MEMORANDUM OPINION 

July~' 2013 [Dkts. ##20, 23] 

Plaintiffs NACS (formerly, the National Association of Convenience Stores), 

National Retail Federation ("NRF"), Food Marketing Institute ("FMI"), Miller Oil Co., 

Inc. ("Miller"), Boscov's Department Store, LLC ("Boscov's) and National Restaurant 

Association ("NRA") (collectively, "plaintiffs") bring this action against the Board of 

Governors of the Federal Reserve System ("defendant" or "the Board") to overturn the 

Board's Final Rule setting standards for debit card interchange transaction fees 

("interchange fees") and network exclusivity prohibitions. Before the Court are the 

parties' cross-motions for summary judgment [Dkts. ##20, 23]. Upon consideration of 

the pleadings, oral argument, and the entire record therein, the Court concludes that the 

Board has clearly disregarded Congress's statutory intent by inappropriately inflating all 

1 
debit card transaction fees by billions of dollars and failing to provide merchants with 

multiple unaffiliated networks for each debit card transaction. Accordingly, the 

plaintiffs' motion is GRANTED and defendant's motion is DENIED. 

FACTUAL BACKGROUND 

Four of the six plaintiffs in this case are major trade associations in the retail 

industry. NACS is an international trade association comprised of more than 2,100 retail 

members and 1,600 supplier members in the convenience store industry, most located in 

the United States. Am. Compl. , 15 [Dkt. # 18]. NRF is "the world's largest retail trade 

association," representing department, specialty, discount, catalog, Internet, and 

independent stores, as well as chain restaurants, drug stores, and grocery stores in over 45 

countries. !d. , 17. FMI advocates for 1,500 food retailers and wholesalers, including 

large multi-store chains, regional firms, and independent supermarkets. !d., 19. NRA is 

the "leading national association representing th[ e] [restaurant and food-service] industry, 

and its members account for over one-third of the industry's retail locations." !d. , 23. 

According to plaintiffs, these trade associations and their members accept debit card 

payments and therefore are directly affected by the Board's interchange fee and network 

non-exclusivity regulations. !d. ,, 16, 18, 20, 23-25. 

The remaining plaintiffs are individual retail operations. Miller is a convenience 

store and gasoline retailer that also sells heating oil, heating and air-conditioning service, 

and commercial and wholesale fuels in the United States. !d. , 21. Boscov's is an instore and online retailer with a chain of forty full-service department stores located in five 

states in the mid-Atlantic region. !d. , 22. Both accept debit cards. See id. ,, 21-22.

The Board is a federal government agency responsible for the operation of the 

Federal Reserve System and promulgation of our nation's banking regulations. !d.~ 26. 

I. Debit Cards and Networks 

Although now ubiquitous, debit cards were first introduced as a form of payment 

in the United States in only the late-1960s and early-1970s. See Final Rule, Debit Card 

and Interchange Fees and Routing, 76 Fed. Reg. 43,394, 43,395 (July 20, 2011) (codified 

at 12 C.F.R. §§ 235.1-235.10) ("Final Rule"). Unlike other payment options, debit cards 

allow consumers to pay for goods and services at the point of sale using cash drawn 

directly from their bank accounts, and to withdraw and receive cash back as part of the 

transaction. !d. Prior to debit cards, consumers had to use paper checks or make inperson withdrawals from human bank tellers in order to access their accounts. !d. 

After decades of slow growth, the volume of debit card transactions increased 

rapidly in the mid-1990s, as did transactions involving other forms of electronic payment 

such as credit cards. !d. at 43,395 & n.5. This upsurge in debit card usage continued into 

the 2000s, reaching approximately 37.9 billion transactions in 2009. !d. at 43,395. By 

2011, debit cards were "used in 3 5 percent of noncash payment transactions, and have 

eclipsed checks as the most frequently used noncash payment method." !d. 

Most debit card transactions involve four parties, in addition to the network that 

processes the transaction. !d. at 43,395 & n.l4. These parties are: (1) the cardholder (or 

consumer), who provides the debit card as a method of payment to a merchant; (2) the 

issuer (or issuing bank), which holds the consumer's account and issues the debit card to 

the consumer; (3) the merchant, who accepts the consumer's debit card as a method of 

3 
payment; and (4) the acquirer (or acquiring bank), which receives the debit card 

transaction information from the merchant and facilitates the authorization, clearance, 

and settlement of the transaction on behalf of the merchant. !d. at 43,395-96. The 

network provides the software and infrastructure needed to route debit transactions; it 

transmits consumer account information and electronic authorization requests from the 

acquirer to the issuer; and it returns a message to the acquirer either authorizing or 

declining the transaction. See 15 U.S.C. § 1693o-2(c)(l1) (defining "payment card 

network"); 76 Fed. Reg. at 43,396. In addition, "[b ]ased on all clearing messages 

received in one day, the network calculates and communicates to each issuer and acquirer 

its net debit ... position for settlement." 76 Fed. Reg. at 43,396. 

There are two types of debit card transactions-PIN (or "personal identification 

number") and signature-each of which requires its own infrastructure. In a PIN 

transaction, the consumer enters a number to authorize the transaction, and the data is 

carried in a single message over a system evolved from automated teller machine 

("ATM") networks. !d. at 43,395. In a signature transaction, the consumer authenticates 

the transaction by signing something (like a receipt), and the data is routed over a dualmessage system utilizing credit card networks. !d. 1 "Increasingly, however, cardholders 

authorize 'signature' debit transactions without a signature and, sometimes, may 

authorize a 'PIN' debit transaction without a PIN." 76 Fed. Reg. at 43,395 & n.lO. 

1 See also Steven C. Salop et al., Economic Analysis of Debit Card Regulation Under 

Section 920 ~ 20 (Oct. 27, 2010) [Dkt. #33] (Joint Appendix 0332-0460) ("Salop"). 

4 
The vast majority of debit cards (excluding prepaid cards) support authentication 

by both PIN and signature, but which one is used in a given transaction depends in large 

part on the nature of the transaction and the merchant's acceptance policy. !d. at 43,395. 

For instance, hotel stays and car rentals are not easily processed on PIN-based systems 

because the transaction amount is unknown at the time of authorization. !d. Internet, 

telephone, and mail-based merchants also generally do not accept PIN transactions. !d. 

Of the eight million merchants in the United States that accept debit cards, the Board 

estimates that only one-quarter have the ability to accept PIN transactions. !d. 

II. Debit Card Fees 

There are several fees associated with debit card transactions. The largest is the 

interchange fee, which is set by the network and paid by the acquirer to the issuer to 

compensate the latter for its role in the transaction. !d. at 43,396; see also § 1693o2( c )(8) (defining "interchange transaction fee"). The network also charges acquirers and 

issuers a switch fee to cover its own transaction-processing costs. 76 Fed. Reg. at 

43,396; see also§ 1693o-2(c)(l0) (defining "network fee"). Once these fees are 

assessed, the acquirer credits the merchant's account for the value of its transactions, less 

a "merchant discount," which includes the interchange fee, network switch fees charged 

to the acquirer, other acquirer costs, and a markup. 76 Fed. Reg. at 43,396. 

5 
When PIN debit cards were first introduced, most regional networks set their 

interchange rates at "par," offering no cost subsidization to either merchants or issuers.2 

Some networks, however, implemented "reverse" interchange fees, which issuers paid to 

acquirers to offset the cost to merchants of installing terminals and other infrastructure 

needed to accept PIN at the point of sale. 76 Fed. Reg. at 43,396; Salop, supra note 1, 

~ 21; Mott, supra note 2, ~ 7. Because this model eliminated the costs associated with 

paper checks and human bank tellers, issuers could provide debit services at a profit, even 

without collecting interchange fees. 3 Furthermore, issuers touted the convenience of 

PIN-debit to their customers, and customers in tum maintained higher account balances, 

which issuers could loan out at a profit. Mott, supra note 2, ~ 3. 

As debit cards became more popular, interchange fee rates and the direction in 

which the fees flowed began to shift. See 76 Fed. Reg. at 43,396. By the early-2000s, 

acquirers were paying issuers ever-increasing interchange fees for PIN transactions. See 

id. Interchange fees for signature transactions, meanwhile, were modeled on credit card 

fees and were even higher than for PIN. I d.; Salop, supra note 1, ~ 23. 

In recent years, interchange fees have climbed sharply with PIN outpacing 

signature debit fees. From 1998 to 2006, merchants faced a 234 percent increase in 

interchange fees for PIN transactions, Mott, supra note 2, ~ 24, and by 2009, interchange

920 ~ 7 (Oct. 27, 201 0) [Dkt. #33] (Joint Appendix 0292-0331) ("Mott"); Salop, supra 

note 1, ~ 21.

Rulemaking on Debit Card Interchange Fees and Routing at 1 (Feb. 22, 2011) [Dkt. #33]

fee revenue for debit cards totaled $16.2 billion, 76 Fed. Reg. at 43,396. For most 

retailers, debit card fees represent the single largest operating expense behind payroll. 4 

Because debit card transaction fees, including interchange fees, are set by the 

relevant network and paid by the acquirer (on behalf of merchants) to the issuer, perhaps 

the best way to understand why such fees have skyrocketed over the past two decades is 

to recognize the market dynamics among the networks, issuers, and merchants. Although 

there are many debit card networks in the United States, networks under Visa's and 

MasterCard's ownership account for roughly 83 percent of all debit transactions and 

nearly 100 percent of signature transactions. 5 Visa also owns Interlink, the largest PIN 

network. 6 Due to their hefty market share, Visa and MasterCard exercise considerable 

market power over merchants with respect to debit card acceptance. See Salop, supra 

note 1, ~ 35. Hundreds of millions of consumers use cards that operate on Visa's and 

MasterCard's debit networks. !d. ~ 36. Merchants know that if they do not accept those 

cards and networks, they risk losing sales, and "losing the sale would be costlier to the 

merchant than accepting debit and paying the high interchange fee." !d. 

At the same time, Visa, MasterCard, and other debit networks vie for issuers to 

issue cards that run on their respective networks. !d. ~~ 33, 43. They can entice issuers

6 Salop, supra note 1, ~ 26. Today, there are approximately 15 PIN debit networks, the 

largest ofwhich are Interlink (owned by Visa), Star (owned by First Data Corp.), PULSE 

(owned by Discover), and NYCE (owned by FIS). !d. ~ 22.

by emphasizing their relative market power and ability to set interchange and other fees. 

/d.; see also 76 Fed. Reg. at 43,396. Networks thus have an incentive to continuously 

raise merchants' interchange fees-which, again, flow from merchants to issuers-as a 

way to attract issuers to the network. 7 Visa, for instance, more than tripled the Interlink 

interchange fee since the early-1990s, forcing small competitor PIN networks to increase 

their fees as well. Mott, supra note 2, ~~ 23-24; Salop, supra note 1, ~~ 40, 46. Within 

each network, issuers all receive the same interchange fee, regardless of their efficiency 

in processing transactions or their efforts to prevent fraud. See Durbin Comments, supra 

note 5, at 5, 9. 

In addition, Visa's and MasterCard's "Honor All Cards" rules force merchants that 

accept their networks' ubiquitous credit cards also to accept their signature debit cards 

with their corresponding high signature transactions fees. 8 As a practical matter, then, 

merchants cannot put downward pressure on interchange fees by rejecting networkaffiliated debit cards. Durbin Comments, supra note 5, at 2, 5. And issuers have 

implemented reward programs, special promotions, and penalty fees to encourage debit 

7 Salop, supra note 1, ~~ 34, 44; see also id. ~ 49 ("When debit networks raise their 

interchange fee, they gain issuance and cardholders, but they do not lose merchant 

acceptance."); Durbin Comments, supra note 5, at 5 ("[C]ompetition between networks 

does not lead to downward pressure on interchange rates because networks compete to 

attract issuers and do so by raising interchange fees."); MPC Comments, supra note 3, at 

1 ("As banks became accustomed to receiving high interchange rates ... which bore no 

relationship to costs ... a dynamic of merchants being forced to pay ever-increasing 

interchange rates to underwrite network competition for issuers became the norm for the 

industry.").

