Discontinuing an action/abandoning an application – presumptive rules on costs
A civil action can be ended by the plaintiff by filing a notice of discontinuance. An applicant can end an application by filing a notice of abandonment. The steps can be taken by a plaintiff or applicant at any time. However, anyone who has been served with the claim or application, and who has responded to it, can ask the court to award them costs as compensation for the costs they incurred in responding to the proceeding.
