804.6—Procedures for closing meetings, or withholding information, and requests by affected persons to close a meeting.

(a) A meeting shall not be closed, or information pertaining thereto withheld, unless a majority of all Members votes to take such action. A separate vote shall be taken with respect to any action under § 804.5. A single vote is permitted with respect to a series of meetings, a portion or portions of which are proposed to be closed to the public, or with respect to any information concerning such series of meetings, so long as each meeting in such series involves the same particular subject matters and is scheduled to be held no more than thirty days after the initial meeting in such series. Each Member's vote under this paragraph shall be recorded and proxies are not permitted.
(b) Any person whose interest may be directly affected if a portion of a meeting is open may request the Board to close that portion on any of the grounds referred to in § 804.5 (e), (f), or (g). Requests, with reasons in support thereof, should be submitted to the General Counsel, National Transportation Safety Board, 800 Independence Avenue, SW., Washington, DC 20594. On motion of any Member, the Board shall determine by recorded vote whether to grant the request.
