It must be borne in mind that the substance of the work of the authority will be carried out by the executive of the body rather than the board. Furthermore, some of the work will be done by sub-committees of the board which could, if necessary, include members of the prescribed accountancy bodies or experts who are not members of the board. The independence of the authority is an over-riding consideration and it is essential for us, as regulators, to ensure that the authority is constituted so as to obviate any possible claim of bias against it.
