N.D. Cent. Code § 54-40.4-09
On the first day of January following repeal of a county-city home rule charter any affected county and city reverts to the form of government in place immediately preceding adoption of the home rule charter. If positions to which officials were elected under the home rule charter are substantially the same as positions under the form of government to which the county and city revert upon repeal, the elected officials shall continue to exercise the authority of their positions for the salary prescribed by the home rule charter until expiration of their terms of office as prescribed by the home rule charter. An amendment of a home rule charter may not diminish the term for which any official was elected, redesignate that elected office during that term as appointed, or reduce the salary of the office for that term.
