Opinion
BORDEN, J.
The sole issue in this reservation is whether General Statutes § 36a-1561 prohibits a bank2 [3]*3from charging a convenience fee to a nondepositor who uses that bank’s automated teller machine (ATM). We answer the reservation in the negative.
The stipulation reveals the following facts. The plaintiffs are John P. Burke, the banking commissioner of the state of Connecticut (commissioner), and the state of Connecticut. The defendants, Fleet National Bank (Fleet), First Union National Bank (First Union), and BankBoston, N.A. (BankBoston), are national banks that have established and operate ATMs in Connecticut. An ATM is defined under Connecticut law as “a stationary or mobile unattended device, including a satellite device but excluding a point of sale terminal, at which banking transactions, including, but not limited to, deposits, withdrawals, advances, payments or transfers, may be conducted . . . .” General Statutes § 36a-2 (3). A point of sale terminal is defined as “a device located in a commercial establishment at which sales transactions can be charged directly to the buyer’s deposit, loan or credit account, but at which deposit transactions cannot be conducted . . . .” General Statutes § 36a-2 (45).
In addition to servicing its own depositors, an establishing bank3 may, through its participation in an ATM network, process transactions for nondepositors who hold ATM car ds issued by other banks, also called card-issuing banks, which are members of the ATM network. [4]*4There are three types of charges associated with transactions processed through an ATM network. First, an interchange fee is a fee that an establishing bank receives from another member bank in the network, whose depositor uses the establishing bank’s ATM. Second, the ATM depositor fee“is a fee charged by a bank to its own depositor for use of an ATM operated by either the depositor’s bank or another bank. Third, the ATM nondepositor fee, also commonly referred to as a convenience fee or surcharge, is a fee charged by an establishing bank to a nondepositor who uses that bank’s ATM. At issue in this appeal is the permissibility under state law of imposing the ATM nondepositor fee.4
The issue raised by this appeal originated with an interpretive letter issued by the commissioner in September, 1995, which declared that § 36a-156 implicitly prohibits ATM nondepositor fees. In January, 1997, Fleet brought an action against the commissioner and the state banking department in the United States District Court for the District of Connecticut, claiming that § 36a-156 does not prohibit ATM nondepositor fees, or, in the alternative, that federal law preempts any such prohibition. The District Court granted summary judgment for Fleet, holding that § 36a-156 does not prohibit ATM nondepositor fees. Fleet Bank, National Assn. v. Burke, 23 F. Sup. 2d 196, 203 (D. Conn. 1998). On appeal from that judgment, however, the United States Court of Appeals for the Second Circuit held that the District Court lacked subject matter jurisdiction. Fleet Bank, National Assn. v. Burke, 160 F.3d 883, 893 (2d Cir. 1998), cert. denied, 527 U.S. 1004, 119 S. Ct. 2340, 144 L. Ed. 2d 237 (1999). Accordingly, the Second Circuit vacated the judgment and directed that the action be dismissed. Id.
[5]*5Fleet and First Union immediately brought separate actions against the commissioner, which since have been consolidated in the United States District Court for the District of Connecticut, claiming various violations of 42 U.S.C. § 1983. See First Union National Bank v. Burke, United States District Court, Docket No. 3:98CV2171 (JBA) (D. Conn. April 7, 1999). Thereafter, the commissioner, invoking General Statutes §§ 36a-505 [6]*6and 36a-52,6 issued atemporary ex parte order and notice [7]*7of hearing, claiming that Fleet, First Union and Bank-Boston were in violation of § 36a-156 by imposing ATM nondepositor fees, and ordering those banks to cease and desist from that practice. The banks requested a hearing in accordance with § 36a-50. The hearing was postponed while the District Court considered requests for a preliminary injunction filed by the banks and the United States Office of the Comptroller of the Currency (Comptroller), during which time the banks agreed not to impose ATM nondepositor fees. The commissioner did not proceed with the hearing with respect to Bank-Boston.
After receiving the cease and desist order, Fleet and First Union filed applications for an injunction in the Superior Court pursuant to § 36a-52 (d) to set aside or suspend the enforcement of the order. After a hearing, the trial court, Teller, J., denied the banks’ applications for an injunction. Fleet National Bank v. Burke, 45 Conn. Sup. 566, 580, 727 A.2d 823 (1998).
