OPINION
MARTONE, Justice.
¶ 1 These are consolidated petitions for special action brought by the Citizens Clean Elections Commission and the Arizonans for Clean Elections against VotePac and others seeking expedited review of an order of the Superior Court of Arizona in Maricopa County holding that the Citizens Clean Elections Act, A.R.S. §§ 16-940 to -961, violates the Arizona Constitution and is thus invalid. Given the imminence of the year 2000 general election and its statewide importance, we agreed with the parties that this case presented an appropriate occasion in which to exercise special action jurisdiction directly in this court. See Rule 7(b), R.P. Spec. Actions.
I.
Background
¶ 2 The Citizens Clean Elections Act was adopted by the people as an initiative. It establishes a complex system of public campaign financing for participating candidates who agree to limit their fund raising and spending in statewide elections. It also reduces contribution limits for candidates who choose not to participate. See A.R.S. § 16-941. The Citizens Clean Elections Commission is responsible for administering the program. See A.R.S. § 16-955. Arizonans for Clean Elections is the committee that promoted the initiative measure. VotePac is a political committee which, along with the individual real parties in interest, brought an action in the Superior Court of Arizona in Maricopa County against the Governor and Secretary of State seeking a declaration of the Act’s invalidity under the Arizona Constitution. There are thus no federal issues before us. The defendants chose not to participate and instead deferred to the interve-nors, Citizens Clean Elections Commission and Arizonans for Clean Elections. Agreeing that there were no factual disputes, the parties filed cross-motions for summary judgment.
¶ 3 The state constitutional attacks revolve around the ways in which persons become members of, and are removed from, the Citizens Clean Elections Commission. Under the Act, members are appointed by statewide public officials, beginning with the Governor, by alternating political party affiliation. A.R.S. § 16-955(B) to (D). “[Mjembers of the supreme court in order of seniority” are among the officials who may appoint. A.R.S. § 16-955(C). It has happened that the next highest ranking statewide officeholders were members of this court, each of whom promptly disqualified himself and herself.
¶4 The officeholders must appoint from lists of three candidates nominated by the Commission on Appellate Court Appointments, A.R.S. § 16-955(B) to (C), a commission the constitution vests with the responsibility to screen and nominate candidates for appellate judgeships. See Ariz. Const, art. VI, §§ 36 and 37. The Chief Justice of this court is the chair of the Commission on [519]*519Appellate Court Appointments. Id. at § 36. Members of the Clean Elections Commission may be removed by the Governor for statutory causes, but only with the concurrence of the senate. A.R.S. § 16-955(E).
¶ 5 The trial court held that the involvement of members of this court on the Commission on Appellate Court Appointments and in the appointment of members to the Clean Elections Commission did not violate the separation of powers doctrine; that subjecting the Governor’s removal authority to senate approval did violate the doctrine of separation of powers, but that such provision was severable; that the title “Citizens Clean Elections Act” is constitutionally valid; but that the expansion of the duties of the Commission on Appellate Court Appointments beyond the scope of judicial appointments was repugnant to the Arizona Constitution and such provision was not severable.
¶ 6 In their consolidated petitions for special action, the Citizens Clean Elections Commission and Arizonans for Clean Elections contend that the trial court erred in concluding that the use of the Commission on Appellate Court Appointments to nominate candidates for appointment to the Citizens Clean Elections Commission violated the Arizona Constitution. If it does, though, they claim that part of the Act is severable and thus the remainder of the Act should survive. They also contend that the trial court erred in concluding that the senate’s role in the removal of commission members violated separation of powers.
¶ 7 On cross-petition, VotePac contends that the trial court erred in concluding that the involvement of members of this court on the Commission on Appellate Court Appointments and in the appointment process did not violate separation of powers. It also contends that the trial court erred in concluding that the title of the Act was substantively valid under the constitution.
II.
Commission on Appellate Court Appointments
¶ 8 Article VI, sections 36 and 37 of the Arizona Constitution vest the Commission on Appellate Court Appointments with but one function: the authority to screen and nominate candidates to the Governor for appointment to the appellate courts of Arizona. These provisions contain no express grant of power to the legislature to enlarge the function or scope of the Commission. See Ariz. Const, art. VI, §§ 36 and 37. In contrast, other article VI grants of power do contain some express grants of authority to the legislature. For example, article VI, section 5 specifically describes the jurisdiction of this court, along with “[sjuch other jurisdiction as may be provided by law.” Ariz. Const, art. VI, § 5(6). Article VI, section 9 allows the legislature to create an intermediate appellate court and give it such “jurisdiction, powers, duties and composition ... [as] shall be provided by law.” Article VI, section 14 defines the jurisdiction of the superior court, along with “such other jurisdiction as may be provided by law.” Ariz. Const, art. VI, § 14(11). Article VI, section 32 provides for the jurisdiction of the justice courts and other “courts inferior to the superior court,” along with such jurisdiction “as provided by law.”
