“The second question is whether a court may allow withdrawal of a notice of payment in, if between the time when the defendant served his summons seeking leave to withdraw and the hearing of it the plaintiff has given notice of acceptance. The rules do not state that the issue of a summons for leave prevents the plaintiff from giving notice of acceptance. Rule 3(4) does provide that acceptance has the effect of staying the proceedings. I think that it would be most unfortunate if a plaintiff were able to defeat a defendant’s application for leave to withdraw a payment in by giving notice of acceptance before the defendant’s summons could be heard. Since the plaintiff’s acceptance would not have terminated the action, but merely stayed it, I think that the court may notionally remove the stay and proceed to hear the application. A plaintiff’s acceptance does not prevent the court from allowing a defendant to withdraw, but is obviously an important consideration to be taken into account in deciding whether he should be given leave to do so.”
