Eligible lists, unless earlier exhausted, shall be in effect for 24 months from the
date the list was approved by the commissioner of human resources in accordance with section 114-246. Eligible lists shall not be extended beyond their expiration date, and all vacancies
existing on the expiration date shall be filled from the eligible list; however, section 114-249(b) shall still apply. A new examination announcement, as provided for in section 114-234, will be published as determined by the commissioner of human resources 180 days
before the expiration of a list or after a list is exhausted, which ever shall be
earlier. When a new examination announcement has not been published following the
expiration of a list, a written notice explaining the reasons for such failure to
publish a new announcement shall be given to all sworn members of the affected department,
the mayor and the appropriate legislative oversight committee within 30 days after
a list has expired.