Shortly thereafter, the Comptroller intervened in the consolidated action seeking to restrain the administrative hearing by virtue of a temporary restraining order and a preliminary injunction against the commissioner [8]*8and the banking department. The District Court granted the Comptroller’s request for a preliminary injunction, and prohibited the commissioner from continuing with the pending administrative proceedings against Fleet and First Union until final disposition of the merits of the Comptroller’s complaint.7 First Union National Bank v. Burke, supra, United States District Court, Docket No. 3:98CV2171 (JBA). That decision expressly did not preclude either the Comptroller from initiating its own administrative proceeding pursuant to § 36a-156, or the commissioner from seeking enforcement through the state courts. Id.
The commissioner then brought this action in the Superior Court, pursuant to his authority under § 36a-50 (b), to enforce his interpretation of § 36a-156, as described in his September, 1995 interpretive letter. At the request of all parties, and to expedite the resolution of this litigation, the trial court, Hon. Jerry Wagner, judge trial referee, approved the joint stipulation of facts and reserved the following question for the advice of the Appellate Court pursuant to General Statutes § 52-2358 and Practice Book § 73-1:9 “Does General Stat[9]*9utes § 36a-156 prohibit a bank which has established an automated teller machine from charging a fee to a nondepositor who uses the bank’s machine?” We transferred the reservation from the Appellate Court to this court pursuant to General Statutes § 51-199 (c) and Practice Book § 65-2. We answer the reservation in the negative.
We first address the applicable standard of review. “Ordinarily, this court affords deference to the construction of a statute applied by the administrative [10]*10agency empowered by law to carry out the statute’s purposes. . . . [A]n agency’s factual and discretionary determinations are to be accorded considerable weight by the courts. ” (Internal quotation marks omitted.) Connecticut Assn. of Not-for-Profit Providers for the Aging v. Dept. of Social Services, 244 Conn. 378, 389, 709 A.2d 1116 (1998); Connecticut Light & Power Co. v. Texas-Ohio Power, Inc., 243 Conn. 635, 642, 708 A.2d 202 (1998); Dept. of Administrative Services v. Employees’ Review Board, 226 Conn. 670, 678, 628 A.2d 957 (1993). “Cases that present pure questions of law, however, invoke a broader standard of review than is ordinarily involved in deciding whether, in light of the evidence, the agency has acted unreasonably, arbitrarily, illegally or in abuse of its discretion.” (Internal quotation marks omitted.) Connecticut Assn. of Not-for-Profit Providers for the Aging v. Dept. of Social Services, supra, 389; Connecticut Light & Power Co. v. Texas-Ohio Power, Inc., supra, 642; Dept. of Administrative Services v. Employees’ Review Board, supra, 678. “Furthermore, when a state agency’s determination of a question of law has not previously been subject to judicial scrutiny . . . the agency is not entitled to special deference.” (Internal quotation marks omitted.) Connecticut Assn. of Not-for-Profit Providers for the Aging v. Dept. of Social Services, supra, 389; Connecticut Light & Power Co. v. Texas-Ohio Power, Inc., supra, 642; Dept. of Administrative Services v. Employees’ Review Board, supra, 678-79. Whether § 36a-156 implicitly prohibits ATM nondepositor fees had not been subject to judicial consideration prior to the commissioner’s interpretive letter,10 and is purely a question of law concerning the [11]*11interpretation of the relevant statutory provisions. We therefore give no special deference to the commissioner’s interpretation of § 36a-156.
The question reserved for this court presents a question of statutory interpretation. “The process of statutory interpretation involves a reasoned search for the intention of the legislature. Frillici v. Westport, 231 Conn. 418, 431, 650 A.2d 557 (1994). In other words, we seek to determine, in a reasoned manner, the meaning of the statutory language as applied to the facts of this case, including the question of whether the language actually does apply. In seeking to determine that meaning, we look to the words of the statute itself, to the legislative history and circumstances surrounding its enactment, to the legislative policy it was designed to implement, and to its relationship to existing legislation and common law principles governing the same general subject matter. . . . Id.; Carpenteri-Waddington, Inc. v. Commissioner of Revenue Services, 231 Conn. 355, 362, 650 A.2d 147 (1994); United Illuminating Co. v. Groppo, 220 Conn. 749, 755-56, 601 A.2d 1005 (1992).” (Internal quotation marks omitted.) Bortner v. Woobridge, 250 Conn. 241, 258-59, 736 A.2d 104 (1999).
