JUSTICE TIMMER, opinion of the Court:

¶1             In 1998, Arizona voters enacted the Citizens Clean Elections
Act to establish public funding for political candidates in statewide and
state legislative elections. The Act prohibits a candidate who opts not to
receive public funding from accepting contributions greater than eighty
percent of the campaign contribution limits specified in A.R.S. § 16-905.
The issue here is whether the Act fixes campaign contribution limits at
eighty percent of the amounts that existed in 1998 or instead provides a
formula for calculating limits. We hold that the Act provides a formula
for calculating contribution limits.

                     Opinion of the Court

                            I. BACKGROUND

¶2            Both Arizona voters and the legislature have taken an active
role in developing campaign financing laws. In 1986, voters enacted by
initiative A.R.S. § 16-905, which established campaign contribution limits
for state, county, and local elected officials. The legislature amended § 16-
905 in 1993, 1994, 1997, and 2007 to increase those limits. 1993 Ariz. Sess.
Laws, ch. 226, § 4 (1st Reg. Sess.); 1994 Ariz. Sess. Laws, ch. 379, § 2 (2d
Reg. Sess.); 1997 Ariz. Sess. Laws, ch. 201, § 6 (1st Reg. Sess.); 2007 Ariz.
Sess. Laws, ch. 277, § 1 (1st Reg. Sess.).

¶3             In 1998, voters passed an initiative to create the Citizens
Clean Elections Act, A.R.S. §§ 16-940 to -961 (“CCEA” or “Act”), which
established an alternative campaign financing system for primary and
general elections and created the Citizens Clean Elections Commission to
administer it. Under this system, candidates for statewide and state
legislative offices who agree to limit fundraising and campaign spending
(“participating candidates”) receive public campaign financing. Eligible
candidates who choose not to participate (“nonparticipating candidates”)
can accept private campaign contributions up to eighty percent of the
limits established by A.R.S. § 16-905(A)–(E), as adjusted periodically for
inflation. A.R.S. § 16-941(B). In an apparent effort to “level the playing
field,” the Act also originally provided that once expenditures by or on
behalf of a nonparticipating candidate exceeded a publicly funded
opponent’s initial funding allotment, that opponent would be given
roughly one dollar for every additional dollar spent by or on behalf of the
nonparticipating candidate, capped at three times the initial public
funding allotment.1 A.R.S. § 16-952 (1998); see Bennett, 131 S. Ct. at 2813.
Candidates for countywide and municipal offices are not eligible to
participate in the Clean Elections system.

¶4         In 1998, the voters also passed another initiative, unrelated
to the CCEA, which adopted the Voter Protection Act (“VPA”). Ariz.

1      The United States Supreme Court invalidated this “matching funds
scheme” because it violated the First Amendment by substantially
burdening protected political speech without serving a compelling state
interest. Ariz. Free Enter. Club’s Freedom Club PAC v. Bennett, 131 S. Ct.
2806, 2813 (2011).

                      V. BRAIN (BENNETT)
                      Opinion of the Court

Const. art. 4, pt. 1, § 1(6). The VPA limits the legislature’s authority to
modify laws enacted by voters at or after the November 1998 general
election. Cave Creek Unified Sch. Dist. v. Ducey, 233 Ariz. 1, 4 ¶ 9, 308 P.3d
1152, 1155 (2013); Ariz. Const. art. 4, pt. 1, § 1, Historical Notes (West
2014).

¶5            In April 2013, the legislature passed and the Governor
signed House Bill (“H.B.”) 2593, which amended § 16-905 by increasing
campaign contribution limits for statewide, countywide, and local offices,
eliminating restrictions on the aggregate amount of money candidates can
receive from political committees, and eliminating restrictions on the
amount of money individuals can contribute to political committees that
give money to candidates. 2013 Ariz. Sess. Laws, ch. 98, § 2 (1st Reg.
Sess.). The effective date for H.B. 2593 was September 13, 2013.

¶6            In July 2013, the Citizens Clean Elections Commission and
others (collectively, the “Commission”) sued Arizona’s Secretary of State,
asking the superior court to declare H.B. 2593 unconstitutional, as
applicable to nonparticipating candidates, and to enjoin the Secretary
from implementing it. The Commission alleged that the CCEA fixed
campaign contribution limits as they existed in 1998 for nonparticipating
candidates, and that the legislature could not alter those limits by
amending § 16-905 without complying with the VPA. The court permitted
the President of the Senate, Andy Biggs, and the Speaker of the House,
Andrew M. Tobin, (collectively, “Intervenors”) to intervene and join in
defending H.B. 2593.

