    State of Nebraska ex rel. Douglas J. Peterson,
    Attorney General, and Scott Frakes, director
    of the Nebraska Department of Correctional
    Services, appellees, v. Senator Laura Ebke,
    chairperson of the Judiciary Committee
    of the Nebraska Legislature,
    et al., appellants.
    ___ N.W.2d ___
    Filed July 12, 2019.    No. S-18-795.
    1. Moot Question: Jurisdiction: Appeal and Error. Because mootness is
    a justiciability doctrine that operates to prevent courts from exercising
    jurisdiction, appellate courts review mootness determinations under the
    same standard of review as other jurisdictional questions.
    2. Judgments: Jurisdiction: Appeal and Error. A jurisdictional question
    that does not involve a factual dispute is determined by an appellate
    court as a matter of law, which requires the appellate court to reach a
    conclusion independent of the lower court’s decision.
    3. Jurisdiction. An actual case or controversy is necessary for the exercise
    of judicial power.
    4. Courts: Judgments. In the absence of an actual case or controversy
    requiring judicial resolution, it is not the function of the courts to render
    a judgment that is merely advisory.
    5. Moot Question. Mootness refers to events occurring after the filing
    of a suit which eradicate the requisite personal interest in the dispute’s
    resolution that existed at the beginning of the litigation.
    6. Actions: Moot Question. An action becomes moot when the issues
    initially presented in the proceedings no longer exist or the parties lack
    a legally cognizable interest in the outcome of the action.
    7. Moot Question: Words and Phrases. A moot case is one which seeks
    to determine a question that no longer rests upon existing facts or
    rights—i.e., a case in which the issues presented are no longer alive.

    8. Moot Question. The central question in a mootness analysis is whether
    changes in circumstances that prevailed at the beginning of litigation
    have forestalled any occasion for meaningful relief.
    9. Legislature: Contracts: Time. The typical understanding of state leg-
    islative bodies is that, with the limited exception of valid contractual
    obligations with third parties, pending matters die at the expiration of
    the legislative body’s 2-year term.
    10. Legislature. Any current legislative body represents the people who
    elected it and should have power equal to its predecessor.
    11. ____. The will of the past electorate should not control the future elec-
    torate and its representatives.
    12. Legislature: Time. The authority of a legislature is limited to the period
    of its own existence.
    13. Public Purpose: Statutes. An investigatory committee, being the mere
    agency of the body which appointed it, dies when the body itself dies,
    unless it is continued by law.
    14. Legislature: Time. The general rule is that the period of legislative
    existence is its 2-year term, and committee investigations and attendant
    subpoenas automatically expire upon the expiration of that term.
    15. Legislature. The Nebraska Unicameral Legislature, while unique
    because it is not a bicameral system, is not a continuing body.
    16. Constitutional Law: Legislature. The Nebraska Constitution is not a
    grant, but, rather, is a restriction on the legislative power in light of the
    otherwise plenary power of the people of each state to do as they will.
    17. Legislature: Time. Because the Nebraska Legislature is not a continu-
    ing body, a particular legislature’s biennium period of existence ceases
    at the end its biennium term.
    18. Legislature: Time: Presumptions. Like other pending matters, com-
    mittee investigations and attendant subpoenas are presumed to cease to
    exist at the end of the term in which they commenced.
    19. Legislature: Statutes: Time. There is no applicable statute or legisla-
    tive rule providing for the continuing viability of pending subpoenas
    issued by an investigatory committee of a prior biennium term.
    20. Moot Question: Appeal and Error. Under certain circumstances, an
    appellate court may entertain the issues presented by a moot case when
    the claims presented involve a matter of great public interest or when
    other rights or liabilities may be affected by the case’s determination.
    21. Moot Question: Words and Phrases. In determining whether the
    public interest exception should be invoked, the court considers the
    public or private nature of the question presented, the desirability of an
    authoritative adjudication for future guidance of public officials, and the
    likelihood of future recurrence of the same or a similar problem.

    I. NATURE OF CASE
    The underlying action in this case involves resistance to an
    investigatory subpoena issued during the 105th Legislature by
    the Judiciary Committee of the Nebraska Legislature, with the
    approval of the Executive Committee of the 105th Legislature.
    The subpoena commanded the attendance of the director of the
    Department of Correctional Services to testify at a scheduled
    committee hearing. Before the scheduled hearing, the State of
    Nebraska, represented by the Attorney General, and the direc-
    tor of the Department of Correctional Services (collectively
    the Department) sued the senators who were on the Judiciary
    Committee and the Executive Board of the Legislative Council
    at the time the subpoena was issued, as well as the Clerk of
    the Legislature who signed the subpoena (collectively the
    Senators). The Department alleged, among other things, that
    the Legislature as a whole did not vote to approve the investi-
    gation or the issuance of the subpoena; thus, the subpoena was
    not in the discharge of any duty imposed by the Legislative
    Council, by statute, or by a resolution of the Legislature, as
    described by Neb. Rev. Stat. § 50-401 (Reissue 2010). The
    Department filed an action to quash the subpoena pursuant to
    Neb. Rev. Stat. § 50-406 (Cum. Supp. 2018), and also sought,
    as to the Senators, declaratory judgment under the Uniform
    - 640 -

