.     Bankruptcy Court’s Summary Judgment Order
    On January 20, 2012, the bankruptcy court, sua sponte, entered an order
    granting summary judgment in favor of the Redmond Group in the Fisher Island
    and Little Rest cases, as the court had indicated it was inclined to do. The
    bankruptcy court noted that, despite being given the opportunity to do so, the
    Zeltser Group chose not to raise any issues of disputed fact or otherwise point to
    specific record evidence potentially raising a disputed factual issue. The
    bankruptcy court also noted that SP Trustees had replaced Miselva as trustee of the
    Valmore Trust.
    After reviewing the record and drawing all reasonable inferences in favor of
    the Zeltser Group, the bankruptcy court found, as a matter of law, that Fisher
    Limited, Grosvenor, and their respective subsidiaries (including Fisher Island and
    19
    Case: 12-15595       Date Filed: 02/20/2015      Page: 20 of 57
    Little Rest) were assets of the Valmore Trust. Final summary judgment was
    entered as follows: the Valmore Trust, through its trustee (currently SP Trustees)
    owned (1) 100% of Fisher Limited, which (through an intermediary) owned 100%
    of Fisher Island, and (2) 100% of Grosvenor, which owned 85% of Little Rest,
    with the remaining 15% of Little Rest owned by an individual not directly involved
    in the ownership dispute.
    Three groups appealed the bankruptcy court’s January 20, 2012 summary
    judgment order to the district court: (1) the Zeltser Group (still purporting to
    represent Fisher Island and Little Rest), (2) the Petitioning Creditors, and (3) five
    non-party entities affiliated with the Zeltser Group, including Fisher Limited,
    Grosvenor, and Areal Group (“Areal”) 6 (collectively, the “non-party appellants”).
    These appeals were consolidated by U.S. District Court Judge Kathleen Williams.
    E.     Trial in Mutual Benefits Case
    1.     Denial of Summary Judgment
    On February 13, 2012, the Redmond Group moved for summary judgment
    on the ownership issue in the Mutual Benefits case. The Redmond Group sought a
    determination that Mutual Benefits was owned by 24 investors, and that the Test
    Trust was the ultimate owner of Kayley, the largest investor of Mutual Benefits.
    The Zeltser Group responded, inter alia, that the bankruptcy court lacked authority
    6
    Areal is apparently a wholly owned subsidiary of Areal Plus Group, the assignor of the
    Note, as well as a creditor and former partner of Imedinvest.
    20
    Case: 12-15595       Date Filed: 02/20/2015       Page: 21 of 57
    to make a final determination as to ownership, and could not make any such
    determination without joinder of all the alleged owners of Mutual Benefits (i.e., the
    investors).
    On August 28, 2012, the bankruptcy court denied the Redmond Group’s
    motion, finding that genuine issues of material fact raised by the Zeltser Group’s
    response precluded summary judgment. The bankruptcy court subsequently set the
    matter for a two-day bench trial, to begin on April 11, 2013—over two years after
    the case was filed.
    2.      Pre-Trial and Motion for Continuance
    In October 2012, the parties filed their lists of intended witnesses and
    exhibits. The Zeltser Group named 36 witnesses it intended to call at trial as part
    of its case-in-chief, including Galina Orlowskaya, Natasha Bransburg, and
    Petitioning Creditor Oxana Adler, 7 and identified hundreds of exhibits. The
    bankruptcy court ordered the parties to submit sworn declarations of their intended
    witnesses’ direct testimony at least 10 days before trial. In response, the Redmond
    Group filed the declaration of W. Shaun Davis, the president and sole director of
    Mutual Benefits. The Zeltser Group filed the declaration of Oxana Adler.
    7
    Adler, who is apparently an attorney licensed in Russia, told the Examiner that she has
    represented Imedinvest and its affiliates (including Badri and the Alleged Debtors) for more than
    14 years. The claims she asserted in the involuntary petitions arose out of legal services
    allegedly provided to the Alleged Debtors.
    21
    Case: 12-15595        Date Filed: 02/20/2015       Page: 22 of 57
    On April 1, 2013, the Zeltser Group filed a motion for an extension of time
    to file the direct testimony declarations of Orlowskaya and Bransburg and for a 60-
    day continuance of the trial. According to the Zeltser Group, Orlowskaya and
    Bransburg did not want to give their testimony at that time because they were
    concerned for their personal safety in light of the March 23, 2013 death of Russian
    businessman Boris Berezovsky. The motion did not specify any connection
    between the witnesses and Berezovsky, or otherwise explain the relevance of his
    death to the Mutual Benefits bankruptcy proceeding. 8 The bankruptcy court
    denied the motion for continuance.
    3.      Trial
    Trial began as scheduled on April 11, 2013. The Redmond Group called
    Davis to testify in person and through his previously filed declaration. Davis
    testified as follows. He was the owner of Meridian Asset Management Ltd., which
    owned 99% of Triangle, which in turn owned all of the voting shares in Mutual
    Benefits. Davis was appointed as the president and sole director of Mutual
    Benefits in 2002 and continues to serve in that capacity. Kayley and 22 other
    8
    The Zeltser Group later submitted sworn declarations by Orlowskaya, Bransburg, and
    Adler, which stated that they had received threats of bodily harm from individuals associated
    with the Redmond Group. Adler vaguely declared that she believed Berezovsky’s death to be
    “intrinsically connected to his claims to assets [at issue] in the proceedings.” According to the
    Zeltser Group’s appellate briefs in this Court, Berezovsky is associated with Badri’s widow,
    Gudavadze.
    22
    Case: 12-15595   Date Filed: 02/20/2015   Page: 23 of 57
    investors held non-voting shares in Mutual Benefits, which only entitled them to an
    economic interest in the profits and did not confer any voting power.
    Davis testified that he retained the Redmond Group attorneys in the
    bankruptcy case and that the Zeltser Group attorneys were not authorized to
    represent Mutual Benefits. Davis’s testimony was corroborated by various
    exhibits, many of which were admitted into evidence without objection.
    Attorney Zeltser then cross-examined Davis for four hours. Zeltser
    attempted to establish that Mutual Benefits defrauded its investors and that Davis
    was merely a “nominee” without any decision making power. Davis denied both
    propositions.
    At the close of the Redmond Group’s case-in-chief, the Zeltser Group orally
    moved for judgment on partial findings under Federal Rule of Civil Procedure
    52(c) and for involuntary dismissal under Federal Rule of Civil Procedure 41(b).
    The Zeltser Group argued that the Redmond Group failed to meet its burden of
    establishing who owned Mutual Benefits based on Davis’s testimony—the sole
    evidence presented by the Redmond Group. The bankruptcy court found that the
    Redmond Group had presented a prima facie case and denied both motions. In
    doing so, the bankruptcy court reasoned that “a motion on Rule 52(c) or Rule 41 is
    in some way similar to a summary judgment motion; that is, it is not a time for
    23
    Case: 12-15595     Date Filed: 02/20/2015    Page: 24 of 57
    making credibility choices. It is a time to determine whether there is evidence, if
    accepted, that . . . can constitute a prima facie case.”
