1. Misrepresentation and the as-is clause
A party induced to contract by a material or fraudulent misrepresentation on which she justifiably relies may seek rescission. A representation can be misleading even if its literal words are narrowly true. Context, the question asked, and omitted qualifying facts matter.
Beverly specifically asked whether the roof was in good condition. Austin replied that he had never had a problem with it, despite receiving a manufacturer's notice that this very roof soon would leak. If he had never yet experienced a leak, his sentence may be literally accurate as a historical statement. In context, however, it communicates reassurance about condition while withholding information that fundamentally changes that impression. The known warning is particularly material because roof integrity substantially affects the warehouse's utility and value.
Beverly can establish intent to induce reliance from Austin's responsive reassurance during sale negotiations and his failure to reveal the notice. She asked the question, proceeded with the purchase, and suffered precisely the threatened problem immediately afterward. Those facts support actual reliance and materiality. A reasonable buyer may rely on a seller's specific response about a latent known problem even while undertaking ordinary inspection; the record does not establish that an inspection would have revealed the warning or impending failure.
Austin will emphasize the written sale as is and express absence of structural warranties. Those terms allocate ordinary condition and warranty risks and make a contract-based warranty claim weaker. They do not necessarily authorize a seller knowingly to induce agreement through a misleading half-truth or concealment. A general disclaimer differs from a clear, enforceable, specifically negotiated allocation of the very disclosed risk. Here the risk was not disclosed, and the clause does not expressly say Beverly knowingly accepts a manufacturer's prediction of imminent roof failure.
The court therefore should not treat the disclaimer as automatically defeating rescission for misrepresentation. Austin's literal-truth and agreed-risk arguments deserve discussion, but the specific question and known warning make Beverly's avoidance claim strong.
2. Nondisclosure as a separate basis
An arm's-length seller does not universally have to volunteer every fact that might affect a bargain. A duty to disclose can arise, however, to prevent a prior statement from being misleading, to correct a known basic mistake where good faith requires it, or concerning a material latent defect within the seller's knowledge under applicable property-sale principles.
Austin had information specifically directed to the warehouse roof that Beverly apparently lacked. By answering her condition inquiry incompletely, he had an especially clear obligation to avoid a misleading impression. The manufacturer did not merely publish a remote possibility that all roofs eventually age; it warned Austin last year that his roof soon would develop leaks. Disclosure would have allowed Beverly to price the risk, demand repair, or decline.
Austin can argue that the parties were commercial actors dealing at arm's length and that Beverly accepted an as-is building. No fiduciary relationship is described, and an outcome should not rest on inventing one. But a special fiduciary duty is unnecessary where the seller gives a misleading answer about a material condition he knows. The nondisclosure claim is therefore strong even if the court finds the exact words did not constitute an affirmative factual falsehood.
3. Rescission and restitution
Rescission unwinds the transaction rather than merely reimbursing a repair bill. Beverly ordinarily must elect or give appropriate notice promptly after discovering the ground, offer restoration of what she received, and account for benefits and necessary adjustments. Austin would return the purchase consideration, and Beverly would restore the warehouse, subject to the governing equitable and statutory rules. The immediate leak and prompt engagement of counsel support timely action; no long delay, affirmance after full knowledge, or inability to restore is given.
The valid written agreement and any parol-evidence objection do not categorically prevent proof that consent was obtained by fraud or material misrepresentation. Evidence of inducement is analytically distinct from adding an inconsistent warranty to an otherwise honestly negotiated writing. Beverly likely can rescind, though the court must determine reliance, materiality, and restoration from admissible truthful evidence rather than Lou's unsupported advocacy.
4. Lou and the expert's testimony
The February 2018 scenario is evaluated under California's former professional rules and the ABA framework. Lou owes competence, honesty, fairness, and candor. Selecting an engineer who has testified in Top-Tile litigation can be reasonable, but he must investigate the basis and consistency of the proposed opinion rather than offer a convenient expert without adequate preparation.
Prior testimony that Top-Tile always lasts at least five years conflicts sharply with the present claim that it never lasts that long. A changed opinion is not automatically perjury; an expert may learn new facts or reasonably revise conclusions. Lou should investigate that discrepancy rather than equate every inconsistency with knowledge of falsity. More seriously, he knows specifications say performance varies with climate and can be indefinite. The present universal claim that climate is irrelevant and failure occurs everywhere within five years contradicts that known information. At least the basis and reliability of the opinion require inquiry and correction.
Under ABA Rule 3.3, a lawyer may not knowingly offer false evidence and must take reasonable remedial measures upon learning material evidence is false, including disclosure to the tribunal if necessary under the rule even when confidentiality otherwise would apply. Lou should ask the expert to correct or clarify, avoid relying on a known false claim, and take the required remedial steps. Mere suspicion and actual knowledge should be distinguished, but Lou cannot deliberately ignore the contradiction and present unsupported universal facts as established.
California's former Rule 5-200 and Business and Professions Code section 6068(d) prohibit misleading a judge or jury by false statements or other artifice. California's confidentiality framework is not identical to the ABA's express candor override. Lou should obtain correction, use truthful evidence, and seek appropriate remedial or withdrawal measures if necessary while honoring the applicable limits on disclosure. The specifications and expert's public testimony are not automatically client secrets, and no confidence may be invented merely to excuse the continued misleading argument. Withdrawal also does not make an already false assertion true.
5. Closing argument
Lou repeated the expert's sweeping claims in closing despite the known contradictory material. If he knows them false, repeating them violates candor and honesty independently of whether he originally expected that testimony. Even if knowledge is disputed, competent advocacy requires an adequate factual basis, not selective use of assertions he has reason to believe misleading.
He also told the jury his own inspection confirmed the testimony. A lawyer generally must not assert personal knowledge of disputed facts outside the admitted record or place his own credibility before the jury. His inspection, unless properly offered through admissible evidence and appropriate witness procedures, is not evidence merely because he is counsel. Saying that his private observation proves the universal performance claim also exceeds what inspecting one roof could establish.
If his testimony becomes necessary, advocate-witness restrictions require separate analysis; the facts do not show a proper transition from lawyer to witness. The valid retainer and his experience do not excuse either introducing personal facts in closing or relying on misleading expert assertions. Beverly's underlying rescission claim can be strong while her lawyer's manner of proving it remains ethically improper.
