DBA AT&T MICHIGAN CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE SIXTH CIRCUIT No. 10–313. Argued March 30, 2011—Decided June 9, 2011* The Telecommunications Act of 1996 requires incumbent local ex change carriers (LECs)—i.e., providers of local telephone service—to share their physical networks with competitive LECs at cost-based rates in two ways relevant here. First, 47 U. S. C. §251(c)(3) requires an incumbent LEC to lease “on an unbundled basis”—i.e., a la carte— network elements specified by the Federal Communications Commis sion (FCC) to allow a competitor to create its own network without having to build every element from scratch. In identifying those ele ments, the FCC must consider whether access is “necessary” and whether failing to provide it would “impair” the competitor’s provi sion of service. §251(d)(2). Second, §251(c)(2) mandates that incum bent LECs “provide . . . interconnection” between their networks and competitive LECs’ to ensure that a competitor’s customers can call the incumbent’s customers, and vice versa. The interconnection duty is independent of the unbundling rules and not subject to impairment analysis. In 2003, the FCC issued its Triennial Review Order deciding, con trary to previous orders, that §251(c)(3) did not require an incumbent LEC to provide a competitive LEC with cost-based unbundled access to existing “entrance facilities”—i.e., transmission facilities (typically wires or cables) that connect the two LECs’ networks—because such facilities are not network elements at all. The FCC noted, however, that entrance facilities are used for both interconnection and back hauling, and it emphasized that its order did not alter incumbent —————— * Together with No. 10–329, Isiogu et al. v. Michigan Bell Telephone Co. dba AT&T Michigan, also on certiorari to the same court. 2 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Syllabus LECs’ §251(c)(2) obligation to provide for interconnection. Thus, the practical effect of the order was only that incumbent LECs were not obligated to unbundle entrance facilities for backhauling purposes. In 2005, following D. C. Circuit review, the FCC issued its Trien nial Review Remand Order. The FCC retreated from the view that entrance facilities are not network elements, but adhered to its pre vious position that cost-based unbundled access to such facilities need not be provided under §251(c)(3). Treating entrance facilities as network elements, the FCC concluded that competitive LECs are not impaired without access to such facilities. The FCC again empha sized that competitive LECs’ §251(c)(2) right to obtain interconnec tion had not been altered. In the Remand Order’s wake, respondent AT&T notified competi tive LECs that it would no longer provide entrance facilities at cost based rates for either backhauling or interconnection, but would in stead charge higher rates. Competitive LECs complained to the Michigan Public Service Commission that AT&T was unlawfully ab rogating their §251(c)(2) right to cost-based interconnection. The Michigan Public Service Commission agreed and ordered AT&T to continue providing entrance facilities for interconnection at cost based rates. AT&T challenged the ruling. Relying on the Remand Order, the Federal District Court ruled in AT&T’s favor. The Sixth Circuit affirmed, declining to defer to the FCC’s argument that the order did not change incumbent LECs’ interconnection obligations, including the obligation to lease entrance facilities for interconnec tion. Held: The FCC has advanced a reasonable interpretation of its regula tions—i.e., that to satisfy its duty under §251(c)(2), an incumbent LEC must make its existing entrance facilities available to competi tors at cost-based rates if the facilities are to be used for interconnec tion—and this Court defers to the FCC’s views. Pp. 6–16. (a) No statute or regulation squarely addresses the question. Pp. 6–7. (b) Absent an unambiguous statute or regulation, the Court turns to the FCC’s interpretation of its regulations in its amicus brief. See, e.g., Chase Bank USA, N. A. v. McCoy, 562 U. S. ___, ___. The FCC proffers a three-step argument why its regulations require AT&T to provide access at cost-based rates to existing entrance facilities for interconnection purposes. Pp. 7–10. (1) Interpreting 47 CFR §51.321(a), the FCC first contends that an incumbent LEC must lease “technically feasible” facilities for in terconnection. Pp. 8–9. (2) The FCC contends, second, that existing entrance facilities are part of an incumbent LEC’s network, 47 CFR §51.319(e), and Cite as: 564 U. S. ____ (2011) 3 Syllabus therefore are among the facilities that an incumbent LEC must lease for interconnection, if technically feasible. P. 9. (3) Third, says the FCC, it is technically feasible to provide ac cess to the particular entrance facilities at issue in these cases—a point AT&T does