The criminal adjudication in this country has so far been put solely at the hands of professional judges without the people taking a role in it. The Justice Yuan has felt the need to introduce the people to the adjudication, and has then since 1988 started to deliberate the possible ways to enable the people to participate in the adjudication, and also, on the basis of the current legal system, consider relevant adaptations. In 2010, it further attempted to promote the lay judge system in Taiwan, and accomplished in 2012 the draft of “the provisional regulations for the lay judge of the people,” is now on the agenda of the Legislation Yuan for review. It is hoped that the people’s trust with the Justice will be promoted by this provisional regulations. Before, however, all such foreign institutions as jury and lay assessor system are adopted, issues ensue: do they comply with the Constitution? And is this draft of the provisional legislations suitable for the purpose for which the people are to be brought to participate in the adjudication? And, can the drafted regulations really improve the people’s understanding of, and trust with, the Justice? This essay suggests that they all need to be put under scrutiny.