(especially signature-debit) usage. Mott, supra note 2, ,-r,-r 16-18; Salop, supra note 1, ,-r 

4 7. Merchants have responded by raising the price of goods and services to offset the 

fees. See Durbin Comments, supra note 5, at 5, 9; NRF Comments, supra note 8, at 5. 

The major card networks, not surprisingly, have also increased their own network 

fees, facilitated in part by exclusivity deals between the leading networks and debit 

issuers. Mott, supra note 2, ,-r,-r 26-27; Salop, supra note 1, ,-r,-r 30-31. Although there has 

been some network competition for PIN transactions, Visa and MasterCard have longstanding operating rules that disallow any other network from handling signature 

transactions on their cards. 76 Fed. Reg. at 43,396; Mott, supra note 2, ,-r,-r 26-27; Salop, 

supra note 1, ,-r,-r 30-31. Within the PIN market, too, Visa has agreements with particular 

issuers that create exclusivity via "volume commitments that are pegged to incentives 

such as reduced fees" or require that Interlink be their sole PIN debit network. Salop, 

supra note 1, ,-r 30. Thus, the dominant networks have been able to raise their network 

fees on merchants without concern for lost transaction volume because merchants have 

no other alternatives for routing transactions. !d. ,-r 31. According to information 

collected by the Board, total network fees exceeded $4.1 billion in 2009, with networks 

charging issuers and acquirers more than $2.3 billion and $1.8 billion, respectively. 76 

Fed. Reg. at 43,397. 

III. The Durbin Amendment 

On July 21, 2010, Congress passed legislation to address the rise of debit card 

fees. Coined the "Durbin Amendment" after its sponsor, Illinois Senator Richard J. 

Durbin, the legislation seeks to implement Section 920 of the Electronic Fund Transfer 

9 
Act ("EFTA"), 15 U.S.C. § 1693o-2, as enacted by Section 1075 ofthe Dodd-Frank Wall 

Street Reform and Consumer Protection Act ("Dodd-Frank Act"), Pub. L. No. 111-203, 

124 Stat. 1376, 2068-2074 (2010). The Durbin Amendment imposes various standards 

and rules governing debit fees and transactions. See id.; 76 Fed. Reg. at 43,394. The 

regulations apply only to issuers with assets exceeding $10 billion. § 1693o-2(a)(6)(A). 

A. Interchange Fees 

The Durbin Amendment first addresses interchange transaction fees, which are 

defined as "any fee established, charged or received by a payment card network for the 

purpose of compensating an issuer for its involvement in an electronic debit transaction." 

§ 1693o-2(c)(8). It provides that the fee charged by the issuer "with respect to an 

electronic debit transaction shall be reasonable and proportional to the cost incurred by 

the issuer with respect to the transaction." !d. § 1693o-2(a)(2) (emphasis added). It then 

directs the Board to establish standards to determine whether the amount of a debit card 

interchange fee is "reasonable and proportional to the cost incurred by the issuer" with 

respect to the transaction. !d. § 1693o-2(a)(3)(A). To promulgate these standards, 

Congress instructs the Board that it: 

shall-

(A) consider the functional similarity between-

(i) electronic debit transactions; and 

(ii) checking transactions that are required within the 

Federal Reserve bank system to clear at par; [and] 

(B) distinguish between10 
(i) the incremental cost incurred by an issuer for the role 

of the issuer in the authorization, clearance, or settlement of a 

particular electronic debit transaction, which cost shall be 

considered under[§ 1693o-2(a)(2)]; and 

(ii) other costs incurred by an issuer which are not specific 

to a particular electronic debit transaction, which costs shall 

not be considered under[§ 1693o-2(a)(2)] 

!d. § 1693o-2(a)(4)(A)-(B). 

Once the Board establishes this interchange transaction fee standard, Congress 

authorizes the Board to adjust the fee to allow for fraud-prevention costs, provided the 

issuer complies with standards established by the Board relating to fraud prevention: 

( 5) Adjustment to interchange transaction fees for fraud prevention costs 

(A) Adjustments. The Board may allow for an adjustment to the 

fee amount received or charged by an issuer under[§ 1693o-2(a)(2)], 

if-

(i) such adjustment is reasonably necessary to make 

allowance for costs incurred by the issuer in preventing fraud 

in relation to electronic debit transactions involving that 

issuer; and 

(ii) the issuer complies with the fraud-related standards 

established by the Board under[§ 1693o-2(a)(5)(B)], which 

standards shall-

(I) be designed to ensure that any fraud-related 

adjustment of the issuer is limited to the amount 

described in clause (i) and takes into account any 

fraud-related reimbursements (including amounts from 

charge-backs) received from consumers, merchants, or 

payment card networks in relation to electronic debit 

transactions involving the issuer; and 

(II) require issuers to take effective steps to reduce 

the occurrence of, and costs from, fraud in relation to 

electronic debit transactions, including through the 

11 
!d. § 1693o-2(a)(5)(A).9 

development and implementation of cost-effective 

fraud prevention technology. 

B. Network Regulation 

The Durbin Amendment also instructs the Board to regulate network fees by 

prescribing rules related to network non-exclusivity for routing debit transactions. 76 

Fed. Reg. at 43,394. Preferring a market-oriented approach to network fees, 10 the Durbin 

Amendment provides that the Board may regulate such fees only as necessary to ensure 

that they are not used to "directly or indirectly compensate an issuer with respect to an 

electronic debit transaction" or "circumvent or evade the restrictions ... and regulations" 

prescribed by the Board under this subsection. § 1693o-2(a)(8)(B)(i)-{ii). At the same 

time, the Amendment requires the Board to adopt rules that prohibit issuers and networks 

from entering into exclusivity arrangements or imposing restrictions on the networks 

through which merchants may route a transaction. Specifically, Congress directs the 

Board to promulgate regulations providing that issuers and networks "shall not directly or 

through any agent ... restrict the number of payment card networks 11 on which an 

9 This fraud-prevention cost adjustment was the subject of a separate rulemaking by the 

Board. See Final Rule, Debit Card and Interchange Fees and Routing, 77 Fed. Reg. 

46,258 (adopted Aug. 3, 2012) (codified at 12 C.F.R. § 235.4). 

10 "The term 'network fee' means any fee charged and received by a payment card 

network with respect to an electronic debit transaction, other than an interchange 

transaction fee." § 1693o-2(c)(l0). 

11 "Payment card network" is defined as "an entity that directly, or through licensed 

members, processors, or agents, provides the proprietary services, infrastructure, and 

software that route information and data to conduct debit card or credit card transaction 

authorization, clearance, and settlement, and that a person uses in order to accept as a 

form of payment a brand of debit card." § 1693o-2( c )(11 ). 

12 
electronic debit transaction may be processed" to one such network or two or more 

affiliated networks or "inhibit the ability of any person who accepts debit cards for 

payments to direct the routing of electronic debit transactions for processing over any 

payment card network that may process such transactions." § 1693o-2(b)(l)(A)-(B). 

IV. The Board's Rule 

After the enactment of the Dodd-Frank Act, the Board sought information from 

various industry participants to assist the agency in its initial rulemaking. The Board met 

with debit card issuers, payment card networks, merchant acquirers, consumer groups, 

and industry trade associations on a number of occasions to discuss a host of issues 

including debit transaction processing flows, transaction fee structures and levels, fraudprevention activities, fraud losses, routing restrictions, card-issuing arrangements, and 

incentive programs. 12 In September 2010, the Board circulated surveys to financial 

organizations with assets totaling $10 billion or more, networks that process debit card 

transactions, and the largest nine merchant acquirers in order to collect data on PIN, 

signature, and prepaid debit card operations and, for each card type, the costs associated 

with interchange and other network fees, fraud losses, fraud-prevention and data-security 

activities, network exclusivity arrangements, and debit-card routing restrictions. 75 Fed. 

Reg. at 81,724-25. In both the proposed and final rulemaking, the Board provided a 

12 Notice of Proposed Rulemaking, Debit Card Interchange Fees and Routing, 75 Fed. 

Reg. 81,722, 81,724 (proposed Dec. 28, 2010) (to be codified at 12 C.P.R.§§ 235.1-

235.10) ("NPRM"); see also Durbin Comments, supra note 5, at 2 (describing Board's 

"information-gathering process" as "notable for its transparency and thoroughness"). 

13 
detailed summary ofthe survey responses, see id. at 81,724-26; 76 Fed. Reg. at 43,397-

98, and upon issuing the Final Rule, it released a full report including survey statistics. 13 

A. Proposed Rule 

On December 28, 2010, the Board issued a NPRM implementing the Durbin 

Amendment and requesting public comments. 75 Fed. Reg. at 81,722. Stemming from 

its determination to include "only those costs that are specifically mentioned for 

consideration in the statute," the Board proposed that the interchange transaction fee 

standard be limited to the costs associated with the authorization, clearing, and settlement 

("ACS") of an electronic debit transaction that vary with the number of transactions sent 

to the issuer within the reporting period. !d. at 81,734-35, 81,739. The Board noted that, 

by focusing on the issuer's variable, per-transaction ACS costs, it was carrying out 

Congress's mandate to establish standards to assess whether an interchange fee is 

reasonable and proportional to the cost incurred by the issuer with respect to the 

transaction. !d. Consequently, in the NPRM, the Board suggested that network 

processing fees, 14 as well as fixed 15 and overhead 16 costs common to all debit transactions 

13 See generally Bd. of Governors of the Federal Reserve Sys., 2009 Interchange 

Revenue, Covered Issuer Cost, and Covered Issuer and Merchant Fraud Loss Related to 

Debit Card Transactions [Dkt. #33] (Joint Appendix 0261-0291), available at 

http://www .federalreserve.gov/paymentsystems/files/debit fees_ costs.pdf. 

14 75 Fed. Reg. at 81,735-36, 81,739; 76 Fed. Reg. at 43,424. The Board proposed in the 

NPRM that network fees be excluded from the interchange fee standard. 7 5 Fed. Reg. at 

81,73 5. Including them in allowable costs would risk putting merchants "in the position 

of effectively paying all network fees associated with debit card transactions" because 

"an acquirer would pay its own network processing fees directly to the network and 

would indirectly pay the issuer's network processing fees through the allowable costs 

included in the interchange fee standard." !d. 

14 
and not attributable to the ACS of any one transaction, be excluded from recovery under 

the interchange transaction fee standard. Fraud losses and the costs of fraud-prevention 

and reward programs were also deemed unallowable because they are not attributable to 

the variable ACS costs incurred by an issuer. 75 Fed. Reg. at 81,755, 81,760. 

While merchants overwhelmingly supported the Board's plan to limit allowable 

costs within the interchange transaction fee standard to only incremental ACS costs, 

networks and issuers advocated expanding the proposed set of allowable costs. 76 Fed. 

Reg. at 43,424-25. Indicating that its proposal was still subject to change, the Board 

"request[ ed] comment on whether it should allow recovery through interchange fees of 

the other costs of a particular transaction beyond authorization, clearing, and settlement" 

and, if so, "on what other costs of a particular transaction, including network fees paid by 

issuers for the processing of transactions, should be considered allowable costs." 75 Fed. 

Reg. at 81,735. 

15 The Board proposed that fixed costs-even if incurred for activities related to the ACS 

of debit card transactions-not be factored into allowable costs within the interchange fee 

calculus. 75 Fed. Reg. at 81,736 ("This [proposed] measure would not consider costs that 

are common to all debit card transactions and could never be attributed to any particular 

transaction [i.e., fixed costs], even ifthose costs are specific to debit transactions as a 

whole."). Indeed, the Board specifically contemplated that costs that do not vary with the 

number of transactions sent to the issuer over the calendar year, such as network 

connectivity fees and fixed costs of production, would be excluded as "unallowable, fixed 

costs," or "those costs that do not vary, up to existing capacity limits, with the number of 

transactions sent to the issuer over the calendar year," under the interchange transaction 

fee standard. !d. at 81,736, 81,739, 81,760. 

16 In the NPRM, the Board recommended that the cost of an issuer's facilities, human 

resources, and legal staff, as well as its costs in operating a branch office, be categorized 

as common overhead costs that cannot be allocated for the purpose of calculating its 

permissible interchange transaction fee. 75 Fed. Reg. at 81,735, 81,760. 

