        JUSTICE GUZMAN, joined by CHIEF JUSTICE HECHT and JUSTICE BUSBY, concurring and
dissenting.


       A jury found Carrizo Oil & Gas, Inc. breached a farmout agreement with Barrow-Shaver

Resources Co. by unreasonably withholding consent to an assignment of the agreement while

attempting to extract a $5 million consent-procurement fee. Disregarding the jury’s findings, the

Court holds the farmout agreement’s terms permitted Carrizo to do so. The Court’s construction of

the farmout agreement as allowing Carrizo to act unreasonably in withholding consent is analytically

flawed in several respects, but most notably in repudiating trade usage and custom as an aid to

contract interpretation. And though the Court embraces a construction of the contract that allows

Carrizo to “refuse consent for any reason, expressed or not, reasonable or not, legitimate or not, or
no reason at all,”1 it simultaneously shrinks from that holding by repeatedly asserting—contrary to

the jury’s findings—that Carrizo actually had valid reasons for withholding consent.

       In determining whether the farmout agreement’s consent-to-assign clause is qualified by

reasonableness, the threshold question is: what does the contract say? Only if the consent provision

is unqualified would we then consider whether reasonableness is either required by statute or other

law or implied as a matter of public policy. The Court muddles these analytical steps and,

consequently, misapplies case law regarding the latter two concepts in construing the farmout

agreement. The law applicable to each analytical step differs, but the Court consistently ignores the

distinctions in determining what the farmout agreement’s terms mean.

       I part company with the Court at the first analytical step—what the contract says. The point

of disagreement is not, as the Court suggests, whether reasonableness should be judicially imposed.

Here, the jury found reasonableness is baked into the contract language through trade custom and

usage, and the record bears evidence to support that finding. The Court categorically rejects

evidence that trade custom and usage informs the consent clause’s meaning on the basis that words

with ordinary meanings, like “consent”, are not amenable to any industry-specific usage. This is

wrong. “The normal effect of a usage on a written contract is to vary its meaning from the meaning

it would otherwise have,” so long as the usage has “such regularity of observance in a place,

vocation, or trade as to justify an expectation that it will be observed with respect to a particular

agreement.”2 Consulting trade custom and usage to interpret contract terms is a centuries-old

practice firmly rooted in our jurisprudence, recognized by learned treatises, and applicable to

commercial contracts nationwide, including in Texas.

         The Court’s rejection of trade-custom-and-usage evidence leads to an erroneous construction

of the farmout agreement, abrogates established contract-construction principles, and threatens to

unsettle industry expectations about what industry-specific contracts mean.3 The Court’s insistence

on characterizing the record contrary to the jury’s findings is equally alarming but ultimately proves

the industry expects industry players to act reasonably in multi-million dollar energy transactions.4

Because the Court’s analysis and construction of the farmout agreement is erroneous and

disconcerting, I respectfully dissent. I concur in the fraud judgment, however, because I would

arrive at the same judgment for different reasons.

                                                  I. Background

         The contract-construction issue in this case involves a consent-to-assign clause in a farmout

agreement between Barrow-Shaver and Carrizo, two oil and gas companies. Carrizo owned

leasehold interests for depths below 2,500 feet of the 22,000-acre Parkey Ranch, which were

acquired from Pan American Operating, Inc. (the Parkey lease). PanAmerican, in turn, had acquired

its leasehold interests for all the depths under the Parkey Ranch from Cleo Oil, Inc., who had a lease

with the original mineral owner, James R. Parkey. Each mineral owner in the chain of title, from

Parkey to Carrizo, was entitled to a share of royalty; PanAmerican and Carrizo also retained an

“overriding royalty,” a cost-free share of production.

       Carrizo acquired the Parkey lease as part of its “Kingdom Prospect,” envisioning

development of a cumulative 40,000-acre tract using horizontal drilling technology. As the best laid

plans of mice and men often go awry, the geologic structure underneath the Parkey Ranch was more

complicated than Carrizo expected, rendering horizontal drilling infeasible. Carrizo had also drilled

several vertical wells on the lease, but the production was “not commercial.” After spending

millions of dollars attempting to develop the Parkey lease, Carrizo abandoned its development

efforts. With the Parkey lease nearing expiration, Carrizo set its sights on a farmout arrangement.

