What does all that mean? There is something more to this amendment than might appear on the face of it. Ostensibly it means just what it says, namely, it makes it possible for a member of the authority's staff to fill in for the chief executive in his absence when the position is vacant. By implication, it actually prevents, and is intended by me to prevent, the functions of the chief executive being assumed on a temporary basis by the chairman of the authority. Recent history has shown several examples of this practice taking place in State bodies. I do not want to dwell unduly on these experiences other than to say that we should strongly discourage that practice. We could guarantee through legislation that it does not happen.
