In FSBIC v. Intercapital Corp. of Oregon, 108 Wn.2d 324, 738 P.2d 263 (1987), the Supreme Court of Washington adopted this view, with the following quote: "A motion to disqualify should be made with reasonable promptness after a party discovers the facts which lead to the motion. This court will not allow a litigant to delay filing a motion to disqualify in order to use the motion later as a tool to deprive his opponent of counsel of his choice after substantial preparation of a case has been completed. Central Milk Producers Coop. v. Sentry Food Stores, Inc., 573 F.2d 988, 992 (8th Cir. 1978)."
