This litigation represents the continuation of an effort by appellee American University (“AU”) to stop appellant American University in Dubai (“AUD”) from holding a license from the District of Columbia Educational Licensure Commission (“the Commission”) while AUD continues to have the word “American” in its name. The underpinning for the litigation is D.C.Code § 29-618 (Supp.2009), which generally prohibits an educational institution that is organized under District of Columbia law or that “shall undertake to do business in the District of Columbia or to confer degrees or certificates therein” from using “as its title, in whole or in part the words United States, federal, American, national, or civil service, or any other words which might reasonably imply an official connection with the government of the United States.... f1 For reasons that *178we shall explain, we conclude that AU’s challenge to AUD’s (former) District licen-sure is moot. We affirm, however, the trial court’s order insofar as it directs the Commission to revoke the license of AUD’s agent. Judge Thompson dissents from the latter conclusion.
I. Legal and Factual Background
The District of Columbia laws governing the licensure of post-secondary educational institutions are found in Title 29, Chapter 6 and Title 38, Chapter 13 of the D.C.Code. See D.C.Code §§ 29-615 to -619 (2001 & Supp.2009) and 38-1301 to -1313 (2001 & Supp.2009). They provide that no person or entity may undertake to confer any degree or operate a post-secondary educational institution in the District of Columbia without first obtaining a license from the Commission.2 See D.C.Code §§ 29-615, 38-1309(a) (Supp.2009). Commission licensure of an educational institution “shall be contingent upon said educational institution’s compliance with all rules, regulations and criteria promulgated by the Commission, as well as compliance with all other applicable D.C. laws and regulations.” D.C.Code § 38-1302(12) (Supp.2009).3 One such applicable law is D.C.Code § 29-618, enacted by Congress in 1929 as part of legislation known as the Diploma Mill Act.4
D.C.Code § 38-1310(a) describes several “exclu[sions] from the coverage of this chapter [ie., D.C.Code §§ 38-1301 to - 1313],” including an exclusion for any “educational institution that is organized or chartered outside of the District of Columbia and does not operate in the District....” D.C.Code § 38-1310(a)(6) (2001). Thus, an educational institution that is not organized under District law and that does not operate in the District is exempt from licensure by the Commission, “except that any agent of an institution who operates in the District shall not be exempt, and the Commission may apply the standards of this chapter to the institution in determining whether to license an agent.” Id. D.C.Code § 38-1302(1) defines “agent” as “any person owning any interest in, employed by, or representing for remuneration, an educational institution, whether such institution is located within or outside the District, and who solicits or offers to enroll in the District students or enrollees for such institution, or who holds himself or herself out to *179residents of the District ... as representing an educational institution for any such purpose.” D.C.Code § 38-1302(1).
Appellee AUD is a private, for-profit, accredited degree-granting institution with its campus in Dubai, United Arab Emirates. AUD has no facilities and provides no educational instruction in the District, but does provide information about its programs in Dubai and enrolls students for its Dubai campus through an agent, Michael Goldstein, who, for remuneration, acts on AUD’s behalf from an office on New Hampshire Avenue, N.W.5 In past years, the Commission licensed AUD directly. However, by early 2008, the Commission began to apply an interpretation that an educational institution without a physical presence in the District could not be licensed by the Commission. In addition, in August 2008, the Council of the District of Columbia enacted the Education Licensure Commission Amendment Act of 2008 (“the 2008 Amendment Act”),6 legislation that made revisions to Chapter 13 of Title 38 that affect whether an educational institution may “operate” — and thus whether it is eligible for licensure — in the District. As modified by the 2008 Amendment Act, D.C.Code § 38-1309 provides that an educational institution may not “operate” in the District — and thus, it may not obtain a Commission license, which constitutes “approval to operate,” see D.C.Code § 38-1302(12) — unless it maintains in the District a “facility” from or through which “education is offered or given, or educational credentials are offered or granted.” D.C.Code §§ 38-1309, -1302(11). The 2008 Amendment Act also added to section 38-1302 a definition of the term “facility” that specifies that the term means “a physical structure located in the District, including suitable housing, classrooms, laboratories, and library resources, as required by the nature of the program or the student body.” D.C.Code § 38-1302(14).
AUD does not maintain a “facility” in the District within the meaning of section 38-1302(14). Since February 28, 2008, Mr. Goldstein has been licensed as AUD’s agent,7 and, effective the same date, AUD withdrew its application for renewal of its Commission license.
II. Procedural Background
This appeal follows our decision in American Univ. in Dubai, a case that arose out of a 2003 suit in which AU complained that the Commission had renewed AUD’s degree-granting license despite what AU alleged was AUD’s violation of the prohibition set out in D.C.Code § 29-618, by having “American” in its name. AU sought a judgment “prohibiting AUD from using ‘American’ in its ti*180tle[,]” a declaration that it was unlawful for the Commission to license AUD so long as the school remained in violation of section 29-618, and an order requiring the Commission to revoke AUD’s license. 930 A.2d at 204. The trial court entered summary judgment in favor of AU and ordered the Commission to revoke AUD’s license within 30 days unless, prior to that deadline, AUD changed its name to comport with section 29-618. After learning of the court’s order, and instead of changing its name, AUD filed a motion to intervene, which the trial court denied. Id. at 204-OS. In compliance with the trial court’s order, the Commission revoked AUD’s license. AUD sought review by this court, and we vacated the trial court’s order and the Commission order revoking AUD’s license. We did so on the ground that AUD was an indispensable party and that AU should not have been allowed to proceed with its suit without naming AUD as a party. Id. at 210. We directed the trial court to dismiss AU’s complaint. Id.
