History
Source: Entire Appendix repealed and readopted April 12, 2007, effective January 1, 2008; (b) and Comment [2] amended and effective July 11, 2012. COMMENT [1] Many forms of improper influence upon a tribunal are proscribed by criminal law. Oth- ers are specified in the Colorado Code of Judi- cial Conduct, with which an advocate should be familiar. A lawyer is required to avoid contrib- uting to a violation of such provisions. [2] During a proceeding a lawyer may not communicate ex parte with persons serving in an official capacity in the proceeding, such as judges, masters or jurors, subject to two excep- tions: (1) when a law or court order authorizes the lawyer to engage in the communication, and (2) when a judge initiates an ex parte commu- nication with the lawyer and the lawyer reason- ably believes that the subject matter of the com- munication is within the scope of the judge’s authority to engage in the communication under a rule of judicial conduct. Examples of ex parte communications authorized under the first ex- ception are restraining orders, submissions made in camera by order of the judge, and applications for search warrants and wiretaps. See also Cmt. [5]. Colo. RPC 4.2 (discussing communications authorized by law or court or- der with persons represented by counsel in a matter). With respect to the second exception, Rule 2.9(A)(1) of the Colorado Code of Judicial Conduct, for example, permits judges to engage in ex parte communications for scheduling, ad- ministrative, or emergency purposes not involv- ing substantive matters, but only if ‘‘circum- stances require it,’’ ‘‘the judge reasonably believes that no party will gain a procedural, substantive, or tactical advantage as a result of the ex parte communication,’’ and ‘‘the judge makes provision promptly to notify all other parties of the substance of the ex parte commu- nication, and gives the parties an opportunity to respond.’’ Code of Jud. Conduct, Rule 2.9(A)(1). See also Code of Judicial Conduct for United States Judges, Canon 3(A)(4)(b)(‘‘A judge may. . . (b) when circumstances require it, permit ex parte communication for schedul- ing, administrative, or emergency purposes, but only if the ex parte communication does not address substantive matters and the judge rea- sonably believes that no party will gain a pro- cedural, substantive, or tactical advantage as a result of the ex parte communication[.]’’). The second exception does not authorize the lawyer to initiate such a communication. However, a judge will be deemed to have initiated a com- munication for purposes of this Rule if the judge or the court maintains a regular practice of allowing or requiring lawyers to contact the judge for administrative matters such as sched- uling a hearing and the lawyer communicates in compliance with that practice. When a judge initiates a communication, the lawyer must dis- continue the communication if it exceeds the judge’s authority under the applicable rule of judicial conduct. For example, if a judge prop- erly communicates ex parte with a lawyer about the scheduling of a hearing, pursuant to Rule 2.9(A)(1) of the Colorado Code of Judicial Conduct, but proceeds to discuss substantive matters, the lawyer has an obligation to discon- tinue the communication. [3] A lawyer may on occasion want to com- municate with a juror or prospective juror after the jury has been discharged. The lawyer may do so unless the communication is prohibited by law or a court order but must respect the desire of the juror not to talk with the lawyer. The lawyer may not engage in improper con- duct during the communication. [4] The advocate’s function is to present evidence and argument so that the cause may be decided according to law. Refraining from abu- sive or obstreperous conduct is a corollary of the advocate’s right to speak on behalf of liti- gants. A lawyer may stand firm against abuse by a judge but should avoid reciprocation; the judge’s default is no justification for similar dereliction by an advocate. An advocate can present the cause, protect the record for subse- quent review and preserve professional integrity by patient firmness no less effectively than by belligerence or theatrics. [5] The duty to refrain from disruptive con- duct applies to any proceeding of a tribunal, including a deposition. See Rule 1.0(m). ANNOTATION Law reviews. For article, ‘‘Ex Parte Commu- nications with a Tribunal: From Both Sides’’, see 29 Colo. Law. 55 (Apr. 2000). Annotator’s note. Rule 3.5 is similar to DR 7-101, DR 7-106, DR 7-108, DR 7-109, DR 7-110, and DR 8-101 as they existed prior to the 1992 repeal and reenactment of the code of professional responsibility. Relevant cases con- struing DR 7-108, DR 7-109, DR 7-100, and DR 8-101 have been included in the annotations to this rule. Cases construing DR 7-101 have been included under Rule 1.2 and cases constru- ing DR 7-106 have been included under Rule 3.3. Conduct violating this rule in conjunction with other disciplinary rules is sufficient to justify suspension for one year and one day. People v. Brennan, 240 P.3d 887 (Colo. O.P .D.J. 2009). Conduct violating this rule in conjunction with other disciplinary rules is sufficient to justify suspension. People v. Maynard, 238 P.3d 672 (Colo. O.P .D.J. 2009). Cases Decided Under Former DR 7-108. Jury tampering is basis for indefinite sus- pension of attorney. People v. Radinsky, 176 Colo. 357, 490 P.2d 951 (1971). Cases Decided Under Former DR 7-109. Evidence sufficient to justify suspension from the practice of law. People v. Belfor, 197 Colo. 223, 591 P.2d 585 (1979). Cases Decided Under Former DR 7-110. Suggesting that witness contact chief jus- tice for attorney’s benefit justifies public cen- sure. Where an attorney suggested to a princi- pal witness in a pending grievance proceeding against that attorney that he write a letter on behalf of the attorney to the chief justice of the state supreme court, substantially recanting his testimony in the grievance proceeding, the at- torney’s conduct violated the code of profes- sional responsibility and C.R.C.P. 241.6. Public censure is the appropriate discipline for this breach of professional obligations. People v. Hertz, 638 P.2d 794 (Colo. 1982). The imposition of a one-year suspension in Illinois for the loaning of money to a judge warrants imposition of the same sanction in Colorado. People v. Chatz, 788 P.2d 157 (1990). Conduct violating this rule in conjunction with other disciplinary rules is sufficient to justify disbarment. People v. Bannister, 814 P.2d 801 (Colo. 1991). Cases Decided Under Former DR 8-101. District attorney not tribunal. It is not the intent of paragraph (A)(2) to treat a district attorney or those acting under him as a tribunal. People ex rel. Gallagher v. Hertz, 198 Colo. 522, 608 P.2d 335 (1979).
