自成本效益分析建構科技偵查立法框架之理論嘗試──由GPS與M化車偵查相關判決談起

A Theoretical Attempt to Establish the Legislative Framework for Technology Investigation

本文主題是嘗試建構科技偵查的立法框架。首先，本文分析目前與GPS及M化車等偵查手段相關的判決，指出我國法院採取以保障隱私權為中心的論述模式。接著，本文從判決過度聚焦被偵查者隱私權保障、比例原則存在方法論上的問題、社會與科技發展脈絡下的隱私概念變化等三個面向出發，說明法院所採論述模式不適於用來發展科技偵查的立法框架。最終，本文從成本效益分析的角度出發，建立初步的分析模型，並指出未來我國立法應注意之處。

The main issue of this article is to establish the legislative framework for technology investigation. At first, this paper analyzes the current judicial precedents regarding on investigation methods such as GPS and IMSI catcher, and points out that Taiwanese courts have adopted a analysis model centered on ensuring privacy. Next, I will point out the problems of this model from the viewpoints of“too much attention to the privacy of the subject to be investigated”,“methodological problems of the principle of proportionality”and“changes in the concept of privacy in the social context”. Moreover, I will argue that the model adopted by the Taiwan courts is not suitable for legislation of technology investigation law. At last, Finally, I will establish the legislative framework for technology investigation from the perspective of cost-benefit analysis and points out the important points to note about the legislation of technology investigation law.