The plaintiffs argue that § 36a-156 prohibits the imposition of ATM nondepositor fees because it imposes only an interchange fee and thus implicitly disallows the imposition of any other fees. The plaintiffs expressly contend, however, that § 36a-156 does not prohibit depositor fees. The defendants argue that § 36a-156 does not prohibit such fees because the statute does not govern the fees that may be charged to customers, whether depositors or nondepositors. We agree with the defendants.
We conclude that § 36a-156 governs the establishment of ATMs by banks, the conditions under which other banks must be afforded access to those ATMs, [12]*12and the financial terms, as between the establishing bank and the other banks, of that access. We further conclude that § 36a-156 does not, either expressly or by implication, govern the imposition of customer fees, whether depositor fees or nondepositor fees.
We start with the statutory language at issue. Section 36a-156 provides: “(a) One or more banks, Connecticut credit unions or federal credit unions which have established a satellite device or point of sale terminal shall make the satellite device or point of sale terminal available on a nondiscriminatory basis for use by any other bank, Connecticut credit union or federal credit union, upon payment by each such other bank or credit union of a reasonably proportionate share of all acquisition, installation and operating costs of the satellite device or point of sale terminal. The satellite device or point of sale terminal shall identify with equal prominence all of the banks, credit unions or network systems which use the satellite device or point of sale terminal, (b) Any bank, Connecticut credit union or federal credit union which has established an automated teller machine which is not a satellite device may, in its discretion, permit any other bank, Connecticut credit union or federal credit union to use such automated teller machine, provided, (1) if such permission is granted to any other bank, Connecticut credit union or federal credit union, the automated teller machine is made available on a nondiscriminatory basis for use by any other bank, Connecticut credit union or federal credit union, upon payment of reasonably proportionate costs as described under subsection (a) of this section, and (2) such use is otherwise in accordance with subsection (a) of this section.” (Emphasis added.)
We first recognize the differences among the three types of banking devices covered by the statute — specifically, satellite device, point of sale terminal and automated teller machine which is not a satellite device [13]*13(hereinafter nonsatellite device). A satellite device is defined as “an automated teller machine which is not part of an office of the bank, Connecticut credit union or federal credit union which has established such machine . . . .” General Statutes § 36a-2 (51). In common parlance, a satellite device is an ATM machine located not at a bank, but elsewhere, such as in a supermarket or an office building lobby. A point of sale terminal is defined as “a device located in a commercial establishment at which sales transactions can be charged directly to the buyer’s deposit, loan or credit account, but at which deposit transactions cannot be conducted . . . .” General Statutes § 36a-2 (45). A point of sale terminal is not an ATM machine, but rather a device by which a customer may make a purchase at a commercial establishment. Point of sale terminals are commonly located in supermarket checkout lines and pharmacies. Finally, a nonsatellite device is an ATM machine located in a branch of the establishing bank— e.g., a Fleet ATM machine located at a Fleet branch.
Although the title of a statute is not determinative of its meaning, we often have looked to a statute’s title as some evidence of that meaning. See, e.g., State v. Dash, 242 Conn. 143, 147, 698 A.2d 297 (1997); Anderson v. Ludgin, 175 Conn. 545, 554, 400 A.2d 712 (1978). The title of § 36a-156, “Availability of machines, devices and terminals for use by other banks and credit unions,” is indicative of the statute’s limited purpose. It suggests that the statute governs the manner in which the establishing bank shall make the banking devices available to other banks. It makes no mention of how the establishing bank shall treat customers, whether depositors or nondepositors.
Although the language of the statute refers to the three types of banking devices described previously, the statute treats satellite devices and point of sale terminals differently from nonsatellite devices. Subsec[14]*14tion (a) of the statute applies only to satellite devices and point of sale terminals. Subsection (a) of § 36a-156 provides in relevant part: “One or more banks . . . which have established a satellite device or point of sale terminal shall make the satellite device or point of sale terminal available on a nondiscriminatory basis . . . .’’(Emphasis added.) This provision mandates that banks that have established satellite devices or point of sale terminals make the device available on a nondiscriminatory basis for use by any other bank, so long as the other bank pays the interchange fee. To illustrate, if bank A establishes a satellite device or a point of sale terminal, it must grant access to banks B, C and D, so long as these other banks pay the interchange fee. There is no discretion given to the establishing bank under subsection (a) of § 36a-156 as to the availability of these devices to other banks.
