Upon filing of any appeal proceeding before the applicable Zoning Hearing Board and during its pendency before the applicable Board, all land development pursuant to any challenged ordinance, order or approval of the applicable Zoning Officer or of any agency or body, and all official action thereunder, shall be stayed unless the applicable Zoning Officer or any other appropriate agency or body certifies to the applicable Board facts indicating that such stay would cause imminent peril to life or lot, in which case the development or official action shall not be stayed otherwise than by a restraining order, which may be granted by the applicable Board or by the court having jurisdiction of zoning appeals, on petition, after notice to the applicable Zoning Officer or other appropriate agency or body. When an application for development, preliminary or final, has been duly approved and proceedings designed to reverse or limit the approval are filed with the applicable Board by persons other than the applicant, the applicant may petition the court having jurisdiction of zoning appeals to order such persons to post bond as a condition to continuing the proceedings before the applicable Board.