15 
Drawing on its comprehensive survey data relating to debit transaction fees, the 

Board proposed two alternative standards to govern interchange fees. The first, which 

the Board called "Alternative 1," allowed each issuer to recover its actual incremental 

ACS costs up to a safe harbor of seven cents ($.07) per transaction if the issuer chose not 

to determine its individual allowable costs, and up to a cap of twelve cents ($.12) if it did. 

75 Fed. Reg. at 81,736-38. The second, "Alternative 2," set a cap at a flat twelve cents 

($.12) per transaction. !d. at 81,738. 

With respect to network non-exclusivity for routing debit transactions, the Board 

requested comment on two alternative methods for implementation. The first, called 

"Alternative A," required at least two unaffiliated payment card networks active on each 

debit card, even if one network processed only signature transactions and one handled 

only PIN transactions. See 75 Fed. Reg. at 81,749. The second, "Alternative B" required 

at least two active unaffiliated payment card networks for each type of authorization 

method-i.e., at least two to process PIN transactions and two to process signature. 75 

Fed. Reg. at 81,749. In either case, issuers and networks could not inhibit a merchant's 

ability to direct the routing of an electronic debit transaction over any available network. 

!d. at 81,751. 

More than 11,500 commenters-including several of the named plaintiffs, as well 

as various issuers, payment card networks, consumers, consumer advocates, trade 

associations and members of Congress-replied to the Board's request for comment. 76 

16 
Fed. Reg. at 43,394. 17 In drafting the Final Rule, the Board relied on the voluminous 

comments, the statutory provisions, the available cost data, its understanding of the debit 

payment system, and other relevant information. 76 Fed. Reg. at 43,394. 

B. Final Rule 

The Board's Final Rule was published on July 20, 2011 and became effective on 

October 1, 20 11. See id. As its standard for assessing whether the interchange fee for a 

debit transaction is reasonable and proportional to the issuer's costs, the Board adopted "a 

modified version of proposed Alternative 2." Id. at 43,404. It permits each issuer to 

receive a fee as high as twenty-one cents ($.21) per transaction plus an ad valorem 

amount of five basis points ofthe transaction's value (0.05%). 12 C.P.R. § 235.3(b). 

The Board increased the allowable interchange fee (from twelve cents in 

Alternative 2 to twenty-one cents in the Final Rule) after concluding that the language 

and purpose of the Durbin Amendment allow the Board to consider additional costs not 

explicitly excluded from consideration by the statute. !d. at 43,426-27. According to the 

Board,§ 1693o-2(a)(4)(B) on the one hand requires the Board to consider incremental 

ACS costs incurred by issuers, and on the other hand prohibits consideration of any 

issuer costs that are not specific to a particular transaction; but it is silent with respect to 

costs that fall into neither category (e.g., costs specific to a particular transaction but are 

17 76 Fed. Reg. at 43,394; see generally Durbin Comments, supra note 5; FMI, 

Comments in Response to Notice of Proposed Rulemaking on Debit Card Interchange 

Fees and Routing (Feb. 22, 2011) [Dkt. #33] (Joint Appendix 0141-0148); NACS 

Comments, supra note 4; NRF Comments, supra note 8. 

17 
not incremental ACS costs). !d. at 43,426. The Board concluded that it had discretion to 

consider costs on which the statute is silent. !d. 

In setting the final interchange transaction fee standard, the Board considered all 

costs for which it had data, other than those prohibited under subsection (a)(4)(B). !d. 

Based on survey data and public comments, the Board found that issuers incur transaction 

costs other than the variable ACS costs that the Board originally proposed as the only 

allowable costs in the interchange fee, and that "no electronic debit transaction can occur 

without incurring these [non-variable ACS] costs, making them ... specific to each and 

every electronic debit transaction" under the statute. !d. at 43,427; see also id. at 43,404. 

Consequently, the Board amended its final interchange transaction fee standard to 

include, in addition to variable ACS costs: (1) fixed costs related to processing a 

particular transaction, such as network connectivity and software, hardware, equipment, 

and labor; (2) transaction monitoring costs; (3) an allowance for fraud losses (the ad 

valorem component); and (4) network processing fees. !d. at 43,404, 43,429-31. 18 

As to the network non-exclusivity rule, the Board concluded that "[t]he plain 

language of the statute does not require that there be two unaffiliated payment card 

networks available to the merchant for each method of authentication." !d. at 43,44 7; see 

also id. ("(T]he statute does not expressly require issuers to offer multiple unaffiliated 

signature and multiple unaffiliated PIN debit card network choices on each card." 

18 The Board still excluded from the final interchange transaction fee standard other costs 

not incurred as a consequence of effecting a transaction, including costs related to 

customer inquiries, reward programs, corporate overhead (e.g., executive compensation), 

establishing the account relationship, card production and delivery, marketing, research 

and development, and network membership fees. !d. at 43,404, 43,427-29. 

18 
(emphasis added)). Hence, the Board adopted Alternative A, which requires only that 

two unaffiliated networks be available for each debit card, not for each authorization 

method. 12 C.F.R. § 235.7(a)(2) & Official Cmt. 1; 76 Fed. Reg. at 43,404. 

On the same day that the Board adopted its Final Rule on debit card interchange 

fees and network non-exclusivity, it also published a separate Interim Final Rule on a 

proposed adjustment to the interchange fee for fraud-prevention costs under 15 U.S.C. 

§ 1693o-2(a)(5). See 76 Fed. Reg. at 43,478. The Board has since finished that 

rulemaking, and on August 2, 2012 it adopted a final rule governing the fraud-prevention 

cost adjustment. See 77 Fed. Reg. 46,258; 12 C.F.R. § 235.4. 19 

V. This Litigation 

On November 22, 2011, plaintiffs sued the Board, seeking a declaratory judgment 

that the Final Rule's interchange fee and network non-exclusivity provisions (12 C.F.R. 

§§ 253.3(b) and 235.7(a)(2)) are arbitrary, capricious, an abuse of discretion, and 

otherwise not in accordance with the law. See generally Compl. [Dkt. #1]. Moreover, 

plaintiffs seek costs and reasonable attorneys' fees pursuant to 28 U.S.C. § 2412, and 

such other relief as the Court deems reasonable and proper. See generally Am. Compl. 

Plaintiffs amended their complaint on March 2, 2012. !d. 

19 The Board allows issuers to "receive or charge an amount of no more than 1 cent per 

transaction in addition to any interchange transaction fee it receives or charges" if the 

issuer "develop[ s] and implement[ s] policies and procedures reasonably designed to take 

effective steps to reduce the occurrence of, and costs to all parties from, fraudulent 

electronic debit transactions, including through the development and implementation of 

cost-effective fraud-prevention technology." 12 C.F.R. § 235.4(a), (b)(l). 

19 
As individual retailers that accept debit cards and trade associations comprised of 

merchants, see supra p. 2, plaintiffs contend that the Final Rule is an unreasonable 

interpretation of the Durbin Amendment because it ignores Congress's directives 

regarding interchange fees and network exclusivity. See Am. Compl. ~~ 5, 11. As to the 

former, plaintiffs assert that the Durbin Amendment limits the Board's consideration of 

allowable costs to the "incremental cost" of "authorization, clearance and settlement of a 

particular electronic debit transaction," and that, by including other costs in the fee 

standard, the Board "acted unreasonably and in excess of its statutory authority." !d.~~ 

6, 70-73, 82-83. Regarding the latter, plaintiffs argue that the Board disregarded the 

plain meaning of the Durbin Amendment and misconstrued the statute by adopting a 

network non-exclusivity rule requiring all debit cards be interoperable with at least two 

unaffiliated payment networks, rather than requiring that all debit transactions be able to 

run over at least two unaffiliated networks. !d.~~ 9-10, 91-93. 

Plaintiffs moved for summary judgment on March 2, 2012, arguing that the Final 

Rule's interchange transaction fee and network non-exclusivity regulations should be 

declared invalid under the Administrative Procedure Act ("APA"), 5 U.S.C. § 706(2), 

because the Board impermissibly implemented the Durbin Amendment's statutory 

command and thus exceeded its authority. Pls.' Mot. for Summ. J. ("Pls.'s Mot.") at I 

[Dkt. #20]; Pis.' Mem. in Supp. ofPls.' Mot. for Summ. J. ("Pls.' Mem.") at 2 [Dkt.

consortium of major nationwide bank and credit union trade associations in the United 

20 
States;20 (2) Senator Richard J. Durbin, a member of Congress and the primary author of 

the Durbin Amendment;21 and (3) a group of convenience stores, quick-service 

restaurants and specialty coffee shops that operate small business franchises and licensed 

stores. 22 The latter two groups of amici filed briefs in support of plaintiffs' motion for 

summary judgment; the bank and credit union amici supported neither party. 

On Apri113, 2012, the Board filed a cross-motion for summary judgment. 

contending that plaintiffs' claims lack merit and that the Board is entitled to judgment as 

a matter oflaw. Def.'s Cross-Mot. for Summ. J. ("Def.'s Cross-Mot.") at 1 [Dkt. #23];

STANDARD OF REVIEW 

I. Summary Judgment 

Summary judgment is appropriate when the record evidence demonstrates that 

"there is no genuine dispute as to any material fact and the movant is entitled to judgment 

as a matter of law." Fed. R. Civ. P. 56( a); see also Celotex Corp. v. Catrett, 477 U.S. 

317, 322 ( 1986). The burden is on the moving party to demonstrate an "absence of a 

genuine issue of material fact" in dispute. Celotex, 477 U.S. at 323. In a case involving 

judicial review of final agency action under the APA, however, "the Court's role is 

limited to reviewing the administrative record." Air Transp. Ass 'n of Am. v. Nat 'l 

Mediation Bd., 719 F. Supp. 2d 26, 32 (D.D.C. 201 0) (citations omitted). "[T]he function 

of the district court is to determine whether or not as a matter of law the evidence in the 

administrative record permitted the agency to made the decision it did." Select Specialty 

Hosp.-Bloomington, Inc. v. Sebelius, No. 09-2362, 2012 WL 4165570, at *2 (D.D.C. 

Sept. 19, 2012) (citations and internal quotation marks omitted). 

II. Administrative Procedure Act 

Under the APA, the Court must set aside agency action that exceeds the agency's 

"statutory jurisdiction, authority, or limitations." 5 U.S.C. § 706(2)(C). To determine 

whether an agency has acted outside its authority, I must apply the two-step framework 

under Chevron, USA., Inc. v. Natural Res. Def Council, Inc., 467 U.S. 837 (1984). See 

Ass'n of Private Sector Colts. & Univs. v. Duncan, 681 F.3d 427,441 (D.C. Cir. 2012). 

A Chevron analysis first requires the reviewing court to determine "whether 

Congress has directly spoken to the precise question at issue." Chevron, 467 U.S. at 842. 

22 
To resolve whether "the intent of Congress is clear" under this first step, id., the court 

must exhaust the "traditional tools of statutory construction," including textual analysis, 

structural analysis, and (when appropriate) legislative history, id. at 843 n.9; Bell At!. Tel. 

Cos. v. FCC, 131 F.3d 1044, 1047 (D.C. Cir. 1997). "Ifthe 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." Chevron, 467 U.S. at 842-43. 

If after employing these tools, however, the Court concludes that the statute is 

silent or ambiguous on the specific issue, the Court moves on to step two and defers to 

any agency interpretation that is based on a permissible construction of the statute. !d. at 

843. An agency's construction is permissible "unless it is arbitrary or capricious in 

substance, or manifestly contrary to the statute." Mayo Found. forMed. Educ. & 

Research v. United States, 131 S. Ct. 704, 711 (2011) (citations and internal quotation 

marks omitted). "[T]he whole point of Chevron is to leave the discretion provided by the 

ambiguities of a statute with the implementing agency." Ass 'n of Private Sector Colts., 

681 F .3d at 441 (citations and internal quotation marks omitted). 

ANALYSIS 

I. Plaintiffs Have Met Their Burden of Production for Article III Standing. 

Curiously, the Board contends in a footnote that plaintiffs have failed to establish 

Article III standing because they failed in their opening brief to provide affidavits or 

other evidence that set forth specific facts demonstrating standing. See Def.'s Mem. at 13 

n.7 (citing Sierra Club v. EPA, 292 F.3d 895, 899 (D.C. Cir. 2002)). But reading on, the 

Sierra Club court explicitly recognized that: 

23 
In many if not most cases the petitioner's standing to seek review of 

administrative action is self-evident; no evidence outside the administrative 

record is necessary for the court to be sure of it. In particular, if the 

complainant is an object of the action (or forgone action) at issue-as is the 

case usually in review of a rulemaking ... -there should be little question 

that the action or inaction has caused him injury, and that a judgment 

preventing or requiring the action will redress it. 

