If at any time after the creation of an eligible list, the Commission has reason to believe that any person whose name appears on such list has in any manner become disqualified for appointment because of incapacity developed subsequent to his examination, because of false statements made in his application or for other just and reasonable cause, such person shall be notified and given an opportunity to be heard. If such person shall fail to appear for such hearing, or it be established at such hearing that such eligible is disqualified or incapacitated for appointment, his name shall be removed from the eligible list.
Names may be removed from an eligible list by action of the Commission for the following reasons in addition to those heretofore considered:
(a) Request of the eligible:
(b) Failure to accept appointment upon certification unless a waiver of such certification is granted by the Commission;
(c) Three different certifications without receiving appointment;
(d) Upon resignation from promotional eligibility lists;
(e) When an eligible person's name appears on more than one list, appointment to a position in one class may be considered a waiver for appointment from other lists for classes the salary of which is equal or lower;
(f) Any other just or reasonable cause as determined by the Commission.
(Amended 2-21-78.)
