1505.This section gives the Secretary of State power to address any breaches of the duties of co-operation in sections 288 or 290, section 70 of the Health and Social Care Act 2008, or any other enactment which imposes co-operation duties on the bodies listed in subsection (3) of the preceding section. Where the Secretary of State believes that any of those duties has been breached or there is a significant risk that they will be, a written notice of opinion may be issued to the bodies concerned. If the bodies breach or continue to breach the duty following such a notice, the Secretary of State may prohibit each body from exercising certain functions, or exercising them in a certain way, unless the other body in question agrees in writing that they may continue to exercise those functions. In default of such an agreement, the matter may be determined by arbitration. Any prohibition is limited to a period of one year unless the Secretary of State considers the breach is continuing and is having a detrimental effect on the health service; in which case, the period may be extended by one year.
