On April the 9th 2014, the European Commission published a package of measures for corporate law and the further development and improvement of corporate governance in the European Union. This includes, inter alia, a proposal for a directive amending the 2007/36/EC shareholders' directive. The planned amendments relate, in addition to a reorganization of the requirements for the remuneration of the Executive Board and the introduction of legal bases for proxy advisors, also regulations concerning Related Party Transactions. This refers to legal transactions between a stock exchange listed company and such closely related persons and / or related companies. However, such legal transactions are not to be completely prevented but made more transparent and, by prescribing additional authorizations, less susceptible to possible manipulation. The proposed amendment provides for a two-pronged regulatory model: major transactions of the company with related parties are to be published before their implementation in order to facilitate the control of these legal transactions to the non-participating shareholders (publicity obligation). Legal transactions of particularly great relevance are not only to be published, but also to the participation of other bodies than the Management Board (authorization obligation). Within the scope of this diploma thesis, the unions legislation on Related Party Transactions will be discussed in more detail before the legal situation in Austria and other legal systems is discussed. This is followed by a discussion of the factual and personal scope of the planned regulation as well as a detailed description of the obligation to publish and approve.
