CIVIL ACTION NO. 7:19-cv-00269

ORDER AND OPINION
The Court now considers Plaintiffs’ motion to strike Edward Rock’s expert report and
exclude his testimony,1 Defendants’ motion to exclude the testimony of Thomas Z. Lys and
Coleman Bazelon, and alternative motion,2 responses,3 replies,4 and exhibits.
I.

BACKGROUND AND REMAINING PRE-TRIAL ISSUES
In ruling on the parties’ motions for summary judgment, the Court found liability for—

inter alia—Defendants’ operation of Cricket in competition with Plaintiff Partnerships and
Defendants’ decision to retain spectrum licenses to extract value from the Partnerships in
abrogation of their contractual and fiduciary duties.5 Now, the parties have moved to strike certain
of each other’s expert reports and exclude those experts from trial.

LEGAL STANDARD FOR EXPERT OPINION ADMISSIBILITY
“[T]he Federal Rules of Evidence control the admission of expert testimony.”6 Rule 702

provides:
A witness who is qualified as an expert by knowledge, skill, experience, training,
or education may testify in the form of an opinion or otherwise if:
(a) the expert’s scientific, technical, or other specialized knowledge will
help the trier of fact to understand the evidence or to determine a fact in
issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of
the case.7
“Expert testimony which does not relate to any issue in the case is not relevant and, ergo, nonhelpful. Similarly, low probative value, or a total lack of it, will render proposed expert testimony
unhelpful and, therefore, inadmissible under Federal Rule of Evidence 702.”8 The Court
scrutinizes proposed expert testimony more searchingly than lay witness testimony for its
pertinency and potential prejudice.9
There is a relevancy problem where an expert opinion is primarily legal in nature because
“[e]xperts cannot render conclusions of law or provide opinions on legal issues.”10 In a jury trial,
the judge determines the applicable law, so legal opinions are not helpful to the jury as trier of fact.
Furthermore, “the trial judge ought to insist that a proffered expert bring to the jury more than the
lawyers can offer in argument.”11

Once testimony is deemed relevant, the reliability of the expert’s methodology becomes
the touchstone. The Daubert test is a flexible one,12 and “under Daubert, any step that renders the
analysis unreliable renders the expert’s testimony inadmissible. This is true whether the step
completely changes a reliable methodology or merely misapplies that methodology.”13
To test reliability, the Court assesses the intellectual rigor of the proposed expert
testimony,14 which must be validated by an independent and objective source beyond the expert’s
assurances,15 and the Court “should ensure that the [expert] opinion comports with applicable
professional standards outside the courtroom and that it will have a reliable basis in the knowledge
and experience of [the] discipline.”16 However, an expert report or opinion need not be in lockstep
with the relevant discipline’s prevailing view in order to be admissible.17 “Certain more specific
factors, such as testing, peer review, error rates, and ‘acceptability’ in the relevant scientific
community . . . might prove helpful in determining the reliability of a particular scientific ‘theory
or technique.’”18 Reliance on studies that do not support a contention, cherry-picked data, or a
dubious methodology may be grounds to reject expert testimony.19
The Court’s task at this stage is gatekeeping, not premature factfinding. “As a general rule,
questions relating to the bases and sources of an expert’s opinion affect the weight to be assigned

that opinion rather than its admissibility and should be left for the jury’s consideration.”20 Indeed,
the Fifth Circuit has cautioned against transforming a motion to exclude an expert into a trial on
the merits, because the factfinder may be entitled to accept or reject an expert’s testimony including
by judging whether the predicate facts on which an expert relied are accurate.21 In short, experts
may rely on disputed facts, but not unsubstantiated assertions. Cross-examination and presentation
of competing evidence, rather than exclusion for inadmissibility, are the traditionally favored ways
to challenge an expert opinion.22 “It is the role of the adversarial system, not the court, to highlight
weak evidence.”23

APPLICATION
Defendants move to exclude testimony of Thomas Lys and parts of the testimony of

