A board of county commissioners (BOCC) has the authority to establish positions (RCW 36.16.070) and, as such, also has the authority to abolish positions. In Smith v. Board of Walla Walla County Comm’rs, 48 Wn. App. 303, 307 (1987), the court, in relevant part, held:
It is undisputed that the Board of County Commissioners have the authority to eliminate and establish employee positions in a county department, to reduce department budgets, and to create new departments. See RCW 36.32.120(6); RCW 36.16.070; see also Miller v. Pacific Cy., 9 Wn. App. 177, 179, 509 P.2d 377 (1973). There is also no dispute the County was facing a serious budget shortfall. The Board’s acts in balancing the budget were clearly discretionary. Therefore, mandamus would be appropriate only if the Board’s actions were properly found to be arbitrary and capricious.
In general, it is within the discretion of a BOCC to allocate, as it sees fit, the financial resources of the county as provided in the budget it approves. This principle is well-illustrated in State ex rel. Farmer v. Austin, 186 Wash. 577, 588 (1936)
In the light of the known financial difficulty of the counties and considering the circumstances of the times, the court cannot say that an order reducing the force of deputies in the sheriff’s office from six to four was so capricious and arbitrary as to be void. It may be that the action of the majority of the board of county commissioners was improvident and ill-considered, but, if so, the remedy lies with the electors rather than in the courts. If it be assumed that the business of the sheriff’s office will be hampered by the reduction in force, the harm will not be nearly as great as would be the consequences of the interference by the courts with the executive duties of the board of county commissioners, in whom is reposed the financial management of the county’s affairs.
As such, the courts will interfere with this exercise of discretion only upon the theory that the action is so capricious and arbitrary as to evidence a total failure to exercise discretion and is, therefore, not a valid act. Arbitrary and capricious action has been defined by the courts as “willful and unreasoning action, without consideration and in disregard of facts or circumstances.” See, e.g., Schrempp v. Munro, 116 Wn.2d 929, 938 (1991). See also, Miller v. Pacific County, 9 Wn. App. 177, review denied, 82 Wn.2d 1012 (1973) (“When the [board of county] commissioners, by resolution, show a clear purpose to effect a reduction of a department’s budget, they act within the ambit of the discretionary power granted to them.”)
Of course, the other elected county officials have statutory responsibilities they must carry out, and they need staff and facilities to carry them out, but there will most always be disagreement as to how much money they actually need in their budgets to do so. The statutes vest the BOCC with the authority to make that determination in the county budget. And, absent arbitrary and capricious action by the board in setting the budget, its budgetary decision-making will be upheld by the courts.
Note, however, that once a position has been funded, the authority to hire (or terminate) a particular individual rests with the elected official (not the BOCC). See Osborn v. Grant County, 130 Wn. 2d 615, 621 (1996), quoting Thomas v. Whatcom County, 82 Wash. 113 (1914). Thomas held that, once the board has authorized the hiring of deputies in a county office, "the officer in whose office the deputies are to serve, being responsible on his bond for their conduct, has the absolute right to determine the personnel of such deputies . . . ."
Of particular interest to you may be a recent Attorney General’s Opinion that analyzes the BOCC’s authority relative to the Sheriff’s Office under RCW 36.16.070 and chapter 41.14 RCW. See AGO 2017 No. 3. The opinion addresses several questions, but upholds the principle that the County Commissioners have the authority to ultimately create positions authorized by chapter 41.14 RCW.
