California Bar Duties to Court
Last updated: May 2, 2026
Duties to Court questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Under Cal. RPC 3.3 (candor toward the tribunal), a lawyer must not knowingly make a false statement of fact or law to a tribunal, must disclose directly adverse controlling legal authority in the controlling jurisdiction not disclosed by opposing counsel, and must not offer evidence the lawyer knows to be false. If a lawyer's client or witness has offered material false evidence, the lawyer must take reasonable remedial measures, including, if necessary, disclosure to the tribunal — and these duties apply even if compliance requires disclosure of information otherwise protected by Cal. RPC 1.6 and Cal. Bus. & Prof. Code § 6068(e). Independent of Rule 3.3, B&P § 6068(d) imposes the foundational California statutory duty never to seek to mislead a judge or judicial officer by an artifice or false statement of fact or law. Related duties include Cal. RPC 3.1 (no frivolous claims), Cal. RPC 3.4 (fairness to opposing party — no obstruction, falsification, or unlawful evidence destruction), and Cal. RPC 3.5 (no improper ex parte contact with judges or jurors).
Elements breakdown
Cal. RPC 3.3(a)(1) — False Statement of Fact or Law to Tribunal
A lawyer shall not knowingly make a false statement of fact or law to a tribunal or fail to correct a false statement of material fact or law previously made to the tribunal by the lawyer.
- Statement made to a tribunal
- Statement is of fact or law
- Statement is false
- Lawyer knows of falsity (actual knowledge, may be inferred)
- Or: failure to correct prior material false statement
Cal. RPC 3.3(a)(2) — Duty to Disclose Adverse Legal Authority
A lawyer shall not knowingly fail to disclose to the tribunal legal authority in the controlling jurisdiction known to be directly adverse to the client's position and not disclosed by opposing counsel.
- Legal authority in the controlling jurisdiction
- Authority is directly adverse to client's position
- Lawyer knows of the authority
- Opposing counsel has not disclosed it
- Failure to disclose is knowing
Cal. RPC 3.3(a)(3) — Offering False Evidence
A lawyer shall not offer evidence the lawyer knows to be false; if false material evidence has been offered, the lawyer shall take reasonable remedial measures including, if necessary, disclosure to the tribunal.
- Lawyer offers (or has offered) evidence
- Evidence is material
- Lawyer knows the evidence is false
- Lawyer fails to take reasonable remedial measures
- Permissive refusal allowed if lawyer reasonably believes (not knows) evidence is false, except a criminal defendant's testimony
Cal. RPC 3.3(b) — Remedial Measures for Criminal or Fraudulent Conduct
A lawyer who knows that a person intends to engage, is engaging, or has engaged in criminal or fraudulent conduct related to the proceeding shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal.
- Person involved in proceeding (client or witness)
- Criminal or fraudulent conduct related to the proceeding
- Lawyer has actual knowledge
- Lawyer must take reasonable remedial measures
- Disclosure required if necessary, even over confidentiality
Cal. RPC 3.1 — Meritorious Claims and Contentions
A lawyer shall not bring or defend a proceeding, or assert or controvert an issue, without a basis in law and fact that is not frivolous, including a good-faith argument for extension, modification, or reversal of existing law.
- Lawyer brings, defends, asserts, or controverts
- Position lacks basis in law and fact
- Position is frivolous (no good-faith argument)
- Criminal defense exception: may require prosecution to put on its case
Cal. RPC 3.4 — Fairness to Opposing Party and Counsel
A lawyer shall not unlawfully obstruct another party's access to evidence, falsify evidence, counsel a witness to testify falsely, or knowingly disobey a court obligation, and shall not allude in trial to inadmissible or unsupported matter.