    The Zeltser Group also renewed its motion for a continuance of the trial,
    citing the unavailability of Orlowskaya, Bransburg, and Adler. The bankruptcy
    court ruled that Orlowskaya and Bransburg would be allowed to testify at a
    continued trial date on April 27, 2013, if they were produced for depositions by
    April 18, 2013. However, the bankruptcy court refused to extend this limited
    continuance to Adler. The bankruptcy court stated that Adler’s extensive
    involvement in the case was a matter of public record and declined to give Adler
    “any further consideration” if “she chose not to be here today.”
    The bankruptcy court ordered the Zeltser Group to proceed with its case-in-
    chief. Despite having submitted exhaustive lists of witnesses and exhibits, the
    Zeltser Group did not call any witnesses or offer any exhibits at trial. Instead,
    attorney DiBello informed the bankruptcy court that the Zeltser Group had nothing
    to present except for the testimony of Orlowskaya, Bransburg, and Adler. Because
    Orlowskaya and Bransburg did not appear for deposition by April 18, 2013, they
    were barred from testifying at all. The trial record was closed without any
    evidence proffered by the Zeltser Group.

    Case: 12-15595    Date Filed: 02/20/2015      Page: 25 of 57
    4.     Bankruptcy Court’s Final Judgment
    On April 25, 2013, the bankruptcy court entered its findings of fact and
    conclusions of law in favor of the Redmond Group. The court found the Redmond
    Group’s testimonial and documentary evidence to be credible and persuasive,
    whereas the Zeltser Group failed to submit any evidence to support an alternative
    theory of ownership.
    The bankruptcy court found that Triangle owned the controlling “Managers
    Shares” of Mutual Benefits. As the controlling shareholder, Triangle appointed
    Davis as president and sole director of Mutual Benefits. Davis had the exclusive
    authority to retain counsel to represent Mutual Benefits, and, pursuant to that
    authority, Davis retained the Redmond Group’s attorneys in the involuntary
    bankruptcy proceeding. Accordingly, the bankruptcy court granted the Redmond
    Group’s motion to strike the Zeltser Group’s answer and set the Redmond Group’s
    motion to dismiss the involuntary petition for a hearing.
    Pursuant to its findings of fact and conclusions of law, the bankruptcy court
    entered a separate final judgment in favor of the Redmond Group. The final
    judgment determined that the Zeltser Group was not authorized to represent
    Mutual Benefits in the bankruptcy proceeding. The Zeltser Group (still purporting
    to represent Mutual Benefits) timely appealed the April 25, 2013 final judgment to
    the district court.
    25
    Case: 12-15595     Date Filed: 02/20/2015   Page: 26 of 57
    On appeal, the district court granted the Redmond Group’s motion for leave
    to supplement the record, which attached deposition testimony from Bransburg in
    which she admitted that she did not know anything about Mutual Benefits and that
    she never had any relevant testimony to give at trial.
    III. DISTRICT COURT PROCEEDINGS
    A.    District Court’s Denial of Motion to Withdraw Reference of Ownership
    Issue
    On November 30, 2011, the Zeltser Group moved to withdraw reference of
    the ownership issue, pursuant to 28 U.S.C. § 157(d), in each bankruptcy case.
    Remarkably, the motion to withdraw reference was filed on the same day as the
    Zeltser Group’s motion for clarification and/or reconsideration of the bankruptcy
    court’s Schedule Order, within two weeks of the unfavorable Examiner’s report
    and the Zeltser Group’s partial summary judgment motion filed in the Fisher Island
    and Little Rest cases, and five months after the Supreme Court’s June 23, 2011
    decision in Stern v. Marshall, 564 U.S. __, 
    131 S. Ct. 2594
    (2011).
    Notwithstanding its earlier conduct and express representations before the
    bankruptcy court, the Zeltser Group now objected to the bankruptcy court’s
    adjudication of ownership. According to the Zeltser Group, the bankruptcy court
    lacked authority to enter a final determination on the ownership issue under Stern.
    The Zeltser Group pointed to the distinction between core bankruptcy proceedings,
    which either “arise under” title 11 (the Bankruptcy Code) or “arise in” a case under
    26
    Case: 12-15595    Date Filed: 02/20/2015    Page: 27 of 57
    title 11, and non-core proceedings to support its jurisdictional argument. Because
    the district court has the exclusive authority to decide the ownership issue, the
    Zeltser Group requested that the reference to the bankruptcy court be withdrawn to
    the extent the bankruptcy court was going to rule on the issue as a contested
    matter.
    The district court held two hearings on the Zeltser Group’s motion to
    withdraw reference. During the first hearing, the Zeltser Group denied that the
    ownership issue was a core matter. During the second hearing, however, the
    Zeltser Group acknowledged that the ownership issue was “core” and that it had
    originally consented to a trial in the bankruptcy court before the Stern decision.
    Nonetheless, the Zeltser Group argued that it was entitled to a trial in an Article III
    court as a result of Stern.
    On January 31, 2012, U.S. District Court Judge Paul Huck issued a
    consolidated order denying the Zeltser Group’s motion to withdraw reference,
    which he characterized as a “belated change of heart.” District Court Judge Huck
    found that the ownership issue fell within the bankruptcy court’s core jurisdiction
    as a proceeding “arising under title 11, or arising in a case under title 11,” and the
    Stern decision had no impact on the bankruptcy court’s authority. Unlike the state
    law counterclaim at issue in Stern, the ownership issue was “deeply embedded” in
    the case. The bankruptcy court was “necessarily required to determine who the
    27
    Case: 12-15595       Date Filed: 02/20/2015       Page: 28 of 57
    real owners of the Alleged Debtors actually [were] in order to rule on the creditors’
    claims.” Even assuming the relevance of Stern, the Zeltser Group “explicitly,
    unquestioningly, and expressly consented to a non-jury trial” in the bankruptcy
    court on the ownership issue and clearly waived any right it may have had to a trial
    before an Article III judge.
    B.     District Court’s Affirmance of Summary Judgment in Fisher Island and
    Little Rest Cases
    On October 16, 2013, District Court Judge Williams affirmed the
    bankruptcy court’s January 20, 2012 summary judgment order in favor of the
    Redmond Group. As an initial matter, District Court Judge Williams concluded
    that the Zeltser Group waived many of the issues on appeal by failing to raise them
    in response to the bankruptcy court’s invitation to submit legal briefing on its
    intended summary judgment order. 9
    First, District Court Judge Williams rejected the Zeltser Group’s argument
    that it lacked sufficient notice of the summary judgment order. She concluded that
    the bankruptcy court’s December 29, 2011 denial of the Zeltser Group’s partial
    summary judgment motion gave the Zeltser Group more than adequate notice of
    the bankruptcy court’s intention to enter summary judgment on the ownership of
    9
    District Court Judge Williams stated that the Zeltser Group’s “refusal to raise these
    arguments in the time and manner ordered by the Bankruptcy Court did, in fact, constitute a
    waiver, which cannot be avoided by [the Zeltser Group] asserting that they do not want it to be a
    waiver.”
    28
    Case: 12-15595     Date Filed: 02/20/2015    Page: 29 of 57
    Fisher Island and Little Rest, as well as 21 days to submit further briefing on the
    issue.