In December 2007, AU filed a new complaint, naming both the Commission and AUD as defendants, seeking virtually the same relief as in the earlier litigation except that AU did not request a declaration that AUD is precluded from using the word “American” in its title.8 In December 2008, the trial court entered summary judgment in favor of AU. The court reasoned that AUD was in violation of section 29-618 because the “statute prohibits the use of ... the word ‘American’ in the title of an institution[, and] AUD is a for-profit institution with the word ‘American’ in its title.” The court ordered the Commission to revoke both AUD’s license and the agent’s license of Mr. Goldstein (who, having obtained the license months after AU filed its complaint, was not a party to the suit), within 30 days of the order. This appeal followed.
III. Analysis
We address the issues on appeal as follows. First, we conclude that AU’s challenge to AUD’s licensure is moot. Second, we hold — contrary to the District’s argument — that AU’s ability to obtain review of the Commission’s licensure of AUD and Goldstein does not hinge on whether the Diploma Mill Act creates a private right of action. Third, we reject AUD’s argument that the trial court should have dismissed AU’s complaint under Super. Ct. Civ. R. 19 for failure to join necessary parties. Fourth, and finally, we hold that the Commission abused its discretion by granting a license to AUD’s agent.
A. AU’s challenge to AUD’s licensure.
Appellants argue that, even before the trial court issued its order, the dispute about AUD’s licensure by the Commission was rendered moot by the 2008 Amendment Act, the legislation that clarified that an educational institution may be licensed to “operate” in the District only if it maintains a “facility” here, i.e., “a physical structure ... including suitable housing, classrooms, laboratories, and library resources, as required by the nature of the program or the student body.” D.C.Code §§ 38-1302(11), (14) and 38-1309(a)(2). Both the District and AUD take the position that the 2008 Amendment Act rendered AUD ineligible for licensing, since AUD “has no physical presence in the District of Columbia ... [ie.,] it has no facilities, no employees, leases no space and provides no educational services [within] the District of Columbia”; both acknowledge that AUD’s license has expired; and AUD affirms that it is “no longer even *181qualified for a Degree Granting License as of August 16, 2008,” the effective date of the 2008 Amendment Act. We accept the District’s interpretation (which also is AUD’s interpretation) that AUD is ineligible for licensure, inasmuch as the interpretation is a reasonable construction of the statutory language, contravenes nothing in the (scant) legislative history,9 and represents the position of the Commission, the agency charged with implementing the relevant statutory provisions. See Nova Univ. v. Educational Inst. Licensure Comm’n, 483 A.2d 1172, 1190-91 (D.C. 1984) (applying, in evaluating Commission’s position, principle that “when an agency’s decision is based on an ‘interpretation of the statute and regulations it administers, [that interpretation] will be sustained unless shown to be unreasonable or in contravention of the language or legislative history of the statute.’ ”) (citation omitted). Although AU appears to be correct that the Commission rather abruptly changed its interpretation even prior to enactment of the 2008 Amendment Act, and even though an agency’s changed interpretation of a statute may command less deference than a longstanding interpretation,10 the amendments to Chapter 13 effected through the 2008 Amendment Act amply explain and justify the Commission’s changed interpretation. Those amendments effectively nullified AUD’s license. We conclude therefore that the 2008 legislation deprived the trial court of the ability to grant, and that this court has no power to sustain, the initial relief that AU sought — an order that the Commission revoke AUD’s license.11 Accordingly, we agree with appellants that the issue of AUD’s licensure is moot. See Settlemire v. District of Columbia Office of Emp.' Appeals, 898 A.2d 902, 905 (D.C.2006) (explaining that an event that renders relief unnecessary renders a matter moot); Thorn v. Walker, 912 A.2d 1192, 1195 (D.C.2006) (“[I]f ... the appellate court can provide no effective relief, the ease is moot.”).12 Consequently, we vacate that *182portion of the court’s order requiring the Commission to revoke AUD’s license. See U.S. Bancorp Mortg. Co. v. Bonner Mall P’ship, 513 U.S. 18, 21, 115 S.Ct. 386, 130 L.Ed.2d 233 (1994) (explaining that if a judgment has become moot while awaiting review, an appellate court may not consider its merits, but should reverse or vacate the judgment below and remand with a direction to dismiss.)
B. The private right of action argument.
The District’s principal argument is that AU cannot obtain review of the Commission’s licensing decisions because the “Diploma Mill Act does not create a private right of action to enforce D.C.Code § 29-618.” This argument fails for two reasons.
As a threshold matter, the District’s “private right of action” argument is squarely foreclosed by our holding nearly fifteen years ago that “[j]udicial reviewa-bility of agency action does not depend on the creation of a private right of action in the statute sought to be enforced.” District of Columbia v. Sierra Club, 670 A.2d 354, 359 (D.C.1996) (citing Japan Whaling Ass’n v. American Cetacean Soc’y, 478 U.S. 221, 230-31 n. 4, 106 S.Ct. 2860, 92 L.Ed.2d 166 (1986)). As then-Judge Breyer explained in a case involving the federal Administrative Procedures Act, “it is difficult to understand why a court would ever hold that Congress, in enacting a statute that creates federal obligations, has implicitly created a private right of action against the federal government, for there is hardly ever any need for Congress to do so. That is because federal action is nearly always reviewable for conformity with statutory obligations without any such ‘private right of action.’ ” NAACP v. Secretary of Hous. & Urban Dev., 817 F.2d 149, 152 (1st Cir.1987) (quoted in Sierra Club, 670 A.2d at 359). What is true of suits against federal agencies for alleged violations of federal duties is true of suits against District agencies for alleged violations of duties imposed by District law. Thus, in Sierra Club, we held that Sierra Club, an environmental organization, had a right to judicial review of its allegation that the District suspended its recycling program in violation of District law; following NAACP (and other cases), we emphatically rejected the District’s contention that a private right of action analysis had any bearing on the question whether the District’s actions were reviewable by a private party that was aggrieved by those actions. Sierra Club, 670 A.2d at 356, 357-61. Similarly in this case, AU’s complaint involves a routine challenge to agency action. Thus, AU’s ability to obtain review of the Commission’s actions does not depend on the existence of a private right of action.
