Holding over after expiration of term

§ 5. Holding over after expiration of term. Every officer except a
judicial officer, a notary public, a commissioner of deeds and an
officer whose term is fixed by the constitution, having duly entered on
the duties of his office, shall, unless the office shall terminate or be
abolished, hold over and continue to discharge the duties of his office,
after the expiration of the term for which he shall have been chosen,
until his successor shall be chosen and qualified; but after the
expiration of such term, the office shall be deemed vacant for the
purpose of choosing his successor. An officer so holding over for one or
more entire terms, shall, for the purpose of choosing his successor, be
regarded as having been newly chosen for such terms. An appointment for
a term shortened by reason of a predecessor holding over, shall be for
the residue of the term only.