292 F .3d at 899-900 (citation and internal quotation marks omitted). 

Indeed, our Court of Appeals has expressly rejected the use of the Sierra Club rule 

as a procedural "gotcha" in cases where standing was reasonably thought to be selfevident. See Am. Library Ass 'n v. FCC, 401 F.3d 489, 493-95 (D.C. Cir. 2005); see also 

Fundfor Animals, Inc. v. Norton, 322 F.3d 728, 733 (D.C. Cir. 2003) ("Sierra Club, 

however, does not require parties to file evidentiary submissions in support of standing in 

every case. To the contrary, our decision made clear that '[i]n many if not most cases the 

petitioner's standing to seek review of administrative action is self-evident."'). For 

instance, in American Library Association, our Circuit Court explained that interpreting 

Sierra Club as requiring long jurisdictional statements in opening briefs was inconsistent 

with precedent, a waste of judicial resources, and an unnecessary burden on litigants. 

401 F.3d at 494. Indeed, the court went on to clarify that Sierra Club need only 

"remind[] petitioners challenging administrative actions that, when they have good 

reason to know that their standing is not self-evident, they should explain the basis for 

their standing at the earliest appropriate stage in the litigation." !d. at 493. 

Here, plaintiffs had every reason to believe that their standing was self-evident and 

no cause to suspect that standing would be challenged in this court at all, much less in a 

24 
footnote on summary judgment! 23 Moreover, the administrative record contains 

countless examples of how plaintiffs are injured by the Board's interchange transaction 

fee and network non-exclusivity regulations. 24 Cf Am. Chemistry Council v. Dep 't of 

Transp., 468 F.3d 810, 822, 824 (D.C. Cir. 2006) (standing can be "self-evident" from 

the administrative record). The Board's own rulemaking recognizes that it is merchants 

that pay interchange and network fees and are thus directly affected by the Board's Final 

Rule regulating both. 25 See Fund for Animals, 322 F.3d at 734 ("[F]or the purpose of 

determining whether standing is self-evident, we see no meaningful distinction between a 

regulation that directly regulates a party and one that directly regulates the disposition of 

a party's property."). Accordingly, it was reasonable for each plaintiff to assume that it 

(or in the case of the trade associations, one of its members) would suffer an Article III 

injury when the Board's Final Rule was implemented. And in their reply brief, plaintiffs 

submitted declarations demonstrating what was already self-evident: that they will suffer 

cognizable harms as a result of the Board's regulations. See Pls.' Reply at 7-9; cf Cmtys. 

23 The Board chose not to file a motion to dismiss for lack of standing and gave plaintiffs 

no indication that it would challenge their claims on justiciability grounds. See Pis.' 

Reply Mem. in Supp. ofPls.' Mot. for Summ. J. and in Opp'n to Def.'s Mot. for Summ. 

J. ("Pls.' Reply") [Dkt. #26] at 7 n.3. 

24 See, e.g., 76 Fed. Reg. at 43,462 ("[I]it is possible that merchants with a large 

proportion of small-ticket transactions may experience an increase in total interchange 

fees .... "); id. at 43,448 ("Alternative A provides merchants fewer routing options with 

respect to certain electronic debit transaction compared to Alternative B."). 

25 See, e.g., 76 Fed. Reg. at 43,396 ("The interchange fee is set by the relevant network 

and paid by the [merchant] acquirer to the issuer .... [T]he [merchant] acquirer charges 

the merchant a merchant discount ... that includes the interchange fee"); 75 Fed. Reg. at 

81,727 ("[I]n point-of-sale transactions, these [network-exclusivity prohibition and 

routing] provisions improve the ability of a merchant to select the network that minimizes 

its cost ... and otherwise provides the most advantageous terms."). 

25 
Against Runway Expansion, Inc. v. FAA, 355 F.3d 678, 684-85 (D.C. Cir. 2004) 

(affidavits submitted with reply brief are sufficient under Sierra Club because they made 

associational standing "patently obvious" and respondent was not prejudiced). In short, 

plaintiffs have easily met their burden of production with regard to Article III standing 

here, and this Court will thus proceed to the merits. 

II. The Interchange Transaction Fee Regulation Is Invalid Under the APA. 

Plaintiffs contend that the Final Rule's interchange transaction fee standard, 12 

C.F.R. § 235.3(b), is plainly foreclosed by the text, structure, and purpose ofthe Durbin 

Amendment and is arbitrary, capricious, and contrary to law. According to plaintiffs, the 

plain language and legislative history of the statute make clear which issuer costs may be 

included in the interchange transaction fee standard, and the Board's inclusion of other 

costs cannot survive scrutiny under Chevron's first step. The Board, meanwhile, takes 

the position that the Durbin Amendment is silent, and therefore ambiguous, with respect 

to issuer costs not explicitly addressed in the statute. And because the final interchange 

fee provision is a reasonable construction of the statute, says the Board, it is entitled to 

Chevron deference. For the following reasons, I agree with the plaintiffs. 

A. The Durbin Amendment Plainly Limits the Costs Allowable Within the 

Interchange Transaction Fee Standard to Those Identified in 15 U.S.C. 

§ 1693o-2(a)( 4)(B)(i). 

Determining whether Congress has spoken to the precise question at issue through 

"the [statutory] language itself, the specific context in which that language is used, and 

the broader context of the statute as a whole" is, of course, this Court's first task. 

Robinson v. Shell Oil Co., 519 U.S. 337, 341 (1997). Our Court of Appeals has directed 

26 
this Court to use "all traditional tools of statutory interpretation, including text, structure, 

purpose, and legislative history, to ascertain Congress's intent at Chevron step one." 

Nat'l Cable & Telecomms. Ass 'n v. FCC, 567 F.3d 659, 663 (D.C. Cir. 2009) (citation 

and internal quotation marks omitted). If this examination yields a clear result, "then 

Congress has expressed its intention as to the question, and deference is not appropriate." 

Natural Res. Def Council, Inc. v. Daley, 209 F.3d 747, 752 (D.C. Cir. 2000). 

To discern the text's plain meaning, the Court is to look to "the language of the 

statute itself." Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 132 S. Ct. 1670, 1680 

(2012) (citation omitted). "[W]hen the statute's language is plain, the sole function of the 

courts-at least where the disposition required by the text is not absurd-is to enforce it 

according to its terms." Hartford Underwriters Ins. Co. v. Union Planters Bank, 530 

U.S. 1, 6 (2000) (citation and internal quotation marks omitted). "Unless otherwise 

defined, statutory terms are generally interpreted in accordance with their ordinary 

meaning." BP Am. Prod. Co. v. Burton, 549 U.S. 84, 91 (2006); see also FCC v. AT & T 

Inc., 131 S. Ct. 1177, 1182 (2011). 

An analysis of the statutory text, however "does not end here, but must continue to 

'the language and design of the statute as a whole."' Am. Scholastic TV Programming 

Found. v. FCC, 46 F.3d 1173, 1178 (D.C. Cir. 1995) (quoting Fort Stewart Sch. v. FLRA, 

495 U.S. 641,645 (1990)). 26 The Court must also "exhaust the traditional tools of 

26 See also Roberts v. Sea-Land Servs., Inc., 132 S. Ct. 1350, 1357 (2012) ("It is a 

fundamental canon of statutory construction that the words of a statute must be read in 

their context and with a view to their place in the overall statutory scheme." (citation 

omitted)); Bell Atl. Tel. Cos., 131 F.3d at 1047 ("The literal language of a provision taken 

27 
statutory construction, including examining the statute's legislative history to shed new 

light on congressional intent, notwithstanding statutory language that appears 

superficially clear." Sierra Club v. EPA, 551 F.3d 1019, 1027 (D.C. Cir. 2008) (citations 

omitted); see also AFL-C/0 v. FEC, 333 FJd 168, 172 (D.C. Cir. 2003) ("We consider 

the provisions at issue in context, using traditional tools of statutory construction and 

legislative history."). 

i. Subsection (a)(4)(B) Bifurcates the Universe of Electronic Debit 

Transaction Costs into the Allowable and the Impermissible. 

The Durbin Amendment instructs the Board to ensure that any interchange fee 

charged by an issuer "is reasonable and proportional to the cost incurred by the issuer 

with respect to the transaction," § 1693o-2(a)(3), and in so doing it must "distinguish 

between" two categories of costs. !d. § 1693o-2(a)( 4)(B)(i)-(ii). Plaintiffs contend that 

these categories bifurcate the entire universe of costs into two, and only two, groups: 

( 1) costs that are "incremental" or variable, incurred by an issuer for its role in the 

"authorization, clearance, or settlement," and that relate to a "particular" or single 

electronic debit transaction, which "shall be considered,"§ 1693o-2(a)(4)(B)(i) 

(emphasis added); and (2) "other costs" "incurred by an issuer which are not specific to a 

particular electronic debit transaction," which "shall not be considered," § 1693o2(a)(4)(B)(ii) (emphasis added). The Board disagrees, arguing that subsection (a)(4)(B) 

is silent when it comes to costs that are specific to a particular electronic debit transaction 

but that are not incremental ACS costs, as those costs do not fit into either subsection 

out of context cannot provide conclusive proof of congressional intent, any more than a 

word can have meaning without context to illuminate its use."'). 

28 
(a)(4)(B)(i) or (a)(4)(B)(ii). According to the Board, this creates ambiguity that the 

Board has the discretion to resolve. How convenient. 

Starting with subsection (a)(4)(B)'s text, I have no difficulty concluding that the 

statutory language evidences an intent by Congress to bifurcate the entire universe of 

costs associated with interchange fees. Indeed, Congress directed the Board to 

"distinguish between"-or, according to its plain and ordinary meaning, "separate into 

different categories" or "make a distinction"27-between: (1) incremental ACS costs 

relating to a particular transaction, which "shall be considered" in establishing the 

interchange transaction fee standard, and (2) "other costs" which are not specific to a 

particular transaction, which the Board "shall not" consider. § 1693o-2(a)(4)(B)(i)-(ii) 

(emphases added). By using strategically placed "shall" and "shall not" terms-which 

plainly indicate the inclusion of the first category of costs and exclusion of the secondCongress expressed its clear intent to separate costs that must be included in the 

interchange transaction fee standard and "other costs" that must be excluded. See Ass 'n 

ofCivilian Technicians, Mont. Air Chapter No. 29 v. Fed. Labor Relations Auth., 22 F.3d 

1150, 1153 (D.C. Cir. 1994) ("The word 'shall' generally indicates a command that 

admits of no discretion on the part of the person instructed to carry out the directive."). 

Furthermore, Congress used the inclusive phrase "other costs," as opposed to just 

"costs," to refer to those costs not to be considered in the interchange transaction fee 

27 Webster's New College Dictionary 337 (3d ed. 2008) (defining "distinguish" as "to 

recognize as being different or distinct; separate into different categories; perceive or 

indicate differences; discriminate"); Black's Law Dictionary 542 (9th ed. 2009) (defining 

"distinguish" as "to make a distinction"). 

29 
standard. The plain import of Congress's word choice, according to the ordinary 

definition of "other" and relevant case law, is that this second, prohibited category of 

"other costs" was intended to subsume all costs not explicitly addressed in the first, 

permissible category of costs. See Merriam- Webster's Collegiate Dictionary 878-79 

(11th ed. 2009) (defining "other" as "being the one (as of two or more) remaining or not 

included; being the one or ones distinct from that or those first mentioned or implied"). 28 

In other words, the plain text makes clear that the incremental ACS cost of a particular 

electronic debit transaction is the only cost the Board was expressly authorized to 

consider in its interchange transaction fee standard. 

