Former Rules of Professional Conduct: Rule 5.1--Responsibilities of a Partner or Supervisory Lawyer
This Rule governed the practice of law in the District of Columbia from January 1, 1991, through January 31, 2007. As of February 1, 2007, the Amended Rules took effect.
(a) A partner in a law firm shall make reasonable efforts to ensure that the firm has in effect measures giving reasonable assurance that all lawyers in the firm conform to the Rules of Professional Conduct.
(b) A lawyer having direct supervisory authority over another lawyer shall make reasonable efforts to ensure that the other lawyer conforms to the Rules of Professional Conduct.
(c) A lawyer shall be responsible for another lawyer’s violation of the Rules of Professional Conduct if:
(1) The lawyer orders or, with knowledge of the specific conduct, ratifies the conduct involved; or
(2) The lawyer has direct supervisory authority over the other lawyer or is a partner in the law firm in which the other lawyer practices, and knows or reasonably should know of the conduct at a time when its consequences can be avoided or mitigated but fails to take reasonable remedial action.
 Paragraphs (a) and (b) refer to lawyers who have supervisory authority over the professional work of a firm or legal department of a government agency. This includes members of a partnership and the shareholders in a law firm organized as a professional corporation; lawyers having supervisory authority in the law department of an enterprise or government agency; and lawyers who have intermediate managerial responsibilities in a firm.
 The measures required to fulfill the responsibility prescribed in paragraphs (a) and (b) can depend on the firm’s structure and the nature of its practice. In a small firm, informal supervision and occasional admonition ordinarily might be sufficient. In a large firm, or in practice situations in which intensely difficult ethical problems frequently arise, more elaborate procedures may be necessary. Some firms, for example, have a procedure whereby junior lawyers can make confidential referral of ethical problems directly to a designated senior partner or special committee. See Rule 5.2. Firms, whether large or small, may also rely on continuing legal education in professional ethics. In any event, the ethical atmosphere of a firm can influence the conduct of all its members and a lawyer having authority over the work of another may not assume that the subordinate lawyer will inevitably conform to the Rules.
 Paragraph (c) sets forth general principles of imputed responsibility for the misconduct of others. Subparagraph (c)(1) makes any lawyer who orders or, with knowledge, ratifies misconduct responsible for that misconduct. See also Rule 8.4(a). Subparagraph (c)(2) extends that responsibility to any lawyer who is a partner in the firm in which the misconduct takes place, or who has direct supervisory authority over the lawyer who engages in misconduct, when the lawyer knows or should reasonably know of the conduct and could intervene to ameliorate its consequences. Whether a lawyer has such supervisory authority in particular circumstances is a question of fact. A lawyer with direct supervisory authority is a lawyer who has an actual supervisory role with respect to directing the conduct of other lawyers in a particular representation. A lawyer who is technically a “supervisor” in organizational terms, but is not involved in directing the effort of other lawyers in a particular representation, is not a supervising lawyer with respect to that representation.
 The existence of actual knowledge is also a question of fact; whether a lawyer should reasonably have known of misconduct by another lawyer in the same firm is an objective standard based on evaluation of all the facts, including the size and organizational structure of the firm, the lawyer’s position and responsibilities within the firm, the type and frequency of contacts between the various lawyers involved, the nature of the misconduct at issue, and the nature of the supervision or other direct responsibility (if any) actually exercised. The mere fact of partnership or a position as a principal in a firm is not sufficient, without more, to satisfy this standard. Similarly, the fact that a lawyer holds a position on the management committee of a firm, or heads a department of the firm, is not sufficient, standing alone, to satisfy this standard.
 Appropriate remedial action would depend on the immediacy of the involvement and the seriousness of the misconduct. The supervisor is required to intervene to prevent avoidable consequences of misconduct if the supervisor knows that the misconduct occurred. Thus, if a supervising lawyer knows that a subordinate misrepresented a matter to an opposing party in a negotiation, the supervisor as well as the subordinate has a duty to correct the resulting misapprehension.
 Professional misconduct by a lawyer under supervision could reveal a violation of paragraph (b) on the part of the supervisory lawyer even though it does not entail a violation of paragraph (c) because there was no direction, ratification, or knowledge of the violation.
 Apart from this Rule and Rule 8.4(a), a lawyer does not have disciplinary liability for the conduct of a partner, associate, or subordinate. Whether a lawyer may be liable civilly or criminally for another lawyer’s conduct is a question of law beyond the scope of these Rules.
