“毒树之果”在我国的适用及完善建议
The Application and Improvement Suggestions of “Poisonous Tree Fruit” in China

“毒树之果”是派生于刑事诉讼中非法证据排除规则的一个重要规则，源于美国的司法实践，但是我国并未作出相关规定。该规则的确立有利于发现案件真相，防止冤假错案，尊重和保障被告人的权利，因此本文主要通过对国外非法证据排除规则的适用情况进行分析，从中借鉴有益经验并结合中国的基本国情提出建议，以完善中国的非法证据排除规则，希望对我国的法治进步作出贡献。
The “Fruit of the Poison Tree” is an important rule derived from the rule of excluding illegal evidence in criminal proceedings, originating from judicial practice in the United States, but China has not made relevant provisions. The establishment of this rule is conducive to discovering the truth of the case, preventing injustice, falsehood, and wrongs, respecting and protecting the rights of the defendant. Therefore, this article mainly analyzes the application of foreign illegal evidence exclusion rules, draws on useful experience, and proposes suggestions based on China’s basic national conditions to improve China’s illegal evidence exclusion rules, hoping to contribute to the progress of the rule of law in China.
