Yes. An appeal can be withdrawn by an appellant at any time prior to the Tribunal making a determination on the matter. If you wish to withdraw your Appeal prior to the hearing date you must write to the RTB stating your wish to do so. However, if the matter is being dealt with by the Tribunal at a hearing, you can tell the Tribunal that you are withdrawing the matter.
Upon being notified of a withdrawal, the Tribunal is required to enquire whether the other party to the dispute objects to the withdrawal and, if so, the Tribunal will sit to decide on any application for costs of the other party against you. In the event that the other party, when notified of the withdrawal, does not object, a Determination Order will be made based on the Adjudicators decision and this will be binding on the parties to the dispute.
