(_a_) An eligible who is so defective in sight, speech, or hearing,
or who is otherwise so defective physically as to be apparently unfit to
perform the duties of the position to which he is seeking appointment.
(_b_) An eligible who has made a false statement in his
application, or been guilty of fraud or deceit in any matter connected
with his application or examination, or who has been guilty of a crime
or of infamous or notoriously disgraceful conduct.
3. If an appointing or nominating officer to whom certification has been
made shall object in writing to any eligible named in the certificate,
stating that because of physical incapacity or for other good cause
particularly specified such eligible is not capable of properly
performing the duties of the vacant place, the Commission may, upon
investigation and ascertainment of the fact that the objection made is
good and well founded, direct the certification of another eligible in
place of the one to whom objection has been made.
