  •               IN THE SUPREME COURT OF IOWA
    No. 80 / 04–1655
    Filed August 29, 2008
    PAMELA SUE HOOK,
    Appellee,
    vs.
    CARL FREDERICK LIPPOLT and the STATE OF IOWA,
    Appellants.
    Appeal from the Iowa District Court for Webster County, Ronald H.
    Schechtman, Judge.
    On interlocutory appeal from district court’s ruling denying
    summary judgment to defendants, defendants argue plaintiff’s claim was
    subject to dismissal on statute-of-limitations grounds. REVERSED AND
    REMANDED.
    Thomas J. Miller, Attorney General, and Joanne Moeller and Mark
    Hunacek, Assistant Attorneys General, for appellants.
    Tito Trevino of Trevino Law Offices, Fort Dodge, for appellee.

    TERNUS, Chief Justice.
    The appellee, Pamela Hook, brought suit for injuries she sustained
    in an automobile accident caused by appellant Carl Lippolt, who at the
    time of the accident was working as a volunteer for the Department of
    Human Services.     After dismissing her initial lawsuit against Lippolt,
    Hook filed the present action against Lippolt and the State under the
    State Tort Claims Act. See Iowa Code ch. 669 (1999). Both defendants
    asserted a statute-of-limitations defense, and Lippolt claimed statutory
    immunity. See 
    id. §§ 669.13,
    .24. The district court denied motions for
    summary judgment filed by the defendants, rejecting their argument that
    the plaintiff failed to file her claim with the state appeal board within the
    time limits established by the governing statute of limitations and
    rejecting Lippolt’s claim of statutory immunity.           On appeal, the
    defendants assert the district court erred because the plaintiff discovered
    her cause of action more than two years before filing her administrative
    claim, and therefore, this suit is barred. The defendants also argue there
    is no evidence to support the plaintiff’s claim the defendants are
    equitably estopped from relying on the statute-of-limitations defense
    under the doctrine of fraudulent concealment. Finally, Lippolt contends
    he enjoys immunity from suit as a matter of law.
    Upon our review of the record and the parties’ arguments, we
    conclude there is no genuine issue of material fact with respect to
    Lippolt’s entitlement to immunity, and therefore, his summary judgment
    motion on the plaintiff’s negligence claim should have been granted.
    With respect to the parties’ statute-of-limitations defense, we conclude as
    a matter of law the plaintiff’s claim was untimely and the defendants are
    not equitably estopped from relying on the statute of limitations as a
    defense.   The district court erred in failing to rule the plaintiff’s
    3
    negligence claim is barred. Accordingly, we reverse the district court’s
    ruling and remand this case for entry of judgment in favor of the
    defendants on the negligence count of plaintiff’s petition.
    I. Background Facts and Proceedings.
    On June 9, 2000, Pamela Hook and Carl Lippolt were involved in a
    car accident when Lippolt entered an intersection on a red light and
    struck Hook’s vehicle. Hook was injured in the accident. Lippolt, who
    was seventy-eight years old, admitted from the beginning that the
    collision was his fault.          Following the accident, Lippolt’s personal
    automobile insurance carrier settled Hook’s property damage claim, but
    no   agreement      could    be   reached      on   her   personal     injury   claim.
    Consequently, on March 13, 2002, Hook filed suit against Lippolt.
    In July 2002, more than two years after the accident, Hook
    propounded interrogatories to Lippolt. Lippolt revealed in his answers
    that, at the time of the accident, he was using his own vehicle to provide
    transportation services for a client of the Department of Human Services
    (DHS) as a volunteer for the department.1 The preparation and service of
    Lippolt’s interrogatory answers was the first time Hook, Hook’s attorney,
    and Lippolt’s attorney were aware of these facts. Thereafter, Lippolt was
    permitted to amend his answer to assert an immunity defense under
    chapter 669.      See 
    id. § 669.24
    (providing for immunity from personal
    liability for persons performing voluntary services for a state agency).
    Lippolt was also allowed to add an affirmative defense based on Hook’s
    failure to submit her claim to the state appeal board within two years of
    the accident.     See 
    id. § 669.13
    (requiring claim against state or state
    1The  plaintiff asked the following interrogatory: “State whether you were acting
    within the course and scope of any agency, employment, or service at the time of the
    collision and describe the type of relationship of the persons involved.”
    4
    employee be first presented to state appeal board within two years of
    accrual or be “forever barred”).       In July 2003, Hook filed a dismissal
    without prejudice of her lawsuit against Lippolt. She did not appeal the
    district court’s ruling allowing Lippolt to assert the immunity and
    statute-of-limitations defenses.
    Nearly three years after the accident, on June 3, 2003, Hook filed
    an   administrative     claim   with    the   state   appeal    board   seeking
    compensation for her personal injury. After six months passed with no
    response from the board, Hook withdrew her claim and commenced the
    current lawsuit against Lippolt and the State on January 27, 2004. See
    