       About a month before the Parkey lease’s expiration date, Carrizo and Barrow-Shaver began

negotiating a “drill-to-earn” farmout agreement, under which Carrizo would assign to

Barrow-Shaver certain Parkey-lease acreage for each well Barrow-Shaver drilled that met specified

standards. Barrow-Shaver sent Carrizo the initial draft of the farmout agreement, which did not

include a consent-to-assignment clause. Carrizo responded with a revised draft that included the

following provision:

       The rights provided to [Barrow-Shaver] under this Letter Agreement may not be
       assigned, subleased or otherwise transferred in whole or in part, without the express
       written consent of Carrizo which consent shall not be unreasonably withheld.

       In a subsequently revised draft, Carrizo deleted the “shall not be unreasonably withheld”

language. Barrow-Shaver initially objected to the deletion but eventually acquiesced after Carrizo


                                                  4
repeatedly gave verbal assurances that it would give “consent down the road.” The final and

effective version of the farmout agreement includes an assignment clause that reads:

       The rights provided to [Barrow-Shaver] under this Letter Agreement may not be
       assigned, subleased or otherwise transferred in whole or in part, without the express
       written consent of Carrizo.

       As required by the farmout agreement, Barrow-Shaver drilled a well on the Parkey Ranch

to hold the mineral lease before it expired. But—mice and men again—after expending $22 million

to drill the well, Barrow-Shaver’s operations under the farmout agreement failed.

       A year later, Raptor Petroleum II, LLC, a “well-funded start-up” founded by “mostly

ex-Anadarko engineers,” approached Barrow-Shaver about obtaining several mineral interests,

including an assignment of the Parkey lease farmout. Barrow-Shaver and Raptor reached a deal by

entering into a purchase-and-sale agreement, pursuant to which Barrow-Shaver would, for

$27.69 million, assign to Raptor a series of oil-and-gas agreements, including Barrow-Shaver’s

interests under the farmout agreement with Carrizo. The deal was set to close on July 3, 2012, but

to do so, Barrow-Shaver would first have to obtain 32 consents from 14 individual mineral-interest

holders.

       By the end of May, Barrow-Shaver had obtained all but one of the necessary

consents—Carrizo was the lone holdout. Eventually, on June 22, Carrizo sent Barrow-Shaver an

email with a single line—“Carrizo does not consent to the assignment.” With the closing date fast

approaching, Barrow-Shaver sought Carrizo’s reconsideration. Finally, on July 2, 2012—the day

before Barrow-Shaver and Raptor’s deal was to close—Carrizo insisted on a buy-out of the Parkey

lease for $5 million in lieu of consenting to the assignment. Chip Johnson, Carrizo’s CEO, later


                                                5
testified that the “sole reason” for Carrizo to continue withholding consent was that Barrow-Shaver

would not pay the $5 million asking price. Barrow-Shaver did not accept Carrizo’s offer, and

because Carrizo refused to consent, the deal with Raptor fell through.

       Barrow-Shaver sued Carrizo for breach of contract, fraudulent inducement, fraudulent

nondisclosure, and tortious interference with a contract. The trial court combined the two fraud

claims, which, along with the breach-of-contract claim, are now on appeal. The breach-of-contract

claim alleged Carrizo breached the farmout agreement by unreasonably withholding its consent to

the assignment. The parties agreed the consent-to-assign clause was unambiguous, but while

Barrow-Shaver argued industry custom and usage supplied a reasonableness limitation on the right

to withhold consent, Carrizo urged the provision’s silence about restraints equated to the parties’

agreement that Carrizo could withhold consent “for any reason,” reasonable or not. The trial court

agreed with Barrow-Shaver and allowed the parties to present testimony about whether industry

custom and usage limited Carrizo’s ability to withhold consent.

       After witnesses, including experts on both sides, had testified, the issue was submitted to the

jury with the following instruction:

       Did Carrizo fail to comply with the Farmout Agreement?

