Casting vote。其中文意思可以表述为：一票通过的表决权、（会议主席在赞成票和反对票票数相等时所投的）决定票。

定义

为了加深对这个术语的认识，我们先从其英文定义入手，参见《布莱克法律词典》定义：

Where the votes of a deliberative assembly or legislative bodyare equally divided on any question or motion, it is the privilege ofthe presiding officer to cast one vote (if otherwise he would not be entitledto any vote) on either side, or to cast one additional vote, if he has already voted as a member of the body. This is called the “casting vote.”

如果议会或立法机构的表决在任何问题或议案上形成票数均等的状态，则主持人有权在任何一方投一票（否则他将无权投票），或者如果他已经作为该机构的成员进行了投票，则他可以再投一票。这就是所谓的“一票通过的表决权”。

参见实例

Unless otherwise agreed upon in the Agreement, any resolution adopted by the board of directors shall be approved by more than half of the directorspresent at the meeting. The chairman does not have a casting vote.

除本协议另有约定外，董事会通过的任何决议应经出席会议的半数以上董事同意通过。董事长不持有一票通过的表决权。