The Board's counterargument-that Congress directed it not to consider "other 

costs incurred by an issuer which are not specific to a particular electronic debit 

transaction,"§ 1693o-2(a)(4)(B)(ii) (emphasis added), meaning that only costs "not 

specific to a particular ... transaction" are barred from consideration-is wholly 

unpersuasive. See De f.'s Mem. at 20-21. The non-restrictive pronoun "which" is a 

descriptor, rather than a qualifier, and Congress has repeatedly utilized this term to 

further describe the preceding phrase-here, "other costs"-rather than to condition or 

limit it. See United States v. Indoor Cultivation Equip. from High Tech Indoor Garden 

Supply, 55 F .3d 1311, 1315 (7th Cir. 1995) (concluding that Congress's use of the

intended the phrase "other incentive payment" to broadly cover abuses not enumerated);

pronoun "which," as in "[a]ll conveyances, including aircraft, vehicles, or vessels, which 

are used to ... facilitate [drug transactions]," did not limit the meaning ofthe word it 

amended, "conveyance," to a vehicle or vessel used or intended to be used to facilitate a 

drug transaction). 29 Not surprisingly, the Board fails to cite any persuasive definition or 

case law to the contrary, and its focus on commas is a red herring. See, e.g., Barrett v. 

Van Pelt, 268 U.S. 85, 91 (1925) ("Punctuation is a minor, and not a controlling, element 

in interpretation, and courts will disregard the punctuation of a statute, or re-punctuate it, 

if need be, to give effect to what otherwise appears to be its purpose and true meaning." 

(citation omitted)). 

Finally, statements by Senator Richard J. Durbin, the Amendment's chief sponsor, 

confirm that Congress intended to bifurcate the universe of costs into incremental ACS 

costs includable in the interchange transaction fee standard and all other costs to be 

excluded. Specifically, in addressing the meaning of the Amendment on the floor of the 

Senate prior to its final passage, Senator Durbin stated: 

Paragraph (a)( 4) [of the Amendment] makes clear that the cost to be 

considered by the Board in conducting its reasonable and proportional 

analysis is the incremental cost incurred by the issuer for its role in the 

authorization, clearance, or settlement of a particular electronic debit 

transaction, as opposed to other costs incurred by an issuer which are not 

specific to the authorization, clearance, or settlement of a particular 

electronic debit transaction. 

29 See also William Strunk Jr. & E.B. White, The Elements ofStyle 1, 3 (2d ed. 1972) 

(describing an "elementary rule[ ] of usage" that a "nonrestrictive clause is one that does 

not serve to identify or define the antecedent noun"); cf In re Connors, 497 F.3d 314, 

319 (3d Cir. 2007) ("The word 'that' is a relative pronoun that restricts and, therefore, 

modifies, the preceding noun[.]") 

31 
156 Cong. Rec. S5,925 (daily ed. July 15, 2010) (emphasis added). Although the Board 

admits that Senator Durbin's statement appears to divide the universe of costs into two 

categories, it argues nonetheless that the actual language of the statute overrides any floor 

statement by the bill's sponsor. See Def.'s Mem. at 20. Chevron, however, contemplates 

that legislative history-including history that does not match the text of the statute 

verbatim-will be read along with the statute to determine Congress's intent. See 

Chevron, 467 U.S. at 851-53, 862-64; Aid Ass 'nfor Lutherans v. US. Postal Serv., 321 

F.3d 1166, 1176-78 (D.C. Cir. 2003) (using legislative history, in tandem with plain 

language of statute, in Chevron step one). In this case, Senator Durbin's statement, read 

in conjunction with the statute's text, confirms that Congress intended to divide all costs 

into two categories: those that can and those that cannot be considered in setting the 

interchange fee standard. 

ii. Congress Intended to Exclude All Costs Other than the 

Incremental ACS Costs Incurred by the Issuer for a Particular 

Debit Transaction from the Interchange Fee Standard. 

Further parsing of the statute confirms that Congress intended to narrow the scope 

of costs considered in the interchange transaction fee standard. Subsection (a)( 4)(B)(i) 

directs the Board to include in the standard those ACS costs that are "incremental [to the] 

cost incurred by an issuer for the role of the issuer in ... a particular electronic debit 

transaction." § 1693o-2(a)(4)(B)(i) (emphasis added). The term "incremental" limits the 

includable costs to "variable, as opposed to fixed," ACS costs. Me. Pub. Serv. Co. v. 

32 
FERC, 964 F.2d 5, 9 (D.C. Cir. 1992).30 And the subsection includes only those costs 

incurred for the issuer's role in processing the transaction. § 1693o-2(a)(4)(B)(i). 

In addition, subsection (a)( 4 )(B)(ii) instructs the Board to exclude from the 

standard any "other costs incurred by an issuer which are not specific to a particular ... 

transaction." §1693o-2(a)(4)(B)(ii) (emphases added). Congress thus directed the Board 

to omit "other costs incurred by an issuer which are not [unique] to a [distinct or 

individual] transaction."31 The plain text of the Durbin Amendment thus precludes the 

Board from considering in the interchange fee standard any costs, other than variable 

ACS costs incurred by the issuer in processing each debit transaction. 

The Board contends that the statute's failure to define the terms "incremental cost" 

or "authorization, clearance, or settlement," or to delineate which types of costs are "not 

specific to a particular electronic debit transaction," renders those terms ambiguous, 

thereby giving the Board the authority to fill those statutory gaps. See Def. 's Mem. at 

26-27. Not quite! If I were to accept the Board's argument, then every term in the 

statute would have to be specifically defined or otherwise be deemed ambiguous. This 

result makes no sense, and more importantly, it is not the law. When a term is not 

defined in a statute, a court must assume that "the legislative purpose is expressed by the

defined as an average, variable and per-transaction cost that varies with the number of 

transactions); Webster's New College Dictionary 575 (3d ed. 2008) (defining 

"increment" as "a small positive or negative change in a variable").

omitted). 

"[T]he meaning of statutory language, plain or not, depends on context," King v. 

St. Vincent's Hasp., 502 U.S. 215,221 (1991), and the relevant provisions, statutory 

design, and legislative history here clearly support my reading of the statute. First, the 

statute's information collection provision explicitly requires public disclosure only of 

information "concerning the costs incurred, and interchange transaction fees charged or 

received ... in connection with the authorization, clearance or settlement of electronic 

debit transactions." § 1693o-2(a)(3)(B) (emphasis added). That disclosure is limited to 

the same costs specified in subsection (a)( 4 )(B )(i) reinforces that those ACS costs are the 

only ones Congress intended to include in the interchange transaction fee standard. 32 

Subsection (a)(4)(A) of the statute also directs the Board to consider the 

"functional similarity" between "electronic debit transactions" and "checking transactions 

that are required within the Federal Reserve bank system to clear at par" when 

prescribing standards used to assess whether an interchange transaction fee is reasonable 

and proportional to the issuer's transactions. § 1693o-2(a)(4)(A) (emphasis added). The 

Board is thus required to consider how debit and checking transactions are "like" or 

32 Conversely, if Congress had intended to provide the Board with discretion to consider 

additional, unspecified costs "that are specific to a particular electronic debit transaction 

but that are not incremental ACS costs," as the Board contends, Def.'s Mem. at 17, then 

Congress would have told the Board to report its findings concerning those costs, too. 

34 
"[r]esembling though not completely identical" in terms oftheir "capab[ility] of 

performing" or "ab[ility] to perform a regular function."33 Congress understood that 

debit card transactions are "akin to writing a check" because "[a]ll that happens ... is you 

deduct money from your bank account." See 156 Cong. Rec. S3,696 (daily ed. May 13, 

201 0) (statement of Sen. Richard J. Durbin) ("That is why debit cards are advertised as 

check cards."). However, as Senator Durbin explained, "there are zero transaction fees 

deducted when you use a check," unlike interchange fees, which "are deducted from 

every [debit] transaction left for the seller." !d. The Board even proposed in its NPRM 

to limit "allowable costs ... to those that the statute specifically allows to be considered, 

and not be expanded to include additional costs that a payor's bank in a check 

transaction would not recoup through fees from the payee's bank." 75 Fed. Reg. at 

81,73 5 (emphasis added). 

The Board argues that the plain language of subsection (a)(4)(A) merely requires 

the Board to consider the functional similarity between electronic debit transactions and 

checking transactions in determining its interchange fee standard (which it did) and does 

not preclude the Board's consideration of differences. "Were courts to presume a 

delegation of power absent an express withholding of such power," however, "agencies 

would enjoy virtually limitless hegemony, a result plainly out of keeping with 

Chevron[.]" Ry. Labor Execs. Ass'n v. Nar'l Mediation Bd., 29 F.3d 655,671 (D.C. Cir. 

33 Webster's New College Dictionary 1053 (3d ed. 2008) ("similar" defined as "like; 

resembling though not completely identical"); id. 462 (defining "functional" as "designed 

for or adapted for a specific function or use; capable of performing; operative"); 

Merriam-Webster's Collegiate Dictionary 507 (11th ed. 2009) ("functional" means 

"performing or able to perform a regular function"). 

35 
1994); see also Am. Bar Ass 'n v. FTC, 430 FJd 457, 468 (D.C. Cir. 2005) ("[l]fthere is 

the sort of ambiguity that supports an implicit congressional delegation of authority to the 

agency to make a deference-worthy interpretation of the statute, we must look elsewhere 

than the [statute's] failure to negate[.]"). In fact, it defies common sense to read an 

explicit directive to consider "functional similarity" as authorization to consider 

differences, as well 

Lastly, subsection (a)(5)(A)(i) directs the Board "to make allowance for costs 

incurred by the issuer in preventing fraud" via an "adjustment to the fee amount received 

or charged by an issuer" under the interchange fee standard. § 1693o-2(a)(5)(A)(i) 

(emphasis added). At first glance, Congress's choice of words here appears to sanction a 

wholesale inclusion of fraud-prevention costs within the interchange transaction fee 

standard. However, subsection (a)(5)(A)(i) limits "any fraud-related adjustment" to the 

amount "reasonably necessary ... to prevent[] fraud in relation to electronic debit 

transactions involving that issuer," and (a)(5)(A)(ii) conditions that adjustment on an 

issuer's compliance with fraud-related standards that "require issuers to take effective 

steps to reduce the occurrences and costs of, and costs from, fraud in relation to 

electronic debit transactions." § 1693o-2(a)(5)(A)(i)-(ii). Senator Durbin's discussion of 

subsection (a)(5) sheds further light on this provision: 

It should be noted that any fraud prevention adjustment to the fee amount 

would occur after the base calculation of the reasonable and proportional 

interchange fee amount takes place, and fraud prevention costs would not 

be considered as part of the incremental issuer costs upon which the 

reasonable and proportional fee amount is based. Further, any fraud 

prevention cost adjustment would be made on an issuer-specific basis, as 

each issuer must individually demonstrate that it complies with the 

36 
standards established by the Board, and as the adjustment would be limited 

to what is reasonably necessary to make allowance for fraud prevention 

costs incurred by that particular issuer. 

156 Cong Rec. S5,925 (daily ed. July 15, 2010) (statement of Sen. Richard J. Durbin) 

(emphases added); see also Durbin Comments, supra note 5, at 9. 

Accordingly, I find that the text and structure of the Durbin Amendment, as 

reinforced by its legislative history, are clear with regard to what costs the Board may 

consider in setting the interchange fee standard: Incremental ACS costs of individual 

transactions incurred by issuers may be considered. That's it! 

B. The Board's Interchange Fee Regulation Accounts for Costs That Are 

Unambiguously Foreclosed from Consideration by Congress. 

The Durbin Amendment is explicit about what costs the Board could consider in 

setting the interchange transaction fee, and the Board was required "to give effect to the 

unambiguously expressed intent of Congress." Chevron, 467 U.S. at 842-43. As the 

"final authority on issues of statutory construction," federal courts are charged with 

"reject[ing] administrative constructions which are contrary to clear congressional 

intent." !d. at 843 n.9. For the following reasons, I reject the Board's construction of the 

Durbin Amendment as non-compliant with Congress's clear mandate. 

