SMITH, TRACY M., Judge

       Appellants Masjed Abubakr Al-Seddiq, Inc. (MAAS), North American Islamic

Trust, Inc. (NAIT), Mohammed Bouarfa, Tanveer Zubair, Muhyadin Musse, Said Hajiali,

and Rashed Ferdous challenge the district court’s denial of MAAS and NAIT’s motion for

summary judgment, arguing that the Establishment Clause of the United States

Constitution and an arbitration clause deprive the district court of jurisdiction over this

case.1 Because we agree with the district court that (1) it is premature to decide that

resolution of this case will necessarily involve improper government entanglement with

religion and (2) appellants have waived their arbitration-clause argument, we affirm.

                                          FACTS2

       This dispute involves two nonprofit corporations—MAAS and respondent United

Islamic Society (UIS)—each claiming to be the rightful beneficiary of properties held in

  This appeal was filed by all appellants listed above, but the individual appellants did not
join in MAAS and NAIT’s motion for summary judgment in the district cout.
2
  As further described below, this appeal involves two consolidated cases. In an effort to
resolve one of those cases, the parties submitted stipulated facts, including exhibits, to the
district court. The stipulated facts were later relied upon by the district court in ruling on
the summary-judgment motion at issue in this appeal. The facts here are drawn from the
parties’ stipulated facts.

                                              2
trust by NAIT for the benefit of the Rochester Muslim community. MAAS, founded in

1995, is the older of the two organizations and played a key role in the establishment of the

Masjed Abubakr Al-Seddiq (the mosque) at the center of this dispute. UIS was established

in 2007 and has run the day-to-day affairs of the mosque since 2008. Both nonprofits are

located at the same address as the mosque. The properties at issue in this dispute are (1) the

Masjed Abubakr Al-Seddiq property located at 17 North Broadway in Rochester (the

mosque property), which was conveyed by warranty deed to MAAS in 1996; (2) cemetery

plots in Rochester’s Oakwood East Cemetery that were purchased by MAAS in 2001 and

2006; and (3) agricultural land outside Rochester that was purchased in 2001 by Rochester

Islamic Center (RIC).

       In 2007, MAAS and RIC had a dispute regarding the management and financial

affairs of the mosque. The organizations turned to Bouarfa, who had been the mosque’s

first Imam and who had retired as MAAS’s president, to broker a solution. Bouarfa called

a meeting at the mosque on October 30, 2007. The attendees agreed that the mosque

property, agricultural land, and cemetery plots would be conveyed to NAIT as trustee and

that a new organization would be formed to manage the mosque. The attendees also agreed

that all previous and current board members of MAAS and RIC, including MAAS’s

treasurer, Zubair, would be ineligible for election to the new organization’s board, but that

Bouarfa and one other MAAS board member were exempt from this prohibition. It was

further agreed that RIC would transfer the agricultural land to MAAS and MAAS would

control the mosque bank accounts and all of the properties until the transfer to NAIT was

complete, at which point MAAS’s board members would resign. The meeting attendees


                                              3
appointed the mosque’s new Imam to lead the new organization and gave him authority to

select other board members. Twenty individuals signed the meeting minutes describing

these agreements.

       On the same day as this meeting, NAIT’s executive director, Mujeeb Cheema, sent

an e-mail to a MAAS board member, responding to a request for information. Cheema

described the steps needed to implement a trust, including execution of a declaration of

trust, and explained that NAIT would act as the trustee and “the local entity and its

community” would be the beneficiary. Cheema also included a description of “NAIT’s

Waqf Services,” which states that mosques “are held by a Waqf (Islamic trust)

institution . . . to serve the Islamic objectives prescribed at inception.”

       In accordance with the October 30, 2007 agreement, RIC conveyed the agricultural

land to MAAS on November 1, 2007. The Imam incorporated the new organization, UIS,

in December 2007 and held elections for its board. UIS began running the day-to-day

affairs of the mosque. MAAS’s board then executed a resolution stating that MAAS assets

would be given to NAIT as trustee and that the mosque would be leased to UIS. According

to the resolution, all MAAS board members resigned except Bouarfa and one additional

contact person.

