Double Jeopardy，英美法术语，翻译为“一罪二审”。英美法中有“prohibition against double jeopardy”这一概念，即“禁止双重危险”，大陆法系国家称之为一事不再理，国际刑法中有时称之为“一罪不二审”、“一案不二理”等。

Double Jeopardy：placing someone on trial a second time for an offense for which he/she has been previously acquitted, even when new incriminating evidence has been unearthed. This is specifically prohibited by the Fifth Amendment to the U.S. Constitution, which states: "…nor shall any person be subject for the same offence [sic] to be twice put in jeopardy of life or limb…"

所谓“禁止双重危险”，其基本含义是一个人不能因同一行为或同一罪名受到两次或多次审判或处罚。禁止双重危险原则的渊源可以追溯到古罗马，中文通常称谓“一事不再理原则”。该原则在刑事诉讼中的运用称为禁止双重危险原则。一事不再理的原则是对同一行为，法院作出的判决发生法律效力后，除法律另有规定外，不得对行为人再行追诉和审判。

一事不再理原则适用于刑事案件和民事案件，而在刑事案件中，如果对一个案件进行重复的审判和处罚，将置被告人于又一次的危险之下，所以一事不再理原则在刑事司法中体现为禁止双重危险原则。

参考双语例句：

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)。