¶ 9 When we venture outside the scope of article VI, we find the same pattern. For example, under article XV, section 6, the legislature is granted the authority to enlarge the powers of the Arizona Corporation Commission. Under article V, section 9, the duties of the Secretary of State, Treasurer, Attorney General, and Superintendent of Public Instruction “shall be as prescribed by law.” Under article XIX, the legislature “fix[es]” the duties of the State Mine Inspector.
¶ 10 VotePac argues that if we were to just look at the language of the constitution and compare article VI, sections 36 and 37 with all other provisions of the constitution, one would conclude that the different treatment must have some significance. One conclusion that might be drawn from textual analysis alone is that where the constitution intends that the legislature have the power to expand the duties of a constitu[520]*520tional entity, the constitution will so state.1 The corollary would be that if the constitution does not so state, then the functions and the duties of the constitutional entity are only those specifically described by the constitutional grant of authority.
¶ 11 The Citizens Clean Elections Commission and the Arizonans for Clean Elections argue that we have held otherwise. They turn to Cox v. Superior Court, 73 Ariz. 93, 237 P.2d 820 (1951), and Earhart v. Frohmil-ler, 65 Ariz. 221, 178 P.2d 436 (1947) for the proposition that unless the constitution expressly denies the legislature a particular power, it has it. From that, they argue that since article VI, sections 36 and 37 do not expressly prohibit the legislature from adding to the functions of the Commission on Appellate Court Appointments, the legislature may do so.
¶ 12 We believe Citizens Clean Elections Commission’s and Arizonans for Clean Elections’ reading of Cox and Frohmiller omits any consideration of the doctrine of implied limitations, expressly acknowledged in Cox and Frohmiller. In Cox, the issue was whether the legislature could vest the superi- or court with appellate jurisdiction over cases that originate before an administrative agency. Article VI, section 6, as it then existed, [now article VI, section 14] provided that the superior court had appellate jurisdiction over cases arising in justice and other inferior courts “as may be prescribed by law.” Cox, 73 Ariz. at 95, 237 P.2d at 821. It was argued that because an administrative agency was not a justice or other inferior court, the legislature had no power to enlarge the jurisdiction of the superior court. We rejected this contention and held that “unless the constitution has prohibited the legislature from enlarging the appellate jurisdiction of the superior court, it has, in exercising the sovereign power of the state, the power to enlarge but not diminish such appellate jurisdiction.” Id. at 97, 237 P.2d at 822. We relied on Frohmiller for the proposition that we do not look to the constitution to determine whether the legislature is authorized to do an act but only to see if it is prohibited. Id. at 96, 237 P.2d at 821. But we also relied on Frohmiller for the proposition that “except for those things necessarily inhibited by the Federal or state constitution, the state legislature may pass any act.” Id. (emphasis added).
¶ 13 In Frohmiller, the question was whether the legislature could constitutionally authorize the payment of subsistence and lodging expenses to those members of the legislature and their employees who were away from home while attending legislative business. 65 Ariz. at 223, 178 P.2d at 437. It was argued that because the constitution did not expressly authorize the legislature to enact a per diem statute, it could not do so. We rejected this argument and said that the legislature does not need express authorization to enact legislation. Id. at 224, 178 P.2d at 438. But we also acknowledged that the legislature is subject to any limitations imposed by the federal and state constitutions. Id. It was argued that the provision for subsistence and lodging was an improper increase in compensation under article IV, section 1(2) of the constitution. We upheld the statute stating that repayment for personal expenses “does not constitute additional compensation but is merely a reimbursement.” Id. at 226,178 P.2d at 438.
¶ 14 We certainly agree with and reaffirm the rule of Frohmiller and Cox that the legislature need not look to an express grant of authority in order to justify an enactment. But we also agree with Frohmiller and Cox that any exercise of legislative power is subject to the limitations imposed by the constitution. And just as no express grant of authority is required, there is no requirement that a limitation be express. See State v. Osborne, 14 Ariz. 185, 206, 125 P. 884, 893 (1912) (holding that an act may be repugnant to the constitution even where [521]*521there is “no express prohibition.”) A limitation may be implied by the text of the constitution or its structure taken as a whole.