¶7             The superior court denied the Commission’s motion to
preliminarily enjoin implementation of H.B. 2593, finding that the
Commission did not have a strong likelihood of success on the merits. See
Shoen v. Shoen, 167 Ariz. 58, 63, 804 P.2d 787, 792 (App. 1991) (setting forth
factors to consider in ruling on a motion for preliminary injunction). The
court reasoned that § 16-905 is probably not subject to the VPA because (1)
the CCEA referred to § 16-905 only as part of a formula for computing
contribution limits, (2) subjecting cross-referenced statutes to the VPA
could “create havoc,” and (3) it was uncertain whether a majority of voters
in 1998 intended that the VPA apply to the CCEA. The court also found
that, “in light of . . . First Amendment issues presented” by Intervenors, it


                                      4
        ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                      V. BRAIN (BENNETT)
                      Opinion of the Court

could not conclude that irreparable harm would occur or that the balance
of hardships or public interest favored a preliminary injunction.

¶8            In an ensuing special action, the court of appeals accepted
jurisdiction and granted relief to the Commission. Ariz. Citizens Clean
Elections Comm’n v. Brain, 233 Ariz. 280, 282 ¶ 1, 311 P.3d 1093, 1095 (App.
2013). The court did not address the parties’ VPA-related or First
Amendment arguments. Instead, it held that, “as a matter of statutory
construction, when the voters enacted the [CCEA] in 1998, they fixed
campaign contribution limits as they existed in 1998 . . . [and] did not
adopt a mere formula that would allow the Legislature to easily amend
the § 941 limits.” Id. at 288 ¶ 31, 311 P.3d at 1101. Based on that
determination, the court of appeals further concluded that because § 16-
941(B) applies “[n]otwithstanding any law to the contrary,” it “preempts”
and renders “ineffective” those provisions of H.B. 2593 that altered
campaign contribution limits applicable to nonparticipating candidates.
Id.

¶9            In light of its interpretation of § 16-941(B) as providing fixed
limits rather than a formula, the court of appeals vacated the superior
court’s order denying the Commission’s motion for a preliminary
injunction. Id. at 290–91 ¶ 41, 311 P.3d at 1103–04. Because the superior
court acknowledged but did not sufficiently address Intervenors’
arguments that fixed limits violate the First Amendment, however, the
court of appeals instructed the superior court to revisit that issue. Id.
Pending that determination, the court of appeals maintained the
preliminary injunction against H.B. 2593’s implementation, as applicable
to nonparticipating candidates. Id. at 292 ¶ 46, 311 P.3d at 1105.

¶10           Pursuant to our jurisdiction under Article 6, Section 5(3) of
the Arizona Constitution, and as a matter of statewide importance, we
granted review to decide this single statutory issue: whether A.R.S. § 16-
941(B) provides a formula for calculating campaign contribution limits for
nonparticipating candidates or instead fixes those limits. We previously
vacated the court of appeals’ opinion and lifted the preliminary
injunction, indicating that this opinion would follow.

                      Opinion of the Court

                             II. DISCUSSION

¶11            Our primary objective in interpreting a voter-enacted law is
to effectuate the voters’ intent. See Ariz. Early Childhood Dev. & Health Bd.
v. Brewer, 221 Ariz. 467, 470 ¶ 10, 212 P.3d 805, 808 (2009). If the statute is
subject to only one reasonable interpretation, we apply it as written
without further analysis. Id. But if the statute is ambiguous, we consider
secondary principles of statutory interpretation, such as “the context of
the statute, the language used, the subject matter, its historical
background, its effects and consequences, and its spirit and purpose.”
Wyatt v. Wehmueller, 167 Ariz. 281, 284, 806 P.2d 870, 873 (1991) (citation
omitted). We review the interpretation of statutes de novo as an issue of
law. State v. Gutierrez, 229 Ariz. 573, 576 ¶ 19, 278 P.3d 1276, 1279 (2012).

                                      A.

¶12            Before addressing the statutory issue before us, we make
clear that two factors have no bearing on determining the voters’ intent
when they passed the CCEA in 1998: the VPA and testimony from
plaintiff Louis J. Hoffman, who primarily drafted the CCEA and served as
a member of the Citizens Clean Elections Commission. Although voters
approved both the VPA and the CCEA in the 1998 general election, the
acts’ subjects are not linked, and nothing in the CCEA’s publicity
pamphlet or ballot language mentions the VPA. In short, those who voted
to enact the CCEA might or might not have supported the VPA and could
not have counted on its simultaneous enactment. And just as a legislator,
lobbyist, or other interested party lacks competence to testify about
legislative intent in passing a law, Golder v. Dep’t of Revenue, 123 Ariz. 260,
265, 599 P.2d 216, 221 (1979), the drafter of a voter initiative is not
competent to testify about the voters’ intent in passing that initiative.

