"(4.) Subject to sub-section (7.) of this section, in making an inquiry the Authority shall give any waterside worker who appears to the Authority to be directly concerned an opportunity of presenting to the Authority a statement of any facts and contentions material to the inquiry but the Authority may require any such statement to be submitted in writing.
"(5.) In giving a waterside worker an opportunity of presenting to the Authority a statement for the purposes of an inquiry, the Authority shall serve on the waterside worker a notice setting out the matters to be inquired into, the fact that he may present the statement and:
(a) in the case of a n oral statement -- the person to whom, and the place, date and time at which, the statement is to be made; and
(b) in the case of a written statement -- the address to which, and the period within which, the statement is to be delivered.
"(6.) The Authority may make one inquiry into matters concerning any number of waterside workers if it appears to the Authority that those matters arose, or may have arisen, out of acts or things done or omitted to be done on the same day by those waterside workers, or by a substantial number of those waterside workers, in concert, or at the direction or instigation of a Union, a branch of a Union or an officer or member of a Union or of a branch of a Union.
"(7.) Where, for the purposes of an inquiry referred to in the last preceding sub-section, it appears to the Authority that a substantial number of waterside workers is concerned, the Authority may, if it considers that by so doing it will become apprised of all the facts and contentions material to the interests of those waterside workers in relation to the inquiry, give an opportunity of presenting statements as to those facts and contentions to some only of those waterside workers, being persons whose statements would, in the opinion of the Authority, present all those facts and contentions.
"(8.) Where, for the purposes of an inquiry, the Authority is required by the preceding provisions of this section to serve on a substantial number of waterside workers notices setting out any matters, it is a sufficient compliance with that requirement if the Authority notifies the waterside workers concerned of those matters by any of the means by which those waterside workers would usually be notified of their allotment to stevedoring operations.
