Rules on Civil Procedure
Section 1. Refusal to answer. - If a party or other deponent refuses to answer any question upon oral examination, the examination may be completed on other matters or adjourned as the proponent of the question may prefer. The proponent may thereafter apply to the proper court of the place where the deposition is being taken, for an order to compel an answer. The same procedure may be availed of when a party or a witness refuses to answer any interrogatory submitted under Rules 23 or 25.
If the application is granted, the court shall require the refusing party or deponent to answer the question or interrogatory and if it also finds that the refusal to answer was without substantial justification, it may require the refusing party or deponent or the counsel advising the refusal, or both of them, to pay the proponent the amount of the reasonable expenses incurred in obtaining the order, including attorney's fees.
If the application is denied and the court finds that it was filed without substantial justification, the court may require the proponent or the counsel advising the filing of the application, or both of them, to pay to the refusing party or deponent the amount of the reasonable expenses incurred in opposing the application, including attorney's fees.
