A review of the role and function of the Mental Health Act Commission is a natural outcome of the first five years experience of its workings. By the Autumn, when the third Biennial Report will be published, the new direction and operation of the Commission will be determined by the Secretary of State for Health on the basis of the recommendations of the review. It is too early to indicate the changes that are likely to be wrought by this development. It is possible, however, to reflect on the activities to date.