not dispute. P. 10. (c) Contrary to AT&T’s arguments, the FCC’s interpretation is not “plainly erroneous or inconsistent with the regulation[s]. ” Auer v. Robbins, 519 U. S. 452, 461. First, it is perfectly sensible to read the FCC’s regulations to include entrance facilities as part of incumbent LECs’ networks. Second, the FCC’s views do not conflict with 47 CFR §51.5’s definition of interconnection as “the linking of two net works for the mutual exchange of traffic[, but not] the transport and termination of traffic.” Pp. 10–12. (d) Nor is there any other “reason to suspect that the [FCC’s] in terpretation does not reflect the agency’s fair and considered judg ment on the matter in question.” Auer, supra, at 462. AT&T incor rectly suggests that the FCC is attempting to require under §251(c)(2) what courts have prevented it from requiring under §251(c)(3) and what the FCC itself said was not required in the Re mand Order. Pp. 12–16. 597 F. 3d 370, reversed.

In these cases, we consider whether an incumbent pro­ vider of local telephone service must make certain trans­ mission facilities available to competitors at cost-based rates.

Opinion of the Court ties are to be used for interconnection: to link the incum­ bent provider’s telephone network with the competitor’s network for the mutual exchange of traffic. We defer to the Commission’s views and reverse the judgment below. I The Telecommunications Act of 1996 (1996 Act), 110 Stat. 56, imposed a number of duties on incumbent pro­ viders of local telephone service in order to facilitate mar­ ket entry by competitors. AT&T Corp. v. Iowa Utilities Bd., 525 U. S. 366, 371 (1999). The incumbent local ex­ change carriers (LECs) owned the local exchange net­ works: the physical equipment necessary to receive, prop­ erly route, and deliver phone calls among customers. Verizon Communications Inc. v. FCC, 535 U. S. 467, 490 (2002). Before the 1996 Act, a new, competitive LEC could not compete with an incumbent carrier without basically replicating the incumbent’s entire existing network. Ibid. The 1996 Act addressed that barrier to market entry by requiring incumbent LECs to share their networks with competitive LECs in several ways, two of which are rele­ vant here. First, 47 U. S. C. §251(c)(3) requires incumbent LECs to lease “on an unbundled basis”—i.e., a la carte— network elements specified by the Commission. This makes it easier for a competitor to create its own network without having to build every element from scratch. In identifying which network elements must be available for unbundled lease under §251(c)(3), the Commission is required to consider whether access is “necessary” and whether failing to provide access would “impair” a competitor’s provision of service. §251(d)(2). Second, §251(c)(2) mandates that incumbent LECs “provide . . . interconnection” between their networks and competitive LECs’ facilities. This ensures that customers on a com­ petitor’s network can call customers on the incumbent’s network, and vice versa. The interconnection duty is Cite as: 564 U. S. ____ (2011) 3 Opinion of the Court independent of the unbundling rules and not subject to impairment analysis. It is undisputed that both un­ bundled network elements and interconnection must be provided at cost-based rates. See §252(d)(1); Brief for Petitioner in No. 10–313, p. 28; Brief for Petitioners in No. 10–329, p. 7; Brief for Respondent 4. These cases concern incumbent LECs’ obligation to share existing “entrance facilities” with competitive LECs. Entrance facilities are the transmission facilities (typically wires or cables) that connect competitive LECs’ networks with incumbent LECs’ networks. The FCC recently adopted a regulation specifying that entrance facilities are not among the network elements that §251(c)(3) requires incumbents to lease to competitors on an unbundled basis at cost-based rates. See 47 CFR §51.319(e)(2)(i) (2005). The Commission noted, however, that it “d[id] not alter the right of competitive LECs to obtain interconnection facilities pursuant to section 251(c)(2).” In re Unbundled Access to Network Elements, 20 FCC Rcd. 2533, 2611, ¶140 (2005) (Triennial Review Remand Order). The specific issue here is whether respondent, Michigan Bell Telephone Company d/b/a AT&T Michigan (AT&T), must lease existing entrance facilities to competitive LECs at cost-based rates. The FCC interprets its regulations to require AT&T to do so for the purpose of interconnection. We begin by reviewing the Commission’s recent actions regarding entrance facilities and then explain the particu­ lar dispute that is before us today. A In 2003, the FCC decided, contrary to its previous or­ ders, that incumbent LECs were not obligated to provide cost-based unbundled access to entrance facilities under §251(c)(3). In re Review of Section 251 Unbundling Obli gations of Incumbent Local Exchange Carriers, 