“jeopardy”危险，具体而言，指在审判过程中刑事被告人面临的被定罪和判刑的危险。通常在陪审团审判的情况下，从组成陪审团起，在由法官审判的情况下，从第一个证人宣誓时起，被告人即开始面临这种危险。有时也称作「legal jeopardy」。

“double jeopardy”双重危险；双重追诉。指对实质上同一的罪行给予两次起诉、审判、定罪或科刑。禁止对当事人的同一罪行进行双重追诉是英美法上一项重要的诉讼原则。美国宪法第五条修正案具体规定了这一原则，美国最高法院则通过判例确认该原则对在第一次起诉后被法院定罪或宣告无罪的被告人均适用，并通过宪法第十四条修正案，即「正当程序条款」，而将该原则扩大适用于各州。Double jeopardy is a procedural defence (primarily in common law jurisdictions) that prevents an accused person from being tried again on the same (or similar) charges following an acquittal in the same jurisdiction.[1] A variation in civil law countries is the peremptory plea, which may take the specific forms of autrefois acquit ('previously acquitted') or autrefois convict ('previously convicted'). These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem ('not twice against the same').

former jeopardy，先前的危险(处境)，也称「双重危险(处境)」〔double jeopardy〕。不受双重危险，即不能因同一罪行而多次受审的抗辩，是被告人在普通法上的一项基本权利和宪法权利，用以保护被告人不因同一罪行而再次受审和被定罪。美国联邦宪法第五条修正案对此有明确规定。但由联邦政府和州政府提出的控诉，则不受此项宪法保护的限制。Former jeopardy means that a man cannot be tried for an offence more than once. 

这两者也体现了我国刑法中的“一罪不二审”的原则。因此“一罪不二审”的英文也可以用double jeopardy 来表示。

以下为相关双语示例：

In some countries, double jeopardy did not apply where there was a determination that it was an international crime or where the judgement rendered abroad was not based on a request from the forum State (e.g., Finland) or if, subject to the permission of a designated authority, the act was not punishable in both States at the time an act was committed, it was considered a criminal offence according to the customary rules and principles recognized by the international community (e.g., Slovenia).

在一些国家，一罪不二审原则在下列情形下不适用，罪行被定为国际犯罪，或国外做出的判决不是基于法院地国的请求(如芬兰)，或在犯下罪行的时候，该 行为在两国都无法受到惩罚，而根据国际社会承认的习惯规则和原则，此行为被 认为是刑事犯罪(须经指定主管部门准许)(如斯洛文尼亚)。
