Rule 4.4 Respect for the Rights of Third Persons

Chapter 4: Transactions with Persons Other Than Clients

(a) In representing a client, a lawyer shall not: (1) use means that have no substantial purpose other than to embarrass, delay, or burden a third person or knowingly use methods of obtaining evidence that violate the legal rights of such a person; or (2) threaten to present a criminal or lawyer disciplinary charge for the purpose of obtaining an advantage in a civil matter.

(b) A lawyer who receives information (including, but not limited to, a document or electronically stored information) relating to the representation of the lawyer’s client that the lawyer knows or reasonably should know is protected by RPC 1.6(including information protected by the attorney-client privilege or the work-product rule) and has been disclosed to the lawyer inadvertently or by a person not authorized to disclose such information to the lawyer, shall: (1) immediately terminate review or use of the information; (2) notify the person, or the person's lawyer if communication with the person is prohibited by RPC 4.2, of the inadvertent or unauthorized disclosure; and (3) abide by that person's or lawyer's instructions with respect to disposition of written information or refrain from using the written information until obtaining a definitive ruling on the proper disposition from a court with appropriate jurisdiction.
