Rules of Professional Conduct: Rule 1.11--Successive Government and Private Employment
(b) If a lawyer is required to decline or to withdraw from employment under paragraph (a) on account of a personal and substantial participation in a matter, no partner or associate of that lawyer, or lawyer with an of counsel relationship to that lawyer, may knowingly accept or continue such employment except as provided in paragraphs (c) and (d) below. The disqualification of such other lawyers does not apply if the sole form of participation was as a judicial law clerk.
(c) The prohibition stated in paragraph (b) shall not apply if the personally disqualified lawyer is timely screened from any form of participation in the matter or representation as the case may be, and from sharing in any fees resulting therefrom, and if the requirements of paragraphs (d) and (e) are satisfied.
(d) Except as provided in paragraph (e), when any of counsel, lawyer, partner, or associate of a lawyer personally disqualified under paragraph (a) accepts employment in connection with a matter giving rise to the personal disqualification, the following notifications shall be required:
(1) The personally disqualified lawyer shall submit to the public department or agency by which the lawyer was formerly employed and serve on each other party to any pertinent proceeding a signed document attesting that during the period of disqualification the personally disqualified lawyer will not participate in any manner in the matter or the representation, will not discuss the matter or the representation with any partner, associate, or of counsel lawyer, and will not share in any fees for the matter or the representation.
(2) At least one affiliated lawyer shall submit to the same department or agency and serve on the same parties a signed document attesting that all affiliated lawyers are aware of the requirement that the personally disqualified lawyer be screened from participating in or discussing the matter or the representation and describing the procedures being taken to screen the personally disqualified lawyer.
(e) If a client requests in writing that the fact and subject matter of a representation subject to paragraph (d) not be disclosed by submitting the signed statements referred to in paragraph (d), such statements shall be prepared concurrently with undertaking the representation and filed with Bar Counsel under seal. If at any time thereafter the fact and subject matter of the representation are disclosed to the public or become a part of the public record, the signed statements previously prepared shall be promptly submitted as required by paragraph (d).
(f) Signed documents filed pursuant to paragraph (d) shall be available to the public, except to the extent that a lawyer submitting a signed document demonstrates to the satisfaction of the public department or agency upon which such documents are served that public disclosure is inconsistent with Rule 1.6 or other applicable law.
(g) This rule applies to any matter involving a specific party or parties.
(h) A lawyer who participates in a program of temporary service to the Office of the District of Columbia Attorney General of the kind described in Rule 1.10(e) shall be treated as having served as a public officer or employee for purposes of paragraph (a), and the provisions of paragraphs (b)-(e) shall apply to the lawyer and to lawyers affiliated with the lawyer.
 This rule deals with lawyers who leave public office and enter other employment. It applies to judges and their law clerks as well as to lawyers who act in other capacities. It is a counterpart of Rule 1.9, as applied to an individual former government lawyer, and of Rule 1.10, as applied to a law firm.
 A lawyer representing a government agency, whether employed or specially retained by the government, is subject to the Rules of Professional Conduct, including the prohibition against representing adverse interests stated in Rule 1.7 and the protections afforded former clients in Rule 1.9. In addition, such a lawyer is subject to this Rule 1.11 and to statutes and government regulations concerning conflict of interest. In the District of Columbia, where there are many lawyers for the federal and D.C. governments and their agencies, a number of whom are constantly leaving government and accepting other employment, particular heed must be paid to the federal conflict-of-interest statutes.See, e.g.,18 U.S.C. Chapter 11 and regulations and opinions thereunder.
 Rule 1.11, in paragraph (a), flatly forbids a lawyer to accept other employment in a matter in which the lawyer participated personally and substantially as a public officer or employee; participation specifically includes acting on a matter in a judicial capacity. Other than as noted in Comment  to this rule, there is no provision for waiver of the individual lawyer’s disqualification. “Matter” is defined in paragraph (g) so as to encompass only matters that are particular to a specific party or parties. The making of rules of general applicability and the establishment of general policy will ordinarily not be a “matter” within the meaning of Rule 1.11. When a lawyer is forbidden by paragraph (a) to accept private employment in a matter, the partners and associates of that lawyer are likewise forbidden, by paragraph (b), to accept the employment unless the screening and disclosure procedures described in paragraphs (c) through (f) are followed.
 The rule forbids lawyers to accept other employment in connection with matters that are the same as or “substantially related” to matters in which they participated personally and substantially while serving as public officers or employees. The leading case defining “substantially related” matters in the context of former government employment is Brown v. District of Columbia Board of Zoning Adjustment, 486 A.2d 37 (D.C. 1984) (en banc). There the D.C. Court of Appeals,en banc,held that in the “revolving door” context, a showing that a reasonable person could infer that, through participation in one matter as a public officer or employee, the former government lawyer “may have had access to information legally relevant to, or otherwise useful in” a subsequent representation, is prima facie evidence that the two matters are substantially related. If this prima facie showing is made, the former government lawyer must disprove any ethical impropriety by showing that the lawyer “could not have gained access to information during the first representation that might be useful in the later representation.” Id. at 49-50. In Brown, the Court of Appeals announced the “substantially related” test after concluding that, under former DR 9-101(B), see“ Revolving Door,” 445 A.2d 615 (D.C. 1982) (en banc) (per curiam), the term “matter” was intended to embrace all matters “substantially related” to one another – a test that originated in Aside-switching@ litigation between private parties. See Rule 1.9, Comments  and ; Brown, 486 A.2d at 39-40 n. 1, 41-42 & n. 4. Accordingly, the words “or substantially related to” in paragraph (a) are an express statement of the judicial gloss in Brown interpreting “matter.”
