Paragraph 2
A member of an advisory body, other than its chair, is to hold and vacate office in accordance with the written terms of the appointment (but this is subject to sub-paragraphs (2) and (3)).
The term of an appointment may not exceed four years (but an appointment may be renewed).
A member of an advisory body may resign from it at any time by notice in writing to the Ministers.
Where a person ceases to be a member of an advisory body, the person also ceases to be a member of any expert advisory group appointed by the advisory body (including an expert advisory group appointed jointly with the other advisory body).
But sub-paragraph (4) does not apply if—
the person was a member of the advisory body only by virtue of being co-opted under regulation 13; or
the person is immediately re-appointed to the advisory body.