Coleman Bazelon. Defendants allege that Dr. Bazelon’s reply report raises new opinions and
should be stricken, or alternatively, they should be granted leave to designate a reply expert.
Plaintiffs move to strike the rebuttal report and exclude trial testimony of Edward Rock as a legal
opinion.
A. Coleman Bazelon
Plaintiffs’ expert Coleman Bazelon is an economic consultant specializing in
telecommunications and intellectual property. He consults on regulation, wireless license auctions,

competition policy, patent infringement, and asset valuation.24 Here, he includes his opinions on
cannibalization of Partnership customers. Cannibalization occurs when there is competition among
affiliates; when an existing operator (in this case, AT&T) launches a new brand (in this case,
Cricket), it predicts how many customers will leave the legacy brand for the new one.25 Those
customers are said to be “cannibalized,” while new customers that the legacy brand would not
have picked up otherwise are “additive.”26
Defendants argue that Dr. Bazelon’s cannibalization figures rely on invalid assumptions
and that he changes his cannibalization methodology between his initial report and his reply report.
They also argue that he uses very late ex post evidence and unreliably extrapolates from a single
data point to value the relevant spectrum licenses.
1. Cannibalization
Dr. Bazelon’s cannibalization methodology is produced in his initial report as a formula.27
In words, it calculates cannibalized subscriber additions in a given market in a given quarter as a
function of Cricket’s gross additions in south Texas times the proportion of the south Texas market
in the given partnership, minus the estimated gross additions for a hypothetical, independent
Cricket (the “baseline”). The resulting figure—how many subscriber additions are a result of
AT&T—is adjusted for diversion and churn.
Defendants challenge28 Dr. Bazelon’s use of a regression analysis to construct data for
certain periods, including January and February of 2014 (before the merger) and periods in 2014
where the data is unusually low.29 But the rationale for the regression analysis is clear: the de

minimus data from January and February 2014 come from AT&T’s legacy separate pre-paid
service, Aio.30 Pre-merger (i.e., non-AT&T) Cricket was larger than that.
Dr. Bazelon uses “2015 post-acquisition data to estimate the 2014 Cricket but-for baseline[,
which] incorporates any increases in gross additions that Cricket would have experienced from the
AT&T acquisition.”31 On this issue, Plaintiffs’ calculation of damages is the difference between
the baseline and the actual. But for January and February 2014, the baseline and actual have yet to
diverge because the acquisition has not happened yet. Use of regression analysis to project
unusually low data in other periods (after the merger) will be addressed below.
In his reply report, Dr. Bazelon changes several relevant items, which Defendants now
challenge as unfounded and deserving of another reply report. He (1) opts for a monthly analysis
instead of a quarterly analysis, (2) zeros out negative cannibalization, (3) accepts unusually low
post-merger data that he previously rejected in favor of his own regression results, and (4) creates
a Covid-19 adjustment for the 2020 and 2021 baselines.
A reply report is subject to the same reliability standards. Furthermore, the Court looks to
four factors in deciding whether to exclude expert testimony as untimely: “(1) the explanation for
the failure to produce the report earlier; (2) the importance of the testimony; (3) potential prejudice
in allowing the testimony; and (4) the availability of a continuance to cure such prejudice.”32 For
reasons that will become clear, the Court will not exclude Dr. Bazelon’s report for timeliness.
Why did the reply report switch to a monthly analysis? Defendants assert that Dr. Bazelon
“changed his methodology to a monthly view and—without explanation or any basis for doing
so—simply excluded any months where negative cannibalization resulted from his calculations.”33

Defendants know full well why the initial report looks at quarters and the reply report looks at
months; they did not produce the more granular, responsive documents until after their own experts
used them.34 While Plaintiffs could dial it down a bit on the ad hominem attacks on counsel,35 the
Court is satisfied that the changes in the reply report were necessitated by Defendants’ lack of
production.
Defendants did not produce the monthly data that covered post-2016 periods until June 23,
2022—after Plaintiff’s expert designation deadline, but just one day after Defendant’s expert
designation deadline.36 Defendants have a duty to timely supplement production when it finds
responsive documents37 even if Plaintiffs do not complain of incompleteness or file a motion to
compel. Plaintiffs do not know what they do not have. In a case this old, the Court is highly
skeptical that the responsive documents were serendipitously found between May 16th and June
23rd.38 The Court will not exclude the reply report for timeliness issues, nor will it grant
Defendants’ motion to designate a new expert since its expert had a first look at the new data that
inspired the reply report. Plaintiffs have sufficiently explained the need for Dr. Bazelon’s reply
report, and there is no prejudice in Plaintiffs’ experts using the same data used by Defendants’
experts. Defendants’ motion for leave is therefore DENIED.
In the reply report, Dr. Bazelon collapses all “negative cannibalization” to zero.39 Negative
cannibalization is not the Partnerships taking back Cricket customers.40 It is when AT&T’s Cricket
underperformed compared to the gross additions Dr. Bazelon projected for hypothetical Cricket

