(a) Depositions taken by the department shall be noticed by issuance and service of a subpoena pursuant to Section 12963.1. If, in the course of the investigation of a complaint, a subpoena is issued and served on an individual or organization not alleged in the complaint to have committed an unlawful practice, written notice of the deposition shall also be mailed by the department to each individual or organization alleged in the complaint to have committed an unlawful practice.

The testimony shall be taken stenographically and transcribed unless the parties agree otherwise. All objections made at the time of the examination shall be noted on the deposition by the person before whom the deposition is taken, and evidence objected to shall be taken subject to the objections.