       For the better part of the next two years, MAAS held the properties. During this

time, Cheema sent various e-mails, in which he requested completion of warranty deeds

and trust documents, and inquired whether UIS or MAAS would be the trust beneficiary.

       On October 17, 2009, MAAS conveyed the mosque property and the agricultural

land to NAIT in separate warranty deeds. Neither deed references the cemetery plots. The


                                               4
warranty deeds state that MAAS transferred the properties to NAIT “[f]or valuable

consideration of the desire to follow Islamic princip[le]s of Waqf (Islamic Trust).” Cheema

then sent an e-mail asking whether MAAS or UIS should be listed as the trust beneficiary.

Cheema explained that, as the grantor, MAAS could designate itself as beneficiary or

designate UIS as beneficiary and that, “[i]n addition, your community will remain

beneficiary.” In a November 2009 e-mail, Cheema stated: “Based on our conversation:

The [Masjed Abubakr Al Seddiq] and its community will be the [beneficiary] of the two

entrusted properties . . . .”

       Little of note happened regarding the trust in 2010 and 2011.

       In January 2012, Cheema sent a letter to UIS stating that NAIT holds real estate in

trust for the Muslim community and MAAS and that UIS is not a beneficiary of the trust.

During January and February 2012, Bouarfa appointed Zubair as the “sole person

responsible for all of the affairs” of MAAS and then made Zubair MAAS’s vice president

with the power to perform the duties of president in the president’s absence.

       On March 8, 2012, Cheema sent an e-mail to Bouarfa and Zubair, asking for

completion of a declaration of trust. On March 12, Zubair and Cheema executed a

declaration-of-trust agreement between NAIT and MAAS regarding the mosque property

and the agricultural land. The declaration lists NAIT as the trustee and MAAS as both the

grantor and the beneficiary of the trust. The declaration recognizes that MAAS conveyed

the property to NAIT “IN TRUST (WAQF),” with NAIT holding title to the property “In

Trust (Waqf) for the benefit of the Beneficiary and its community.” The declaration

explains that, “in the Islamic tradition, the title to religious properties, including mosques,


                                              5
Islamic centers, and schools are held by a Waqf (Islamic trust and Islamic endowment[]

institutions),” that “a major objective of NAIT is to serve as a Waqf institution,” and that

the property “is to be declared a Waqf property.” The declaration of trust also contains an

arbitration clause under which MAAS and NAIT agree to submit disputes regarding

appropriate use of the property, successor trustees, and successor beneficiaries to

arbitration “by a FIQH Committee of reputable Muslims in the United States.”

       UIS filed two lawsuits regarding the trust and the properties: (1) a civil action

asserting several claims against MAAS, NAIT, and the individual defendants for

declaratory, injunctive, and other relief, including damages; and (2) a trust petition

requesting determinations regarding the nature and extent of UIS’s interest in the trust and

removal of NAIT as trustee.

       In the hope of resolving the trust-petition action without a trial, the parties submitted

stipulated facts and written arguments to the district court. After the matter was submitted,

appellants wrote to the district court and suggested that the district court may not have

subject-matter jurisdiction over the dispute due to the Establishment Clause of the United

States Constitution. UIS objected to appellants’ argument.

       In its order regarding the trust petition, the district court described the proceeding

as “akin to cross-motions for summary judgment” and concluded that it could not make a

determination on the merits “without further oral argument or an evidentiary hearing.”

Regarding UIS’s Establishment Clause argument, the district court stated that the dispute

may require the court to determine the meaning of “waqf” but that it “is skeptical of the

suggestion that it will be impossible to resolve the issues raised in the [p]etition by neutral


                                               6
principles of law and without regard to religious doctrines.” The district court also

expressed concern, sua sponte, that (1) the purported trust created by MAAS might be an

illegal passive trust and (2) the arbitration clause in the declaration of trust might compel

the parties to arbitrate their dispute.

