YOUNG, J.
This case concerns judicial review of an administrative agency’s interpretation of a statute. This Court has not always been precise in articulating the proper standard for reviewing such interpretations. However, in accordance with longstanding Michigan precedent and basic separation of powers principles, we hold and reaffirm that an agency’s interpretation of a statute is entitled to “respectful consideration,” but courts may not abdicate their judicial responsibility to interpret statutes by giving unfettered deference to an agency’s interpretation. Courts must respect legislative decisions and interpret statutes according to their plain language. An agency’s interpretation, to the extent it is persuasive, can aid in that endeavor.
In this case, the Court of Appeals did not properly review the agency’s interpretation of the statute. Despite having understandable reservations about the agency’s interpretation, the Court affirmed the agency’s interpretation merely because it was “plausible.” [94]*94However, the plain language of the statute does not support the agency’s interpretation. Therefore, we reverse the Court of Appeals decision to uphold the agency’s construction of the statute. Under the proper interpretation of the statute, SBC Michigan (SBC)1 did not violate the statute as the Public Service Commission (PSC) had erroneously concluded. However, we agree with and affirm the conclusion of the Court of Appeals that the PSC had no jurisdiction over wiring inside a customer’s home. Thus, we remand this case to the PSC with the instruction that it must modify its August 1, 2005, order to eliminate any PSC regulation of “inside wiring.”
Accordingly, the Court of Appeals judgment is reversed in part and affirmed in part and the case is remanded to the PSC for further proceedings consistent with this opinion.
FACTS AND PROCEDURAL HISTORY
This case began in April 2001, when William J. and Sandra M. Rovas, SBC customers, called to report an interruption in their service. SBC sent a technician, who checked the wiring outside their home and erroneously determined that the problem was inside the customers’ home. Because the technician believed that the problem was inside the home, he left a note informing the customers that they would be charged $71 for the service call. Eventually, SBC realized the error and reversed the charge, but not before sending the customers a bill for the $71.
Despite the fact that SBC reversed the erroneously sent bill, the customers filed a complaint with the PSC [95]*95alleging, inter alia, a violation of § 2502(l)(a)2 of the Michigan Telecommunications Act, MCL 484.2101 et seq.3 The PSC agreed with the customers and found that SBC’s statements to the customers that (1) the problem was inside their home and (2) they owed SBC $71 for the service call were both “false,” and therefore, constituted violations of § 2502(1)(a). For erroneously sending a retracted $71 bill, the PSC fined SBC $15,000 for violating § 2502(l)(a).4
The Court of Appeals affirmed the PSC decision in an unpublished opinion per curiam, noting, however, that given the context of the term “false” in the statute, “it is plausible this provision is not intended to proscribe a statement that is simply not true or correct, but is only intended to proscribe those statements tending to deceive or mislead.”5
6Nonetheless, the Court of Appeals affirmed the PSC because the panel believed it was [96]*96“charged with giving great deference to the PSC’s construction of a statute which the Legislature has required the PSC to enforce, and therefore the mere establishment of an alternative interpretation of a statute to that given by the PSC will not satisfy [SBC’s] burden of proving the PSC’s interpretation was unlawful or unreasonable.”6 However, the panel was concerned that a portion of the PSC order implementing its interpretation was “ambiguous” and remanded for clarification. Specifically, the panel and SBC were concerned that the order required SBC to enter each consumer’s home to verify that the problem originated inside the house. This Court denied SBC’s interlocutory application for leave to appeal.7
On remand, the PSC clarified its order by noting that “SBC need not enter a customer’s premises every time that SBC is called upon to make a service trip”;8 however, SBC may not charge for services “if those services are reasonably necessary to diagnose problems attributable to its own facilities or exclude those facilities as a possible cause of service disruptions.”9
In a published opinion, the Court of Appeals affirmed in part and remanded to require the PSC to issue a modified order.10 In doing so, the panel relied on federal law and held that “inside wiring services” (services for problems with the wiring inside the customer’s home) were not subject to regulation by the PSC because such [97]*97problems are not within the PSC’s authority. Thus, the panel held that the PSC could not regulate “correct determination^ by SBC excluding its facilities as the cause of service disruption” because a correct determination that the problem originated inside the customer’s home necessarily involves “inside wiring.”11 Both the PSC and SBC have appealed to this Court, and this Court granted both applications.12
STANDARD OF REVIEW
As a general proposition, this Court reviews de novo questions of law, such as the proper interpretation of a statute.13 However, the primary issue in this case is the proper standard of review of an administrative agency’s construction of a statute. That standard of review is discussed below.