    Second, the district court concluded there were no procedural defects in the
    entry of summary judgment because the parties had a full and fair opportunity to
    develop the (ample) record, and the Zeltser Group never indicated that further
    discovery was needed. Third, the district court concluded that even assuming
    arguendo that the Zeltser Group did not waive the issue, the bankruptcy court did
    not improperly rely on the Examiner’s report, which was not mentioned anywhere
    in the summary judgment order. Fourth, the district court found that the Zeltser
    Group waived its argument concerning joinder. In any event, the district court
    concluded, the bankruptcy court did not err in deciding the threshold ownership
    issue in the absence of asserted “indispensable” parties.
    Fifth, the district court concluded, again assuming that the Zeltser Group did
    not waive the issue, that the bankruptcy court did not err in allowing the ownership
    issue to proceed as a contested matter rather than as an adversary proceeding.
    Even if the bankruptcy court erred, the district court reasoned, the Zeltser Group
    invited the error by encouraging the bankruptcy court to determine the ownership
    issue and litigating the issue as a contested matter for months before finally
    objecting. Sixth, the district court held that because there were no genuine disputes
    of material fact as to whether the Valmore Trust owned Fisher Island and Little
    29
    Case: 12-15595     Date Filed: 02/20/2015   Page: 30 of 57
    Rest, the bankruptcy court properly granted summary judgment based on the
    record.
    The Zeltser Group, purportedly on behalf of Fisher Island and Little Rest,
    timely appealed District Court Judge Williams’s October 16, 2013 order to this
    Court.
    C.       District Court’s Dismissal of Appeals by Non-Party Appellants
    The Redmond Group moved to dismiss the Petitioning Creditors’ and the
    non-party appellants’ appeals for lack of standing to challenge the bankruptcy
    court’s January 20, 2012 summary judgment order.
    Relevant to these appeals, non-party appellants Fisher Limited and
    Grosvenor responded that they were aggrieved by the bankruptcy court’s summary
    judgment order, which “awarded” their ownership interests to SP Trustees and
    “eviscerated” their property rights. The four exhibits attached to their response
    consisted entirely of pleadings from the New York state case involving the
    ownership of Little Rest.
    Non-party appellant Areal, represented by the same attorney who filed the
    involuntary petitions on behalf of the Petitioning Creditors, also filed a
    memorandum and exhibit in response. To show the existence of a pecuniary
    interest sufficient to confer standing, Areal relied solely on a March 24, 2004
    pledge agreement in which it purportedly invested $12 million in Little Rest. The
    30
    Case: 12-15595   Date Filed: 02/20/2015   Page: 31 of 57
    pledge agreement referred to other documents that were not submitted by Areal in
    its response.
    The Redmond Group filed a reply brief on June 11, 2012, challenging the
    authenticity and legitimacy of Areal’s sole exhibit. The Redmond Group
    submitted reports by two forensic handwriting experts who opined that the
    signatures on the pledge agreement were not “independent creations” but rather
    were transferred from another source. The Redmond Group also submitted a
    sworn declaration from Little Rest’s financial controller, who stated that he had
    never seen the agreement before and that it was not kept in the course of ordinary
    business. Areal did not seek leave to file a sur-reply brief or request an evidentiary
    hearing.
    On October 23, 2012, District Court Judge Williams granted the Redmond
    Group’s motions to dismiss and dismissed all appellants of the bankruptcy court’s
    January 20, 2012 summary judgment order except for the Zeltser Group.
    District Court Judge Williams found that Areal failed to satisfy the two
    prerequisites for standing to appeal. First, Areal was not aggrieved by the
    summary judgment order under the “person aggrieved” doctrine applicable to
    bankruptcy appeals. Areal did not submit any affidavits or declarations
    authenticating the pledge agreement, which was neither witnessed nor notarized
    and did not appear to be a standard legal document. The district court noted that
    31
    Case: 12-15595     Date Filed: 02/20/2015   Page: 32 of 57
    the pledge agreement bore an upside down corporate seal, which also indicated
    digital manipulation. Furthermore, the agreement provided only that Areal
    “contemplates” investing $12 million in Little Rest—Areal did not offer any
    evidence that the funds were actually transferred. On the other hand, the Redmond
    Group submitted two forensic reports and a sworn declaration to rebut the
    authenticity of the pledge agreement. Accordingly, the district court concluded
    that the only document on which Areal relied had not been sufficiently
    authenticated.
    Second, the district court concluded that although Areal was given proper
    notice of the bankruptcy proceedings, it failed to appear and object to the entry of
    summary judgment in the bankruptcy court. Similarly, the district court held that
    Fisher Limited and Grosvenor lacked standing because they failed to appear and
    object to the entry of summary judgment in the bankruptcy court, despite their
    attorneys having actual notice of the bankruptcy proceedings from the outset.
    District Court Judge Williams rejected the non-party appellants’ argument
    that their failure to attend or object should be excused because they did not receive
    “proper” notice of the bankruptcy proceedings due to the Redmond Group’s failure
    to initiate the requisite adversary proceeding. District Court Judge Williams found
    that this argument was not properly preserved, and that the Redmond Group was
    not required to file an adversary proceeding to raise the ownership issue instead of
    32
    Case: 12-15595      Date Filed: 02/20/2015    Page: 33 of 57
    the Redmond Group’s motion to strike the Zeltser Group’s answers to the
    involuntary petitions. Even assuming there was such a requirement, the district
    court concluded that the Redmond Group’s failure to do so would not excuse the
    non-party appellants’ decision to deliberately wait to appear and object until after
    entry of the bankruptcy court’s adverse summary judgment order. To conclude
    otherwise “would not only encourage litigation by ambush, but it would reward
    conduct that . . . is, at best, an attempt to game the system and, at worst, a
    coordinated effort to perpetrate a fraud on this Court.”
    At this point, in the district court, the only remaining parties were the Zeltser
    Group, as appellant, and the Redmond Group, as appellee, of the bankruptcy
    court’s January 20, 2012 order on the ownership of Fisher Island and Little Rest.
    The non-party appellants timely appealed District Court Judge Williams’s October
    23, 2012 dismissal of their bankruptcy appeals to this Court.
    D.    District Court’s Affirmance of Final Judgment in Mutual Benefits Case
    On March 19, 2014, U.S. District Court Judge K. Michael Moore affirmed
    the bankruptcy court’s April 25, 2013 judgment in favor of the Redmond Group.
    The district court reached the following conclusions. First, the bankruptcy
    court had jurisdiction and authority to enter final judgment on the ownership issue.
    District Court Judge Moore agreed with District Court Judge Huck’s finding that
    the ownership issue, which had to be resolved before the bankruptcy court could
    33
    Case: 12-15595      Date Filed: 02/20/2015   Page: 34 of 57
    adjudicate the underlying debt, clearly “arises under” or “arises in” a case under
    Chapter 11. Second, the bankruptcy court had all necessary parties before it to
    enter final judgment on the ownership issue as to the named Alleged Debtors.
    Even if mandatory joinder applied in contested matters, the Zeltser Group failed to
    meet its burden that the non-parties were both necessary and indispensable.