    Declaratory Judgments Act1 and injunctive relief in relation
    to various aspects of the procedure leading up to and includ-
    ing the subpoena. Before the Senators filed an answer to the
    complaint, the court granted the Department’s motion to quash
    the subpoena and denied the Senators’ motion to dismiss. The
    Senators appeal from the court’s order. The Department asserts
    that the appeal is moot because the subpoena was “issued by
    a committee of a Legislature which no longer exists.”2 We
    agree and hold that there is no longer a case and controversy
    as required for the exercise of our judicial power. A deter-
    mination of the underlying merits of the dispute would be
    purely advisory.
    II. BACKGROUND
    1. Internal Complaint
    Under § 84-907.10
    On March 21, 2018, Senator Ernie Chambers filed a com-
    plaint under Neb. Rev. Stat. § 84-907.10(1) (Reissue 2014)
    with Senator Dan Watermeier, chairperson of the Executive
    Board of the Legislative Council of the 105th Legislature.
    Chambers’ complaint questioned, among other things, whether
    the Nebraska Department of Correctional Services followed
    applicable state and federal laws in selecting the substances
    for execution by lethal injection and in allegedly withhold-
    ing notices and public access to various documents, in vio-
    lation of Neb. Rev. Stat. §§ 84-906.01 (Reissue 2014) and
    84-907(2) (Cum. Supp. 2018). The complaint also alleged that
    the Department of Correctional Services’ protocol violated the
    prohibition against cruel and unusual punishment found in the
    U.S. and Nebraska Constitutions, because the paralytic agent
    of the four-drug protocol served no valid purpose and would
    mask any signs of the condemned prisoner’s distress, pain, or
    suffering during the execution.

    2. Complaint Forwarded to
    Judiciary Committee
    Watermeier referred the internal complaint to Senator Laura
    Ebke, as chairperson of the Judiciary Committee of the 105th
    Legislature, pursuant to § 84-907.10(2), which requires the
    chairperson or committee staff member of the Executive Board
    to refer the complaint to “the standing committee of the
    Legislature which has subject matter jurisdiction over the issue
    involved in the rule or regulation or which has traditionally
    handled the issue.” Apparently, there was no objection, as pro-
    vided for by rule 6, § 2(a), of the Rules of the 105th Nebraska
    Unicameral Legislature, Second Session (2018), that the matter
    had been referred to the wrong committee.
    3. Public Hearing
    The Judiciary Committee of the 105th Legislature appar-
    ently chose to forgo requesting a written response from the
    agency as described in § 84-907.10(3). Instead, on April 9,
    2018, the Judiciary Committee elected, by majority vote, to
    conduct a public hearing pursuant to § 50-406 and rule 3, § 1,
    of the Rules of the 105th Nebraska Unicameral Legislature,
    and it sent a letter to the chairperson of the Executive Board
    so stating. The investigation sought to address concerns relat-
    ing to the Department of Correctional Services’ rules and
    regulations outlining the protocol for execution of the death
    penalty, codified at title 69, chapter 11, of the Nebraska
    Administrative Code. The concerns related to the process
    by which the protocol was adopted, its constitutionality, and
    whether it is consistent with the Legislature’s intent when it
    passed 2009 Neb. Laws, L.B. 36. The hearing was scheduled
    for May 8.
    Section 50-406 provides in full:
    In the discharge of any duty imposed by the Legislative
    Council, by statute, or by a resolution of the Legislature,
    the council, any committee thereof, and any standing or
    special committee created by statute or resolution of the
    Legislature may hold public hearings and may administer

    oaths, issue subpoenas when the committee has received
    prior approval by a majority vote of the Executive Board
    of the Legislative Council to issue subpoenas in connec-
    tion with the specific inquiry or investigation in question,
    compel the attendance of witnesses and the production of
    any papers, books, accounts, documents, and testimony,
    and cause the depositions of witnesses to be taken in the
    manner prescribed by law for taking depositions in civil
    actions in the district court. The council or the commit-
    tee may require any state agency, political subdivision,
    or person to provide information relevant to the commit-
    tee’s work, and the state agency, political subdivision,
    or person shall provide the information requested within
    thirty days after the request except as provided for in a
    subpoena. The statute or resolution creating a commit-
    tee may prescribe limitations on the authority granted by
    this section.
    Litigation to compel or quash compliance with author-
    ity exercised pursuant to this section shall be advanced
    on the trial docket and heard and decided by the court as
    quickly as possible. Either party may appeal to the Court
    of Appeals within ten days after a decision is rendered.
    The district court of Lancaster County has jurisdiction
    over all litigation arising under this section. In all such
    litigation the executive board shall provide for legal rep-
    resentation for the council or committee.
    Section 50-401 creates the Legislative Council, “which shall
    consist of all of the members of the Legislature” and shall
    have as its function “to consider legislative policies between
    sessions of the Legislature and carry out the duties imposed by
    section 50-402.” Neb. Rev. Stat. § 50-402(8) (Reissue 2010),
    in turn, provides that it shall be the duty of the Legislative
    Council to
    set up subcommittees within the executive board to carry
    out functions such as investigation of any area which it
    may decide is in the public interest with power to employ

