An issue which arose during the inquiry by the Senate Select Committee on a Certain Maritime Incident was the ability of the committee of one House of Parliament to compel the attendance before it of a person who had been a minister serving as a Member of the other House. A related issue was the status of that persons then ministerial advisers. The Clerk of the House of Representatives was called on to provide advice on the matter. Other opinions, some of which appear in an appendix of the committee's report, were also offered and are published here.
