Ariz. R. Prof'l. Cond. 1.10
Comment [2016 amendment]
. . . .
[5] ER 1.10(b) operates to permit a law firm, under certain circumstances, to represent a person with interests directly adverse to those of a client represented by a lawyer who formerly was associated with the firm. The Rule applies regardless of when the formerly associated lawyer represented the client. However, the law firm may not represent a person with interests adverse to those of a present client of the firm, which would violate ER 1.7. Moreover, the firm may not represent the person where the matter is the same or substantially related to that in which the formerly associated lawyer represented the client and any other lawyer currently in the firm has material information protected by ERs 1.6 and 1.9(c). For purposes of determining whether any current lawyer in the firm has such material information, information maintained by a firm in the form of documents, including electronically stored information, will not be imputed to the remaining lawyers if the firm adopts screening procedures that are reasonably adequate under the circumstances to prevent the remaining lawyers from accessing such information. In determining whether screening procedures are reasonably adequate, factors to be considered include whether technology is available and has been implemented to restrict lawyer access to electronically stored information maintained by the firm and whether adequate notice is provided to lawyers in the firm regarding the screening procedures. Further guidance is provided in ER 1.0, comments [8] - [10]. In addition, the firm should consider whether its lawyers have access to internal electronic databases that utilize research memoranda or other work product from past client representations, to ensure that any protected information is removed from such databases or that access is appropriately restricted.

[9] Rule 1.10(d) removes the imputation otherwise required by ER 1.10(a), but unlike section (c), it does so in some cases without requiring that there be informed consent by the former client. In those cases and in cases where client consent is obtained, the rule requires that the procedures and requirements laid out in sections (d)(3) and (4) be followed. Factors to be considered in determining the adequacy of screening procedures include whether technology is available and has been implemented to restrict lawyer access to electronically stored information maintained by the firm. Other relevant circumstances may include the size of the matter in relation to the overall business of the firm, the number of lawyers in the firm that are actively involved in the matter that is the subject of the screening measures, or other factors that may make it difficult to implement a screen that is reasonably adequate to ensure that protected information is not disclosed, even inadvertently. Additional guidance is provided in ER 1.0, comments [8]-[10]. There may be some circumstances when, taking all factors into account, screening procedures will not be reasonably adequate to guard against inadvertent disclosure of protected information. Lawyers should also be aware that even when screening procedures have been adopted that comply with this Rule, tribunals may consider additional factors in ruling upon motions to disqualify a lawyer from pending litigation.
[10] Paragraph (d)(2) does not prohibit the screened lawyer from receiving a salary or partnership share established by prior independent agreement, but the lawyer may not receive compensation directly related to the matter in which the lawyer is disqualified.
[11] The requirements of ERs 5.1 and 5.3 should be considered in implementing screening procedures under this Rule. If the screened lawyer or the new firm become aware that the screening procedures have been violated or are ineffective, reasonable steps should be taken to remedy the deficiencies and prevent prejudice to the impacted client.