    id. § 669.5
    (stating that after six months with no response from the
    board, claimant may withdraw claim from board’s consideration and file
    suit).    Hook made two claims in her petition:        (1) a negligence claim
    against both defendants for the damages she sustained in the June 9,
    2000 accident; and (2) a fraudulent misrepresentation claim against
    Lippolt based on representations he made to the plaintiff from April 8,
    2002, to May 21, 2003, in the first lawsuit.          With respect to Hook’s
    negligence claim, the defendants asserted a statute-of-limitations defense
    in their answers. Lippolt also claimed statutory immunity under section
    669.24.
    Lippolt filed a motion for partial summary judgment, seeking
    summary judgment on Hook’s negligence claim.                   He asserted his
    immunity and statute-of-limitations defenses should be decided in his
    favor as a matter of law. The State subsequently filed its own motion for
    summary judgment based on the statute of limitations. The plaintiff also
    filed a motion for partial summary judgment claiming the statute of
    limitations had been tolled by the discovery rule and asking the court to
    rule as a matter of law that her administrative claim was timely filed.
    5
    Although Hook did not contest the fact that Lippolt’s “personal assets
    [were immune] from attachment or execution to satisfy any judgment,”
    she claimed he was a proper defendant for two reasons.               Because the
    State would be required to defend and indemnify Lippolt under section
    669.21, Hook reasoned that statute anticipates that even volunteers not
    personally liable are still proper parties in an action against the State. In
    addition, Hook asserted Lippolt’s personal liability insurance policy was
    available to satisfy any judgment by virtue of section 669.20,2 and
    therefore, it was necessary to include Lippolt as a defendant.
    In ruling on these various motions, the district court concluded as
    a matter of law that the plaintiff had neither actual nor imputed
    knowledge of her cause of action more than two years prior to filing her
    administrative claim.       Therefore, the court sustained the plaintiff’s
    motion for partial summary judgment on the defendants’ statute-of-
    limitations defense and overruled the defendants’ summary judgment
    motions on this issue. With respect to the immunity issue, the district
    court ruled that Lippolt was not personally liable and section 669.20 did
    not make Lippolt’s insurer liable. Although the court overruled Hook’s
    motion for partial summary judgment on the insurance issue, the court
    denied, for unexplained reasons, Lippolt’s motion for partial summary
    judgment on his immunity defense.                We granted the defendants’
    application for interlocutory appeal to review the district court’s
    summary judgment rulings.
    2Iowa Code section 669.20 states in pertinent part: “Whenever a claim or suit
    against the state is covered by liability insurance, the provisions of the liability
    insurance policy on defense and settlement shall be applicable notwithstanding any
    inconsistent provisions of this chapter.”
    6
    II. Scope of Review.
    Summary judgment rulings are reviewed for correction of errors of
    law. Hallett Constr. Co. v. Meister, 
    713 N.W.2d 225
    , 229 (Iowa 2006). “To
    obtain a grant of summary judgment on some issue in an action, the
    moving party must affirmatively establish the existence of undisputed
    facts entitling that party to a particular result under controlling law.”
    Interstate Power Co. v. Ins. Co. of N. Am., 
    603 N.W.2d 751
    , 756 (Iowa
    1999).
    III. Lippolt’s Immunity.
    We begin our review by considering the district court’s ruling
    denying Lippolt’s motion for partial summary judgment on Hook’s
    negligence claim based on Lippolt’s immunity defense under section
    669.24.
    A. Statutory Provisions. At the time of the events giving rise to
    this lawsuit, chapter 669 required that “any claim as defined in this
    chapter” be submitted to the state appeal board for disposition.        Iowa
    Code §§ 669.3, .5.      Section 669.2(3) defines “claim” to include “[a]ny
    claim against an employee of the state for money only . . . on account of
    personal injury or death, caused by the negligent or wrongful act or
    omission of any state employee while acting within the scope of the
    employee’s office or employment.” 
    Id. § 669.2(3)(b).
    An “employee of the
    state” is broadly defined to include
    agents . . . of the state or any state agency . . . and persons
    acting on behalf of the state or any state agency in any
    official capacity, temporarily or permanently in the service of
    the state of Iowa, whether with or without compensation . . . .
    
