    ___________________________________
    This appeal involves an Arkansas plaintiff who was involved in an auto accident on a
    bridge between Arkansas and Tennessee with another vehicle operated by an employee of
    the State of Arkansas. The Arkansas plaintiff and her husband filed this personal injury
    suit in the circuit court of Shelby County, Tennessee, naming as defendants the State of
    Arkansas, the Arkansas State Highway and Transportation Department, and the Arkansas
    state employee who was operating the other vehicle. The defendants moved to dismiss
    on numerous grounds, including sovereign immunity and the discretionary principle of
    comity. The Tennessee Attorney General filed an amicus brief on behalf of the
    Tennessee Department of Transportation asking the trial court to extend comity to the
    Arkansas defendants and dismiss the action against them. After two hearings, the trial
    court granted the defendants’ motion to dismiss on the basis of comity. Discerning no
    error, we affirm the decision of the circuit court.

    OPINION
    I.   FACTS & PROCEDURAL HISTORY
    Vicki Mobley and her husband Charles Mobley filed this suit for negligence and
    personal injuries in the circuit court of Shelby County, Tennessee. According to their
    complaint, the Mobleys are citizens and residents of the State of Arkansas. The
    complaint alleges that Mrs. Mobley was driving her vehicle on Interstate 40 across the
    Hernando Desoto Bridge, which spans from Tennessee to Arkansas, when she struck a
    stationary vehicle that belonged to the Arkansas State Highway and Transportation
    Department (and/or the State of Arkansas) and was operated by Arkansas state employee
    Anthony Maurice James. The complaint alleges that the stationary vehicle was parked in
    a lane of travel on the bridge within the geographic boundary of the State of Tennessee
    and that the state employee was apparently repairing signage belonging to the State of
    Arkansas or the Arkansas State Highway and Transportation Department. The complaint
    alleges that the state employee was acting in the course and scope of his employment and
    failed to utilize any warning signs, cones, emergency lighting, or “emergency parts and
    accessories” to warn approaching motorists of his vehicle, nor did he have the signage on
    his truck illuminated. The plaintiffs alleged that the Arkansas state employee was
    negligent or reckless and violated numerous Tennessee statutes, and they sought a
    judgment against the defendants for $1,500,000.
    The Assistant Attorney General for the State of Arkansas filed a motion to dismiss
    on behalf of the three Arkansas defendants. Among other things, the defendants asserted
    that dismissal was proper either because of sovereign immunity or under the discretionary
    principle of comity.1 The defendants submitted documentation reflecting that each of the
    plaintiffs had already filed claims regarding this accident with the Arkansas State Claims
    Commission. They also attached to their motion an “Interagency Memorandum of
    Understanding” between the Tennessee Department of Safety and the Tennessee
    Department of Transportation and the Arkansas State Highway and Transportation
    Department, which, the defendants argued, was meant to address “this exact situation”
    involving a highway incident on the bridge. The stated purpose of the Interagency
    Memorandum was to facilitate joint efforts toward alleviating problems associated with
    roadway incidents and emphasize the urgent and safe clearance of incidents on or around
    the Mississippi River bridges connecting Tennessee and Arkansas. It provided that if an
    agency or employee of one state was sued in the other state for a course of action arising
    from the cooperation of state agencies or employees on or around the bridges, then both
    states would request either dismissal of the out-of-state defendant or application of the
    privileges and immunities of the out-of-state defendant’s home state.

    “‘Comity’ means that courts of one state may, out of respect and the need for interstate
    harmony, defer to the decisions of the courts of another state or extend immunity to another state
    out of deference to the foreign state’s laws, even when not required to do so by the Full Faith and
    Credit Clause of the United States Constitution.” Lemons v. Cloer, 
    206 S.W.3d 60
    , 69 (Tenn. Ct.
    App. 2006).
    -2-
    The Mobleys filed a response in which they argued that Arkansas was not entitled
    to assert sovereign immunity in the courts of its sister states, according to controlling
    United States Supreme Court precedent. Regarding the principle of comity, the plaintiffs
    argued that the trial court should refuse to consider any matters outside the pleadings,
    such as the Interagency Memorandum of Understanding, because the defendants made
    the decision to pursue a motion to dismiss pursuant to Rule 12 of the Tennessee Rules of
    Civil Procedure. However, even if the Interagency Memorandum was considered, the
    Mobleys argued that the complaint did not contain sufficient information about the
    purpose of the state employee’s presence on the bridge in order to determine whether he
    would be covered by the Memorandum. The Mobleys argued that the fact that they were
    Arkansas residents was irrelevant to the jurisdictional issues before the court and asked
    the court to focus on the fact that an Arkansas state employee caused an injury to a
    person inside the State of Tennessee.