    such additional personnel as may be needed to carry
    out the intent and activities of the executive board or
    the Legislature.
    Rule 3, § 1, of the Rules of the 105th Nebraska Unicameral
    Legislature, in part, described committee investigatory hearings:
    (a) Each committee of the Legislature is authorized to
    hold such hearings, to sit and act at such times and places
    during the sessions, recesses, and adjourned periods of
    the Legislature, to require by subpoena or otherwise the
    attendance of such witnesses and the production of such
    correspondence, books, papers, and documents, and to
    take such testimony, as it deems advisable. Each com-
    mittee may make investigation into any matter within its
    jurisdiction, may report such hearings as may be had by
    it, and may present to the Legislature for its consideration
    any final reports and recommendations for action result-
    ing from such investigations.
    (b) A committee’s subject-matter jurisdiction extends to
    all matters specified in the act creating the committee, or
    to all matters reasonably comprehended in the name of the
    committee. A committee’s particular jurisdiction extends
    to any bill, resolution, or other measure referred to it by
    the Legislature, until final report of the measure has been
    made by the committee to the Legislature. A committee’s
    particular jurisdiction shall also include review of the
    budgets of agencies, boards, and commissions reasonably
    encompassed in its subject-matter jurisdiction.
    (c) No committee may exercise any of the above men-
    tioned powers in a manner contrary to the Rules of the
    Legislature or in a manner which exceeds the scope of the
    act defining the purpose of the committee.
    Rule 3, § 21, of the Rules of the 105th Nebraska Unicameral
    Legislature described the subpoena powers of committees in
    relation to such hearings:
    It is within the inherent power of any legislative com-
    mittee to gather information pursuant to its regular
    - 644 -

    303 Nebraska R eports
    STATE EX REL. PETERSON v. EBKE
    Cite as 
    303 Neb. 637
    functions, and to conduct investigations of matters within
    its ­subject-matter jurisdiction.
    A committee’s power of subpoena should not be exer-
    cised unless the committee has determined that no other
    method of securing the desired information would be suc-
    cessful or practicable, and that the matter is of primary
    importance to the welfare of the State of Nebraska.
    A committee of the Legislature conducting an inves-
    tigation and gathering information, whether pursuant to
    legislative direction or pursuant to its regular functions of
    oversight and bill preparation, shall observe the following
    procedures in addition to regular committee procedures
    whenever subpoenas are issued:
    (A) Issuance of Subpoenas.
    (i) A committee may, by a majority vote of all of its
    members taken at a meeting properly called, issue a sub-
    poena requiring a person to appear before the committee
    and be examined in reference to any matter within the
    scope of the inquiry or investigation being conducted by
    the committee, but only when the committee has received
    prior approval by a majority vote of the Executive Board
    to issue subpoenas in connection with the specific inquiry
    or investigation in question.
    ....
    (iii) While the Legislature is in session, a committee
    deciding to issue subpoenas must promptly report each
    issuance to the Legislature. A record shall be made in the
    Journal reflecting the date the subpoena was issued, to
    whom it was issued, for what purpose it was issued, and
    the date on which testimony or production of documents
    is to take place. Under extraordinary circumstances, the
    identity of the person subpoenaed may be withheld from
    publication if necessary to protect the safety of an indi-
    vidual or the confidentiality of the matters to be heard.
    (iv) A person subpoenaed to attend a hearing of a com-
    mittee shall receive the same fees and allowances as a
    - 645 -

    STATE EX REL. PETERSON v. EBKE
    Cite as 
    303 Neb. 637
    person subpoenaed to give testimony in an action pending
    in a court of record.
    (B) Notice to Witnesses.
    ....
    (ii) Any person who is served with a subpoena to
    attend a hearing of a committee shall also be served with
    a copy of the act defining the purpose of the committee,
    a copy of the rules under which the committee functions,
    a general statement informing him or her of the subject
    matter of the committee’s investigation or inquiry, and a
    notice that he or she may be accompanied at the hearing
    by counsel of his or her own choosing.
    ....
    (G) Contempt.
    ....
    The chairperson of a committee may apply to the
    Legislature or, during the interim, to the district court
    of any county to compel obedience by proceedings for
    contempt.
    (H) Penalties.
    (i) A person guilty of contempt under the provision
    of these rules shall be subject to punishment pursuant to
    RRS 50-105 and 50-106 during the session, or to RRS
    50-407 when the Legislature is not in session.
    (ii) If a committee fails in any material respect to
    comply with the requirements of these rules, any per-
    son subject to a subpoena or a subpoena duces tecum
    who is injured by such failure shall be relieved of any
    requirement to attend the hearing for which the subpoena
    was issued or, if present, to testify or produce evidence
    therein; and such failure shall be a complete defense
    in any proceeding against such person for contempt or
    other punishment.
    4. Decision to Issue Subpoena
    On April 10, 2018, the Judiciary Committee formally invited
    Scott Frakes, director of the Department of Correctional
    - 646 -

