An acclamation is a form of election that does not use a ballot. It derives from the ancient Roman word acclamatio, a kind of ritual greeting and expression of approval towards imperial officials in certain social contexts.
Voting
Voice vote
The most frequent type of acclamation is a voice vote, in which the voting group is asked who favors and who opposes the proposed candidate. In the event of a lack of opposition, the candidate is considered elected. In parliamentary procedure, acclamation is a form of unanimous consent.[1]
In Canada, a candidate for a parliamentary, legislative or municipal position is said to be elected by acclamation if he or she has no opponents for the seat, an eventuality that rarely occurs federally, but is more common in legislative elections in the northern territories and municipal elections.
Acclamations were ritual verbal expressions of approval and benediction in public (like gladiatorial games) and private life. The departure and return of imperial magistrates was, for example, accompanied by acclamation. In the later Roman Empire, expressions of goodwill were reserved for the emperor and certain relatives, who were greeted in this manner during public appearances on special occasions such as their birthdays. By the 4th century AD, acclamations were compulsory for high-level imperial officials.