    The defendants filed a reply asserting that their Rule 12 motion was brought
    pursuant to Rule 12.02(1), presenting a factual challenge to the trial court’s subject matter
    jurisdiction, and therefore, the trial court could properly consider matters outside the
    pleadings.
    The trial judge held a hearing on the motion to dismiss. The Arkansas Assistant
    Attorney General explained that Arkansas has a Claims Commission and governing
    statutes that are very similar to the system utilized in Tennessee (with the exception that
    Arkansas does not have a cap on damages).2 Noting that the Mobleys had an available
    forum in Arkansas, he asked the trial court to recognize the sovereign immunity of the
    State of Arkansas and dismiss this action based on the principle of comity.
    In response, the Mobleys acknowledged that their claims were still pending before
    the Arkansas State Claims Commission. Still, they maintained that Arkansas was not
    entitled to assert sovereign immunity in the courts of sister states, and they also asked the
    court to decline to recognize its sovereign immunity under the discretionary principle of
    comity. The Mobleys also argued that the Interagency Memorandum was inapplicable by
    its terms based on the facts alleged in the complaint.
    The trial judge noted that the Interagency Memorandum provided that both states
    would request dismissal or ask for application of the privileges and immunities of the out-
    of-state defendant’s home state in the event of litigation. The trial judge raised concerns
    about the implications of her decision for the State of Tennessee in future cases involving
    2
    See Ark. Code Ann. § 19-10-201 (creating the “Arkansas State Claims Commission”).
    The Arkansas State Claims Commission has “exclusive jurisdiction over all claims against the
    State of Arkansas and its several agencies, departments, and institutions.” Ark. Code Ann. § 19-
    10-204(a). It has jurisdiction “over those claims which are barred by the doctrine of sovereign
    immunity from being litigated in a court of general jurisdiction.” 
    Id. § 19-10-204(b)(2)(A).
                                                 -3-
    the Interagency Memorandum. She ultimately decided to defer a decision on the motion
    to dismiss until the Tennessee Attorney General was provided with formal notice of the
    proceeding and given the opportunity to participate.
    After the hearing, the defendants filed a supplemental brief along with additional
    exhibits. The defendants submitted an affidavit from the Arkansas State Highway and
    Transportation Department employee who was driving the vehicle parked on the bridge.
    In the affidavit, the employee stated that on the date of the accident, he received a call
    indicating that a sign was blocking the inside lane of westbound travel on Interstate 40 on
    the Hernando Desoto Bridge. The employee stated that when he arrived on the scene, he
    saw that a construction sign that was bolted to the center median had broken due to a bolt
    coming loose and allowing the sign to swing out into the lane of traffic. He stated that
    the sign posed a real danger because it was essentially debris in the middle of the traffic
    lane hanging at the same level of a car windshield. Based on this affidavit, the
    defendants claimed that the Interagency Memorandum was applicable, as it referenced
    “incidents” such as “crashes, stalled vehicles, debris, special events, [and] road work,”
    and they asked the trial court to dismiss the suit based on the agreement and principles of
    comity.
    The Office of the Tennessee Attorney General and Reporter filed an “amicus
    memorandum” on behalf of the Tennessee Department of Transportation. The Tennessee
    Attorney General took the position that the Interagency Memorandum regarding the
    clearance of roadway incidents on the bridge was applicable to the facts of this case as
    they were described in the affidavit of the Arkansas state employee. The memorandum
    submitted by TDOT states that the loose sign posed “an unanticipated danger” to traffic
    on the bridge that required “a quick response” in order “to prevent potentially disastrous
    consequences.” According to the memorandum, these were the type of circumstances in
    which the states had agreed to cooperate. As a result, TDOT requested that the trial court
    dismiss the lawsuit against the Arkansas defendants. However, TDOT clarified that its
    request was “not merely to conform to the terms of the [Interagency Memorandum],” but
    also under the common law principle of comity. TDOT explained that comity is
    grounded in cooperation and mutuality out of deference and respect to sister states. It
    explained that “Arkansas has adopted a cooperative posture vis-à-vis its sister States” and
    noted that a federal district court in Arkansas had previously extended comity to
    Tennessee in order to promote the harmonious relationship between the two states. See
    Harris v. City of Memphis, 
    119 F. Supp. 2d 893
    (E.D. Ark. 2000). TDOT suggested that
    granting comity to Arkansas in this case would increase the likelihood of Arkansas and
    other sister states extending comity to Tennessee.
    After another hearing, the trial court entered an order granting the Arkansas
    defendants’ motion to dismiss, referencing Tennessee Rule of Civil Procedure 12.02(1).
