MEMORANDUM OPINION AND ORDER

MATTHEW F. KENNELLY, District Judge: 

 Continental Air Transport, which operates a van shuttle service in Chicago, has 

sued the United States under 26 U.S.C. § 7422, alleging that it is entitled to a refund for 

taxes and penalties that it says the Internal Revenue Service wrongfully assessed for its 

gasoline usage. Continental has moved for summary judgment on its claims. The 

government has conceded the claim on penalties it assessed against Continental but 

has cross-moved for partial summary judgment on Continental's refund claim. For the 

reasons stated below, the Court grants Continental's motion in part and denies it in part 

and denies the government's motion. 

Background 

 Continental is a transportation services company that ferries passengers 

primarily between downtown Chicago and the city's Midway and O'Hare airports under 

the name "Airport Express." It has modified its fifteen-passenger vans to include an 

aisle between seats and a luggage storage area, thus allowing up to ten passengers 
2

and their luggage. The company runs its vans along specified "routes," some of them 

color-coded. The Red Route from O'Hare, for example, has automatic stops at the 

Chicago Hilton and Palmer House hotels twice every hour, with scheduled stops at 

other nearby hotels and landmarks (such as Union Station) that occur only by 

reservation. See Pl.'s Ex. A-2 at 1. A traveler can make a reservation by phone, online, 

or through a hotel, choosing scheduled a pick-up time at a specific location. 

 In an affidavit, John McCarthy, Continental's president and part-owner, says 

there are three exceptions to the company's route / scheduled pick-up scheme. First, if 

a passenger requests a pick-up at a location not on one of Continental's routes, but 

near one of its automatic-stop hotels, Continental will pick up that passenger while 

traveling one of its assigned routes. McCarthy estimated such stops account for eight 

to eleven percent of passengers picked up along Continental's scheduled routes. 

Second, a group of six to ten passengers requiring transportation from a single hotel to 

one airport may get its own Continental van, which travels directly from the hotel to the 

airport without other stops. McCarthy said these trips "accounted for less than 1% of 

the total passengers transported" during the time period at issue here. Pl.'s Ex. A ¶ 38. 

Finally, Continental sometimes will shuttle a "small group between a Downtown hotel 

and some other location, like a sports or music venue." Id. ¶ 39. McCarthy estimated 

that such trips amounted to "less than .7%" of Continental's total passengers. Id.

 Like anyone who buys gasoline, Continental pays federal excise taxes when it 

fills up the tanks in its vans. At the end of each quarter in 2008 and 2009, and after the 

first quarter of 2010, Continental filed refund claims with the IRS for the excise tax it 

paid. For each quarter in 2008 and 2009, the IRS paid the refund, but it began an audit 
3

of Continental in April 2010 for the period from 2008 through the first quarter of 2010. 

The IRS determined that Continental's vehicles did not qualify as "automobile buses," a 

prerequisite to receiving a gasoline excise tax refund from the government under 

26 U.S.C. § 6421(b). The IRS report's conclusion stated: "Taxpayer is not entitled to 

the refund of excise taxes paid for gasoline fuel. The company does not use 

buses . . . ." Pl.'s Ex. D-2 at IRS000742. It sent Continental a letter assessing excise 

taxes of $152,305.81 and a penalty of $279,861.16 under 26 U.S.C. § 6675(a), which 

permits a double penalty for "excessive" tax claims. 

 After filing an unsuccessful protest with the IRS, Continental in September 2011 

paid the taxes and penalties assessed for the quarter ending March 31, 2009: 

$14,403.66 in gasoline taxes and $28,807.32 in penalties. It then filed an amended 

excise tax return for that quarter, seeking a refund of the taxes and penalties it had just 

paid. A month later, in October 2011, the IRS sent Continental a check for $25,426.54; 

the parties disagree on whether it was a partial refund of the penalties Continental had 

paid. In November 2011, the IRS sent Continental a "Notice of Case Resolution" 

document stating that Continental owed no excise tax for the periods in question, save 

for the periods ending March 31, 2009 and March 31, 2010. Finally, in December 2011, 

the IRS told Continental it was disallowing its refund claim of $432,166.97 for the 

periods in question. 

Discussion 

A party is entitled to summary judgment if it "shows that there is no genuine 

dispute as to any material fact and [it] is entitled to judgment as a matter of law." Fed. 

R. Civ. P. 56(a). On cross motions for summary judgment, the court assesses whether 
4

each movant has satisfied the requirements of Rule 56. See Cont'l Cas. Co. v. Nw. 