ANALYSIS
This case implicates the powers, and the boundaries of the powers, of all three branches: the Legislature, the judiciary, and administrative agencies, which are part of the executive branch.14 Thus, separation of powers principles will aid in the analysis of the proper consideration due an administrative agency’s interpretation of a statute.
The people of the state of Michigan have divided the powers of their government “into three branches: legislative, executive and judicial.”15 Furthermore, “[n]o [98]*98person exercising the powers of one branch shall exercise powers properly belonging to another branch except as expressly provided in this constitution.”16
“The legislative power of the State of Michigan is vested in a senate and a house of representatives.”17 Simply put, legislative power is the power to make laws.18 In accordance with the constitution’s separation of powers, this Court “cannot revise, amend, deconstruct, or ignore [the Legislature’s] product and still be true to our responsibilities that give our branch only the judicial power.”19 While administrative agencies have what have been described as “quasi-legislative” powers, such as rulemaking authority, these agencies cannot exercise legislative power by creating law or changing the laws enacted by the Legislature.20
Since the time of Marbury v Madison,21 interpreting the law has been one of the defining aspects of judicial power. “Although we may not usurp the lawmaking function of the legislature, the proper construction of a statute is a judicial function, and we are required to discover the legislative intent.”22 Administrative agen[99]*99cies exercise what have been described as “quasi-judicial” powers.23 However, such power is limited and is not an exercise of constitutional “judicial power.” The primary “judicial” function exercised by administrative agencies is confined to conducting contested cases, like the one at issue here. These administrative contested cases resemble trials. Constitutionally and statutorily, these administrative fact-finding exercises are entitled to a degree of deference defined by statute and our constitution.24 However, fact-finding in an administrative contested case, much like in a trial before a circuit court, is a far different endeavor than construing a statute.
I. REVIEW OF AN ADMINISTRATIVE AGENCY’S INTERPRETATION OF A STATUTE
With these separation of powers principles in mind, we now turn to the proper standard, under Michigan law, for reviewing an agency’s construction of a statute.
A. MICHIGAN JURISPRUDENCE
Unlike the United States Constitution, the Michigan Constitution specifically recognizes administrative agencies. Furthermore, the constitution explicitly provides for judicial review of administrative decisions:
All final decisions, findings, rulings and orders of any administrative officer or agency existing under the constitution or by law, which are judicial or quasi-judicial and affect private rights or licenses, shall be subject to direct review by the courts as provided by law. This review shall include, as a minimum, the determination whether such final decisions, findings, rulings and orders are authorized by law; and, in cases in which a hearing is required, [100]*100whether the same are supported hy competent, material and substantial evidence on the whole record. Findings of fact in workmen’s compensation proceedings shall be conclusive in the absence of fraud unless otherwise provided hy law.
In the absence of fraud, error of law or the adoption of wrong principles, no appeal may be taken to any court from any final agency provided for the administration of property tax laws from any decision relating to valuation or allocation.[25]
The constitutional provision provides for review to determine: (1) that the decision is authorized by law, and (2) if a hearing is required, that the decision is supported by record evidence.26 However, the provision does not stand for the proposition that agencies can assume this Court’s constitutional role as the final arbiter of the meaning of a statute.