    The trial court based its dismissal on two alternative grounds—the Interagency
    Memorandum between the states and “the common law principles of comity.” First,
    -4-
    regarding the Interagency Memorandum, the trial court found that it addressed incidents
    on bridges such as stalled vehicles, debris, special events, or road work, and that this
    language encompassed situations like the one presented in this case, which would pose a
    safety hazard and impact traffic flow. As a result, the court found that dismissal was
    appropriate pursuant to the Interagency Memorandum. Alternatively, however, the trial
    court stated that even if the Interagency Memorandum did not exist or apply, dismissal
    was appropriate based on the common law principles of comity. The court noted that
    comity had been extended to the State of Tennessee in the past and that the court did not
    desire to impede the ability of these two states to work together when these situations
    arise. Lastly, the trial court noted that the Mobleys had another forum available in
    Arkansas for the resolution of their claims. For these reasons, the trial court dismissed
    the Mobleys’ lawsuit with prejudice. The Mobleys timely filed a notice of appeal to this
    Court.
    II.     ISSUES PRESENTED
    The parties present the following issues, as we perceive them, for review on
    appeal:
    1.     Whether the Arkansas defendants were entitled to sovereign immunity such that
    the trial court lacked subject matter jurisdiction; and
    2.     Whether the trial court erred in dismissing the case based on the discretionary
    principle of comity.
    For the following reasons, we affirm the decision of the circuit court and remand for
    further proceedings.
    III.   DISCUSSION
    A.    Lack of Jurisdiction due to Sovereign Immunity
    At the outset, we address the Arkansas defendants’ argument that “the doctrine of
    interstate sovereign immunity requires that the lawsuit be dismissed against the State of
    Arkansas and its agents.” According to the Arkansas defendants, “sovereign immunity
    barred the trial court from being able to hear the case based upon principles of the United
    States Constitution as well as common law principles of sovereignty.”
    Subject matter jurisdiction and sovereign immunity “are two different legal
    concepts[.]” Colonial Pipeline Co. v. Morgan, 
    263 S.W.3d 827
    , 851 (Tenn. 2008).
    However, courts may lack subject matter jurisdiction because of the doctrine of sovereign
    immunity. 
    Id. “‘[S]overeign immunity
    is jurisdictional immunity from suit,’” which
    “‘acts as a jurisdictional bar to an action against the state by precluding a court from
    exercising subject-matter jurisdiction.’” 
    Id. (quoting 81A
    Am. Jur. 2d States § 534
    -5-
    (2004)). “The doctrine of sovereign immunity divests the courts of subject matter
    jurisdiction[.]” White v. State ex rel. Armstrong, No. M1999-00713-COA-R3-CV, 
    2001 WL 134601
    , at *3 (Tenn. Ct. App. Feb. 16, 2001). Thus, we treat the Arkansas
    defendants’ motion to dismiss based on sovereign immunity as a challenge to subject
    matter jurisdiction. See Arnold v. Oglesby, No. M2017-00808-COA-R3-CV, 
    2017 WL 5634249
    , at *1 (Tenn. Ct. App. Nov. 22, 2017) perm. app. denied (Tenn. Feb. 14, 2018);
    Smith v. Tenn. Nat’l Guard, 
    387 S.W.3d 570
    , 572 (Tenn. Ct. App. 2012).
    The trial court’s order of dismissal did not expressly analyze the issue of subject
    matter jurisdiction, ruling instead that dismissal was warranted because comity should be
    extended to the Arkansas defendants. Both parties have briefed the issue of sovereign
    immunity as it relates to subject matter jurisdiction on appeal, with the Arkansas
    defendants arguing that jurisdiction does not exist and the Mobleys arguing that it does.
    Because “issues regarding a court’s subject matter jurisdiction should be considered as a
    threshold inquiry,” In re Estate of Trigg, 
    368 S.W.3d 483
    , 489 (Tenn. 2012), we begin
    with consideration of that issue.
    Tennessee courts draw a distinction “between facial and factual challenges to
    subject matter jurisdiction.” Church of God in Christ, Inc. v. L. M. Haley Ministries, Inc.,
    
    531 S.W.3d 146
    , 159 (Tenn. 2017). A facial challenge to subject matter jurisdiction is “a
    challenge to the complaint itself.” Redwing v. Catholic Bishop for Diocese of Memphis,
    
    363 S.W.3d 436
    , 445 (Tenn. 2012). It “asserts that the complaint, considered as a whole,
    fails to allege facts showing that the court has subject matter jurisdiction to hear the
    case.” Church of God in 
    Christ, 531 S.W.3d at 160
    . Accordingly, when evaluating a
    facial challenge, we limit our consideration to the factual allegations of the complaint and
    consider nothing else, utilizing the familiar framework that applies to motions to dismiss
    for failure to state a claim. 
