Duties to the Court and Third Parties: Candor, Advocacy, and Fairness
Key Takeaways
- CRPC 3.3 and ABA MR 3.3 impose CANDOR TOWARD THE TRIBUNAL: no knowingly false statement of fact or law, no offering evidence the lawyer KNOWS is false, and a duty to disclose DIRECTLY ADVERSE controlling legal authority not disclosed by opposing counsel; the candor duty can override confidentiality and continues to the conclusion of the proceeding.
- On discovering a client or witness has offered MATERIAL false evidence, the lawyer must take REASONABLE REMEDIAL MEASURES under both rules — remonstrate with the client, seek to withdraw or correct, and if necessary DISCLOSE to the tribunal; in California, the duty under § 6068(d) (never to mislead a judge by an artifice or false statement) supports this, though California historically gives the lawyer narrower latitude given § 6068(e) confidentiality.
- CRPC 3.4 and ABA MR 3.4 require FAIRNESS to opposing party and counsel: no unlawful obstruction, destruction, or concealment of evidence; no falsifying evidence or inducing false testimony; no disobeying tribunal rules without open challenge; no frivolous discovery; and (California-specific § 6068(d)) never to seek to mislead the judge.
- CRPC 3.1 / ABA MR 3.1 bar bringing or defending FRIVOLOUS claims (no nonfrivolous basis in law and fact), but a criminal defense lawyer may put the prosecution to its proof; CRPC 3.5 / MR 3.5 bar improper influence on judges/jurors and prohibited EX PARTE contact.
- Duties to THIRD PERSONS: CRPC 4.1 / MR 4.1 bar knowing false statements of material fact to third parties; California's NO-CONTACT rule, CRPC 4.2 / MR 4.2, bars communicating about the subject of the representation with a person the lawyer KNOWS is represented by counsel without that counsel's consent; CRPC 4.3 / MR 4.3 governs dealings with the unrepresented; CRPC 4.4 / MR 4.4 bars means with no purpose but to embarrass/burden and addresses inadvertently sent documents.
A lawyer is an advocate but also an officer of the court, and Rule 3.3 marks the point where the duty to the system constrains zealous advocacy. California Rule 3.3 and ABA Model Rule 3.3 both forbid a lawyer from knowingly making a false statement of fact or law to a tribunal or failing to correct a false statement of material fact or law previously made to the tribunal by the lawyer. They forbid offering evidence the lawyer KNOWS to be false; if a lawyer has offered material evidence and comes to know of its falsity, the lawyer must take reasonable remedial measures.
And they impose an affirmative DISCLOSURE duty: a lawyer must disclose to the tribunal legal authority in the controlling jurisdiction that is DIRECTLY ADVERSE to the client's position and is not disclosed by opposing counsel. This last duty surprises students — the adversary system does not require you to make the opponent's factual case, but it does require you to flag binding adverse precedent the opponent missed, because the court depends on the bar for accurate law.
The candor duties of Rule 3.3 apply even if compliance requires disclosing information otherwise protected by confidentiality, and they continue to the CONCLUSION OF THE PROCEEDING. California reinforces these obligations with Business & Professions Code section 6068(d), the statutory duty to employ those means only as are consistent with truth and never to seek to mislead the judge or any judicial officer by an artifice or false statement of fact or law.
The hardest candor scenario is the client or witness who testifies falsely, or the lawyer who discovers after the fact that evidence already offered was false. A lawyer may REFUSE to offer evidence (other than the testimony of a criminal defendant) that the lawyer reasonably believes is false.
But when the lawyer KNOWS the evidence is false and material, the rule mandates a sequence of REASONABLE REMEDIAL MEASURES: first, remonstrate with the client confidentially, urging the client to correct or withdraw the false evidence; if that fails, consider seeking to withdraw from the representation; and if withdrawal will not undo the effect of the false evidence, the lawyer must as a last resort DISCLOSE the situation to the tribunal, even over the client's objection and even though disclosure reveals confidential information.
The criminal defendant's right to testify complicates the picture: a lawyer who knows the defendant intends to commit perjury must counsel against it, may seek to withdraw, and under the ABA framework may ultimately have to disclose; California courts have wrestled with whether the defendant should instead testify in NARRATIVE form (the lawyer calls the defendant and lets him testify without the lawyer eliciting or arguing the false testimony).
