Proof, defense, or support for one's argument or position. Often used in the negative to mean the opposite. The truth is that the prosecution hasn't got a leg to stand on, now that their key witness was discredited in court.
证明,防御,或为自己的论点或立场的支持。在负经常用来表示相反。事实是,检察机关还没有得到一个自顾不暇,现在他们的关键证人在法庭上抹黑。
The senator's company avoided paying millions in taxes over the years, so she doesn't have a leg to stand on when she criticizes tax dodgers.
参议员的公司避免支付多年来税款数以百万计,所以她没有一条腿站立时,她批评逃税。