    Id. We simply
    presume that the factual allegations of the
    complaint are true and determine whether those facts establish a basis for the court’s
    exercise of subject matter jurisdiction. 
    Id. A factual
    challenge to subject matter jurisdiction, on the other hand, does not
    attack the allegations of the complaint as insufficient but rather “‘denies that the court
    actually has subject matter jurisdiction as a matter of fact even though the complaint
    alleges facts tending to show jurisdiction.’” 
    Redwing, 363 S.W.3d at 446
    (quoting Staats
    v. McKinnon, 
    206 S.W.3d 532
    , 543 (Tenn. Ct. App. 2006)). It attacks the facts that serve
    as the basis for jurisdiction. 
    Id. When evaluating
    a factual attack, we may consider
    matters outside the pleadings such as affidavits and other documents. Church of God in
    
    Christ, 531 S.W.3d at 160
    . However, “motions challenging subject matter jurisdiction
    are not converted to summary judgment motions when matters outside the pleadings are
    considered or when disputes of material fact exist.” 
    Id. (citing Anderson
    v. Watchtower
    Bible and Tract Soc’y of N.Y., Inc., No. M2004-01066-COA-R9-CV, 
    2007 WL 161035
    ,
    at *32 n.23 (Tenn. Ct. App. Jan. 19, 2007)). The court “must weigh the evidence, resolve
    any factual disputes, and determine whether subject matter jurisdiction exists.” 
    Id. -6- “[T]he
    burden is on the plaintiff to demonstrate that the court has jurisdiction to
    adjudicate the claim.” 
    Redwing, 363 S.W.3d at 445
    . Here, the Arkansas defendants
    moved to dismiss on the basis of sovereign immunity, pointing to the facts that were
    alleged in the complaint—both plaintiffs were citizens of Arkansas, and the three
    defendants were the Arkansas Highway and Transportation Department (described in the
    complaint as a governmental entity of the State of Arkansas), a state employee of the
    Department (also said to be a resident of Arkansas), and the State of Arkansas itself.
    Referencing “[t]he suability of a state,” the defendants asserted that they had not waived
    their right to sovereign immunity and were therefore entitled to dismissal. Essentially,
    the Arkansas defendants asserted that even if the facts alleged in the complaint were true,
    Tennessee’s courts were without subject matter jurisdiction to adjudicate claims against
    them. Accordingly, their challenge to the trial court’s subject matter jurisdiction was
    facial.3 See 
    Redwing, 363 S.W.3d at 445
    -46.
    The landmark decision from the United States Supreme Court addressing the
    sovereign immunity of states in the courts of sister states is Nevada v. Hall, 
    440 U.S. 410
    (1979). In Hall, the plaintiffs were California residents who were injured in an
    automobile accident in California with another driver who was an employee of the
    University of Nevada driving a state-owned vehicle on official business. 
    Id. at 411.
    The
    California plaintiffs filed suit in California and ultimately obtained a judgment against the
    State of Nevada. 
    Id. The United
    States Supreme Court granted certiorari to decide
    whether federal law prohibited California courts from asserting jurisdiction over another
    sovereign State. 
    Id. The Court
    noted that it had not previously addressed the important
    question of “whether a State may claim immunity from suit in the courts of another
    State,” and nothing in the United States Constitution or federal statutes expressly
    answered the question. 
    Id. at 414
    & n.5. Nevada argued that the question was “implicitly
    answered” by the “common understanding” that a sovereign is not amenable to suit
    without its consent. 
    Id. at 414
    . However, the Court proceeded to determine “whether
    that understanding is embodied in the Constitution.” 
    Id. Looking first
    to the source and scope of the traditional doctrine of sovereign
    immunity, the Court explained,
    The doctrine of sovereign immunity is an amalgam of two quite
    different concepts, one applicable to suits in the sovereign’s own courts and
    the other to suits in the courts of another sovereign.
    The immunity of a truly independent sovereign from suit in its own
    courts has been enjoyed as a matter of absolute right for centuries. Only
    the sovereign’s own consent could qualify the absolute character of that
    3
    The documents that were attached to the motion to dismiss were relevant to the
    defendants’ comity argument, which is discussed in the following section of this opinion.
    -7-
    immunity.
    ....
    Mr. Chief Justice Jay described sovereignty as the “right to govern”;
    that kind of right would necessarily encompass the right to determine what
    suits may be brought in the sovereign’s own courts. Thus, Mr. Justice
    Holmes explained sovereign immunity as based “on the logical and
    practical ground that there can be no legal right as against the authority that
    makes the law on which the right depends.”
