When the testimony has been fully transcribed, the transcript shall be submitted to the deponent for inspection and for signing and shall be read to or by the deponent and shall be signed, unless the inspection, reading, and signing are waived by the deponent, or the deponent is ill, or the deponent cannot be found, or the deponent refuses to sign. Any changes in form or substance that the deponent desires to make shall be entered upon the transcript, which shall be signed by the deponent. If the transcript is not signed by the deponent within ten days from the date of its submission to the deponent, the reporter who took the deposition shall certify the transcript in the usual form and state on the record the fact of the waiver, of the illness or absence of the deponent, or the refusal to sign together with the reason, if any, given therefor. The transcript may then be used as fully as though signed, unless the Hearing Committee to which the deposition is tendered holds that the reasons given for the refusal to sign require rejection of the deposition testimony in whole or in part.
