比例原则是行政法的一项基本原则,是衡量政府行政行为是否合理的重要工具,这个理论在行政法上十分重要。笔者发现,无论是法学专业研究生入学考试、司法考试还是各级公务员考试,比例原则都有其“用武之地”。而且,比例原则是行政法中最具专业性和技术性的原则。 The principle of proportionality is a basic principle of administrative law. It is an important tool to measure the reasonableness of government administrative actions. This theory is very important in administrative law. I found that both the law graduate entrance examination, judicial examination or civil service examinations at all levels, the proportion of the principle has its “useless.” Moreover, the principle of proportionality is the most professional and technical principle in administrative law.