    This explanation adequately supports the conclusion that no
    sovereign may be sued in its own courts without its consent, but it affords
    no support for a claim of immunity in another sovereign’s courts. Such a
    claim necessarily implicates the power and authority of a second sovereign;
    its source must be found either in an agreement, express or implied,
    between the two sovereigns, or in the voluntary decision of the second to
    respect the dignity of the first as a matter of comity.
    
    Id. at 414
    -416 (footnotes omitted) (emphasis added).
    Next, the Court considered the impact of the sovereign immunity doctrine on the
    framing of the Constitution. 
    Id. at 414
    . The Supreme Court recognized that sovereign
    immunity was “[u]nquestionably . . . a matter of importance in the early days of
    independence” but said that the question of “whether one State might be subject to suit in
    the courts of another State was apparently not a matter of concern when the new
    Constitution was being drafted and ratified.” 
    Id. at 418-19.
    The Court explained that the
    need for constitutional protection against such suits was not discussed, as the framers
    “presumably” had assumed “that prevailing notions of comity would provide adequate
    protection against the unlikely prospect of an attempt by the courts of one State to assert
    jurisdiction over another[.]” 
    Id. at 419.
    After reviewing other aspects of the Constitution in search of a “mandate for
    federal-court enforcement of interstate comity,” the Court found no implication “that any
    one State’s immunity from suit in the courts of another State is anything other than a
    matter of comity.” 
    Id. at 421,
    425. In conclusion, the Court stated,
    In the past, this Court has presumed that the States intended to adopt
    policies of broad comity toward one another. But this presumption
    reflected an understanding of state policy, rather than a constitutional
    command. . . .
    ....
    -8-
    It may be wise policy, as a matter of harmonious interstate relations,
    for States to accord each other immunity or to respect any established limits
    on liability. They are free to do so. But if a federal court were to hold, by
    inference from the structure of our Constitution and nothing else, that
    California is not free in this case to enforce its policy of full compensation,
    that holding would constitute the real intrusion on the sovereignty of the
    States—and the power of the people—in our Union.
    
    Id. at 425-27.
    In their brief on appeal, the Arkansas defendants acknowledge that their claim of
    sovereign immunity was “based on principles of the United States Constitution as well as
    common law principles of sovereignty.” Based on the Supreme Court’s decision in Hall
    addressing these very issues, we reject the Arkansas defendants’ assertion that they were
    entitled to assert sovereign immunity in Tennessee courts. The defendants argue that
    Hall has “waning precedential value” and “has been called into question in recent years,”
    and they suggest that it may be overturned in the near future. However, the fact remains
    that it has not been overturned as of the date of this opinion. See, e.g., Catholic Diocese
    of Arlington Virginia v. Com. Transp. Comm’r, 74 Va. Cir. 154, 
    2007 WL 5961975
    , at*1
    (Va. Cir. Ct. 2007) (“Maryland presents a spirited argument that Nevada v. Hall should
    be overruled. Whatever the merits of that argument—and Maryland may well be right
    that Hall would not come out the same way today as it did in 1979—this Court is bound
    by that decision until the Supreme Court tells it otherwise.”) As the Mobleys aptly noted
    in their reply brief, “If Nevada v. Hall later is overturned, the State of Arkansas [could]
    raise that issue when it becomes an issue; but for now, the law as it is should guide the
    decision in this case.”4
    Next, the Arkansas defendants argue that they were entitled to assert sovereign
    immunity in Tennessee courts based on Tennessee caselaw regarding interstate sovereign
    immunity. For instance, they rely on Tappan v. Western & Atlantic Railroad Co., 
    71 Tenn. 106
    (1879), a case decided by the Tennessee Supreme Court a century before the
    United States Supreme Court decided Hall. In Tappan, the State of Georgia moved to
    dismiss a suit on the basis that “the State of Georgia is one of the Sovereign States of the
    United States of America, and is not liable or subject to be sued, arraigned or impleaded
    in the courts of Tennessee, and therefore insists she is not bound to submit to the
    jurisdiction sought to be exercised.” 
    Id. at 110
    (internal quotation marks omitted). The
    4
    In Franchise Tax Bd. of California v. Hyatt, 
    136 S. Ct. 1277
    , 1279 (2016), the Supreme
    Court was equally divided 4-4 as to whether Nevada v. Hall should be overruled. After the
    decision on remand, the Supreme Court granted another petition for writ of certiorari, 
    138 S. Ct. 2710
    , and the case remains pending before the Court. Indiana and 43 other states have filed a
    brief as amici curiae urging the Court to overturn Nevada v. Hall. 
