(b) a report of the result of the examination has been furnished by the medical practitioner to the Board; and
(c) the Board is satisfied, after considering the report of the medical practitioner, that the health and physical fitness of the person are such as to justify his being accepted as a contributor to the Fund under Part III or to the Provident Account, as the case may be.