In contrast to subsection (a), however, subsection (b) of § 36a-156 applies only to nonsatellite devices, and gives banks discretion to make the device available to any other bank. Subsection (b) of § 36a-156 provides in relevant part: “Any bank . . . which has established an automated teller machine which is not a satellite device may, in its discretion, permit any other bank ... to use such automated teller machine ... on a nondiscriminatory basis . . ..” (Emphasis added.) To illustrate, if bank A establishes and operates a nonsatel-lite device, it is not required under § 36a-156 to provide any other bank with access to its nonsatellite device. If, however, bank A chooses to grant such access to bank B, it must then provide the same access to banks C and D, so long as banks B, C and D pay the interchange fee, as required by § 36a-156. Stated another way, the statute prohibits bank A from allying with bank B in order to form an exclusive ATM network, thereby excluding banks C and D. The contrast between subsections (a) and (b) of § 36a-156 is significant because it [15]*15highlights the statute’s purpose in governing bank-to-bank relationships.
Although the establishing bank has discretion in one type of situation and not in the other, the common denominator is that access, once granted by the establishing bank to another bank, either voluntarily with regard to nonsatellite devices or by statutory mandate with regard to satellite devices and point of sale terminals, must be provided on a nondiscriminatory basis. The statute expressly envisions a type of ATM network in which an establishing bank makes available on a nondiscriminatory basis its ATM machines and point of sale terminals, “upon payment by each such other bank or credit union of a reasonably proportionate share of all acquisition, installation and operating costs . . . .” General Statutes § 36a-156 (a). The statutory language regarding the interchange fee provides the condition to the nondiscrimination requirement: availability of the banking devices must be made on a nondiscriminatory basis, so long as the card-issuing bank pays the interchange fee. This statutory language evinces a legislative intent to facilitate shared ATM networks and to prohibit exclusionary ATM networks.
Furthermore, the last sentence of subsection (a) of § 36a-156 supports the construction that the legislature intended to prevent banking configurations that would favor, or discriminate against, certain card-issuing banks. That provision provides: “The satellite device or point of sale terminal shall identify with equal prominence all of the banks, credit unions or network systems which use the satellite device or point of sale terminal.” (Emphasis added.) General Statutes § 36a-156 (a). The statute, therefore, prohibits the establishing bank from creating a network that favors one member bank over another.
To summarize, we are presented with § 36a-156 entitled: “Availability of machines, devices and terminals [16]*16for use by other banks and credit unions.” It recognizes three different types of banking devices — satellite devices, point of sale terminals and nonsatellite devices. It regulates two of these types of devices differently from the third type. In all situations where nondiscriminatory access is required, however, the statute permits the estabhshing bank to charge “a reasonably proportionate share of all acquisition, installation and operating costs . . . .” General Statutes § 36a-156 (a). Conspicuously absent from this statute is any language referring to fees or charges that may or may not be directly imposed on customers — either depositors or nondepositors of the establishing bank.
We next look to the statute’s legislative history. There is nothing in the legislative history of Substitute Senate Bill No. 401, the bill eventually enacted as Public Acts 1975, No. 373, and codified as General Statutes §§ 36a-156 through 36a-159, to support the argument that § 36a-156 implicitly prohibits ATM nondepositor fees. To the contrary, the legislative history supports our conclusion that the enactment of this statutory scheme provided the framework in which state banks could establish ATMs and point of sale terminals. The legislative history also supports our construction that the discrimination addressed by the statute solely concerns the establishing bank’s discrimination or selectivity among other banks.
The legislative history demonstrates that § 36a-156 was the state legislature’s response to the grant of authority by the Federal Home Loan Bank Board and the Comptroller in December, 1974, to federal savings and loan associations and national banks to establish satellite devices and point of sale terminals. 18 H.R. Proc., Pt. 10, 1975 Sess., p. 4868; Conn. Joint Standing Committee Hearings, Banks, 1975 Sess., pp. 211, 214, 224, 237, 240, 244, 257. These national financial institutions could establish such devices without regard to [17]*17state bank branching laws because, according to the Comptroller, these devices were not “branches.” Conn. Joint Standing Committee Hearings, supra, pp. 211, 214. In 1973, however, the state attorney general had opined that the commissioner lacked the authority to permit state banks to operate these devices. Id., pp. 212, 240. Without any action taken by the state legislature, therefore, state financial institutions would not have been able to offer the same services as their national counterparts.