Before evaluating the standard of review applicable to an agency’s interpretation of a statute, it is helpful to delineate the agency functions not at issue in this case. This distinction is important because there are different standards of review for different agency functions. As noted earlier, agencies perform both “quasi-legislative” [101]*101and “quasi-judicial” functions. First, there is the rule-making function. A reviewing court must determine whether the Legislature, in accordance with the separation of powers principles discussed, properly delegated authority to the agency to promulgate the rule at issue.27 That question concerns the constitutionality of the statute, a legal issue that this Court reviews de novo.28 If the Legislature has properly delegated the rulemaking authority, then the only question before the court is whether the agency “has exceeded its authority granted by the statute.”29
The other agency function not at issue in this case is fact-finding in contested cases. The constitution requires that such agency findings be “supported by competent, material and substantial evidence on the whole record.”30 Review of an administrative agency’s fact-finding is akin to an appellate court’s review of a trial court’s findings of fact in that an agency’s findings of fact are entitled to deference by a reviewing court. In its fact-finding capacity, the agency has reviewed evidence, such as witness testimony, and it is in the best position to evaluate the credibility and weight of that evidence. Similar to the clear error standard of review for circuit courts, under the constitutional and statutory standards of review, a reviewing court must ensure that the finding is supported by record evidence; however, the reviewing court does not conduct a new evidentiary hearing and reach its own factual conclusions, nor does the reviewing court subject the evidence to review de novo.31
[102]*102Keeping these other administrative functions distinct from review of an agency’s interpretation of a statute during a contested case is very important to ensure that the appellate court applies the proper standard of review. A review of our own cases suggests that when courts are unmindful of these differing functions, they also tend to muddle the distinct standards of review that apply to each. This Court has uniformly held that statutory interpretation is a question of law that this Court reviews de novo.32 Thus, concepts such as “abuse of discretion” or “clear error,” which are similar to the standards of review applicable to other agency functions, simply do not apply to a court’s review of an agency’s construction of a statute.
Nonetheless, the Court of Appeals panel in this case did not apply a de novo standard of review when assessing the PSC’s interpretation of MCL 484.2502(l)(a). While there are some opinions that seem to stand for the proposition that agency statutory interpretations are reviewed for “reasonableness” or an “abuse of discretion,”33 those standards do not apply to the interpretation of a statute, and they threaten the separation of powers principles discussed earlier by allowing the agency to usurp the judiciary’s constitutional authority to construe the law and infringe on the Legislature’s lawmaking authority.
However, “[w]e acknowledge that our past case law has not been entirely consistent regarding the subject of [103]*103the amount of deference to be given when an administrative agency with expertise in its field construes a statute governing the area regulated by the agency.”34 We believe that this is due in large part to the Court’s failure consistently to use the same articulation of the proper standard of review for an agency’s interpretation of a statute and to carefully apply the correct standards of review for different types of agency action.
This Court announced the proper standard of review for agency statutory construction more than 70 years ago in Boyer-Campbell v Fry,35 which dealt with the proper construction of the General Sales Tax Act. The Boyer-Campbell Court held that
the construction given to a statute by those charged with the duty of executing it is always entitled to the most respectful consideration and ought not to be overruled without cogent reasons. However, these are not binding on the courts, and [w]hile not controlling, the practical construction given to doubtful or obscure laws in their administration by public officers and departments with a duty to perform under them is taken note of by the courts as an aiding element to be given weight in construing such laws and is sometimes deferred to when not in conflict with the indicated spirit and purpose of the legislature.[36]
This standard requires “respectful consideration” and “cogent reasons” for overruling an agency’s interpretation. Furthermore, when the law is “doubtful or obscure,” the agency’s interpretation is an aid for discerning the Legislature’s intent. However, the agency’s interpretation is not binding on the courts, and it cannot conflict with the Legislature’s intent as expressed in the language of the statute at issue.
