Here is the corresponding Arizona rule:
ER 3.3. Candor Toward the Tribunal
(a) A lawyer shall not knowingly:
(1) 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;
(2) fail to disclose to the tribunal legal authority in the controlling jurisdiction known to the lawyer to be directly adverse to the position of the client and not disclosed by opposing counsel; or
(3) offer evidence that the lawyer knows to be false. If a lawyer, the lawyer's client or a witness called by the lawyer has offered material evidence and the lawyer comes to know of its falsity, the lawyer shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal. A lawyer may refuse to offer evidence, other than the testimony of a defendant in a criminal matter, that the lawyer reasonably believes is false.
Nurmi must offer Jodi's testimony, even if he reasonably believes it is false. To do otherwise would be a violation of his professional responsibility and his duty of loyalty to his client and zealous advocacy.
Only if he knows the testimony or evidence is false is he prohibited from eliciting or offering it.