18 FCC Rcd. 16978, 17202–17205, ¶¶365–367 (2003) (Triennial 4 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court Review Order). Explaining that its previous approach had been “misguided” and “overly broad,” id., ¶¶366, 365, the Commission concluded that entrance facilities were not subject to the unbundling requirement because they are not network elements at all. See id., ¶366 (entrance facili­ ties “exist outside the incumbent LEC’s local network”). The Commission therefore did not conduct an impairment analysis. The FCC emphasized, however, the limits of this ruling. Entrance facilities are used for two purposes: interconnec­ tion and backhauling.2 It expressly “d[id] not alter” an incumbent LEC’s obligation under §251(c)(2) to provide “facilities in order to ‘interconnect with the incumbent LEC’s network.’ ” Id., ¶366 (brackets omitted). Thus, al­ though the Commission specified that §251(c)(3) did not require any unbundled leasing of entrance facilities, it determined in practical effect only that “incumbent LECs [were not obligated] to unbundle [entrance facilities] for the purpose of backhauling traffic.” Id., ¶365. On direct review, the D. C. Circuit questioned the Com­ mission’s determination that entrance facilities are not network elements under §251(c)(3), but found the agency rulemaking record insufficient and remanded to the Commission for further consideration. See United States Telecom Assn. v. FCC, 359 F. 3d 554, 586, cert. denied, 543 U. S. 925 (2004). The court noted that if entrance facilities were in fact “ ‘network elements,’ ” then “an analysis of —————— 2 Although the parties and their amici disagree over the precise defi­ nition of backhauling, they all appear to agree that backhauling is important to competitive LECs and occurs when a competitive LEC uses an entrance facility to transport traffic from a leased portion of an incumbent network to the competitor’s own facilities. Backhauling does not involve the exchange of traffic between incumbent and competitive networks. See, e.g., Brief for Petitioners in No. 10–329, p. 25; Brief for United States Telecom Association et al. as Amici Curiae 32. It thus differs from interconnection—“the linking of two networks for the mutual exchange of traffic.” 47 CFR §51.5 (2010). Cite as: 564 U. S. ____ (2011) 5 Opinion of the Court impairment would presumably follow.” 359 F. 3d, at 586. In 2005, the Commission responded. See Triennial Review Remand Order ¶¶136–141. The Commission re­ treated from its view that entrance facilities are not net­ work elements but adhered to its previous position that cost-based unbundled access to them need not be provided under §251(c)(3). Id., ¶¶137–138. Treating entrance facilities as network elements, the Commission concluded that competitive LECs are not impaired without access to them. Ibid. The Commission again emphasized that it “d[id] not alter the right of competitive LECs to obtain interconnection facilities pursuant to section 251(c)(2).” Id., ¶140. B In the wake of the Triennial Review Remand Order, AT&T notified competitive LECs that it would no longer provide entrance facilities at cost-based rates for either backhauling or interconnection, but would instead charge higher rates. Competitive LECs complained to the Michi­ gan Public Service Commission (PSC) that AT&T was unlawfully abrogating their right to cost-based intercon­ nection under §251(c)(2). The Michigan PSC agreed with the competitive LECs and ordered AT&T to continue providing entrance facilities for interconnection at cost­ based rates. AT&T challenged the Michigan PSC’s ruling in the District Court, which, relying on the Triennial Review Remand Order, ruled in AT&T’s favor. The Michigan PSC and several competitive LECs, including petitioner Talk America, Inc., appealed. The Court of Appeals for the Sixth Circuit affirmed over a dissent. Michigan Bell Telephone Co. v. Covad Commu nications Co., 597 F. 3d 370 (2010). At the court’s invita­ tion, the FCC filed a brief as amicus curiae, arguing that the Triennial Review Remand Order did not change in­ 6 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court cumbent LECs’ interconnection obligations, including the obligation to lease entrance facilities for interconnection. The Sixth Circuit declined to defer to the FCC’s views, 597 F. 3d, at 375, n. 6, and also expressly disagreed with the Seventh and Eighth Circuits, id., at 384–386 (discussing Illinois Bell Tel. Co. v. Box, 526 F. 3d 1069 (2008), and Southwestern Bell Tel., L. P. v. Missouri Pub. Serv. Comm’n, 530 F. 3d 676 (2008)).3 We granted certiorari, 562 U. S. ___ (2010), and now reverse. II Petitioners contend that AT&T must lease its existing entrance facilities for interconnection at cost-based rates. We agree. A No statute or regulation squarely addresses whether an incumbent LEC must provide access to entrance facilities at cost-based rates as part of its interconnection duty under §251(c)(2). According to the statute, each incum­ bent LEC has: “The duty to provide, for the facilities and equip­ ment of any requesting telecommunications carrier, interconnection with the local exchange carrier’s net­ work— “(A) for the transmission and routing of telephone exchange service and exchange access; “(B) at any technically feasible point within the car­ rier’s network; “(C) that is at least equal in quality to that provided by the local exchange carrier to itself or to any sub­ sidiary, affiliate, or any other party to which the car­ —————— 3 The Ninth Circuit has since joined the Seventh and Eighth Circuits.