[104]*104Boyer-Campbell remains good law, and it has been used repeatedly by this Court.37 However, in some of our later cases, this Court and the Court of Appeals have employed recitations of standards that do not follow the language of Boyer-Campbell or apply to review of agency’s statutory construction. While these recitations do not necessarily substantively conflict with Boyer-Campbell, they add to the confusion discussed earlier.38 For example, inLudington Service Corp v Acting Comm’r of Ins, this Court affirmed the Court of Appeals decision to overturn one portion of the agency’s decision because the agency relied on an interpretation of a statute that conflicted with the statute’s plain meaning.39 First, the Court reversed a number of the agency’s factual determinations because they were not supported by “competent, material, and substantial evidence.”40 The Court then turned to the statutory interpretation question [105]*105and used the following standard of review in reaching that conclusion:
Finally, while this Court affords deference to an agency’s findings of fact, we can always review an agency’s legal findings. Both the Michigan Constitution and the applicable statute permit this Court to set aside the commissioner’s findings if they are in violation of the constitution or a statute, or affected by other substantial and material error of law.[41]
To that end, the Court held that “although this Court affords an agency some statutory deference, the agency’s interpretation is not binding on this Court, and cannot be used to overcome the statute’s plain meaning.”42 This standard does not directly conflict with Boyer-Campbell because the plain meaning of the statute still controlled the outcome; however, by referring to “deference” with regard to both the agency’s fact-finding and its statutory interpretation, the Court sowed the seeds of confusion.
Another example of a confusing articulation of the standard is illustrated in Adrian School Dist v Michigan Pub School Employee Retirement Sys,43 where this Court held that “[t]he agency must interpret the statute it administers, and its interpretations are entitled to great weight.” The case cited for this proposition, Magreta v Ambassador Steel Co,44 did not actually use the words “great weight,” but, rather, quoted the general Boyer-Campbell standard discussed earlier. While the Adrian School Dist Court independently construed the statute, by employing a term such as “great [106]*106weight,” this Court again allowed for the possibility that the judiciary must defer to the agency’s interpretation of the statute.
A similar blurring of standards occurred in Catalina Marketing Sales Corp v Dep’t of Treasury,45 in which this Court held that, while it “affords deference to the construction of statutory provisions by any particular department of the government and used for a long period, the department’s interpretation is not binding on this Court and cannot be used to overcome the statute’s plain meaning. . . .” Catalina adds the concept of deference to longstanding agency interpretations to the general deference referenced in Ludington:46 Like Ludington, Catalina recognizes the fundamental requirement that the statute’s plain meaning controls.47 Furthermore, the Court rejected the agency’s interpretation because it conflicted with the plain meaning.
Because this Court’s decisions that used imprecise language still made clear that the plain language of the statute was the controlling legal consideration, the varying deference standards articulated in them seem to have had negligible outcome determinative effect. [107]*107However, by employing words such as “deference,” which can imply that the judiciary must accede to the agency’s interpretation of a statute, this Court has unmistakably added to the confusion in this area of the law.48
Given this Court’s difficulty in hewing to the correct standard it set forth in Boyer-Campbell, the Court of Appeals has understandably relied on some of the confusing articulations of standards made by this Court and thereby used the erroneous “deference” or “great weight” standard to allow agencies improperly to assume the courts’ role as the final arbiter of a statute’s meaning. For instance, the Court of Appeals panel in this case quoted In re Michigan Cable Telecom Ass’n Complaint49 for the proposition that
[a]s a general rule, we will defer to the construction placed on a statute by the governmental agency charged with interpreting it, unless the agency interpretation is clearly erroneous. An agency’s initial interpretation of new legislation is not entitled to the same measure of deference as is a longstanding interpretation. However, merely establishing that smother interpretation of a statute is plausible does not satisfy a party’s burden of proving by clear and convincing evidence that the PSC’s interpretation is unlawful or unreasonable.
This hybrid “standard of review” is a prime example of the mixing and matching of the standards of review applicable to the different functions of an agency. Relying on this muddled and unduly deferential “standard,” the panel acceded to an agency interpretation that the [108]*108panel believed to be contrary to the plain meaning of the statute. When considering an agency’s statutory construction, the primary question presented is whether the interpretation is consistent with or contrary to the plain language of the statute. While a court must consider an agency’s interpretation, the court’s ultimate concern is a proper construction of the plain language of the statute.