First, the Board's understanding that a third category of costs can be recovered 

under the interchange transaction fee standard is irreconcilable with the statute. In its 

Final Rule, the Board concluded that it could, in its discretion, factor into the interchange 

fee any costs "that are specific to a particular electronic debit transaction but that are not 

incremental costs related to the issuer's role in authorization, clearance, and settlement." 

37 
76 Fed. Reg. at 43,426. According to the Board, the statute is silent as to costs not 

addressed in§ 1693o-2(a)(4)(B)(i) or (ii), and Congress did "not restrict the factors the 

Board may consider in establishing standards for assessing whether interchange 

transaction fees are reasonable and proportional to cost." 76 Fed. Reg. at 43,424. 34 

In exercising this purported discretion, the Board reads the statutory language 

prohibiting it from considering costs "not specific to a particular electronic debit 

transaction,"§ 1693o-2(a)(4)(B)(ii), as prohibiting it from considering only "those costs 

that are not incurred in the course of effecting any electronic debit transaction," 76 Fed. 

Reg. at 43,426 (emphasis added). The Board, to its credit, still did not consider costs 

associated with corporate overhead (e.g., executive compensation), establishing and 

maintaining an account relationship, debit card production and delivery, marketing, 

research and development, insufficient funds handling, network membership fees, reward 

programs, and customer support, id. at 43,427-29. But the Board did, contrary to the 

expressed will of Congress, consider "any cost that is not prohibited-i.e., any cost that 

is incurred in the course of effecting an electronic debit transaction," id. at 43,426, 

including fixed costs (i.e., network connectivity and software, hardware, equipment, and 

associated labor), network processing fees, transaction monitoring, and fraud losses, id. at 

34 See also id. at 43,426-27 ("[T]he requirement that one set of costs be considered and 

another set of costs be excluded suggests that Congress left to the implementing agency 

discretion to consider costs that fall into neither category to the extent necessary and 

appropriate to fulfill the purposes of the statute .... By considering all costs for which it 

had data other than prohibited costs, the Board has complied with the statutory mandate 

not to consider costs identified in [(a)(4)(B)(ii)], has fulfilled the statutory mandate 

requiring consideration of the costs identified in [(a)(4)(B)(i)], and has chosen to consider 

other costs specific to particular electronic debit transactions to the extent consistent with 

the purpose of the statute, in establishing its [interchange transaction fee] standard."). 

38 
43,429-31. As a result, the final regulation sets a maximum fee that an issuer could 

recover at twenty-one cents ($.21) per transaction, plus an ad valorem amount of .05% of 

each transaction's value, 12 C.F.R. § 235.3(b); 76 Fed. Reg. at 43,422-well above the 

NPRM's seven- ($.07) and twelve-cent ($.12) proposals, 75 Fed. Reg. at 81,736-38. 

This interpretation runs completely afoul of the text, design and purpose of the 

Durbin Amendment. By improperly narrowing the scope of excluded costs in subsection 

(a)(4)(B)(ii) to only those costs "not incurred in the course of effecting any electronic 

debit transaction," the Board expanded the range of allowable costs in subsection 

(a)( 4)(B)(i) to "any cost that is incurred in the course of effecting an electronic debit 

transaction." 76 Fed. Reg. at 43,326. In so doing, the Board not only ignored critical 

statutory terms such as "distinguish between," "other," "specific," "particular," 

"incremental," and "authorization, clearance, or settlement"35-which provide clear 

guidance, see supra pp. 28-30-but also shoehorned a whole array of excluded costs into 

the interchange fee standard. 

Under the Final Rule, it is inconsequential whether costs are variable and result 

only from an individual transaction or are fixed and common to all transactions; so long 

as a cost is incurred to effect "debit card transactions as a whole," the Board concluded 

that it may be considered in its interchange fee standard. 76 Fed. Reg. at 43,426; see also 

Def. 's Mem. at 27 ("The Board further determined that a cost is specific to a particular 

35 The Board somehow found that it was "not ... necessary to determine whether costs 

are 'incremental,' fixed or variable, or incurred in connection with authorization, 

clearance, and settlement," 76 Fed. Reg. at 43,427, even though those are operative 

words in the statute. 

39 
electronic debit transaction if no such transaction can occur without incurring that cost."). 

Please! This reading of the law contradicts Congress's clear mandate that the Board is 

precluded from considering all costs, other than an issuer's variable ACS costs related to 

an individual debit transaction, in setting the interchange standard. Costs that are "not 

specific to a particular debit transaction,"§ 1693o-2(a)(4)(B)(ii) (emphasis added), 

simply are not the same as costs that are "not specific to debit transactions as a whole," 

76 Fed. Reg. at 43,426 (emphasis added). And "the incremental cost incurred by an 

issuer for the role of the issuer in the authorization, clearance, or settlement of a 

particular electronic debit transaction,"§ 1693o-2(a)(4)(B)(i), is not the same as "any 

cost that is incurred in the course of effecting an electronic debit transaction," 76 Fed. 

Reg. at 43,426 (emphasis added). 

In short, the Board's interpretation is utterly indefensible. As explained above, the 

statute is not silent or ambiguous. Rather, the plain text of subsection (a)( 4)(B) and the 

statutory structure and legislative history of the Durbin Amendment clearly demonstrate 

that Congress intended for the Board to exclude all "other costs" not specified in the 

statute as requiring consideration in the interchange transaction fee standard. That 

Congress could have used other, more definitive language, as the Board argues, see 

De f.'s Mem. at 18-19, is irrelevant when its statutory import is nonetheless clear. 36 

36 See Locke, 471 U.S. at 95 ("[T]he fact that Congress might have acted with greater 

clarity or foresight does not give courts a carte blanche to redraft statutes in an effort to 

achieve that which Congress is perceived to have failed to do."); Brown v. Gardner, 513 

U.S. 115, 118 (1994) ("Ambiguity is a creature not of definitional possibilities but of 

statutory context .... "); S. Cal. Edison Co. v. FERC, 195 F.3d 17,24 (D.C. Cir. 1999) 

("[T]he court has repeatedly rejected the notion that the absence of an express

"[When] the agency has either violated Congress's precise instructions or exceeded the 

statute's clear boundaries then, as Chevron puts it, 'that is the end of the matter'-the 

agency's interpretation is unlawful." Vill. of Barrington, Ill. v. Surface Transp. Bd., 636 

F.3d 650, 660 (D.C. Cir. 2011) (quoting 467 U.S. at 842). 37 And it is quite clear that the 

statute did not allow the Board to consider the additional costs factored into the 

interchange fee standard-i.e., (1) fixed ACS costs, (2) transaction monitoring costs, 

(3) an allowance for an issuer's fraud losses, and (4) network processing fees. 76 Fed. 

Reg. at 43,429-31. How so? 

(1) Fixed ACS Costs. The final interchange fee standard includes total 

transaction processing costs, including costs reported as variable and fixed ACS costs, 

within allowable interchange fees. !d. at 43,429. Instead of citing statutory text to justify 

this interpretation of the law, the Board simply noted that it is administratively difficult to 

discern a transaction's incremental ACS costs. See id. at 43,426-27; Def.'s Mem. at 32-

proscription allows an agency to ignore a proscription implied by the limiting language of 

a statute[.]"); Engine Mfrs. Ass'n v. EPA, 88 F.3d 1075, 1088 (D.C. Cir. 1996) ("[I]f[the 

text] clearly requires a particular outcome, then the mere fact that it does so implicitly 

rather than expressly does not mean that it is 'silent' in the Chevron sense."). 

37 Moreover, Chevron step two is not implicated whenever a statute does not expressly 

negate the existence of a claimed administrative power, as the Board would have me 

believe. Rather, "it is only legislative intent to delegate such authority that entitles an 

agency to advance its own statutory construction for review under the deferential second 

prong of Chevron." City ofKan. City, Mo. v. Dep't ofHous. & Urban Dev., 923 F.2d 

188, 191-92 (D.C. Cir. 1991); Ethyl Corp. v. EPA, 51 F.3d 1053, 1060 (D.C. Cir. 1995) 

("We refuse, once again, to presume a delegation of power merely because Congress has 

not expressly withheld such power."). Put simply by plaintiffs, "[t]here is no indication 

in the Durbin Amendment's text, purpose, or legislative history that Congress meant, by 

carefully delineating the cost factors that the Board must consider and not consider in 

setting an interchange fee standard, to delegate to the Board by what it did not say the 

unbounded discretion to consider any other cost factor relating to a debit card 

transaction." Pis.' Mem. at 3 7. 

41 
33, 41. But Congress instructed the Board to consider only variable ACS costs incurred 

for the issuer's role in processing a particular transaction. See supra pp. 32-33. The 

legislative mandate to consider incremental ACS costs in setting the interchange standard 

is not a "minimum," as the Board argues, see Def.'s Mem. at 29, but rather a ceiling. The 

fact that "there is simply no bright line test to identify exactly ACS versus non-ACS 

costs," id. at 33, or that the Board "provided a reasoned explanation for considering 

certain fixed costs and excluding others," id. at 30, does not empower the Board to flout 

the statute and then brandish its Chevron defense. See Chevron, 467 U.S. at 843-44; Vill. 

of Barrington, 636 F.3d at 659-60. The Board's inclusion of fixed ACS costs in the 

interchange transaction fee standard was impermissible. 

(2) Transaction Monitoring Costs. The Board also included transaction 

monitoring costs-i.e., the costs of fraud-prevention activities that authenticate the 

cardholder and confirm whether a debit card is valid38-in the final standard because 

such costs are related to the authorization of a particular transaction. 76 Fed. Reg. at 

43,430-31. But according to the statutory language and the final Conference Report, 

Congress allowed for fraud-prevention costs only as a separate adjustment to, rather than 

a component of, the interchange transaction fee standard, and only if the issuer complies 

with fraud-related standards established by the Board. See § 1693o-2(a)(5)(A); supra pp. 

11-12, 36-3 7. In fact, subsection (a)( 5)' s adjustment to the interchange fee for fraud38 In both its NPRM and Final Rule, the Board classified transaction monitoring as fraudprevention activity. See 75 Fed. Reg. at 81,741 ("[I]ssuers engage in a variety of fraudprevention activities .... such as transaction monitoring[.]"); 76 Fed. Reg. at 43,397 

("The most commonly reported fraud-prevention activity was transaction monitoring."). 

42 
prevention costs was the subject of a distinct rulemaking. See 77 Fed. Reg. 46,258; 12 

C.P.R. § 235.4; supra notes 9, 19 and accompanying text. 

Although the Board recognizes that the plain language of subsection (a)(5)(A) 

provides a separate adjustment to the interchange transaction fee standard for fraudprevention costs, it nonetheless takes the position that the statute does not prohibit the 

consideration of those costs when setting the interchange fee standard. See Def.'s Mem. 

at 43. No so. It would be nonsensical for Congress to make fraud-prevention costs the 

basis for a conditional adjustment to the interchange fee standard, and at the same time 

implicitly allow for fraud-prevention costs to factor into the standard itself without any 

conditions being met. To the contrary, by linking the fraud-prevention adjustment with a 

statutory requirement that the issuer comply with fraud-related standards, Congress 

sought to prevent what the Board has allowed: rewarding every issuer with an 

interchange fee increase to cover fraud-prevenfion costs, regardless of whether the issuer 

complies with the fraud-related standards established under subsection (a)(5)(B). As 

Senator Durbin explained in a comment letter, "The current system of networkestablished interchange fees creates precisely the wrong incentives for issuers when it 

comes to fraud prevention" because "[ u ]nder the current system, all issuing banks in a 

network receive the same network-established interchange fee rates" regardless of 

whether they minimize actual fraud. Durbin Comments, supra note 5, at 9. "In contrast 

to the current inefficient system, [15 U.S.C. §1693o-2(a)(5)] will incentivize regulated 

43 
issuing banks to reduce fraud by allowing banks that take successful fraud prevention 

. . d . h fi " 'd 39 steps to receive mcrease mterc ange ees. 1, . 

(3) Allowance for Fraud Losses. The Board also included an allowance for 

fraud losses, or "losses incurred by the issuer, other than losses related to nonsufficient 

funds, that are not recovered through chargebacks to merchants or debits to or collections 

from customers," such as losses associated with lost, stolen, or counterfeit card fraud. !d. 

