When the sureties, or either of them, are objected to, the surety or sureties so objected shall justify before the court out of which the execution issued, upon ten days’ notice of the time so justify being given to the judgment creditor or his 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 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 case of the first undertaking filed and served.