¶ 15 For example, in Sawyer v. LaSota, 119 Ariz. 253, 254, 580 P.2d 714, 715 (1978), we were asked to decide whether the legislature could require that the Attorney General be admitted to the state bar for five years preceding the date of taking office. Article V, section 2 of the constitution did not list that as a qualification for the office. We said:
In a continuous line of cases commencing over 60 years ago, it has been held that the Legislature has no power to add new or different qualifications for a public office other than those specified in the Constitution.
Id. at 256, 580 P.2d at 717. We concluded that the statute was unconstitutional because it provided an additional qualification not required by the constitution. Id. This is an implied, not an express, limitation on legislative power.
¶ 16 LaSota relied upon Whitney v. Bolin, 85 Ariz. 44, 47, 330 P.2d 1003, 1005 (1958), for the proposition that:
the enumeration of certain specified things in a constitution will usually be construed to exclude all other things not so enumerated. Positive directions in a constitution contain an implication against anything contrary to them.
(emphasis added). The question in Whitney was whether a “resign to run” statute would apply to a judge of the superior court when that judge became a candidate for the Supreme Court of Arizona. Id. at 46, 330 P.2d at 1004. We looked to the constitution describing the qualifications for judges of the supreme court. Superior court judges were not excluded. We said that “the power of the legislature is plenary and unless that power is limited by express or inferential provisions of the Constitution, the legislature may enact any law which in its discretion it may* desire.” Id. at 47, 330 P.2d at 1004 (emphasis added). We held that the statute could not apply to a judge of the superior court because it would in effect be adding to constitutional qualifications.
¶ 17 We did not limit this view to qualifications for office. The basis for the holding was the more general “accepted constitutional construction that the enumeration of certain specified things in a constitution will usually be construed to exclude all others not so enumerated. Positive directions in a constitution contain an implication against anything contrary to them.” Id. at 47, 330 P.2d at 1005 (emphasis added). Whitney thus acknowledged that constitutional limitations may be implied as well as express, and that this is a general rule not limited to qualifications for office.
¶ 18 And in Hudson v. Kelly, 76 Ariz. 255, 263, 263 P.2d 362, 367 (1953), we relied on Cooley’s Constitutional Limitations to reject the proposition that the constitution contains no implied limitations.2 We adopted the following, which Cooley, in turn, adopted from the New York Court of Appeals: “The frame of the government, the grant of legislative power itself, the organization of the executive authority, the erection of the principal courts of justice, create implied limitations upon the law-making authority as strong as though a negative was expressed in each instance.” Id.
¶ 19 Neither Cox nor Frohmiller is inconsistent with the doctrine of implied limitations. They just had no need to address it. In Cox, for example, in extending the appellate jurisdiction of the superior court from inferior courts to administrative agencies, the legislature was doing something consistent with and not in conflict with the constitution. The extension was within the scope of article VI. So, too, in Frohmiller, providing per diem expenses to legislators was not inconsistent with that part of the constitution [522]*522which provided for legislative compensation. Instead, it was in aid of it.
¶ 20 But in the instant case, we have something very different. In contrast to Cox, this is not a case of enlarging a preexisting judicial power. By involving the Commission on Appellate Court Appointments in activities wholly unrelated to the nomination and appointment of appellate judges, the Act violates limitations implied by the constitution itself. This is not a ease of legislative enactment in the face of a silent constitution. In such eases, the legislature can ordinarily act. But here, the constitution is quite express. It creates a commission whose sole function is to screen and nominate candidates for judicial office.
¶ 21 We do not, of course, suggest that the screening and nomination of judicial candidates may be characterized as a judicial function. The Commission does not adjudicate disputes, nor was it conceived or established as an adjudicative body; indeed, by the screening and nomination of judicial candidates, the Commission partakes in a process that is otherwise assigned to the executive department. And yet the Commission was neither established as a free-floating screening body for gubernatorial appointees nor placed within the executive department under article V. Rather, it was confined within article VI as an entity of the judicial department. Its title bespeaks its single function— it is the Commission on Appellate Court Appointments. And as we have indicated, although the constitution expressly grants the legislature authority to enlarge the powers and duties of other constitutional officers and bodies, the constitution makes no such grant of authority with respect to the Commission.
