If only one person is nominated for Speaker, he is called to the chair without a vote. If more than one, they are voted upon successively, a majority being required for election.[259:1] The proposer and seconder are always private members, for it is considered more fitting that the ministers should not be prominent in the matter.[259:2] The Speaker is, however, always selected by the government of the day, and a new Speaker is always taken from the ranks of the party in power. Sometimes the election is not uncontested, and this happened when Mr. Gully was chosen in 1895. But although the Speaker may have been opposed when first chosen, and although he is elected only for the duration of the Parliament, it has now become the invariable habit to reëlect him so long as he is willing to serve. The last cases where a Speaker's reëlection was opposed occurred in 1833 and 1835, and on the second of those occasions he was defeated. The principle is well illustrated by the career of Mr. Gully. He was elected by a small majority, during the last few months of a moribund Liberal cabinet. His selection had not pleased the Conservatives, and he was warned that they held themselves at liberty not to reëlect him if they came to power in the next Parliament. Contrary to the ordinary rule his constituency was contested at the next general election, but although the Conservatives obtained a large majority in the new Parliament, he was returned to the chair without opposition. [Sidenote: His Powers over Debate.] The Speaker is purely a presiding officer. He has nothing to do with appointing any committees, or guiding the House in its work. He is not a leader but an umpire, otherwise he could not remain in the chair through changes of party. As an umpire, however, his powers are very great, and in some cases under the modern changes in the standing orders they are autocratic. He decides, for example, whether a motion to closure debate may be put, or whether it is an infringement of the rights of the minority;[260:1] he can refuse to entertain a dilatory motion if he considers it an abuse of the rules of the House;[260:2] and he can stop the speech of a member who "persists in irrelevance, or tedious repetition."[260:3] Moreover, from his decision on those matters, or on any points of order, there is no appeal.[260:4] The House can suspend or change its own rules by a simple majority vote, but it cannot in a concrete case override the Speaker's construction of them.[260:5] This is a general principle of English parliamentary law, which is applied in almost all public bodies.[261:1] It may render a conscientious man more careful in his rulings, but it certainly places in his hands enormous power.