    303 Nebraska R eports
    STATE EX REL. PETERSON v. EBKE
    Cite as 
    303 Neb. 637
    Services, to testify at the hearing. Frakes did not respond to
    the invitation. On April 18, Ebke asked the Executive Board
    to provide approval to the Judiciary Committee to issue a sub-
    poena and possible subpoenas duces tecum to Frakes. While
    there was some discussion at the meeting of the Executive
    Board as to whether to give Frakes more time to respond to the
    invitation so that he could attend the hearing voluntarily, April
    18 was the day of adjournment for the legislative session. A
    majority (by one vote) of the Executive Board voted to approve
    the Judiciary Committee’s issuance of a subpoena.
    (a) Subpoena
    A subpoena was issued to Frakes on April 24, 2018. The
    subpoena states: “Pursuant to statutory section 50-406 R.R.S.,
    the Judiciary Committee of the Nebraska Legislature hereby
    compels your presence to testify at 9:00 a.m. on Tuesday,
    May 8, 2018, in Room 1113 of the Nebraska State Capitol
    Building, 1445 K Street, Lincoln, NE 68508.” The subpoena
    was signed by Ebke, as the chairperson of the Judiciary
    Committee of the Nebraska Legislature, and by the Clerk of
    the Nebraska Legislature.
    (b) Informational Letter
    On April 25, 2018, the Judiciary Committee sent Frakes
    an informational letter pursuant to rule 3, § 21(B)(ii), of the
    Rules of the 105th Nebraska Unicameral Legislature. The
    letter explained that a majority of the Judiciary Committee
    had voted to conduct a hearing related to concerns over
    the Department of Correctional Services’ execution protocol
    and, after obtaining the approval of the Executive Board, a
    majority of the Legislative Council had voted to subpoena
    Frakes’ testimony. The Judiciary Committee explained that
    after Frakes had ignored a series of attempts to contact him
    and make arrangements for his voluntary testimony, the com-
    mittee had determined that there was no method other than a
    subpoena of securing his attendance at the hearing. The letter
    informed Frakes that he could be accompanied at the hearing

    303 Neb. 637
    by counsel of his own choosing. It did not specify whether
    Frakes would receive any compensation in the form of fees
    and allowances for his time.
    5. Complaint
    On May 1, 2018, before the scheduled date of the hearing,
    the Department sued the Senators. The complaint generally set
    forth the facts already described and asserted that the district
    court had jurisdiction over the action under Neb. Rev. Stat.
    § 24-302 (Reissue 2016) and §§ 25-21,149 and 50-406.
    In what was designated as its first cause of action, the
    Department focused on its conclusion that § 84-907.10 did
    not authorize the Judiciary Committee to hold hearings or
    issue subpoenas in relation to internal complaints thereun-
    der. The Department requested a declaration that in issuing
    the subpoena, the Senators had violated § 50-406 and rule 3,
    § 1 or § 21, of the Rules of the 105th Nebraska Unicameral
    Legislature. The Department also asked the court to enjoin the
    Senators from future acts violating these provisions.
    In its designated second cause of action, the Department
    focused on its allegation that the subpoena was not issued in
    the discharge of a duty imposed by the Legislative Council,
    by statute, or by a resolution of the Legislature, as required by
    § 50-406. According to the Department, all of these duties can
    be imposed only by a majority vote of the Legislative Council,
    which is the entire Legislature. Because no vote by the entire
    Legislature was held in relation to the hearing and subpoena at
    issue, the Department asserted that the hearing and subpoena
    were not in the discharge of any of the three duties specified
    by § 50-406. The Department again requested that the court
    declare that the Senators violated § 50-406 and enjoin the
    Senators from similar future acts violating § 50-406.
    In its designated third cause of action, the Department
    focused on allegations that Watermeier had referred Chambers’
    internal complaint to the wrong committee, asserting that
    the Government, Military and Veterans Affairs Committee
    was the standing committee with “subject-matter jurisdiction”
    - 648 -

    303 Nebraska R eports
    STATE EX REL. PETERSON v. EBKE
    Cite as 
    303 Neb. 637
    over the issues involved in the internal complaint. Further, in
    its third cause of action, the Department highlighted its alle-
    gations that the Senators failed to follow rule 3, § 21(B)(ii),
    of the Rules of the 105th Nebraska Unicameral Legislature
    by failing to serve Frakes with a copy of the act defining the
    purpose of the Judiciary Committee and by not offering to
    pay him fees and allowances commensurate with those given
    to persons subpoenaed to give testimony in an action pending
    in a court. Finally, in its designated third cause of action, the
    Department asserted that the vote of the Judiciary Committee
    had not been “properly called.” The Department asserted
    that in the process of issuing the subpoena, the Senators
    had thereby violated rule 3, § 21(A)(i) and (iv) and (B)(ii),
    of the Rules of the 105th Nebraska Unicameral Legislature.
    The Department asked for a declaration that the Senators
    “failed in all material respects to comply with the require-
    ments of the Rules of the Nebraska Unicameral Legislature
    and accordingly, . . . Frakes is relieved of any requirement to
    attend the hearing for which the subpoena was issued pursu-
    ant to Rule 3, Section 21(H)(ii) of the Rules of the Nebraska
    Unicameral Legislature.”
    In its designated fourth cause of action, the Department
    asserted that the Senators’ actions were not within the sphere
    of legitimate legislative activity and that by virtue of the
    subpoena, the Senators sought to exercise a power properly
    belonging to the judicial branch by determining a case and
    controversy regarding the Department’s compliance with the
    Administrative Procedure Act, the constitutionality of the exe-
    cution protocol, and any other conflicts between the execu-
    tion protocol and state and federal laws and regulations. The
    Department requested a declaration that the Senators thereby
    violated the separation of powers provision in the Nebraska
    Constitution, Neb. Const. art. II, § 1, and asked that the court
    enjoin the Senators from future acts violating article II, § 1.
    In its fifth and final designated cause of action, the
    Department requested that pursuant to § 50-406, the court