The District’s claim that § 29-618 — the Diploma Mill Act provision that bars educational institutions from using the word “American” in their titles — does not create privately enforceable rights also overlooks the fact that AU is not suing anybody for violating § 29-618. Rather, AU is suing the Commission for violating the ELC Act by granting a license to AUD and to Gold-stein. True, AU’s theory for why the Commission abused its discretion under the ELC Act is that the Commission could not issue a license to AUD so long as the latter was in violation of § 29-618. But AU does not allege (how could it?) that the Commission itself violated § 29-618. Therefore, the District is battling a straw-man when it claims that § 29-618 does not create a private right of action.
In its reply brief, the District makes an argument different from its “private right of action” claim; it relies on the principle that agency decisions not to prosecute or not to enforce are presumptively unreview*183able. E.g., Heckler v. Chaney, 470 U.S. 821, 881, 105 S.Ct. 1649, 84 L.Ed.2d 714 (1985); Tucci v. District of Columbia, 956 A.2d 684, 690 (D.C.2008); J.C. & Assocs. v. District of Columbia Bd. of Appeals & Review, 778 A.2d 296, 309 (D.C.2001); Sierra Club, 670 A.2d at 860. We have no quarrel with this proposition as a general matter. Indeed, we have held that “ ‘the determination whether and when to institute enforcement proceedings against a specific individual is a core executive responsibility which may reasonably be viewed as having been committed to agency discretion so as to preclude substantive judicial review.’” Tucci, 956 A.2d at 690 (quoting Sierra Club, 670 A.2d at 360) (brackets omitted). Tucci concerned two District residents — the Tuccis — who were frustrated by, among other things, their neighbors’ alleged failure properly to dispose of garbage. Id. at 687-88. In response to this grievance, the Tuccis sued the District seeking a court order requiring “more robust enforcement” of the Litter Control Administration Act against their neighbors. Id. at 690. We affirmed the trial court’s grant of summary judgment in favor of the District on this claim, holding that the enforcement action that the Tuccis sought was “a core executive function committed to the discretion” of the District, which in turn meant that judicial review of the Tuccis’ suit was “precluded.” Id.
The presumption that enforcement decisions are not reviewable is inapplicable in this case for the simple reason that, unlike the plaintiffs in Tucci, AU is challenging actions that the Commission has taken—to wit, the Commission’s grants of licenses to AUD and Goldstein. See Chaney, 470 U.S. at 831, 105 S.Ct. 1649; J.C. & Assocs., 778 A.2d at 308 (“if the Mayor does choose to take action, his decision may be contested one way or another”). The unreviewa-bility presumption of course may resurface later in the struggle between AU and the Commission. For instance, if after our decision in this case the Commission revokes AUD’s license but fails to seek other enforcement against AUD, the Commission likely will rely on the presumption in order to resist AU’s attempt to force its hand further. (And because “a private citizen lacks a judicially cognizable interest in the prosecution or nonprosecution of another,” Linda R.S. v. Richard D., 410 U.S. 614, 619, 93 S.Ct. 1146, 35 L.Ed.2d 536 (1973), AU also will not be able to force the U.S. Attorney’s Office to prosecute AUD.) At this juncture, however, the presumption of unreviewability does not bar review of the Commission’s actions.
In the end, as far as reviewability is concerned, this case is no different from the host of challenges to District agency actions that we hear each year. Consider, for example, challenges to decisions by District regulators to permit new construction, sign off on zoning variances, or the like. See, e.g., Cathedral Park Condo. Comm. v. District of Columbia Zoning Comm’n, 743 A.2d 1231 (D.C.2000); Downtown Cluster of Congregations v. District of Columbia Bd. of Zoning Adjustment, 675 A.2d 484 (D.C.1996); Dupont Circle Citizens Ass’n v. Barry, 455 A.2d 417, 419, 422-23 (D.C.1983); see also Brentwood, 661 A.2d 652, 653 (D.C.1995) (holding that “holders of liquor licenses in the same neighborhood” as a license recipient had standing “to assert the violation of a regulation prohibiting the issuance of a liquor license to an establishment located within 400 feet of another licensee”). We have never suggested in such cases that an aggrieved party’s right to judicial review of the agency’s decision is conditioned on the existence of a private right of action in the statutes that the agencies are alleged to have violated. In short, although our review of agency action often is deferential, *184the notion that no review at all can be had in this case “cannot be reconciled with the applicable precedents or with the sound reasons of policy that underlie them.” Sierra Club, 670 A.2d at 357.
C. The Rule 19 argument.
Although we have concluded that AU’s challenge to the Commission’s licensure of AUD is moot, AU’s challenge to the Commission’s licensure of AUD’s agent is live because the agent continues to hold that license. As we shall explain below, we hold that the Commission abused its discretion by granting a license to AUD’s agent. Before discussing the merits, however, we must address AUD’s argument that the trial court erred by failing to dismiss AU’s action for failing to name necessary parties under Super. Ct. Civ. R. 19(a).