    2018 WL 4583704
    .
    -9-
    Tennessee Supreme Court affirmed dismissal, stating,
    It is hardly necessary to cite authorities in support of the proposition,
    that a State of this Union, is as to any other State a foreign and independent
    government; whether sovereign in the fullest sense of the term, we do not
    stop to inquire. No State can be sued in its own courts, except by its
    consent, and certainly can not be impleaded in a foreign State, against its
    consent. These are axiomatic principles of jurisprudence, about which there
    can be no doubt or debate.
    
    Id. at 112-13.
    The Tennessee Supreme Court went on to say that it could not hold that
    Georgia could be sued in Tennessee courts “without overturning, or disregarding
    principles long established, and so well-grounded in reason and the philosophy of the
    law, as to be impregnable to attack.” 
    Id. at 113.
    Although the Tennessee Supreme Court did not specify the precise source of these
    unspecified principles, we believe that they were grounded in federal constitutional law
    or the traditional notions of sovereign immunity discussed at length by the United States
    Supreme Court in Hall. As the Supreme Court of Delaware succinctly explained,
    For almost two hundred years, it had been assumed that the United States
    Constitution implicitly prohibited one state from being sued in the courts of
    another state—just as the Eleventh Amendment explicitly prohibited states
    from being sued in federal courts. That implicit assumption was based on
    the theory that interstate immunity was an attribute of state sovereignty that
    had been reserved to the states in the United States Constitution. In 1979,
    when it decided Hall, the United States Supreme Court held that
    assumption was unwarranted.
    Kent Cty., State of Md. v. Shepherd, 
    713 A.2d 290
    , 297 (Del. 1998) (footnotes omitted);
    see also Ann Woolhandler, Interstate Sovereign Immunity, 2006 Sup. Ct. Rev. 249, 252,
    276 (2006) (explaining that “both federal and state courts proceeded on assumptions of
    interstate sovereign immunity for 180 years--until Hall” and noting that the Tennessee
    Supreme Court in Tappan had “manifested the same working assumption as the federal
    courts that constitutional and general law immunity principles prevented states from
    being made involuntary parties in suits in other states”). Notably, the Arkansas
    defendants do not point to any specific aspect of Tennessee law pursuant to which they
    would be entitled to sovereign immunity independent of these sources. As a result, we
    conclude that Hall is controlling as to this issue rather than Tappan.
    Pursuant to the Hall decision, the Arkansas defendants had no absolute right to
    assert sovereign immunity in the courts of this State. Consequently, the trial court did not
    lack subject matter jurisdiction on the basis of sovereign immunity.

    B.   Discretionary Dismissal on the Basis of Comity
    Next, we address the issue of comity, which served as the basis for the trial court’s
    decision to decline to exercise its jurisdiction and instead dismiss the suit against the
    Arkansas defendants.5 In Nevada v. Hall, the Supreme Court stated that a state’s claim of
    immunity in another sovereign’s courts “necessarily implicates the power and authority
    of a second sovereign,” and therefore, “its source must be found either in an agreement,
    express or implied, between the two sovereigns, or in the voluntary decision of the
    second to respect the dignity of the first as a matter of 
    comity.” 440 U.S. at 416
    (emphasis added); see also Alden v. Maine, 
    527 U.S. 706
    , 749 (1999) (“the immunity of
    one sovereign in the courts of another has often depended in part on comity or
    agreement”).
    In the case before us, the Arkansas defendants asserted immunity under both
    options—citing the agreement between the two states expressed in the Interagency
    Memorandum and also seeking comity under common law principles. And, the trial
    court granted the motion to dismiss on both alternative bases, finding the Interagency
    Memorandum applicable, but at the same time, holding that dismissal was appropriate
    under common law principles of comity regardless of the existence or applicability of the
    Interagency Memorandum.
    On appeal, the Mobleys argue that the trial court should not have considered the
    Interagency Memorandum and should not have found it applicable to these facts.
    However, we conclude that dismissal of the Arkansas defendants was proper under
    common law principles of comity based on the allegations of the complaint and do not
    reach the issue of the Interagency Memorandum.
    Even if it is not constitutionally mandated, Tennessee retains the discretion to
    decline to exercise jurisdiction over this suit as a matter of comity. “At bottom, comity is
    about one sovereign respecting the dignity of another.” Michigan v. Bay Mills Indian
    Cmty., 
    572 U.S. 782
    , 817 (2014) (Thomas, J., dissenting). This Court has described
    comity as “the golden rule as applied between states,” meaning that “one state will do in
    regard to the laws of another state that which if the conditions were reversed, it would
    like for the other state to do in regard to its laws.” U.S. Gypsum Co. v. Am. Sur. Co. of
    N.Y., 
    14 Tenn. App. 367
    , 373 (1931). Whether to grant comity in a given situation is
    “purely a question of Tennessee law.” Hyde v. Hyde, 
    562 S.W.2d 194
    , 198 (Tenn. 1978).
