tie vote; equal number of votes for and against
Formal term used in meetings, committees, or legislative contexts when the number of affirmative and negative votes is equal. Rare in everyday conversation.
The vote resulted in a tie, and the decision was left to the chairperson.
Synonymous, also formal and rare. 賛否同票 is slightly more common in parliamentary contexts.
Compound of 賛否 (approval and disapproval) and 同票 (same votes). The exact historical derivation is uncertain, but the term is used in modern formal settings.