Nat'l Ins. Co., 427 F.3d 1038, 1041 (7th Cir. 2005). "As with any summary judgment 

motion, we review cross-motions for summary judgment construing all facts, and 

drawing all reasonable inferences from those facts, in favor of the non-moving party." 

Laskin v. Siegel, 728 F.3d 731, 734 (7th Cir. 2013) (internal quotation marks omitted). 

 The Internal Revenue Code includes a subsection directing the IRS to make 

refunds to certain entities and individuals who pay excise taxes on gasoline, under the 

heading "Intercity, local, or school buses": 

[I]f gasoline is used in an automobile bus while engaged 

in . . . furnishing (for compensation) passenger land 

transportation available to the general public, . . . the 

Secretary shall pay (without interest) to the ultimate 

purchaser of such gasoline an amount equal to the product 

of the number of gallons of gasoline so used multiplied by 

the rate at which tax was imposed on such gasoline by 

section 4081. 

26 U.S.C. § 6421(b)(1)(A). The next subsection states that the refund requirement does 

not apply with regard to "gasoline used in any automobile bus while engaged in 

furnishing transportation which is not scheduled and not along regular routes unless the 

seating capacity of such bus is at least 20 adults (not including the driver)." Id.

§ 6421(b)(2). The statute does not define "automobile bus" or "regular routes." 

Nonetheless, the definition of both terms is central to this dispute. If Continental is not 

an automobile bus operator, or does not operate its vehicles on regular routes, both 

parties agree it is not entitled to the refund. The Court will address each term in turn.1

 

1

 The government has expressly conceded one of Continental's claims: that it is entitled 

to the remainder of the refund it claimed the government owed after erroneously 

imposing penalties under 26 U.S.C. § 6675. Continental is therefore entitled to 

summary judgment on its claim of $3,380.78, plus statutory interest.

A. "Automobile bus"

 Continental argues that its vans should be considered "automobile buses" for 

purposes of section 6421, relying on what it calls "established IRS authority" and 

legislative history, as well as the sole case that has construed the term thus far. See 

Pl.'s Mem. at 4. The company points to a 1970 IRS ruling stating that a "modified 

passenger sedan or station wagon" possessed the functions of a bus and argues a van 

is even more like a bus than either of those vehicles. See id. (citing Rev. Rul. 70-9, 

1970-1 C.B. 216, 1970 WL 21126). Continental also cites a 2010 letter from thenTreasury Secretary Timothy Geithner to various members of Congress, informing them 

that the IRS was "developing guidance" that would not exclude vans from the class of 

vehicles qualifying for the gasoline excise tax exemption. See id. at 8–9 (citing Letter 

from Timothy F. Geithner, Sec. of the Treasury, to Sen. Kirsten Gillibrand (June 2, 

2010), available at 2010 WL 2481970). (Whether this guidance was ever issued is 

unsaid.) Continental also cites a 1977 Senate report, from which it draws an inference 

that the Senate assumed vans were covered under the gas tax exemption. Finally, 

Continental argues that the United States Tax Court explicitly declined to rule on 

whether vans counted as buses under the statute when it addressed the "automobile 

bus" term in 2006, as did Eleventh Circuit on appeal. See Med. Transp. Mgmt. Corp. v. 

Comm'r, 127 T.C. 96 (2006), aff'd, 506 F.3d 1364 (11th Cir. 2007). 

 The government nonetheless bases its argument on the Tax Court's decision in 

Medical Transport. Def.'s Mem. at 4. It contends that the Tax Court's reliance on the 

word "omnibus" to guide its construction of "automobile bus" supports the notion that 

vans are not buses. The Tax Court's cited definition of "omnibus," for which "bus" is an 
6

abbreviation, included the term "designed to carry a comparatively large number of 

passengers." Med. Transp., 127 T.C. at 102. The government proceeds to use a 

dictionary to define "large" as "[o]f greater than average size," and concludes that 

because Continental has modified fifteen-passenger vans to carry ten people, the 

vehicles' capacity is not "greater than average" or "comparatively large." Def.'s Mem. at 

5 (quoting American Heritage Dictionary (2d ed. 1982) (no page number provided)). 

 To begin with the statute itself, section 6421 suggests no definition of 

"automobile bus," and the term is not—or is no longer—used in everyday parlance. The 

Eleventh Circuit's opinion on this question discussed a possible reason for the inclusion 

of the modifier "automobile" for "bus": "When Congress amended section 6421(b) in 

1978, Congress had long used the adjective 'automobile' in tax statutes in reference to 

motor-driven vehicles." Med. Transp., 506 F.3d at 1368 (citing examples). The court 

reasoned that "automobile" is simply a modifier for "bus," meaning a bus with its own 

power source; it used a dictionary to define "bus" as "a large motor vehicle designed to 

carry passengers." Id. (citing Merriam–Webster Coll. Dictionary 154 (10th ed. 1996)). 

