But an elective officer must be given "an opportunity to be heard in his own defense." A vacancy in the office of mayor or alderman is filled by a new election.
A vacancy in any other office is filled by appointment.

The person elected or appointed serves for the unexpired term.
The Mayor is the chief executive officer and head of the police of the city.

By and with the consent of the council, he appoints a chief of police and other police officers and watchmen.

In case of disturbance he may appoint as many special constables as he may think necessary, and he may discharge them whenever he thinks their services no longer needed.
The City Council consists of the aldermen.

[Footnote: In some states the city council consists of two bodies.] It is the judge of the election of its own members.