As mentioned above, when AU first sued the Commission over its licensure of AUD, we held that AUD was an indispensable party and that AU should not have been allowed to proceed with its suit without naming AUD as a party. 930 A.2d at 210. So AU returned to the trial court and filed a new complaint in which it named AUD as a co-defendant along with the Commission. AUD says that was not enough. According to AUD, AU also was required to join as defendants seven other institutions— ranging from the American Petroleum Institute to the National Housing Corporation Learning Center — that AUD says will be affected by AU’s suit. We agree with AU that its failure to join entities other than AUD did not require the trial court to dismiss the case.
“Joinder of necessary parties is governed by Rule 19, which makes it clear that questions of compulsory joinder are to be resolved on the basis of practical considerations.” Raskauskas v. Temple Realty Co., 589 A.2d 17, 20 (D.C.1991) (quotation marks omitted). AUD relies on Rule 19(a), which says, as relevant here, that where an absent party “claims an interest relating to the subject of the action and is so situated that the disposition of the action in the person’s absence may ... as a practical matter impair or impede the person’s ability to protect that interest,” the court must join that party. Citing AUD I, AUD argues that the trial court should have dismissed AU’s action for failing to join certain institutions that, according to AUD, also stand to lose their licenses as a result of AU’s action. We are not persuaded.
The difference between AUD I and this case is straightforward. In AUD I, we held that AU should have joined AUD as a defendant because “AUD’s right to retain its license was at the center of the Superi- or Court dispute and the very reason why AU filed a complaint in the Superior Court seeking declaratory and injunctive relief.” 930 A.2d at 208. In contrast, the licenses of the seven institutions whose rights AUD now seeks to invoke were neither “at the center of the Superior Court dispute” nor “the very reason” why AU sued the Commission in Superior Court. Id. True, a holding that the Commission acted unlawfully in granting licenses to AUD and AUD’s agent could well create a “negative precedent” for a host of entities. But few cases are sui generis; litigation often produces decisions that have effects that extend beyond the parties before the court. That does not mean, however, that every case of potentially broad import requires the joinder under Rule 19 of each person and entity that stands to gain or lose from the litigation. Were the rule otherwise, every challenge to gun control regulations in the wake of District of Columbia v. Heller, — U.S. —, 128 S.Ct. 2783, 171 L.Ed.2d 637 (2008), would require the join-der of millions of gun owners, would-be *185gun purchasers, and state and local governmental bodies. That is not the law. Similarly, in this case, the potential impact of this litigation on parties not before the court did not require the joinder of those parties.
Nor are we persuaded by the District’s argument that AU was required to amend its complaint to join Goldstein. (Goldstein obtained his agent’s license after AU filed its complaint, and was not named as a defendant in AU’s action). It is notable that AUD — which certainly knows how to raise procedural objections and has the most to lose from a holding that the Commission abused its discretion in granting Goldstein an agent’s license— has not claimed that AU’s failure to join Goldstein is of any moment. And with good reason. Although Goldstein plainly has an interest in this case, his interests and AUD’s interests are for all intents and purposes identical. Therefore, and because AUD adequately represents Gold-stein’s interest, Goldstein was not a necessary party. See Ramah Navajo Sch. Bd., Inc. v. Babbitt, 87 F.3d 1838, 1351 (D.C.Cir.1996) (“If the nonparties’ interests are adequately represented by a party, the suit will not impede or impair the nonparties’ interests, and therefore the nonparties will not be considered ‘necessary.’ ”); see also Vale Props., Ltd. v. Canterbury Tales, Inc., 431 A.2d 11, 15 (D.C. 1981) (trial court may deny motion to intervene under Rule 24(a)(2) “when an existing party seeks the same ultimate objective as the [absent party]”). This is not a case where the absent party “is without a friend in [the] litigation.” Atlantis Dev. Carp., Ltd. v. United States, 379 F.2d 818, 825 (5th Cir.1967).
D. The merits.
Having cleared the procedural underbrush, we turn to the question whether the Commission abused its discretion by granting Goldstein a license. We conclude that the answer to this question is yes. But because Goldstein obtained a license solely to represent AUD, we must begin our analysis by explaining why the Commission’s grant of a license to AUD was never reconcilable with the plain language of the ELC Act and the Diploma Mill Act, even before AUD became ineligible to hold a license by virtue of not maintaining a “facility” in the District. See pages ISO-82, supra.
The ELC Act, § 38-1302(12), says that the Commission’s licensure of an educational institution “shall be contingent upon said educational institution’s compliance ... with all other applicable D.C. laws.” One of the applicable laws is § 29-618, the portion of the Diploma Mill Act that makes it a crime for “any individual or individuals, association, or incorporation outside of the District of Columbia which shall undertake to do business in the District of Columbia or to confer degrees or certificates therein” to “use as its title, in whole or in part, the word ... American.” American University in Dubai has the word “American” in its name. By soliciting clients in the District with Goldstein’s help, AUD is doing business in the District. See Black’s Law DictionaRY (8th ed. 2004) (defining “doing business” as “[t]he act of engaging in business activities; specif., the carrying out of a series of similar acts for the purpose of realizing a pecuniary benefit, or otherwise accomplishing a goal, or doing a single act with the intention of starting a series of such acts”). AUD thus is violating § 29-618, and thus is not eligible for licensure.