S. ____ (2011) 7 Opinion of the Court rier provides interconnection; and “(D) on rates, terms, and conditions that are just, reasonable, and nondiscriminatory, in accordance with the terms and conditions of the agreement and the requirements of this section and section 252 of this title.” Nothing in that language expressly addresses entrance facilities. Nor does any regulation do so. See Brief for United States as Amicus Curiae 22, n. 6. AT&T contends that the statute makes clear that an incumbent LEC need not provide access to any facilities— much less entrance facilities—to provide interconnection. The company points out that §251(c)(2) does not mention incumbent LECs’ facilities, but rather mandates only that incumbent LECs provide interconnection “for the facilities and equipment of any [competing] carrier.” In contrast, AT&T notes, §251(c)(3) requires that incumbent LECs provide unbundled “access to [their] network elements.” We do not find the statute so clear. Although §251(c)(2) does not expressly require that incumbent LECs lease facilities to provide interconnection, it also does not ex­ pressly excuse them from doing so. The statute says nothing about what an incumbent LEC must do to “pro­ vide . . . interconnection.” §251(c)(2). “[T]he facilities and equipment of any [competing] carrier” identifies the equipment that an incumbent LEC must allow to inter­ connect, but it does not specify what the incumbent LEC must do to make the interconnection possible. Ibid. B In the absence of any unambiguous statute or regula­ tion, we turn to the FCC’s interpretation of its regulations in its amicus brief. See, e.g., Chase Bank USA, N. A. v. McCoy, 562 U. S. ___, ___ (2011) (slip op., at 12). As we reaffirmed earlier this Term, we defer to an agency’s interpretation of its regulations, even in a legal brief, 8 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court unless the interpretation is “ ‘plainly erroneous or incon­ sistent with the regulation[s]’ ” or there is any other “ ‘rea­ son to suspect that the interpretation does not reflect the agency’s fair and considered judgment on the matter in question.’ ” Id., at ___, ___ (slip op., at 12, 14) (quoting Auer v. Robbins, 519 U. S. 452, 461, 462 (1997)). The Commission contends that its regulations require AT&T to provide access at cost-based rates to its exist­ ing entrance facilities for the purpose of interconnection. The Commission’s interpretation proceeds in three steps. First, an incumbent LEC must lease “technically feasible” facilities for interconnection. Second, entrance facili- ties are among the facilities that an incumbent must make available for interconnection, if technically feasible. Third, it is technically feasible to provide access to the particular entrance facilities at issue in these cases. 1 The Commission first contends that an incumbent LEC must lease, at cost-based rates, any requested facilities for obtaining interconnection with the incumbent LEC’s network, unless it is technically infeasible to do so. Sec­ tion 251(c)(2) mandates that an incumbent LEC provide interconnection, at cost-based rates, “at any technically feasible point within the carrier’s network.” The FCC has long construed §251(c)(2) to require incumbent LECs to provide, at cost-based rates, “any technically feasible method of obtaining interconnection . . . at a particular point.” 47 CFR §51.321(a) (2010). The requirement in §51.321(a) to provide a “method of obtaining interconnection,” the Commission argues, en­ compasses a duty to lease an existing facility to a compet­ ing LEC. When the Commission originally promulgated §51.321(a), it explained that incumbent LECs would be required to “adapt their facilities to interconnection” and to “accept the novel use of, and modification to, [their] Cite as: 564 U. S. ____ (2011) 9 Opinion of the Court network facilities.” In re Implementation of Local Compe tition Provisions in the Telecommunications Act of 1996, 11 FCC Rcd. 15499, 15605, ¶202 (1996) (Local Competition Order). Since then, as AT&T and its amici concede, in­ cumbent LECs have commonly leased certain facilities at cost-based prices to accommodate interconnection. See Brief for Respondent 28–29; Brief