No, a city council does not have a role in reviewing changes to civil service rules adopted by the civil service commission. In general, a civil service commission has authority to adopt and to change or revise its civil service rules, consistent with state law applicable to civil service, including Chapter 41.08 RCW (for city firefighters) and Chapter 41.12 RCW (for city police).
There is no legal authority for a city council to approve or not approve the civil service rules. I understand this is because civil service in local government was originally created to curb political favoritism and remove the coercive pressures that once caused public employees to contribute money and time to partisan political candidates. Civil service rules establish an even playing field of open competition for positions with hiring and promotions based on merit and demotions, suspensions, or terminations only for cause. For more information, see MRSC’s Civil Service page.
RCW 41.08.040(1) provides the legal authority for the civil service commission (for firefighters) to make its own rules and regulations:
It shall be the duty of the civil service commission:
(1) To make suitable rules and regulations not inconsistent with the provisions of this chapter. Such rules and regulations shall provide in detail the manner in which examinations may be held, and appointments, promotions, transfers, reinstatements, demotions, suspensions and discharges shall be made, and may also provide for any other matters connected with the general subject of personnel administration, and which may be considered desirable to further carry out the general purposes of this chapter, or which may be found to be in the interest of good personnel administration. Such rules and regulations may be changed from time to time. The rules and regulations and any amendments thereof shall be printed, mimeographed or multigraphed for free public distribution. Such rules and regulations may be changed from time to time. [Emphasis added.]
See, also, RCW 41.12.040(1) for law enforcement.