The arguments raised by AUD and the District as to why we should reject the straightforward reading of the statutes are not persuasive. AUD says that § 29-618 cannot mean what it says because other*186wise absurd results will ensue in cases involving certain other entities — such as, for instance, the International Graduate University. We fail to see what relevance an absurd result in a hypothetical case has in the case at hand; our task here is to apply the relevant statutes to the facts before us, not to conduct an overbreadth analysis involving hypothetical fact patterns. See Everton v. District of Columbia, 993 A.2d 595, 598 (D.C.2010) (appellant “ha[d] no standing to challenge [a] statute based on a hypothetical application to a different situation”) (citing Leiss v. United States, 364 A.2d 803, 807 (D.C. 1976)); Gorgone v. District of Columbia Bd. of Zoning Adjustment, 973 A.2d 692, 697 (D.C.2009) (petitioner could not “rely on the rights of others to avoid a result that [was] just as to him”); see also Ball v. Arthur Winn Gen. P’ship/Southern Hills Apartments, 905 A.2d 147, 152 (D.C.2006) (“courts may not rewrite statutory language merely because when pressed to an extreme application it yields a seemingly absurd result”). In this case, there is nothing absurd in the conclusion that American University in Dubai is ineligible for licensure because it violates the prohibition in § 29-618 that an education institution not have the word “American” in its name. Far from absurd, it is the only defensible reading of § 29-618, especially when coupled with the dictate in § 38-1302(12) that to obtain a license an institution must comply with all applicable D.C. laws. To the extent that AUD believes that the result makes for poor policy, its remedy lies with the legislative branch. See Ball, 905 A.2d at 152 (“Laws enacted with good intention, when put to the test, frequently, and to the surprise of the lawmaker himself, turn out to be mischievous, absurd or otherwise objectionable. But in such case the remedy lies with the law making authority, and not with the courts.”) (quotation marks omitted).
For its part, the District does not seriously contest that AUD comes within the plain text of § 29-618. The District argues, nonetheless, that we should ignore that plain language because House and Senate Reports accompanying that section allegedly show that the Act was “not designed to prevent the operation of educational institutions that are clearly not defrauding the public by using ‘deception by way of implying official connection with the United States Government.’ ” But “[b]y delving into the legislative history before establishing that the statutory language is ambiguous, [the District] violate[s] a fundamental principle of statutory interpretation. ‘In interpreting a statute, we first look to the plain meaning of its language, and if it is clear and unambiguous and will not produce an absurd result, we will look no further.’ ” Beaner v. United States, 845 A.2d 525, 534 (D.C.2004) (quoting In re D.H., 666 A.2d 462, 469 (D.C. 1995)). Thus, to the extent that the legislative history evidences a narrower intent than the plain language of the Diploma Mill Act, the statutory text must prevail. See id. Cases stating that legislative history may elucidate the meaning of statutory language of “superficial clarity,” e.g., Peoples Drug Stores, Inc. v. District of Columbia, 470 A.2d 751, 754 (D.C.1983) (en banc), are not to the contrary because there is nothing “superficial” about the clarity of § 29-618.
At the risk of gilding the lily, we add that what is plain to us today has long been plain to the District — as applied to all educational institutions, that is, except AUD. For instance, in 1984, the office of Corporation Counsel wrote that “National University” could not be licensed to do business in the District because it had the word “national” in its name; as Corporation Counsel explained, there was “no authority ... to provide exemption” on this *187point. Similarly in 1991, the Deputy Corporation Counsel advised the Commission that National Graduate University was “not eligible for licensure by the Commission due to the use of the term ‘national’ in its name.” And in July 2000, the Department of Consumer and Regulatory Affairs took the position that “American University of Asia, Inc.,” was not eligible for licen-sure because it had the word “American” in its name. Yet, notwithstanding how it interpreted § 29-618 with respect to others, the Commission for some reason approved AUD’s license in 1998. Perhaps sensing that its interpretation was absurd, twice in 2001 the ELC approved six month renewals of AUD’s license, each time subject to the requirement that AUD “change [its] name.” But AUD gamely informed the ELC before the second renewal that it was “unwilling to abandon its name” and never did. So in 2002, the ELC suddenly, and without explanation, approved a three-year renewal of AUD’s license, removing the condition that AUD change its name. Curiouser still, in 2004, following the unexplained renewal of AUD’s license despite its violation of District law, the ELC on at least two occasions informed the “American Academy of Traditional Chinese Medicine” and the “American Institute of Business Studies” of the prohibition in § 29-618 of using the word “American” in the name of their institutions. The deviation (without explanation) of the ELC’s longstanding policy against licensing institutions in violation of § 29-618 solely for the benefit of AUD is the quintessential example of arbitrary and capricious government action to which we owe no deference. See FCC v. Fox Television Stations, Inc., — U.S. -, 129 S.Ct. 1800, 1811, 173 L.Ed.2d 738 (2009) (“a reasoned explanation is needed for disregarding facts and circumstances that underlay or were engendered by the prior policy”; “to ignore such matters” in adopting a new policy “would be arbitrary or capricious”).