 Paragraph (a)’s absolute disqualification of a lawyer from matters in which the lawyer participated personally and substantially carries forward a policy of avoiding both actual impropriety and the appearance of impropriety that is expressed in the federal conflict-of-interest statutes and was expressed in the former Code of Professional Responsibility. Paragraph (c) requires the screening of a disqualified lawyer from such a matter as a condition to allowing any lawyers in the disqualified lawyer’s firm to participate in it. This procedure is permitted in order to avoid imposing a serious deterrent to lawyers’ entering public service. Governments have found that they benefit from having in their service both younger and more experienced lawyers who do not intend to devote their entire careers to public service. Some lawyers might not enter into short-term public service if they thought that, as a result of their active governmental practice, a firm would hesitate to hire them because of a concern that the entire firm would be disqualified from matters as a result.
 There is no imputed disqualification and consequently no screening requirement in the case of a judicial law clerk. But such clerks are subject to a personal obligation not to participate in matters falling within paragraph (a), since participation by a law clerk is within the term “judicial or other adjudicative capacity.”
 Paragraph (d) imposes a further requirement that must be met before lawyers affiliated with a disqualified lawyer may participate in the representation. Except to the extent that the exception in paragraph (e) is satisfied, both the personally disqualified lawyer and at least one affiliated lawyer must submit to the agency signed documents basically stating that the personally disqualified lawyer will be screened from participation in the matter. The personally disqualified lawyer must also state that the lawyer will not share in any fees paid for the representation in question. And the affiliated lawyer must describe the procedures to be followed to ensure that the personally disqualified lawyer is effectively screened.
 Paragraph (e) makes it clear that the lawyer’s duty, under Rule 1.6, to maintain client confidences and secrets may preclude the submission of any notice required by paragraph (d). If the client requests in writing that the fact and subject matter of the representation not be disclosed, the lawyer must comply with that request. If the client makes such a request, the lawyer must abide by the client’s wishes until such time as the fact and subject matter of the representation become public through some other means, such as a public filing. Filing a pleading or making an appearance in a proceeding before a tribunal constitutes a public filing. Once information concerning the representation is public, the notifications called for must be made promptly, and the lawyers involved may not honor a client request not to make the notifications. If a government agency has adopted rules governing practice before the agency by former government employees, members of the District of Columbia Bar are not exempted by Rule 1.11(e) from any additional or more restrictive notice requirements that the agency may impose. Thus the agency may require filing of notifications whether or not a client consents. While the lawyer cannot file a notification that the client has directed the lawyer not to file, the failure to file in accordance with agency rules may preclude the lawyer’s representation of the client before the agency. Such issues are governed by the agency’s rules, and Rule 1.11(e) is not intended to displace such agency requirements.
 Although paragraph (e) prohibits the lawyer from disclosing the fact and subject matter of the representation when the client has requested in writing that the information be kept confidential, the paragraph requires the lawyer to prepare the documents described in paragraph (d) as soon as the representation commences and to preserve the documents for possible submission to the agency and parties to any pertinent proceeding if and when the client does consent to their submission or the information becomes public.
 “Other employment,” as used in paragraph (a) of this rule, includes the representation of a governmental body other than an agency of the government by which the lawyer was employed as a public officer or employee, but in the case of a move from one government agency to another the prohibition provided in paragraph (a) may be waived by the government agency with which the lawyer was previously employed. As used in paragraph (a), it would not be other employment for a lawyer who has left the employment of a particular government agency and taken employment with another government agency (e.g., the Department of Justice) or with a private law firm to continue or accept representation of the same government agency with which the lawyer was previously employed.
 Paragraph (c) does not prohibit a lawyer from receiving a salary or partnership share established by prior independent agreement. It prohibits directly relating the attorney’s compensation in any way to the fee in the matter in which the lawyer is disqualified. See D.C. Bar Legal Ethics Committee Opinion 279.
 Rule 1.10(e) provides an exception to the general imputation imposed by Rule 1.10(a) for lawyers assisting the Office of the District of Columbia Attorney General on a temporary basis. Rule 1.10(e) provides that lawyers providing such temporary assistance are not considered to be affiliated with their law firm during such periods of temporary assistance. However, lawyers participating in such temporary assistance programs have a potential for conflicts of interest or the abuse of information obtained while participating in such programs. It is appropriate to subject lawyers participating in temporary assistance programs to the same rules which paragraphs (a)-(g) impose on former government employees. Paragraph (h) effects this result.
 In addition to ethical concerns, provisions of conflict of interest statutes or regulations may impose limitations on the conduct of lawyers while they are providing assistance to the Office of the District of Columbia Attorney or after they return from such assignments. See, e.g., 18 U.S.C. §' 207, 208. Compliance with the Rules of Professional Conduct does not necessarily constitute compliance with all of the obligations imposed by conflict of interest statutes or regulations.