    Id. § 669.2(4)
    (emphasis added). It is important to keep in mind that the
    term “employee” as used in chapter 669 includes unpaid volunteers as
    well as paid workers.
    7
    We turn now to the indemnity and immunity provisions of this
    statute. At the outset, it is helpful to note the distinction between a right
    to be defended and indemnified by the State and immunity—the absence
    of personal liability. See Dickerson v. Mertz, 
    547 N.W.2d 208
    , 213 (Iowa
    1996) (referring to statute providing that state employees “are not
    personally liable” for certain claims as granting such employees
    immunity).      Chapter    669’s    indemnity    provision   is   found   in
    section 669.21, which provides that the State will defend and indemnify
    “any employee” against claims falling within chapter 669, subject to
    exceptions not pertinent to this case. Iowa Code § 669.21.
    Chapter 669 contains two immunity provisions, one covering all
    employees and one applicable to volunteers. See 
    id. §§ 669.23,
    .24. All
    employees are granted immunity for exempted claims, i.e., claims that do
    not fall within the State Tort Claims Act.        See Iowa Code § 669.23
    (“Employees of the state are not personally liable for any claim which is
    exempted under section 669.14.”); see also 
    id. § 669.14
    (exempting
    specified claims from the provisions of the State Tort Claims Act). Hook’s
    claim is not exempted under section 669.14, so the immunity provided to
    employees by section 669.23 does not protect Lippolt from personal
    liability for Hook’s damages.
    Lippolt’s immunity defense is based on section 669.24, which
    grants broader immunity to volunteers:
    A person who performs services for the state
    government or any agency or subdivision of state
    government and who does not receive compensation is not
    personally liable for a claim based upon an act or omission
    of the person performed in the discharge of the person’s
    duties, except for acts or omissions which involve intentional
    misconduct or knowing violation of the law, or for a
    transaction from which the person derives an improper
    personal benefit.        For purposes of this section,
    8
    “compensation” does not include payments to reimburse a
    person for expenses.
    
    Id. § 669.24.
    It is the applicability of this provision that is at issue here.
    B. Parties’ Contentions.             Although conceding Lippolt provided
    services to DHS without compensation, Hook seems to argue Lippolt
    cannot benefit from the immunity of section 669.24 due to a related
    statute governing DHS volunteers. Iowa Code section 217.13(3) states:
    “All   volunteers     registered     with    [DHS]     and    in    compliance      with
    departmental rules are considered state employees for purposes of
    chapter 669.”3        It appears the plaintiff contends that, if Lippolt is
    considered an employee for purposes of chapter 669, he would not enjoy
    the protection from personal liability provided by section 669.24 to
    volunteers. Lippolt responds that the legislature surely did not intend to
    deprive DHS volunteers of the immunity available to other state
    volunteers.
    C. Discussion.        We conclude Hook’s argument rests on a faulty
    premise:      that the terms “employee” and “volunteer” are mutually
    exclusive under chapter 669. As noted earlier, section 669.2(4) defines
    “employee” broadly to include volunteers.              Consequently, the fact that
    Lippolt may be classified by section 217.13(3) as a state employee for
    purposes of chapter 669 does not preclude him from also qualifying as a
    volunteer for purposes of that chapter.              We believe that, rather than
    intending to deprive DHS volunteers of immunity under section 669.24
    by its enactment of section 217.13(3), the legislature intended to assume
    responsibility under chapter 669 for the torts of persons purporting to
    3
    Hook does not assert there is any genuine issue of material fact with respect to
    whether Lippolt was registered with DHS and in compliance with departmental rules.
    Therefore we accept, as do the parties, that Lippolt satisfies the requirements of section
    217.13(3) so as to qualify as a “state employee[] for purposes of chapter 669.”
    9
    act for DHS only if such persons were registered with DHS and in
    compliance with departmental rules.
    Hook argues that, even if Lippolt is immune under section 669.24,
    he may still be sued for negligence in this lawsuit. We disagree. Section
    669.24 states that a volunteer “is not personally liable.” 
    Id. § 669.24.
    If
    Lippolt is not liable, there is no legal basis to support Hook’s negligence
    suit against Lippolt.       For the same reason, Hook’s claim that she is
    entitled to sue Lippolt to reach his personal liability insurance must fail.
    The ability to sue an individual for damages depends not on the
    individual’s purchase of insurance, but on his liability under the law, a
    liability Lippolt does not have.
    As a final matter, Hook argues the legislature must have
    contemplated suit against immune tortfeasors because such tortfeasors
    are included within the defense and indemnity provisions of section
    669.21, and therefore, she concludes, immune volunteers are subject to
    suit. To the extent Hook’s initial premise is accurate, it does not support
    her conclusion.        Ironically, this lawsuit illustrates why the legislature
    would    extend    a     defense   and    indemnity    to     immune   volunteers.
    Notwithstanding Lippolt’s immunity from personal liability, he has been
    required to defend this action.           Thus, he has benefited from section
    669.21     under   circumstances         not   inconsistent   with   his   personal
    immunity from suit under section 669.24.
    For the foregoing reasons, we conclude Lippolt was entitled to
    summary judgment on Hook’s negligence claim based on his statutory
    immunity.      We now discuss the defendants’ statute-of-limitations
    defense.
    10
    IV. Statute of Limitations—the Discovery Rule.
    The governing statute of limitations is contained in Iowa Code
    section 669.13, which provides in relevant part:
    Every claim and suit permitted under this chapter
    shall be forever barred, unless within two years after such
    claim accrued, the claim is made in writing to the state
    appeal board under this chapter. The time to begin a suit
    under this chapter shall be extended for a period of six
    months from the date of mailing notice to the claimant by
    the state appeal board as to the final disposition of the claim
    or from the date of withdrawal of the claim from the state
    appeal board under section 669.5, if the time to begin suit
    would otherwise expire before the end of such period.
    ....
    This section is the only statute of           limitations
    applicable to claims as defined in this chapter.
    