Not proposed for inclusion as an allowable cost in its NPRM, the Board concluded that 

fraud losses should be considered within the final interchange transaction fee standard 

because they "are generally the result of the authorization, clearance, and settlement of an 

apparently valid transaction that the cardholder later identifies as fraudulent." !d. 

(emphasis added). But the costs associated with the consequence of ACS-as opposed to 

ACS costs themselves-are not to be considered under the plain language of the statute. 

The Board's decision to "[p ]ermit[] issuers to recover at least some fraud losses through 

interchange fees ... given that the source of fraud could be any participant in an 

electronic debit transaction and that the exact source of fraud often is unknown," 76 Fed. 

Reg. at 43,431, is a blatant act ofpolicymaking that runs counter to Congress's will. 

(4) Network Processing Fees. Finally, the Board included network processing 

fees in the interchange fee standard because they are incurred for the issuer's role in ACS 

and are specific to a particular transaction. 76 Fed. Reg. at 43,430. Again, this ignores 

39 The Board tries to distinguish transaction monitoring from the types of activities 

considered under the separate fraud-prevention rulemaking, thereby rationalizing the 

inclusion of transaction monitoring costs in the interchange fee. See 76 Fed. Reg. at 

43,431. But the statute provides no basis for this distinction. 

44 
the plain language of the statute, which demonstrates that Congress did not intend for 

network fees to be incorporated into the interchange transaction fee standard. Under the 

statute's definitional provisions, a "network fee" is "any fee charged and received by a 

payment card network with respect to an electronic debit transaction, other than an 

interchange transactionfee." § 1693o-2(c)(l0) (emphasis added). Furthermore, 

subsection (a)(4)(B)(i) of the statute limits the Board's authority to permit recovery of 

issuer costs to those incurred "for the role of the issuer," not the network, in processing a 

transaction. § l693o-2(a)(4)(B)(i) (emphasis added); see supra p. 32-33. Last, 

subsection (a)(8)(B) states that the only authority Congress granted the Board to issue 

regulations regarding network fees is "to ensure that "(i) a network fee is not used to 

directly or indirectly compensate an issuer with respect to an electronic debit transaction; 

and (ii) a network fee is not used to circumvent or evade the restrictions of this subsection 

and regulations prescribed under such subsection." § 1693o-2(a)(8)(B). Thus, the 

interchange fee cannot be used to compensate an issuer for network fees. 

Ultimately, the Board asserts that it was given broad discretion to fill statutory 

gaps in establishing the interchange transaction fee standard. See Def. 's Mem. at 23-26. 

But even if this were true, which it is not, such discretion does not give the Board the 

authority to ignore the expressed will of Congress. See Bd. of Governors ofthe Fed. 

Reserve Sys. v. Dimension Fin. Corp., 474 U.S. 361, 374 (1986) ("The statute may be 

imperfect, but the Board has no power to correct flaws that it perceives in the statute it is 

empowered to administer. Its rulemaking power is limited to adopting regulations to 

carry into effect the will of Congress as expressed in the statute."); Ry. Labor Execs. 

45 
Ass 'n, 29 F .3d at 671 ('"Congress has directly spoken to the precise question at issue' in 

this case ... so there is no gap for the agency to fill." (citation omitted)). By including in 

the interchange fee standard costs that are expressly prohibited by the statute, the final 

regulation represents a significant price increase over pre-Durbin Amendment rates for 

small-ticket debit transactions under the $12 threshold. See 7-Eleven Amicus Br. at 17-

18; see also Durbin Amicus Br. at 23 ("[B]y setting a high fee cap that far exceeds the 

customary fees levied on small ticket transactions, the [Board] has given its regulatory 

blessing to the setting of interchange rates by Visa and MasterCard that are over three 

times larger than rates previously charged on small dollar transactions."). Congress did 

not empower the Board to make policy judgments that would result in significantly 

higher interchange rates. Accordingly, the Board's interpretation of the interchange fee 

standard is foreclosed by the law and must be invalidated under Chevron's first step. 

III. The Network Non-Exclusivity Regulation Is Invalid Under the APA. 

Subsection (b)(1)(A) ofthe Durbin Amendment directs the Board to issue 

regulations prohibiting issuers and networks from "restrict[ing] the number of payment 

card networks on which an electronic debit transaction may be processed" to one network 

or multiple affiliated networks. § 1693o-2(b)(l)(A). Subsection (b)(l)(B), meanwhile, 

instructs the Board to promulgate regulations that prohibit issuers and networks from 

"inhibit[ing] the ability of any person who accepts debit cards for payments to direct the 

routing of electronic debit transactions for processing over any payment card network 

that may process such transactions." § 1693o-2(b)(l)(B). The Board determined that 

subsection (b)(l)(A) requires issuers and networks to make available two unaffiliated 

46 
networks for each debit card, not for each method of authentication (signature and PIN). 

12 C.P.R.§ 235.7(a)(2) & Official Cmt. 1; see also 76 Fed. Reg. at 43,404,43,447-48. 

Plaintiffs argue that this interpretation disregards the statute's language and 

purpose, which require that merchants be given a choice between multiple unaffiliated 

networks not only for each card, but for each transaction. They say that the Board's nonexclusivity regulation cannot survive Chevron step one because it contravenes both the 

letter and spirit of the Durbin Amendment. The Board characterizes plaintiffs' arguments 

as being "unmoored from the statutory text," which the Board says is ambiguous on this 

issue. Moreover, the Board claims that its interpretation of the law is permissible and 

fully implements Congress's directive. I disagree. The plaintiffs' interpretation is, in my 

judgment, the one true to Congress's intent. How so? 

A. The Statute Requires that Merchants Be Provided with a Choice 

Between Multiple Unaffiliated Networks for Each Transaction. 

First, the Court must determine "whether Congress has directly spoken to the 

precise question at issue," Chevron, 467 U.S. at 84, by considering whether "the statute 

unambiguously forecloses the agency's interpretation, and therefore contains no gap for 

the agency to fill," Nat 'l Cable & Telecomms. Ass 'n v. Brand X Internet Servs., 545 U.S. 

967, 982-83 (2005). In determining whether Congress has spoken to the issue, the Court, 

of course, begins with the plain meaning of the statutory text. S. Cal. Edison, 195 F.3d at 

23. 

The language of the network non-exclusivity provision favors the plaintiffs' 

interpretation at Chevron step one. First, there is no question that subsection (b )(1 )(A) 

47 
mandates that "an issuer or payment card network shall not ... restrict the number of 

payment card networks on which an electronic debit transaction may be processed" to 

fewer than two unaffiliated networks, and that the Board must promulgate regulations to 

enforce this restriction. § 1693o-2(b)(l)(A) (emphasis added); see Zivotofsky v. Sec yof 

State, 571 F.3d 1227, 1243 (D.C. Cir. 2009) ("'Shall' has long been understood as 'the 

language of command."' (citation omitted)). Put differently, the statute instructs the 

Board to ensure that issuers and networks stop restricting merchants' ability to route each 

transaction over different networks. Congress's focus was on the number of networks 

over which each transaction-as opposed to each debit card-can be processed. 

Although the Board admits that the statute calls for debit cards to be able to 

function over two or more unaffiliated networks, it insists that the law is silent as to 

whether merchants must have routing choices for each transaction. De f.'s Reply to Pis.' 

Reply Mem. in Supp. of Pis.' Mot. for Summ. J. and in Opp'n to Def.'s Mot. for Summ. 

J. ("Def.'s Reply") at 31 [Dkt. # 32]. Congress resolved this uncertainty, however, by 

using the statutorily defined term "electronic debit transaction." See§ 1693o-2(c)(5) 

(defining "electronic debit transaction" as "a transaction in which a person uses a debit 

card"); id. § 1693o-2( c )(2)(A) ("debit card" defined as "any card ... issued or approved 

for use through a payment card network to debit an asset account ... whether 

authorization is based on signature, PIN, or other means"). When the definitions are read 

into the statute, subsection (b )(1 )(A) provides that networks and issuers "shall not ... 

restrict the number of payment card networks [to process] 'a transaction in which a 

person uses [any card ... issued or approved for use through a payment card network to 

48 
debit an asset account ... whether authorization is based on signature, PIN, or other 

means]"' to less than two unaffiliated networks. The plain text of the statute thus 

supports the conclusion that Congress intended for each transaction to be routed over at 

least two competing networks for each authorization method. 

Indeed, the Durbin Amendment's legislative history confirms my reading of the 

statute. It is axiomatic when interpreting a Congressional statute that this Court must 

consider, among other things, the problem Congress sought to resolve when it adopted 

the law at issue. PDK Labs. Inc. v. DEA, 362 F.3d 786, 796 (D.C. Cir. 2004). Even 

when the statute's plain meaning is clear from its terms, legislative history can be 

"equally illuminating." Planned Parenthood Fed'n of Am., Inc. v. Heckler, 712 F.2d 650, 

656-57 (D.C. Cir. 1983). 

As Senator Durbin explained, the Amendment was enacted at a time when 

network fees were on the rise due to exclusivity deals between dominant card networks 

and issuers. 40 Total network fees exceeded $4.1 billion in 2009, 76 Fed. Reg. at 43,397, 

due in large part to the lack of competition resulting from exclusivity agreements. As the 

Board explained in its NPRM: 

40 See 156 Cong. Rec. S10,996 (daily ed. Dec. 22, 2010) (statement of Senator Richard J. 

Durbin) ("In recent years ... the biggest networks like Visa have begun requiring banks 

to sign exclusive agreements under which they become the sole network on the banks' 

cards. This diminishes competition between networks and leads to higher prices. My 

amendment will restore this competition."); see also Durbin Comments, supra note 5, at 

11 ("This trend toward exclusivity agreements ... limits merchant and consumer choice; 

it diminishes competition by threatening to drive competing debit networks out of 

business; and it creates significant barriers to entry for new debit networks." (citation and 

internal quotation marks omitted)). 

49 
From the merchant perspective, the availability of multiple card networks 

on a debit card is attractive because it gives merchants the flexibility to 

route transactions over the network that will result in the lowest cost to the 

merchant. This flexibility may promote direct price competition among the 

debit card networks that are enabled on the debit card. Thus, debit card 

network exclusivity arrangements limit merchants' ability to route 

transactions over lower-cost networks and may reduce price competition. 

75 Fed. Reg. at 81,748. 

Congress adopted the network non-exclusivity and routing provisions "to inhibit 

the continued consolidation of the dominant debit networks' market power and to ensure 

competition and choice in the debit network market." Durbin Comments, supra note 5, at 

11; see also 156 Cong. Rec. S5,926 (daily ed. July 15, 2010) (statement of Sen. Richard 

J. Durbin) ("All these provisions say is that [f]ederallaw now blocks payment card 

networks from engaging in certain specific enumerated anti-competitive practices, and 

the provisions describe precisely the boundaries over which payment card networks 

cannot cross with respect to these specific practices."). It is clear that Congress intended 

to put an end to exclusivity agreements and increase merchants' choice among debitprocessing networks, not restrict that choice or even preserve the status quo. 

Accordingly, it defies both the letter and purpose of the Durbin Amendment to 

read the statute as allowing networks and issuers to continue restricting the number of 

networks on which an electronic debit transaction may be processed to fewer than two 

per transaction. Indeed, prior to the Amendment's passage, Senator Durbin explicitly 

confirmed that Congress wanted subsection (b )(I )(A) to ensure the availability of at least 

two competing networks for each method of cardholder authentication on which an 

electronic debit transaction may be processed: 

50 
This paragraph is intended to enable each and every electronic debit 

transaction-no matter whether that transaction is authorized by signature, 

PIN, or otherwise-to be run over at least two unaffiliated networks, and 

the Board's regulations should ensure that networks or issuers do not try to 

evade the intent of this amendment by having cards that may run on only 

two unaffiliated networks where one of those networks is limited and 

cannot be used for many types of transactions. 

156 Cong. Rec. S5,926 (daily ed. July 15, 2010) (statement of Sen. Richard J. Durbin) 

(emphases added). In short, Congress adopted the network non-exclusivity and routing 

provisions to ensure that for multiple unaffiliated routing options were available for each 

debit card transaction, regardless ofthe method of authentication. The Board's Final 

Rule not only fails to carry out Congress's intention; it effectively countermands it! 