By using a deferential standard inconsistent with Boyer-Campbell, the panel below abdicated its judicial authority to construe statutes. By acceding to the agency’s interpretation, the panel gave greater consideration to the agency’s interpretation than it would have given a circuit judge’s construction. Given that statutory construction is the domain of the judiciary, it is hard to imagine why a different branch’s interpretation would be entitled to more weight than a lower court’s interpretation. As established in Boyer-Campbell, the agency’s interpretation is entitled to respectful consideration and, if persuasive, should not be overruled without cogent reasons. Furthermore, the agency’s interpretation can be particularly helpful for “doubtful or obscure” provisions. But, in the end, the agency’s interpretation cannot conflict with the plain meaning of the statute.
“Respectful consideration” is not equivalent to any normative understanding of “deference” as the latter term is commonly used in appellate decisions. To avoid further confusion, courts should rely on the Boyer-Campbell articulation of the standard of review for an agency’s interpretation of a statute instead of more recent cases, which have erroneously introduced inappropriate concepts such as “deference.” Furthermore, courts should carefully separate the different agency [109]*109functions under consideration and apply the proper standard of review for each.
B. A NOTE ON THE FEDERAL CHEVRON50 DEFERENCE DOCTRINE
Some have urged that this Court adopt the Chevron deference doctrine, which federal courts use to review agency interpretations.51 The Chevron test requires the court to make two inquiries. First, the court must consider “whether Congress has directly spoken to the precise question at issue.”52 This inquiry may be dis-positive because “[i]f the intent of Congress is clear, that is the end of the matter; for the court, as well as the agency, must give effect to the unambiguously expressed intent of Congress.”53 The separation of powers principles discussed above provide the basis for this inquiry and result because “[t]he judiciary is the final authority on issues of statutory construction and must reject administrative constructions which are contrary to clear congressional intent.”54
However, “if the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency’s answer is based on a permissible construction of the statute.”55 The Chevron test for the permissibility of the agency’s construction differs slightly depending on whether Congress explicitly or [110]*110implicitly delegated authority to the agency “to fill any gap” left by Congress. “If Congress has explicitly left a gap for the agency to fill, there is an express delegation of authority to the agency to elucidate a specific provision of the statute by regulation.”56 An explicit delegation largely refers to the authority bestowed by Congress upon agencies to promulgate rules to enforce a statute.57 On the other hand, an implicit delegation arises when the legislation does not address a specific factual situation or where the statute is ambiguous.58
If Congress has given the agency an explicit delegation, then the “regulations are given controlling weight unless they are arbitrary, capricious, or manifestly contrary to the statute.”59 When the delegation is implicit, “a court may not substitute its own construction of a statutory provision for a reasonable interpretation [111]*111made by the administrator of an agency.”60 To that end, the Supreme Court has “recognized that considerable weight should be accorded to an executive department’s construction of a statutory scheme it is entrusted to administer, and the principle of deference to administrative interpretations.”61
While the Chevron inquiries are comparatively simple to describe, they have proven very difficult to apply.62 This Court has never adopted Chevron for review of state administrative agencies’ statutory interpretations, and we decline to adopt it now.63 The vagaries of Chevron jurisprudence do not provide a clear road map for courts in this state to apply when reviewing administrative decisions. Moreover, the unyielding deference to agency statutory construction required by Chevron conflicts with this state’s administrative law jurisprudence and with the separation of powers principles discussed above by compelling delegation of the judiciary’s constitutional authority to construe statutes to another branch of government. For these reasons, we decline to import the federal regime into Michigan’s jurisprudence.
II. PROPER INTERPRETATION OF MCL 484.2502(l)(a)
Having determined that agencies’ constructions of statutes are entitled to respectful consideration, but are [112]*112not binding on courts and cannot conflict with the plain language of the statute, we now turn to review § 2502(1)(a), which provides:
(1) A provider of a telecommunication service shall not do any of the following:
(a) Make a statement or representation, including the omission of material information, regarding the rates, terms, or conditions of providing a telecommunication service that is false, misleading, or deceptive.