                                      B.

                                      1.

¶13          We begin our statutory analysis with the language of A.R.S.
§ 16-941(B):




                                      6
        ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                      V. BRAIN (BENNETT)
                      Opinion of the Court

              Notwithstanding any law to the contrary, a
       nonparticipating candidate shall not accept contributions in
       excess of an amount that is twenty per cent less than the
       limits specified in § 16-905, subsections A through E, as
       adjusted by the secretary of state pursuant to § 16-905,
       subsection H. Any violation of this subsection shall be
       subject to the civil penalties and procedures set forth in § 16-
       905, subsections J through M and § 16-924.2

That subsection can be reasonably read as either providing a formula for
calculating campaign contribution limits for nonparticipating candidates,
applicable as the amounts prescribed in § 16-905 change (as Intervenors
argue and the superior court determined) or fixing those limits at eighty
percent of the amounts listed in § 16-905 at the time of the 1998 election (as
the Commission argues and the court of appeals held). Therefore, the
statute is ambiguous.

                                       2.

¶14          Application of secondary principles of statutory construction
reveals support for each competing interpretation of § 16-941(B). For the
reasons stated below, however, we are convinced that the statute is most
reasonably interpreted as establishing a formula.

¶15          First and foremost, the voters used a percentage for
calculating contribution limits for nonparticipating candidates.
Application of a percentage to a given amount is characteristic of a
formula. See Random House Webster’s Unabridged Dictionary 753 (2d
ed. 2001) (defining “formula” in part as “a set form of words . . . for
indicating procedure to be followed”). Had voters intended to fix static
contribution limits, they could have easily and clearly done so by
specifying dollar amounts. Cf. McElhaney Cattle Co. v. Smith, 132 Ariz. 286,
290–91, 645 P.2d 801, 805–06 (1982) (reasoning that if the electorate had

2      The legislature has amended the CCEA, including § 16-941(B), in
ways that do not affect the issue before us. See 2007 Ariz. Sess. Laws, ch.
277, § 2 (1st Reg. Sess.); 2009 Ariz. Sess. Laws, ch. 114, § 8 (1st Reg. Sess.);
2012 Ariz. Sess. Laws, ch. 290, § 2 (2d Reg. Sess.). We therefore cite the
current version of the Act, unless otherwise indicated.
                                       7
        ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                      V. BRAIN (BENNETT)
                      Opinion of the Court

intended to include cattle raisers or farmers within the meaning of
“wholesaler” in tax exemption, “it is difficult to believe that (they) would
have attempted to carry it into effect in such an uncertain and doubtful
manner, when (they) could have done so easily and naturally”) (citation
and internal quotation marks omitted).

¶16            Indeed, the voters fixed monetary amounts in other parts of
§ 16-941 and elsewhere in the CCEA. See A.R.S. §§ 16-941(A)(2) (personal
expenditure limits); -941(D) (independent expenditure reporting); -942(B)
(civil penalties); -944 (lobbyist fees); -945(A) (early contributions limits); -
948(C) (petty cash restrictions); -954(B) (tax reduction); -955(G)
(commissioner compensation); and -961(G) (primary election spending
limits). Even assuming, as the dissent suggests, that the Act’s drafters
might have chosen to refer to § 16-905 for ease of reference rather than
listing contribution limits in § 16-941(B), Dissent ¶ 41, it defies common
sense to conclude that voters, who had no role in the drafting process,
were similarly motivated. In short, no sound reason exists to conclude
that voters intended to establish fixed contribution limits in § 16-941(B) by
using a percentage formula that expressly incorporates another, existing
statute, § 16-905.

¶17            Second, voters treated the § 16-941(B) limits differently from
fixed amount limits specified elsewhere in the Act. Specifically, voters
included an inflation-adjustment mechanism for monetary amounts fixed
in other provisions of the Act, including § 16-941(A)(2) and (D), but they
did not do so for § 16-941(B). See A.R.S. § 16-959. Instead, § 16-941(B)
provides that the inflation-adjustment mechanism in § 16-905 applies. The
fact that voters treated the § 16-941(B) limits differently from fixed amount
limits further suggests that the voters did not intend to fix monetary limits
in § 16-941(B). Cf. Fidelity Nat. Fin. Inc. v. Freidman, 225 Ariz. 307, 310 ¶ 12,
238 P.3d 118, 121 (2010) (acknowledging that statutes relating to the same
subject should be construed together); Farmers Co-op. Co. v. DeCoster, 528
N.W.2d 536, 539 (Iowa 1995) (“[W]here a statute with respect to one
subject contains a given provision, the omission of such provision from a
similar statute is significant to show a different intention existed.”)
(citation omitted).