 The Court agrees with the Eleventh Circuit's definition of the term, which accords 

with what a typical person would consider a "bus." Although the Eleventh Circuit "le[ft] 

for another day the question whether a van or other vehicle can be classified as a bus," 

id. at 1369, there is no issue of material fact about whether Continental's vans logically 

fit within that court's definition of the term. The vans are large—certainly larger than 

typical four-door passenger cars, vans, or SUVs, from the photos Continental has 

provided—and they are designed to carry passengers; that is their primary function. 

They have side-opening doors like a bus (although not the accordion-style doors often 
7

seen on city and school buses), and they have been modified so that there are aisles for 

passenger entry and exit. Although the vans obviously do not resemble typical buses, 

they are more bus-like than other passenger vehicles, including the sedans at issue in 

Medical Transport. 

 The government's argument on this point is unavailing. It latches onto the phrase 

"greater than average" from its definition of the term "large," arguing that because 

Continental modified fifteen-passenger vehicles to fit ten people, its vans are not 

"relatively large." One can infer from this that unmodified fifteen-passenger vans fit the 

government's interpretation, but not ten-passenger vans. The government provides no 

explanation of why the difference matters for its definition of "large." Would this mean, 

for example, that an eight-passenger van qualifies for the tax refund, so long as it is not 

modified to fit five passengers? In short, there is no limiting principle for the 

government's interpretation. 

 In sum, the Court agrees with Continental that no reasonable fact finder could 

find that its vans are not automobile buses for purposes of 26 U.S.C. § 6421(b). 

B. "Regular routes"

 As discussed above, section 6421(b)(2) precludes an excise tax refund with 

regard to gasoline used in an "automobile bus" providing transportation that "is not 

scheduled and not along regular routes." The parties dispute whether Continental's van 

service is along regular routes. Continental argues that "well established common 

carrier law" shows that its routes are regular, citing a 1948 district court case and a 

1995 decision of the Surface Transportation Board that appeared to examine the 

"essential character of the operations at issue" in deciding whether to deem a service 
8

"regular-route." Pl.'s Mem. at 11 (citing State of New Jersey—Petition for Declaratory 

Order—Scope of Intrastate Passenger Authority, S.T.B., 1995 WL 756133 (Dec. 13, 

1995)). Continental further contends that the established routes and automatic stops of 

its vans indicate that they are "consistently running regularly scheduled routes between 

two fixed locations: an airport and Downtown Chicago." Id. at 13. It admits that the 

stops along those routes sometimes varied based on passenger needs, although it 

contrasted its system with that in Medical Transport, where sedans were assigned 

based on passengers' individual destinations. Continental also concedes that it 

provided "discrete trips" to non-airport locations. Id. at 14. It argues, however, that 

section 6421(b)(2) should not be read as inflexible, and it contends that vehicles 

performing these services were reassigned to a regular route directly afterward. 

 The government responds by again looking to the Tax Court's decision in 

Medical Transport, particularly a passage citing a 1977 Senate report referring to 

regular-route service "such as is provided by local transit systems or an intercity bus 

operation." Def.'s Mem. at 6 (citing Med. Transp., 127 T.C. at 104 (citing S. Rep. No. 

95-529, at 55 (1977))). The government then analyzes Continental's van operations, 

observing that unlike a city bus, a Continental van may deviate from its route once it is 

full of passengers and proceed directly to an airport, whereas city buses will continue on 

the given route and discharge passengers while picking up others. It also argues that 

some of Continental's business is not route-based service, citing Continental's practice 

of picking up passengers at non-scheduled stops that are near scheduled stops and 

providing charter service or single-group vans directly between one hotel and an airport 

or other locations. 
9

 Although few would disagree that Continental's services are not exactly like what 

many city buses do,2

 that is not the end of the matter. The government focuses on the 

city bus as a regular-route operation cited in the Tax Court's opinion, but the city bus 

example the case cites is just that—an example, not a definition. In fact, Continental's 

vans are easily distinguished from the sedan service at issue in Medical Transport. In 

that case, there were "no published timetables," with schedules "prepared the night 

before the travel day." 127 T.C. at 106. "[T]here was no way of knowing, short of 

asking the driver, whether the vehicle followed the same or similar routes as the 

corresponding run on a subsequent day or week." Id. at 106–07. Furthermore, "no two 

manifests contained substantially similar patterns of destinations traveled or 

pickup/dropoff times." Id. at 107. In contrast, Continental's service has set, published 

routes, each with a different name focusing on transit between one airport and a select 

area of downtown Chicago. Although the vans do not stop at each hotel listed on its 

schedule on every trip, they do have mandatory stops, indicating regularity. The 

government argues that a full van will dispense with its other stops and proceed to its 

assigned airport and thus does not have a regular route. However, it is because of 

pickups along its regular route that the van fills to capacity; that does not mean that the 

van lacks regular-route service. The airport, after all, is part of the van's route. It could 

be said that express city buses, which operate between a cluster of stops in one area 

and then proceed downtown without stopping again, do the same thing when they reach 

capacity. The Court therefore agrees with Continental that there is no genuine issue of 

