疑罪,顾名思义就是,司法机关不能确定犯罪嫌疑人或被告人是否构成犯罪。对其疑罪的处理自古以来就有很多处理制度,例如奴隶之下的疑罪从神,封建制下的疑罪从赦、疑罪从赎等。在这些原则处理下,国家的刑罚权被无限制的滥用,继而刑讯逼供的行为也应运而生。在我国当代的司法制度下,疑罪从无的原则在我国法律中已有体现,但还有很多不完善的地方,本文以疑罪的概念为切入点,深入的探讨了疑罪从无的理论基础及我国适用疑罪从无的现状。最后对我国疑罪从无原则的适用提出几点意见。 Suspected crime, as the name suggests, is that the judiciary can not determine whether a criminal suspect or a defendant is a crime.

Based on the concept of the crime of doubt, Theoretical Basis and Status Quo of Applying Suspect in Our Country. At last, I put forward some opinions on the application of the principle of no crime in our country.