The critical question here was the meaning of “false” and, thus, whether this statute penalized merely factually inaccurate statements, as the PSC concluded, or whether “false” includes a requirement that the inaccuracy be intentionally communicated. Importantly, the PSC did not actually provide an analysis for its “construction” of the statutory language. In its February 25, 2002, order, the PSC discussed the parties’ arguments concerning this section. The hearing referee had found that the “inaccuracies” at issue stemmed from the difficulties inherent in diagnosing the problem experienced by the SBC customers. SBC argued that the “misdiagnosis” in this case was not the type of activity proscribed by the statute and the hearing referee agreed. The customers and the PSC staff contrarily argued that any untrue statement was subject to the statutory sanctions. The PSC agreed with the customers and the PSC staff, rejecting the hearing referee’s application of the statute. In reaching that conclusion, the PSC first discussed three facts: (1) when the customers reported the problem, SBC’s automated system informed them that they would only be charged for problems with inside wiring; (2) the technician, without entering the customers’ house, informed the customers that the problem was inside and that the customers owed $71; and (3) the customers received an invoice for [113]*113$71 from SBC’s automated billing process, even though SBC had determined that the problem was with the outside wiring. The PSC then concluded that, “[b]ased on these facts, the company’s statements to [the customers] on April 3 and 4, 2001 were false,” and therefore, SBC violated § 2502(l)(a). However, the PSC did not conclude that the false statements were intended to deceive.64
In reaching this conclusion, the PSC did not analyze the language of the statute, nor did it provide a rationale for its unexplained conclusion that the statutory term “false” meant “untrue” or “incorrect.” The PSC’s bald assertion that SBC violated the statute is not a “construction” of the statute. Therefore, under the Boyer-Campbell standard, there is little here for any reviewing court to “respectfully consider.” The PSC, having failed to offer a construction of its own that would warrant any consideration, requires that we provide, as the panel below should have provided, an interpretation of the plain language of the statute.
The Court of Appeals acknowledged that “false” has multiple meanings, and the panel listed the following definitions:
“1. not true or correct; erroneous; wrong: a false statement. 2. uttering or declaring what is untrue; lying: a false witness. 3. not faithful or loyal; treacherous; hypocritical: a false friend. 4. tending to deceive or mislead; deceptive: a false impression .. . .”[65]
The panel indicated that it favored the “tending to deceive or mislead” fourth definition because of the statutory context. Furthermore, the panel stated that it [114]*114found insufficient evidence in the record to support an intent by SBC to mislead its customers. However, relying on an erroneous standard of review, the panel upheld the decision of the PSC because the agency’s interpretation “was quite literal and certainly not unlawful or unreasonable.”
By ignoring the statutory context, the PSC’s implicit interpretation of “false” was erroneous. “As a general matter, words and clauses will not be divorced from those which precede and those which follow. When construing a series of terms ... we are guided by the principle that words grouped in a list should be given related meaning.”66 In other words, this Court applies the doctrine of noscitur a sociis, which “stands for the principle that a word or phrase is given meaning by its context of setting.”67
The statute prohibits telecommunications providers from making “a statement or representation . . . that is false, misleading, or deceptive.”68 The context of the word “false” is the key to determining which of the multiple definitions of that term the Legislature intended, and the other related statutory terms— “misleading” and “deceptive” — provide that context. “Mislead” means “1. to lead or guide in the wrong direction. 2. to lead into error of conduct, thought, or judgment; lead astray,”69 and “deceive” means “to mislead by a false appearance or statement; trick.”70 Thus, [115]*115both “mislead” and “deceive” require the perpetrator intentionally to trick or lead astray his or her victim. These definitions provide insight into which “related meaning” of “false” the Legislature intended. The definition of “false” that has a related meaning to the other descriptive statutory terms is the fourth definition cited by the Court of Appeals: “tending to deceive or mislead; deceptive.” Thus, a mere mistaken communication would be insufficient to make a “false” statement penalized under this statute. The fact that the SBC’s technician’s statement was simply “untrue” or that a bill mistakenly sent in reliance on the technician’s incorrect diagnosis constitute insufficient proof to establish falsity required by the statute.71
Thus, we conclude that only statements that are intentionally false qualify as violations of the statute, and the Court of Appeals statutory construction determination and the PSC’s conclusion that a statutory violation occurred must be reversed.
