TJOFLAT, Circuit Judge:

In this case, Dr. Joe L. Reed, a member of the Board of Trustees for Alabama State University, seeks a declaratory judgment that an age limit in Ala. Code § 16-50-20(a) prohibiting a board member from serving beyond September 30 following his seventieth birthday does not apply to him for two reasons: first, § 16-50-20(b) creates an exception shielding him from the age limit; second, and alternatively, the age limit is facially unconstitutional because it denies persons over seventy years of age the equal protection of the laws guaranteed them by the Fourteenth Amendment to the United States Constitution. The district court rejected both reasons and denied relief. Reed now appeals. We affirm.

Before turning to the reasons for our decision, it is helpful to describe the statute at issue and to explain the proceedings in the district court.

A.

Alabama Code § 16-50-20 governs the composition of the Board of Trustees for Alabama State University ("ASU"). Prior to 1986, the trustees served staggered six-year terms, with one-third of the terms expiring every two years. The governor had the power to appoint trustees and could reappoint each trustee to serve one additional six-year term. See 1975 Ala. Laws 1581 (creating § 16-50-20); 1983 Ala. Laws 878 (amending § 16-50-20 in ways not material to this case). In 1986, Alabama's legislature amended this statute to increase the number of trustees on the board, to increase the trustee terms from six years to twelve years, and to stagger the terms to expire every three years instead of every two. 1986 Ala. Laws 1051. The governor retained his appointment power. Id. To implement the new staggering scheme, the governor had the authority to divide the trustees — those on the old board plus those appointed to fill the newly created seats — into four even groups serving initial three, six, nine, and twelve-year terms. These initial trustees (the new board) were eligible to serve two full twelve-year terms in addition to their initially designated terms (presumably because most of their initial terms were for less than twelve years to create the staggering scheme). Trustees succeeding the initial trustees (each of whom would be appointed for twelve years) could be reappointed to serve a second twelve-year term. Id.

In addition to requiring staggered terms, § 16-50-20(a) imposes other limits and requirements on the trustees. For example, one trustee must be drawn from each congressional district in Alabama (two are drawn from the district in which ASU is located), and four members are drawn from the state at large; the members drawn from the state at large must all reside in different districts; trustees representing congressional districts automatically vacate their seats if they move out of their district; a majority of the trustees must be ASU alumni; trustees may not be paid except to cover the expenses incurred in the course of their duties; trustees may not also be employees, students, or trustees of other public colleges; state officials with power over ASU's budget may not be trustees (with the exception of the governor, who is the ex officio president of the board); and state employees may not serve as trustees. The statute also sets out the appointment and confirmation process for the trustees.

Germane to this case, the amended statute retains an age limit, which reads, "No member shall serve past September 30 following his seventieth birthday." Ala. Code § 16-50-20(a). The 1986 amendment also added a new subsection (b) to the statute, which reads in its entirety, as codified, "No trustee who is serving on the said board on April 30, 1986, shall lose his or her seat because of this section; provided, however, the Governor may re-designate the period of the term of these members so as to conform to the provisions of subsection (a)." Id. § 16-50-20(b) (emphasis added). For brevity, we refer to the first clause of subsection (b) (up to the semicolon) as the "exemption clause," and to the second clause as the "redesignation clause." These aspects of the statute — the subsection (a) age limit and subsection (b) — are at issue in this appeal.

B.

Dr. Joe Reed was a member of the ASU board when § 16-50-20 was amended in 1986. On April 30, 1986, the governor designated Reed's term as a twelve-year term to implement the statute's term-staggering scheme. On February 1, 1999, Reed was reappointed to a second twelve-year term. Reed turned seventy on September 13, 2008. According to the age limit in § 16-50-20(a), Reed would not have been able to serve on the board beyond September 30, 2008, even though his second twelve-year term would have lasted longer.

Anticipating this problem, Reed, William Clark, an ASU alumnus, and Thomas Figures, an ASU trustee, brought this action against Bob Riley, the governor of Alabama, and Elton Dean, the chair of the ASU board (collectively, the "Governor") in their official capacities in the Circuit Court of Montgomery County, Alabama, on February 2, 2007. Their complaint challenged the age limit in § 16-50-20(a), as it related to the 1986 trustees, on the ground that § 16-50-20(b) nullifies that limit. They challenged § 16-50-20(a) on the additional ground that it is barred by the Equal Protection Clause of the Fourteenth Amendment in two ways: first, the section discriminates on account of age without a rational basis; second, it treats trustees at ASU differently than trustees at other public universities who are not subject to age limits.