¶18          Third, interpreting § 16-941(B) as fixing contribution limits
for nonparticipating candidates at eighty percent of 1998 levels would

                                       8
        ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                      V. BRAIN (BENNETT)
                      Opinion of the Court

widen the voter-approved gap between these limits and those for
candidates not subject to the Act. Voters in 1998 constructively knew that
the legislature would at some point likely amend § 16-905 to increase
campaign contribution limits, as it had done three times in the preceding
twelve years, including the year before the election. Because § 16-941(B)
applies “notwithstanding any law to the contrary,” fixed limits for
nonparticipating candidates would remain in place, and increased limits
would apply only to candidates not subject to the Act. Although the
voters intended a twenty-percent gap between limits for nonparticipating
candidates and candidates not subject to the CCEA, nothing indicates that
voters wanted to widen this gap.

¶19           To illustrate, under § 16-905’s current limits, an individual
could contribute $5,000 to a city council candidate for primary and general
elections. But if § 16-941(B) fixes limits at eighty percent of 1998 levels for
nonparticipating candidates, that individual could not contribute more
than approximately $1,850 to a nonparticipating gubernatorial candidate
who must run a more expensive statewide campaign.3 Compare A.R.S.
§ 16-905 (A)(2), with id. §§ 16-905(B)(1), -941(B) (1998). Under this scenario,
a sixty-seven percent gap is created between contribution limits for
nonparticipating candidates and those for candidates not subject to the
CCEA. Interpreting § 16-941(B) as providing a formula that increases

3       We approximated the $1,850 figure by calculating eighty percent of
the limits specified by § 16-905 in 1998 and adjusting that figure for
inflation based on the Secretary of State’s post-1998 adjustments to § 16-
905’s limits.

        Our illustration does not consider the 2007 amendments to § 16-
905’s limits. The legislature amended § 16-905 to increase limits, but it did
not repeal, reenact, or substantively amend § 16-941(B). 2007 Ariz. Sess.
Laws, ch. 277, § 2 (1st Reg. Sess.). Therefore, if § 16-941(B) fixes limits at
eighty percent of 1998 levels, because that provision applies
“notwithstanding any law to the contrary,” the 2007 amendments to § 16-
905 did not change contribution limits for nonparticipating candidates.
Although we do not decide the efficacy of the 2007 amendments, we refer
to 1998 limits in our illustration.



                                      9
        ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                      V. BRAIN (BENNETT)
                      Opinion of the Court

contribution limits for nonparticipating candidates as § 16-905 is amended
prevents such anomalies and maintains the voter-approved twenty-
percent gap. Cf. Gutierrez v. Indus. Comm’n of Ariz., 226 Ariz. 395, 396–97
¶ 6, 249 P.3d 1095, 1096–97 (2011) (acknowledging preference to interpret
a statute to give it “a fair and sensible meaning”) (citation and internal
quotation marks omitted).

¶20            Fourth, interpreting § 16-941(B) as providing fixed limits
creates a needlessly confusing system, which the voters also likely did not
intend. Section 16-941(B) provides that the eighty percent contribution
limits are calculated from the amounts specified in § 16-905 “as adjusted
by the secretary of state pursuant to § 16-905, subsection H.” Section 16-
905(H) requires the Secretary of State to adjust for inflation the amounts in
§ 16-905 biennially. Because nothing requires the Secretary to adjust 1998-
established limits for nonparticipating candidates following the
legislature’s changes to the § 16-905 limits, it is uncertain whether and
how the § 16-941(B) limits would be adjusted for inflation. Interpreting
§ 16-941(B) as prescribing a formula eliminates that uncertainty.

