(a) During the course of representing a client, a lawyer shall not communicate or cause another to communicate about the subject of the representation with a party known to be represented by another lawyer in the matter, unless the lawyer has the prior consent of the lawyer representing such other party or is authorized by law to do so.
(b) During the course of representing a client, a lawyer may communicate about the subject of the representation with a nonparty employee of the opposing party without obtaining the consent of that party’s lawyer. However, prior to communicating with any such nonparty employee, a lawyer must disclose to such employee both the lawyer’s identity and the fact that the lawyer represents a party with a claim against the employee’s employer.
(c) For purposes of this Rule, the term "party" includes any person, including an employee of a party organization, who has the authority to bind a party organization as to the representation to which the communication relates.
(d) This Rule does not prohibit communication by a lawyer with government officials who have the authority to redress the grievances of the lawyer’s client, whether or not those grievances or the lawyer’s communications relate to matters that are the subject of the representation, provided that in the event of such communications the disclosures specified in (b) are made to the government official to whom the communication is made.
 This Rule does not prohibit communication with a party, or an employee or agent of a party, concerning matters outside the representation. For example, the existence of a controversy between two organizations does not prohibit a lawyer for either from communicating with representatives of the other regarding a separate matter. Also, parties to a matter may communicate directly with each other and a lawyer having independent justification for communicating with the other party is permitted to do so.
 In the case of an organization, this Rule prohibits communication by a lawyer for one party concerning the matter in representation with persons having the power to bind the organization as to the particular representation to which the communication relates. If an agent or employee of the organization with authority to make binding decisions regarding the representation is represented in the matter by separate counsel, the consent by that agent’s or employee’s counsel to a communication will be sufficient for purposes of this Rule.
 The Rule does not prohibit a lawyer from communicating with employees of an organization who have the authority to bind the organization with respect to the matters underlying the representation if they do not also have authority to make binding decisions regarding the representation itself. A lawyer may therefore communicate with such persons without first notifying the organization’s lawyer. See D.C. Bar Legal Ethics Committee Opinion No. 129 (1983). But before communicating with such a "nonparty employee," the lawyer must disclose to the employee the lawyer’s identity and the fact that the lawyer represents a party with a claim against the employer. It is preferable that this disclosure be made in writing. The notification requirements of Rule 4.2(b) apply to contacts with government employees who do not have the authority to make binding decisions regarding the representation.
 This Rule also covers any person, whether or not a party to a formal proceeding, who is represented by counsel concerning the matter in question.
 This Rule does not apply to the situation in which a lawyer contacts employees of an organization for the purpose of obtaining information generally available to the public, or obtainable under the Freedom of Information Act, even if the information in question is related to the representation. For example, a lawyer for a plaintiff who has filed suit against an organization represented by a lawyer may telephone the organization to request a copy of a press release regarding the representation, without disclosing the lawyer’s identity, obtaining the consent of the organization’s lawyer, or otherwise acting as paragraphs (a) and (b) of this Rule require.
 Paragraph (d) recognizes that special considerations come into play when a lawyer is seeking to redress grievances involving the government. It permits communications with those in government having the authority to redress such grievances (but not with any other government personnel) without the prior consent of the lawyer representing the government in such cases. However, a lawyer making such a communication without the prior consent of the lawyer representing the government must make the kinds of disclosures that are required by paragraph (b) in the case of communications with non-party employees.
 Paragraph (d) does not permit a lawyer to bypass counsel representing the government on every issue that may arise in the course of disputes with the government. It is intended to provide lawyers access to decision makers in government with respect to genuine grievances, such as to present the view that the government’s basic policy position with respect to a dispute is faulty, or that government personnel are conducting themselves improperly with respect to aspects of the dispute. It is not intended to provide direct access on routine disputes such as ordinary discovery disputes, extensions of time or other scheduling matters, or similar routine aspects of the resolution of disputes.
 This Rule is not intended to enlarge or restrict the law enforcement activities of the United States or the District of Columbia which are authorized and permissible under the Constitution and law of the United States or the District of Columbia. The "authorized by law" proviso to Rule 4.2(a) is intended to permit government conduct that is valid under this law. The proviso is not intended to freeze any particular substantive law, but is meant to accommodate substantive law as it may develop over time.
