The master, in addition to the authority conferred on officers to take depositions, shall have the authority to determine all objections to evidence and to exclude evidence that is not within the scope of discovery as defined in Rule 56.01(b).
Upon request of a party, the master shall report a ruling or rulings on evidence to the court either during or after the completion of the taking of a deposition. Within 30 days after being served with a copy of the master's report, any party may file written objections thereto and serve them on the other parties. If objections are filed, the court shall issue an order sustaining or overruling the objections.
