Section 25 - Powers of state civil service commission with respect to local rules; appointments and eligible lists1. The state civil service commission may, by unanimous vote of the three members (a) amend or rescind any rule, regulation or jurisdictional classification prescribed by a municipal commission, but shall not exempt from competitive examination any office or position in any civil division without the consent of the municipal commission having jurisdiction;(b) rescind any appointment in the classified service of a civil division;(c) remove from any eligible list established by a municipal commission the name of any person thereon; and(d) rescind any examination or eligible list or cancel an appointment already made from a list so rescinded.2. The state civil service commission, however, shall not take such action upon any ground other than that the provisions of this chapter are not properly or sufficiently carried out, nor without specifying in writing the particulars in which such provisions are not carried out. Before any such action is taken, the state civil service commission shall state the reasons for such action in writing and file a certified copy thereof in the office of the municipal commission concerned, which shall be a public document therein, and shall give to such commission and the person aggrieved thereby a reasonable opportunity to present facts in opposition to such action.