not owned by AT&T.41 Dr. Bazelon’s choice to shift from a “conservative” approach in the initial
report (given the incomplete data) to what he considers a more accurate approach in the reply
report may be fair game on cross examination. But that choice does not make his whole
cannibalization methodology unreliable.
The apparent inconsistency in Dr. Bazelon’s acquiescence on the unusually low postmerger data but continued use of regression data for pre-merger gross adds is explained. In
analyzing the initial data, he “could not distinguish between a transition where there may have
been a ramp up in gross additions and data errors. However, the data that Ms. Taylor [Defendants’
expert] uses in her analysis . . . includes these apparently anomalous data points [so Dr. Bazelon]
incorporates these early months into [his] updated analysis.”42 In other words, since Defendants
doubled down on those figures, he decided to take them at their word. In contrast, the de minimus
data from January and February 2014 continues to need replacing, in his opinion.
Dr. Bazelon applies a Covid-19 adjustment to gross additions “to account for the depressed
level of gross additions” during 2020 and 2021.43 Defendants put forth a theory that this was an
outcome-oriented hack that Dr. Bazelon pulled off when he “found he had grossly overestimated
[Cricket] performance [and] needed a new and lower baseline to maintain or increase damages.”44
But if the baseline is meant to project hypothetical Cricket’s performance through 2021, then the
same market forces created by Covid-19 which effected real Cricket would effect the baseline. Dr.
Bazelon’s model takes this into account.

Case 7:19-cv-00269 Document 121 Filed on 04/04/23 in TXSD Page 9 of 14

Defendants point out that the report’s tables indicate several high individual p-values and
ask the Court to find the Covid-19 adjustment statistically insignificant.45 Dr. Bazelon explains
that to construct the Covid-19 adjustment, he “use[s] two dummies for the year 2020 and 2021 and
their interactions with the time trend and the quarter dummies. The F-stat[istic] shows that the
covariates are jointly significant.”46
An insignificant p-value would be problematic if Dr. Bazelon were running a t-test to
determine if Covid-19 caused the depressed year-over-year gross addition numbers. But that is not
what is going on here. Instead, the reason for this data is to project baseline gross addition numbers
for hypothetical Cricket that reflect the same market forces impacting real Cricket. For 2020 and
2021, real Cricket’s numbers are conspicuously lower. Conspicuousness does not equate to
statistical significance, but it does not need to. Even if Covid-19 is not the sole cause, there is no
reason to think that the global causes impacting real Cricket would not also impact hypothetical
Cricket.47 The report calls this the “COVID adjustment” since it correlates with 2020-2021 and
there is statistical significance on a quarter-over-quarter basis. But the adjustment’s validity does
not actually depend on isolating Covid-19 as the statistically significant reason for the lower
numbers.

case, . . . while the overall effect of these variables may be strongly statistically significant, each coefficient may not

2. Spectrum
Defendants argue that Dr. Bazelon’s valuation of the portion of the spectrum licenses in
the Partnerships’ service areas is unreliable because it relies on ex post FCC auction data from up
to nine years after AT&T’s license acquisitions and that it improperly extrapolates from a single
data point.48 Contrary to Defendants’ vigorous arguments, courts rarely establish hard rules that
certain methodologies are always unreliable and excludable. It matters what is being measured,
and why.
What does Dr. Bazelon measure with respect to the spectrum licenses? He does not give
an absolute valuation (i.e. the fair market price) for the licenses; he calculates the portion of the
overlapping license’s book value (i.e. the price AT&T paid) associated with the Partnerships’
service areas.49 So long as it is applied consistently—by using the same valuation metrics on both
sides of the Partnership boundary and apportioning the relative book value to each side—this
methodology does not require estimation of the license’s absolute price.50
While very late ex post auction data would likely be unreliable as to absolute value, its
reliability as to relative value is properly explained. A subsequent auction may be a bad measure
for absolute value because the market’s projection for that spectrum band’s use (and thereby, value
to an operator) might change dramatically over time. But the proportional share of a license’s
value as between two geographic areas is unlikely to change dramatically over time barring rapid
population swings.
Thus, Dr. Bazelon uses auction data to construct relative value indexes, which allow him
“to value one particular geography relative to another geography, without having to know the

48

Dkt. No. 87 at 44-49.
Dkt. No. 87-3 at 101-103, ¶¶ 135-137.
50
This consistency appears to have been implemented in Dr. Bazelon’s report. Dkt. No. 87-3 at 105, ¶ 141.
49

