摘要： 冤案是指已生效的裁判对无罪者判定为有罪的案件。冤案是最大的司法不公。冤案难以避免，但不能以此为借口而不加严防。为此，必须杜绝刑讯逼供，保证辩护权的充分行使，运用证据准确认定案件事实，坚持疑罪从无原则，正确处理三机关关系，确保独立行使审判权、检察权。

Abstract: Wrongful conviction is such a case where an innocent person is convicted by an effective judgment. It is  the worst form of miscarriage of justice. We should not refuse to take strict precautions against wrongful conviction. To prevent wrongful conviction, we should prohibit extortion of confessions by torture，guarantee the fully exercise of the right to defense, determine facts accurately by evidence, insist the principle of“in dubio pro reo”, handle the relationship correctly between the People’s Courts, the People’s Procuratorates and   the public security organs, and ensure the independence of judicial power and procuratorial power.

Key words: Wrongful Conviction, Extortion of Confessions by Torture, Right to Defense, Determine Facts Accurately