    quash the subpoena, due to the alleged violations of Neb.
    Const. art. II, § 1; § 50-406; and rule 3, §§ 1 and 21, of the
    Rules of the 105th Nebraska Unicameral Legislature.
    In its prayer for relief, in addition to the relief requested
    within its five causes of action, the Department asked for costs.
    6. Motion to Quash
    The day after filing its complaint, the Department filed a
    motion to quash subpoena. The motion stated that the grounds
    for the motion had been set forth in the complaint and included,
    but were not limited to, the Senators’ alleged violations when
    issuing the subpoena of §§ 50-406 and 84-907.10 and rule 3,
    §§ 1 and 21, of the Rules of the 105th Nebraska Unicameral
    Legislature. The motion also described that pursuant to
    § 50-406, the matter “‘shall be advanced on the court docket
    and heard and decided by the court as quickly as possible.’”
    7. Order Staying Subpoena
    and H earing
    Pursuant to a stipulation, on May 4, 2018, the court stayed
    the subpoena and the “subpoena’s hearing date” until “such
    time as the Court finally resolves the issues raised in the
    Complaint.”
    8. Motion to Dismiss
    On May 10, 2018, the Senators moved to dismiss the com-
    plaint pursuant to Neb. Ct. R. Pldg. § 6-1112(b)(1), (4), (5),
    and (6), on the alternative grounds that (1) the named defend­
    ants were absolutely immune from litigation pursuant to the
    Neb. Const. art. III, § 26, the speech and debate clause; (2)
    the judiciary lacks the authority under separation of powers
    principles to declare the Judiciary Committee’s actions uncon-
    stitutional, issue a permanent injunction against the Judiciary
    Committee or its members, quash the subpoena, or enter a
    money judgment against the Judiciary Committee or its mem-
    bers; (3) § 50-406 is overbroad and violates the speech and
    debate and separation of powers clauses to the extent it gives

    courts the power to oversee legislative committees’ authority
    to hold public hearings, make specific inquiry or investiga-
    tion, compel the production of documents or testimony, and
    require a state agency to provide information relevant to the
    committee’s work; (4) the Attorney General lacks standing to
    sue members of the Legislature, given the Attorney General’s
    duty to defend the Legislature imposed by Neb. Rev. Stat.
    § 84-209 (Reissue 2014); and (5) service was improper because
    the Attorney General attempted to serve process on each of the
    individual defendants by sending the summonses by certified
    mail to the Attorney General’s own offices.
    9. Hearing on Motion to Dismiss
    and Motion to Quash
    A hearing was held on the Senators’ motion to dismiss and
    the Department’s motion to quash. At the hearing, the Senators
    focused on legislative immunity, arguing that the analysis
    “starts and ends with” the fact that committee issuance of
    investigatory subpoenas is within the legitimate legislative
    sphere and thus the district court lacked jurisdiction to “pass
    judgment on the committee’s processes and motives for issu-
    ing the subpoena.” The Senators asserted that § 50-406 could
    not waive, through legislative enactment, a constitutionally
    protected immunity.
    The Department responded that while it agreed the members
    of the Legislature would be immune from litigation stemming
    from a lawfully issued subpoena, this subpoena was not law-
    fully issued. The Department also asserted that the Senators
    could not rely on § 50-406 in issuing the subpoena while at
    the same time challenging as unconstitutional the language of
    § 50-406 purporting to grant the district court for Lancaster
    County jurisdiction over litigation to compel or quash compli-
    ance with authority exercised pursuant to § 50-406.
    On the underlying merits of the motion to quash, the
    Senators argued that the investigatory subpoena was within
    its authority to review and consider whether adjustments are

    necessary to its laws pertaining to the death penalty and del-
    egating to the executive branch the development of the death
    penalty protocol. The Department argued that the subpoena at
    issue was not legislative and that the Senators failed to comply
    with the procedure set forth in § 84-907.10.
    10. Order Denying Dismissal and
    Sustaining Motion to Quash
    The court ruled on both the Senators’ motion to dismiss and
    the Department’s motion to quash in an order dated August
    8, 2018.
    The court overruled the Senators’ motion to dismiss. The
    court’s reasoning for this ruling was that the motion raised
    “several issues, including novel questions under Nebraska’s
    Constitution[,] that our appellate courts have not yet addressed.”
    Thus, the court “decline[d] to sustain the Motion [to dismiss].”
    The court granted the Department’s motion to quash. The
    court reasoned that while the subpoena may have satisfied
    the requirement that it receive prior approval by a majority
    vote of the Executive Board of the Legislative Council, the
    subpoena was not “‘[i]n the discharge of any duty imposed
    by the Legislative Council, by statute, or by a resolution of
    the Legislature . . . .’” The court noted that the Legislative
    Council and the Executive Board are distinct decisionmaking
    bodies and that § 50-402 refers to the Legislative Council as
    having the duty of collecting information, while Neb. Rev.
    Stat. § 50-401.01 (Cum. Supp. 2018), describes the Executive
    Board’s duties as administrative, such as hiring staff and con-
    tracting for professional services. The court did not specifi-
    cally address rule 3, § 21, of the Rules of the 105th Nebraska
    Unicameral Legislature.
    11. Notice of A ppeal and
    A ppellate Motions
    On August 20, 2018, the Senators filed their notice of
    appeal. On January 9, 2019, the 106th Nebraska Legislature

