204 Pa. Code § 91.17
No part of a deposition shall constitute a part of the record in the proceeding, unless offered in evidence before the hearing committee or special master. At the hearing, any part or all of a deposition, so far as admissible under the rules of evidence applied as though the witness were then present and testifying, may be used against any participant who was present or represented at the taking of the deposition or who had notice thereof. If only part of a deposition is offered in evidence by a participant, a participant with an adverse interest may require the offering participant to introduce any other part which ought in fairness to be considered with the part introduced, and any participant may introduce any other parts. The introduction in evidence of the deposition or any part thereof for any purpose other than contradicting or impeaching the deponent, makes the deponent the witness of the party introducing the deposition.
