Administrative Litigation Act Article 192

Where one of the grounds of attack or defense presented separately is mature for decision, the administrative court may enter an interlocutory judgment; the same applies to cases where the ground and amount of a claim are both disputed and the administrative court finds the ground just.
中文原文 行政訴訟法第192條
各種獨立之攻擊或防禦方法,達於可為裁判之程度者,行政法院得為中間判決;請求之原因及數額俱有爭執時,行政法院以其原因為正當者,亦同。