 

2

 Actually the differences are not as stark as the government argues. It is not unheard 

of, for example, for a city bus that is running a regular route but is completely full of 

passengers to skip stops, even where potential passengers might be waiting, if no 

passenger on the full bus has signaled to get off. 
10

material fact over whether these scheduled, route-based van services are "along regular 

routes" for purposes of 26 U.S.C. § 6421(b)(2). 

 On the other hand, the government is correct to point out that not all of 

Continental's van service can be considered "regular route" service. As McCarthy, 

Continental's president, says in his affidavit, the company sometimes provides what 

might be called charter services—driving a group from a hotel to "some other location, 

like a sports or music venue." Pl.'s Ex. A ¶ 39. Although these trips "accounted for less 

than .7% of the total passengers transported by Continentals vehicles," id., they cannot 

be considered as following "regular routes." Similarly, Continental's vans sometimes 

pick up a large group from a single hotel and go straight to an airport, though this 

accounts for "less than 1%" of all company passengers according to McCarthy. Id.

¶ 38. Finally, Continental's vans sometimes deviate from their regular routes to do 

pickups at non-scheduled locations, thus adding stops based on individual passenger 

needs. McCarthy explains the percentage of passengers requiring such services 

differently, saying they account for "8% to 11% of all passengers who were picked up 

along one of the scheduled routes," id. ¶ 37, but not describing their proportion of 

Continental's total number of passengers. And none of these figures describes what 

proportion of bus runs is involved, which presumably would be the more significant 

figure for purposes of gasoline consumption. 

 In short, although no reasonable fact finder could find that the overwhelming 

proportion of Continental's van business consists of anything but regular-route service, 

some small amount is not. The exact percentage is unclear. Although Continental 

argues that the gasoline tax refund statute should not be held to be "inflexible," the 
11

statute clearly states that a refund is permitted only with respect to gasoline used for 

regular-route service. See 26 U.S.C. § 6421(b)(2) (stating that the statute "shall not 

apply in respect of gasoline used in any automobile bus while engaged in furnishing 

transportation which is not scheduled and not along regular routes"). 

 The government advanced what it called a separate argument in its initial brief 

that Continental failed to submit sufficient records with its claims, adding that 

Continental's vans did not always perform in ways entitling the company to a gas tax 

refund. In the government's reply, it essentially contended that Continental had not 

provided evidence detailing exactly how much gasoline its vans consumed when 

performing its non-scheduled, non-regular route services. Continental notes that the 

IRS's examiners had previously found that the company has regular routes, and it says 

that it should not be encouraged to "engage in absurd behavior" like making superfluous 

stops to qualify for the refund. Pl.'s Repl. at 6. But Continental nonetheless concedes 

that it provides some non-scheduled, non-route-based services. Given that admission, 

the Court concludes that there is insufficient evidence in the record at this point to 

determine the precise scope of the refund. This is not, however, a reason to deny 

summary judgment altogether to Continental, given the Court's other conclusions 

discussed above. 

 In sum, the Court concludes that Continental is entitled to summary judgment on 

the issue of liability. No reasonable fact finder could disagree that its vans are 

automobile buses, and that the overwhelming majority of its routes should be 

considered regular for purposes of 26 U.S.C. § 6432. There is not enough evidence, 

however, to make a summary judgment ruling one way or another on the question of 
12

what, if anything, Continental is entitled to receive as a refund from the government—

aside from the $3,380.78 in erroneously imposed penalties conceded by the 

government. See n.1 supra. The Court therefore determines that further proceedings 

on the appropriate amount of damages in this case will be necessary. 

Conclusion

 For the foregoing reasons, the Court grants Continental's motion for summary 

judgment in part [docket no. 31] and denies the government's cross-motion for partial 

summary judgment [docket no. 35]. The parties are directed to confer regarding what 

further proceedings will be necessary to bring the case to disposition. A joint status 

report including each side's position in this regard is to be filed by February 14, 2014. 

The case is set for a telephone status hearing on February 19, 2014 at 9:00 a.m.