¶ 22 By giving it functions wholly alien to its constitutional charter, A.R.S. § 16-955(B) and (C) violate the constitution. The Act is simply incompatible with article VI, sections 36 and 37. We thus agree with the superior court that those portions of the Act which expand the duties of the Commission on Appellate Court Appointments beyond the scope of judicial appointments are inconsistent with the Arizona Constitution.
III.
Severability — Commission on Appellate Court Appointments
¶23 Citizens for Clean Elections Commission and Arizonans for Clean Elections argue that even if part of the Act is unconstitutional, that part is severable and the remainder of the Act can function. They note that the Act has an express severability provision in it. A.R.S. § 16-960.3 They also rely on Randolph v. Groscost, 195 Ariz. 423, 989 P.2d 751 (1999), in which we articulated a variation on the severability test for legislative measures that are begun by initiative. Under this test, we ask whether the valid portion can operate without the unconstitutional provision and, if so, we will uphold it unless the result is so absurd or irrational that one would not have been adopted without the other. Id. at 427, 989 P.2d at 755.
¶ 24 It appears to us that the Act will work without the Commission on Appellate Court Appointments. By severing all references to the Commission on Appellate Court Appointments, the statewide officers in whom the appointment power is vested will make appointments, subject to statutory standards, A.R.S. § 16-955(B), but without a slate of candidates. The statewide officers who make appointments must select persons “who are committed to enforcing [the Act] in an honest, independent, and impartial fashion and to seeking to uphold public confidence in the integrity of the electoral system.” A.R.S. § 16-955(B). Appointments will be made by officers of alternating political parties. The appointees cannot have, in the previous five years, “been appointed to, been elected to, or run for any public office, including precinct committeeman, or served as an officer of a political party.” Id. Thus, [523]*523the Clean Elections Commission will be no less non-partisan without the involvement of the Commission on Appellate Court Appointments. We easily conclude that the valid portions of the Act considered separately can operate independently and are workable.4
¶ 25 Nor is the result so irrational or absurd as to compel the conclusion that an informed electorate would not have adopted one portion without the other. Randolph, 195 Ariz. at 427, 989 P.2d at 755. Had the electorate enacted the Act without the Commission on Appellate Court Appointments, or any other screening body, we could not conclude that the legislation was irrational. The people could have selected such a regime and it would have passed the rational basis test for due process violations. Indeed, the express severability clause, ante at ¶23, n. 3, informs us that all doubts are to be resolved in favor of severability. We thus disagree with the trial court on this issue and hold that the offending portions of the Act relating to the Commission on Appellate Court Appointments are severable. We hereby sever only those portions of A.R.S. § 16-955 that involve the Commission on Appellate Court Appointments.
IV.
Senatorial Concurrence in Removal
¶ 26 Under the Act, A.R.S. § 16-955(E), the Governor may remove members of the Citizens Clean Elections Commission only for cause and only with the concurrence of the senate. The trial court concluded that this violated the doctrine of separation of powers.
¶ 27 The power of removal, like the power to appoint, is not expressed in the Arizona Constitution. But we have held, consistently with the doctrine of implied limitations on the exercise of legislative power discussed ante, that the Governor’s duty to take care that the laws be faithfully executed under article V, section 4, includes the power to remove subordinates. Ahearn v. Bailey, 104 Ariz. 250, 253, 451 P.2d 30, 33 (1969). This is an implied limitation on the legislature’s power. In Aheam, we concluded that while the legislature may define the causes for removal, it could not directly remove a public officer except by impeachment. Id.
¶ 28 The Act does not purport to allow the legislature to remove a member of the commission. But it does condition the Governor’s power to remove upon the senate’s concurrence. We acknowledge that senate concurrence in removal is more intrusive than senate concurrence in appointment. This is so because if the senate chooses not to approve a gubernatorial appointment, the Governor may try again. But if the senate does not concur in the removal of a public officer by the Governor, the Governor, if she is the appointing officer, is left with that person. If that person was someone under the direct control and supervision of the Governor, or someone whose cooperation was vital to the Governor’s exercise of her own constitutional powers, we would not hesitate to conclude that senatorial concurrence would unduly interfere with an exercise of an executive power and thus violate the doctrine of separation of powers. See Ahearn, 104 Ariz. at 253, 451 P.2d at 33 (“The Governor ... must ... have the power to select subordinates and to remove them if they are unfaithful.”) (emphasis added).
