asked Her Majesty's Government:Whether the Secretary of State or a member of the board of visitors of a prison in England and Wales has ever refused to approve the segregation of a prisoner under Rule 43 for reasons of good order and discipline.

If it seems necessary to segregate a prisoner under Rule 43 in the interests of good order and discipline for longer than 24 hours, responsibility for authorising this rests upon a member of the board of visitors (or the Secretary of State). Segregation may be terminated at any time at the governor's discretion and must be terminated by him on medical advice. Information is not centrally maintained about cases in which approval has been withheld.