Legislative committee hearings may be relevant to the meaning of statutes because they often demonstrate the problem or issue that the legislature sought to address by the statute. Ferrigno v. Cromwell Development Associates, 244 Conn. 189, 197, 708 A.2d 1371 (1998); Mahoney v. Lensink, 213 Conn. 548, 559-60, 569 A.2d 518 (1990). The hearings regarding the legislation eventually codified as §§ 36a-156 through 36a-159 indicate that the banking industry had two primary concerns: first, that state chartered banks did not have authority similar to federally chartered banks to establish satellite devices and point of sale terminals; and second, that smaller financial institutions would be excluded from ATM networks in the absence of mandatory sharing.
During the committee hearings, members of the banking industry acknowledged the disadvantage that state banks would encounter without the same ability as national institutions to establish these banking devices. For example, Elliott C. Miller, then senior vice president of Society for Savings, stated before the joint standing committee on banks: “[This bill] empowers state banking institutions to establish and use satellite devices and point-of-sale terminals.” Conn. Joint Standing Committee Hearings, supra, p. 210. Miller, representing a state chartered financial institution, recognized the need for such legislation, pointing out that “federal reg[18]*18ulatory agencies — the Federal Home Loan Bank Board and the [Comptroller] — have already started to authorize the use of these facilities by the federally chartered institutions under their respective jurisdictions.” Id., p. 211. Miller further stated: “[W]e, the state chartered financial institutions, are asking, through this legislation, to be allowed to adapt to change along with our federally chartered sister institutions.” Id., p. 213. Similarly, Stephen J. Sweeney, then assistant treasurer of the Naugatuck Savings Bank, made the following comments during the committee hearings: “[A]s you know there is presently legislation which would allow national banks to recognize satellite stations. In Nauga-tuck where there are two national banks, the competitive disadvantage for the Naugatuck Savings Bank would be a dimension the results of which would be disastrous for us.” Id., pp. 224-25.
Not only do the committee hearings demonstrate the need to give state banks the authority to establish these banking devices, the hearings also demonstrate the purpose to prevent exclusionary ATM networks. For example, during the committee hearings, Stanley Spilecki, then chairman of the special committee on electronic funds transfer systems for the Savings Banks’ Association of Connecticut, made the following statement: “Without shared satellite facilities only a few very large institutions would be able to set up a network of devices necessary to dominate the rapidly approaching era of electronic funds transfer systems. This is true now because only the large institutions have the research staff to find the best location for satellite facilities, the resources to purchase or control these locations, and the resources to put in place the expensive equipment and support them in a manner most likely for success.” Id., p. 216. This statement recognizes that, because smaller banks may not have the resources necessary to establish and to operate ATMs and point of sale [19]*19terminals, they might otherwise be precluded from such ATM usage. Without a provision such as § 36a-156 providing for nondiscriminatory participation, larger financial institutions could ally with one another, form an ATM network, and deny participation to smaller institutions that could not provide ATM and point of sale services to their depositors on their own.
The floor debate also indicates that the legislature sought to ensure that state chartered banks would not be precluded from competing in this area. During one Senate debate, when Senator Richard C. Bozzuto was asked when outlying communities could expect ATM machines, he responded: “As of yet, the federal [government has] not allowed National Banks to avail themselves of this until July of 1975, so this Bill will coordinate with that privilege and I would say immediately thereafter . . . .” 18 S. Proc., Pt. 5, 1975 Sess., p. 2241. During the legislative debate in the House of Representatives, Representative Raymond C. Lyddy stated: “[The point of sale terminal] is a revolutionary device, but Federal Agencies have already authorized this and have begun using them under Federally chartered institutions that are under their jurisdiction. This [bill] allows our financial institutions in this State, to use these same facilities and thereby enable our banks to meet the competition that will be generated by the National banking institutions.” 18 H.R. Proc., supra, p. 4868.
