Rule 3.7.Lawyer as Witness 
 (a)A lawyer shall not act as advocate at a trial in which the 
 lawyer is likely to be a necessary witness except where: 
  
 (1)the testimony relates to an uncontested issue; 
  
 (2)the testimony relates to the nature and value of legal 
 services rendered in the case; or 
  
 (3)disqualification of the lawyer would work substantial 
 hardship on the client. 
  
 (b)A lawyer shall not act as advocate in a trial in which 
 another lawyer in the lawyer's firm is likely to be called as a witness 
 unless the requirements of Rule 1.7 or Rule 1.9 have been met. 
  
 
                                                                
ANNOTATIONS
COMMENT [1]Combining the roles of advocate and witness can involve a conflict of interest between the lawyer and client and can prejudice the opposing party. If a lawyer is both counsel and witness, the lawyer becomes more easily impeachable for interest and thus may be a less effective witness. Conversely, the opposing counsel may be handicapped in challenging the credibility of the lawyer when the lawyer also appears as an advocate in the case. An advocate who becomes a witness is in the unseemly and ineffective position of arguing his or her own credibility. [2]The opposing party has proper objection where the combination of roles may prejudice that party's rights in the litigation. A witness is required to testify on the basis of personal knowledge, while an advocate is expected to explain and comment on evidence given by others. It may not be clear whether a statement by an advocate-witness should be taken as proof or as an analysis of the proof. [3]Paragraph (a)(1) recognizes that if the testimony will be uncontested, the ambiguities in the dual role are purely theoretical. Paragraph (a)(2) recognizes that where the testimony concerns the extent and value of legal services rendered in the action in which the testimony is offered, permitting the lawyers to testify avoids the need for a second trial with new counsel to resolve that issue. Moreover, in such a situation the judge has first hand knowledge of the matter in issue; hence, there is less dependence on the adversary process to test the credibility of the testimony. [4]Apart from these two exceptions, paragraph (a)(3) recognizes that a balancing is required between the interests of the client and those of the opposing party. Whether the opposing party is likely to suffer prejudice depends on the nature of the case, the importance and probable tenor of the lawyer's testimony, and the probability that the lawyer's testimony will conflict with that of other witnesses. Even if there is risk of such prejudice, in determining whether the lawyer should be disqualified due regard must be given to the effect of disqualification on the lawyer's client. It is relevant that one or both parties could reasonably foresee that the lawyer would probably be a witness. [5]Whether the combination of roles involves an improper conflict of interest with respect to the client is determined by Rule 1.7 or 1.9. For example, if there is likely to be substantial conflict between the testimony of the client and that of the lawyer or member of the lawyer's firm, the representation is improper. The problem can arise whether the lawyer is called as a witness on behalf of the client or is called by the opposing party. Determining whether or not such a conflict exists is primarily the responsibility of the lawyer involved. See Comment to Rule 1.7. If a lawyer who is a member of a firm may not act as both advocate and witness by reason of conflict of interest Rule 1.10 disqualifies the firm also. COMMITTEE COMMENT The Committee disagreed with the approach taken in section (b) of the Model Rules version of Rule 3.7 which stated that a lawyer could act as an advocate, even if another lawyer in the advocate's firm was going to testify, unless precluded by either Rule 1.7 or Rule 1.9. In such a situation, a lawyer is not required to argue his or her own credibility to the fact-finder. But there is still a potential conflict of interest which can be serious in such situations. For example, it may be that the firm relationship between the advocate-lawyer and the witness-lawyer may make the witness seem less credible to the jury. The Committee felt that (b) of 3.7 did not give sufficient emphasis to the conflicts of interest that can arise in such situations. Thus the Committee changed the emphasis in (b) considerably to state that a lawyer shall not act as an advocate in such a situation unless the lawyer first complies with the requirements of Rules 1.7 or 1.9. ANNOTATION Law reviews. For Formal Opinion No. 78 of the CBA Ethics Committee, "Disqualification of the Advocate/Witness", see 23 Colo. Law. 2087 (1994). Annotator's note. Rule 3.7 is similar to DR 5-101 and DR 5-102 as they existed prior to the 1992 repeal and reenactment of the Code of Professional Responsibility. Relevant cases construing those provisions have been included in the annotations to Rule 1.7. A party seeking disqualification of any attorney as "likely to be a necessary witness" must show that "the advocate's testimony is necessary, and not merely cumulative". Religious Technology Center v. F.A.C.T. Net, Inc., 945 F. Supp. 1470 (D. Colo. 1996). This rule does not mandate a hearing where there is a possibility of a conflict of interest on the part of an attorney called as a witness against his or her client. Taylor v. Grogan, 900 P.2d 60 (Colo. 1995).