       You are instructed that the Farmout Agreement is silent about the reasons under
       which Carrizo could refuse consent to [Barrow-Shaver]’s assignment of the Farmout
       Agreement to Raptor. Therefore, you may consider evidence of industry custom and
       expectations in deciding whether Carrizo breached its agreement with
       [Barrow-Shaver]. [Barrow-Shaver] contends that there was a custom and usage in
       the oil and gas industry that a consent to assignment not be unreasonably withheld.
       Custom and usage refers to a practice that is so general and universal that the parties
       are charged with knowledge of its existence to such an extent as to raise a
       presumption that they dealt with reference to it.


                                                 6
Answering “yes,” the jury found that, in accordance with industry custom and usage, the consent

clause in the farmout agreement required Carrizo to act reasonably and Carrizo had breached the

contract by unreasonably withholding its consent. As damages, the jury awarded $27.69 million to

Barrow-Shaver, the exact amount of the consideration for the purchase-and-sale agreement between

Barrow-Shaver and Raptor.

         With respect to the fraudulent-inducement claim, Barrow-Shaver alleged Carrizo repeatedly

stated it would consent to an assignment of the farmout agreement even though it never intended to

do so and these misrepresentations induced Barrow-Shaver to enter the farmout agreement.

Barrow-Shaver’s fraudulent-nondisclosure claim focused on the time period it was negotiating with

Raptor and alleged Carrizo made material misrepresentations that created the false impression that

Carrizo would consent to the Raptor assignment. The trial court combined the two fraud claims and

gave the jury a general fraud instruction. The jury again sided with Barrow-Shaver, awarding

$1.7 million in fraud damages.5

         In moving for final judgment, Barrow-Shaver elected the breach-of-contract remedy over

the fraud remedy. Accordingly, the trial court rendered judgment for Barrow-Shaver, awarding

$27.69 million in contract damages along with $1 million in attorneys’ fees and $2.9 million in

prejudgment interest.

           Barrow-Shaver claimed fraud damages of $888,000 for converting the well on the Parkey lease into a saltwater
well and another $800,000 expended to keep some of the leases alive.

                 1. Trade Custom and Usage May Inform An Unambiguous Contract

         Disregarding the jury’s finding on trade custom and usage, the Court today holds that, as a

matter of law, the consent provision authorized Carrizo to withhold its consent for any reason, no

reason, or as a bargaining chip to extract a $5 million pay day at the eleventh hour.6 The Court

categorically discards trade custom and usage on the grounds that “the term [consent] can easily be

understood according to its plain, ordinary, and generally accepted meaning.”7                                  This is a

fundamental analytical mistake that ignores precedent.

         Consulting trade custom and usage to inform the meaning of words and expressions in a

contract is neither a novel idea nor a modern convention.8 More than a hundred years ago, we

acknowledged that,

         where there is nothing in the agreement to exclude the inference, the parties are
         always presumed to contract in reference to the usage or custom which prevails in
         the particular trade or business to which the contract relates; and the usage is

          Contrary to the Court’s construction of the contract as authorizing Carrizo to withhold consent for any reason,
the Court repeatedly denies that Carrizo could ever leverage its consent power to extort a payout from Barrow-Shaver.
Ante at 40. And contrary to the jury’s findings, the Court repeatedly denies that Carrizo did, in fact, act unreasonably
and wrongfully in refusing to consent to the assignment while at the same time conditioning consent on a $5 million
buyout when the deal with Raptor was at a make-or-break deadline. Id. at 39-40.

Notwithstanding the Court’s assertion to the contrary, even when terms “can easily be understood

according to [their] plain, ordinary, and generally accepted meaning,”10 industry custom and usage

informs the meaning of terms that might otherwise seem intuitive to industry outsiders.11 Numerous

states have long held so,12 and Texas is no exception.