    Id. § 669.13.
    We have previously held the discovery rule is applicable to
    a state tort claim under chapter 669. See Callahan v. State, 
    464 N.W.2d 268
    , 272 (Iowa 1990).       Under the discovery rule, “the statute of
    limitations does not begin to run until the injured person has actual or
    imputed knowledge of all the elements of the cause of action.” Franzen v.
    Deere & Co., 
    377 N.W.2d 660
    , 662 (Iowa 1985). With respect to imputed
    knowledge, we have said:
    In addition, the person is charged with knowing on the
    date of the accident what a reasonable investigation would
    have disclosed. The period of limitations is the outer time
    limit for making the investigation and bringing the action.
    The period begins at the time the person is on inquiry notice:
    [L]imitations begin to run when a claimant
    gains knowledge sufficient to put [the claimant]
    on inquiry. As of that date, [the claimant] is
    charged with knowledge of facts that would have
    been disclosed by a reasonably diligent
    investigation. The beginning of limitations is not
    postponed until the end of an additional period
    deemed reasonable for making the investigation.
    11
    
    Franzen, 377 N.W.2d at 662
    (quoting Lutheran Hosp. v. Levy, 
    482 A.2d 23
    , 27 (Md. Ct. Spec. App. 1984)) (emphasis added); accord Kendall/Hunt
    Publ’g Co. v. Rowe, 
    424 N.W.2d 235
    , 243 (Iowa 1988) (“[T]he limitations
    period begins when a claimant has knowledge sufficient to put that
    person on inquiry notice.”).
    Based on these principles, the initial step in our analysis is to
    determine whether the undisputed facts establish as a matter of law
    when Hook had actual knowledge of the elements of her claims against
    Lippolt and the State or when she knew enough to be charged with a
    duty to inquire.   If we conclude Hook had enough knowledge to be
    charged with a duty to investigate more than two years prior to filing this
    suit, we must then examine whether, as a matter of law, a reasonably
    diligent investigation would have disclosed the elements of her claims. If
    a reasonably diligent investigation would have disclosed the elements of
    her claims against Lippolt and the State, she is charged with that
    knowledge as of the date her duty to investigate arose.
    A. Discovery of Claim Against Lippolt.           Although we have
    already determined that Lippolt has no personal liability for Hook’s
    negligence claim, it is helpful to our analysis of the State’s statute-of-
    limitations defense to begin with a review of Hook’s discovery of her claim
    against Lippolt. It is undisputed that, on June 9, 2000, Hook knew the
    automobile she was driving was hit by a car driven by Lippolt when he
    entered an intersection against a red light. Hook also knew immediately
    that she was injured and that her car was damaged.         Lippolt did not
    deny that he was at fault for the accident. There is no question under
    the undisputed facts in the record that Hook had actual knowledge of all
    the elements of her claim against Lippolt immediately after the June 9,
    12
    2000 accident, substantially more than two years before she filed her
    claim with the state appeal board on June 3, 2003.
    It is true that Hook did not know within two years of the accident
    that Lippolt was acting as a state volunteer at the time of the collision.
    Knowledge of Lippolt’s volunteer status was not required, however, in
    order to commence the statute of limitations because that fact was not
    an element of Hook’s claim. See 
    Franzen, 377 N.W.2d at 662
    (requiring
    “actual or imputed knowledge of all the elements of the cause of action”
    (emphasis added)).   Lippolt’s volunteer status simply triggered special
    prerequisites for filing suit against Lippolt. Hook had the statutory two-
    year period to determine the appropriate legal channels through which to
    pursue her claim.
    We conclude as a matter of law Hook’s claim against Lippolt
    accrued on June 9, 2000. Because she did not file her administrative
    claim against Lippolt within two years, Hook’s claim against Lippolt is
    barred unless Lippolt is equitably estopped from asserting the statute as
    a defense, a question we address later in this opinion.
    B. Discovery of Claim Against State. As we have discussed,
    Hook had actual knowledge of her injury and that it was caused by
    Lippolt’s negligence on the date of the accident. She did not have actual
