Introduced in 2009, Article 399 § 3 of the Commercial Companies Code empowers shareholders representing at least half of the share capital or at least half of the total votes in the company to independently convene an extraordinary general meeting. In a corporate conflict situation, this provision may constitute a serious instrument in the hands of investors struggling to acquire or restore control over the company as quickly as possible; however, it has not yet been analysed in detail or interpreted consistently. Doubts concern both: who is the subject of the referred competence and the prerequisites for exercising it, including the crucial notion of representing "half of the total of votes". This article, which strives for a functional, adaptive interpretation of these prerequisites, is intended as a contribution to the further discussion on this topic.