We are also mindful that the legislature and the banking industry, at the time of the enactment of § 36a-156, regarded this technology and the idea of mandatory shared networks as new and highly experimental. See, e.g., 18 S. Proc., supra, p. 2240, remarks of Senator Bozzuto (“the Bill will provide for a new technology within the Banking Industry”); 18 H.R. Proc., supra, p. 4868, remarks of Representative Lyddy (“[Substitute Senate Bill No. 401] represents a response to new tech[20]*20nology in the banking industry”); Conn. Joint Standing Committee Hearings, supra, p. 249, remarks of Charles Lord, president of Hartford National Bank and Trust Company (“[mandatory sharing] is highly experimental”); id., pp. 210-12, remarks of Elliott C. Miller (“[s]at-ellite devices represent a significant technological development as part of the banking industry’s efforts to furnish traditional banking services to customers in more convenient ways . . . this whole area will be largely experimental for awhile”). Such a backdrop cannot support a finding that the legislature regarded this legislation as comprehensive, as it related to ATM usage, nor that it foresaw the proliferation of such devices and fees, as the plaintiffs suggest. Rather, this historical context supports our conclusion that the legislature did not intend § 36a-156 to be an exhaustive list of fees that banks permissibly could impose in any ATM context.11
[21]*21Finally, in interpreting the meaning of § 36a-156, we look to the relationship between the statute at issue and existing legislation regarding the same general subject matter. In 1975, the General Assembly enacted several statutes regarding the establishment and usage of ATMs and point of sale terminals. See General Statutes §§ 36a-155 through 36a-159. Nowhere in the language of any of these statutes does the legislature address fees of any kind that may be imposed on customers — depositors or nondepositors. In fact, the only mention of customers in this legislation appeal’s in § 36a-155 (b), which confers, inter alia, power to the commissioner to adopt regulations regarding the safety of customers using these banking facilities.
We also look to the Deposit Account Contract Act; General Statutes §§ 36a-315 through 36a-323; for its treatment of ATM fees. First, that act is a disclosure statute that places several restrictions on the manner in which fees, or deposit account charges,12 may be [22]*22imposed on depositors. For example, General Statutes § 36a-317 (b) provides in relevant part: “No financial institution shall impose or attempt to impose any deposit account charge that has not been disclosed to the depositor pursuant to section 36a-318 or 36a-320, as applicable, or is in an amount greater than the amount disclosed to the depositor pursuant to section 36a-318 or 36a-320, as applicable. ...” Similarly, General Statutes § 36a-320 (a)13 specifies other notice requirements to which a bank must adhere in order to impose deposit account charges on depositors. Nowhere in the act, however, does the legislature expressly grant or deny authority to the banks to charge ATM depositor fees. That act, therefore, assumes that the authority to impose fees does exist.
Additionally, General Statutes § 36a-250 supports our conclusion that § 36a-156 does not address customer fees in any way, either directly, or by negative implication. Pursuant to § 36a-250, which provides an extensive list of the express powers of state banks, banks may: act as depositories of court and trust funds; General Statutes § 36a-250 (3); act as transfer agents or registrars of stocks and bonds; General Statutes § 36a-250 [23]*23(9); establish charitable funds; General Statutes § 36a-250 (17); and provide home banking services to customers. General Statutes § 36a-250 (23). Although this statute, which provides a thirty-nine item list of banks’ express powers, does not expressly provide for the imposition of ATM depositor fees, the plaintiffs concede that the banks have such power. It would be anomalous to conclude, in light of the Deposit Account Contract Act and § 36a-250, that § 36a-156 prohibits ATM nonde-positor fees.
The plaintiffs argue that the reference in § 36a-156 to the nondiscriminatory imposition of the interchange fee means that the legislature implicitly meant to prohibit the imposition of the nondepositor fees. Thus, the plaintiffs’ argument rests on the axiom “expressio unius est exclusio alterius,” translated from the Latin to mean, “the expression of one thing is the exclusion of another.” Although the so-called canons of statutory construction may at times serve as useful tools in deciphering legislative meaning, to rely on any one of them as a compelling factor in the interpretive process is problematic, because as Professor Karl Llewellyn persuasively has demonstrated, “there are two opposing canons on almost every point.” K. Llewellyn, “Remarks on the Theory of Appellate Decision and the Rules or Canons About How Statutes Are to Be Construed,” 3 Vand. L. Rev. 395, 401 (1950). The so-called “canons” are not that, at least in the sense that any one of them reliably can be determined to apply or not to apply in any given case. They are, instead, merely guides drawn from experience, to be employed or not to be employed carefully and judiciously, depending on the circumstances. See F. Frankfurter, “Some Reflections on the Reading of Statutes,” 47 Colum. L. Rev. 527, 544-45 (1947); see also United Illuminating Co. v. New Haven, 240 Conn. 422, 455, 692 A.2d 742 (1997). “To permit them to displace the conclusions that careful interpretation [24]*24yields . . . would be a disservice to the legislative process, as well as to the judicial exercise of interpreting legislative language based upon the premise that the legislature intends to enact reasonable public policies.” United Illuminating Co. v. New Haven, supra, 455.