    knowledge that the State was vicariously liable for Lippolt’s conduct until
    more than two years later. The State claims, however, that Hook had
    imputed knowledge of that fact as of June 9, 2000, under the concept of
    inquiry notice, and consequently, the limitations period against the State
    commenced on the date of the accident.
    The plaintiff does not dispute that she had actual knowledge of her
    claim against Lippolt immediately after the accident, but she disagrees
    that she was on inquiry notice of her claim against the State based upon
    13
    this knowledge.      Hook claims she had no duty to pursue any
    investigation because she had no reason to “explore[] whether Lippolt
    was really liable” or to “question whether [Lippolt] had immunity.” But
    the issue before us with respect to Hook’s discovery of her claim against
    the State is not Lippolt’s liability or his immunity. The pertinent issue is
    whether an injured person has a duty to investigate who might be liable
    for her injuries. It was the district court’s failure to make this critical
    distinction—between     Lippolt’s   claimed   immunity      and   the   State’s
    liability—that led the district court to erroneously conclude Hook was not
    on inquiry notice. The district court reasoned that, until Hook had some
    basis to believe Lippolt was immune, she had no duty to investigate a
    possible vicarious liability claim against a third party.
    We think Lippolt’s immunity is a red herring and has little to do
    with an injured party’s duty to undertake a reasonably diligent
    investigation of the nature and extent of her legal rights to recover for an
    injury.   See Zeleznik v. United States, 
    770 F.2d 20
    , 23 (3d Cir. 1985)
    (“Once the injured party is put on notice, the burden is upon him to
    determine within the limitations period whether any party may be liable
    to him.”); see also Buechel v. Five Star Quality Care, Inc., 
    745 N.W.2d 732
    , 736 (Iowa 2008) (“Once a person is aware that a problem exists, the
    person has a duty to investigate.”).       Under many circumstances, a
    tortfeasor remains personally liable even though a third party might have
    vicarious liability, as in the situation of employee/employer or vehicle
    operator/vehicle owner.     If a duty to investigate the existence of a
    vicariously liable defendant did not arise until the injured party
    discovered the tortfeasor’s immunity, the statute of limitations would
    never commence against a vicariously liable defendant in cases in which
    the tortfeasor is not immune. We think an injured party who knows of
    14
    her injury and its cause must conduct a reasonable investigation of the
    nature and extent of her legal rights that includes inquiry into the
    identity of any vicariously liable parties. An injured party’s duty to
    investigate the identity of persons liable for her injury is not a seriatim
    process that stops upon the discovery of one defendant and arises again
    only when that defendant’s liability is questioned.
    In a case brought under the Federal Tort Claims Act (FTCA), the
    Fourth Circuit Court of Appeals held plaintiffs who knew the injury to
    their decedent, the cause of the injury, and the identity of the tortfeasors,
    but not that the tortfeasors were federal employees, were on inquiry
    notice of their claim against the government, stating commencement of
    the statute of limitations under the FTCA “does not wait until a plaintiff
    is aware that an alleged tort-feasor is a federal employee.” Gould v. U.S.
    Dep’t of Health & Human Servs., 
    905 F.2d 738
    , 745 (4th Cir. 1990). The
    court stated:
    Plaintiffs’ construction of the limitations statute would
    obviate the necessity of due diligence, even when the injury
    and its cause are known and a minimum inquiry would have
    led plaintiffs to discover in a timely manner the employment
    status of the [tortfeasors]. This approach would remove
    incentives for the timely investigation and prompt
    presentation of claims and would enable a plaintiff to
    maintain a FTCA action against the government years after
    plaintiff’s injury and its cause are well known if, for any
    reason, it escaped the plaintiff’s attention—even absent
    reasonable investigation—that the alleged tort-feasor was a
    government agent acting within the scope of his employment.
    An open-ended rule would vitiate the very purpose of the
    statute of limitations.
    