¶ 29 But this case is different. The members of the Citizens Clean Elections Commission, once appointed by the Governor or any other state official, are not subject to gubernatorial supervision or control. They are not part of the executive team. They are not subordinates of the Governor or any other official who may have appointed them. Indeed, the statute requires that they act quite independently of elected officials. A.R.S. § 16-955(B). In addition, their powers under the Act are limited to voter education and enforcement. ' A.R.S. § 16-956.
¶ 30 In State ex rel. Woods v. Block, 189 Ariz. 269, 276, 942 P.2d 428, 435 (1997), we subscribed to a four-part test to evaluate separation of powers claims: (1) the nature of the power being exercised; (2) the degree [524]*524of control of another branch; (3) the purpose of the legislation; and (4) the practical consequences of the action. From what we have said so far, we believe that the provision for senatorial concurrence in the removal of members of the Citizens Clean Elections Commission does not violate the doctrine of separation of powers. The power being exercised, concurrence, unlike removal, is not an executive power. The degree of control is minimal. The purpose is cooperative. There has, as yet, been no consequence.
V.
Appointments made by Supreme Court Justices
¶31 VotePac’s argument that the Chief Justice’s role as chair of the Commission on the Appellate Court Appointments itself violates separation of powers is mooted by our holding that the involvement of the Commission on Appellate Court Appointments is unconstitutional. Ante, at ¶22. This leaves for consideration VotePac’s argument that it is a violation of the doctrine of separation of powers to allow members of the Supreme Court of Arizona to make appointments to the Citizens Clean Elections Commission.
¶ 32 Article VI of the Arizona Constitution vests judicial power in the judicial branch of government. Ariz. Const, art. VI, § 1. It describes the qualifications of members of this court, article VI, section 6, and defines our jurisdiction and functions. Ariz. Const, art. VI, § 5. Unlike the executive and legislative branches, the judicial branch is purposely non-political. Under merit selection and retention, the justices of this court do not sit as members of political parties. They are nominated and appointed “without regard to political affiliation.” Ariz. Const, art. VI, § 36(D) and § 37(C). Yet, the Act not only purports to involve the members of this court in the appointment of members to the Citizens Clean Elections Commission but it does so based upon their party affiliation.
¶ 33 Three problems immediately arise. First, the appointment power is an executive function, not a judicial function. See Block, 189 Ariz. at 277, 942 P.2d at 436. Second, the Citizens Clean Elections Commission has functions wholly unrelated to the judicial power vested in this court under article VI of the constitution. (Implied limitations again). Third, whether a particular member of this court makes an appointment is a direct function of that member’s political party affiliation, which is directly contrary to article VI, section 36(D) and section 37(C) that the members of this court do not sit as Republicans, Democrats or anything else in their capacity as justices. For all of these reasons, it is clear enough to us that to the extent that the Act includes members of this court as officials who may appoint members of the Citizens Clean Elections Commission, A.R.S. § 16-955(0, it is unconstitutional.
¶ 34 This is such a small and insignificant part of the Act, however, that we can say with confidence this portion is severable under Randolph (it works without it and the remainder is not irrational). We hereby sever it.5
VI.
Title of the Act
¶ 35 In Meyers v. Bayless, 192 Ariz. 376, 378, 965 P.2d 768, 770 (1998), we upheld the title “Citizens Clean Elections Act” under article IV, part 1, section 1(9) of the constitution. VotePac now argues that the title is insufficient under article IV, part 2, section 13 of the constitution. VotePac acknowledges that in Iman v. Bolin, 98 Ariz. 358, 365, 404 P.2d 705, 710 (1965) we held that article IV, section 13 applies only to the acts of the legislature, and not to initiative measures. Nevertheless, VotePac argues that article IV, section 13 should apply to initiatives after their enactment. But it either applies or it does not — the timing cannot matter.
¶ 36 VotePac also seeks to limit the effect of Iman to initiatives proposing constitution[525]*525al amendments. But the initiative in Iman was not a constitutional amendment. We decline to give Iman such a narrow reading. We affirm Iman for the proposition that article IV, part 1, section 1(9) applies to initiatives and article IV, part 2, section 13 applies to bills. Thus article IV, part 2, section 13 does not apply to the Act.
VII.
Conclusion
¶ 37 Those provisions of the Citizens Clean Elections Act that purport to involve the Commission on Appellate Court Appointments are unconstitutional and are hereby severed from the Act. That provision of the Act that purports to involve members of this court in the appointment of members to the Citizens Clean Elections Commission is unconstitutional and is hereby severed from the remainder of the Act. The order of the trial court is vacated. The case is remanded to the trial court for entry of judgment consistent in all respects with this opinion.