for United States Tele­ com Association et al. as Amici Curiae 33–35. As additional support for its assertion that incumbent LECs are obligated to lease facilities, the FCC highlights the examples in §51.321(b) of “[t]echnically feasible meth­ ods of obtaining interconnection,” which include “[m]eet point interconnection arrangements.” In a meet-point arrangement, an incumbent LEC “accommodat[es]” inter­ connection by building a transmission facility from its network to a designated point, where it connects with the competitor’s corresponding transmission facility. Local Competition Order ¶553. Compared to that requirement, the Commission argues, the obligation to lease existing facilities for interconnection is quite modest. 2 Next, the Commission contends that existing entrance facilities are among the facilities that an incumbent LEC must lease for interconnection. According to the FCC, the Triennial Review Remand Order adopted a regulatory def­ inition that reestablished that entrance facilities are part of an incumbent LEC’s network. See ¶137; see also 47 CFR §51.319(e) (2005). The end of every entrance facility is therefore a “point within [an incumbent] car­ rier’s network” at which a competing LEC could request interconnection, 47 U. S. C. §251(c)(2), and each entrance facility potentially provides a “technically feasible method of obtaining interconnection,” 47 CFR §51.321(a) (2010). 10 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court 3 Finally, the FCC contends that providing access to the entrance facilities here for interconnection purposes is technically feasible. Under the Commission’s regulations, an incumbent LEC bears the burden of showing that a requested method or point of interconnection is technically infeasible. See 47 CFR §§51.305(e), 51.321(d); see also §§51.305(d), 51.321(c) (previously successful intercon­ nection is “substantial evidence” of technical feasibility). AT&T does not dispute technical feasibility here.4 C The FCC’s interpretation is not “plainly erroneous or inconsistent with the regulation[s]. ” Auer, supra, at 461 (internal quotation marks omitted). First, we disagree with AT&T’s argument that entrance facilities are not a part of incumbent LECs’ networks. Indeed, the Commis­ sion’s view on this question is more than reasonable; it is certainly not plainly erroneous. The Triennial Review Remand Order responded to the D. C. Circuit’s decision questioning the Commission’s earlier finding that en­ trance facilities are not network elements. It revised the definition of dedicated transport—a type of network —————— 4 These cases concern only existing entrance facilities, and the Com­ mission expressly declines to address whether it reads its regulations to require incumbent LECs to build new entrance facilities for intercon­ nection. Brief for United States as Amicus Curiae 25, n. 7. The Com­ mission suggests here, as it has before, that additional considerations of cost or reasonableness might be appropriate if a competitive LEC were to request that an incumbent LEC build new entrance facilities for interconnection. Ibid. (noting that the Commission’s Wireline Competi­ tion Bureau has declined to require an incumbent LEC to bear the entire cost of building new entrance facilities); see also Local Competi tion Order ¶553 (explaining with respect to meet-point arrangements that “the parties and state commissions are in a better position than the Commission to determine the appropriate distance that would constitute the required reasonable accommodation of interconnection”). We express no view on the matter. Cite as: 564 U. S. ____ (2011) 11 Opinion of the Court element—to include entrance facilities. Triennial Review Remand Order ¶¶136–137; see 47 CFR §51.319(e)(1) (defining dedicated transport to include “incumbent LEC transmission facilities . . . between wire centers or switches owned by incumbent LECs and switches owned by [competing] carriers”). Given that revised definition, it is perfectly sensible to conclude that entrance facilities are a part of incumbent LECs’ networks. Second, we are not persuaded by AT&T’s argument that the Commission’s views conflict with the definition of interconnection in §51.5. That regulation provides: “Inter­ connection is the linking of two networks for the mutual exchange of traffic. This term does not include the trans­ port and termination of traffic.” AT&T focuses on the definition’s exclusion of “transport and termination of traffic.” An entrance facility is a transport facility, AT&T argues, and it makes no sense to require an incumbent LEC to furnish a transport facility for interconnection when the definition of interconnection expressly excludes transport. We think AT&T reads too much into the exclusion of “transport.” The regulation cannot possibly mean that no transport can occur across an interconnection facility, as that would directly conflict with the statutory language. See §251(c)(2) (requiring “interconnection . . . for the transmission and routing of [local] telephone exchange service”). The very reason for interconnection is the “mu­ tual exchange of traffic.” 