Colorado Supreme Court Holds the Economic Loss Rule Does Not Bar Fraudulent Inducement Claims — Keys for Litigators and Drafters

On Jun. 23rd, the Colorado Supreme Court handed down its latest word on the economic loss rule (also called the “economic loss doctrine”), affirming a $215.2 million judgment against a contractor that concealed a known performance problem while negotiating a quarter-billion-dollar design-build agreement. In Veolia Water Technologies, Inc. v. Antero Treatment LLC, 2026 CO 52 (Jun. 23rd) a unanimous court held that the rule did not bar the owner’s fraud claim, because the misrepresentations occurred before the governing contract was signed and induced the owner to sign it. The court also declined to stretch the “interrelated contracts” doctrine to cover an ordinary series of two-party agreements—a move that would have let the rule swallow most fraud claims between parties with any prior dealing.

For businesses, transactional lawyers, and litigators in Colorado, Veolia is a useful marker of where the boundary between contract and tort sits when fraud precedes the deal.

Background: the Economic Loss Rule in Colorado

The economic loss rule is a judicially developed doctrine that keeps contract law and tort law in their respective lanes. As the court reaffirmed, a party that suffers only economic loss from breach of an express or implied contractual duty cannot bring a tort claim for that breach unless the defendant owed an independent duty of care under tort law. The rule enforces the parties’ bargained-for expectancy interests and preserves predictability in commercial dealings. (For our prior coverage of the Colorado Supreme Court’s recent economic loss rule decisions, see There Is No Exception to the Economic Loss Rule for Willful and Wanton Conduct and The Economic Loss Rule Has No Bearing on Whether the Colorado Governmental Immunity Act Bars a Plaintiff’s Claims.)

To decide whether the rule applies, Colorado courts look not to the type of damages claimed but to the source of the duty allegedly breached. If the parties memorialized the relevant duty in their contract, no independent duty exists and the rule bars the tort claim. If a duty of care exists at common law independent of the contract, the rule does not apply.

The facts: a fracking-wastewater plant and a hidden power problem

Antero, a group of affiliated oil-and-gas and midstream companies, needed a better way to dispose of the wastewater from its hydraulic fracturing operations. It hired Veolia, which designs and builds water-treatment facilities, to develop a plant called “Clearwater”- that would crystallize the wastewater’s solids into a stable, landfillable salt while leaving behind reusable water.

The parties proceeded in stages. Antero first paid Veolia $355,000 for a “Bench Scale” study, then $1.5 million under two “Limited Notice to Proceed” agreements and finally entered into a Design/Build Agreement (the “DBA”) under which it agreed to pay roughly $255.8 million for a turnkey facility. The DBA set two critical performance requirements: the waste salt had to be landfillable (no free liquids), and the facility’s power consumption could not exceed specified daily limits, because power costs passed through to Antero.

As the parties negotiated the DBA, Veolia grew concerned that the plant’s power-hungry chillers would exceed Antero’s consumption limits and quietly began redesigning the process. Then, just four days before the DBA was signed, Veolia discovered it had significantly underestimated the chillers’ power needs and that the facility would likely exceed Antero’s maximum. It did not tell Antero and signed the deal. Eight days after signing, Veolia proposed a change order to account for the underestimation, marketing the redesign internally as a “WIN/WIN” and presenting it to Antero as “design optimizations.” Veolia’s own people had flagged that the redesign could compromise the salt’s quality—but Veolia again said nothing, assuring Antero the salt would be stable enough to landfill. Antero agreed to the change order.

The plant ultimately produced a “soupy salt” that leaked from trucks and storage buildings and could not be landfilled without expensive, never-contemplated solidification work. When Veolia told Antero the salt quality would not improve and that it was “Antero’s problem,” Antero terminated the DBA and mothballed the facility. Both parties sued. After a bench trial, the trial court found that Veolia had fraudulently concealed its inability to meet the power guarantee to induce Antero to sign the DBA, held that the economic loss rule did not bar the fraud claim, and awarded Antero $215.2 million plus attorney fees under the DBA’s fee-shifting clause. The court of appeals affirmed on different grounds, and the Supreme Court granted certiorari.

The holding: pre-contractual fraud falls outside the Economic Loss Rule

The Colorado Supreme Court affirmed, on somewhat different grounds, and rejected both pillars of Veolia’s defense.

No network of interrelated contracts. Veolia argued that its successive agreements together formed an interrelated network establishing one broad, ongoing relationship, so that any misrepresentations were made “in the course of” contract performance and were governed by contractual duties. The court disagreed. The parties had signed a series of distinct, stand-alone agreements, none of which obligated either side to proceed to the next. Unlike the multi-party arrangements in which interlocking contracts allocate risk among parties who may have no direct contract with one another, this case involved two parties signing successive bilateral agreements, and the DBA was a fully integrated, stand-alone contract. Its integration clause did not change the result; it merely carried forward duties the parties chose to keep.

Pre-contractual fraud is fraudulent inducement. With the interrelated-contracts theory off the table, the case became straightforward. The misrepresentations occurred before the DBA was signed and induced Antero to sign it—Veolia concealed its inability to meet the power guarantee, a term the trial court found was critical and without which Antero would not have signed. That is classic fraudulent inducement: the violation of an independent tort duty that the economic loss rule does not bar.

An independent-duty backstop. The court added that the result would hold even if the misrepresentations were treated as post-contractual. The only possible contractual source of a duty not to misrepresent—the implied covenant of good faith and fair dealing—reaches only a party’s discretionary authority over open terms like quantity, price, or timing, and Veolia had no discretion to alter Clearwater’s core salt-quality or power requirements without Antero’s written consent. The DBA itself, moreover, carved “gross negligence, fraud or willful misconduct” out of its damages cap.

The court affirmed and remanded for a determination of Antero’s reasonable attorney fees as the prevailing party.

Key takeaways

• Timing is everything. The decisive fact was when the fraud occurred. Misrepresentations that induce a party to sign sound in tort and survive the economic loss rule; misrepresentations about how a party later performs are far more likely to be subsumed by the contract. Counsel pleading or defending fraud claims should anchor the analysis to the moment of contract formation.
• A history of dealing is not a single relationship. Parties cannot convert a series of discrete, stand-alone bilateral contracts into one “interrelated network” to invoke the economic loss rule. The doctrine remains tethered to genuinely interlocking, often multi-party arrangements—not ordinary sequential deals between the same two companies.
• Integration clauses don’t bar fraud in the inducement. Folding prior obligations into a later, fully integrated agreement does not transform pre-contractual deceit into a mere contract dispute.
• The good-faith covenant has limits. Because the implied covenant of good faith and fair dealing reaches only discretionary performance terms, it will not subsume a tort duty where the contract fixes the relevant requirement and leaves the defendant no discretion to change it.
• Draft with the carve-out in mind. The DBA’s damages-cap exception for “fraud or willful misconduct” reinforced that the parties anticipated fraud claims outside the contract’s remedial scheme. Risk-allocation provisions should be drafted deliberately, because courts will read them as evidence of what the parties did, and did not, bargain to limit.
