"When a mental health review tribunal has ordered the discharge of a patient, is it lawful to readmit him under section 2 or section 3 of the [Mental Health Act 1983 ] where it cannot be demonstrated that there has been a relevant change of circumstances?"
"that there is no sense in which those concerned in a section 3 application are at any stage bound by an earlier tribunal decision. The doctors, social worker, and managers must, under the statute, exercise their independent judgment, whether or not there is an extant tribunal decision relating to the patient."
"Powers of tribunals 72 - (1) Where application is made to a Mental Health Review Tribunal by or in respect of a patient who is liable to be detained under this Act, the tribunal may in any case direct that the patient be discharged, and - (a) the tribunal shall direct the discharge of a patient liable to be detained under section 2 above if they are satisfied - (i) that he is not then suffering from mental disorder or from mental disorder of a nature or degree which warrants his detention in a hospital for assessment (or for assessment followed by medical treatment) for at least a limited period; or (ii) that his detention as aforesaid is not justified in the interests of his own health or safety or with a view to the protection of other persons; (b) the tribunal shall direct the discharge of a patient liable to be detained otherwise than under section 2 above if they are satisfied - (i) that he is not then suffering from mental illness, psychopathic disorder, severe mental impairment or mental impairment or from any of those forms of disorder of a nature or degree which makes it appropriate for him to be liable to be detained in a hospital for medical treatment; or (ii) that it is not necessary for the health or safety of the patient or for the protection of other persons that he should receive such treatment; or (iii) in the case of an application by virtue of paragraph (g) of section 66(1) above, that the patient, if released, would not be likely to act in a manner dangerous to other persons or to himself."
"It must also be observed that in the field of mental illness the assessment as to whether the disappearance of the symptoms of the illness is confirmation of complete recovery is not an exact science." (2) As the Master of the Rolls pointed out in paragraph 30 of his judgment quoted above, the condition of many of those suffering from mental disorder will not be static. Episodes of acute illness may be followed by episodes of remission. Thus it does not follow that a tribunal decision, however sound when made, will remain so. Other things being equal, the longer the period since the decision was made the greater the chance that the patient's mental condition may have altered, whether for better or worse. (3) It is plain from the language of sub-paragraphs (a)(i) and (b)(i) of section 72(1), quoted above, that the focus of the tribunal's enquiry into the mental health of the patient is on whether he is not "then suffering" from mental disorder or mental illness.