The Governor removed the suit to the U.S. District Court for the Middle District of Alabama because it presented a federal question. The Governor then moved the district court to dismiss the case on the following grounds: (1) Clark's interest as an ASU alumnus was insufficient to provide him with standing to sue; (2) Figures lacked standing because his term would expire prior to his seventieth birthday; (3) Reed's claim was moot because his term had been redesignated under § 16-50-20(b) so as to expire on September 30, 2008, just as it would under the age limit provision; and (4) the age limit in § 16-50-20(a) did not deny persons over seventy the equal protection of the law under the Fourteenth Amendment. The district court granted the motion as to Clark and Figures, deferred ruling on the question of whether Reed's claim was moot, and denied the motion as to the equal protection claim. The court then instructed Reed to amend his complaint to respond to the mootness issue.

Reed amended his complaint and, at the same time, moved the court for summary judgment. The Governor countered with a motion to dismiss the complaint for failure to state a claim for relief. In an order entered on March 31, 2008, the district court found that the term "section" in subsection (b) created ambiguities and inconsistencies in the statute because if read literally, it would nullify nearly all of the limits imposed on trustees by subsection (a), giving the 1986 trustees in effect lifetime appointments. The court then turned to the legislative history of § 16-50-20, which indicated that the legislature had actually used the word "act," not "section," in subsection (b) in the 1986 amendment to § 16-50-20. The court also observed that the legislature passed the 1986 amendment specifically to implement the revised staggering scheme, which would be defeated by reading subsection (b) literally. Accordingly, the district court held that both clauses of subsection (b) should be construed narrowly so as to only apply when the 1986 amendments first took effect.

The district court also held that the age limit in subsection (a) did not deny the 1986 trustees or persons over seventy the equal protection of the laws in violation of the Fourteenth Amendment. The court identified multiple rational bases for treating trustees over the age of seventy differently. The court also found that, contrary to Reed's assertions, two other Alabama universities' boards had age limits, and thus that ASU trustees were not being treated differently than their counterparts at other Alabama public universities.

Accordingly, the district court denied Reed's motion for summary judgment, granted the Governor's motion to dismiss and entered judgment pursuant to its March 31 order. Reed now appeals the court's judgment, presenting two issues: first, whether § 16-50-20(b) exempts trustees who were on the board when the 1986 amendments took effect from the age limit imposed by § 16-50-20(a); and second, whether the age limit denies such trustees and others over seventy the equal protection of the laws, either because there is no rational basis for discriminating against such persons over seventy in general, or because there is no rational basis for discriminating against trustees over seventy at ASU but not at other similar Alabama universities.

"We review de novo the district court's grant of a motion to dismiss under 12(b)(6) for failure to state a claim, accepting the allegations in the complaint as true and construing them in the light most favorable to the plaintiff." Hill v. White, 321 F.3d 1334, 1335 (11th Cir. 2003) (per curiam). This case involves the interpretation of a state statute. "In rendering a decision based on state substantive law, a federal court must `decide the case the way it appears the state's highest court would.'" Ernie Haire Ford, Inc. v. Ford Motor Co., 260 F.3d 1285, 1290 (11th Cir. 2001) (quoting Royal Ins. Co. of Am. v. Whitaker Contracting Corp., 242 F.3d 1035, 1040 (11th Cir. 2001)).

We address at length only the statutory interpretation question. We dispose of Reed's equal protection challenge in the margin.

III.

Reed argues that the plain language of the statute calls for what the district court termed a "broad/narrow" interpretation of Ala. Code § 16-50-20(b): the exemption language in the first clause should be read broadly to exempt Reed (and any other 1986 trustees) from the age limit in § 16-50-20(a), but the redesignation provision in the second clause should be interpreted narrowly as a one-time grant of power so that the governor could redesignate trustees' terms only in 1986 to establish the statutorily created staggering scheme. The Governor asserts that the language of the original 1986 amendment dictates the "narrow/narrow" reading adopted by the district court: both provisions of subsection (b) were meant to apply only when the 1986 amendments took effect. After our own review of the statute, we are convinced that the district court's so-called "narrow/narrow" interpretation of the statute is the correct one.

