2. State offices. In all state offices, judges of courts of record, officers, trustees, inspectors, and members of all boards or commissions, and all persons filling any position of trust or profit in the state, by the governor, except when some other method is specially provided. An appointment by the governor to fill a vacancy in the office of lieutenant governor shall be for the balance of the unexpired term. An appointment made under this subsection to a state office subject to section 69.13 shall be for the period until the vacancy is filled by election pursuant to law.

5. Elected township offices.
a. When a vacancy occurs in the office of township clerk or township trustee, the vacancy shall be filled by appointment by the trustees. All appointments to fill vacancies in township offices shall be until a successor is elected at the next general election and qualifies by taking the oath of office. If the term of office in which the vacancy exists will expire within seventy days after the next general election, the person elected to the office for the succeeding term shall qualify by taking the oath of office within ten days after the election and shall serve for the remainder of the unexpired term, as well as for the next four-year term.
b. However, if the offices of two trustees are vacant the county board of supervisors shall fill the vacancies by appointment. If the offices of three trustees are vacant the board may fill the vacancies by appointment, or the board may adopt a resolution stating that the board will exercise all powers and duties assigned by law to the trustees of the township in which the vacancies exist until the vacancies are filled at the next general election. If a township office vacancy is not filled by the trustees within thirty days after the vacancy occurs, the board of supervisors may appoint a successor to fill the vacancy until the vacancy can be filled at the next general election.