¶21            Fifth, and finally, nothing in the ballot or attendant publicity
pamphlet for the 1998 election informed voters that § 16-941(B)
permanently fixed contribution limits at eighty percent of 1998 levels. See
Ruiz v. Hull, 191 Ariz. 441, 450 ¶ 36, 957 P.2d 984, 993 (1998) (“In
construing an initiative, we may consider ballot materials and publicity
pamphlets circulated in support of the initiative.”) (citation omitted). The
ballot stated that one effect of the CCEA would be to “reduc[e] the current
contribution limits by 20% for non-participating candidates.” Similarly,
the pamphlet advised that the Act would “reduce by twenty percent the
amount per individual that can currently be contributed to a candidate.”
These statements accurately described the immediate impact of the CCEA,
no matter whether § 16-941(B) prescribed a formula or a fixed amount.
Significantly, nothing alerted voters that the percentage reduction in § 16-
941(B) would apply only to then-existing limits in § 16-905, or that any
future increases in contribution limits under § 16-905 would not apply to
nonparticipating candidates. Were that intended, we would expect a clear

                      Opinion of the Court

                                      3.

¶22           We do not address every argument supporting a contrary
interpretation of § 16-941(B). Even if some of those arguments are
persuasive, the most reasonable interpretation remains that § 16-941(B)
prescribes a formula. Nevertheless, we address the main points advanced
by the Commission and adopted by the court of appeals and, to some
extent, our dissenting colleagues.

¶23            The directive that § 16-941(B) apply “[n]otwithstanding any
law to the contrary” does not evidence an intent to fix contribution
amounts for nonparticipating candidates at 1998 levels regardless of any
future alterations to § 16-905’s limits. See Brain, 233 Ariz. at 286 ¶ 19, 311
P.3d at 1099 (reasoning that inclusion of this phrase reflects the voters’
intent that § 16-941(B) “stand on its own” and “have significance separate
and apart from . . . § 16-905”). Rather, by providing that § 16-941(B)
applies “notwithstanding” other laws, voters ensured that the twenty-
percent reduction to § 16-905’s limits applies regardless of any future
adjustments to those limits and regardless of any contrary laws.

¶24             Inclusion of the inflationary-adjustment language in § 16-
941(B) does not evidence the voters’ intent to permit only the Secretary of
State to adjust limits for nonparticipating candidates. Nor is that language
superfluous if, as we conclude, § 16-941(B) prescribes a formula. See Brain,
233 Ariz. at 286 ¶ 18, 311 P.3d at 1099. Absent that language, the twenty-
percent reduction would apply to the limits established by § 16-905(A)–(E)
without periodic inflationary adjustments. Inclusion of the language
clarifies that the adjustments required by § 16-905(H) apply. Significantly,
§ 16-941(B) neither states that inflationary adjustments are the only
changes that may be made to contribution limits nor forecloses
calculations of new limits if the legislature amends § 16-905.

¶25           Section 16-941(B) is not rendered “illusory” or “virtually
meaningless” if the voters intended to prescribe a formula any more than
if they intended to fix limits. Dissent ¶ 39; Brain, 233 Ariz. at 287 ¶ 23, 311
P.3d at 1100. When voters enacted the CCEA, pre-VPA law in effect at
that time prohibited the legislature from repealing or modifying a voter-
approved law only if it was enacted by a majority of all registered voters,
not merely a majority of those who voted on the measure — an unlikely

scenario. See Cave Creek Unified Sch. Dist., 233 Ariz. at 4 ¶ 9, 308 P.3d at
1155. Thus, as far as 1998 voters knew, just as the legislature could have
responded to the twenty-percent reduction in § 16-941(B) by increasing
the limits in § 16-905 by twenty percent, under then-current law it could
have amended § 16-941(B) to increase any fixed amount or to completely
remove any limits. By providing a twenty-percent reduction formula
rather than a fixed amount, voters increased the chances that § 16-941(B)
would remain viable after any increases to § 16-905’s limits and
consequently would continue to serve as an incentive for candidates to
participate in the CCEA.

¶26            We reject the dissent’s assertion that voters likely intended
to fix contribution limits in § 16-941(B) because “[p]ublic funding
allotments under the CCEA are not tied to the contribution limits for non-
participating candidates,” and so a formula would make public funding
“less appealing as it becomes easier for candidates to receive large private
contributions.” Dissent ¶ 45. At the time voters passed the CCEA
initiative, the now-defunct matching-funds provision existed to ensure
that public funding kept pace with private contributions up to “three
times the original spending limit” for participating candidates in both the
primary and general elections. A.R.S. § 16-952(E) (1998). In light of this
generous matching provision, the voters did not have to fix contribution
limits to entice candidates to opt into the Act and accept public funding.

