The plaintiffs, in another maneuver in the federal court, sought to vacate and set aside the second notice of dismissal. That motion is pending. Plaintiffs contend that because the federal court has not ruled on this motion the Routt County District Court “could not properly determine any federal dismissal.”
In this connection, the order of the federal court, dated April 22, 1965, is most interesting, since that court was likewise confronted with the effect of the “double dismissal” rule. After reviewing the contentions of the respective parties, the court, in the preamble of its order, stated, inter alia:
“There appears no necessity for the law of Colorado to be determined secondhand in this particular case, for in the pending state action a Colorado court can determine the Colorado law and its application to the case now before it. *
“For the foregoing reasons the Court called counsel into conference and expressed the Court’s feeling that this was a matter in which the doctrine of abstention should be invoked to give the state court an opportunity to determine the question of dismissal or non-dismissal of the state proceedings. Counsel expressed concurrence.” (Emphasis added.)
The change of heart which the plaintiffs evidenced by their attempt to vacate and set aside their second notice of dismissal has no effect, in our opinion, on the efficacy of the dismissal. The notice, upon filing, accomplished the dismissal of the complaint. As pointed out in American Cyanamid Company v. McGhee, supra, the plaintiff
