RULE 4.2 COMMUNICATION WITH PERSON REPRESENTED BY COUNSEL
In representing a client, a lawyer shall not communicate about the subject of the representation with a person the lawyer knows to be represented by another lawyer in the matter, unless the lawyer has the consent of the other lawyer or is authorized to do so by law or a court order.
 This Rule contributes to the proper functioning of the legal system by protecting a person who has chosen to be represented by a lawyer in a matter against possible overreaching by other lawyers who are participating in the matter, interference by those lawyers with the lawyer-client relationship, and the uncounseled disclosure of information relating to the representation.
 This Rule does not prohibit communication with a represented person, or an employee or agent of such a person, concerning matters outside the representation. For example, the existence of a controversy between a government agency and a private party, or between two organizations, does not prohibit a lawyer for either from communicating with nonlawyer representatives of the other regarding a separate matter. Nor does this Rule preclude communication with a represented person who is seeking advice from a lawyer who is not otherwise representing a client in the matter. A lawyer may not make a communication prohibited by this Rule through the acts of another. See Rule 8.4(a). Parties to a matter may communicate directly with each other, and a lawyer is not prohibited from advising a client concerning a communication that the client is legally entitled to make. Also, a lawyer having independent justification or legal authorization for communicating with a represented person is permitted to do so.
 Communications authorized by law may include communications by a lawyer on behalf of a client who is exercising a constitutional or other legal right to communicate with the government. Communications authorized by law may also include investigative activities of lawyers representing governmental entities, directly or through investigative agents, prior to the commencement of criminal or civil enforcement proceedings. When communicating with the accused in a criminal matter, a government lawyer must comply with this Rule in addition to honoring the constitutional rights of the accused. The fact that a communication does not violate a state or federal constitutional right is insufficient to establish that the communication is permissible under this Rule.
 A lawyer who is uncertain whether a communication with a represented person is permissible may seek a court order. A lawyer may also seek a court order in exceptional circumstances to authorize a communication that would otherwise be prohibited by this Rule, for example, where communication with a person represented by counsel is necessary to avoid reasonably certain injury.
 This Rule also applies to communications with any person, whether or not a party to a formal adjudicative proceeding, contract, or negotiation, who is represented by counsel concerning the matter to which the communication relates.
 In the case of a represented organization, this Rule prohibits communications with a constituent of the organization who supervises, directs, or regularly consults with the organization's lawyer concerning the matter or who has authority to obligate the organization with respect to the matter or whose act or omission in connection with the matter may be imputed to the organization for purposes of civil or criminal liability. If a constituent of the organization is represented in the matter by his or her own counsel, the consent by that counsel to a communication will be sufficient for purposes of this Rule. Compare Rule 3.4(f). The prohibition of this Rule does not apply to contact with an unrepresented former constituent of the represented organization (although Rule 4.3 does then apply); however, the lawyer making the contact must take care not to seek to induce the former constituent to reveal information that may be protected by the privilege attached to lawyer-client communications to the extent of the person's contacts, while a constituent, with her or his former employer's counsel.
 The prohibition on communications with a represented person only applies, however, in circumstances where the lawyer knows that the person is in fact represented in the matter to be discussed. This means that the lawyer has actual knowledge of the fact of the representation; but such actual knowledge may be inferred from the circumstances. See Rule 1.0(g). Thus, a lawyer cannot evade the requirement of obtaining the consent of counsel by closing eyes to the obvious.
 This Rule applies even though the represented person initiates or consents to the communication. A lawyer must immediately terminate communication with a person if, after commencing communication, the lawyer learns that the person is one with whom communication is not permitted by this Rule.
 In the event the person with whom the lawyer communicates is not known to be represented by counsel in the matter, the lawyer's communications are subject to Rule 4.3.