         In Schaub v. Dallas Brewing Co., for example, the Court held that beer kegs were

“accessories, appliances, or appurtenances” based on industry usage.13 We reasoned that the

meaning of the terms “would depend on the use [the terms] were put to, their relation to the

business, as well as the common understanding or custom in such establishments.”14 We held that

“[e]vidence directed to such inquiries would be admissible” and, in that particular case, “it was

proved[] by persons of experience in the brewing business.”15

         Another well-known example is a baker’s “dozen.” In the baking industry, the term means

thirteen even when the ordinary understanding of “dozen” is twelve.16 Similarly, this Court has

noted that a “thousand” rabbits may mean 1,200; a “day” may mean 10 hours; and “4,000” shingles

may mean 4,500.17 Standing alone, none of these terms is industry specific; rather, lay people use

them on a daily basis. The Court’s holding today that trade custom and usage has no applicability

to terms that are “not susceptible to more than one meaning[] and [are] not industry or vocation

specific” is manifestly wrong.18 And if industry custom and usage can inform the meaning of an

ostensibly certain number, a soft term, like “consent,” could also carry a commercially significant

context-dependent meaning, so long as the party asserting the custom and usage can meet its burden

of proving the custom and usage has such regularity of observance as to justify an expectation that

it will be observed with respect to the transaction in question.19 Contrary to the Court’s assertion,

          “The existence and scope of a usage of trade are to be determined as questions of fact.”22

Here, both parties called witnesses to testify about the asserted custom and usage. Jason Perkins,

Raptor’s representative, testified that people in the oil-and-gas industry “would have the expectation

that [certain] factors [] would be considered in the decision to grant or withhold consent.” Bruce

Kramer, a leading scholar in the oil-and-gas industry, confirmed Perkins’s testimony and further

testified that those “factors” focus on the financial and technical expertise and reputation of the

potential assignee. This evidence raises a fact issue regarding whether industry custom and usage


specifications did not authorize any deviations); see also Nat’l Union Fire Ins. Co. v. CBI Indus., Inc., 907 S.W.2d 517,

               Section 222 of the Restatement (Second) of Contracts provides several illustrative examples:

          A promises to act as B’s agent in a certain business, and B promises to pay a certain commission for
          each “order.” By a local usage in that business, “order” means only an order on which the purchaser
          has paid a certain price. Unless otherwise agreed, the usage is part of the contract.

          A and B enter into a contract of charter party in which A promises to discharge the vessel “in 14
          days.” Usage in the shipping business may show this means 14 working days.

          A and B enter into a contract for the purchase and sale of “No. 1 heavy book paper guaranteed free
          from ground wood.” Usage in the paper trade may show that this means paper not containing over
          3% ground wood.

limited the circumstances under which Carrizo could withhold its consent to an assignment of the

farmout agreement. And because the existence and scope of a particular custom and usage is

ordinarily a question of fact, the issue was properly submitted to the jury,23 and we cannot disturb

the jury’s finding that the contracting parties understood the consent-to-assign clause to mean

consent could not be unreasonably withheld.24

         The Court’s categorical rejection of trade-custom-and-usage evidence leads the Court to the

erroneous conclusion that the consent clause is “silen[t] as to refusal or withholding of consent.”25

In so holding, the Court assumes express language is necessary for the consent clause to mean

consent cannot be unreasonably withheld. But this assumption fails because reasonableness is

already embedded in the contract through trade custom and usage. The Court’s contrary assertion

notwithstanding, reading a particular industry custom and usage into the consent provision would

not rewrite the agreement because the custom and usage preexisted the agreement and “the parties

are always presumed to contract in reference” to it “where there is nothing in the agreement to

exclude the inference.”26 The absence of an otherwise redundant reasonableness qualifier does not

deprive the clause of the meaning trade custom and usage confers.

         Indeed, Carrizo’s initial offering of a draft with reasonableness explicitly expressed indicates

Carrizo’s knowledge that an industry usage, as the jury found, imparts reasonableness into such a

clause. The revised draft dropping the express qualifier—while not explicitly allowing consent to

be withheld for any reason—is consistent with the jury’s finding that the usage was already part of

the parties’ contract. Because reasonableness was embedded in the clause, no additional covenants

or obligations would be imposed on Carrizo by reading the contract according to industry

expectations.27 Cases implying terms or imposing a duty of good faith and fair dealing when the

contract is silent—authority Carrizo and the Court rely on—are irrelevant to the analysis of what

the contract says in the first place.28

the consent clause’s meaning, but they both urge that any consideration of such evidence

necessitates admission of all evidence pertaining to the parties’ negotiation history—not just the

prior drafts and oral representations that were admitted into evidence, but also evidence of the

parties’ subjective beliefs.29 This, however, plainly violates the parol evidence rule. When a

contract is written and unambiguous, like the consent clause here, the parol evidence rule prohibits

consideration of oral or extrinsic evidence to modify or contradict the contract’s terms.30

