本文介紹並評論民國100年之法制與實務發展。最值得記載者，為最高法院就量刑程序之精緻化、當事人進行主義之落實，作出幾則傳世的經典性判決，在法律史上，絕對佔有重要及正面之一頁。惟最高法院庭數太多，常出現互為矛盾之見解，令人民及下級法院不知所從，對司法傷害甚劇，民眾詬病最深，亦最需改革。司法院鑼鼓喧天地推動「觀審制」，激發熱烈論戰，亦佔據媒體大幅版面。主政者勢在必行之顢頇，汲汲展現政治業績之野心，已完全淹沒法律之理性辯論，將來發展仍待觀察。

The paper introduces and evaluates the important developments of Taiwan's criminal procedure law in 2011. The Supreme Court delivered two revolutionary and historical decisions in 2011. One is the trial courts have no more duty to investigate evidence unfavorable to the accused. Before this decision, it is unclear whether trial courts have such a duty. In order to avoid reversal of judgments, most trial courts would investigate evidence favorable and unfavorable to the accused, which is the inquisitorial tradition. Another important decision is to impose more duty on trial judge in sentencing, especially in death penalty cases. The Supreme Court declared when the prosecutor seeks death penalty, the trial court must hear arguments for and against it from parties. In addition, when the trial court imposes a death penalty, it must explicitly explain why it could not impose other sentence, such as life imprisonment, than the death penalty. Another important development is the Judical Yuan's policy in adopting lay people's participation in trial. Nonetheless, under the Judicial Yuan's plan, the trial judges could veto the lay people's decison. For this reason, the academics criticize the proposed model is not in the nature of real lay people's participation.