       UIS’s lawsuits were then consolidated, and the district court heard arguments on

several motions for summary judgment. In relevant part, the district court denied MAAS

and NAIT’s motion for summary judgment.3 Regarding the Establishment Clause issue,

the district court determined that “it appears at this stage that the matter can be resolved

using ordinary principles of law,” but that the district court could “revisit the issue if it

becomes apparent, at any time, that resolution will require analysis of the tenets and beliefs

of Islam.”    Regarding the arbitration-clause issue, the district court determined that

appellants had waived their argument by not requesting arbitration earlier.

       This appeal follows.

                                          DECISION

       A district court must grant summary judgment “if the pleadings, depositions,

answers to interrogatories, and admissions on file, together with the affidavits, if any, show

that there is no genuine issue as to any material fact and that either party is entitled to a

judgment as a matter of law.” Minn. R. Civ. P. 56.03. “Generally, an interlocutory appeal

may not be taken from a denial of summary judgment, but an issue relating to subject-

 The district court also denied Zubair’s motion for summary judgment, with the exception
of the trespass claim against him. The denial of Zubair’s motion for summary judgment is
not at issue in this appeal.

matter jurisdiction is appealable immediately.”        J.M. v. Minn. Dist. Council of the

Assemblies of God, 658 N.W.2d 589, 593 (Minn. App. 2003). We review subject-matter-

jurisdiction questions de novo. Id. We also review constitutional-interpretation questions

de novo. Pfeil v. St. Matthews Evangelical Lutheran Church, 877 N.W.2d 528, 536 (Minn.

2016).

                                               I.

         Appellants argue that the Establishment Clause of the United States Constitution

deprives the district court of subject-matter jurisdiction over UIS’s lawsuits and that the

district court therefore erred by not granting MAAS and NAIT’s motion for summary

judgment. After appellants filed their principal brief in this appeal, the Minnesota Supreme

Court clarified that the “ecclesiastical abstention doctrine,” which “has its roots in a line of

U.S. Supreme Court decisions regarding church property and church schisms,” does not

implicate subject-matter jurisdiction and is “not a jurisdictional bar.” Id. at 532, 534-35.

The supreme court declined to decide whether the doctrine should be “viewed as an

affirmative defense on the merits or a form of abstention” because the issue was not briefed

or necessary to the outcome of the case. Id. at 535. Such a determination is similarly

unnecessary in this appeal.

         Reviewing the jurisprudential history of the ecclesiastical abstention doctrine, the

supreme court in Pfeil drew several principles from governing United States Supreme

Court cases:

               First, a court cannot overturn the decisions of governing
               ecclesiastical bodies with respect to purely ecclesiastical
               concerns, such as internal church governance or church


                                               8
              discipline. Second, a court may not entertain cases that require
              the court to resolve doctrinal conflicts or interpret church
              doctrine. Finally, a court may decide disputes involving
              religious organizations, but only if the court is able to resolve
              the matter by relying exclusively on neutral principles of law,
              the court does not disturb the ruling of a governing
              ecclesiastical body with respect to issues of doctrine, and the
              adjudication does not “interfere with an internal church
              decision that affects the faith and mission of the church itself.”

Id. at 534 (quoting Hosanna-Tabor Evangelical Lutheran Church & School v. EEOC, 132

S. Ct. 694, 707 (2012)) (citations omitted).

       The supreme court further explained that it has “traditionally analyzed the

ecclesiastical abstention doctrine as an Establishment Clause question and applied the

three-pronged test announced in Lemon v. Kurtzman.” Id. at 536-37 (citing Lemon, 403

U.S. 602, 612-13, 91 S. Ct. 2105, 2111 (1971)). Under the Lemon test, state action is

invalid under the Establishment Clause if it “(1) lacks a secular purpose; (2) has the primary

effect of advancing or inhibiting religion; or (3) fosters excessive entanglements with

religion.” State v. Wenthe, 839 N.W.2d 83, 87 (Minn. 2013); see also Lemon, 403 U.S. at

612-13, 91 S. Ct. at 2111; Pfeil, 877 N.W.2d at 537.4 As the Pfeil court recognized,

however, the United States Supreme Court has grounded the ecclesiastical abstention

doctrine in not only the Establishment Clause but also in the Free Exercise Clause,

evaluating whether adjudicating a claim would interfere with an internal decision that

would impact the religious organization’s faith or mission. 877 N.W.2d at 537 (discussing



4
 The first two prongs of the Lemon test—whether state action lacks a secular purpose or
has the primary effect of advancing or inhibiting religion—are not at issue in this case.