    Id. at 746.
    A Maryland court reached a similar conclusion in Conaway v.
    State, 
    600 A.2d 1133
    (Md. Ct. Spec. App. 1992).           In Conaway, the
    plaintiff sued the state for allegedly negligent treatment he received while
    15
    a prisoner at a state 
    institution. 600 A.2d at 1134
    .      Although the
    plaintiff filed a timely claim against the state under the Maryland Tort
    Claims Act, he did not learn the identity of the private entity providing
    health care at the state prison—Frank Basil, Inc.—until the time for filing
    a claim had expired.    
    Id. He then
    amended his complaint to assert a
    claim against Basil, but that claim was dismissed on statute-of-
    limitations grounds.   
    Id. at 1134,
    1142.    The Maryland appeals court
    upheld Basil’s dismissal, rejecting the plaintiff’s argument his claim was
    saved by the discovery rule: “We hold that appellant was aware of the
    circumstances surrounding his claim no later than September 8, 1986,
    and that he had three years from that date to bring suit against the
    proper parties.” 
    Id. at 1141–42;
    accord Brown v. Drake-Willock Int’l, Ltd.,
    
    530 N.W.2d 510
    , 513 (Mich. Ct. App. 1995) (“Our courts consistently
    have held that the statute of limitations is not tolled pending discovery of
    the identity of the parties where all the elements of the cause of action
    exist.”).
    Here, Hook knew she had been injured and knew who caused her
    injury. Therefore, she was on inquiry notice and had “a duty to make a
    reasonable investigation” to ascertain the exact parameters of her claim.
    Kendall/Hunt Publ’g 
    Co., 424 N.W.2d at 243
    –44. It cannot be disputed
    that, had Hook inquired to ascertain whether there were any entities or
    persons other than Lippolt that might be liable for her damages, she
    would have discovered Lippolt’s volunteer status and the relationship
    between Lippolt and the State.     Indeed, it took only one interrogatory
    propounded during discovery to reveal the State’s vicarious liability.
    In summary, Hook knew of her injuries and Lippolt’s fault in
    causing those injuries on June 9, 2000. As of that date, the plaintiff had
    a duty to investigate the identity of any party that might be vicariously
    16
    liable for Lippolt’s negligence. As a matter of law, a reasonably diligent
    inquiry would have led to discovery of the State’s liability. Consequently,
    under the doctrine of inquiry notice, Hook is charged with knowledge of
    her claim against the State on June 9, 2000, and accordingly, her claim
    against the State accrued on that date.           Because Hook filed her
    administrative claim nearly three years later, rather than within two
    years of its accrual as required by section 669.13, this lawsuit is barred
    unless the defendants are estopped from relying on their statute-of-
    limitations defense, an issue we now address.
    V. Fraudulent Concealment.
    The plaintiff argues that, even if her administrative claim was not
    timely filed, the defendants are estopped from asserting the statute of
    limitations as a defense under the doctrine of fraudulent concealment.
    The district court did not address this issue, as it concluded Hook was
    not on inquiry notice.      Because we have concluded the statute of
    limitations had expired as a matter of law prior to the commencement of
    this suit, we now consider whether the defendants are estopped from
    asserting the statute of limitations as a bar to this action.
    To establish equitable estoppel, the plaintiff must prove by clear
    and convincing evidence:
    (1) The defendant has made a false representation or has
    concealed material facts; (2) the plaintiff lacks knowledge of
    the true facts; (3) the defendant intended the plaintiff to act
    upon such representations; and (4) the plaintiff did in fact
    rely upon such representations to his prejudice.

    Laval, Inc., 
    454 N.W.2d 576
    , 578–79 (Iowa 1990)); accord Dierking v.
    Bellas Hess Superstore, Inc., 
    258 N.W.2d 312
    , 315 (Iowa 1977).          “This
    doctrine is intended to prevent a party from benefiting from ‘the
    17
    protection of a limitations statute when by his own fraud he has
    prevented the other party from seeking redress within the period of
    limitations.’ ” 
    Christy, 692 N.W.2d at 702
    (quoting Borderlon v. Peck, 
    661 S.W.2d 907
    , 909 (Tex. 1983)).
    Hook   claims   “Lippolt,   through   his   attorneys,   made   false
    representations or concealed the material fact that he was a state
    volunteer” at the time of the accident.      “Conduct amounting to false
    representation or concealment needs to be deceptive or fraudulent.”
    
