Both Houses may decide questions by voice vote; members shout out "Aye!" and "No!" in the Commons—or "Content!" and "Not-Content!" in the Lords—and the presiding officer declares the result. The pronouncement of either Speaker may be challenged, and a recorded vote (known as a division) demanded. (The Speaker of the House of Commons may choose to overrule a frivolous request for a division, but the Lord Speaker does not have that power.) In each House, a division requires members to file into one of the two lobbies alongside the Chamber; their names are recorded by clerks, and their votes are counted as they exit the lobbies to re-enter the Chamber. The Speaker of the House of Commons is expected to be non-partisan, and does not cast a vote except in the case of a tie; the Lord Speaker, however, votes along with the other Lords. Speaker Denison's rule is a convention which concerns how the Speaker should vote should he be required to break a tie.