B. The Board's Network Non-Exclusivity Regulation Is Inconsistent with 

the Statute. 

The Board's network non-exclusivity regulation requires at least two unaffiliated 

payment card networks be enabled on each debit card, meaning that a card complies with 

the regulation if it has been enabled with only one PIN network and one signature 

network. 12 C.F.R. § 235.7(a)(2) & Official Cmt. 1; see also 76 Fed. Reg. at 43,447-48. 

According to the Board, "[t]he plain language of the statute does not require that there by 

two unaffiliated payment card networks available to the merchant for each method of 

authentication." 76 Fed. Reg. at 43,447. I disagree. 

The Board's interpretation of subsection (b)(l)(A) cannot be reconciled with the 

plain meaning or spirit of the statute because it still allows networks and issuers to make 

only one network available for many transactions. Indeed, by the Board's own 

admission, several common transaction types cannot be authenticated using the PIN 

51 
method, leaving signature-debit as the only available option. See 76 Fed. Reg. 43,395. 

"[H]otel stays or car rentals," not to mention "Internet, telephone, and mail transactions," 

are typically incompatible with PIN authorization technology. !d. Under a rule that 

allows issuers to provide just one signature network and one PIN network per card, 

merchants in these signature-only industries are left with no network options. See 75 

Fed. Reg. at 81,748. This result cannot be reconciled with Congress's goal of providing 

all merchants with a choice between multiple unaffiliated networks for every transaction. 

The Board contends that where a merchant can process both signature and PIN 

transactions, the customer determines the authentication method at the point of sale by 

choosing "debit" for PIN authentication or "credit" for signature authentication. 76 Fed. 

Reg. at 43,448. In this scenario, the Board says that its network non-exclusivity rule 

technically provides for multiple available networks, but "the consumer, and not the 

issuer or the payment card network, ... restrict[ s] the available routing choices" for the 

merchant. !d. The Board forgets, however, that it is issuers and networks who establish 

the availability of different routing options, well before consumers ever enter the picture. 

And the Board cannot be relieved of its statutory obligation to ensure that network and 

issuer practices do not inhibit merchant choice simply because, in many transactions, 

consumers choose the authentication method. In the end, any reading that denies 

merchants the ability to choose between multiple networks for each transaction cannot be 

squared with a statute that plainly requires at least two networks per transaction. 

The Board's network non-exclusivity regulation is also inconsistent with other 

related statutory provisions. For example, subsection (b)( 1 )(B) instructs the Board to 

52 
establish regulations that bar issuers and networks from "inhibit[ing] the ability of any 

person who accepts debit cards for payments to direct the routing of electronic debit 

transactions for processing over any payment card network that may process such 

transactions." § 1693o-2(b)(l)(B). This sister provision to subsection (b)(l)(A) makes 

sense only if merchants have a choice between multiple networks. It would defY all logic 

for Congress to safeguard merchants' ability to route transactions over the networks of 

their choosing while at the same time leaving it up to the Board to decide whether issuers 

give merchants any choice in the first place. See Greenlaw v. United States, 554 U.S. 

23 7, 251 (2008) ("We resist attributing to Congress an intention to render a statute so 

internally inconsistent."); Griffin v. Oceanic Contractors, Inc., 458 U.S. 564, 575 (1982) 

("It is true that interpretations of a statute which would produce absurd results are to be 

avoided if alternative interpretations consistent with the legislative purpose are 

available."). Even the Board has recognized that its interpretation of subsection (b)( 1 )(A) 

limits the effectiveness of subsection (b)(l)(B) under the Durbin Amendment.41 

The Board further defends its network non-exclusivity regulation by pointing out 

that it is not "the most aggressively pro-merchant position" that the Board could have 

taken. Def.'s Reply at 27. The Board obviously misses the point! Where a court 

concludes that a statute is unambiguous, an agency's interpretation must be rejected if it 

is inconsistent with clearly expressed legislative intent. See Chevron, 467 U.S. at 842-

43; Vill. of Barrington, 636 F.3d at 659-60. It is not about whether the rule favors 

41 See 75 Fed. Reg. at 81,749-50 ("[T]he Board notes that Alternative A could limit the 

effectiveness of the separate prohibition on merchant routing restrictions under[§ 1693o2(b )(1 )(B)]"). 

53 
merchants or issuers; rather, it is about whether the rule implements Congress's will. 

And Congress's use of clear, defined language in the network non-exclusivity and routing 

provisions leaves no ambiguity or statutory gap for the agency to fill. See United States 

v. Home Concrete & Supply, LLC, 132 S. Ct. 1836, 1843 (20 12) ("Chevron and later 

cases find in unambiguous language a clear sign that Congress did not delegate gapfilling authority to an agency[.]"). 

Lastly, the Board noted that its two-networks-per-card approach "minimiz[es] the 

compliance burden on institutions" and "present[ s] less logistical burden on the payment 

system overall as it would require little if any re-programming of routing logic" than 

would a rule requiring two networks for each payment type. 76 Fed. Reg. at 43,447. 

That might be the case, but the law does not impose those burdens. In fact, the Durbin 

Amendment does not specify how the Board should go about achieving the statute's 

requirement. It was possible for the Board to implement the law without requiring brand 

new networks be added to each card. As explained during the comment period on the 

NPRM, the Board could have guaranteed "multiple routing options for every transaction 

by barring the dominant networks' anti-competitive rules to allow PIN-only networks to 

process signature transactions, and vice versa." Pl.'s Mem. at 51.42 In other words, the 

Board could have required networks to allow cross-routing of signature and PIN 

42 See, e.g., Adam J. Levitin, Comments in Response to Notice of Proposed Rulemaking 

on Debit Card Interchange Fees and Routing at 2-3 (Feb. 22, 2011) ("I would suggest 

that the Board also be explicit in permitting PIN debit networks to process signature-debit 

transactions as long as the merchant and/or network is willing to assume the chargeback 

risk . . . . Restricting limitations on cross-routing on debit cards between PIN and 

signature debit networks would enhance the competition among networks for processing 

transactions, which is precisely the goal of the Durbin Interchange Amendment."). 

54 
transactions, thereby ensuring that each debit card had multiple unaffiliated dual message 

network options on which every type of debit transaction could be processed. The Board 

chose instead to adopt a different approach-one that, unfortunately, is inconsistent with 

the statute. The final network non-exclusivity regulation therefore cannot stand under 

Chevron step one. See Catawba Cnty., 571 F.3d at 35. 

IV. The Appropriate Remedy Is Vacatur and Remand, Staying Vacatur. 

The Court concludes that the proper remedy here is to remand to the Board with 

instructions to vacate the Board's interchange transaction fee (12 C.F.R. § 235.3(b)) and 

network non-exclusivity (12 C.F.R. § 235.7(a)(2)) regulations. See 5 U.S.C. § 706(2) 

(directing that a court "shall ... set aside agency action ... found to be arbitrary, 

capricious ... or otherwise not in accordance with law."). Although I recognize that 

vacatur is not required by our Circuit, Advocates for Highway & Auto Safety v. Fed. 

Motor Carrier Safety Admin., 429 F .3d 1136, 1151 (D.C. Cir. 2005), I conclude that both 

factors to be considered when deciding whether to vacate-(1) "the seriousness of the 

[regulation's] deficiencies" and (2) "the disruptive consequences of an interim change 

that may itself be changed," Allied-Signal, Inc. v. U.S. Nuclear Regulatory Comm 'n, 988 

F.2d 146, 150-51 (D.C. Cir. 1993) (citation omitted)--weigh in favor ofvacating the 

specified regulations before remanding to the Board. 

First, the interchange transaction fee and network non-exclusivity regulations are 

fundamentally deficient. It appears that the Board completely misunderstood the Durbin 

Amendment's statutory directive and interpreted the law in ways that were clearly 

foreclosed by Congress. Because "[t]he Court cannot be sure that the agency will 

55 
interpret the statute in the same way and arrive at the same conclusion after further 

review," Int'l Swaps & Derivatives Ass 'n v. US. Commodity Futures Trading Comm 'n, 

No. 11-2146, 2012 WL 4466311, at *25 (D.D.C. Sept. 28, 2012), let alone whether, "on 

further judicial review, this or a similar Final Rule will withstand challenge under the 

APA," Humane Soc'y of US. v. Kempthorne, 579 F. Supp. 2d 7, 21 (D.D.C. 2008), this 

factor weighs heavily in favor of vacatur. 

Second, any disruptive effect of vacatur can be curtailed by a stay. This Court is 

mindful that interchange and network fees are critical components of the debit card 

system, and that the Board's Final Rule has been in effect since October 1, 2011, such 

that regulated interests have already made extensive commitments in reliance on it. 43 But 

in light of the seriously deficient nature of the regulations at issue, and the fact that the 

Board must develop entirely new rules to correct these errors, remand without vacatur 

would be inappropriate here. Compare Fox Television Stations, Inc. v. FCC, 280 F.3d 

1027, 1048 (D.C. Cir. 2002) (vacatur appropriate if rule is "irredeemable"), with 

WorldCom, Inc. v. FCC, 288 F.3d 429, 434 (D.C. Cir. 2002) (where there is a "non-trivial 

likelihood" that agency could justify rule on remand, vacatur is not necessary). I will 

stay vacatur, however, to provide the Board an opportunity to replace the invalid portions 

43 See Ronald M. Levin, "Vacation" at Sea: Judicial Remedies and Equitable Discretion 

in Administrative Law, 53 Duke L.J. 291, 300 (2003) ("Frequently, when a rule is held 

invalid after it has already gone into effect, private citizens will already have arranged 

their expectations around it. Companies may have entered into contracts, made capital 

investments, and shifted business operations in light of the rule."); MCI Telecomms. 

Corp. v. FCC, 143 F.3d 606, 609 (D.C. Cir. 1998) ("Here, vacating the order would leave 

payphone service providers all but uncompensated for coinless calls made from their 

payphones, and disrupt the business plans they have made on the basis of their 

expectation of compensation."). 

56 
of the Final Rule. In so doing, I can prevent the Board from adopting similar regulations 

while at the same time avoid the disruption of vacating the entire regime. See Anacostia 

Riverkeeper, Inc. v. Jackson, 713 F. Supp. 2d 50, 55 (D.D.C. 2010) (although pollution 

limits promulgated by EPA were inconsistent with Clean Water Act and thus invalid, 

vacatur stayed pending limits' revision because "neither the Court, nor the parties, wants 

the ... waters at issue in this action to go without pollutant limits while EPA develops 

new pollutant limits, which will obviously take some time"). 

To properly effect the stay of vacatur, two issues remain: (1) the appropriate 

length of the stay; and (2) whether current standards should remain in place until they are 

replaced by valid regulations or the Board should develop interim standards sufficient to 

allow the Court to lift the stay. See, e.g., Friends of the Earth, Inc. v. EPA, 446 F.3d 140, 

148 (D.C. Cir. 2006); Cement Kiln Recycling Coal. v. EPA, 255 F.3d 855, 872 (D.C. Cir. 

2001); Columbia Falls Aluminum Co. v. EPA, 139 F.3d 914, 924 (D.C. Cir. 1998); 

Anacostia Riverkeeper, 713 F. Supp. 2d at 52-55. Because the parties failed to address 

the proper remedy in their motions, the Court will invite supplemental briefing on these 

issues, keeping in mind that I am inclined toward a stay of vacatur "for months, not 

years," Natural Res. Def Council v. EPA, 489 F.3d 1250, 1265 (D.C. Cir. 2007) (Rogers, 

J., concurring in part and dissenting in part) (citations omitted). 

CONCLUSION 

For the foregoing reasons, the Court GRANTS plaintiffs' Motion for Summary 

Judgment and DENIES defendant's Cross-Motion for Summary Judgment. Accordingly, 

the Court will vacate the interchange transaction fee (12 C.F.R. § 235.3(b)) and network 

57 
non-exclusivity (12 C.F.R. § 235.7(a)(2)) regulations, staying vacatur until further Order 

of this Court, and will remand to the Board for further proceedings consistent with this 

Memorandum Opinion. An appropriate order shall follow.