    Third, the bankruptcy court did not err in allowing the ownership issue to
    proceed as a contested matter raised in the Redmond Group’s motion to strike the
    Zeltser Group’s answers to the involuntary petitions, rather than proceeding as a
    separate adversary proceeding. Fourth, the bankruptcy court did not abuse its
    discretion in denying the Zeltser Group’s motion for a continuance. The Zeltser
    Group did not act diligently in preparing for trial, and there was no reason to
    believe that granting the continuance would have remedied the asserted reason for
    the witnesses’ unavailability.
    Fifth, the bankruptcy court’s final judgment was not clearly erroneous. The
    evidence at trial established that Triangle owned all of Mutual Benefits’ voting
    shares, and that Davis, as the president and sole director of both Triangle and
    Mutual Benefits, retained the Redmond Group’s attorneys to represent Mutual
    Benefits. Sixth, the bankruptcy court did not err in denying the Zeltser Group’s
    Rule 52(c) motion for judgment on partial findings and Rule 41(b) motion for
    involuntary dismissal.
    34
    Case: 12-15595     Date Filed: 02/20/2015   Page: 35 of 57
    The Zeltser Group, purportedly on behalf of Mutual Benefits, timely
    appealed District Court Judge Moore’s March 19, 2014 order to this Court.
    E.    Eleventh Circuit Appeals
    As detailed above, these bankruptcy proceedings culminated in separate
    appeals in this Court. On June 24, 2014, this Court consolidated, sua sponte, the
    appeals for purposes of disposition before a single oral argument panel after
    completion of briefing.
    IV. STANDARD OF REVIEW
    “In a bankruptcy case, this Court sits as a second court of review and thus
    examines independently the factual and legal determinations of the bankruptcy
    court and employs the same standards of review as the district court.” Brown v.

    V. BANKRUPTCY COURT’S AUTHORITY
    A.    Arguments on Appeal
    The Zeltser Group argues that the district court erred in denying its motion
    to withdraw reference of the Alleged Debtors’ Fisher Island and Little Rest cases
    because the bankruptcy court lacked constitutional authority under Stern to enter
    final judgment on the ownership issue, which is who owned the Alleged Debtors
    and who was entitled to represent them. The Zeltser Group contends that an
    objection to a bankruptcy court’s constitutional authority under Stern’s
    interpretation of 28 U.S.C. § 157 cannot be waived, and that its voluntary pre-Stern
    participation in pretrial proceedings did not constitute either express or implied
    consent to a non-jury trial before the bankruptcy court. Furthermore, the Zeltser
    Group contends that the district court erred in concluding that the bankruptcy court
    was necessarily required to resolve the ownership issue to rule on the merits of the
    creditors’ claims.
    As to Mutual Benefits specifically, the Zeltser Group argues that Stern
    deprived the bankruptcy court of the constitutional authority to enter a final
    judgment on the non-core issue of Mutual Benefits’ ownership, as opposed to a
    factual finding made to determine the interlocutory issue of who was authorized to
    retain counsel for Mutual Benefits.

    B.    Bankruptcy Court’s Statutory Authority under § 157
    Section 157 of the Judicial Code divides all matters that may be referred to
    the bankruptcy court into two categories: (1) core proceedings (those that “aris[e]
    under title 11” or “aris[e] in a case under title 11”) and (2) non-core proceedings
    (those that are not core but are “otherwise related to a case under title 11”). 28
    U.S.C. § 157(b)(1) , (3). Section 157(b)(2) sets forth a non-exhaustive list of
    sixteen types of core proceedings, including, in relevant part, “matters concerning
    the administration of the estate” and “other proceedings affecting . . . the
    adjustment of the debtor-creditor . . . relationship.” 
    Id. § 157(b)(2)(A),
    (O).
    The manner in which a bankruptcy court may act depends on the type of
    proceeding. In all core proceedings, bankruptcy courts have the authority to hear
    and enter final judgments. 
    Id. § 157(b)(1).
    In non-core proceedings, a bankruptcy
    court may only submit proposed findings of fact and conclusions of law to the
    district court, which then may enter final judgment after de novo review. 
    Id. § 157(c)(1).
    However, even in non-core proceedings, the parties may consent to
    entry of final judgment by the bankruptcy court. 
    Id. § 157(c)(2).
    C.    Stern v. Marshall
    On June 23, 2011, the Supreme Court issued its decision in Stern v.
    Marshall, which involved a voluntary bankruptcy proceeding. A creditor filed a
    defamation claim in the debtor’s voluntary bankruptcy proceeding, and the debtor
    37
    Case: 12-15595     Date Filed: 02/20/2015    Page: 38 of 57
    filed a state law counterclaim for tortious interference against the creditor. The
    bankruptcy court determined the tortious interference counterclaim to be a core
    proceeding under the plain language of § 157(b)(2)(C), which lists “counterclaims
    by the estate against persons filing claims against the estate” as one of the sixteen
    named types of core proceedings. The bankruptcy court then entered final
    judgment in the debtor’s favor on both the creditor’s defamation claim and the
    debtor’s tortious interference counterclaim. See Stern, 564 U.S. at __, 131 S. Ct. at
    2601-02.
    The Supreme Court determined that, while the bankruptcy court had
    statutory authority under § 157(b) to enter final judgment on the counterclaim, it
    violated Article III of the Constitution for Congress to confer that statutory
    authority onto the bankruptcy court. See id. at __, __, 131 S. Ct. at 2601, 2620.
    The debtor’s tortious-interference counterclaim was the type of common law cause
    of action that, in the federal system, is traditionally resolved by Article III courts.
    Id. at __, 131 S. Ct. at 2616. The Supreme Court reasoned that “Congress may not
    bypass Article III simply because a proceeding may have some bearing on a
    bankruptcy case; the question is whether the action at issue stems from the
    bankruptcy itself or would necessarily be resolved in the claims allowance
    process.” Id. at __, 131 S. Ct. at 2618; see also Katchen v. Landy, 
    382 U.S. 323
    ,

    86 S. Ct. 467
    , 472-73, 474-75 (1966) (holding that a bankruptcy
    38
    Case: 12-15595       Date Filed: 02/20/2015       Page: 39 of 57
    referee could exercise what was known as “summary jurisdiction” over a voidable-
    preference claim brought by a bankruptcy trustee against a creditor who had filed a
    proof of claim in the bankruptcy proceeding because the referee could not rule on
    the creditor’s proof of claim without first resolving the voidable-preference issue);
    Langenkamp v. Culp, 
    498 U.S. 42
    , 44-45, 
    111 S. Ct. 330
    , 331 (1990) (holding that
    a bankruptcy court could decide a preferential-transfer claim when the creditor
    filed a claim because then “the ensuing preference action by the trustee become[s]
    integral to the restructuring of the debtor-creditor relationship”). The Supreme
    Court ultimately held that the bankruptcy court “lacked the constitutional authority
    to enter a final judgment on a state law counterclaim that is not resolved in the
    process of ruling on a creditor’s proof of claim.” Stern, 564 U.S. at __, 131 S. Ct.

    The Supreme Court’s decision in Stern was based in part on its prior decision in
    Northern Pipeline Construction Co. v. Marathon Pipe Line Co., where the Supreme Court held
    that a bankruptcy court lacked constitutional authority to finally adjudicate a state-law contract
    claim against a non-creditor because the claim did not implicate what would become known as
    the “public rights” doctrine. 