        To circumvent this fundamental contract-construction principle, both the Court and

JUSTICE BOYD contend the parties’ negotiation history must be admitted into evidence—not to

establish the terms of the parties’ written contract—but to show the parties’ intent to exclude the

usage.31 But when the only purpose of extrinsic evidence is to show the parties intended the contract

to say something other than what it says, such evidence is inadmissible.32

        Parties can certainly contract around a trade usage, but the intent to do so must be clear from

the contract itself:

        Under the common law, a custom or usage may be excluded from the terms of the
        contract either expressly or by implication. It is not necessary that the parties state
        in terms that the usage is not adopted as part of the contract if they otherwise make
        their intention manifest. It is a sufficient ground for rejecting a custom as affecting
        the rights of parties to a contract that it is excluded by necessary implication of the
        contract itself. Evidence of custom or usage is therefore inadmissible when either
        expressly or impliedly excluded by the terms of the contract. . . . The test as to

         whether the custom or usage is repugnant to the contract is whether the custom or
         usage, if written into the contract, would make it not sensible or inconsistent.33


The determination of whether the parties did or did not intend to contract with respect to a trade

custom or usage depends on “the terms of the particular contract in dispute,” considered “as a whole,

including both its express words and its necessary implications.”34 Whether the parties intended to

negate a particular usage is thus determined by consulting the contract language. The authority the

Court and JUSTICE BOYD cite as requiring consideration of the negotiation history does not support

the proposition that evidence directed to the parties’ subjective intent is—contrary to the parol

evidence rule—admissible.35

         Carrizo could have contracted around trade custom and usage, but it chose not to.36 To limit

or exclude a trade custom or usage, parties can expressly agree that trade custom and usages will not

apply to the contract.37 Another method for excluding a trade usage is to define terms in a way that

differs from the industry understanding.38 Here, Carrizo could haven excluded the trade usage by

generally disclaiming any intent to contract with regard to a usage or expressly stating that consent

could be withheld for any or no reason. Carrizo not only failed to contract around the trade custom

and usage, it repeatedly assured Barrow-Shaver it would give consent—confirming, rather than

negating, an intent to conform to industry custom.39

         Even if evidence of the parties’ negotiations were admitted, it would yield, at best, equal

inferences. Perhaps the Court and JUSTICE BOYD are correct that if additional negotiation evidence

were admitted, the jury could infer the parties agreed to an unqualified consent clause because a

reasonableness limitation was expressly inserted and then purposefully removed from drafts of the

farmout agreement. Even so, the same circumstances—especially coupled with Carrizo’s oral

promises—are equally consistent with the parties’ understanding that the deleted language was

redundant because the consent clause was already subject to a reasonableness standard. Under the

in excluding it on that basis or on parol evidence grounds.40

          4. Trade Custom and Usage Is Not Equivalent to Judicially Imposed Terms

         Based on the false conclusion that the consent clause is “silent” as to withholding consent,

the Court refuses to read into the clause a reasonableness requirement as the jury found, alleging

courts should not supplement “terms [that] are immaterial to the farmout agreement.”41 This

misstates the law.