                                               9
Hosanna-Tabor, 132 S. Ct. at 707). The supreme court in Pfeil concluded that the analyses

under the excessive-entanglement prong of the Lemon test and the Free Exercise Clause

“appear to be substantially similar inquiries.”       Id.     Thus, a court evaluating an

ecclesiastical-abstention challenge must determine whether adjudication will foster

excessive government entanglement with religion or interfere with an internal church

decision affecting the faith and mission of the church. Id.

       “Under the entanglement doctrine, a state may not inquire into or review the internal

decisionmaking or governance of a religious institution.” Odenthal v. Minn. Conference

of Seventh-Day Adventists, 649 N.W.2d 426, 435 (Minn. 2002). “No entanglement

problem exists, however, when civil courts use neutral principles of law—rules or

standards that have been developed and are applied without particular regard to religious

institutions or doctrines—to resolve disputes even though those disputes involve religious

institutions or actors.” Wenthe, 839 N.W.2d at 90.

       Here, there has been no ruling from a governing ecclesiastical body regarding the

trust, and there is therefore no governing-body ruling to disturb. See Pfeil, 877 N.W.2d at

534. What remains for analysis is (1) whether the district court may resolve this case by

applying neutral principles of law and (2) whether the adjudication will interfere with an

internal church decision affecting the faith and mission of the church. See id.

Neutral Principles of Law

       The state has “‘an obvious and legitimate interest in the peaceful resolution of

property disputes, and in providing a civil forum where the ownership of church property

can be determined conclusively.’” Piletich v. Deretich, 328 N.W.2d 696, 700 (Minn. 1982)


                                            10
(quoting Jones v. Wolf, 443 U.S. 595, 602, 99 S. Ct. 3020, 3024 (1979)). When analysis

of a property dispute depends upon documents such as deeds, church bylaws, and the

church constitution, a dispute can be resolved according to neutral principles of law. Id.

In such cases, a court may “resolve questions of which of two factions of a local

congregation is entitled to possess and enjoy property.” Id.

       The district court relied on Piletich to deny MAAS and NAIT’s summary-judgment

motion. Piletich involved “a dispute over the identity of persons entitled to [a church’s]

real and personal property.” Id. at 698. A majority of the congregation voted not to

recognize a reorganization of the church’s diocese and acquired possession and control of

the property. Id. A minority faction then sued, alleging that it was entitled to the church

property. Id. The supreme court characterized the action as “a matter of property

ownership and membership qualification, to be determined by documents and proceedings

of the local church government.” Id. at 700. According to the supreme court, “state courts

may avoid entanglement problems by applying principles of law in a purely secular

manner, taking care not to decide disputes on the basis of doctrinal matters, and deferring

to decisions of church hierarchy only when church rules or constitutions or state statutes

specifically require.” Id. at 701. Because the issue in Piletich was not doctrinal and the

church was not hierarchical, the supreme court applied the neutral rule of majority

representation to affirm the district court’s grant of summary judgment to the majority

faction.   Id. at 699-700, 702-03.     “Looking only at the deeds, charter, bylaws and

Constitution of the Mother Church, we find that control over church property resides in the

majority of the local congregation in this case.” Id. at 703.


                                             11
       The district court determined that, as in Piletich, “the dispute here is not doctrinal

in nature” and there is no evidence that “the local Muslim community is hierarchical with

respect to intra-congregational disputes over local property.” The district court therefore

determined that, like a dispute between two secular nonprofit corporations, UIS’s

allegations could be analyzed according to trust law and the rule of majority representation,

both neutral principles of law.