    458 U.S. 50
    , 63-87, 
    102 S. Ct. 2858
    , 2867-2880 (1982) (opinion of
    Brennan, J., joined by Marshall, Blackmun, and Stevens, JJ.); 
    id. at 91,
    102 S. Ct. at 2882
    (Rehnquist, J., concurring, joined by O’Connor, J.). This “public rights” doctrine was described
    by the plurality in Northern Pipeline, which recognized that there was a category of cases
    involving “public rights” that Congress could constitutionally assign to “legislative” courts for
    resolution. The plurality stated that the “public rights” exception extended “only to matters
    arising between” individuals and the government “in connection with the performance of the
    constitutional functions of the executive or legislative departments . . . that historically could
    have been determined exclusively by those” branches. 
    Id. at 67-68,

    marks omitted); see also Granfinanciera, S.A. v. Nordberg,

    109 S. Ct. 2782
    , 2787, 2794-2802 (1989) (concluding that the particular fraudulent-conveyance claims at
    issue did not involve “public rights”).

    Importantly, in Stern, the Supreme Court rejected the creditor’s argument
    that the bankruptcy court lacked jurisdiction to adjudicate his defamation claim
    against the debtor. Id. at __, 131 S. Ct. at 2606-08. Because the allocation of
    authority between the bankruptcy court and the district court in § 157 “does not
    implicate questions of subject matter jurisdiction,” a party may consent to the
    bankruptcy court’s exercise of its statutory authority. See id. at __, 131 S. Ct. at
    2607-08 (noting that the creditor “repeatedly stated to the Bankruptcy Court that he
    was happy to litigate there,” and declining to “consider his claim to the contrary,
    now that he is sad”).
    D.     Analysis: Bankruptcy Court Was Authorized to Decide Ownership
    Issue
    As the Zeltser Group conceded before the district court, the ownership issue
    is a core matter that clearly “arises under” or “arises in a case under” chapter 11.
    Resolution of the threshold ownership issue was critical to the administration of
    the Alleged Debtors’ estates and directly affected the debtor-creditor relationship.
    See 28 U.S.C. § 157(b)(2)(A), (O). The bankruptcy court necessarily had to
    determine who actually owned the Alleged Debtors in order to adjudicate the
    After Northern Pipeline, “Congress revised the statutes governing bankruptcy
    jurisdiction” and “permitted the newly constituted bankruptcy courts to enter final judgments
    only in ‘core’ proceedings.” Stern, 564 U.S. at __, 131 S. Ct. at 2610. “With respect to such
    ‘core’ matters, however, the bankruptcy courts under the 1984 Act exercise the same powers
    they wielded under the Bankruptcy Act of 1978 (1978 Act), 92 Stat. 2549.” 
    Id. 40 Case:
    12-15595        Date Filed: 02/20/2015        Page: 41 of 57
    validity of the alleged $32 million debt, because the answer determined whether
    the Petitioning Creditors’ claims would be admitted or contested. See Stern, 564
    U.S. at __, 131 S. Ct. at 2616 (noting the Court’s prior holding that “summary
    adjudication [of a preference issue] in bankruptcy was appropriate, because it was
    not possible for the referee to rule on the creditor’s proof of claim without first
    resolving the voidable preference issue”). 11 Even assuming arguendo that the
    ownership issue was a non-core matter, the Zeltser Group expressly consented to
    the bankruptcy court’s final adjudication of the ownership issue and waived any
    argument to the contrary. 12 See 28 U.S.C. § 157(c)(2); Stern, 564 U.S. at __, 131
    S. Ct. at 2607-08. On several occasions during March 2011 to November 2011,
    the Zeltser Group made representations to the bankruptcy court, voluntarily
    participated in discovery, and appeared at hearing before the bankruptcy court—all
    indicating its willingness, in fact desire, for the bankruptcy court to decide the
    11
    Our finding that the ownership issue is “core” is consistent with holdings of courts in
    other circuits. Several courts have held that “control of a debtor-in-possession goes to the very
    heart of the administration of the debtor’s estate, [and] it necessarily follows that the bankruptcy
    court may properly determine where such control resides.” See Bank of Am., NT&SA v.
    Nickele, No. CIV.A. 98-1501, 
    1998 WL 181827
    , at *3 (E.D. Pa. Apr. 16, 1998); SCK Corp. v.
    Rosenblum (In re SCK Corp.), 
    54 B.R. 165
    , 169 (Bankr. D.N.J. 1984) (same); see also In re
    Louis J. Pearlman Enterprises, Inc., 
    398 B.R. 59
    , 64 (Bankr. M.D. Fla. 2008) (describing
    ownership of the alleged debtors as “core”).
    12
    Because the ownership issue here does not implicate the Article III concern identified in
    Stern, we do not reach the issue of whether a party may consent to the bankruptcy court’s
    adjudication of a Stern claim. See Exec. Bens. Ins. Agency v. Arkison, 573 U.S. __, __, 134 S.
    Ct. 2165, 2175 (2014) (expressly declining to decide whether a party can consent to trial of a
    Stern claim in the bankruptcy court). However, we do note in passing that both District Court
    Judges Huck and Williams conducted de novo review, and thus Article III concerns were
    mitigated here in any event.
    41
    Case: 12-15595     Date Filed: 02/20/2015    Page: 42 of 57
    ownership issue. The Zeltser Group was even happy to litigate in the bankruptcy
    court without objection for five months following the June 23, 2011 decision in
    Stern. The Zeltser Group also filed a motion for partial summary judgment in its
    favor on the ownership issue from the bankruptcy court but then a short time later
    inexplicably contested the bankruptcy court’s authority to decide it.
    Furthermore, we agree with the district court that the narrow holding in
    Stern—which concerned the bankruptcy court’s lack of constitutional authority to
    hear certain state common law counterclaims not necessarily resolved in the claims
    allowance process—is wholly inapplicable here. To be sure, in many respects, the
    ownership issue resembles the tortious-interference claim in Stern. Zeltser’s
    ownership claim is a state-law claim that does not involve “public rights” or stem
    from a federal statutory scheme. See Stern, 564 U.S. at __, 131 S. Ct. at 2614-15.
    It does not involve a particularized area of law. See id. at __, 131 S. Ct. at 2615.
    And unlike the preference actions in Katchen and Langenkamp (where the rights of
    recovery were created by federal bankruptcy law), ownership is not determined by
    bankruptcy law. However, unlike the tortious interference claim in Stern, the
    ownership issue was “necessarily resolve[d]” by the bankruptcy court through the
    process of adjudicating the creditors’ claims. See id. at __, 131 S. Ct. at 2616-17.