47 CFR §51.5; see also Competi tive Telecommunications Assn. v. FCC, 117 F. 3d 1068, 1071–1072 (CA8 1997) (“[T]he transmission and routing of telephone exchange service” is “what the interconnection, the physical link, would be used for” (internal quotation marks omitted)). The better reading of the regulation is that it merely reflects that the “transport and termination of traffic” is subject to different regulatory treatment than intercon­ 12 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court nection. Compensation for transport and termination— that is, for delivering local telephone calls placed by another carrier’s customer—is governed by separate stat­ utory provisions and regulations. See 47 U. S. C. §§251(b)(5), 252(d)(2); 47 CFR §51.701. The Commission explains that a competitive LEC typically pays one fee for interconnection—“just for having the link”—and then an additional fee for the transport and termination of tele­ phone calls. Tr. of Oral Arg. 28; see also Brief for United States as Amicus Curiae 3, n. 1. Entrance facilities, at least when used for the mutual exchange of traffic, seem to us to fall comfortably within the definition of intercon­ nection. See 597 F. 3d, at 388 (Sutton, J., dissenting) (noting that entrance facilities are “designed for the very purpose of linking two carriers’ networks” (internal quota­ tion marks omitted)). In sum, the Commission’s interpretation of its regula­ tions is neither plainly erroneous nor inconsistent with the regulatory text. Contrary to AT&T’s assertion, there is no danger that deferring to the Commission would effectively “permit the agency, under the guise of interpreting a regulation, to create de facto a new regulation.”5 Christen sen v. Harris County, 529 U. S. 576, 588 (2000). D Nor is there any other “reason to suspect that the inter­ pretation does not reflect the agency’s fair and considered judgment on the matter in question.” Auer, 519 U. S., at 462. We are not faced with a post-hoc rationalization by —————— 5 There is no merit to AT&T’s assertion that the FCC is improperly amending the list of “[t]echnically feasible methods of obtaining inter­ connection” set forth in 47 CFR §51.321(b). By its own terms, that list is nonexhaustive. See §51.321(b) (“[t]echnically feasible methods of obtaining interconnection . . . include, but are not limited to” the listed examples); see also §51.321(a) (“[A]n incumbent LEC shall provide . . . any technically feasible method of obtaining interconnection” (emphasis added)). Cite as: 564 U. S. ____ (2011) 13 Opinion of the Court Commission counsel of agency action that is under judicial review. See ibid.; see also Burlington Truck Lines, Inc. v. United States, 371 U. S. 156, 168–169 (1962) (“The courts may not accept appellate counsel’s post hoc rationaliza­ tions for agency action; [SEC v.] Chenery[ Corp., 332 U. S. 194 (1947),] requires that an agency’s discretionary order be upheld, if at all, on the same basis articulated in the order by the agency itself”). And although the FCC con­ cedes that it is advancing a novel interpretation of its longstanding interconnection regulations, novelty alone is not a reason to refuse deference. The Commission ex­ plains that the issue in these cases did not arise until recently—when it initially eliminated unbundled access to entrance facilities in the Triennial Review Order. Until then, the Commission says, a competitive LEC typically would elect to lease a cost-priced entrance facility under §251(c)(3) since entrance facilities leased under §251(c)(3) could be used for any purpose—i.e., both interconnection and backhauling—but entrance facilities leased under §251(c)(2) can be used only for interconnection. We see no reason to doubt this explanation. AT&T suggests that the Commission is attempting to require under §251(c)(2) what courts have prevented it from requiring under §251(c)(3) and what the Commission itself said was not required in the Triennial Review Re mand Order. Tr. of Oral Arg. 50 (“[T]his is a rear guard effort to preserve [cost-based] pricing for things that the [C]ommission has said should no longer be available . . . at [such] pricing”). We do not think that AT&T is correct. 