¶27           Nelson Machinery Co. v. Yavapai County, 108 Ariz. 8, 491 P.2d
1132 (1971), on which the court of appeals relied, does not persuade us to
interpret § 16-941(B) differently. See Brain, 233 Ariz. at 287 ¶ 24, 311 P.3d
at 1100. In Nelson Machinery, this Court cited a statutory construction
canon providing that when a statute adopts another statute by specific
reference, the adopted statute is taken as it then exists and does not
include subsequent amendments, unless the enactors of the adopting
statute expressly intended otherwise. Nelson Mach., 108 Ariz. at 9, 491
P.2d at 1133. Apparently recognizing the canon’s limitations, the Nelson
Machinery Court neither embraced nor applied it, turning instead to other
factors to determine a contrary legislative intent. Id. at 9–10, 491 P.2d at
1133–34. Similarly, because the canon does not help ascertain the voters’
intent, and in light of the evidence indicating that the voters intended



                                     12

§ 16-941(B) to provide a formula, we likewise decline to apply the canon
here.4
                                   III.

¶28           For the foregoing reasons, the most reasonable
interpretation of A.R.S. § 16-941(B) is that voters intended to prescribe a
formula to calculate campaign contribution limits for nonparticipating
candidates for statewide and state legislative offices. Because the court of
appeals reached a contrary conclusion, we vacate its opinion and affirm
the superior court’s order denying the Commission’s motion for a
preliminary injunction.




4       Some state legislatures have, in our view helpfully, enacted a
specific rule of construction for statutes that incorporate by reference other
statutes. See, e.g., Colo. Rev. Stat. Ann. § 2-4-209 (West 2014) (“A reference
to any portion of a statute applies to all reenactments, revisions, or
amendments thereof.”); Cal. Gov’t Code § 9 (West 2014) (“Whenever
reference is made to any portion of this code or any other law of this State,
the reference applies to all amendments and additions now or hereafter
made.”); see also F. Scott Boyd, Looking Glass Law: Legislation by Reference in
the States, 68 La. L. Rev. 1201, 1247–48 (2008).

VICE CHIEF JUSTICE BALES, with whom CHIEF JUSTICE BERCH joins,
dissenting:

¶29           Seeking to reform the financing of campaigns for the
legislature and certain state offices, Arizona’s voters approved the CCEA
in 1998 to provide public funding for participating candidates and to
reduce the contribution limits for non-participating candidates to “twenty
per cent less than the limits specified in § 16-905.” A.R.S. § 16-941(B).
Since the CCEA was adopted, many have questioned its premises and
effectiveness, and some of its provisions have been challenged as contrary
to the First Amendment. Whether the CCEA is desirable as a policy
matter or vulnerable to further constitutional challenges are not issues
before this Court, and I express no view regarding them.

¶30            The issue we must decide is whether the voters in 1998
intended to reduce the contribution limits to eighty percent of the limits
then specified in § 16-905 (i.e., the limits reduced by twenty percent) or
instead to adopt a formula that would automatically ratchet up the limits
to eighty percent of whatever amounts the legislature might set. The
majority adopts the latter interpretation, thereby approving the
legislature’s recent increases to the individual contribution limits (among
others) by more than 400 percent for statewide candidates (from $912 to
$4000 for each election cycle) and more than 900 percent for legislative
candidates (from $440 to $4000). I respectfully dissent because construing
A.R.S. § 16-941(B) to refer to the “limits specified in § 16-905” when the
CCEA was adopted better effects the intent of the voters, who plainly
sought to reduce the impact of large campaign contributions in Arizona
elections.

¶31            In analyzing the issue presented, I agree with many of the
conclusions reached by the majority, although sometimes for different
reasons. I agree that the voters’ approval of the VPA in the 1998 election
is not relevant to the issue presented. Op. ¶ 12. But I disagree with the
majority’s observations that the VPA is “not linked” to the CCEA because
the latter’s supporters “might or might not have supported the VPA.” Id.

¶32          The two Acts are indeed “linked.” The VPA applies to
measures “decided by the voters at and after the November 1998 general
election.” Proposition 105, § 2, 1999 Ariz. Sess. Laws 1937, 1941. Thus, by

                                    14
       ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                     V. BRAIN (BENNETT)
               VICE CHIEF JUSTICE BALES, Dissenting

approving the VPA, a majority of the voters contemplated that it would
apply to other measures approved at the 1998 election, even though they
may not have then known that particular measures such as the CCEA
would be approved.

¶33            The VPA is irrelevant here for a different reason. If the
majority is correct that the voters intended a formula, then the
legislature’s increasing the limits by amending § 16-905 would comport
with the CCEA, and the VPA would not be implicated. Conversely, if the
voters intended to adopt limits based on the then-existing amounts set in
§ 16-905, any change in the contribution limits for non-participating
candidates would have to comply with the VPA’s requirements, including
approval by at least three-fourths of each house of the legislature.
(Indeed, the legislature arguably complied with these requirements when
it increased the contribution limits previously in 2007.) But the existence
of the VPA does not help in resolving whether the voters contemplated
that the CCEA, by referencing the § 16-905 limits, would adopt fixed limits
or instead a formula.

