The commission shall adopt procedures for the conduct of preliminary reviews and preliminary review hearings. The procedures must include:
(1) a reasonable time for responding to questions submitted by the commission and commission staff and subpoenas issued by the commission; and
(2) the tolling or extension of otherwise applicable deadlines where:
(A) the commission issues a subpoena and the standing preliminary review committee’s meeting schedule makes it impossible both to provide a reasonable time for response and to comply with the otherwise applicable deadlines; or
(B) the commission determines that, despite the standing preliminary review committee’s diligence and the reasonable cooperation of the respondent, a matter is too complex to resolve within the otherwise applicable deadlines without compromising either the committee’s investigation or the rights of the respondent.