Although the Alabama Supreme Court has considered § 16-50-20(a) on multiple occasions, those decisions addressed primarily the appointment and confirmation process for trustees. No opinion of record discusses subsection (b) or the age limit in subsection (a). Therefore, we must attempt to step into the shoes of the Alabama Supreme Court and interpret § 16-50-20 as that court would.

In Alabama, "[t]he fundamental rule of construction is to ascertain and effectuate the intent of the Legislature as expressed in the statute." League of Women Voters v. Renfro, 292 Ala. 128, 290 So.2d 167, 169 (1974). "`[T]he court has a duty to ascertain and effectuate legislative intent expressed in the statute, which may be gleaned from the language used, the reason and necessity for the act, and the purpose sought to be obtained.'" Blue Cross Blue Shield of Ala., Inc. v. Nielsen, 714 So.2d 293, 296 (Ala. 1998) (quoting Ex parte Holladay, 466 So.2d 956, 960 (Ala. 1985)). Determining legislative intent begins with the plain language of the statute:

Words used in a statute must be given their natural, plain, ordinary, and commonly understood meaning, and where plain language is used a court is bound to interpret that language to mean exactly what it says. If the language of the statute is unambiguous, then there is no room for judicial construction and the clearly expressed intent of the legislature must be given effect.

IMED Corp. v. Sys. Eng'g Assocs. Corp., 602 So.2d 344, 346 (Ala. 1992). But plain language will not be followed to the point of absurdity:

It has been called a golden rule of statutory interpretation that unreasonableness of the result produced by one among alternative possible interpretations of a statute is reason for rejecting that interpretation in favor of another which would produce a reasonable result. . . . It is fundamental . . . that departure from the literal construction of a statute is justified when such a construction would produce an absurd and unjust result and would clearly be inconsistent with the purposes and policies of the act in question. A construction resulting in absurd consequences as well as unreasonableness will be avoided.

Ex parte Meeks, 682 So.2d 423, 428 (Ala. 1996) (quoting Norman J. Singer, Sutherland Statutory Construction § 45.11, at 61 (5th ed. 1993)). With these principles of statutory interpretation in mind, we turn to the text of § 16-50-20.

Section 16-50-20(b) reads, in full, "No trustee who is serving on the said board on April 30, 1986, shall lose his or her seat because of this section; provided, however, the Governor may re-designate the period of the term of these members so as to conform to the provisions of subsection (a)." At first blush, the exemption clause plainly says that a 1986 trustee cannot lose his seat on the board because of the age limit in subsection (a). But the implications of reading the clause plainly extend beyond its effect on the age limit. Subsection (a) has many other provisions that would also divest trustees of their seats. For example, trustees representing congressional districts must vacate their seats if they move out of their districts, but under a broad reading of subsection (b), 1986 trustees would be exempt from this provision. They would also be exempt from the conflict of interest requirements, the two-term limit, and even the twelve-year term limit, effectively giving them lifetime appointments to the ASU board and preventing their removal for holding conflicting positions in the state government or other universities. Indeed, Reed's plain-language reading of the exemption clause would undermine nearly the entire ASU board structure established in subsection (a), including the staggering scheme — an absurd result. Surely the legislature would not have intended to revamp significantly ASU's board structure while simultaneously not only exempting every sitting board member from the new requirements, but also giving them in effect lifetime appointments (which were never permissible under the previous board scheme).

If the exemption clause were to be read broadly based on plain language, then the redesignation clause would likewise be read broadly because there is no indication that the two clauses in subsection (b), which are separated by a mere semicolon, should be interpreted differently than one another. The redesignation clause clearly lets the governor redesignate the 1986 trustees' terms to conform with subsection (a). The plain text of the clause contains no limiting temporal language, so at first glance the clause would seem to grant the governor authority to redesignate terms at any time, not just when the 1986 act was initially passed. Conceivably, then, the legislature may have been creating a default rule that exempts 1986 trustees from the requirements in subsection (a) while giving the governor the power to override the exemptions on a case-by-case basis.

