Lawyer Withholds Adverse Precedent
Francisco Frost represents a client seeking to enforce a contract clause. During oral argument before the state supreme court, Frost knows of a recent controlling decision that directly rejects his client's interpretation. Opposing counsel never cites the case. Frost remains silent and the court rules for his client. The disciplinary board later finds that Frost violated his disclosure duty under the rules.
Lawyer Stays Silent on Client Fraud
Faye Fuller represents a client who is negotiating a loan with a bank. Fuller learns her client intends to submit falsified financial statements. Disclosure to the bank would prevent the fraud, yet Fuller says nothing. The bank later sues the client and reports Fuller to the bar. The grievance committee finds that Fuller assisted the fraud by failing to disclose the material fact.
Bar Applicant Omits Prior Discipline
Fatou Fall applies for admission to the bar. She knows the character committee is unaware of a prior suspension in another state. When the committee asks about her disciplinary history, Fall provides an incomplete answer that leaves the misapprehension uncorrected. The committee later discovers the omission and denies admission on that ground alone.
Frequently Asked3
Does a lawyer's duty to disclose adverse authority apply only when opposing counsel has already cited the case?+
No. The duty exists whenever the lawyer knows of controlling adverse authority in the jurisdiction that opposing counsel has not disclosed. The rule requires disclosure regardless of whether opposing counsel has mentioned the case.

Can a prosecutor avoid a due-process violation by showing that the defense never requested the exculpatory evidence?+
No. The constitutional obligation to disclose favorable, material evidence applies whether or not the defense makes a request. The duty is triggered by the prosecution's possession of the evidence and its favorable, material character.
Supporting sources
Does nondisclosure during voir dire automatically require a new trial?+
No. A juror's failure to disclose information supports a new trial only if it demonstrates implied bias that probably affected the verdict. Courts consider whether the undisclosed information would have led to a successful challenge for cause and whether the error was harmless.

Seller Conceals Structural Defect
Farah Fox agrees to sell her warehouse to Fusion Power. Fox knows the roof has hidden water damage that will require immediate replacement. She says nothing during negotiations even though the buyer would have walked away or demanded a price reduction. After closing, Fusion discovers the defect and sues. The court holds Fox liable for the nondisclosure because she had a duty to speak.
Brokerage Fails to Reveal Market Premium
Fumiko Fujimoto and other tribal members sell shares to non-tribe buyers arranged by the defendants. The defendants know the shares trade at a substantial premium in a developed non-Indian market but say nothing. The sellers later sue for damages. The Supreme Court holds that positive proof of reliance is unnecessary in this primarily nondisclosure setting because the withheld facts were material.

Merger Without Misrepresentation Claim
Freya Freeman and other minority shareholders challenge a short-form merger that cashes them out at a price they believe is too low. They allege no misrepresentation or omission of fact, only that the merger lacked a valid corporate purpose. The Supreme Court dismisses the Rule 10b-5 claim, explaining that the statute reaches only conduct involving manipulation or deception, not mere breaches of fiduciary duty.
