The 2x1 law (Spanish: Ley del 2x1) was an Argentine law. It was sanctioned in 1994, and established that prisoners detained without a definitive sentence would be benefited from the second year onwards, so that their days as detained would count as the double. The original purpose of the law was to guarantee a swift sentence. Many lawyers exploited the law by using pettifoggery to delay sentences, so that the prisoners would be benefited by it. The law was derogated in 2001.