    The ownership issue does not simply have “some bearing” on the bankruptcy
    proceedings. See id. at __, 131 S. Ct. at 2618. Rather, for the reasons explained
    42
    Case: 12-15595        Date Filed: 02/20/2015       Page: 43 of 57
    above, the bankruptcy court could not undertake the bankruptcy proceedings
    without first determining who owned the Alleged Debtors, and thus who
    represented them, and ultimately whether the bankruptcy was contested or
    uncontested. See 
    Katchen, 382 U.S. at 329-30
    , 86 S. Ct. at 472-73 (affirming the
    bankruptcy court’s authority because the referee could not rule on the creditor’s
    proof of claim without first resolving the voidable preference issue). Determining
    who represented the Alleged Debtors, and thus whether the proceedings were
    contested or uncontested, was a threshold issue in this case.13 And although the
    relevant parties did not file a proof of claim, Zeltser invoked the aid of the
    bankruptcy court by asking it to adjudicate the ownership issue. As a result, it
    must abide by the consequences of that decision. Cf. Stern, 564 U.S. __, 
    131 S. Ct. 2594
    . Thus, the bankruptcy court had both statutory and constitutional authority to
    enter final judgment on the ownership issue.
    For all of these reasons, we conclude that the district court did not err in
    denying withdrawal of reference.
    13
    Even if ownership is not generally a core issue, the facts of this case make it core. As
    both district courts concluded: “Resolution of the ownership issue is deeply embedded—indeed,
    it is the primary issue—in the resolution of the creditors’ proofs of claim.” The bankruptcy court
    had to address the ownership dispute before it could adjudicate the underlying debt. If
    Imedinvest was the proper owner (and therefore the Zeltser Group represented the Alleged
    Debtors), the bankruptcy proceedings would be uncontested. If the Valmore Trust and Triangle
    were the proper owners (and the Redmond Group was the appropriate representative), the
    proceedings would be contested. Determining who represented the Alleged Debtors was, in this
    case, a core issue.
    43
    Case: 12-15595    Date Filed: 02/20/2015    Page: 44 of 57
    VI. FISHER ISLAND AND LITTLE REST—SUMMARY JUDGMENT
    A.     Arguments on Appeal
    The Zeltser Group alleges many procedural errors in the bankruptcy court’s
    January 20, 2012 summary judgment order in favor of the Redmond Group. First,
    the Zeltser Group argues that it lacked notice before the January 20, 2012 summary
    judgment order because the bankruptcy court’s preliminary December 29, 2011
    denial of the Zeltser Group’s motion for partial summary judgment only expressly
    named Miselva (not successor trustee SP Trustees) and Fisher Limited/Grosvenor
    (not their subsidiaries), and thus the bankruptcy court materially departed from that
    order when its summary judgment order ruled as to the ownership of Fisher Island
    and Little Rest. The Zeltser Group claims that it was unaware that the bankruptcy
    court would rule on the ownership of alleged debtors Fisher Island and Little Rest,
    thinking the bankruptcy court would limit its summary judgment order to the
    ownership of Fisher Limited and Grosvenor, their parent companies.
    Second, the Zeltser Group argues that the bankruptcy court did not comply
    with Rule 7056(f), which requires notice and an opportunity to respond before
    summary judgment may be granted sua sponte, by limiting its response to the
    existing record. Third, the Zeltser Group argues that the bankruptcy court
    improperly relied on the Examiner’s report, which constituted inadmissible
    44
    Case: 12-15595   Date Filed: 02/20/2015   Page: 45 of 57
    hearsay. These three claims of alleged procedural error are meritless and warrant
    no further discussion.
    The laundry list of objections does not end here. The Zeltser Group also
    argues that the bankruptcy court erred in allowing the ownership issue to proceed
    (1) as a contested matter raised in the Redmond Group’s motion to strike the
    Zeltser Group’s answers, instead of as an adversary proceeding, with its attendant
    procedural protections (i.e., the filing and service of a complaint and summons on
    all parties); and (2) without requiring joinder, under Federal Rule of Civil
    Procedure 19, of all “indispensable” parties having ownership interests in Fisher
    Island and Little Rest, including but not limited to the Valmore Trust, SP Trustees,
    Badri’s widow, and Imedinvest.
    Substantively, the Zeltser Group contends that material issues of disputed
    fact as to the ownership of Fisher Island and Little Rest precluded the entry of
    summary judgment. Specifically, the Zeltser Group argues that there were genuine
    disputes regarding the validity of the Valmore Trust, whether the JWL transfers
    were completed, and the applicability of the Gibraltar judgment to the bankruptcy
    proceedings.
    B.    Analysis
    As an initial matter, we note that the Zeltser Group raised its adversary-
    proceeding and mandatory-joinder arguments for the first time in its unsuccessful
    45
    Case: 12-15595     Date Filed: 02/20/2015    Page: 46 of 57
    November 30, 2011 motion for clarification/reconsideration of the agreed June 7,
    2011 Schedule Order. Prior to filing that motion, the Zeltser Group itself
    characterized the ownership issue as a “contested matter” in the Schedule Order (as
    well as in its motion for partial summary judgment). The Zeltser Group proceeded
    to litigate according to the Schedule Order for nearly six months without objection.
    Only after the issuance of the unfavorable Examiner’s report on November 18,
    2011, did the Zeltser Group suddenly decide that the ownership issue could not
    proceed as the parties had agreed.
    We are inclined to hold that the Zeltser Group forfeited its belated
    adversary-proceeding and mandatory-joinder arguments by failing to raise them
    before the bankruptcy court in any sort of timely manner. See United States v.
    Olano, 
    507 U.S. 725
    , 731, 
    113 S. Ct. 1770
    , 1776 (1993) (“No procedural principle
    is more familiar” than that a right may be forfeited “by the failure to make timely
    assertion of the right before a tribunal having jurisdiction to determine it.”
    (quotation omitted)). To quote the Supreme Court in Stern, the Zeltser Group
    “repeatedly stated to the Bankruptcy Court that [it] was happy to litigate there.”
    564 U.S. at __, 131 S. Ct. at 2608. We will not consider its arguments to the
    contrary, “now that [it] is sad.” 
    Id. In any
    event, the Zeltser Group’s arguments
    fail on the merits, as discussed below.
    46
    Case: 12-15595      Date Filed: 02/20/2015     Page: 47 of 57
    1.     Adversary Proceeding
    The Federal Rules of Bankruptcy Procedure distinguish between adversary
    proceedings and contested matters. Adversary proceedings under Rule 7001
    incorporate much of the Federal Rules of Civil Procedure. See Fed. R. Bankr. P.
    7001 advisory committee’s note. Rule 7001 lists ten types of matters which must
    be brought as adversary proceedings, including “proceeding[s] to determine the
    validity, priority, or extent of a lien or other interest in property . . . .” Fed. R.
    Bankr. P. 7001(2). In contrast, contested matters are subject to less elaborate
    procedures specified in Rule 9014. “In a contested matter not otherwise governed
    by these rules, relief shall be requested by motion, and reasonable notice and
    opportunity for hearing shall be afforded the party against whom relief is sought.”
    Fed. R. Bankr. P. 9014(a).
    Contrary to the Zeltser Group’s argument, the bankruptcy court’s
    determination of the ownership issue was not a “proceeding to determine the
    validity . . . [of an] interest in property” under Rule 7001(2), and thus an adversary
    proceeding was not required. The validity of the $32 million debt alleged by the
    Petitioning Creditors, the only property interest at stake here, has not yet been
    adjudicated. The bankruptcy court resolved the threshold issue of ownership for
    purposes of determining who was authorized to represent the Alleged Debtors with
    respect to that debt. Furthermore, the bankruptcy court afforded the parties with
    47
    Case: 12-15595     Date Filed: 02/20/2015    Page: 48 of 57
    essentially the same procedural protections applicable in adversary proceedings,
    providing the Zeltser Group with more than adequate “notice and opportunity for
    hearing.” See Fed. R. Bankr. P. 9014(a). Accordingly, the bankruptcy court did
    not err in allowing the ownership issue to proceed as a contested matter.