¶34            I also agree with the majority that § 16-941(B) is ambiguous,
Op. ¶ 13, contrary to the parties’ conflicting contentions that the “plain
meaning” or “explicit” language of § 16-941(B) supports their respective
positions. The “plain meaning” rule guides our analysis when statutory
language is “subject to only one reasonable meaning.” See Arizona Early
Childhood Dev. & Health Bd. v. Brewer, 221 Ariz. 467, 470 ¶ 10, 212 P.3d 805,
808 (2009). When, as is true here, a statute may reasonably be interpreted
more than one way, determining its meaning is not advanced by
assertions that one plausible interpretation must be right because it
reflects the “plain meaning.”

¶35           The majority also correctly concludes that our analysis is not
aided by the “specific reference” canon discussed in Nelson Machinery Co.
v. Yavapai County, 108 Ariz. 8, 9, 491 P.2d 1132, 1133 (1971). Although
Nelson Machinery noted that statutes that specifically reference another are
presumed to refer to the other statute in its then-existing version, the
Court did not apply the canon in that case, id., and it is unclear whether
we have otherwise endorsed it. Rather than distinguish Nelson Machinery,
Op. ¶ 27, I would disclaim the specific reference canon entirely.

                VICE CHIEF JUSTICE BALES, Dissenting

¶36             “Our primary objective in construing statutes adopted by
initiative is to give effect to the intent of the electorate.” See Brewer, 221
Ariz. at 470 ¶ 10, 212 P.3d at 808 (quoting State v. Gomez, 212 Ariz. 55, 57 ¶
11, 127 P.3d 873, 875 (2006)); Op. ¶ 11. Accordingly, rather than relying on
any canon, we should look to the intent of the voters to determine if § 16-
941(B) refers to § 16-905 in its 1998 version or instead as it may later be
amended. Cf. United States v. United Mine Workers of Am., 330 U.S. 258, 314
(1947) (“[A] canon, like other generalities about statutory construction, is
not a rule of law. Whatever persuasiveness it may have in construing a
particular statute derives from the subject matter and the terms of the
enactment in its total environment.”) (Frankfurter, J., concurring).

¶37           The voters clearly stated their intent in enacting the CCEA:
to reduce the influence of large campaign contributions. The CCEA noted
that the then-existing system of private financing “[a]llow[ed] Arizona
elected officials to accept large campaign contributions from private
interests over which they have governmental jurisdiction,” permitted
disproportionate influence by “a small number of wealthy special
interests,” and “[drove] up the cost of running for state office.” A.R.S.
§ 16-940(B).

¶38           Also relevant is the context in which the voters approved the
CCEA. After the voters had first approved contribution limits and other
campaign finance regulations in 1986, and the so-called “AzScam” scandal
in 1991 had revealed troubling instances of misconduct and outright
corruption in connection with campaign contributions, the Legislature
increased the contribution limits three times between 1993 and 1997. 1993
Ariz. Sess. Laws, ch. 226, § 4 (1st Reg. Sess.); 1994 Ariz. Sess. Laws, ch. 379,
§ 2 (2d Reg. Sess.); 1997 Ariz. Sess. Laws, ch. 201, § 6 (1st Reg. Sess.).

¶39           Against this backdrop, the most plausible conclusion is that
the voters in 1998 intended to reduce the limits to eighty percent of the
amounts the Legislature had just set the previous year. It strains belief,
and contradicts the voters’ stated purpose, to instead conclude that the
voters intended to tie the contribution limits prospectively to eighty
percent of whatever amounts the legislature might choose to set in § 16-
905. Such a formula would make the reduction in § 16-941(B) illusory,
since the legislature could raise the limits to any desired amount merely
by increasing the limits in § 16-905 to 125 percent of that amount.

                     V. BRAIN (BENNETT)
               VICE CHIEF JUSTICE BALES, Dissenting

¶40           The majority points out that neither the 1998 ballot nor the
publicity pamphlet explicitly informed voters that the CCEA would set
fixed limits. Op. ¶ 21. But neither did these materials tell voters that the
CCEA would create merely a formula tied to future increases. Given that
the CCEA is ambiguous and the ballot measure materials are inconclusive
on the specific issue, we should be guided by the voters’ more general
purposes in enacting the CCEA. See Hayes v. Cont'l Ins. Co., 178 Ariz. 264,
270, 872 P.2d 668, 674 (1994).

