Under the first option, the clerk is explicitly named a member of the board of review. An appointed non-resident clerk may serve on such a board of review since the statutes do not indicate that members must be residents of the municipality. Residency, however, is a qualification for serving on the citizens or optional board of review also authorized in sec. 70.46(1). Thus, if a municipality has established a citizens board of review, rather than the official or statutory board of review, a non-resident clerk would not be eligible for serving on the board, since it must consist of city or village residents. While the statute does state that a citizens board of review may include public officers and public employees, it appears such public officers or employees must also be residents of the city or village.