    “[C]omity is a discretionary doctrine and may be granted or withheld depending on the
    5
    It is important to “distinguish the concepts of lack of subject matter jurisdiction and
    declining to exercise jurisdiction based on principles of comity.” Levert v. Univ. of Ill. at
    Urbana/Champaign ex rel. Bd. of Trustees, 
    857 So. 2d 611
    , 617 (La. Ct. App. 2003).
    - 11 -
    particular facts, laws and policies present in an individual case.”6 
    Id. However, Tennessee
    courts will not extend comity if it would violate the public policy of this State.
    Id.; see also In re Conservatorship of Clayton, 
    914 S.W.2d 84
    , 92 (Tenn. Ct. App. 1995).
    Again, in Nevada v. Hall, the Supreme Court said that it had historically
    “presumed that the States intended to adopt policies of broad comity toward one another”
    as a matter of state policy. Nevada v. 
    Hall, 440 U.S. at 425
    . The Court added, “It may
    be wise policy, as a matter of harmonious interstate relations, for States to accord each
    other immunity or to respect any established limits on liability. They are free to do so.”
    
    Id. at 426.
    Clearly, the Court “encouraged” but did not compel the states to accord
    deference to each other as a matter of comity. McDonnell v. State of Ill., 
    748 A.2d 1105
    ,
    1106 (N.J. 2000); see also Montaño v. Frezza, 
    393 P.3d 700
    , 703 (N.M. 2017) (“The
    United States Supreme Court has long referred to a broad presumption of comity between
    the states[.]”); Greenwell v. Davis, 
    180 S.W.3d 287
    , 297 (Tex. Ct. App. 2005) (“There is
    a presumption that the sovereign states in the United States intend to adopt a policy of
    broad comity toward one another.”) (internal quotation marks omitted).
    We extended comity to recognize the governmental immunity of the State of
    Georgia in Lemons v. Cloer, 
    206 S.W.3d 60
    , 69 (Tenn. Ct. App. 2006), a case involving a
    Georgia school bus crash just over the Tennessee state line. We said,
    “Comity” means that courts of one state may, out of respect and the
    need for interstate harmony, defer to the decisions of the courts of another
    6
    Some courts hold that the extension of comity is a matter within the discretion of each
    trial judge. See, e.g., 
    Levert, 857 So. 2d at 618
    (La. Ct. App. 2003) (“the decision to extend
    comity rests in the sound discretion of the trial court”); Univ. of Iowa Press v. Urrea, 
    440 S.E.2d 203
    , 204 (Ga. Ct. App. 1993). Others recognize that comity is a discretionary principle but
    review a comity decision on appeal either de novo or under a mixed standard of review. See,
    e.g., Montaño v. Frezza, 
    393 P.3d 700
    , 704 (N.M. 2017) (“We apply a mixed standard of review
    to questions of comity. While a district court’s decision to extend comity in a given case is
    subject to de novo review, we also analyze any fact-intensive aspects of the district court’s
    comity analysis under a more deferential abuse of discretion standard.”); Atl. Coast Conference
    v. Univ. of Maryland, 
    751 S.E.2d 612
    , 618 (N.C. App. 2013) (“while the decision as to whether
    comity should be extended in any given case has been assigned to the discretion of our courts as
    a general matter, it does not follow that our courts should leave each comity decision to the
    sound discretion of the trial judge”); Greenwell v. Davis, 
    180 S.W.3d 287
    , 294-95 (Tex. Ct. App.
    2005) (declining to defer to trial courts’ discretion on matters involving relations between Texas
    and other sovereigns and concluding that a de novo standard of review “rests on a firmer
    foundation”). According to the Texas Court, “‘The discretion in applying comity is a discretion
    of law rather than the discretion of the trial court.’” 
    Id. at 295
    (quoting 16 Am. Jur. 2d Conflicts
    of Laws § 17 (1998)).
    It is not necessary for us to adopt one or the other approach in this case because we would
    affirm the trial court’s decision under either an abuse of discretion or a de novo standard.

    state or extend immunity to another state out of deference to the foreign
    state’s laws, even when not required to do so by the Full Faith and Credit
    Clause of the United States Constitution. See Nevada v. Hall, 
    440 U.S. 410
    , 426, 
    99 S. Ct. 1182
    , 1191, 
    59 L. Ed. 2d 416
    (1979) (“It may be wise
    policy, as a matter of harmonious interstate relations, for States to accord
    each other immunity or to respect any established limits on liability.”).
