The advantage of this system is that, with a single judge supervising the entire case, the judge will be thoroughly familiar with both the evidence and the participants, and will be in a good position to make a clear judgment of their credibility.
這個制度的優點是：法官對接手案件的內容及證據瞭解得十分透徹，開庭偵訊也較有時間「察言觀色」，從原告、被告等人講話的表情、反應來判斷他們說的是真話還是假話，裁判結果更能接近公平與客觀。