    2.     Mandatory Joinder
    The mandatory joinder requirements in Rule 19, made applicable to
    adversary proceedings by Federal Rule of Bankruptcy Procedure 7019, do not
    apply to contested matters such as these. See Fed. R. Bankr. P. 1018; Fed. R. Civ.
    P. 19 (setting forth a two-step test to determine whether a party is necessary and
    indispensable to an action). Even if Rule 19 did apply here, the Zeltser Group did
    not meet its burden of proving that the parties not joined were both necessary and
    indispensable to the proceeding.
    The Zeltser Group’s appellate brief fails to articulate a single non-
    conclusory reason for why the bankruptcy court could not grant complete relief
    among the existing parties without joining the over a dozen non-parties identified
    by the Zeltser Group, or why the absence of these non-parties impeded their ability
    to protect their interests or subjected an existing party to a substantial risk of
    inconsistent obligations. See Fed. R. Civ. P. 19(a)(1). In fact, the Zeltser Group,
    purportedly on behalf of the Alleged Debtors, admitted to the alleged debt at the
    48
    Case: 12-15595     Date Filed: 02/20/2015    Page: 49 of 57
    outset of the proceedings, indicating that they believed the involuntary petitions
    could be adjudicated without any additional parties.
    3.     Merits of Summary Judgment
    Under Rule 56, as incorporated by Federal Rule of Bankruptcy Procedure
    7056, a court “shall grant summary judgment if the movant shows that there is no
    genuine dispute as to any material fact and the movant is entitled to judgment as a
    matter of law.” Fed. R. Civ. P. 56(a). The court may, after giving notice and a
    reasonable time to respond, grant summary judgment for a nonmovant or consider
    summary judgment on its own after identifying for the parties material facts that
    may not be genuinely in dispute. Fed. R. Civ. P. 56(f). A court may sua sponte
    grant summary judgment “so long as the losing party was on notice that [it] had to
    come forward with all of [its] evidence.” Celotex Corp. v. Catrett, 
    477 U.S. 317
    ,
    326, 
    106 S. Ct. 2548
    , 2554 (1986). “A party asserting that a fact . . . is genuinely
    disputed must support the assertion by . . . citing to particular parts of materials in
    the record . . . or . . . showing that the materials cited do not establish the absence
    or presence of a genuine dispute.” Fed. R. Civ. P. 56(c).
    Here, the record demonstrates no genuine issue of material fact as to the
    ownership of Fisher Island and Little Rest. We are not persuaded by the Zeltser
    Group’s unsubstantiated arguments to the contrary, particularly given the Zeltser
    Group’s total failure to raise any purported factual dispute in response to the
    49
    Case: 12-15595     Date Filed: 02/20/2015   Page: 50 of 57
    bankruptcy court’s December 29, 2011 invitation to submit briefing. The Zeltser
    Group may not refuse to raise disputed issues before the bankruptcy court then
    later claim on appeal that disputed issues precluded summary judgment. Thus, the
    bankruptcy court correctly granted summary judgment sua sponte in favor of the
    Redmond Group.
    VII. STANDING OF NON-PARTY APPELLANTS
    Three non-party appellants—Fisher Limited, Grosvenor, and Areal—
    contend that the district court erred in dismissing their appeals of the bankruptcy
    court’s January 20, 2012 summary judgment order for lack of standing.
    A.    Non-Parties Fisher Limited and Grosvenor
    Non-party appellants Fisher Limited and Grosvenor argue that the district
    court erred in requiring them to intervene, attend, or object in the bankruptcy
    proceedings in order to appeal the bankruptcy court’s summary judgment order.
    They argue that the prudential “attend and object” prerequisite to standing is not
    recognized in this circuit and does not preclude a non-party purportedly bound by a
    judgment by the bankruptcy court from appealing that judgment to the district
    court and to this Court.
    Fisher Limited and Grosvenor further argue that the bankruptcy court lacked
    personal jurisdiction to enter a judgment granting ownership of them to SP
    Trustees because they were not served with process. According to Fisher Limited
    50
    Case: 12-15595     Date Filed: 02/20/2015    Page: 51 of 57
    and Grosvenor, they may appeal the bankruptcy court’s improper exercise of
    personal jurisdiction without having had to intervene or participate. Furthermore,
    they argue that the Redmond Group’s failure to initiate an adversary proceeding
    and join all indispensable parties excused any requirements of attendance or
    objection.
    B.    Non-Party Areal
    Similarly, non-party appellant Areal argues that the district court erred by
    imposing the “appear and object” requirement because the “person aggrieved”
    standard is the only prerequisite to non-party standing. Areal does not dispute that
    it was on notice of the bankruptcy proceedings, but rather contends that the district
    court improperly placed the burden on Areal to intervene and object.
    According to Areal, the district court also erred procedurally in determining
    whether Areal was “aggrieved” by the bankruptcy court order. Specifically, Areal
    argues that the district court erred by: (1) discrediting the pledge agreement
    without conducting an evidentiary hearing to allow Areal to address disputed
    factual issues raised for the first time in the Redmond Group’s reply (but not the
    initial motion to dismiss); and (2) making findings as to the substantive merits of
    Areal’s ownership claim in Little Rest without a trial.

    C.     Analysis
    To determine whether a person or entity has standing to appeal a bankruptcy
    court’s order, we apply bankruptcy law’s “person aggrieved” doctrine as a
    prudential standing requirement. Westwood Cmty. Two Ass’n, Inc. v. Barbee (In
    re Westwood Cmty. Two Ass’n, Inc.), 
    293 F.3d 1332
    , 1334-35 (11th Cir. 2002).
    Under the “person aggrieved” doctrine, a person has standing to appeal only when
    he is “directly and adversely affected pecuniarily by the order.” 
    Id. at 1335
    (quotation omitted). In other words, the person must have a financial stake in the
    appealed order such that the order “diminishes their property, increases their
    burdens or impairs their rights.” 
    Id. (quotation omitted).14
    The three non-party
    appellants have not met this requirement here.
    Non-parties Fisher Limited and Grosvenor’s arguments in favor of their
    standing are largely based on the erroneous proposition that the bankruptcy court’s
    summary judgment order “awarded them” to SP Trustees or otherwise bound them
    as parties. Fisher Limited and Grosvenor are undisputedly the respective parent
    companies of Fisher Island and Little Rest, two of the Alleged Debtors. The
    summary judgment order did not disturb Fisher Limited’s or Grosvenor’s claims to
    14
    In a footnote, this Court noted that this holding was “limited to defining a person
    aggrieved in this circuit, which is only one of many hurdles a person must overcome to have
    standing to appeal. The Bankruptcy Code also contains certain procedural requirements,
    including attendance at bankruptcy hearings, intervention, and filing a notice of appeal within
    certain time limits.” 
    Id. at 1338
    n.8. District Court Judge Williams cited to this footnote to
    support her application of an “attend and object” prerequisite to standing.
