that accommodation or services at any particular health service hospital or hospitals should remain authorised under section 57 or section 58 for use in connection with the treatment of resident or non-resident private patients only while there is a reasonable demand for accommodation and facilities for the private practice of medicine and dentistry in the area or areas served by the hospital or hospitals in question;

that the authorisation of any such accommodation or services under those provisions for use in that connection should be revoked only if sufficient accommodation and facilities for the private practice of medicine and dentistry are otherwise reasonably available (whether privately or at health service hospitals) to meet the reasonable demand for them in the area or areas served by the hospital or hospitals in question;

that the continued authorisation of any such accommodation or services under those provisions for use in that connection should depend on there having been or being taken all reasonable steps to provide, otherwise than at health service hospitals, sufficient reasonable accommodation and facilities for the private practice of medicine and dentistry to meet the reasonable demand for them in the area or areas served by the hospital or hospitals in question;

that failure, in the circumstances mentioned in paragraph (c), to take all reasonable steps that could be taken to provide as mentioned in that paragraph would itself be grounds for the Health Services Board, after giving due warning to persons likely to be affected thereby of the likely consequences of such failure, to propose the revocation of the authorisations under those provisions relating to accommodation or services at the hospital or hospitals in question.