In short, AUD is violating § 29-618, and thus is ineligible for licensure. It follows, we conclude, that AUD cannot employ Goldstein to do indirectly what it cannot do directly. To hold otherwise would render essentially toothless and meaningless the statement in § 38-1302(12) that to obtain a license an institution must comply with “all ... applicable D.C. laws and regulations.” Nothing in the ELC Act suggests that the Council intended to permit institutions to evade § 38-1302(12) by the simple expedient of hiring agents. Of course, the Council could have written the ELC Act so as to deviate from the “ancient maxim of the law that what is forbidden to a person to do himself he cannot do by the agency of another.” Thompson v. Deal, 92 F.2d 478, 486 (D.C.Cir.1937); accord J.H. Marshall & Assocs., Inc. v. Burleson, 313 A.2d 587, 597 (D.C.1973). But nothing in the language of the ELC Act supports the conclusion that the Council intended to permit this counterintuitive result. Therefore, the “sensible construction,” School St. Assocs. Ltd. P’ship v. District of Columbia, 764 A.2d 798, 805 (D.C.2001) (quotation marks omitted), of the ELC Act is that it does not permit the Commission to grant a license to an agent of an institution that itself is not eligible for licensure.
We also reject the Commission’s decision to grant a license to Goldstein because it brings the ELC Act and the Diploma Mill Act into needless conflict with one another. Under the Commission’s reading of the two Acts, Goldstein may obtain a license under the ELC Act even though he is helping AUD violate § 29-618. But statutory interpretation is a holistic endeavor; to the extent possible, we attempt to harmonize statutes, not read them in a way that makes them run headlong into one another. See, e.g., In re *188Jacoby, 945 A.2d 1193, 1198 (D.C.2008); M.M. & G., Inc. v. Jackson, 612 A.2d 186, 192 (D.C.1992); Floyd E. Davis Mortg. Corp. v. District of Columbia, 455 A.2d 910, 912 (D.C.1983)13 In this case, the way to harmonize the ELC Act with the Diploma Mill Act is to read the former as not permitting the Commission to grant a license to an agent of an institution who is helping the institution violate the latter. Indeed, in a regulation implementing the ELC Act, the Commission itself appears to recognize this point. See DCMR 5-A8003.2 (recognizing that the Commission has some discretion in imposing requirements on educational institutions, but noting that the Commission “may not waive a requirement of any statute” in exercising that authority).
To be sure, we recognize that § 38-1310(a)(6) says that “in determining whether to license an agent” the Commission “may apply” the standards of the ELC Act governing the licensure of institutions. All that this section means, however, is that the Commission may use different standards for determining whether to license an institution as opposed to the institution’s agent. To give one logical example, the Commission requires that institutions seeking a license demonstrate that they have libraries, see DCMR 5-A8003, but does not require the same showing of agents. It does not follow, however, that just because § 38 — 1310(a)(6) permits the Commission to apply different standards to agents than institutions, the Commission also has discretion to grant a license to an agent where the institution itself is ineligible for licensure on account of being in violation of criminal law.
The dissent would read the use of “may” in § 38-1306(a) as vesting the Commission with unreviewable discretion to license agents. We respectfully disagree with this analysis. “Only upon a showing of clear and convincing evidence of a contrary legislative intent should the courts restrict access to judicial review.” Sierra Club, 670 A.2d at 358 (quotation marks omitted) (citing Abbott Labs. v. Gardner, 387 U.S. 136, 141, 87 S.Ct. 1507, 18 L.Ed.2d 681 (1967)). In our view, such clear and convincing evidence is lacking in this case. Contrary to what the dissent suggests, see Post at 197-98, the use of the word “may” is not sufficient to establish that the legislature intended to preclude review of agency action. Indeed, even cases that conclude that a statute precludes review do not rest their analysis on the use of the word “may” alone. For instance, in Webster v. Doe, 486 U.S. 592, 108 S.Ct. 2047, 100 L.Ed.2d 632 (1988), the Supreme Court held that a provision of the National Security Act of 1947, 61 Stat. 498, that provided that “the Director of Central Intelligence may, in his discretion, terminate the employment of any officer or employee of the Agency whenever he shall deem such termination necessary or advisable in the interests of the United States,” 50 U.S.C. § 403(c), precluded judicial review of a termination decision made by the Director. Webster, 486 U.S. at 594, 600, 108 S.Ct. 2047. The Court did not rely, however, simply on the fact that the statute said “may.” Rather, in concluding that the statute “fairly exude[d] deference” to the Director, the Court focused on the statute’s use of the language “deem ... advisable.” Id. The Court reasoned this language demonstrated that “[s]hort of *189permitting cross-examination of the Director concerning his views of the Nation’s security and whether the discharged employee was inimical to those interests,” there was “no basis on which a reviewing court could properly assess an agency termination decision.” Id. In addition, the Court reasoned that judicial review of the Director’s decision to terminate an employee would unduly undermine the CIA’s “effícacy[ ] and the Nation’s security,” because both “depend in large measure on the reliability and trustworthiness of the Agency’s employees.” Id.
The ELC Act does not have anything resembling the broad language analyzed in Webster. Nor does review of the Commission’s decision to issue a license to an agent whose principal is ineligible for li-censure implicate the weighty policy concerns that the Court identified in Webster as weighing against review. Therefore, we do not believe that the use of the word “may” in § 38 — 1310(a)(6) precludes review in this case.14
Nor are we persuaded by the dissent’s reliance on Chaney, 470 U.S. at 830, 105 S.Ct. 1649, for the proposition that the ELC Act does not provide “judicially manageable standards ... for judging how and when an agency should exercise its discretion,” thereby making it “impossible” for us to evaluate the Commission’s action in this case. Post at 198. The “narrow exception” that Chaney recognized, 470 U.S. at 826,105 S.Ct. 1649, does not change the outcome in this case. Although difficult cases may arise under § 38—1310(a)(6), this case is not hard. The “judicially manageable standards,” Chaney, 470 U.S. at 830, 105 S.Ct. 1649, upon which we rely in analyzing an agent’s eligibility for licen-sure under the ELC Act are found in the standards that apply to the licensure of institutions (ie., the entities that agents seek to represent), the text of the ELC and the Diploma Mill Acts, and settled principles of statutory construction.