1 To begin with, AT&T’s accusation does not square with the regulatory history. The Commission was not com­ pelled to eliminate the obligation to lease unbundled entrance facilities at cost-based rates. It is true that, prior to the Triennial Review orders, the 14 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court Commission twice unsuccessfully attempted to impose sweeping unbundling requirements on incumbent LECs. See Local Competition Order ¶278; In re Implementation of Local Competition Provisions of the Telecommunications Act of 1996, 15 FCC Rcd. 3696, 3771–3904, ¶¶162–464 (1999); see also 47 CFR §51.319 (1997); §51.319 (2000). Each time, the Commission’s efforts were rejected for taking an unreasonably broad view of “impair[ment]” under §251(d)(2). See Iowa Utilities Bd., 525 U. S., at 392; United States Telecom Assn. v. FCC, 290 F. 3d 415, 421– 428 (2002), cert. denied, 538 U. S. 940 (2003). In the Triennial Review Order, the Commission once again rein­ terpreted the “impair” standard and revised the list of network elements that incumbents must provide unbun­ dled to competitors. The Commission’s initial decision to eliminate the obli­ gation to unbundle entrance facilities, however, was not a result of the narrower view of impairment mandated by this Court and the D. C. Circuit. Instead, the Commis­ sion determined that entrance facilities need not be pro­ vided on an unbundled basis under §251(c)(3) on the novel ground that they are not network elements at all— something no court had ever suggested. Moreover, since its initial decision to eliminate the unbundling obligation for entrance facilities, the Commis­ sion has been committed to that position. When the D. C. Circuit questioned the Commission’s finding that entrance facilities are not network elements, the Commission re­ sponded by observing that the court “did not reject our conclusion that incumbent LECs need not unbundle en­ trance facilities, only the analysis through which we reached that conclusion.” Triennial Review Remand Order ¶137. The Commission then found another way to support that same conclusion. Cite as: 564 U. S. ____ (2011) 15 Opinion of the Court 2 More importantly, AT&T’s characterization of what the Commission has done, and is doing, is inaccurate. The Triennial Review orders eliminated incumbent LECs’ obli­ gation under §251(c)(3) to provide unbundled access to entrance facilities. But the FCC emphasized in both orders that it “d[id] not alter” the obligation on incumbent LECs under §251(c)(2) to provide facilities for interconnec­ tion purposes. Triennial Review Order ¶366; Triennial Review Remand Order ¶140. Because entrance facilities are used for backhauling and interconnection purposes, the FCC effectively eliminated only unbundled access to entrance facilities for backhauling purposes—a nuance it expressly noted in the first Triennial Review order. Tri ennial Review Order ¶365. That distinction is neither unusual nor ambiguous.6 In these cases, the Commission is simply explaining the interconnection obligation that it left undisturbed in the Triennial Review orders. We see no conflict between the Triennial Review orders and the Commission’s views expressed here.7 We are not concerned that the Triennial Review Re mand Order did not expressly distinguish between back­ —————— 6 The Commission has long recognized that a single facility can be used for different functions and that its regulatory treatment can vary depending on its use. Unbundled network elements, for example, may not be used for the exclusive provision of mobile wireless or long­ distance services. 47 CFR §51.309(b) (2010). Similarly, interconnection arrangements may be used for local telephone service but not for long­ distance services. §51.305(b). 7 The parties and their amici dispute whether an incumbent LEC has any way of knowing how a competitive LEC is using an entrance facility. This technical factual dispute simply underscores the appro­ priateness of deferring to the FCC. So long as the Commission is acting within the scope of its delegated authority and in accordance with prescribed procedures, it has greater expertise and stands in a better position than this Court to make the technical and policy judgments necessary to administer the complex regulatory program at issue here. 16 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. Opinion of the Court hauling and interconnection, though AT&T makes much of that fact. AT&T argues that the Commission’s holding in the Triennial Review Remand Order is broader than that in the Triennial Review Order. In AT&T’s view, the Commission concluded in the Triennial Review Remand Order that competitors are not impaired if they lack cost­ based access to entrance facilities for backhauling or interconnection. There are two flaws with AT&T’s reasoning. First, as we have discussed, the Triennial Review Remand Order reinstated the ultimate conclusion of the Triennial Review Order and changed only “the analysis through which [it] reached that conclusion.” Triennial Review Remand Order ¶137. Second, unlike §251(c)(3)’s unbundling obligation, §251(c)(2)’s interconnection obligation does not require the Commission to consider impairment. As the dissent below observed, it would be surprising indeed if the FCC had taken the novel step of incorporating impairment into interconnection without comment. 