         First, the scope of trade custom and usage is much broader than the material and essential

terms the Court contemplates—trade custom and usage actually includes an array of practices not

just a single term like timing, price, or quantity.42 Second, and more importantly, when giving effect

to a trade custom and usage, a court is not imposing a definite term that the court itself considers

reasonable, but rather a usage formed by the industry. These distinctions explain why the

Restatement (Second) of Contracts treats these two contract-interpretation approaches differently

and defers to trade custom and usage—under Restatement section 204, courts may impose a

applicable trade custom and usage;44 in comparison, section 221 provides that trade custom and

usage prevails over terms courts might supply under section 204 and is not limited to supplementing

only material or essential terms.45 In portraying my analysis as “a veiled attempt to use industry

custom and usage to create a covenant of reasonableness and good faith,” the Court conflates these

interpretive approaches.46 Indeed, none of the authority the Court cites supports the proposition that

trade custom and usage is limited to supplying material or essential terms.47

         Mindful of the conceptual distinction between these two approaches, I am not proposing to

impose reasonableness on the parties as a matter of law; rather, reasonableness is woven into this

particular clause because in this particular context, industry custom and usage, as found by the jury,

demands so. Consulting trade custom and usage for contract interpretation is far from being a

newfangled idea. Courts act as gatekeepers in requiring proof to raise an issue about trade custom

and usage, and when parties have duly satisfied their burden of proof, we must trust our juries to

evaluate evidence of the existence and meaning of a proffered custom and usage.48 The Court’s

concern that introducing trade custom and usage would subject “every term, word, or phrase in every

agreement” to “litigation and ultimately a jury determination” is no more than groundless hysteria.49

The notion that trade custom and usage can inform the meaning of a contract’s terms is centuries old

and has yet to create the cataclysm the Court fears.50

5. The Court’s Holding Thwarts Oil and Gas Development and Distorts the Jury’s Findings

         Context matters when interpreting a contract,51 especially when industry custom and usage

is at issue.52 When the contractual context is considered here, the Court’s holding is even more

troubling. A farmout agreement is “[a] very common form of agreement between operators,


         48
            At bottom, the Court’s true quarrel is with the nature of the evidence the trial court relied on in finding a fact
issue about trade custom and usage. See RESTATEMENT (SECOND) OF CONTRACTS § 220(1) & cmt. b (usage is relevant
to interpretation if each party knew or had reason to know of the usage, so “a party who asserts a meaning based on usage
must show either that the other party knew of the usage or that the other party had reason to know of it”). The Court
avoids tackling the evidentiary issue head on by taking a back-door approach that effectively precludes any term with
an “ordinary” meaning from having a trade custom and usage. As trade custom and usage often informs the meaning
of words that are unambiguous in their ordinary or legal meaning, this approach abrogates trade custom and usage as
a viable contract-construction principle. See supra part II, A.1. Indeed, Carrizo challenged before the court of appeals
the sufficiency of the trade-custom-and-usage evidence Barrow-Shaver proffered, but Carrizo did not fully brief the
argument here. In any event, Carrizo’s challenge goes to the weight of evidence, and I would conclude the trial court
properly exercised its discretion in allowing evidence on trade custom and usage.

whereby a lease owner not desirous of drilling at the time agrees to assign the lease, or some portion

of it . . . to another operator who is desirous of drilling the tract.”53 As the facts of this case

illustrate, farmout agreements allow new parties with innovative ideas, more financial resources, or

more advanced technologies to undertake more efficient operations under the mineral lease while

allowing the farmor to preserve its leasehold interest.54 The testimony at trial underscores the point.

Brad Fisher, Carrizo’s representative, testified that Carrizo’s reason for arranging a farmout with

Barrow-Shaver was to embrace “new ideas” that Barrow-Shaver could bring to drilling horizontal

wells; and Scott Shaver, Barrow-Shaver’s founder, likewise considered Raptor a “Godsend” with

“a better idea” who “could do better.”

        By endorsing Carrizo’s behavior—which the jury found to be unreasonable and

fraudulent—the Court nullifies the fundamental goal of farmout agreements and frustrates public

policy. Because Carrizo did not consent, Raptor lost the chance to replace Barrow-Shaver as the

farmee to operate a lease that was no longer lucrative to Barrow-Shaver but still desirable to Raptor,

and all the mineral-interest holders in the chain of title lost the opportunity to receive their share of

royalty from Raptor’s drilling operations.            In fact, after the Raptor deal fell through and

Barrow-Shaver’s farmout expired, Carrizo did not drill any well on the tract and allowed the Parkey

lease to expire. The shenanigans the Court says two sophisticated parties explicitly agreed to allow

caused the minerals on the 22,000-acre Parkey tract to remain undeveloped, which is repugnant to

our statewide policy to promote oil-and-gas exploration and development.55 No one—including the

holdout party—benefits from the Court’s categorical holding.

