These Rules amend the Prison Rules 1964 (“the 1964 Rules”), as amended. Paragraph 1 of the Schedule makes certain exceptions to the principle that unconvicted prisoners should be kept out of contact with convicted prisoners. Paragraph 2 of the Schedule substitutes a new rule 6 which makes more detailed provision for temporary release of prisoners (which substitution is subject to certain transitional provisions set out in rule 3 of these Rules). Paragraphs 3 and 4 of the Schedule increase the powers of governors in relation to disciplinary offences committed by prisoners (but by virtue of rule 4 of these Rules do not apply in relation to offences committed before the coming into force of these Rules).