       Appellants argue that Piletich is distinguishable because Piletich involved the

neutral principle of majority rule and here, appellants assert, UIS does not claim to

represent the majority of mosque members. But the district court is correct that under

Piletich majority rule is a neutral principle of law for resolving a church property dispute;

whether that rule will be used to resolve this case goes to the merits and not to the issue of

entanglement.    Appellants argue, however, that if majority rule is asserted, merely

determining the majority faction would require interpretation of religious doctrine. Should

UIS pursue a majority-representation claim based on religious doctrine, the district court

can address the issue then.

       Appellants also argue that Piletich is distinguishable because the district court will

need to analyze religious doctrine to decide which party is the beneficiary of the trust and

whether NAIT should be removed as trustee. Specifically, appellants assert that UIS’s

claims require the district court to analyze the religious term “waqf” to determine when a

trust was created, whether UIS is fulfilling Islamic objectives for the community, and

whether NAIT is fulfilling its duties as trustee. UIS counters that its claims can be decided

without resolving doctrinal issues, and, to the extent appellants believe that UIS will rely


                                             12
on religious doctrine to support its claims, their concern is premature and can be addressed

by the district court if and when that happens.

       A determination of whether this case can be resolved using neutral principles of law

depends upon a close reading of UIS’s civil complaint and trust petition. In its civil

complaint, UIS makes no mention of any religious doctrine and does not request relief for

religious reasons. UIS instead requests a determination that it is the intended beneficiary

of the trust based on the lease, warranty deeds, meeting minutes, and MAAS resolution. In

its trust petition, UIS similarly requests a determination that UIS is the trust beneficiary

and removal of NAIT as trustee “for cause.”

       But UIS’s trust petition also includes an allegation that “the properties were

transferred to NAIT to be held in ‘waqf,’ which is an Arabic word meaning endowment

typically of a building or plot of land for religious or charitable purposes.” The petition

also alleges that NAIT “has attempted to interfere with the religious services at the

mosque.” Finally, in its memorandum in support of its trust petition, UIS cites the language

in the warranty deeds regarding “waqf” as evidence that the parties intended a trust

relationship and that NAIT had an enforceable duty as trustee to hold the properties in

accordance with Islamic law.5

       More concerning, UIS argued in its memorandum that “waqf” requires the

properties to be held in trust with a charitable purpose of teaching the Islamic religion, and



5
  In context, this latter argument in UIS’s memorandum appears intended to refute the
district court’s concern that the transaction created a passive trust, rather than intended to
request relief based on a religious doctrine.

                                             13
that UIS “is the organization that advances this charitable purpose.” Contrary to the

assertion otherwise in its brief, UIS specifically argued that “[t]he phrase ‘Waqf (Islamic

Trust)’ and the surrounding circumstances are sufficient to designate the community and

its representative as the beneficiary of the trust.” Appellants point to this section of UIS’s

argument as evidence that the district court will have to determine the meaning of “waqf”

to resolve the parties’ dispute.

       We disagree with appellants that determining which party is the trust beneficiary

necessarily requires resolution of a dispute over the meaning of a religious term or a

determination of which party fulfills the trust’s purpose to serve Islamic objectives. If the

district court declares the declaration of trust valid, there appears to be no reason to interpret

or analyze “waqf.” Similarly, if the district court declares the declaration of trust invalid,

as UIS requests, a beneficiary determination likely depends on testimony and the

documents in the record regarding the parties’ intent, which may include, among others,

the warranty deeds that reference “Waqf (Islamic trust).” Although the warranty deeds

reference “waqf,” they do not name a beneficiary or suggest that the beneficiary must

comply with any “waqf” requirements. The limited information in the record about “waqf”

simply does not suggest that a doctrinal analysis of “waqf” will be necessary to or

dispositive of a beneficiary determination.