Although we have at times interpreted certain statutory provisions as demonstrating a legislative intent to exclude, by implication, other possible referents; see, e.g., State v. Kish, 186 Conn. 757, 766, 443 A.2d 1274 (1982) (statutory itemization demonstrates legislative intent to exclude unenumerated items); we decline to do so where there is no language, legislative history or statutory purpose suggesting that we reach such a result. See Williams Ford, Inc. v. Hartford Courant Co., 232 Conn. 559, 584-85, 657 A.2d 212 (1995); Fahy v. Fahy, 227 Conn. 505, 513, 630 A.2d 1328 (1993).
Furthermore, the plaintiffs’ reliance on the negative implication purportedly created by the statute’s reference to the interchange fee is inherently inconsistent. They specifically concede that the statute does not prohibit depositor fees. It is difficult to understand how the purported negative implication could prohibit one type of customer fee but not another.
The plaintiffs also misconstrue the phrase, “on a nondiscriminatory basis,” which is contained in § 36a-156, as it relates to the availability of ATMs. They argue that the discrimination that is prohibited by § 36a-156 occurs when the establishing bank charges an ATM nondepositor fee. The discrimination that the statute proscribes, however, is discriminatory conduct by the estabhshing bank with respect to other banks. The statute does not mention, either explicitly or implicitly, differentiation of fees among various categories of customers.
The plaintiffs also argue that the Deposit Account Contract Act supports their position that nondepositor fees statutorily are prohibited. They contend that, [25]*25although § 36a-156 permits an interchange fee, thereby implicitly prohibiting all other ATM fees, the Deposit Account Contract Act provides an implicit exception to the otherwise general prohibition of § 36a-156 against ATM fees being charged to customers, and permits banks to charge only ATM depositor fees, i.e., fees charged to the bank’s own depositors. Thus, the plaintiffs argue that that act implicitly confers authority on the banks to impose ATM depositor fees. For this proposition they rely on the definitional section of the Deposit Account Contract Act, specifically, § 36a-316 (6), which defines deposit account charge.14 As explained previously, however, that act does not grant any authority to banks to charge depositor fees; it merely assumes that such authority exists, to be employed or not as a business decision by the banks.
The plaintiffs also attempt to import into § 36a-156 a consumer protection or antitrust focus that neither the statute’s language, history nor background plausibly will bear. To that end, the plaintiffs refer to the defendants’ imposition of ATM nondepositor fees as “the latest salvo in the current fee war being waged by large banks against the public’s access to its funds and against smaller banks.” The plaintiffs contend, in essence, that the legislature foresaw undue market dominance by large banks as a result of ATMs. Their reading ignores the purposes that the legislature did have in enacting this legislation: to allow state financial institutions to participate in this new technology; and to prevent exclusionary ATM networks. There is nothing in the statute’s language, history or background that supports the plaintiffs’ contentions.
Those contentions, moreover, are inconsistent with the undisputed facts that, when this legislation was enacted in 1975, the entire area of the use of ATMs was [26]*26experimental and untested in the marketplace, and that the legislature regarded it as such. No one, including our legislature, could have foreseen at that time what the economic and competitive effects of ATMs would be. Indeed, as the defendants point out, the marketplace already has begun to respond to the purported dominance by large banks.15 If there is to be state regulation of ATM customer fees, that is a policy matter for the determination by the legislature based on current economic and other relevant data. It simply is not, as the plaintiffs suggest, a question that was implicitly resolved in 1975.
We answer the reserved question in the negative. The case is remanded for further proceedings according to law.
No costs will be taxed in this court to any party.