    52
    Case: 12-15595     Date Filed: 02/20/2015    Page: 53 of 57
    ownership over Fisher Island and Little Rest. The order merely named Fisher
    Limited and Grosvenor as part of the ownership chain for purposes of setting forth
    who had the authority to appoint counsel to represent alleged debtors Fisher Island
    and Little Rest in the bankruptcy proceedings. Non-parties Fisher Limited and
    Grosvenor have not shown the requisite financial stake in the order—it did not
    diminish their property, increase their burdens, or impair their rights. See In re
    
    Westwood, 293 F.3d at 1335
    .
    As to non-party Areal, we find no error in the district court’s dismissal of the
    appeal based on Areal’s failure to show that it was a “person aggrieved” by the
    bankruptcy court’s summary judgment order. We note that Areal does not contest,
    as substantive error, any of the district court’s fact findings as to the authenticity of
    the pledge agreement purportedly showing Areal’s pecuniary interest in Little Rest.
    Areal submitted no other evidence of its financial stake in the order.
    Because we conclude that the non-party appellants failed to meet their
    burden of demonstrating their status as “persons aggrieved,” we need not decide
    whether attendance and objection in the bankruptcy proceedings is a prerequisite
    for prudential standing in bankruptcy appeals. See Big Top Koolers, Inc. v.
    Circus-Man Snacks, Inc., 
    528 F.3d 839
    , 844 (11th Cir. 2008) (appellate court can
    affirm on any ground supported by the record). We also conclude that the three
    53
    Case: 12-15595     Date Filed: 02/20/2015   Page: 54 of 57
    non-party appellants’ remaining arguments lack merit and therefore warrant no
    further discussion.
    VIII. MUTUAL BENEFITS—FINAL JUDGMENT
    A.    Arguments on Appeal
    As in the Fisher Island and Little Rest cases, the Zeltser Group contends that
    the bankruptcy court erred by allowing the ownership issue to proceed as a
    contested matter rather than as an adversary proceeding. Without joinder of all
    indispensable parties in a properly-commenced adversary proceeding, the
    bankruptcy court lacked in personam jurisdiction to finally adjudicate the
    ownership rights of non-party shareholders in Mutual Benefits, and lacked in rem
    jurisdiction over the disputed property (i.e., Mutual Benefits’ stock owned by the
    non-party shareholders). For essentially the same reasons discussed above in Parts
    VI.B.1-2, we disagree.
    Next, the Zeltser Group argues that the bankruptcy court (1) abused its
    discretion in denying a continuance, (2) erred in denying its Rule 52(c) motion for
    judgment on partial findings and its Rule 41(b) motion for involuntary dismissal,
    and (3) erred in basing the final judgment on factual findings unsupported by the
    record. First, the Zeltser Group argues that the denial of a continuance severely
    prejudiced its presentation of the direct testimony of its key witnesses in support of
    its case in chief. Second, the Zeltser Group contends the bankruptcy court applied
    54
    Case: 12-15595      Date Filed: 02/20/2015     Page: 55 of 57
    the incorrect legal standard in ruling on the Rule 52(c) and Rule 41(b) motions by
    failing to weigh the evidence presented or consider witness credibility. Third, the
    Zeltser Group submits that the bankruptcy court clearly erred in ultimately finding
    that Davis had authority to act on behalf of Mutual Benefits.
    B.     Analysis
    1.     Denial of Continuance
    The denial of a continuance is not an abuse of discretion unless it “severely
    prejudices” the moving party. Rink v. Cheminova, Inc., 
    400 F.3d 1286
    , 1296 (11th
    Cir. 2005). We consider four factors to determine whether the denial of a
    continuance constitutes an abuse of discretion: (1) the moving party’s diligence in
    its efforts to ready the case for trial; (2) the likelihood that the need for a
    continuance would have been remedied had the continuance been granted; (3) the
    extent to which granting the continuance would have inconvenienced the court and
    the opposing party; and (4) the extent to which the moving party might have
    suffered harm as a result of the denial. 
    Id. We agree
    with the district court’s thorough and reasoned analysis of these
    four factors. The record is utterly devoid of any indication that the bankruptcy
    court’s denial of a 60-day continuance, requested 10 days before the scheduled trial
    date, “severely prejudiced” the Zeltser Group. See 
    id. Thus, we
    conclude that the
    bankruptcy court did not abuse its discretion in doing so.
    55
    Case: 12-15595     Date Filed: 02/20/2015   Page: 56 of 57
    2.     Denial of Rule 52(c) and Rule 41(b) Motions
    Rule 52(c) provides as follows:
    Judgment on Partial Findings. If a party has been fully heard on an
    issue during a nonjury trial and the court finds against the party on
    that issue, the court may enter judgment against the party on a claim
    or defense that, under the controlling law, can be maintained or
    defeated only with a favorable finding on that issue. The court may,
    however, decline to render any judgment until the close of the
    evidence. A judgment on partial findings must be supported by
    findings of fact and conclusions of law as required by Rule 52(a).
    Fed. R. Civ. P. 52(c) (emphasis added). A prior version of Rule 41(b) contained
    similar discretionary language. See Caro-Galvan v. Curtis Richardson, Inc., 
    993 F.2d 1500
    , 1503 n.7 (11th Cir. 1993) (substance of the former Rule 41(b) is found
    in the current version of Rule 52(c)).
    The Zeltser Group argues that, in ruling on its motions, the bankruptcy court
    was required to consider witness credibility and to weigh the evidence presented.
    However, even if the bankruptcy court applied the wrong legal standard (i.e., the
    standard for summary judgment), it ultimately found the Redmond Group’s
    testimonial and documentary evidence to be credible and persuasive, and entered
    final judgment on that basis. There is no indication that, had the bankruptcy court
    considered Davis’s credibility and weighed the Redmond Group’s evidence, the
    court would have exercised its discretion to grant either motion midway through
    trial. Thus, the bankruptcy court’s statement that a Rule 52(c) or Rule 41(b)
    motion was “in some way similar to a summary judgment motion” amounted, at
    56
    Case: 12-15595     Date Filed: 02/20/2015   Page: 57 of 57
    most, to harmless error. See Club Assocs. v. Consol. Capital Realty Investors (In
    re Club Assocs.), 
    951 F.2d 1223
    , 1234 n.13 (11th Cir. 1992).
    3.     Final Judgment
    Here, all of the evidence at the Mutual Benefits trial came from the
    Redmond Group. Despite offering enough evidence to defeat summary judgment
    and submitting extensive witness and exhibit lists, the Zeltser Group failed put on
    any case whatsoever at trial as to any alternative ownership theory as to Mutual
    Benefits. Given the evidence in this record, we conclude the bankruptcy court did
    not err—much less clearly err—in finding that Davis, the president and sole
    director of Mutual Benefits, had the exclusive authority to retain counsel to
    represent Mutual Benefits, and that, pursuant to this authority, Davis retained the
    Redmond Group’s attorneys in the bankruptcy proceeding. Accordingly, the
    bankruptcy court did not err in entering final judgment on the ownership issue in
    the Mutual Benefits case.
    IX. CONCLUSION
    Finding no reversible error in any order on appeal, we AFFIRM.