    commenced. Because the 105th Legislature sat in an even year,
    the end of the 105th Legislature was the end of a biennium.
    The new biennium commenced with the 106th Legislature in
    2019. Several of the named senators are no longer in office.
    The Department filed a “Suggestion of Mootness” based on
    this change of circumstances.
    III. ASSIGNMENTS OF ERROR
    The Senators assign that the lower court erred in (1) not
    finding that the Senators are absolutely immune from liti-
    gation under Nebraska’s speech and debate clause; (2) not
    finding that § 50-406, on its face, violates the Nebraska
    Constitution’s speech and debate and separation of powers
    clauses; (3) not finding that § 50-406, as applied to legisla-
    tive subpoenas, violates the Nebraska Constitution’s speech
    and debate and separation of powers clauses; (4) not finding
    that the Attorney General lacked standing or capacity to sue
    the Senators; (5) not dismissing the complaint; (6) finding that
    the Judiciary Committee was not discharging a duty imposed
    by the Legislative Council, by statute, or by resolution in the
    Legislature; (7) not finding that the Judiciary Committee had
    jurisdiction to investigate, hold hearings, and issue subpoenas
    independent of § 50-406; and (8) granting the Department’s
    motion to quash.
    IV. STANDARD OF REVIEW
    [1,2] Because mootness is a justiciability doctrine that oper-
    ates to prevent courts from exercising jurisdiction, we have
    reviewed mootness determinations under the same standard of
    review as other jurisdictional questions.3 A jurisdictional ques-
    tion that does not involve a factual dispute is determined
    by an appellate court as a matter of law, which requires the
    appellate court to reach a conclusion independent of the lower
    court’s decision.4

    V. ANALYSIS
    [3,4] Mootness is a justiciability doctrine that operates to
    prevent courts from exercising jurisdiction.5 An actual case or
    controversy is necessary for the exercise of judicial power.6 In
    the absence of an actual case or controversy requiring judicial
    resolution, it is not the function of the courts to render a judg-
    ment that is merely advisory.7 Therefore, as a general rule, a
    moot case is subject to summary dismissal.8 It is well estab-
    lished that when a party or parties are aware that appellate
    issues have become moot during the pendency of the appeal
    and such mootness is not reflected in the record, in the interest
    of judicial economy, a party may file a suggestion of mootness
    in the Nebraska Supreme Court or Nebraska Court of Appeals
    as to the issue or issues claimed to be moot.9
    [5-8] Mootness refers to events occurring after the filing
    of a suit which eradicate the requisite personal interest in
    the dispute’s resolution that existed at the beginning of the
    litigation.10 An action becomes moot when the issues initially
    presented in the proceedings no longer exist or the parties lack
    a legally cognizable interest in the outcome of the action.11 A
    moot case is one which seeks to determine a question that no
    longer rests upon existing facts or rights—i.e., a case in which
    the issues presented are no longer alive.12 The central question
    in a mootness analysis is whether changes in circumstances

    that prevailed at the beginning of litigation have forestalled any
    occasion for meaningful relief.13
    The change in circumstances that the Department argues
    renders this appeal moot is the commencement of the 106th
    Legislature. We agree. The underlying complaint challenged
    the subpoena that was issued by the 105th Legislature to attend
    a hearing to be conducted by the Judiciary Committee of the
    105th Legislature. The 105th Legislature, sitting in 2018, was
    the last legislative year of a biennium term. The order that is the
    subject of this appeal, which quashed the subpoena as unlaw-
    fully issued and which refused to dismiss the Department’s
    action on the ground of legislative immunity, was issued dur-
    ing that prior biennium term and before the commencement of
    the present biennium term. The hearing Frakes resisted attend-
    ing was never held and, as we will explain, the investigation,
    hearing, and subpoena at issue automatically expired upon the
    completion of the legislative biennium in which the investiga-
    tion took place. This eradicated the requisite personal inter-
    est in the dispute’s resolution that existed at the beginning of
    the litigation.
    [9-12] The typical understanding of state legislative bodies
    is that, with the limited exception of valid contractual obliga-
    tions with third parties,14 pending matters die at the expiration
    of the legislative body’s 2-year term.15 This understanding
    derives from policies dating back to British parliamentary
    function, which disfavored entrenchment and sought to avoid
    the “dead hand problem.”16 Any current legislative body repre-
    sents the people who elected it and should have power equal to

    its predecessor.17 The will of the past electorate should not con-
    trol the future electorate and its representatives.18 Recognizing
    these principles, we held in State ex rel. Stenberg v. Moore 19
    that a past legislature impermissibly bound future legislatures
    by passing a law declaring null and void certain future legis-
    lation in the event it failed to include specified estimates and
    appropriations. “‘The authority of a legislature,’” we observed,
    “‘is limited to the period of its own existence.’”20 We held that
    the law in question violated Neb. Const. art. III, §§ 1, 13, and
    14, because it attempted to restrict the constitutional power of
    a succeeding legislature to legislate.21
    [13] An investigatory committee, “being the mere agency
    of the body which appointed it, dies when the body itself
    dies, unless it is continued by law.”22 In such circumstances,
    an outstanding subpoena to attend an investigatory hearing
    by the committee also dies. It is a pending matter that dies
    at the expiration of the legislative body’s 2-year term. Thus,
    in Eastland v. United States Servicemen’s Fund,23 the U.S.
    Supreme Court indicated that an action to enjoin enforcement
    of the investigatory subpoena issued by the U.S. House of
    Representatives had automatically expired during the pen-
    dency of the litigation, due to the cessation of the legislative
    term in which an investigatory subpoena had been issued.
    In subsequent cases, the U.S. District Court for the District
    of Columbia has explicitly held that subpoenas issued by
    an investigatory committee of the House of Representatives