E. The dissent’s remaining arguments.
We now turn to the arguments advanced in the dissent that we have not addressed already. The dissent begins by suggesting (though not firmly deciding) that AUD does not do business in the District through Goldstein for the purposes of the Diploma Mill Act. In reaching this conclusion, the dissent places heavy reliance on cases decided around the time that the Diploma Mill Act was enacted that interpreted the term “doing business” for the purposes of deciding whether service of process was effective. See Post at 193-94. We do not believe that those cases provide a useful point for analysis, and not simply because, as the dissent acknowledges, see id. at 194, those cases were “implicitly rejected” by International Shoe Co. v. Washington, 326 U.S. 310, 66 S.Ct. 154, 90 L.Ed. 95 (1945). The reason, rather, is that the dissent is mixing apples and oranges. In service of process and personal jurisdiction cases, “doing business” is a term of art; the question in those cases, in the words of a decision cited by the dissent, is whether the level of business that a defendant conducts in the jurisdiction where it is sued is “of such nature and character as to warrant the inference” that the defendant “by its duly authorized officers or agents is present within the state or district where service is attempted.” People’s Tobacco Co. v. American Tobacco *190Co., 246 U.S. 79, 86, 38 S.Ct. 238, 62 L.Ed. 587 (1918). Late-nineteenth and early-twentieth century cases took a narrow view of “doing business” in this context because “traditional notions of jurisdiction were based on a territorial conception that permitted actions to be brought against a defendant only in the jurisdiction in which he was found and personally served with process.” 4 Wright & Miller, Federal Practioe & Procedure § 1066, at 352 (3d ed. 2002); see also generally id., at § 1064.
The dissent does not explain why § 29-618 comes with this crabbed reading, and we find no indication in the statute that Congress intended to limit it to those entities that were doing business in the District within the meaning of cases such as People’s Tobacco. Rather, the prohibition in § 29-618 is worded broadly, and applies equally to entities that were incorporated in the District as well as to entities that were incorporated outside of the District and that “undert[ook] to do business” in the District “or to confer degrees or certificates therein.” 45 Stat. 1505, ch. 523 (Mar. 2, 1929). In view of this sweeping language, we see no reason to import service of process case law into the analysis whether an entity is undertaking to do business for the purposes of § 29-618.15
Nor are we persuaded by the dissent’s analysis of legislative history discussing the 1934 amendment to the Diploma Mill Act. See Post at 194-95. The dissent hones in on the following passage from a House Committee Report accompanying that amendment:
So far as the committee can determine, there was no intent to forbid the use of the word “American” in the titles of institutions of learning in foreign lands where the word served solely to indicate place of origin, such as the “American Academy at Rome,” the “American School of Classical Studies at Athens,” the “American University at Beirut,” and other well-known schools and colleges abroad. H. Rep. No. 1040, 73d Cong, 2 Sess. 2 (Mar. 23,1934).
If Congress thought that “American University at Beirut” was okay, the reasoning goes, see Post at 194-95, then what can be wrong with “American University in Dubai”?
The Committee Report does not cause us to alter our reading of the act. As we mentioned above, we do not find resort to legislative history in this case helpful because we think that the Diploma Mill Act is clear on its face. See Beaner, 845 A.2d at 534. Moreover, we do not find the dissent’s reading of the Committee Report persuasive because the report itself is rather tentative on the matter (“So far as the committee can determine”). Finally, assuming arguendo that the dissent is correct that the Committee Report shows that Congress though it unnecessary to amend the statute to grandfather institutions such as American University in Beirut, this congressional inaction strikes us as too shaky a foundation to rely on in this case. See United States v. Craft, 535 U.S. 274, 287, 122 S.Ct. 1414, 152 L.Ed.2d 437 (2002).
The dissent also suggests that our analysis is wrong because it would lead to “peculiar” results in cases involving not-for-profit institutions. Post at 196. AUD, *191however, is a /or-profit institution, and the dissent does not suggest that there is anything peculiar about the result we reach as to AUD. We thus do not believe that an allegedly peculiar result in a hypothetical case involving a not-for-profit institution has any relevance here. This is especially so because the Diploma Mill Act in fact treats not-for-profits differently than for-profits: § 29-618 gives the Commission discretion, under certain circumstances, to “waive the prohibition” of that section for not-for-profits, but does not authorize the Commission to make such a waiver in respect to for-profits.
IV. Conclusion
The trial court’s order is vacated insofar as it required the Commission to revoke AUD’s license, and is affirmed insofar as it required the Commission to revoke Gold-stein’s license.
So ordered.
. As we noted in our opinion in American Univ. in Dubai v. District of Columbia Educ. Licensure Comm’n, AU “was created by a special act of Congress and is the only University specifically exempted from D.C.Code § 29-618 (2001) and authorized to use the *178name 'American' in its title.” 930 A.2d 200, 202 n. 3 (D.C.2007).
. The Commission was established by the Education Licensure Commission Act of 1976 (“the ELC Act”), D.C. Law 1-104, Apr. 6, 1977 (now codified at D.C.Code §§ 38-1301 to -1313), to "license postsecondary educational institutions ... and their agents,” and to “ensure authenticity and legitimacy of the educational institutions....” D.C.Code § 38-1303 (Supp.2009).
