A preliminary objection is only raised to the hearing of the appeal, and not to a few grounds of appeal. The purport of preliminary objection is the termination or truncation of the appeal in limine. A Preliminary Objection should only be filed against the hearing of an appeal and not against one or more grounds of appeal when there are other grounds to sustaining the appeal; which purported Preliminary Objection is, therefore, not capable of truncating the hearing of the appeal. In such a situation, a preliminary objection is not the appropriate procedure to deploy against defective grounds of appeal when there are other grounds, not defective, which can sustain the hearing of the appeal.
