When the sureties or either of them are objected to, the surety or sureties so objected to shall justify before the Court in which the action is commenced, upon ten days notice of the time when they will so justify being given to the plaintiff, or plaintiff’s attorney. Upon the hearing and examination into the sufficiency of a surety, witnesses may be required to attend and evidence may be procured and introduced in the same manner as in trial of civil cases. Upon such hearing and examination, the Court shall make its order in writing, approving or disapproving the sufficiency of the surety or sureties on such undertaking. In case the court disapproves of the surety or sureties on any undertaking, a new undertaking may be filed and served, and to any undertaking given under the provisions of this Article the same objection to the sureties may be made and the same proceedings had as in the case of the first undertaking filed and served.