. See also DCMR 5-A8003.1 (2009) ("The Commission shall license degree granting institutions and institutions that give instruction that results in credit toward a degree, and that the Commission determines are in compliance with the requirements of law and this chapter.").
.Act of Mar. 2, 1929, Pub.L. No. 70-950, § 586e, f, 45 Stat. 1505 (now codified as amended at D.C.Code §§ 29-614 to -619). Under D.C.Code § 29-619 (2001), originally enacted as part of the same legislation, an educational institution that undertakes to do business in the District while using in its title any of the words prohibited by section 29-618 may be subject to criminal and civil penalties. See id. (providing that "[a]ny person or persons who shall ... violate the provisions of § 29-618 shall be deemed guilty of a misdemeanor, and upon conviction thereof in the Superior Court of the District of Columbia shall be punished by a fine of not more than $2,000, or imprisonment for not more than 2 years, or both" and that "[cjivil fines, penalties, and fees may be imposed as alternative sanctions....”).
. Mr. Goldstein reported to the Commission in 2008 that none of AUD’s 2,858 students enrolled as of the Fall of 2007 were District residents.
. D.C. Law 17-219, §§ 4009-10, Aug. 16, 2008.
. This is notwithstanding the fact that the Commission’s regulations governing the licen-sure of agents of educational institutions, see DCMR 5-A8000 to 5-A8099, 5-A8100 to 5-A8199 (2009) include provisions that address the licensure of agents for non-degree-conferring institutions, but contain none that address licensure of agents for degree-granting institutions. Compare DCMR 5-A8001.1 ("This chapter shall apply to all educational institutions which offer instruction that results in credit toward a degree, which are required to be licensed....”) with DCMR 5-A8101.1 ("This chapter shall apply to all private, postsecondary non-degree schools, and their agents [.]”) (emphasis added).
AUD represents that ”[o]n April 30, 2009, at a public meeting, the [Commission] considered, and unanimously granted, Mr. Gold-stein’s Application to Renew the Agent’s License of Michael B. Goldstein for the period ending April 30, 2010.”
. The record indicates that AU also pursued relief through a suit against AUD brought under the federal Lanham Act, 15 U.S.C. § 1125.
. See Committee of the Whole Report on Bill 17-678 (May 13, 2008); Committee on Government Operations Report on Bill 7-86 (November 9, 1988); Committee on Education and Libraries Comments on Bill 7-253 (June 14, 1988); Committee on Government Operations Report on Bill 7-253 (May 12, 1988); and S.Rep. No. 611, 70th Cong., 1st Sess. 2 (1928).
. See Brentwood Liquors, Inc. v. District of Columbia Alcoholic Beverage Control Bd., 661 A.2d 652, 656 (D.C. 1995) ("while an agency may change over time the interpretation it gives to a controlling statutory term, an agency changing its course is obligated to supply a reasoned analysis for the change") (quotation marks and citation omitted); Public Serv. Comm’n v. Wilson, 389 Md. 27, 882 A.2d 849, 867 (2005) (considerable deference "is ordinarily only shown to an agency's longstanding interpretation” of the statute it is charged with administering). For a recent debate on the issue, see the majority and dissent in PCC v. Fox Television Stations, Inc., - U.S. -, 129 S.Ct. 1800, 1811, 173 L.Ed.2d 738 (2009); id. at 1830-31 (Breyer, J., dissenting).
. The issue that AU raises as to AUD’s eligibility for licensure could arise again if, for example, AUD were to establish classrooms and begin teaching courses in the District pursuant to a Commission license. However, we decline to issue an advisory opinion that looks to that possibility (which no one has suggested is on the horizon). Cf. Cropp v. Williams, 841 A.2d 328, 330 (D.C.2004) (per curiam) (rejecting argument that this court should issue an advisory opinion to "forestall[] hypothetical future clashes between” the parties).
. The trial court rejected AUD’s and the District's mootness arguments on the ground that "[t]here [was] no indication in the record that the [Commission] took any action regarding AUD’s license,” reasoning that the issue was not moot because "AUD’s license remains in effect.” But it is well-established that a matter may be rendered moot by legislation, see United States v. Alaska S.S. Co., 253 U.S. 113, 116, 40 S.Ct. 448, 64 L.Ed. 808 (1920) ("The subsequent legislation .... renders the case moot.”), and this is such a case.
. We understand the dissent to agree on this principle, though not its application in this case. See Post at 197 (stating that "we must construe actions by an earlier and later legislature on the same subject 'as though the different legislatures enacted them together,' reconciling them if possible”) (quoting United States Parole Comm'n v. Noble, 693 A.2d 1084, 1087 (D.C. 1997)).
. The dissent cites In re J.D.C., 594 A.2d 70 (D.C.1991), for the proposition that the statute’s use of the word "may” dispositively shows that the Council intended to preclude review. But J.D.C. had nothing to do with reviewability of administrative action. Instead, J.D.C. concerned a trial court's denial of a motion to exclude members of the media from a factfinding hearing in a juvenile murder case. Id. at 74.
. Incidentally, we are far less certain than the dissent appears to be that a court in 1929 would have held that AUD was not doing business in the District for the purposes of service of process. See International Harvester Co. v. Kentucky, 234 U.S. 579, 34 S.Ct. 944, 58 L.Ed. 1479 (1914) (defendant was “doing business” in Kentucky for purposes of service of process when, inter alia, defendant was involved in a "continuous course of business in the solicitation of orders” within Kentucky and employed an agent with authority to receive "payment in money, checks, or drafts” in Kentucky).