- Unlawful obstruction, alteration, destruction, or concealment of evidence
- Falsifying evidence or counseling false testimony
- Knowing disobedience of a tribunal's obligation
- Improper allusion at trial to matter not reasonably believed admissible
- Improper payments to fact witnesses for testimony content
Cal. RPC 3.5 — Impartiality and Decorum of the Tribunal
A lawyer shall not seek to influence a judge, juror, or court official by means prohibited by law, and shall not communicate ex parte with such persons during the proceeding except as permitted by law or court order.
- Communication with judge, juror, prospective juror, or court official
- Outside scope authorized by law or order
- During the pendency of the proceeding
- Or: any prohibited means of influencing impartiality
- Or: post-discharge juror contact that is harassing, coercive, or prohibited
Cal. Bus. & Prof. Code § 6068(d) — Statutory Duty Never to Mislead the Court
It is the duty of an attorney 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.
- Attorney owes duty to court
- Means used must be consistent with truth
- No artifice or trick
- No false statement of fact
- No false statement of law
- Statutory — violation is independent ground for discipline
Common examples:
- Concealing a controlling appellate decision
- Citing a reversed case as good law
- Making representations of fact at oral argument the lawyer knows are false
- Permitting a misimpression created by the lawyer's prior statement to stand uncorrected
Common patterns and traps
The Confidentiality-Trumps-Candor Trap
This trap baits you with the (true) general rule that California has unusually strict confidentiality under B&P § 6068(e) and Cal. RPC 1.6 — narrower exceptions than the ABA Model Rules. The wrong answer applies that general rule reflexively to a Rule 3.3 candor problem and concludes the lawyer must remain silent. The correct answer recognizes that Cal. RPC 3.3(c) expressly subordinates confidentiality to the tribunal-candor duty during a proceeding.
A choice that says 'No, the lawyer must not disclose because California's confidentiality duty is absolute' or 'because the information was learned from the client.' The choice is doctrinally seductive in any other context but wrong here.
The Adverse-Authority Jurisdiction Switch
Cal. RPC 3.3(a)(2) requires disclosure only of adverse controlling authority. Distractors exploit confusion about what 'controlling' means in California — they offer choices framed around persuasive out-of-state authority, federal authority irrelevant to the state-law issue, or unpublished California decisions (which generally are not citable under Cal. R. Ct. 8.1115). The correct answer focuses tightly on whether the authority is binding in the forum.
A choice that says the lawyer must disclose a Ninth Circuit case adverse to client's state-law contract argument, or that the lawyer need not disclose a published California Court of Appeal decision because it 'isn't from the Supreme Court.'
The Passive-Non-Use Fallacy
When a client has already given false testimony, a candidate may believe the lawyer satisfies Rule 3.3 by simply not referring to that testimony in closing or future questions. California (like the ABA) rejects passive non-use — once material false evidence has been offered, the lawyer must take affirmative reasonable remedial measures, escalating to disclosure if remonstration and withdrawal cannot cure it.
A choice reading 'No discipline, because the lawyer did not rely on or repeat the false testimony in closing argument.'
The Ex Parte Innocent-Topic Trap
Cal. RPC 3.5(b) forbids ex parte communication with a judge during the proceeding except as authorized by law. Distractors permit a 'brief, friendly, non-substantive' chat with the judge — about an upcoming bar event, a scheduling matter discussed casually outside chambers, or a courtesy heads-up. Unless the law or court order authorizes it, even an apparently innocuous communication during pendency can violate the rule.
A choice saying 'Permissible, because the conversation did not concern the merits.' The rule does not turn solely on whether the topic was 'merits-based.'
The 'Reasonably-Believes' vs. 'Knows' Calibration
Cal. RPC 3.3(a)(3) bars offering evidence the lawyer knows is false but only permits refusing to offer evidence the lawyer reasonably believes is false (with a carve-out for a criminal defendant's own testimony). Distractors flip these standards — making the lawyer either too aggressive (refusing testimony on a hunch) or too passive (offering testimony despite actual knowledge of falsity).
A choice that says the lawyer 'must refuse to call the witness because the lawyer suspects the testimony is fabricated' — overstating the duty when there is no actual knowledge.
