(a) Except as otherwise provided by resolution or regulation of the commissioner of citywide administrative services, whenever a claim of manifest error or mistake is made, such claim shall be referred to a committee on manifest errors. This committee shall consist of three qualified persons designated as members thereof by the commissioner of citywide administrative services, which committee shall either have as a member or consult with an expert in the subject matter with which such claim is concerned. A claim of manifest error or mistake shall open for review the candidate's answers to all the questions in the examination. Such review may result in a higher or lower final rating.
(b) Such committee shall inquire into the merits of each claim and shall submit the signed determination of each member as to whether or not there has been a manifest error or mistake together with such correction or remedy, if any, as may be recommended.
(c) Except as hereafter provided, such claim of manifest error or mistake must be made in writing by the candidate within one month from the date of notice to the candidate of the results of such examination, tests, subjects or parts thereof.
(d) Whenever a claim of manifest error or mistake is made in connection with the rejection of a candidate because the candidate has failed to meet the preliminary requirements of such examination, such claim must be made in writing by the candidate within two weeks following the date upon which notice was transmitted to the candidate of such rejection.
(e) Whenever a claim of manifest error or mistake is made by a person on an eligible list who has been rejected after investigation because such person has failed to meet the preliminary requirements of such examination, such claim must be made in writing by the person within two weeks following the date upon which notice was transmitted to the person of such rejection.
(f) Any correction of manifest error or mistake shall be without prejudice to the status of any person previously appointed from the eligible list resulting from such examination. However, if, as a result of any correction of manifest error or mistake, an eligible on a list or any person appointed from such list is found to have failed the examination, any such eligibility or appointment shall be cancelled and revoked forthwith, and notice of such action shall be sent to the eligible or appointee. The right to cancel and revoke for the reasons set forth herein shall not apply where an appointee has served satisfactorily for a period of at least one year after appointment to such position.
