The changes to the Irish exclusionary rule introduced by the judgment in People (DPP) v JC mark an important watershed in the Irish law of evidence and Irish legal culture more generally. The case relaxed the exclusionary rule established in People (DPP) v Kenny, one of the strictest in the common law world, by creating an exception based on ‘inadvertence’. This paper examines the decision through the lens of legal culture, drawing in particular on Lawrence Friedman's distinction between ‘internal’ and ‘external’ legal culture to help understand the factors contributing to the decision. The paper argues that Friedman's concept and, in particular, the dialectic between internal and external legal culture, holds much utility at a micro as well as macro level, in interrogating the cultural logics at work in judicial decision-making.

通过法律文化解读变革：以爱尔兰排除规则为例

法院判决对爱尔兰排除规则的修改人民（民进党）诉 JC标志着爱尔兰证据法和爱尔兰法律文化的一个重要分水岭。本案放宽了人民（民进党）诉肯尼，通过创建基于“疏忽”的例外，是普通法世界中最严格的法律之一。本文从法律文化的角度审视了决策，特别借鉴了劳伦斯·弗里德曼对“内部”和“外部”法律文化的区分，以帮助理解促成决策的因素。本文认为，弗里德曼的概念，特别是内部和外部法律文化之间的辩证法，在审视司法决策中的文化逻辑时，在微观和宏观层面都具有很大的实用性。
