Any person who is compelled or requested to furnish testimony, documentary evidence, or other information with respect to any matter under formal investigation shall, on request, be shown the order initiating the investigation.

Any person who, in a formal investigation, is compelled to appear and testify, or who appears and testifies by request or permission of the Comptroller, may be accompanied, represented, and advised by counsel. The right to be accompanied, represented, and advised by counsel means the right of a person testifying to have an attorney present at all times while testifying and to have the attorney—

Advise the person before, during and after the conclusion of testimony;

Question the person briefly at the conclusion of testimony to clarify any of the answers given; and

Make summary notes during the testimony solely for the use of the person.

Any person who has given or will give testimony and counsel representing the person may be excluded from the proceedings during the taking of testimony of any other witness.

Any person who is compelled to give testimony is entitled to inspect any transcript that has been made of the testimony but may not obtain a copy if the Comptroller's representatives conducting the proceedings have cause to believe that the contents should not be disclosed pending completion of the investigation.

Any designated representative conducting an investigative proceeding shall report to the Comptroller any instances where a person has been guilty of dilatory, obstructionist or insubordinate conduct during the course of the proceeding or any other instance involving a violation of this part. The Comptroller may take such action as the circumstances warrant, including exclusion of the offending individual or individuals from participation in the proceedings.
