This paper is concerned with the implications of CJEU internal market case law for the balance of powers between the EU institutions. It argues that the Court’s case law involving the areas of domestic policy reserved by the Treaty predominantly for the competence of the Member States creates an inter-institutional dynamic that restrains the rule-making capacity of the EU legislature. This dynamic seems to undermine the EU law principle of institutional balance because it either (i) prevents EU-level legislative action, or (ii) predetermines its content, or (iii) makes it devoid of practical force through expansive judicial interpretation of secondary legislation.

塑造内部市场的力量：CJEU判例法对欧盟机构平衡的启示

本文涉及CJEU内部市场判例法对欧盟机构之间权力平衡的影响。它认为，法院的判例法主要涉及成员国的权限，涉及条约所保留的国内政策领域，这产生了一种机构间的动力，从而制约了欧盟立法机关的制定规则的能力。这种动态似乎破坏了欧盟法律关于制度平衡的原则，因为它要么（i）阻止了欧盟一级的立法行动，要么（ii）预先确定了其内容，或者（iii）通过对二级立法进行广泛的司法解释而使其缺乏实际力量。