    during one term expire upon a new term, because the prior
    House of Representatives has at that point ceased to exist as a
    legal entity.24 This, in turn, renders moot any litigation seeking
    to avoid or enforce compliance with the subpoena.25 This is
    analogous to federal decisions holding that with the expira-
    tion of a grand jury, so too expires the ability of the court
    to enforce a grand jury subpoena, rendering moot challenges
    relating to the subpoena.26
    The only state cases addressing the continued life of an
    investigatory committee focus on the power of a committee
    to act after adjournment sine die, as opposed to the end of a
    term, but those courts hold that committees have the authority
    to do so only when it is specifically conferred.27 State courts
    have not had occasion to address whether investigatory sub-
    poenas automatically expire between legislative terms. At least
    one state decision has, however, held that subpoenas issued
    by standing committees of municipal councils automatically
    expire by reason of new elections.28
    [14] The general rule is that the period of legislative exis-
    tence is its 2-year term, and committee investigations and
    attendant subpoenas automatically expire upon the expira-
    tion of that term. It is true that the U.S. Senate, as opposed
    to the House of Representatives, has been characterized as
    a “‘continuing body.’”29 This is by virtue of the fact that its

    members are elected for 6 years and so divided into classes
    that the seats of only one-third become vacant at the end of
    each Congress, with two-thirds (or a quorum) always con-
    tinuing into the next Congress, save as vacancies may occur
    through death or resignation.30 Further, the Senate, unlike the
    House of Representatives, does not adopt new procedural rules
    or readopt the old procedural rules upon each new term; the
    old rules of the Senate remain in effect and are revised only
    on rare occasion.31 But even with such continuing existence, it
    is not entirely clear that Senate investigatory subpoenas auto-
    matically continue to be enforceable after the Senate’s term
    has ended, without reissuance or other affirmative acts by the
    senators holding office in the new term.32 It has been held that
    even the Senate cannot exercise its inherent contempt powers
    to enforce an investigatory subpoena after adjournment sine
    die—let alone after expiration of its term.33
    [15,16] In any event, no state legislative body has been
    similarly described as a “continuing body.” We hold that the
    Nebraska Unicameral Legislature, while unique because it is
    not a bicameral system, is likewise not a “continuing body.”
    The Nebraska Constitution is not a grant, but, rather, is a
    restriction on the legislative power 34 in light of the otherwise
    “plenary power of the people of each state to do as they will.”35
    The constitutional provisions restricting the power of the leg-
    islature describe 2-year biennium terms that begin with odd-
    numbered years and end with the following even-numbered

    year. Neb. Const. art. III, § 10, describes the length of legis-
    lative sessions in odd versus even-numbered years and states
    that only in an odd-numbered year may “[b]ills and resolu-
    tions under consideration by the Legislature upon adjournment
    . . . be considered at the next regular session, as if there had
    been no such adjournment.” There is no analogous constitu-
    tional provision for the U.S. Senate. Furthermore, approxi-
    mately one-half of the members of the Nebraska Unicameral
    Legislature are subject to staggered elections for their 4-year
    terms,36 not the mere one-third of the U.S. Senate. And the
    existence of staggered elective terms, which seems to be the
    only basis for equating our Legislature to the U.S. Senate, is a
    relatively new phenomenon. In the bicameral era, members of
    the Legislature, including both the House of Representatives
    and the Senate, were elected for terms consisting of only 2
    years.37 At the inception of the unicameral era, the members
    of the new one-house Legislature were elected only for 2-year
    terms.38 This continued, despite an intervening constitutional
    amendment,39 until the voters adopted an amendment for stag-
    gered 4-year terms in 1962.40 The parties have not pointed to,
    nor has our research disclosed, any legislative text or history
    from 1962 stating any intent to make the Nebraska Legislature
    a “continuing body.” 41 Finally, unlike in the Senate, all pro-
    cedural rules of the Nebraska Unicameral Legislature are
    adopted by a majority vote at the “commencement of each
    regular session in odd-numbered years,” and the adopted rules
    “govern the Legislature for a period of two years.” 42 This

    demonstrates the Legislature’s collective understanding that
    it is not a “continuing body,” but, rather, is a new Legislature
    established at the regular legislative session commencing in
    each odd-numbered year. Obviously, that session would next
    follow the general election in each even-numbered year, at
    which a new term begins for approximately one-half of its
    members. The Legislature itself numbers its sessions consist­
    ent with that understanding.
    [17,18] Because the Nebraska Legislature is not a “continu-
    ing body,” a particular legislature’s biennium period of exis-
    tence ceases at the end its biennium term. Like other pending
    matters, committee investigations and attendant subpoenas are
    presumed to cease to exist at the end of the term in which they
    commenced. The committee investigation dies when the body
    dies, unless it is continued by a valid law.
    [19] And there is no applicable statute or legislative rule
    providing for the continuing viability of pending subpoenas
    issued by an investigatory committee of a prior biennium
    term. We need not decide whether such a statute or rule, if it
    existed, would be an impermissible restriction on future leg-
    islatures, like the statute addressed in State ex rel. Stenberg v.
    Moore.43 The applicable statutes and procedural rules of the
    105th Legislature contemplated the expiration of investiga-
    tory committees at the end of each biennium term and, by
    necessary implication, the expiration of the expired commit-
    tees’ pending hearings and attendant subpoenas. Neb. Rev.
    Stat. § 50-410 (Reissue 2010), describes that the Legislative
    Council “shall meet at least once in each biennium.” Rule
    3, § 2(c), provided that the membership of all standing and
    select committees shall continue only during the duration of
    the biennium. Under this rule, new membership of commit-
    tees was to be appointed at the beginning of each session
    beginning in odd-numbered years and continue only until the
    regular session in the next subsequent odd-numbered year.

