行政国家的兴起导致立法机关授予行政机关宽泛的裁量权力。这直接冲击着传统的权力分立理论。强调权力分立理论的消极面向,即防止权力集中的要求已经无法有效回应行政裁量权大量存在的问题。对此现象,唯有对权力分立理论进行功能主义的解释才能回应。在广泛授予行政裁量权不可避免的情况下,分权理论之消极面向应被弱化,以权力制约权力的积极面向应予以强化。就立法控制行政裁量而言,立法的事前控制应从实体转向程序;事后控制应从个案监督转向对行政规则的控制。 The rise of the administrative state led the legislature to grant the executive authorities a broad discretionary power. This has a direct impact on the traditional theory of separation of powers. Emphasizing the negative aspects of the theory of separation of powers, that is, the requirement of preventing concentration of power has been unable to effectively respond to the large number of problems of administrative discretion. To this phenomenon, only functional interpretation of the theory of the separation of powers can respond. Under the circumstance of extensively granting administrative discretion inevitably, the negative aspect of decentralization theory should be weakened and the positive aspect of power should be strengthened. In terms of legislative control of administrative discretion, the ex ante control of legislation should shift from substantive to procedural; ex post control should shift from case supervision to control of administrative rules.