But importantly, the governor may only redesignate terms; the redesignation clause does not permit the governor to force a 1986 trustee to vacate his seat. The governor could thus force compliance with the twelve-year term limits and the age limit, but he would still be powerless to enforce the provisions in subsection (a) that do not relate to term length — namely the requirements (already discussed) that one trustee represent each congressional district, the prohibitions on trustees holding certain other positions to prevent conflicts of interest, and the limits on the number of terms a trustee may serve. Moreover, interpreting the redesignation clause this way would upset the carefully crafted staggering scheme and the twelve-year terms because the governor could redesignate terms at will. It is inconceivable that the Alabama legislature would subject its newly created board scheme to undermining in such an arbitrary manner. Because a literal interpretation of subsection (b) would lead to absurd consequences, we turn for guidance, as did the district court, to the legislative history behind § 16-50-20.

The Alabama legislature created § 16-50-20 in 1975, 1975 Ala. Acts. 1581, and amended it in 1983, 1983 Ala. Acts, 878, and 1986, 1986 Ala. Acts 1051. As written in the 1986 Amendment, subsection (b) stated, "No trustee who is serving on the said board on the effective date of this act shall lose his or her seat because of this act; provided, however the governor may re-designate the period of the term of these members so as to conform to the provisions of Section 16-50-20(a)." 1986 Ala. Acts at 1052-53 (emphasis added).

The difference between the word "act" used in the amendment and the word "section" that appears in the codified version is significant and demonstrates how the Alabama legislature actually intended subsection (b) to operate. "Section" refers to a portion of the code, whereas "act" refers to the legislative action creating the statute. A "section" operates indefinitely, but an "act" is a transient process, operating only to create the statute. Although the word "act" can be changed to a word like "section" during the codification process, see Ala. Code § 29-7-8(a) ("The Code Commissioner. . . . may. . . . [s]ubstitute the proper hierarchy unit for the terms `this act,' `the preceding section,' and the like."), the two are not always synonymous, and context is important. As explained supra, for the legislature to have meant that "act" be changed to "section" during the codification process, it necessarily would have to have intended to undermine the very changes that it was making to the ASU board. Given this context, it is much more likely that the legislature intended that "act" refer to the actual passage of the legislation, thus declaring its intention not to strip any 1986 trustees of their seats in the process of passing the amendment to restructure the ASU board. The title of the amendment confirms this reading, describing the amendment as an act

[t]o amend Section 16-50-20, Code of Alabama 1975, as amended, so as to enlarge the membership of the Alabama State University Board of Trustees, prescribe the qualifications, balance, terms of office and appointment; to provide that no current member may be removed as a result of this bill, but allows the governor to redesignate the respective terms of office to conform to the staggered terms.

1986 Ala. Acts at 1051-52 (emphasis added). This original legislative language makes clear that the legislature intended for subsection (b) to apply only when the governor initially implemented the new staggering scheme created by the 1986 amendment.

Viewed in light of the actual enacting legislation, subsection (b)'s operation becomes clear. The Alabama legislature amended § 16-50-20 to change the structure of and the rules governing the ASU board. One of those changes altered the staggering of the trustees' terms. Because there was already a board of trustees governing ASU in 1986, someone had to sort the existing board members into the newly created staggered terms. The legislature tasked the governor with this reorganization by adding the redesignation clause, but at the same time it included the exemption clause to ensure that no then-sitting trustees lost their seats in the process. Hence, the legislature included subsection (b) not to give the 1986 trustees in effect life tenures, but rather to provide for an orderly reshuffling of the board. Accordingly, "the letter of the statute yield[s] to the true meaning and intent of the lawmakers." League of Women Voters, 290 So.2d at 169. Subsection (b) — both the exemption clause and the redesignation clause — applied only to the initial reshuffling of the board that occurred when the 1986 amendment was passed, as clearly indicated by the language of the 1986 amendment.

The district court thus correctly applied its "narrow/narrow" interpretation to subsection (b) and correctly applied the age limit in subsection (a) to Reed.

IV.

For the foregoing reasons, the judgment of the district court dismissing Reed's complaint for failure to state a claim for relief is

AFFIRMED.