    Similarly, at the commencement of each regular session in
    odd-­ numbered years, new members of the executive board
    were to be elected.44
    While rule 3, § 1(b), described the power of committees to
    sit and act during session, recesses, and adjourned periods, and
    it stated that committees had “jurisdiction” “until final report,”
    it did not purport to address a new biennium legislative term
    and the survivability of subpoenas beyond the commencement
    of the odd-numbered year during which the committee will
    be reconstituted with new members. Further, rule 3, § 1(c),
    explained that “[n]o committee may exercise any of the above
    mentioned powers in a manner contrary to the Rules of the
    Legislature or in a manner which exceeds the scope of the act
    defining the purpose of the committee.”
    Thus, the Judiciary Committee’s investigation at issue in
    this appeal automatically expired with the expiration of the
    Legislature in which it had begun, and the subpoena that
    was the subject of the district court’s order presently appealed
    from died with it. While it might be argued under different
    circumstances that a failure to appear, as subpoenaed, at a
    past legislature’s investigatory hearing is a historical fact
    subjecting the witness to contempt even after a new legis-
    lature commences, that did not occur here. The scheduled
    hearing was never held. Because the subpoena has expired
    and the hearing was never held, no real controversy pres-
    ently exists regarding the subpoena’s enforceability against
    Frakes.
    As the enforceability against Frakes was the only issue
    determined in the court’s order quashing the subpoena pursu-
    ant to § 50-406, the court’s order in that regard is moot. It
    follows that no real controversy presently exists concerning
    the Senators’ immunity defenses to Frakes’ challenges under
    § 50-406 to the subpoena’s enforceability, and the district
    court’s order denying the Senators’ motion to dismiss Frakes’
    44
    Rule 1, § 1.

    challenges under § 50-406 are likewise moot.45 We do not
    consider to be presently before us in this interlocutory appeal
    the court’s ruling on the Senators’ motion to dismiss as it per-
    tained to other claims brought by the Department outside of
    § 50-406 and, thus, outside of a special proceeding.46 Those
    claims appear to still be pending below, and the Department
    is free to voluntarily dismiss those claims or either party
    may request a ruling by the district court that the claims
    are moot.
    [20,21] Under certain circumstances, an appellate court
    may entertain the issues presented by a moot case when the
    claims presented involve a matter of great public interest or
    when other rights or liabilities may be affected by the case’s
    determination.47 In determining whether the public interest
    exception should be invoked, the court considers the public
    or private nature of the question presented, the desirability
    of an authoritative adjudication for future guidance of public
    officials, and the likelihood of future recurrence of the same
    or a similar problem.48 While this case involves questions of
    a public nature, it is not at all clear that the same or a similar
    problem is likely to recur and, relatedly, that there is a need
    to provide future guidance for public officials. Indeed, in the
    event that the Judiciary Committee of the current or future
    bienniums were to similarly issue a similar subpoena, the
    statutes and rules governing the issuance, enforcement, and
    resistance to investigatory subpoenas may have changed. We
    will not issue an opinion on a hypothetical set of facts that are
    unlikely to recur.

    VI. CONCLUSION
    Because the Nebraska Legislature, like most state legisla-
    tive entities, is not a continuing body, the subpoenas at issue
    expired at the commencement of the 106th Legislature. Even
    if we were to agree with the Senators’ legal position, we could
    not grant the relief they seek. This prevents this court from
    reaching the substantive issues raised by the parties.
    We therefore dismiss the appeal as moot. We also dismiss
    as moot the Department’s appellate motion to substitute the
    named senators who are no longer in office with their suc-
    cessors in the 106th Nebraska Legislature, which motion the
    Department explained “should not be construed as conceding
    any issue pertaining to the continued justiciability of this case
    on mootness or any other basis.” The Department is free to
    make such motion below if it wishes to still pursue any claims
    set forth in the complaint outside of § 50-406.
    A ppeal and motion to substitute
    parties dismissed.
    Miller‑Lerman, J., concurring.
    I concur in the per curiam decision, but write separately to
    address the timing of a future similar case, if any.
    Among the features of Nebraska’s unique Unicameral sys-
    tem is the fact that the Legislature reconstitutes itself every 2
    years. The Nebraska Legislature is not a continuing body. As a
    result, the subpoena issued by the 105th Legislature ceased to
    be a demand of the Legislature and issues related to its issu-
    ance became moot.
    This circumstance leaves unanswered the underlying sub-
    stantive issues identified in the per curiam opinion including:
    whether the Nebraska Department of Correctional Services’
    rules and regulations outlining the protocol for execution of
    the death penalty, and the process by which the protocol was
    adopted, were constitutional and consistent with Nebraska stat-
    utes; whether delegation of development of the death penalty
    protocol to the executive branch would benefit from more

    strict legislative boundaries; whether the department followed
    applicable state and federal law in selecting the substances for
    lethal injection; and whether notices and public access to vari-
    ous documents were consistent with Nebraska statutes.
    The foregoing issues could be addressed by a similar sub-
    poena issued by the 106th Legislature timed in a manner which
    would forestall mootness. Were the current or future Legislatures
    to act earlier in the biennium, a court challenge, if any, could
    mature and the Judiciary at all levels would be obligated to
    advance consideration of the case.