    Meier, 454 N.W.2d at 580
    . To establish deceptive or fraudulent conduct,
    there must be proof the defendant acted “with the intent to mislead the
    injured party.” Id.; accord 
    Dierking, 258 N.W.2d at 316
    (requiring proof
    defendant “knowingly took a position with the intention that it be acted
    upon”); see also Bensman v. United States Forest Serv., 
    408 F.3d 945
    ,
    965 (7th Cir. 2005) (equitable estoppel requires a showing the defendant
    “engaged in affirmative misconduct rather than mere negligence”).
    In Dierking, the defendant’s insurer unintentionally wrote an
    incorrect injury date on a proposed release and check given to the
    injured plaintiff during the two-year limitations 
    period. 258 N.W.2d at 314
    .   Subsequently, the plaintiff and her attorney relied on the injury
    date stated by the insurer in filing suit more than two years after the
    plaintiff’s cause of action accrued. 
    Id. This court
    held the plaintiff and
    her husband, who had filed a claim for loss of consortium, had not
    established the intent element of equitable estoppel because the insurer’s
    error was unintentional:    “[The plaintiffs] failed, however, to show any
    conduct or words from which can be implied an intent on the part of
    defendant or its insurer to induce plaintiffs to rely to their prejudice on
    those incorrect dates in determining the date of Mrs. Dierking’s injury for
    purposes of the statute of limitations.” 
    Id. at 316.
    We ruled as a matter
    18
    of law that the plaintiffs’ claim was barred by the statute of limitations.
    
    Id. at 317;
    see also 
    Meier, 454 N.W.2d at 580
    (holding claim of equitable
    estoppel should not have been submitted to jury because there was no
    proof the defendant intended by its conduct or assertions to mislead the
    plaintiffs so they would not timely file suit).
    Having reviewed the summary judgment record in this case, we
    reach the same conclusion here. Assuming for the moment that Lippolt’s
    admission of fault or his insurer’s payment of Hook’s property damage
    claim constitute an affirmative act by Lippolt or the State to conceal
    Lippolt’s volunteer status or Hook’s claim against the State, there is no
    evidence either defendant intended to conceal these facts or to induce the
    plaintiff to forgo investigation into the existence of additional defendants.
    The evidence shows Lippolt attached no importance to his volunteer
    status and did not mention the purpose of his trip to his own attorney
    until answering the plaintiff’s interrogatories more than two years after
    the accident. Lippolt did not realize until after the statute of limitations
    had expired that, because he was a department volunteer, the State Tort
    Claims Act was applicable to Hook’s claim and the State was vicariously
    liable.     Lippolt could hardly have intended to conceal Hook’s claim
    against the State when he was unaware such a claim even existed.
    Similarly, the State itself did nothing to affirmatively mislead Hook or
    conceal her claim against the State, as the State had no notice of the
    accident and no contact with Hook until after the limitations period had
    run.4
    4Hook also complains of conduct by Lippolt’s attorney that occurred after the
    two-year statute of limitations had expired. This conduct cannot be a basis to estop the
    defendants from relying on the statute of limitations, however, because by the time this
    conduct occurred, Hook had already missed the filing deadline. See Temple v. Gorman,
    
    201 F. Supp. 2d 1238
    , 1242 (S.D. Fla. 2002) (holding defendants’ conduct after the
    statute of limitations expired “is irrelevant” to claim of equitable estoppel); Merrill v. W.
    19
    A federal district court has rejected a claim of estoppel under
    similar facts.     See Baker v. United States, 
    341 F. Supp. 494
    (D. Md.
    1972). In Baker, the plaintiff was injured in a car accident with Smith, a
    federal 
    employee. 341 F. Supp. at 495
    .          Smith notified his personal
    insurer of the accident, and that insurer investigated the matter and
    communicated with the attorney representing the injured parties until it
    went into receivership.       
    Id. Thereafter, Smith
    settled with one injured
    party, paying his own money. 
    Id. No one
    connected with the matter—
    parties, attorneys or insurer—realized that Smith was acting within the
    scope of his employment at the time of the accident. 
    Id. Smith did
    not
    even report the accident to the government. 
    Id. Eventually, Baker
    filed
    suit against Smith and only then, after the statute of limitations had
    expired, did Smith first learn that he was considered to be within the
    scope of his employment at the time of the accident.                   
    Id. The court
    thereafter granted summary judgment to the defendants on the basis of
    the statute of limitations.       
    Id. at 496.
        Noting that result might seem
    “unfair, since no one realized until too late that Smith was in the course
    of his employment by the government at the time of the accident,” the
    court nonetheless concluded “no facts which would ordinarily amount to
    an estoppel against Smith, his insurer or the government have been
    shown.” 
    Id. Finally, Hook
    contends Lippolt’s insurer and attorney had a duty
    to investigate the circumstances of the accident and a duty to disclose to
    her that Lippolt was acting as a volunteer for the State.                    As we have
    discussed above, the duty of investigation was on Hook, not Lippolt. See
    Va. Dep’t of Health & Human Res., 
    632 S.E.2d 307
    , 318 (W. Va. 2006) (holding
    department’s delay in producing records requested by plaintiff was irrelevant to claim of
    fraudulent concealment in view of fact statute of limitations had expired before records
    were requested).

