In Earl Scheib, Inc. v. Superior Court (1967) 253 Cal.App.2d 703, the trial court had denied a similar motion on the ground that it was "filed too late," with prejudice to the adversary party. The appellate court, commenting (p. 707) upon the "'most sacred and confidential relationship'" involved, stated: "It seems clear to us from our review of the cases discussed above that a client or former client of an attorney can raise the issue of representation of conflicting interests in any one of several ways at any time while the action is pending. " (P. 709.)