¶41           The majority justifies its conclusion by squinting to find
clues of the voters’ intent from textual arguments that are at best
inconclusive. For example, the majority states that if the voters had
wanted to set specific limits, rather than adopt a formula, they could have
specified the limits in § 16-941(B) rather than referencing § 16-905. Op.
¶ 15. The majority notes that the CCEA provides specific amounts in
other sections. Op. ¶ 16. This argument, however, ignores the fact that
the amounts stated in the other sections did not have counterparts in pre-
existing law, and thus there was no reasonable possibility of incorporation
by reference. Section 16-941(B), in contrast, could refer to a twenty
percent reduction in the limits already specified in § 16-905. This made
clear that the CCEA was reducing pre-existing limits and avoided the
need to specify dollar amounts for each of the ten limits taken from §16-
905. See A.R.S. § 16-905 (1997), amended by 2007 Ariz. Sess. Laws, ch. 277
(1st Reg. Sess.) (listing ten limits with specific dollar amounts). Similarly,
there is no inconsistency between the voters referencing the inflation-
adjustment provision in § 16-905 while separately providing an inflation-
adjustment provision for other amounts fixed by the CCEA. Because § 16-
905 had a pre-existing adjustment mechanism, it could be referenced in
the CCEA and there was no need to create a new one.

¶42          In response, the majority states that even if the drafters of
the CCEA might have chosen to refer to § 16-905 for ease of reference, “it
defies common sense to conclude that voters, who had no role in the
drafting process, were similarly motivated.” Op. ¶ 16. But the voters
never collectively “draft” ballot measures. Common sense supports
construing a measure’s ambiguous language to further the general
purposes the voters expressly approved. It is unconvincing to say the
voters must have been “motivated” to adopt a formula because they
approved language in § 16-941(B) referencing § 16-905. This begs the

                                     17
       ARIZONA CITIZENS CLEAN ELECTIONS COMMISSION
                     V. BRAIN (BENNETT)
               VICE CHIEF JUSTICE BALES, Dissenting

question whether the voters intended the reference to adopt the existing
limits or instead a formula.

¶43           The majority also posits two purposes the voters might have
intended a formula to serve, but neither withstands scrutiny. First, the
majority observes that if § 16-941(B) adopts a formula, the CCEA would
allow the legislature to ensure the “gap” between the CCEA-adjusted
limits for state candidates and the limits for local candidates does not
exceed twenty percent. Op. ¶¶ 18–19. The CCEA did result in lower
contribution limits for legislative candidates than for local candidates.
(For example, as a result of the CCEA, the individual contribution limits
were $256, while the limit for local candidates was $320.)

¶44           The CCEA did not affect the existing contribution limits for
local candidates, and nothing in the CCEA or its history suggests that the
voters intended to preserve a “twenty-percent gap” between state and
local limits. Since the CCEA did not affect local limits at all, it is unclear
why the voters would have had any expectations regarding them. By
attributing to the voters a purpose nowhere stated, the majority interprets
the CCEA to achieve a result (increasing the role of large campaign
contributions) that the voters expressly sought to avoid.

¶45           The majority also contends that the voters chose a formula in
order to “increas[e] the chances that § 16-941(B) would remain viable” as
an incentive for candidates to participate in the public funding system,
even in the face of increases to the § 16-905 limits. Op. ¶ 25. Insofar as the
voters sought to provide incentives to participate in public funding,
however, this purpose is better advanced by construing § 16-941(B) as
adopting fixed limits rather than a formula. Public funding allotments
under the CCEA are not tied to the contribution limits for non-
participating candidates, so public funding would generally become less
appealing as it becomes easier for candidates to receive large private
contributions.

¶46          The majority incorrectly states that “[a]t the time voters
passed the CCEA initiative, the now-defunct matching-funds provision
existed to ensure that public funding kept pace with private
contributions.” Op. ¶ 26. Matching funds could not exceed twice the
amount of the initial public funding, A.R.S. § 16-952(E) (1998), so a

                                     18

publicly funded candidate could not “keep pace” with a privately funded
candidate who spent more. A formula allowing dramatic increases in
contribution limits like those approved by the majority would make it
easier for privately funded candidates to outpace their publicly funded
opponents, even when matching funds existed.

¶47           Because the voters in 1998 sought to reduce the role and
influence of private contributions in political campaigns, the CCEA is
more plausibly construed as lowering the limits as they then existed under
§ 16-905 rather than tying them to increases the legislature might later
enact. Thus, I respectfully dissent.
