Bernheim has represented respondent essentially throughout this litigation. Bernheim was formerly a partner in the firm of Senneff, Bernheim, Emery & Kelly, but during the course of these proceedings became a partner of Gack in the firm of James, Gack, Bernheim & Freeman. On May 7, 1992, appellant discovered Bernheim’s association with Gack, and subsequently asked Bernheim to withdraw as respondent’s attorney because of “confidential information” previously imparted by appellant to Gack. Bernheim declined to withdraw from the case, citing the absence of any previous “confidential communications” between appellant and Gack. On May 22, 1992, a substitution of counsel was filed, which formally indicated Bernheim’s association with the law firm of James, Gack, Bernheim & Freeman, and prompted appellant’s motion for disqualification of counsel.
Appellant argues that the trial court erred in denying her motion to disqualify Bernheim as respondent’s counsel. She insists that her prior consultation with Gack has a “substantial relationship” to the present controversy and precludes Bernheim, who is now in partnership with Gack, from currently representing respondent.
Our review of appellant’s motion to disqualify respondent’s counsel is constrained by the principle that reversal may be predicated only upon a showing of abuse of the trial court’s discretion. (In re Complex Asbestos Litigation (1991) 232 Cal.App.3d 572, 585 [283 Cal.Rptr. 732]; Western Continental Operating Co. v. Natural Gas Corp. (1989) 212 Cal.App.3d 752, 758 [261 Cal.Rptr. 100]; Klein v. Superior Court (1988) 198 Cal.App.3d 894, 908 [244 Cal.Rptr. 226].) In exercising discretion, the trial court is required to make a reasoned judgment which complies with applicable legal principles and policies. (Henriksen v. Great American Savings & Loan (1992) 11 Cal.App.4th 109, 113 [14 Cal.Rptr.2d 184]; In re Complex Asbestos Litigation, supra, at p. 585; Gregori v. Bank of America (1989) 207 Cal.App.3d 291, 300 [254 Cal.Rptr. 853].) “Discretion will thus be deemed to have been abused if the trial court fails to exercise discretion where such exercise is required. [Citation.]” (Henriksen v. Great American Savings & Loan, supra, at p. 113; see also Truck Ins. Exchange v. Fireman’s Fund Ins. Co. (1992) 6 Cal.App.4th 1050, 1055 [8 Cal.Rptr.2d 228].)
We are also bound in our reviewing function by the substantial evidence rule. (In re Complex Asbestos Litigation, supra, 232 Cal.App.3d at p. 585; Higdon v. Superior Court (1991) 227 Cal.App.3d 1667, 1671 [278 Cal.Rptr. 588].) Thus, if substantial evidence supports the trial court’s express or implied findings of fact, we review the resulting legal conclusions for an abuse of discretion. (Ibid.) The judgment of the trial court is presumed correct; all intendments and presumptions are indulged to support the judgment; conflicts in the declarations must be resolved in favor of the prevailing
