BARWICK C.J. Marshall v. Watson: The appellant, Peter Marshall, is a member is concerned, he held the rank of senior detective and had been seconded to the special branch of that police force. On 21st July 1967 he received telephone calls which referred to the respondent, Shane Andrew Clark Watson, who is a duly qualified medical practitioner. The appellant thereupon visited the respondent at the Institute of Rheumatology in East Melbourne. After having a conversation with the respondent, the appellant communicated with Dr. Birrell, who is, and for some thirteen and a half years has been, police surgeon for the Victoria Police. The appellant also made some inquiries from people in Sydney. On Sunday, 23rd July, the appellant had a very lengthy conversation with the lady who is now the wife of the respondent. Then on Tuesday, 25th July, the appellant called on the respondent, at the said Institute, in company with Dr. Birrell, after having received a further telephone call from Army Intelligence. Both the appellant and Dr. Birrell listened to what the respondent had to say and asked him questions. Dr. Birrell concluded from what he had seen and heard, that the respondent appeared to be mentally ill and should be admitted for observation into a psychiatric hospital. Being of this opinion, he signed a recommendation, on a form for which the Mental Health Regulations made under the Mental Health Act 1959 (Vict.) provided, which was headed "Medical Recommendation To Accompany Order Or Request For Reception Of A Person As A Patient Into A Psychiatric Hospital". The recommendation conformed to the definition of a recommendation under the Mental Health Act for the particular purpose of s. 42 of that Act. See the definition of "recommendation", s. 3 and ss. 42 (1) and 42 (3). The text of the recommendation was that Dr. Birrell, having personally examined the respondent, recommended that as "he appears to be mentally ill, . . . he should be admitted for observation into a psychiatric hospital". The recommendation contained, as required by the relevant regulation, an account of the facts observed by Dr. Birrell himself and of other facts communicated to him, upon all of which he had formed his opinion as to the mental condition of the respondent. Dr. Birrell produced and gave to the appellant the recommendation and a form of request addressed to the superintendent of the Psychiatric Hospital, Royal Park, that the respondent be received as a patient for observation and treatment into that hospital. The appellant signed the request. Dr. Birrell instructed the appellant to take the respondent to that hospital for admission. The respondent was taken there in a police car with the appellant and other police officers and in due course was admitted to the hospital, examined by the superintendent, treated and detained for some six days.