       Likewise, it does not appear that the district court must analyze religious doctrine

to determine whether UIS can sustain a claim against NAIT as trustee. Appellants argue

that the district court will have to interpret “waqf” to determine whether NAIT has fulfilled

its duties as trustee. We are not convinced. A trustee’s secular duties can be evaluated


                                               14
under neutral principles of law without resulting in excessive entanglement, cf. Jones, 443

U.S. at 604, 99 S. Ct. at 3026 (observing that a court must evaluate religious documents

establishing a trust in secular terms), and it does not appear at this point that UIS is basing

its claims on alleged violation of religious duties. To the extent appellants argue that the

use of the term “waqf” in the warranty deeds did not establish NAIT as the trustee in 2009,

we are not persuaded that doctrinal analysis of the term is necessary to determining when

the trust was created.

       The district court determined that it could likely resolve this dispute by relying on

neutral principles of law. Based on the majority of UIS’s allegations, resolution of the

dispute likely requires analysis of (1) the October 30, 2007 meeting minutes;

(2) subsequent documents such as MAAS’s resolution regarding the meeting’s agreement;

(3) the warranty deeds conveying the properties to NAIT; (4) correspondence regarding

which party was intended to be the beneficiary of the trust; (5) the 2012 declaration of trust;

and (6) any relevant testimony. We agree with the district court that determining when a

trust was created and which party was intended to be the trust beneficiary likely involves

neutral principles of law rather than religious doctrine.

       As noted above, however, several of UIS’s assertions raise a concern that UIS could

later rely on evidence regarding religious doctrine to support its petition and civil action.

If UIS does so and the dispute can no longer be resolved under neutral principles of law,

the district court will need to respond accordingly. But because UIS asserts that its

allegations can be analyzed using neutral principles of law and that it does not intend to

introduce evidence regarding religious doctrine, and because the bulk of UIS’s allegations


                                              15
rely upon secular documents, we cannot at this time hold that UIS’s arguments definitely

implicate religious doctrine.6

Interference with an Internal Church Decision

       We similarly cannot hold at this time that a court resolution of this matter would

necessarily interfere with an internal church decision that affects the faith and mission of

the church. See Pfeil, 877 N.W.2d at 534.

       Appellants argue that UIS’s assertions regarding Zubair involve matters of church

discipline, which the district court cannot properly consider. See id. at 541 (holding that

analyzing statements made during a church disciplinary proceeding would improperly

interfere with a church decision regarding faith or mission). But we disagree that UIS’s

allegations regarding Zubair and the alleged removal of Zubair from MAAS’s board are

similar to the allegations and church disciplinary proceeding at issue in Pfeil. Unlike in

Pfeil, a resolution in this case does not require an intrusion into a church decision to

discipline Zubair. See id.

       Appellants also argue in their reply brief that, to resolve the parties’ dispute, the

district court will have to decide whether the Imam has violated Islamic doctrine by how

he chooses to teach Islam to the community and by his decision not to remain neutral in

this dispute. We disagree. Nothing in UIS’s civil action or trust petition suggests that UIS

requests relief based on the Imam’s actions. The Imam’s teachings currently appear

  Appellants note that they also raised doctrinal issues in defense of UIS’s complaint, but
they do not elaborate on how the issues they raised require reversal of the district court’s
ruling.

                                            16
irrelevant to UIS’s claims. In addition, we see no reason at this stage that the district court

would have to decide whether the Imam violated Islamic doctrine by not remaining neutral.

       Finally, appellants argue that, by recognizing the potential of an entanglement issue

and by allowing future analysis of this issue, the district court has already become

excessively entangled with religion. In Pfeil, the appellants sought relief for several

allegedly defamatory statements made in a church disciplinary meeting. Id. at 531. In

deciding the tort claims were barred, the supreme court rejected the appellants’ proposed

“statement-by-statement analysis” because, it held, simply determining whether a

statement is “secular” or “religious” in that context would require interpretation of religious

doctrine. Id. at 538. “[T]his sort of complicated and messy inquiry” itself creates excessive

entanglement with religion. Id. at 538-39. Here, in contrast, it does not appear that

resolution of UIS’s claims in its trust petition and complaint will necessarily require

interpretation of religious doctrine or that religious doctrine must be interpreted simply to

make that determination. The district court recognized that its ability to resolve UIS’s

claims will change if it becomes apparent that resolution requires analysis of the tenets and

beliefs of Islam. That recognition does not run afoul of Pfeil.

