17 C.F.R. § 33.6
The Commission may, after notice and opportunity for a hearing on the record, suspend or revoke the designation of any board of trade as a contract market in a commodity option for which it is designated if the Commission determines that:
(d) Option trading on the contract market in that contract is contrary to the protection of option customers or the underlying futures or cash markets, or is otherwise contrary to the public interest: Provided, That pending completion of any proceeding under this section, the Commission may suspend such designation for the duration of the proceedings, if in the Commission's judgment, the continuation of such trading presents a substantial risk to the public interest.
