As the chief presiding officer of the Legislative Assembly, the Speaker is expected to be impartial in chairing debates and ensuring orderly conduct in the Chamber. When in the chair, the Speaker may only vote in the case of a tie, i.e. a casting vote. Unlike Speakers in many other
Westminster system parliaments, when the Deputy Speaker or another member is in the chair, the Speaker may participate in debates and cast a deliberative vote. This is especially important in
hung parliaments. The Speaker is responsible for issuing writs for
state by-elections, warrants for parliamentary privilege offenders and bringing before the bar of the Parliament such offenders for rebuke or sentence. Among the office's ceremonial duties are representing the Legislative Assembly to the Crown (as by, for instance, presenting the Address in Reply to the Throne Speech) and to entities outside Parliament. Administratively, the Speaker has control of the Parliamentary Service and is responsible for the Parliament's budget, services, and administration. ==Deputies==