597 F. 3d, at 389 (opin­ ion of Sutton, J.). * * * The FCC as amicus curiae has advanced a reasonable interpretation of its regulations, and we defer to its views. The judgment of the United States Court of Appeals for the Sixth Circuit is reversed. It is so ordered. JUSTICE KAGAN took no part in the consideration or decision of these cases. Cite as: 564 U. S. ____ (2011) 1 SCALIA, J., concurring SUPREME COURT OF THE UNITED STATES _________________ Nos. 10–313 and 10–329 _________________ TALK AMERICA, INC., PETITIONER 10–313 v. MICHIGAN BELL TELEPHONE COMPANY DBA AT&T MICHIGAN ORJIAKOR ISIOGU, ET AL., PETITIONERS 10–329 v. MICHIGAN BELL TELEPHONE COMPANY DBA AT&T MICHIGAN ON WRITS OF CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE SIXTH CIRCUIT [June 9, 2011] JUSTICE SCALIA, concurring. I join the opinion of the Court. I would reach the same result even without benefit of the rule that we will defer to an agency’s interpretation of its own regulations, a rule in recent years attributed to our opinion in Auer v. Robbins, 519 U. S. 452, 461 (1997), though it first appeared in our jurisprudence more than half a century earlier, see Bowles v. Seminole Rock & Sand Co., 325 U. S. 410 (1945). In this suit I have no need to rely on Auer deference, because I believe the FCC’s interpretation is the fairest reading of the orders in question. Most cogently, ¶140 of the Trien nial Review Remand Order serves no purpose unless one accepts (as AT&T does not) the distinction between back­ hauling and interconnection that is referred to in footnotes to ¶¶138 and 141 of the order. 20 FCC Rcd. 2533, 2610– 2612 (2005). The order would have been clearer, to be sure, if the distinction had been made in a footnote to ¶140 2 TALK AMERICA, INC. v. MICHIGAN BELL TELEPHONE CO. SCALIA, J., concurring itself, but the distinction is there, and without it ¶140 has no point. It is comforting to know that I would reach the Court’s result even without Auer. For while I have in the past uncritically accepted that rule, I have become increasingly doubtful of its validity. On the surface, it seems to be a natural corollary—indeed, an a fortiori application—of the rule that we will defer to an agency’s interpretation of the statute it is charged with implementing, see Chevron U. S. A. v. Natural Resources Defense Council, Inc., 467 U. S. 837 (1984). But it is not. When Congress enacts an imprecise statute that it commits to the implementation of an executive agency, it has no control over that implemen­ tation (except, of course, through further, more precise, legislation). The legislative and executive functions are not combined. But when an agency promulgates an im­ precise rule, it leaves to itself the implementation of that rule, and thus the initial determination of the rule’s mean­ ing. And though the adoption of a rule is an exercise of the executive rather than the legislative power, a properly adopted rule has fully the effect of law. It seems contrary to fundamental principles of separation of powers to per­ mit the person who promulgates a law to interpret it as well. “When the legislative and executive powers are united in the same person, or in the same body of magis­ trates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact ty­ rannical laws, to execute them in a tyrannical manner.” Montesquieu, Spirit of the Laws bk. XI, ch. 6, pp. 151–152 (O. Piest ed., T. Nugent transl. 1949). Deferring to an agency’s interpretation of a statute does not encourage Congress, out of a desire to expand its power, to enact vague statutes; the vagueness effectively cedes power to the Executive. By contrast, deferring to an agency’s interpretation of its own rule encourages the agency to enact vague rules which give it the power, in Cite as: 564 U. S. ____ (2011) 3 SCALIA, J., concurring future adjudications, to do what it pleases. This frustrates the notice and predictability purposes of rulemaking, and promotes arbitrary government. The seeming inappro­ priateness of Auer deference is especially evident in cases such as these, involving an agency that has repeatedly been rebuked in its attempts to expand the statute beyond its text, and has repeatedly sought new means to the same ends. There are undoubted advantages to Auer deference. It makes the job of a reviewing court much easier, and since it usually produces affirmance of the agency’s view with­ out conflict in the Circuits, it imparts (once the agency has spoken to clarify the regulation) certainty and predict­ ability to the administrative process. The defects of Auer deference, and the alternatives to it, are fully explored in Manning, Constitutional Structure and Judicial Deference to Agency Interpretations of Agency Rules, 96 Colum. L. Rev. 612 (1996). We have not been asked to reconsider Auer in the present case. When we are, I will be receptive to doing so.