    employment status of the tort-feasor and to bring suit within the

    , 1022 (Md. Ct. Spec. App. 2004), aff’d, 
    872 A.2d 1
    , 10 (Md. 2005)
    (same).   Additionally, a party’s silence cannot provide the basis for
    estoppel “absent a special duty to disclose.”     Martinelle v. Bridgeport
    Roman Catholic Diocesan Corp., 
    196 F.3d 409
    , 424 (2d Cir. 1999); accord
    Alcorn v. Linke,

    , 641,

    , 96 (1965) (“ ‘Estoppel
    may arise from silence, as well as words, where there is a duty to speak,
    and the party on whom the duty rests has an opportunity to speak, and,
    knowing the circumstances, keeps silent.’ ” (quoting Helwig v. Fogelsong,
    
    166 Iowa 715
    , 724–25, 
    148 N.W. 990
    , 994 (1914))).         We know of no
    authority that would impose an affirmative duty of disclosure on a
    tortfeasor prior to commencement of suit in the absence of any inquiry
    by the claimant. See Ray v. Keith, 
    859 So. 2d 995
    , 996–97 (Miss. 2003)
    (rejecting as a matter of law plaintiff’s claim of equitable estoppel based
    on defendant’s failure to reveal to plaintiff that defendant was acting
    within the course of employment at time of accident, notwithstanding
    defendant’s insurer’s payment of passengers’ claims).
    We conclude the defendants have established there is no genuine
    issue of material fact with respect to Hook’s allegation of fraudulent
    concealment. Consequently, we hold as a matter of law the defendants
    are not estopped from asserting the statute of limitations as a defense to
    Hook’s claim. The plaintiff argues this result is inequitable and allows
    “unscrupulous defendants” to “thwart” the Tort Claims Act.        But this
    case is not about unscrupulous defendants thwarting the Tort Claims
    Act.   Such defendants will be estopped under the same principles we
    have applied today. This case is about an injured party and a tortfeasor
    21
    who were both unaware that a third party was liable for the injured
    party’s damages.     Under these circumstances, it is not inequitable to
    impose the consequences of this unfortunate situation on the injured
    party who bore the duty of diligent investigation.
    VI. Waiver.
    Hook argues on appeal that Lippolt waived the statute of
    limitations by failing to assert it in his initial answer to Hook’s petition in
    her first lawsuit. Although Lippolt did not allege a statute-of-limitations
    defense in his initial answer, the district court allowed him to amend his
    answer to add that defense.      Rather than appealing this ruling, Hook
    dismissed her first lawsuit. In Hook’s second lawsuit, which is the one at
    issue in this appeal, Lippolt raised the statute of limitations as an
    affirmative defense in his initial answer. Given Hook’s abandonment of
    her first lawsuit and Lippolt’s prompt pleading of his limitations defense
    in this lawsuit, we question how Lippolt’s action in the first lawsuit could
    constitute a waiver in the current lawsuit.
    Even if Lippolt’s conduct in the first lawsuit could be the basis for
    a waiver in this action, there is no evidence in the record that would
    support a finding of waiver. “ ‘[W]aiver is the intentional relinquishment
    of a known right.’ ” Huisman v. Miedema, 
    644 N.W.2d 321
    , 324 (Iowa
    2000) (quoting State v. Hallum, 
    606 N.W.2d 351
    , 354 (Iowa 2000)). At
    the time Lippolt filed his initial answer in the first lawsuit on April 9,
    2002, he had no statute-of-limitations defense. On that date, there was
    still time for Hook to file her administrative claim within the two-year
    statutory period. Consequently, Lippolt’s failure to allege the statute of
    limitations as an affirmative defense in his initial answer could not
    indicate the intentional relinquishment of that defense. Hook has failed,
    22
    therefore, to generate a genuine issue of material fact on her waiver
    argument.
    VII. Summary and Disposition.
    By virtue of section 669.24, Lippolt is not personally liable on the
    plaintiff’s negligence claim, and therefore, was not properly sued.        In
    addition, the plaintiff’s lawsuit is barred by the statute of limitations as a
    matter of law. The plaintiff had actual knowledge of her claim against
    Lippolt and imputed knowledge of her claim against the State more than
    two years before she filed her administrative claim with the state appeal
    board. In addition, there is no evidence that would generate a genuine
    issue of material fact on the plaintiff’s claims of equitable estoppel and
    waiver.
    We hold the district court erred in granting partial summary
    judgment to the plaintiff and overruling the defendants’ motions for
    summary judgment. Accordingly, we reverse the district court’s ruling
    and remand this case to the district court for entry of judgment in favor
    of the defendants on the plaintiff’s negligence claim and for dismissal of
    the State from this action.
    REVERSED AND REMANDED.
