27. Power of majority and person presiding

Whenever, by or under any written law, a power is conferred or a duty imposed on a body or number of persons consisting of, or being not less than three, the power may be exercised or duty discharged in the name of that body or number of persons by a majority of those persons.

Whenever such body is assembled, the chairman or other person presiding shall have a casting as well as a deliberate vote.

The exercise of any power vested in the body or number of persons may be signified either by the chairman or other person presiding at the meeting or other deliberation at which the power was exercised, or at which, as the case may be, authority to exercise it was conferred, or by any person from time to time authorised by the body or persons to signify the exercise of such power.