III. THE PROPRIETY OF THE COURT OF APPEALS REMAND ORDER
In its first opinion, the Court of Appeals held that the remedy provision of the PSC’s February 25, 2002, order [116]*116was ambiguous and remanded for clarification. The Court was unsure whether the PSC required SBC to enter each customer’s home to verify that the problem stemmed from wiring inside the customer’s home. On remand, the PSC ruled:
The Commission should clarify the discussion section of its February 25, 2002 order to indicate that SBC need not enter a customer’s premises every time that SBC is called upon to make a service trip, but that it may not impose charges to recover the cost of services it provides to inspect, diagnose, and repair malfunctions covered by its tariff obligation, including the cost of conducting routine physical checks of its own facilities, in response to complaints or inquiries, if those services are reasonably necessary to diagnose problems attributable to its own facilities or exclude those facilities as a possible cause of service disruptions.[72]
In its second opinion, the Court of Appeals cited federal authority73 for the proposition that states were generally precluded from regulating services provided by telephone companies for “inside wiring.” However, states are free to regulate the telephone companies’ networks or “outside wiring.” On the basis of these principles, the panel took issue with the portion of the order directing “SBC not to impose charges for services that ‘exclude [SBC’s] facilities as a possible cause of service disruptions.’ ”74 The Court held that this sentence violated the federal regulations because “a correct determination by SBC excluding its facilities as the [117]*117cause of service disruption inherently constitutes a correct determination that the disruption was caused by the customer’s inside wiring.”75 The panel remanded to the PSC to remove any regulation of “inside wiring,” including fees attributable to correct determinations that the problem originated with the customer’s inside wiring.
The parties agree that SBC cannot charge for services performed for “outside wires” and that the PSC cannot regulate services on “inside wiring.” The issue is whether the PSC’s August 1, 2005, order is a permissible regulation of “outside wires” or an impermissible regulation of “inside wires.” We agree with the Court of Appeals that, to the extent the order prohibits SBC from charging for services associated with a problem caused by inside wiring, it is improper. While SBC may have to inspect its outside wires to confirm that a problem is with the customer’s inside wiring, the fact remains that if the problem is with the inside wiring, then SBC had to make a service call for an inside wiring problem. The PSC cannot regulate that service and must amend its order to eliminate that improper regulation.
CONCLUSION
With today’s decision, we reaffirm the Boyer-Campbell standard of review, which provides a longstanding and clear standard for appellate courts to apply to an administrative agency’s interpretation of a statute. In accordance with separation of powers principles and this Court’s older cases, we hold that agency interpretations are entitled to respectful consideration, but they are not binding on courts and cannot conflict [118]*118with the plain meaning of the statute. While the agency’s interpretation may be helpful in ascertaining the legislative intent, courts may not abdicate to administrative agencies the constitutional responsibility to construe statutes. Giving uncritical deference to an administrative agency would be such an improper abdication of duty.
Applying the proper standard to the statute at issue in this case, the PSC’s interpretation is erroneous, as was the panel’s undue deference to that construction. The Court of Appeals alternative interpretation (which it did not adopt) represents the proper interpretation of this statute. Under the appropriate interpretation of the statute, merely incorrect statements made with no intent to deceive are not subject to sanctions. Additionally, the PSC must modify its order to incorporate a correct construction of the statute and eliminate any regulation of inside wiring.
Taylor, C.J., and Corrigan and Markman, JJ, concurred with Young, J.