        To blunt what will surely be a holding detrimental to the oil-and-gas industry, the Court

contrives to justify Carrizo’s assumed motivations by directly and indirectly implying that Raptor

was not a proper assignee,56 despite (1) the jury’s finding to the contrary and (2) the Court’s asserted

holding that reasonableness is entirely irrelevant. Ironically, the Court’s continued validation of

Carrizo’s purported motives exposes the weakness in its analysis: the Court holds that Carrizo could

withhold consent unreasonably under the terms of the contract without running afoul of public

policy but defends that conclusion only by assuming Carrizo had a valid reason for withholding

consent. Whether Raptor was a viable candidate and whether Carrizo behaved unreasonably under

the circumstances are questions of fact for the jury to resolve, not the Court. Here, without giving

a reason and as the sole hold-out, Carrizo pressed for a $5 million pay day knowing the clock was

running out on Barrow-Shaver’s deal with Raptor. The jury, as it was entitled to do, found Carrizo

acted unreasonably. Second-guessing the jury findings is merely a diversion from the unsettling and

expansive implications of today’s opinion.

        On that score, what is most disconcerting about the Court’s opinion is the absence of any

limiting principle. The Court’s reasoning is rooted in general contract principles and is highly

        Because I would hold that Barrow-Shaver prevails on its contract claim and Barrow-Shaver

elected that remedy, I would not reach the fraud claim. But if I were to reach the fraud claim, I

would conclude Barrow-Shaver has a viable fraudulent-inducement claim.

        Barrow-Shaver alleges, and the jury found, that Carrizo entered into the farmout agreement

with no intent to consent to an assignment despite its oral representations that it would do so and

contrary to contract terms that require it to reasonably do so. We have held that “a fraud claim can

be based on a promise made with no intention of performing, irrespective of whether the promise

is later subsumed within a contract” because “the legal duty not to fraudulently procure a contract

is separate and independent from the duties established by the contract itself.”57 We have recognized

that “[b]reach alone is no evidence that breach was intended when the contract was originally

made,” but “breach combined with ‘slight circumstantial evidence’ of fraud is enough to support a

verdict for fraudulent inducement.”58 And while fraudulent intent “is determined at the time the

party made the representation, it may be inferred from the party’s subsequent acts after the

representation is made.”59 The record here bears at least slight circumstantial evidence of intent not

to perform, and Carrizo does not challenge the fraud verdict for the lack of fraudulent intent.

Barrow-Shaver’s reliance on Carrizo’s verbal promises was justified. The analysis of this question

turns, in part, on what the contract says, and under a consent clause informed by trade custom and

usage, Carrizo’s verbal promises are entirely consistent with what the consent clause says.

Accordingly, I would hold Barrow-Shaver established justifiable reliance as a matter of law.

Nevertheless, because Barrow-Shaver elected to recover on its contract claim and could do so under

my disposition, it ultimately would not recover on its fraud claim.

       Unfortunately, my disposition of the contract claim has not carried the day. A majority of

the Court concludes the consent clause is unqualified, and under that interpretation of the contract,

the Court correctly concludes Barrow-Shaver would not be justified in relying on an oral

representation that consent would be granted when the contract imposes no obligation on Carrizo

to do so. I therefore concur with the Court’s judgment on the fraud claim pursuant to which

Barrow-Shaver takes nothing.

                                          III. Conclusion

       I would reverse and render judgment in Barrow-Shaver’s favor based on the jury’s finding

that Carrizo breached the farmout agreement by failing to act in accordance with the consent

provision as understood in the industry. Though I disagree with the Court’s contract analysis, the

disposition of Barrow-Shaver’s fraud claim turns on the contract’s interpretation, and under either

my disposition of the contract claim or the Court’s, Barrow-Shaver would not recover on its fraud

claim, albeit for distinctly different reasons. I therefore respectfully concur in part and dissent in

part to the Court’s opinion and judgment.