       We conclude that it is premature to hold that UIS’s allegations cannot be resolved

under neutral principles of law or that a resolution would improperly interfere with a church

decision. We therefore affirm the district court’s denial of MAAS and NAIT’s summary-

judgment motion on this point.

       Appellants also argue that the arbitration clause in the declaration of trust deprives

the district court of subject-matter jurisdiction over UIS’s lawsuit and that the district court

therefore erred by not granting MAAS and NAIT’s motion for summary judgment. The

district court determined that appellants had waived their arbitration defense.

       As appellants assert, a challenge to the court’s subject-matter jurisdiction “can be

raised at any time and cannot be waived by the parties.” Nelson v. Schlener, 859 N.W.2d

288, 291 (Minn. 2015). But arbitration is an affirmative defense, and failure to invoke

arbitration in an answer results in a waiver of the defense. W. St. Paul Fed’n of Teachers

v. Indep. Sch. Dist. No. 197, 713 N.W.2d 366, 377 (Minn. App. 2006); see Minn. R. Civ.

P. 8.03 (requiring parties to set forth affirmative defenses, including arbitration, in their

answers). “Waiver of a contractual right to arbitration is ordinarily a question of fact and

determination of this question, if supported by substantial evidence, is binding on an

appellate court.” Fedie v. Mid-Century Ins. Co., 631 N.W.2d 815, 819 (Minn. App. 2001)

(quotation omitted), review denied (Minn. Oct. 16, 2001). Findings of fact are not set aside

unless clearly erroneous. Id.

       Appellants argue that the district court erred by not specifically finding that

appellants intentionally relinquished a known right. See id. (explaining that waiver

requires “intent to relinquish a known right”). But the district court discussed appellants’

decisions to (1) not raise the arbitration clause in either their response to the trust petition

or their answer in the civil case, (2) not move to amend either answer, and (3) litigate the

matter for over two years before invoking the provision. Through this discussion, the


                                              18
district court implicitly found that appellants relinquished a known right. See Bros.

Jurewicz, Inc. v. Atari, Inc., 296 N.W.2d 422, 428-29 (Minn. 1980) (affirming the district

court’s conclusion that the appellant waived its right to compel arbitration by filing an

answer and litigating the case in district court for one year before invoking the arbitration

provision). This implicit finding was not clearly erroneous, particularly because the

arbitration clause is located in the declaration of trust, a document that appellants relied on

in both lawsuits.

       Appellants also argue that the caselaw regarding waiver of an arbitration provision

is distinguishable because appellants do not seek to compel arbitration but to defeat the

district court’s subject-matter jurisdiction. But appellants cite no caselaw to support this

distinction. And, on the contrary, we have stated that “[a] contractual agreement to

arbitrate disputes does not strip the district court of its subject matter jurisdiction to resolve

the dispute” when the right to arbitration has been waived. Koes v. Advanced Design, Inc.,

636 N.W.2d 352, 362 (Minn. App. 2001), review denied (Minn. Feb. 19, 2002).

       Appellants argue, though, that the arbitration issue is “particularly important in this

case” because the declaration of trust identifies a “hierarchical tribunal” that could resolve

the property dispute, and the Establishment Clause dictates that a court give deference to a

hierarchal tribunal. Had appellants timely sought to submit UIS’s claims to an arbitration

tribunal at the start of this dispute, their deference argument might be more compelling.

But, as the district court determined, appellants waived their arbitration defense, and

appellants cite no caselaw for the proposition that holding them to that waiver would




                                               19
violate the Establishment Clause. The arbitration provision appears not in a church

document but in a secular agreement, and appellants waived it.

       Because appellants did not invoke the arbitration clause in the declaration of trust

until MAAS and NAIT’s summary-judgment motion, which was filed more than two years

after the start of UIS’s civil action and after extensive litigation in both cases, we conclude

that the district court’s finding that appellants waived their right to invoke the arbitration

clause is not clearly erroneous. We therefore affirm the district court’s denial of MAAS

and NAIT’s motion for summary judgment.