    “[W]here the law of another jurisdiction is applicable, Tennessee will
    enforce the substantive rights which litigants have under the laws of the
    other jurisdiction if such rights are not contrary to the policy of Tennessee.”
    Hyde v. Hyde, 
    562 S.W.2d 194
    , 196 (Tenn. 1978). The public policy of a
    state is found in its constitution, statutes, and court decisions. 
    Id. In the
           instant case, it is clear that Georgia’s law with respect to waiver of
    immunity is completely in harmony with the public policy of Tennessee.
    
    Id. The Sixth
    Circuit has also observed that “[w]hile Tennessee has no constitutional
    obligation to recognize the sovereign immunity that a sister state may have granted to a
    citizen, see Nevada v. Hall, 
    440 U.S. 410
    , 426–27 [] (1979), Tennessee courts choose to
    do so, in their discretion, in the interest of comity and state harmony.” Town of Smyrna,
    Tenn. v. Mun. Gas Auth. of Ga., 
    723 F.3d 640
    , 647 (6th Cir. 2013) (concluding that
    Tennessee would apply Georgia sovereign immunity law as a matter of comity). Citing
    the Lemons decision, the Sixth Circuit explained that “Tennessee will enforce a sister
    state’s sovereign immunity to a defendant state entity so long as the other state’s rules are
    not ‘contrary to the policy of Tennessee,’ as found in its constitution, statutes, and court
    decisions.” 
    Id. (quoting Lemons,
    206 S.W.3d at 69).
    Finally, we note that a federal district court in the State of Arkansas extended
    comity and immunity to a Tennessee municipality in another case involving an auto
    accident on a bridge between the two states. Harris v. City of Memphis, Tenn., 119 F.
    Supp. 2d 893, 897 (E.D. Ark. 2000). The district court found that Arkansas and
    Tennessee statutes were similar with respect to immunity and observed that “the
    harmonious relationship between the two states would not be enhanced if this Court were
    to ignore the immunity granted under Tennessee law simply because the accident
    occurred a few yards on this side of the state line.” 
    Id. at 896.
    Here, the Mobleys are asking the State of Tennessee to resolve a case involving
    two Arkansas plaintiffs and three Arkansas defendants. In response, the Arkansas
    defendants have asked Tennessee’s courts to recognize their sovereign immunity and
    decline to exercise jurisdiction over this action. The defendants have the better argument
    with respect to this issue. Even though this accident allegedly occurred on “the
    Tennessee side” of the bridge, Tennessee has little interest in litigating this dispute
    involving only Arkansas parties. To use the words from Hall, it would be “wise policy,
    - 13 -
    as a matter of harmonious interstate 
    relations,” 440 U.S. at 426
    , to accord immunity to
    the Arkansas defendants under these circumstances. The common law principles of
    comity dictate that this dispute should be resolved by the available tribunal in Arkansas.
    Sovereignty law in Arkansas is sufficiently aligned with the law in Tennessee such that
    its application does not violate the public policy of Tennessee. Compare 
    Greenwell, 180 S.W.3d at 291
    (Tex. Ct. App. 2005) (“Given the policy of promoting amicable
    relationships by recognizing a sister state’s law, the extent of the difference in the laws is
    not so contrary to Texas public policy that we should refuse to enforce the Arkansas
    law.”) In fact, the only difference in the laws that the parties to this case have mentioned
    is the existence of a damage cap in Tennessee while Arkansas has none.
    We also recognize that Tennessee has an interest in extending immunity by comity
    in order to encourage Arkansas and other states to extend immunity to Tennessee in the
    future. See, e.g., Sam v. Sam, 
    134 P.3d 761
    , 767 (N.M. 2006) (recognizing that “other
    states will likely consider our decisional law on the subject of comity” and “may be
    reluctant to extend immunity to our state if we have previously declined to extend
    immunity to a sister state”); 
    Greenwell, 180 S.W.3d at 292
    (“under the doctrine of
    comity, Texas will recognize the laws of other states with the expectation that those states
    will extend Texas the same consideration”); 
    Levert, 857 So. 2d at 622
    (“By extending
    comity to a sister state, other states will be more likely to honor Louisiana’s sovereign
    immunity laws when litigation arises within their forums in the future.”) We therefore
    affirm the trial court’s decision to decline to exercise its jurisdiction based on the
    principle of comity.
    IV.   CONCLUSION
    For the aforementioned reasons, we affirm the decision of the circuit court. Costs
    of this appeal are taxed to the appellants, Vicki and Charles Mobley, for which execution
    may issue if necessary.
