Fourth Court Addresses Subject Matter Jurisdiction Over Hypothetical JOA Declarations and Cross-Netting of Multi-Agreement Obligations

1776 Energy Partners, LLC v. Marathon Oil EF, LLC Court of Appeals of Texas, San Antonio 04-20-00304-CV resolved
By Joel Reese · July 06, 2026 Court of Appeals of Texas, San Antonio

The San Antonio Court of Appeals held that a trial court lacked subject matter jurisdiction under the UDJA to render a declaratory judgment resolving hypothetical obligations under a joint operating agreement where the actual controversy—whether Marathon owed 1776 unpaid costs, interest, and revenues under three separate JOAs—turned on undisputed facts that Marathon never paid required cash calls. The court affirmed summary judgment for 1776 on its breach of contract claim seeking unpaid JOA obligations, rejecting Marathon's challenges to damage calculations that cross-netted amounts owed across multiple agreements and affirming exclusion of Marathon's fraud counterclaim for failure to establish a duty to disclose.

Background and Business Context

1776 Energy Partners, LLC and 1776 Energy Operators, LLC (collectively "1776") brought suit against Marathon Oil EF, LLC and Marathon Oil EF II, LLC (collectively "Marathon") for breach of contract and declaratory judgment regarding the parties' rights and obligations under three joint operating agreements (JOAs). The agreements governed how the parties would share expenses and revenues from oil wells drilled in an area where both held ownership interests. Marathon counterclaimed for breach of contract, declaratory judgment, and fraud. The 218th District Court in Karnes County granted 1776 summary judgment on its breach of contract claim, excluded testimony on Marathon's future damages, and ultimately rendered judgment in favor of 1776 while awarding attorney's fees to both parties.

The Jurisdictional Issue: Hypothetical Declarations Under the UDJA

A central issue on appeal concerned whether the trial court had subject matter jurisdiction to render a declaratory judgment that the first JOA did not require Marathon to pay its existing obligations under the second and third agreements in order to participate in drilling new wells. The Court of Appeals held the trial court lacked jurisdiction over this claim, finding it resolved only a hypothetical situation rather than an actual controversy. As the court explained,

"a Uniform Declaratory Judgments Act (UDJA) claim that seeks a declaration of what the law would be on a hypothetical set of facts is not ripe for adjudication, a trial court lacks subject matter jurisdiction to render such a declaration."
The undisputed facts established that Marathon never paid the cash calls required to participate in the new wells, making any declaration about what would have been required had Marathon chosen to participate purely academic. The court emphasized that
"[t]o constitute a justiciable controversy, there must exist a real and substantial controversy involving a genuine conflict of tangible interests and not merely a theoretical dispute."

Summary Judgment on Breach of Contract Claims

The court affirmed the trial court's grant of summary judgment to 1776 on its breach of contract claim. Marathon challenged whether 1776's summary judgment motion sufficiently pleaded actual damages, but the court found the motion adequate because it "asked the court to determine that defendant breached the agreement by failing to pay revenues and to pay costs and expenses and to award plaintiff 'all such other and further relief to which it may be entitled,'" and the body of the motion identified specific amounts owed and cited supporting evidence. Marathon also challenged the summary judgment affidavit of 1776's employee, arguing lack of personal knowledge, but the court rejected this argument, noting that

"[a]n affiant's assertion of personal knowledge may be based on a review of corporate business records."
Marathon further argued that 1776 was required to plead and prove a right to setoff revenues it owed to Marathon, but the court found no such requirement under the circumstances.

Cross-Netting and Damage Calculations

Marathon contended the trial court erred by considering cross-netted amounts owed between the parties under the second and third agreements when calculating damages under the first agreement. The Court of Appeals found that even if this constituted error, it did not result in an improper judgment because

"there was no indication that application of cross-netted amounts resulted in a judgment that ordered defendant to pay amounts it did not actually owe."
The court also rejected Marathon's argument that its proposed third amended counterclaim should have been allowed, finding it "prejudicial on its face" and that Marathon failed to show the judgment against its repudiation and anticipatory breach counterclaims turned on the exclusion of future damages testimony.

Fraud by Nondisclosure Claim

The court affirmed the directed verdict against Marathon's fraud counterclaim, holding that

"plaintiff had no duty to disclose what it planned to do with funds requested from defendant to participate in new wells, as would support defendant's counterclaim for fraud by nondisclosure."
This ruling reinforces the principle that parties to commercial agreements generally have no affirmative duty to disclose their business plans or intended uses of funds absent special circumstances creating such a duty.

Implications for Joint Operating Agreement Disputes

This decision provides important guidance for practitioners handling JOA disputes in several respects. First, it reinforces that declaratory judgment actions must resolve actual controversies, not hypothetical scenarios about what obligations might exist under different factual circumstances. Second, it confirms that operators seeking summary judgment on unpaid JOA obligations can satisfy pleading requirements through motions that identify specific amounts owed and cite supporting evidence, even without separately pleading each element of damages in the prayer. Third, the decision suggests Texas courts may permit cross-netting of obligations across multiple related agreements between the same parties, at least where doing so does not result in a party paying amounts not actually owed. Finally, the rejection of Marathon's fraud claim underscores the limited circumstances under which nondisclosure claims will succeed in arm's-length commercial transactions between sophisticated parties operating under written agreements.