How it works
Imagine you represent Reyes, a civil defendant in San Diego Superior Court. Mid-trial, Reyes admits to you on a break that the alibi testimony he gave that morning — that he was in Sacramento on the date of the alleged conduct — was a lie. Under Cal. RPC 3.3(a)(3) and 3.3(b), your duty is now triggered: you have actual knowledge that material evidence offered to the tribunal is false. The rule sequences your response — first, remonstrate with Reyes and seek his consent to correct the record; if he refuses, you must consider withdrawal; if withdrawal will not undo the false evidence, you must disclose to the tribunal as a last resort, even though the information is otherwise protected by Cal. RPC 1.6 and B&P § 6068(e). The duty of candor under Rule 3.3 expressly trumps confidentiality in this narrow context — that is the structural answer the grader wants. Doing nothing, or merely declining to refer to the false testimony in closing argument, is not enough; passive non-use does not cure offered false evidence under California's remedial-measures framework.
Worked examples
Is Liu subject to discipline?
- A No, because Liu's duty of confidentiality under Cal. RPC 1.6 and B&P § 6068(e) prohibits Liu from disclosing client communications.
- B No, because Liu satisfied Liu's obligations by refraining from referring to the false testimony in subsequent questioning and in closing argument.
- C Yes, because Liu was required to take reasonable remedial measures, including, if necessary, disclosure to the tribunal under Cal. RPC 3.3. ✓ Correct
- D Yes, because Liu had a duty under Cal. RPC 1.16 to withdraw immediately upon learning of the false testimony, regardless of any remedial steps.
Why C is correct: Under Cal. RPC 3.3(a)(3) and 3.3(b), once Liu actually knew Patel had given material false testimony, Liu was required to take reasonable remedial measures — remonstrate, seek to withdraw if remonstration failed, and ultimately disclose to the tribunal if necessary to undo the false evidence. Cal. RPC 3.3(c) makes clear that this duty applies even when compliance requires disclosure of information otherwise protected by the duty of confidentiality. Passive non-use of the testimony is not enough.
Why each wrong choice fails:
- A: This is the classic California confidentiality-trumps-candor trap. While California's confidentiality duty is unusually strict, Cal. RPC 3.3(c) expressly subordinates confidentiality to candor when the tribunal-candor duty is triggered by material false evidence. (The Confidentiality-Trumps-Candor Trap)
- B: California rejects passive non-use as a remedy under Rule 3.3. Once material false evidence has been offered, the lawyer must affirmatively act to undo it, escalating to disclosure if remonstration and withdrawal will not suffice; merely declining to repeat or rely on the testimony does not discharge the duty. (The Passive-Non-Use Fallacy)
- D: Although withdrawal can be part of the remedial sequence, Rule 3.3 does not impose a flat 'withdraw immediately' rule. The first step is remonstration; withdrawal is required only if it will undo the harm, and disclosure is mandatory if withdrawal will not suffice. Framing withdrawal as the sole or first duty misstates the sequenced framework.
Is Reyes subject to discipline under Cal. RPC 3.3(a)(2)?
- A Yes, because the 2022 case is a published California Court of Appeal decision and is therefore directly adverse controlling authority that opposing counsel did not disclose. ✓ Correct
- B Yes, because any time California appellate authority is adverse to the client's position, the lawyer must disclose it whether or not opposing counsel cites it.
- C No, because a Third District opinion is not strictly binding on the Second District, so it is not 'controlling' authority within the meaning of Cal. RPC 3.3(a)(2).
- D No, because Cal. RPC 3.3(a)(2) requires disclosure only of California Supreme Court decisions, not Court of Appeal decisions.
Why A is correct: Although districts of the Court of Appeal are not strictly bound by each other, a published California Court of Appeal opinion is binding on all California superior courts under Auto Equity Sales and is recognized as controlling authority in California for purposes of Cal. RPC 3.3(a)(2) when directly adverse and not disclosed by opposing counsel. The duty turns on whether authority is directly adverse and within the controlling jurisdiction — not on whether it issues from the highest court of the jurisdiction.