The disciplined essay notes the tension between Rule 3.3's candor mandate and California's especially strong confidentiality duty under section 6068(e), and explains that Rule 3.3's remedial-disclosure requirement is one of the rare places the duty to the tribunal overrides confidentiality, but that California applies it cautiously, beginning with remonstration and withdrawal before any disclosure.
Rule 3.4 governs FAIRNESS to the opposing party and counsel and is the litigation-integrity rule. California Rule 3.4 and ABA Model Rule 3.4 prohibit a lawyer from unlawfully obstructing another party's access to evidence or unlawfully altering, destroying, or concealing a document or other material with potential evidentiary value, and from counseling or assisting another to do so (spoliation). They bar falsifying evidence, counseling or assisting a witness to testify falsely, and offering an unlawful inducement to a witness.
They prohibit advising a person other than a client to withhold relevant information from the other side, except that a lawyer may request a relative, employee, or agent of the client to refrain from voluntarily giving information if the lawyer reasonably believes their interests will not be adversely affected.
They forbid knowingly disobeying an obligation under the rules of a tribunal except for an open refusal based on a good-faith assertion that no valid obligation exists, and in trial forbid alluding to irrelevant or unsupported matters or asserting personal knowledge of contested facts or personal opinion as to a witness's credibility or a party's guilt. Rule 3.1 separately bars FRIVOLOUS positions: a lawyer shall not bring or defend a proceeding, or assert or controvert an issue, unless there is a basis in law and fact that is not frivolous, which includes a good-faith argument for an extension, modification, or reversal of existing law.
A crucial carve-out preserves the criminal defendant's rights: a lawyer for a defendant in a criminal proceeding, or a respondent in a proceeding that could result in incarceration, may nevertheless put the prosecution to its proof on every element. Rule 3.5 rounds out the litigation duties by barring a lawyer from seeking to influence a judge, juror, or official by means prohibited by law, and from engaging in improper EX PARTE communication with a judge or juror during the proceeding.
Beyond the courtroom, lawyers owe duties to people who are not their clients. California Rule 4.1 and ABA Model Rule 4.1 prohibit a lawyer, in the course of representing a client, from knowingly making a false statement of MATERIAL fact or law to a third person; the ABA version adds a duty to disclose a material fact when necessary to avoid assisting a client's crime or fraud, but California's narrower confidentiality regime limits that affirmative-disclosure overlay. The most heavily tested third-party rule is the NO-CONTACT rule.
California Rule 4.2 and ABA Model Rule 4.2 forbid a lawyer who is representing a client from communicating ABOUT THE SUBJECT OF THE REPRESENTATION with a person the lawyer KNOWS to be represented by another lawyer in the matter, unless the represented person's lawyer consents or the communication is authorized by law or court order.
When the represented party is an ORGANIZATION, the no-contact rule reaches the organization's current officers, directors, managing agents, and any constituent whose act or omission may be imputed to the organization or whose statements may constitute an admission — but generally not former employees, who a lawyer may contact. The rule applies even if the represented person initiates the contact, and even if the lawyer thinks the other lawyer is doing a poor job.
California Rule 4.3 and Model Rule 4.3 govern dealings with an UNREPRESENTED person: the lawyer must not state or imply that the lawyer is disinterested, must correct any misunderstanding about the lawyer's role, and must not give legal advice (other than to secure counsel) if the unrepresented person's interests conflict with the client's.
California Rule 4.4 and Model Rule 4.4 bar using means that have no substantial purpose other than to embarrass, delay, or burden a third person, or methods of obtaining evidence that violate the legal rights of a third person, and require a lawyer who receives a document or electronically stored information the lawyer knows or reasonably should know was inadvertently sent to promptly NOTIFY the sender.

- Inadvertently sent document (Rule 4.4) → promptly notify the sender.
During a hearing, a lawyer realizes that binding California Supreme Court precedent is directly adverse to her client's position, and opposing counsel has not cited it. What must she do?
A lawyer representing a plaintiff wants to call the defendant's CURRENT managing supervisor — whose decisions are central to the suit — to ask her about the events, knowing the defendant company is represented by counsel. The company's lawyer has not consented. May the plaintiff's lawyer contact the supervisor directly?