10 / 14

Case 7:19-cv-00269 Document 121 Filed on 04/04/23 in TXSD Page 11 of 14

absolute value of either.”51 The book value paid by AT&T will be plugged in as the absolute value
of the overlapping license, so the age of the auctions from which the relative value indexes are
developed does not render the methodology unreliable.
While Defendants assert several times that Dr. Bazelon relies on “a single transaction” or
“a single data point,” they do not cite to his report nor explain their claim.52 From the Court’s
review of the report, it appears that constructing the relative value indexes involves comparing
several licenses that envelop the same service area to triangulate the effected Partnerships.53
Auction data is used here to empirically capture data that effects spectrum pricing beyond
population alone. This methodology is necessary because—as Dr. Bazelon points out—
Defendants have attempted to have their cake and eat it too by (1) their appraiser, Duff & Phelps,
using extra-populational metrics such as income, terrain, and population density to arrive at a fair
value but (2) AT&T charging the Partnerships their allocated portion based on population alone.54
Dr. Bazelon’s use of empirical data here also highlights a difference between his testimony in this
case and his testimony in the Delaware case that Defendants would like to compare it to.55 There,
contrary to Defendants’ incorrect briefing,56 Dr. Bazelon was permitted to testify at trial, but the
weight of his testimony was discounted for relying on projections of absolute spectrum valuation
when examples of real market transactions were available.57 Here, Dr. Bazelon’s testimony makes
use of the real world market evidence that he was criticized for ignoring. For all of the
aforementioned reasons, Defendants’ motion is DENIED as to the Bazelon report.

B. Thomas Lys
Defendants argue that Dr. Lys’ report constitutes an improper legal conclusion, that his
analysis of the processes used by AT&T contains no particular skill, and that he improperly relies
on the Bazelon report.
First, “[a]n opinion is not automatically objectionable just because it embraces an ultimate
issue.”58 Defendants’ cited authorities stand for the proposition that expert opinions on what law
applies or how it should apply are improper. That is the Court’s domain. But there is nothing
improper about an expert arriving at a conclusion based on the facts analyzed and the law provided
by the Court. Dr. Lys’ report shows a meticulous effort to use only the interpretations of Delaware
law and the parties’ Partnership Agreements which have already been endorsed by the Court.
Since then, the Court has found in Plaintiff’s favor on many of these ultimate issues of
liability.59 Since the jury will be instructed consistent with that opinion anyway, there is nothing
improper about Dr. Lys’ dependance on those findings. Furthermore, finding liability is a threshold
issue for assessing damages—the job Dr. Lys was hired to do. If he did not think AT&T was liable
for underpaying the Partnerships, he would not quote an underpayment figure.
Second, the Court finds that Dr. Lys’ opinion is based on specialized knowledge and skills
that will be helpful to the jury. Two examples will suffice. The report provides an opinion on how
typical reseller mobile virtual network operator (MNVO) contracts function—including volume
minimums and maximums—and how AT&T’s use of Partnership networks at a reseller rate
differed from those contracts.60 Another example is his application of accounting standards to
AT&T’s expense offsetting as a form of compensation.61

Third, because Dr. Bazelon’s testimony is admissible, Dr. Lys’ reliance on it is not
improper. Defendants’ motion is DENIED as to the Lys report
C. Edward Rock
Finally, Professor Rock’s rebuttal report to Dr. Lys differs from the other reports in type,
not degree of reliability. It is a legal brief by a law professor and legal expert. It deals with
interpretation of Delaware law and interpretation of the parties’ contracts. These opinions attempt
to usurp the role of the Court and are easily excludable under Rule 702(a). The Court—not a
rebuttal witness—will ensure that Dr. Lys’ opinions comport with the correct legal standards.
Defendants cast Professor Rock’s opinion as one about the Partnerships’ organizational
design as opposed to an interpretation of the Partnership Agreements themselves.62 But it is clear
from reading Professor Rock’s report that his arguments against Dr. Lys’ organizational design
opinions are legal arguments based on the Agreements and Delaware law.63 These points can be
made by the lawyers.
Still, the Court identifies two topics in Professor Rock’s report with potential probative

that are not for the jury to decide. His rebuttal report is hereby STRICKEN, and his testimony
EXCLUDED.
IV.

CONCLUSION
Accordingly, the Court hereby GRANTS Plaintiffs’ motion and DENIES Defendants’

motions.