Why each wrong choice fails:
- B: This overstates the rule. Cal. RPC 3.3(a)(2) is conditioned on opposing counsel's failure to disclose. If opposing counsel had cited the case, Reyes would not have an independent disclosure duty under Rule 3.3(a)(2), even though tactical and competence considerations might still favor citation.
- C: This misuses the 'binding/non-binding' framework. The duty of candor sweeps in directly adverse authority of the controlling jurisdiction; published California Court of Appeal decisions are controlling for these purposes even if a different district issued them. Treating the rule as coextensive with strict horizontal stare decisis misreads Cal. RPC 3.3(a)(2). (The Adverse-Authority Jurisdiction Switch)
- D: Nothing in Cal. RPC 3.3(a)(2) limits the duty to Supreme Court decisions. Published intermediate appellate decisions are routinely the controlling authority on point, and many California-bar candor questions test exactly this distinction. (The Adverse-Authority Jurisdiction Switch)
Is Liu subject to discipline under Cal. RPC 3.5?
- A No, because the conversation did not concern the merits of the pending matter and the judge did not respond substantively.
- B No, because the encounter was a chance public meeting rather than a planned ex parte contact, and chance meetings are categorically exempt from Rule 3.5.
- C Yes, because Liu communicated ex parte with the judge during the pendency of the proceeding regarding the matter, and the communication was not authorized by law or court order. ✓ Correct
- D Yes, but only if Judge Kapoor failed to disclose the encounter on the record at the next hearing.
Why C is correct: Cal. RPC 3.5(b) forbids communication ex parte with the judge during the pendency of the matter except as permitted by law or court order. Liu's comment — even framed as 'not about the merits' — was about the case and the client's posture in it, made to the assigned judge during pendency, with opposing counsel absent. The rule does not turn solely on whether the topic is technically 'merits-based'; communicating about the matter outside the presence of opposing counsel is the violation.
Why each wrong choice fails:
- A: This is the ex parte innocent-topic trap. Rule 3.5(b) does not limit its prohibition to merits discussions. Communicating about the case — including about the client's stress and how it 'comes through in the papers' — falls within the rule when made ex parte during pendency. (The Ex Parte Innocent-Topic Trap)
- B: There is no categorical 'chance meeting' exemption in Cal. RPC 3.5. While a brief social greeting unrelated to any matter would not violate the rule, the moment Liu used the encounter to communicate about the pending case, the prohibition was triggered.
- D: The lawyer's discipline does not depend on what the judge later does. Liu's duty under Rule 3.5 is independent of any disclosure obligation the judicial canons impose on Judge Kapoor, and the violation is complete when the prohibited communication is made.
Memory aid
FACE the court: False statements forbidden, Adverse authority disclosed, Correct prior falsities, Evidence-not-knowingly-false offered. And remember the California statutory backstop: B&P § 6068(d) — 'no artifice, no false statement.'
Key distinction
The single most important distinction is duty-to-tribunal vs. duty-of-confidentiality. Under Cal. RPC 3.3, when a client has offered material false evidence and refuses to correct it, the lawyer's duty of candor to the tribunal overrides the duty of confidentiality under Cal. RPC 1.6 / B&P § 6068(e). Graders test whether you recognize that California — like the ABA — sequences remedial steps (remonstrate, seek to withdraw, disclose) and ultimately requires disclosure as a last resort. This is the inverse of the default rule that confidentiality controls.
Summary
In California, a lawyer's duties to the tribunal — anchored by Cal. RPC 3.3 and B&P § 6068(d) — require active candor, disclosure of directly adverse controlling authority, remedial measures (including disclosure as a last resort) when material false evidence has been offered, and abstention from improper ex parte contact, frivolous filings, and obstruction.
